Solenoids go clicky-clacky 🔩🔊🤖

We're testing out an I2C-to-solenoid driver today. It uses an MCP23017 expander. We like this particular chip for this usage because it has push-pull outputs, making it ideal for driving our N-channel FETs and flyback diodes. The A port connects to the 8 drivers, while the B port remains available for other GPIO purposes. For this demo, whenever we 'touch' a pin on port B to ground, the corresponding solenoid triggers provide an easy way to check speed and power usage.

I know this take has been done a million times, but like…computing and electronics are really, truly, unquestionably, real-life magic.

Electricity itself is an energy field that we manipulate to suit our needs, provided by universal forces that until relatively recently were far beyond our understanding. In many ways it still is.

The fact that this universal force can be translated into heat or motion, and that we've found ways to manipulate these things, is already astonishing. But it gets more arcane.

LEDs work by creating a differential in electron energy levels between—checks notes—ah, yes, SUPER SPECIFIC CRYSTALS. Different types of crystals put off different wavelengths and amounts of light. Hell, blue LEDs weren't even commercially viable until the 90's because of how specific and finicky the methods and materials required were to use. So to summarize: LEDs are a contained Light spell that works by running this universal energy through crystals in a specific way.

Then we get to computers. which are miraculous for a number of reasons. But I'd like to draw your attention specifically to what the silicon die of a microprocessor looks like:

Are you seeing what I'm seeing? Let me share some things I feel are kinda similar looking:

We're putting magic inscriptions in stone to provide very specific channels for this world energy to flow through. We then communicate into these stones using arcane "programming" languages as a means of making them think, communicate, and store information for us.

We have robots, automatons, using this energy as a means of rudimentarily understanding the world and interacting with it. We're moving earth and creating automatons, having them perform everything from manufacturing (often of other magic items) to warfare.

And we've found ways to manipulate this "electrical" energy field to transmit power through the "photonic" field. I already mentioned LEDs, but now I'm talking radio waves, long-distance communication warping and generating invisible light to send messages to each other. This is just straight-up telepathy, only using magic items instead of our brains.

And lasers. Fucking lasers. We know how to harness these same two energies to create directed energy beams powerful enough to slice through materials without so much as touching them.

We're using crystals, magic inscriptions, and languages only understood by a select few, all interfacing with a universal field of energy that we harness through alchemical means.

Electricity is magic. Computation is wizardry. Come delve into the arcane with me.

Thinking further about the SilverLink, given that it's demonstrably possible to upload any damn firmware you want onto the 24LC64 EEPROM, I bet I could do an evolution of the i68 project where the key matrix state->keypress event translation occurs inside a hacked cable -- y'know, by having it present as an HID keyboard and such. That could be a fun project.

Hi, I just got into tech (actually 1 year in but I still feel like I don't know anything).

I learnt python, R, SQL, Tableau and concepts in Data Structures, Algorithms.

[Just the Basic level of the listed.]

But I can't write my own programs on python or create anything.

I was hella impressed by your microprocessor project, and when I took up tech (ai and data science) I assumed I would do something like that or at least code.

Now, I am just venting but where do I start, how do I make projects what are some interesting projects, what should I learn? A lot of my seniors tell me to have a wide range of knowledge like focus on one thing by depth but add other things. For example: you can study data analytics in depth but have some knowledge in ethical hacking and web development etc. Like an all rounder.

Wow ok a lot to unpack here, I'll get started

Lots of places recommend that you start with Arduino, as there are a lot of good tutorials out there. I somewhat disagree

I think that raspberry pi is better because it's usually a lot cheaper to buy the stuff you want to play around with

But an even cooler way to do it, go to wokwi.com and start a project on a Raspberry Pi Pico (make sure it's the micropython version) and then you can get started there

Google something like "Blink led with Pi Pico micropython" and there will be a tutorial or two

Then, once you've played around for a while you can buy a Pi Pico for very little money and see your stuff work irl!

If you need any more help or have any questions, feel free to DM me and I'll see what I can do

Prototype time!

My first project in 2025. It was nice trip down memory lane, returning to 8bit micro controller. I am still trying to get the hang of the printing setup and new filament so the printing is pretty poor on this one.

[deanpinterester]

slowly putting together my plan to make a much much improved momo costume (i even have a spreadsheet and everything!!) but the amount of new things i'd have to buy is kind of scary tbh

[kandiyaki]

active low inputs and outputs should be illegal. if theres a 1 that means 1 thing is on. i dont care how much easier it is to manufacture. if i press my button the thing should go up

I created an Arduino themed Fursona. Her name is UNO!

FruitJam 10 PRINT CHR$(205.5+RND(1)); : GOTO 10 🎮🕹️💾🍊

We're working on getting some fun emulators ported to the FruitJam

. Of course, we wanted to start with the C64, so when we found the MCUME

emulator project with many retro machines already done and ported to popular microcontrollers, we got right to checking it out! Here, Jepler is testing out the C64 with video output on HSTX. Next up is the keyboard, but for now, it's fun to test out the famous 10 print… goto 10 script

and watch the vibes generate.
