Understanding Mechatronics: A Beginner’s Guide for Freshers
If you’ve just stepped into the world of engineering or are considering which specialization to pursue, you might have come across the term Mechatronics. It sounds futuristic—and honestly, it is. But what exactly is it? Is it mechanical? Is it electronics? Or is it something else altogether?
Let’s break it down and make it simple for you.
What Is Mechatronics?
Mechatronics is an interdisciplinary field that blends mechanical engineering, electronics, computer science, and control engineering. It’s all about designing and creating smarter machines—systems that not only move or perform tasks but also think and respond intelligently.
Think of things like self-driving cars, robotic arms in factories, automated coffee machines, or even drones that maintain stability mid-air. All of these rely on the principles of mechatronics.
This discipline is becoming essential in today’s automation-driven world, especially with the rise of Industry 4.0, where machines communicate with each other to optimize performance without human input.
Why Should You Care as a Fresher?
In the early stages of your engineering journey, it's important to understand where the future is headed. Mechatronics is one of those areas that’s not just growing—it’s exploding.
As a fresher, you might still be figuring out what excites you most. But if you're someone who enjoys blending creativity with technology—imagine coding a program and then watching it control a real robot—this field will likely click with you.
Also, if you eventually want to work in automation, AI-driven systems, or robotics, mechatronics offers you the foundation and flexibility to go in multiple directions.
What Will You Learn in Mechatronics?
Typically, if you pursue mechatronics as a core subject or even as an elective, you’ll dive into areas like:
Sensors and Actuators: Devices that help machines sense their environment and act accordingly.
Microcontrollers and Embedded Systems: The brains of most modern electronic machines.
Mechanical Design: Basics of gears, motors, and structures that move.
Control Systems: How to ensure a robot does what it’s supposed to—no more, no less.
Programming: Often in C/C++ or Python to control the devices.
You may also get your hands on software like MATLAB, Simulink, or Arduino IDE early on.
How to Get Started in College
You don't have to wait till the third year to explore mechatronics. In fact, some colleges start offering related workshops and certifications right from the first year. If you're studying in a place where the labs are well-equipped and faculty are research-active, you'll probably get the chance to work on actual robots or automation systems before you graduate.
During a visit to a lab at NMIET Bhubaneswar, I noticed students working on automated vehicle prototypes that used sensors for obstacle detection. It struck me how mechatronics isn’t just a theoretical subject in such institutions—it’s hands-on and real.
Career Scope: Where Can Mechatronics Take You?
Mechatronics engineers are highly valued in sectors like:
Robotics and Automation
Aerospace
Automobile Manufacturing
Medical Equipment Development
Home Automation and Smart Devices
With increasing reliance on smart systems and AI-driven hardware, companies are actively seeking engineers who can work across domains. This is where mechatronics gives you a massive edge.
Even core mechanical or electrical engineers are now advised to pick up basic knowledge of microcontrollers or coding. So, if you're already in a college that encourages learning beyond your core, you're in the right place.
What Makes a Good College for Mechatronics Learning?
Let’s be honest—your learning environment plays a big role. Access to automation labs, exposure to industry tools, faculty who encourage innovation, and the chance to work on real-world projects—these are the things that matter most.
Some of the top engineering colleges in Odisha are already introducing mechatronics modules in mechanical and electronics streams. The goal is to create engineers who can build, code, and innovate.
It’s always a good idea to look into whether the institute collaborates with industries for internships and whether they have tie-ups for campus placements with companies involved in automation or robotics.
Final Thoughts: A Future-Proof Path
Mechatronics is not just another subject—it’s a mindset. It teaches you to look at machines not just as static components, but as intelligent systems that interact with the world.
As a fresher, you don’t need to master it all at once. Start with basic projects—maybe build a line-follower robot or an automatic light system. Join clubs, take up online certifications, and most importantly, stay curious.
If you’re in an environment where creativity and cross-disciplinary learning are encouraged—like the one I saw at NMIET—you’re already ahead of the curve.
So, if you’re dreaming of working on robots, smart devices, or even futuristic innovations we haven’t seen yet—mechatronics might just be the path you’ve been looking for.

Thrift store find, and a project:

Got this Alesis QX25 MIDI controller in as-is condition for $12. The most obvious problems when I got it were that the fader cap and one rotary encoder knob were missing, and one of the black keys was broken. In addition, there were solfege stickers on the keys, implying the previous owner was pretty young; that impression was backed up when I opened it to find maybe half a container of assorted glitter inside.

The fader cap I haven't come up with yet, and I've put a temporary knob on the encoder — the one at the far right — and I was able to partially disassemble the keybed and glue the key back together. (I'm using Gorilla Glue's superglue formulation, which is supposed to be better than usual cyanoacrylates at bonding plastics; if this doesn't hold, I know where to order replacements.) From a quick once over, the current status is that some of the tact switches are broken somehow — the ones, at least, for octave up and transpose down don't work. I've only given those the most cursory inspection, so I don't know if it's the switches themselves or something in the wiring; I'll have to see if my big box of tact switches has anything I can swap in for them.
But the "project" part is the part that has me enthused. Unlike a lot of more recent MIDI controllers, this one has both a USB jack for connecting to a computer and a 5-pin DIN jack for traditional MIDI instruments. It's also got a lot of spare room inside the case. So I'm looking at taking an Arduino or a Teensy and some little digital-to-analog converters and adding the ability to output CV and gate signals for modular synthesizers. Basically the Arduino will listen to the MIDI signal and interpret that; the minimal feature set is a single note off channel 1, just the CV and gate corresponding to the most recently struck key, but may expand to multiple notes and/or handling the drum pads as their own gate/trigger outs, and probably an extra CV out that can follow the mod wheel or pitch bend.
I'm debating which DACs to use. I have some lying around — the spoils of a time when Linear, Analog Devices, and Maxim were separate companies, and they, Microchip, and Texas Instruments would give out free samples if you had a plausible-sounding company name — but a lot of them aren't particularly well-suited for this. I want to run everything off the existing 5V supply — either a wall wart or USB — and not need elaborate external analog circuits to do things. I'm looking at the MCP4811, a single-channel 10-bit device, which has the advantage of an internal voltage reference at 2.048V, and a ×2 output, for a full range of 0V-4.096V that's very reliable even when run off a unreliable 5V power supply, like the keyboard's USB power input.
(In an ideal world, I'd have a perfect 1v reference, and a precision adder, so that the full precision of the part, all the bits, could be applied to just the 0-1V range, and then I could add single volts as needed to specify the octave. If we're calling 0V C0, then with the 10-bit setup over the 4.096V spread, you have to use value 396 to get G1, and you're imperceptibly sharp; with ten bits over a single volt, you'd use value 597 and add an extra volt and you'd be... slightly closer but flat this time. So the ideal world can fuck itself, and I'll see how the thing I actually have works.)

