Lab 5: Arduino and P5.js :)

The objective of this lab was to establish serial communication between an Arduino and a P5.js sketch using the P5.SerialControl library. The goal was to read analog input from a potentiometer (or other sensor) and use this data to manipulate a sound parameter in P5.js. This experiment introduces the concept of serial communication and demonstrates how real-world input can create interactive experiences in a digital environment. The materials used were Arduino Uno Hardware , Breadboard, Jumper wires, Potentiometer (10kΩ) Arduino IDE software & P5.js web editor and installed P5.SerialControl library for P5.js (Darwin version).

Descriptive Circuit Overview:

As said above, the circuit consisted of an Arduino Uno, a 10kΩ potentiometer, and a serial connection to a P5.js sketch. The potentiometer is wired with:

The Potentiometer placed in the middle of the bread board.

Ground and power wires connected across the bottom edge of the breadboard.

The middle pin connected to A1 (analog input pin on the Arduino).

One outer pin connected to 5V power in the Arduino.

The other outer pin connected to ground (GND) in the Arduino.

This setup allows the potentiometer to function as a voltage divider. When the potentiometer is turned, the resistance changes, changing the voltage received by the Arduino’s analog input pin. The Arduino was able to read this voltage using the analogRead() command, converted it into a numerical value (range: 0 to 1023), and sent this data to the P5.js sketch over the serial communicator (P5.js Serial.Control).

Schematic:

Code Explanation Overview-Arduino:

The Arduino code initializes one analog pin, A1, to read input from the potentiometer. The values are then sent via the Serial.print() function in a comma-separated format, allowing P5.js to parse them correctly.

Pin Setup: The potentiometer’s pin is set as an input using pinMode(sensorPin, INPUT).

Analog Reading: The values A1 are continuously read using analogRead(sensorPin).

Serial Communication: The values are sent over the serial port using Serial.println(sensorValue);. The comma serves as a delimiter to separate multiple values.

This ensures that the final P5.js sketch can properly interpret and map the incoming data, which would be displayed in the serial console/monitor of the Arduino Uno, Serial Controller, and P5.js web editor console. In other words, the serial controller allows the code to be communicated from the Arduino software to the P5.js. The code is below:

int sensorValue = 0;

int sensorPin = A1;

void setup() {

// put your setup code here, to run once:

pinMode(sensorPin, INPUT);

Serial.begin(9600);

}

void loop() {

// put your main code here, to run repeatedly:

sensorValue = analogRead(sensorPin);

Serial.println(sensorValue);

}

Code Explanation Overview-P5.js:

The P5.js sketch establishes serial communication with the Arduino and reads the sensor data to control a visual representation through the resistance of the potentiometer.

Serial Communication Setup: The script initializes a serial connection using serial = new p5.SerialPort();, lists available ports, and attempts to open the correct one.

Data Reception: The function serial.on('data', gotData); listens for incoming serial data and stores it in a variable.

Data to Visuals: The sensor values are used to control the size of a circle on the canvas (circle(20,20,latestData);) in function draw().

Display of Values: The latest received data is displayed on the screen using text(latestData, 10, 10).

The code is below:

let serial; let latestData = "waiting for data";

function setup() { createCanvas(windowWidth, windowHeight);

serial = new p5.SerialPort();

serial.list(); serial.open('/dev/tty.usbmodem1301');

serial.on('connected', serverConnected);

serial.on('list', gotList);

serial.on('data', gotData);

serial.on('error', gotError);

serial.on('open', gotOpen);

serial.on('close', gotClose); }

function serverConnected() { print("Connected to Server"); }

function gotList(thelist) { print("List of Serial Ports:");

for (let i = 0; i < thelist.length; i++) { print(i + " " + thelist[i]); } }

function gotOpen() { print("Serial Port is Open"); }

function gotClose(){ print("Serial Port is Closed"); latestData = "Serial Port is Closed"; }

function gotError(theerror) { print(theerror); }

function gotData() { let currentString = serial.readLine(); trim(currentString); if (!currentString) return; console.log(currentString); latestData = currentString;