In the past few weeks I’ve built a model railroad signal for garden railways with a custom DCC decdoder. Here’s what it looks like:
youtube
I’ve heard from a number of people that they thought this was interesting, but they didn’t really understand what I was doing. So today I’ll try to explain the core of it all, this circuit board:

And here’s the associated circuit diagram:
I’ll try to explain why this is the way it is and what it does.
(This whole explanation is aimed at people who have never done anything with electronics before. If that’s not you, then this may be a bit boring. Also, I didn’t come up with any of the parts of this. Most of this is based on things I learned by reading OpenDCC and Mikrocontroller.net. I’m sure I still made a lot of mistakes, though, and they’re definitely all mine and not the fault of anyone on these sites.)
The goal
First let’s talk about requirements. My goal was to build an american signal type “Searchlight”. Such a signal has between one and three lamps. Thanks to a clever electromechanic design that moves different color filters around, each lamp can show different colors - up to three from a total selection of four.
Replicating this system for a model railroad is not practical. I need something else. Having multiple colored LEDs next to each other wouldn’t work; they’re too big and I want it to all look like one light source. There are LEDs that contain red, blue and green in one housing, but that would require a lot of wires quickly that all have to be put in the mast. The solution is this:

This is an “adressable” LED, better known under the name “Neopixel” used by a large american online store. There are many variations from different manufacturers. The key thing is that each LED has a tiny control circuit built right in. It takes four wires: Plus five volts, minus, data in and data out. If you have more than one, you can connect the data out of the first directly to the data in of the second and so on. Connect the plus and minus as well, and you can control almost unlimited amounts of LEDs with just three wires.
The data line has a special protocol that you need to generate. Basically you need to switch it from 0 to 5 to 0 volts again and again at a certain rate; the time it stays at 5 volts (“high”) determines whether you’re sending a 0 or a 1. From these bits you form bytes, which tell each LED what specific color value to send.
Due to this dataformat, you definitely need some electronic circuit controlling the signal, and the first requirements for this are:
Provide five volts DC power
Generate the data for the LEDs in the correct format
The Input
There are a lot of options for designing the input side of things. In my case, I’m assuming the signal is electrically connected to the rails of a model railroad that is controlled digitally. With digital command control (DCC), the voltage at the rails has a constant value of about 15 to 25 volts, larger for larger scales. This voltage constantly flips polarity; first plus is on the left rail, then it goes to the right rail (and minus vice versa), and then back. It’s like AC in normal wall outlets, but with very abrupt changes instead of a smooth sine wave.
This voltage has two tasks. First it supplies the locomotives with power, but it also transmits information. If one of these change-and-back sequences is long, it transmits a “0”; if it’s short, it transmits a “1”. These bits together then form the bytes that form the messages that say things like, “Locomotive three run at speed step 64” or “switch 10 switch to direction left”.
This decoder uses both features. The digital voltage provides both the data and the power. For a locomotive, that is required since the only conductors you have are the rails. This is a stationary decoder, so I could have designed it so that it only uses digital commands, and gets the power from an external power supply. However, I wanted to use the least amount of cables, so I’m using the simple version.
With that, the requirements are fixed. The circuit has to:
Turn the digital power (15-25 Volts, AC-ish) into 5 Volts DC
Read and understand the digital data signal (decode it, hence the name “decoder”) and calculate the colors for the LEDs.
Computation
This calculation is the real key here. The digital signal has a completely different fromat than what the LEDs expect. It’s slower, but also has completely different meaning. At best it transmits “set switch or signal 10 to state 0”. Which color values are associated with that, let alone any blending to make it look nice, are things the signal has to decide for itself. There is no way to build a simple stupid adapter here; I need a complete computer.
Luckily, you can get those for cheap and in really tiny.

The ATtiny85 costs about 1€ depending on how many you order, and it’s smaller than one cent coin (I think in basically any currency), but from a technical point of view, it is essentially a full computer. It has all the important parts anyway. There is a CPU that can run at (depending on the version) up to 20 MHz; half a kilobyte of RAM and eight kilobyte of internal storage for the program. Multiple programs is a bit of a challenge. If you know Arduinos, the ATtiny85 is related to the ATmega328p in the Arduino Uno and Nano. Far less powerful, but cheaper and significantly smaller.
What it lacks are all the surroundings like keyboard and screen for input and output. The chip is designed for applications where this isn’t needed, or at least only minimal things. The software that you write can assign each pin (okay, five out of eight) freely for different tasks: The pin can work as an input, telling the software whether there’s a low or high level of voltage at it (meaning 0 or 5 Volts), or it can work as an output and write high or low values, meaning setting the pin explicitly to 0 or 5 Volts.
There are other options for the Pins as well; among other things it can also read analog voltages and generate them to some extent. But for this task I only need the simple digital high-low inputs and outputs.
These types of chips, known as microcontrollers, exist in thousands of variations by different manufacturers with very different performance characteristics. They are the key part of basically everything that’s digitally controlled these days. Washing machines, everything that plugs into a computer including every single Apple lightning cable, TVs, TV remotes, amazing amounts of parts in cars and so on are all the realm of microcontrollers. The ATtiny85 is, as the name implies, very much at the low end of the scale (though there are smaller ones), and even here, it is a bit out of date. But it is very easy to program and very forgiving of mistakes, which makes it great in hobby situations.
To run, this chip needs around 3-5 Volts DC (some versions like the one here can also run on a bit less) and exactly one capacitor. I’m already generating 5 Volts DC for the LEDs anyway, so this chip will get them as well. That means for all the calculation, only two pieces of hardware are required.

There is some more associated hardware, though, for getting the program (which I’ve written myself) on the chip. For that you need a programmer, a device that you can buy for some money, or make yourself astonishingly easily from an Arduino. It needs to be connected with six wires to the chip. The standard for this is with a six-pin plug, which I’ve thus included here as well. There are standard six-wire cables for this.

You could connect the cables differently, for example with some sort of spring-loaded contacts on some programming circuit board you’d have to build for that, or in the worst case, just temporarily solder the cables in there. But the plug version is both simple and convenient, with the only downside that it makes the circuit a bit more pointy.
(Due to the Tumblr image limit, the next part will have to be in a reblog)

UYPP: Ben Ruel's Garage Garden
Back in March, we announced the winners for our Unleash Your Potential Program, in which six participants got to configure their own System76 computer to use for their awesome projects. This first awesome project is the Garage Garden, helmed by awesome project-er, engineer, and mighty green thumb Ben Ruel. We sat down with Ben to see how his project has been growing on the Meerkat.
Can you tell us about the Garage Garden project? What's it all about?
I spent a career with the Coast Guard and came up here—my final tour with the Coast Guard was in Juneau. Being in southeast Alaska, we’re constrained with what they call off-the-road systems, and the only way in or out of town is by boat or by plane. So all of our food comes up here by barge for a small nominal fee, or by aircraft for an incredibly large fee.
When I came up to Juneau with my wife and kids 11 years ago, we noticed that by the time our produce gets up here, it’s lived on a barge a week, two weeks out of Seattle, and you have no shelf life left on them. We started trying to grow food within the first year of getting here, and we came to the conclusion pretty quickly that with 300 days plus of rain every year, outdoor growing wasn’t really a viable option. That’s when we started a hobby farm in a garage growing some stuff in soil under fluorescent lights, as odd as that sounds.
Since then, we’ve progressed into hydroponics, but we’ve done it very manually. We go out every other day and take readings by hand, so I’ve been doing some research about building IOT devices that will talk back and automate some of the readings. My dream would be using it to actually control the concentration of nutrient solutions that we use. The overall goal is we’re going to build the hydroponic monitoring network of IOT devices, and use the Meerkat as a control center for the devices and a repository for all the data. We’ve also been doing some investigating behind the scenes into whether or not it could grow enough legs to become a business.

Is there a specific type of produce that you’re starting with?
We’ve been all over the road. Right now we’ve got lettuce. We’ve always got some kind of green leafy vegetables whether it’s any variety of lettuce that will grow hydro, some bok choy and tatsoi, and we’re growing kale like it’s going out of style. We’ve grown cucumbers to the point where I think I’ve harvested 65 pounds of cucumbers off of 4 plants over the last couple of months, but we’re really constrained by our size.
I live in a relatively small 3-bedroom house, and we’re just using a one-and-a-half car garage as our grow area. Right now I’ve got two tents. As funny as it sounds, cannabis is legal in Alaska and has been forever—my wife and I don’t touch the stuff, but because it’s been legalized, the infrastructure and the supplies that we need are freely available. We’re growing tomatoes in a tent that’s designed for marijuana growth. It works really well. It helps to maintain efficient temperature control; you can maintain temperature and humidity, block out extraneous light if you don’t want it, and cycle the lights on and off.
Depending on whether it’s too hot in the summer we’ll run the lights at night, and in the wintertime we’re looking for extra warmth, we can shift the cycle and run the lights during the day. Our big benefit up here is that, because Juneau’s all on hydroelectric power, electricity is really cheap.

What variables are being monitored?
With hydroponics, there’s a good number of parameters that you’ve got to try and keep track of. You’re basically diluting nutrients in a solution of as pure water as you can get. You want to keep track of things—your pH can’t be too acidic or too alkaline, for example.
The other big parameter is the electrical conductivity, or total dissolved solids. You want to make sure you’ve got the right concentration of nutrients, and that your nutrient solution isn’t salting up. As you’re adjusting pH back and forth, it’ll start demineralizing salt, so tracking that data gives you a good indication for when it’s time to dump the reservoir and start over.
We’re doing it manually now. I go out every couple of days and we take samples, and sit down and log it into a spreadsheet. The Meerkat acts as a control center for programming devices, keeping a repository of the programming for the IOT devices that we’re using (Arduinos with the esp8266 chips) as well as running different database programs as Docker containers, so that they can be spun up and knocked down fast enough as we try and figure out what the best way to move forward is. We’ve got a couple of database servers that I’ve been playing around with, trying to break from traditional SQL and looking at NoSQL type of databases.
I’m not an IT guy by trade. I’m more of an electronics guy, so I’m kind of doing it as a study-by-night type of project.
What has your experience been like with the Meerkat so far?
I’m actually completely blown away by the Meerkat’s performance. It’s astounding what that small form factor and footprint is able to do. I’ve used Linux for a number of years, and basically everybody’s heard of System76. I’ve seen Pop!_OS before and never really played with it all that much, but I’ve actually grown to love it. The feel, the ergonomics, the interface, and even down to the color schemes that come bone-stock right out of the box. They just make more sense to me. I’m looking forward to the COSMIC update after researching that to see how the differences in the workflow will affect things.

What software are you using for this project?
Right now we’re writing in Docker containers and running the Tick Stack from Influx. We’re also running Telegraf, Protograph, Capacitor, playing around with the Time Series Database, I’ve got a container running MongoDB I run with SQLite, and there’s a couple different IDEs I’ve got loaded on there as well for programming Arduinos or esp8266 chip flashing.
How was the setup process for the machine?
It was up and running within 10–15 minutes of pulling it out of the box. I actually took it to work, too. We do a lot of work with government agencies, and I’ve been doing a lot of microwave radio repair. I’ve got a pretty small workbench at our shop here in Juneau, so using the Meerkat to drive all of our test equipment to control the radio while logging data coming out of the radio, it was perfect. It had enough horsepower to remotely control the test equipment. I wasn’t pushing it all that hard, but setting it up and going back and forth between having it at home or at work, it was negligible to get it up and running.
Stay tuned for further updates from Ben Ruel’s Garage Garden and cool projects from our other UYPP winners!

The DIY force is strong with these 10 Arduino Star Wars projects
Hokey religions and ancient weapons might not be a match for a good blaster, but Arduino Star Wars projects certainly are. To celebrate May the 4th (also known as Star Wars Day), we’ve put together a list of inspired builds from a galaxy far, far away that you can make yourself.
So I Fixed a Broken Hasbro Lightsaber
It’s a rite of passage for every Jedi to build their own lightsaber. That goes for Arduino Jedi, too.
Alan Wang expertly upcycled a broken lightsaber toy by adding a Nano, an MP3 player module and a NeoPixel ring. The result is a Jedi weapon that’s far superior to the original toy.
youtube
Star Wars Mouse Droid with Hidden Payload
One of the first droids we meet in Star Wars is a mouse droid. The quirky little bots that zoom about the floor of the Death Star, getting under Stormtrooper’s feet.
They never actually appear to do all that much. But this zippy little droid by PotentPrintables has a hidden LED matrix that lets it deliver messages. And lots of terrible Star Wars puns, of course.
youtube
Imperial March on a Toaster
If you’re looking for sci-fi toasters, Red Dwarf is usually the first choice. But this hilarious video from Device Orchestra brings the dark side to your devices.
An Arduino controls the electromagnet in this toaster to turn it into a tuneful buzzer. Accompanied by toothbrushes and a typewriter, we get the immortal Imperial March played by droids.
youtube
Mini Arduino Star Wars Shoot ‘Em Up
A game that’s as simple as it is small and cute (like R2!), all run on a Nano on a breadboard.
And just consider how its graphics are comparable to those of the Death Star’s display as it moves into range of Yavin. Talk about human-cyborg relations!
youtube
Build a Life-Size BB8 Droid (Phone Controlled)
It was a pretty big deal when it turned out Lucasfilm built an actual droid for Star Wars Episode VII. It would have been easier to make BB8 in CGI. But we’re glad they went the practical route, as the cool ball droid has inspired a lot of makers.
Not least of them being Angelo, who built his very own amazing life-size BB8 using Arduino.
youtube
Recreating the Death Star Trench Run Scene with LEGO
As much as Wani Kim’s recreation of the iconic trench run is an incredible feat of LEGO engineering, it wouldn’t be complete without Arduino. The whole diorama is embedded with a galaxy-full of LEDs, bringing the scene to life.
That’s no moon. It’s an Arduino project!
youtube
Laser Shooting Game (Star Wars)
As Han told us, there’s no match for having a good blaster at your side. Ismail took that quite literally, and built a Star Wars laser shooting range that lets you take out those pesky Stormtroopers with a homemade blaster.
youtube
Arduino-Based Lightsaber with Light and Sound Effects
A great lightsaber build isn’t just about the colorful blade. It’s about the audio combinations, and the lighting effects when the blade makes contact. Bring all these things together, like Mad Gyver did, and you have an elegant weapon, of a more civilized age.
youtube
Prank Your Friends with Talking Darth Vader
Perfect for Halloween, as well as Star Wars Day, this motion activated Darth Vader head is just as creepy as its inspiration. It can be programmed with as many voice clips as you like, and wouldn’t it make a great option for a dark side Alexa?
youtube
Droid Build D-O
To be honest, D-O didn’t get nearly as much screen time or plot involvement as he deserved. But the latest addition to the growing line-up of Star Wars droids has been lovingly recreated by Matt Denton using a MKR WiFi 1010. No bad motivators here!
youtube
We want to hear about your Arduino Star Wars projects, so tell us all about them in the comments. May the force be with you!

What Do Player Pianos, IBM Punchcards, Telepathy and Elon Musk’s Neuralink Have In Common?
This is a player piano punch sheet or score taken from a rolled up drum. The holes make the keys move. It is a very simple pattern that translates into musical notes.
This is a decoding of “neural spikes” according to scientists at Elon Musk’s brain computer company Neuralink. The spikes are pictured in single boxes, and many spikes when they fire make a pattern. From that pattern you can begin to decode thought. According to Neuralink, “Everything you hear or think is all action potentials, its action spikes and it feels so real, it feels very real.”
This is an early IBM computer punch card, and the basic pattern recognition of the presence or absence of holes in predefined patterns led to everything we know today about computers. Though IBM introduced the first cards in 1928, they had already been in use to ‘program’ cloth in the Jacquard loom in 1804, making gorgeous silks and tapestries.
I think we are basically back in the same position as we were when IBM first made the computer punch card in 1928 in terms of brain research and decoding thought. Neuralink is putting together elements in brain research that 100 years from now, or even 50 years from now will have tremendous repercussions. The company did not invent all of the aspects of technology it is using to put things together, but they did improve upon existing tech and brought it all together.
THE SURGICAL ROBOT
The Neuralink robot doing an implantation
Neuralink works by extracting electrical signals from neurons. In order to do that it has to implant extremely thin wires in the brain to access and read those signals onto a nanochip. Before it can do that, it has to make a precision surgical robot machine operated by neuroscientists to insert the wires - so it did. Apparently there was some DARPA money thrown into the mix somewhere along the way. The robotic surgeon has to implant tiny wires in between blood vessels and neurons, not on them. This can only be achieved through microscopes and nanometer precision. The implant needle is 24 microns small. Tiny threads are about 1/10 of a human hair, which is about the same size as a neuron. The needle to implant the wire is 24 microns small. You can open the skull, insert the threads, put in a tiny chip, and then glue the skull shut. The chip functions as a wireless bluetooth signal.
THE WIRES
This picture shows thin nano threads pasted onto a fingertip. The thinness of this wire is the big issue DARPA was trying to solve with Moldavian wire from Paradromics, that I previously blogged about in 2017, but Musk beat them to the punch. He wrote about his breakthroughs here.
This is the different new design of the threads called a “linear edge”, which are made of layered polymers. They are so are super duper thin they can’t bee seen with a human eye, so they need the special robot that inserts the threads onto the surface of the brain. Another reason is the brain’s surface moves with inhalation and exhalation, and the robot can account for this natural movement. The wires and chip have to record the output from neurons. They are micro fabricated as precisely as the size of an electron beam. It is important to separate the signal to noise ratio in the chips, as they work with nanometer sizes of light. A new design. 350 nanometers,is smaller than visible light.
This image is the crux of how Neuralink acquires the signal. Here you see the neuron sending out an electrical spike and a thread next to it picking up the impulse. The electrical spike is the bulls eye. The copper colored needle is actually the implanted wire thread. You need to be 60 microns away or less to read the signals, so you really need to be under the skull. This is a graphic representation
This is a photo of the real thing, with lots of wires precision implanted into brain tissue. If you look really closely you will see they skirt around the blood vessels and neuron branches, but don’t touch any of them. Its sort of like an amazing game of darts, but the goal is to miss the bull’s eye of the vessels.
HISTORY OF IMPLANT CHIPS
This is a short history of brain research about making chips to implant in the brain. At this point the Utah array is still the most used implant chip in academia. Neuralinks chips are way, way faster and smaller. Their research builds on a century of neuroscience research and a decade of neuro engineering research. More advanced applications with advanced innovations will follow.
CHIPS AND PODS
These are early iterations of chips and devices made by Neurlink. Looks like Arduino 101, more or less.
The N1 sensor - the beginning of the sophisticated bean sized implant that goes into the skull and contains the chips.
The actual chips are made on super thin nano wafers in a hermetic environment so there is no dust. They are also super duper thin. A 4 x 4 millimeter chip has a thousand electrodes,and implanting up to 10 chips is feasible. At this point the best FDA approved chip implant for Parkinsons Disease only has 10 electrodes. The Neuralink chips read and write, and are 1000 times more powerful than what is publicly approved. They will get better with newer versions.
Shades of Cyborg Neil Harbisson and his Eyeborg! The Neuralink implant with four chips receive information from the threads, and sends them to an output area for batteries and firmware.
This is the size of the output piece, like an earphone.You can upgrade the firmware on the pod on the ear, it is not the actual implant but connects to it. It will be controlled through an iPhone app. Probably Android as well.
SIGNAL PROCESSING
Waves of neural spikes from an array from implanted threads that are being read out on a computer. monitor The color screen shows the brain at work, and traces of electrodes from single threads. Each trace is a voltage waveform in time. If you focus on one trace, it shows voltage deflections, or spikes per wave. It occurs when a neuron has an action potential, because that is the core information that is recorded. Then the algorithm is decoded, which means capturing the intended information. You just have to think about something and build up the decoding data from that information or thought, and you can begin to interpret movement, memory, and many other different types of experiences.
This is a basic diagram of signal processing from the chip - how they get the stuff out of the wires and threads to actually show the spikes. Neuralink said “Everything we care about is contained in the statistics of spikes (inside the brain).” So it goes back to the basic IBM punchcards, or the player piano drum roll - decipher the pattern and you decipher the thought.
Here is their basic logic analogue to digital conversion that is necessary to change action potential spikes to computer code..Calling Alvin Lucier, John Cage, Nam June Paik, David Rosenboom, Richard Teitelbaum - or Duh, this has been going on with the brain, changing analog to digital since 1965 in the music world.
Spike rasters in the brain - The top is the brainwave spikes pointed at by the blue arrows, and the bottom is the beginning of pattern recognition of individual neurons. There should be one pixel per electrode. They are on-chip spike detectors. The methods for detection are thresholding signals or directly characterizing the shape. The Neuralink scientists claim they can identify different neurons from same electrode based on their shape. The engineers had to modify the algorithms and scale them to compress neural data up to 200 times. It takes only 900 nano seconds to compute the signal, faster than the brain knows that the signal even occurred. They can also stimulate any combination of up to 64 channels
One good use of this in the next few years is creating visual feedback for the blind by targeting the visual cortex to create an image better than a dot matrix image - or computer vision basics meets brain wetware. The scientists want to not only read out, but read into the brain. You can read into the brain by passing a current in the electrode. This causes the cell to fire an action potential, like for cochlear implants, or a way for the eye to restore vision. You can also use this technique in the brain to restore the sense of touch or vision. The visual cortex has maps, a spatial map (orange section of the brain in graphic). If you stimulate a point in that area, a blind person sees a point of light or phosphene. The idea is you can stimulate areas of the brain in the visual cortex to resemble a dot matrix level of the world. There are also parts of the brain that control orientation, color, size and speed of moving objects, and once you figure out what they are, and where to stimulate them, you can generate a more comprehensive image that a blind person can experience. Neuralink wants a device with electrodes that are small enough, but with high density that can do better than a dot matrix image.
The first iteration of their implant will have three different types that can go from a mobile device to a mouse or keyboard on a Bluetooth signal. Neuralink needs to get FDA approval. Right now they are working on patients with complete paralysis so it is for serious neurological needs, and idea is to make it really safe.
Who needs Google maps when you can tap into someone’s brain algorithm in their Hippocampus which contains spatial orientation. Here is a rendition of someone who really knows San Francisco, and they can send you pattern signals as you wander through the park and direct you telepathically - voila!
THE PURPOSE
Musk gave a number of reasons for his very public video presentation. The first he shamelessly admitted, was to recruit for new talent to Neuralink. He then framed the motivation of his company as wanting to solve brain ailments, spinal disorders, or catastrophic injuries like a broken neck or spine,. He admitted it won’t happen quickly, and kept mentioning the need for FDA approval. He wants to make his devices as cheap and accessible as a Lasik-like device.
“Hopefully,” he said, “AI is a benign scenario. You can chose to have a neural implant if you want, it is not a mandatory thing... We already have digital super intelligence - our access to a computer and a smart phone. The input speed in the human brain is fast, due to our vision, but the output speed is slow because we have to type information into a computer. We are constrained by human bandwidth and mechanics. “
But then he dropped the Neuralink AI bomb - that he believes that we “ultimately (will) achieve a symbiosis with artificial intelligence” (if you want it at a civilization level scale). Then he added, “two people with Neuralink could have telepathy, a new kind of communication, conceptual telepathy, it has to be consensual”.
So the new “me too” movement will concern having consensual telepathy #metooconsensualtelepathy.

WEEK 5
And now let's talk about my concept.
“A panic attack is a brief episode of intense anxiety, which causes the physical sensations of fear. These can include a racing heartbeat, shortness of breath, dizziness, trembling and muscle tension. Panic attacks occur frequently and unexpectedly and are often not related to any external threat. A panic attack can last from a few minutes to half an hour. However, the physical and emotional effects of the attack may last for a few hours.
Panic attacks are common. Up to 35 per cent of the population experience a panic attack at some time in their lives. A panic attack can also be called an anxiety attack.”
https://www.betterhealth.vic.gov.au/health/conditionsandtreatments/panic-attack
A panic attack is a topic which I commenced studying. After many years of personal experience, I concluded to probably create a device that will help all of those suffering from this mental issue. Currently, most of the studies say, take a big breath or focus to your breath, seek phycologist, take phytomedicine, and the list goes further. To my experience, nothing is working.
The brain takes control of our bodies; the brain controls us. The key is to find a way to control our brain, and I know it is not so easy to achieve. Coming across, with new pieces of information about parametric design, generative design, electronics, robotics etc. throughout the studio, my personal experience and inspired by Lauren McCarthy's studies I'm about to start a concept with the title "The Slap." Yes, I know it sounds the same title as the book “The slap” by the Melburnian author Christos Tsiolkas, his topic is very dark mine is more optimistic.
My story starts years ago when I began experiencing panic attacks. The feeling of suffering a panic attack probably is the worse feeling ever; it feels like that you're dying.
Only one moment was enough to realise what can potentially treat a panic attack. The treatment is by "cheating the panic". A person experiencing a panic attack all it needs it’s an intense distraction. A slap was the moment that moved me instantly with a result to forget that I was experiencing a panic attack. So, I'm questioning myself, If I would be able to create a device that will give me this destruction. Probably yes, combining my experience and technology (Arduino technology/programming), that would be an excellent opportunity for me to study further for these technologies and to bring fun to this topic.
My ingredients are my experience, research, electronics, physical design.

Make your own chilling chambers
Or I thought of calling this post: Experiment in progress! Please do not disturb or use computer. Do not go on-line!
This is an extremely belated post, one which I have been meaning to write for more than four years (yes, I am slightly horrified). Just under a year after I arrived at UBC Rob Guy showed me a very cool chilling experiment that he had underway with undergraduate thesis student, Shannon Bell. They were interested in what temperatures actually cause chilling and were looking at a big range: -16C to +9C.
For most folks, getting enough chambers would be the tricky part of this, but Rob had helped Shannon set up a series of mini-chilling chambers as shown here. They made each ‘chamber’ out of picnic-basket sized cooler placed in a large freezer (top photo), which was then warmed to the appropriate temperature with a thermocouple controlled by an arduino system to monitor and adjust temperature (bottom photos).
It seemed like an amazing system and Rob claimed was not that hard to set up.
Shannon Bell’s thesis: Pacific northwest black cottonwood populations exhibit negative linear association between conventional chilling temperatures and bud break date. Bell & Guy. 2019
And here’s some related parts of the methods:
Small insulated environments were created using 8.5-L plastic coolers (Item #3000000166, The Coleman Company, Wichita, KS) modified to accommodate wiring and provide additional insulation. Plastic containers (Product #142-1602-4, Canadian Tire) small enough to fit inside the cooler were lined with duct insulation to shield cuttings from outside fluctuations in temperature. Small 13-watt semiconductor enclosure heaters (Omega Engineering, Norwalk, CT) were attached to a wire stand in the bottom of the cooler along with a miniature fan (Model CC 3010S12L, Chiefly Choice Co. Ltd., Taipei, Taiwan). One Type T copper-constantan thermocouple was fed through a hole in the side of the cooler and attached to the wire stand in between the fan and the heater. A second thermocouple was inserted into the cooler and placed inside the small plastic container. This container was perched on its side atop the wire stand and cushioned from the walls using foam to allow for proper circulation. Fans were connected with 12V DC power supplies. Heaters were plugged into their respective channels and voltage sources in a temperature controlling system.
Thermocouples for each treatment were attached in a floating fashion into the high and low ports of each channel on two Omega OM-USB-TC 8 Channel Thermocouple Input USB Data Acquisition Modules (Omega Engineering, Norwalk, CT) (Figure 1). One module was dedicated to the thermocouples monitoring the temperature inside the container with the cuttings. The other module monitored and controlled temperatures inside the cooler. This module had additional wires attached to the digital terminal of the module corresponding to each channel and connected to the voltage source for that channel. Wires were also attached to the ground terminals and power terminals for this module. Both Omega devices were connected via USB to a personal computer running DASYLab2016 data acquisition, control and analysis software (National Instruments, Austin, TX).
...
Coded switches were created for each channel in each Omega device in DASYLab. These switches maintained the temperature surrounding the cuttings at -16, -10, -6, -3, 0, 3, 6, and 9 °C by only sending a signal to trigger the voltage output to the heater when the temperature in the cooler fell below the value designated by the coded switch. These switch values were adjusted to account for any temperature gradients inside the cooler.
The TTL Pulse and logical operators, when used in conjunction in DASYLab, allowed for the manipulation of individual heaters while they were set to be on. To manage hysteresis brought on by the power of the heater, each channel had individual pulsing settings which caused the heater to turn on only for a set number of seconds in an interval of time while the temperature remained below the point set by the coded switch. For the 3 °C treatment, however, this pulsing mechanism was used to control the fan, since it was the only heating mechanism necessary to maintain temperature at 3 °C.

A Future Where Everything Becomes a Computer Is as Creepy as You Feared
By Farhad Manjoo, NY Times, Oct. 10, 2018
More than 40 years ago, Bill Gates and Paul Allen founded Microsoft with a vision for putting a personal computer on every desk.
No one really believed them, so few tried to stop them. Then before anyone realized it, the deed was done: Just about everyone had a Windows machine, and governments were left scrambling to figure out how to put Microsoft’s monopoly back in the bottle.
This sort of thing happens again and again in the tech industry. Audacious founders set their sights on something hilariously out of reach--Mark Zuckerberg wants to connect everyone--and the very unlikeliness of their plans insulates them from scrutiny. By the time the rest of us catch up to their effects on society, it’s often too late to do much about them.
It is happening again now. In recent years, the tech industry’s largest powers set their sights on a new target for digital conquest. They promised wild conveniences and unimaginable benefits to our health and happiness. There’s just one catch, which often goes unstated: If their novelties take off without any intervention or supervision from the government, we could be inviting a nightmarish set of security and privacy vulnerabilities into the world. And guess what. No one is really doing much to stop it.
The industry’s new goal? Not a computer on every desk nor a connection between every person, but something grander: a computer inside everything, connecting everyone.
Cars, door locks, contact lenses, clothes, toasters, refrigerators, industrial robots, fish tanks, sex toys, light bulbs, toothbrushes, motorcycle helmets--these and other everyday objects are all on the menu for getting “smart.” Hundreds of small start-ups are taking part in this trend--known by the marketing catchphrase “the internet of things”--but like everything else in tech, the movement is led by giants, among them Amazon, Apple and Samsung.
For instance, Amazon last month showed off a microwave powered by Alexa, its voice assistant. Amazon will sell the microwave for $60, but it is also selling the chip that gives the device its smarts to other manufacturers, making Alexa connectivity a just-add-water proposition for a wide variety of home appliances, like fans and toasters and coffee makers. And this week, both Facebook and Google unveiled their own home “hub” devices that let you watch videos and perform other digital tricks by voice.
You might dismiss many of these innovations as pretty goofy and doomed to failure. But everything big in tech starts out looking silly, and statistics show the internet of things is growing quickly. It is wiser, then, to imagine the worst--that the digitization of just about everything is not just possible but likely, and that now is the time to be freaking out about the dangers.
“I’m not pessimistic generally, but it’s really hard not to be,” said Bruce Schneier, a security consultant who explores the threats posed by the internet of things in a new book, “Click Here to Kill Everybody.”
Mr. Schneier argues that the economic and technical incentives of the internet-of-things industry do not align with security and privacy for society generally. Putting a computer in everything turns the whole world into a computer security threat--and the hacks and bugs uncovered in just the last few weeks at Facebook and Google illustrate how difficult digital security is even for the biggest tech companies. In a roboticized world, hacks would not just affect your data but could endanger your property, your life and even national security.
Mr. Schneier says only government intervention can save us from such emerging calamities. He calls for reimagining the regulatory regime surrounding digital security in the same way the federal government altered its national security apparatus after the Sept. 11, 2001, attacks. Among other ideas, he outlines the need for a new federal agency, the National Cyber Office, which he imagines researching, advising and coordinating a response to threats posed by an everything-internet.
“I can think of no industry in the past 100 years that has improved its safety and security without being compelled to do so by government,” he wrote. But he conceded that government intervention seems unlikely at best. “In our government-can’t-do-anything-ever society, I don’t see any reining in of the corporate trends,” he said.
Those trends are now obvious. It used to be difficult to add internet connectivity to home devices, but in the last few years the cost and complexity of doing so have plummeted. Today, off-the-shelf minicomputers like the Arduino can be used to turn just about any household object “smart.” Systems like the one Amazon is offering promise to accelerate the development of internet-of-things devices even further.
At a press event last month, an Amazon engineer showed how easily a maker of household fans could create a “smart” fan using Amazon’s chip, known as the Alexa Connect Kit. The kit, which Amazon is testing with some manufacturers, would simply be plugged into the fan’s control unit during assembly. The manufacturer also has to write a few lines of code--in the example of the fan, the Amazon engineer needed just a half-page of code.
And that’s it. The fan’s digital bits (including security and cloud storage) are all handled by Amazon. If you buy it from Amazon, the fan will automatically connect with your home network and start obeying commands issued to your Alexa. Just plug it in.
This system illustrates Mr. Schneier’s larger argument, which is that the cost of adding computers to objects will get so small that it will make sense for manufacturers to connect every type of device to the internet.
Sometimes, smarts will lead to conveniences--you can yell at your microwave to reheat your lunch from across the room. Sometimes it will lead to revenue opportunities--Amazon’s microwave will reorder popcorn for you when you’re running low. Sometimes smarts are used for surveillance and marketing, like the crop of smart TVs that track what you watch for serving up ads.
Even if the benefits are tiny, they create a certain market logic; at some point not long from now, devices that don’t connect to the internet will be rarer than ones that do.
The trouble, though, is that business models for these device don’t often allow for the kind of continuing security maintenance that we are used to with more traditional computing devices. Apple has an incentive to keep writing security updates to keep your iPhone secure; it does so because iPhones sell for a lot of money, and Apple’s brand depends on keeping you safe from digital terrors.
But manufacturers of low-margin home appliances have little such expertise, and less incentive. That’s why the internet of things has so far been synonymous with terrible security--why the F.B.I. had to warn parents last year about the dangers of “smart toys,” and why Dan Coats, the director of national intelligence, has identified smart devices as a growing threat to national security.
Connecting everything could bring vast benefits to society. But the menace could be just as vast. Why not go slowly into the uncertain future?

Best Torrent Client Raspberry
The Raspberry Pi is an awesome little computer, whose capabilities won’t stop increasing. As such, you should make sure that you have the best apps installed on it. Whether you’re running Raspberry Pi OS (formerly known as Raspbian) some apps are unmissable.
Best Torrent Client Raspberry Pi

TORRENTS comment = Torrents path = /mnt/torrents create mask = 0755 directory mask = 0755 read only = no browseable = yes public = yes force user = pi only guest = no” To save this file, press Ctrl X then Y then Enter. Now we need to reboot the Raspberry Pi once again. NOTE: If it doesn’t works, try installing samba and doing. QBittorrent is one of the best torrent clients available that runs on the Raspberry Pi's ARM hardware. It sports both a desktop client and an easy to use web interface. One of the best parts of qBittorrent is its powerful web interface that allows you to control almost every aspect of the client with relative ease. Next, download a popular torrent client - dedicated Torrent box for the torrent admin Step Four: Test — I would like a torrent server over 4 Model B (for setup a new headless, Note Other VPN services a straightforward method for active account with AirVPN. To Raspberry pi deluge on the Pi too drive. An active account better ethernet).
Here are best apps for your Raspberry Pi.
Doesn’t Raspberry Pi Come With Apps Preinstalled?
Before proceeding you’re probably thinking “hold on, my copy of Raspberry Pi OS already has a bunch of apps installed.” No doubt you’re thinking of VLC media player, Scratch, and LibreOffice.
Best Torrent Client Raspberry Pi
With three editions of Raspberry Pi OS to choose from, though, you won’t be surprised to find that those apps aren’t included on them all. The Lite version comes with little to talk of, not even a desktop, and is aimed at project builders. Meanwhile the “Raspberry Pi OS with desktop” comes with VLC media player and the Chromium Web Browser, but little else.
The “Raspberry Pi desktop and recommended software” version, meanwhile, is jam-packed full of everything you could need. But it’s a bit of a big download, so you might prefer to avoid it.
Whatever the case, we’ve chosen the best 10 Raspberry Pi apps that you don’t already have installed. Let’s take a look at them.
So, add VLC media player and Scratch as required
1. Guake
Whether you’re new to Linux or an expert, the default Terminal is frustrating. It’s plain, obscures the desktop, and, overall, the Terminal application is difficult to appreciate.
Best Torrent Client Raspberry Pi
Consider a replacement: Guake. With a Quake-style semi-transparent interface, Guake can be installed via the Add/Remove Software tool.
After installation, you’ll find it in Applications > System Tools > Guake. Once you see the notification that Guake is running, tap F12 to summon it. Guake will drop down from the top of the screen when called.
Guake lets you see what is happening elsewhere on the desktop. You can also right-click inside the Guake window to alter the Preferences, which includes tweaking the appearance.
2. Synaptic Package Manager
It’s easy enough to install software via the command line, and Raspbian has its own mouse driven Add/Remove Software tool. But sometimes that’s not enough. If you’re looking for something more expansive, try Synaptic.
Unlike the native tool, Synaptic uses more specific software categories, helping you to find the tools you need. Synaptic (one of several Linux package managers) also ensures you’re using the current version of apps installed on your Pi. All you need to do is click Reload and then Apply to run the updates.
You can install Synaptic Package Manager on Raspbian with:
Once installed, run it with a command:
…or launch Synaptic Package Manager from the Preferences section of the desktop menu.
3. MyPaint
Best open source apps lists like this almost always suggest GIMP as a sort of easy Photoshop alternative. While this is a good option, it’s often preinstalled on Raspberry Pi OS. For something a little different, try MyPaint.
This is an open source graphics editor for digital painting, rather than image manipulation. Closer to Corel Painter or Krita than Photoshop, it includes layers, brush settings, scratch pad, and brushstrokes that differ based on the angle and zoom. Many other features can be found on the project’s GitHub page.

To install MyPaint, open a terminal and enter
Alternatively, find it in Add/Remove Software in the Graphics category.
4. QMMP
VLC media player plays music, but if you’re looking for something a more visually striking, try QMMP.
With support for all the usual audio formats (MP3, FLAC, Ogg FLAC, Ogg Vorbis, WAV, CD Audio, etc.), it also delivers equalization settings and visual effects.
Various plugins are also supported, adding functionality. This ranges from playing music from YouTube to playing chiptunes (music created on or for 8-bit systems).
Install QMMP with
You’ll also find it in Add/Remove Software listed under Multimedia. Once installed, simply launch it from Menu > Sound & Video and open your favorite tunes.
5. DOSBox
The Raspberry Pi isn’t exactly short of games. Amateur developers and have created hundreds of homebrew games; some Linux titles run on the Pi, too. It’s also an excellent platform for playing retro games.
Various types of emulation are possible with the Raspberry Pi, from 8-bit home computers to consoles. But if your preference is for classic PC games, try DOSBox.
Capable of running all software from the MS-DOS era, DOSBox lets you play PC games from the 1980s and 1990s.
To install DOSBox on the Raspberry Pi, open Preferences > Add/Remove Software and search for it. Once installed, head to your Home directory and create a new folder, dosgames. This is where you should save the extracted contents of downloaded games to, ready to use them.
DOSBox itself can be launched from Menu > Applications > Games > DOSBox Emulator. See our guide to using DOSBox for help on configuring the application and finding and installing games.
6. Arduino IDE
Planning to pair your Raspberry Pi up with an Arduino for some maker fun? If so, you’ll need Arduino IDE (Integrated Development Environment). The IDE makes it simple to write and upload code to any Arduino connected to your Raspberry Pi.
You can install Arduino IDE on your Pi via Preferences > Add/Remove Software.
Once installed, launch via Applications > Programming > Arduino IDE. Use the Tools > Boards menu to select the correct Arduino model (Arduino Uno and clones are selected by default).
From here, you can check File > Examples for some useful example scripts for the Arduino. You can also extend its capabilities via new libraries. You’ll find information on these at www.arduino.cc/en/Reference/Libraries. Meanwhile, our detailed guide to Arduino will help you get started.
7. NixNote
Using a different computer doesn’t mean you won’t need to keep notes from time to time. NixNote is an open source client for Evernote, easily installed in Add/Remove Software.
Once installed, NixNote gives you access to your existing Evernote archive of ideas, jottings, lists, and so on. It can export as PDF, and the data can be backed up and restored as needed.
In short, this is a useful notebook client that syncs with Evernote on your other devices for unified notetaking.
8. Deluge
First things first: Deluge is a BitTorrent client. This doesn’t mean that it is illegal; BitTorrent itself isn’t illegal. Rather, the misuse of the peer-to-peer networking technology to download copyright-protected movies and games is illegal.
For instance, many Linux operating systems (including Raspbian) can be downloaded over BitTorrent. This provision reduces the overhead on hosting the distribution on a dedicated server. Our guide to BitTorrent explains this in more detail.
Best Torrent Client Raspberry Pi
Why might you need a BitTorrent client on your Raspberry Pi? Well, it depends how you’re using the computer. If you utilize it as a repository for personal data, Deluge can download data from your Pi wherever you are. Full details on how to this can be found on the Deluge Wiki.
You’ll find Deluge in Preferences > Add/Remove Software. If you want to use the torrent app in headless mode, connect via SSH and run:
Once this is done, Deluge is ready to run. Pi desktop users can launch it in Menu > Internet.
9. OpenVPN
Every computer should connect to the internet via a VPN. While there are no VPN clients for the Raspberry Pi, there is OpenVPN.
This is a VPN client app that lets you connect to your preferred VPN server using existing account credentials. For example, you can connect to ExpressVPN VPN servers using the configuration files they provide.
Install OpenVPN with
Be sure to download the OVPN configuration file for your preferred server and save it on your Pi. Most VPN services provide OpenVPN support so this should be straightforward.
Check our guide to setting up a VPN on the Raspberry Pi for configuration tips.
10. Steam Link
While the Raspberry Pi doesn’t have the hardware to run standard PC games, it is good enough to stream them. This is possible thanks to the Steam Link software from Valve, which lets you stream games from a PC.
With the games you want to play installed on your PC and streaming enabled, setup is simple. Just connect your Raspberry Pi to your TV and run
Learn more in our guide to Steam Link for Raspberry Pi.
Awesome Raspberry Pi Apps You Can Install Today
Along with the apps already installed on your Raspberry Pi, a wealth of alternatives is available. They bring new functionality, improve privacy, deliver gaming, improve productivity, and more.
Which apps you install will determine how you use your Raspberry Pi. Explore the possibilities further in our guide to the best Raspberry Pi projects.

RPi consumes only a few watts of power so it seems to be ideal torrent client platform – it can run for days and slowly (or not) download the content from internet. Setting up Torrent client is very easy. Here is how to do it…
We will install torrent client called Transmission. Before we do that lets update and upgrade our packages.
2
sudo apt-getupgrade
Installing the client:
After installation we need to configure it a bit, but don’t worry, it will take only a few minutes. Configuration file is /etc/transmisson-daemon/transmission.json. There are several values we need to change – here is the list of modified parameters (we will be modifying the rest but in more human way later on). Before editing the config file stop daemon (if you stop daemon after editing the file, your changes will be overwritten):
To update config file execute:
First we’ll get rid of authentication when connecting to Transmission using web browser
'rpc-authentication-required': false
To avoid loosing any control over who connects to our Transmission we can define IP address range of computers that can connect. With the below settings, Transmission will be controlled by computers with IP addresses starting with 192.168.1.* and from local host (RPi).
'rpc-whitelist': '127.0.0.1,192.168.1.*'
Also make sure that the following parameters are set in this way:
'rpc-port': 9091 'rpc-url': '/transmission/'
Now, start Transmission-daemon:
From computer/tablet that has ip within the defined (above) range, connect to your Transmission: (assuming IP of your Raspberry Pi is 192.168.1.106)
192.168.1.106:9091 or 192.168.1.106:9091/transmission (no / at the end of url) or 192.168.1.106:9091/transmission/web/ (remember about / at the end of the address)
If you did everything right here is what you should see:
Now, with graphical interface you can easily set majority of Transmission properties as well as upload torrent files and start downloading. The setting you do in web interface will be reflected in settings.json file as soon as Transmission is stopped. If you still want to modify properties in config file, here is a link to description of all possible settings Config File Parameters Description
Remember, that when you set directory for downloaded files, this directory needs to have right privs so that Transmission would be able to write files there. If it’s external drive that will host the directory (most likely that will be the case) and you’ve installed Transmission on RaspBMC, mount if with mode=000 setting in fstab as described in DLNA installation.
Is it over? It can be if you’re fine with checking the download status from web browser, but it would be much cooler to be able to monitor, start and stop torrents from XBMC, since most likely you would like to use XBMC to view/listen media (if you’re downloading one). There is XBMC plug-in that you can install from XBMC GUI. To install go to: System->Settings->Add-ons->Get Add-ons->XBMC.org Add-ons->Program Add-ons->Transmission and select install. If you disabled logging to Transmission there is nothing to configure. If you enabled it you need to enter username and password in the settings.
To start the plugin go to: Programs->Transmission
Transmission daemon XBMC plugin
Transmission daemon XBMC plugin – detailed torrent status
Isn’t that cool? :)