}

function draw() { background(255,255,latestData); fill(0,0,0); text(latestData, 10, 10);

fill(5,200,5); circle (20, 20 latestData);

// Polling method /* if (serial.available() > 0) { let data = serial.read(); ellipse(50,50,data,data); } */ }

Lastly, into the P5.js helm library file of the sketch, we put this P5.js Port Control Script link library in it as well:

<script language="javascript" type="text/javascript" src="https://cdn.jsdelivr.net/npm/p5.serialserver@0.0.28/lib/p5.serialport.js"></script>

Observations/Analysis:

When manipulating the potentiometer, the values ranged from 0 to 1023 (Arduino’s 10-bit ADC resolution). These values were mapped in P5.js to control the size of the circle in real-time, and went further to change the background color as well. The movement of the shape corresponded smoothly to changes in sensor input, proving the effectiveness of serial communication.

If we had applied the data to sound manipulation, the potentiometer’s values could have been mapped to control frequency, volume, or panning. The map() function would be used to scale the 0-1023 range into an appropriate audio parameter range in P5.js.

A demo video of the outcome is below:

Challenges and Troubleshooting:

Some challenges encountered included:

Serial Port Connection Issues: Initially, P5.js could not detect the correct serial port. This was resolved by having manually specifying the port (serial.open('/dev/tty.usbmodem1301');) in the script. This required a lot of troubleshooting code and hardware at first.

Conclusion:

This lab demonstrated how Arduino and P5.js can communicate through serial data, allowing physical input to control digital outputs. The way. that the potentiometer was able to change the size of the circle, isthe same way it can be used to turn vilume up and down on a device. Understanding serial communication opens up possibilities for interactive installations, such as motion-sensitive visuals or audio-controlled audio experiences. This aspect introduces new ways to map sensor input to audio-visual feedback, an essential skill in creative coding and physical computing.

In the future, this technique could be expanded by integrating multiple sensors and including the synthesis of sound assets to creat an immersive experience.

...Or it could be used in part to make a DIY iPod.

Further development on my Glitch Storm (check that tag for earlier posts). I've become rather fond of listening to the thing as I do other tasks, but it was a little unwieldy for that purpose — it had to be powered by USB, it was all sharp edges and exposed wires, and plugging in headphones required a Rube-Goldbergian series of adapters — first an inline potentiometer to lower the volume to tolerable levels, and then a mono-to-stereo converter so it didn't just drone in the left ear — so I've been upgrading.

The panels it's sandwiched between are 1.5mm thick styrene, purchased at the local hobby shop — they're often used for making buildings for architectural renderings or model railroad layouts. The cuts are a little haphazard — it fits the "glitch" aesthetic, but it's mostly due to not having worked with the stuff before. They're held on by 4-40 screws, under the black screw caps, which are held away from the board by homemade spacers made by cutting aluminum tubing. I do have better drawings of where all the mounting holes are, so a future version of these plates is in the offing.

I was using USB battery packs for a bit, but that gets cumbersome, so yesterday I mounted an on/off switch on the top panel which allows power from a 9v battery to flow in. I need a better mounting solution for the battery than "just holding it", but that'll come.

Finally, today I built a plug-in, all in one headphone adapter — it's a mono plug soldered onto a fader, which is then attached to a stereo jack. I don't have a photo of that — it's right now curing from being partially encased in room-temperature vulcanizing rubber to insulate the connections. That'll reduce the thing down to a single unit, rather than the object itself, two adapters strung on short extension cables, and an outboard battery pack.

(Why a headphone adapter and not just build in a volume knob and use a stereo jack? I still need to plug it into mono stuff — remember, I had to disable stereo output because plugging in a mono plug would short out the output — and without any attenuation, it's at the right level to drive my Eurorack-compatible stuff, so I can have my synth filters and such play with the output. So this way, I can have both worlds.)

SEMA is a hard show at which to properly appreciate cars. On one hand – it’s a show overflowing with some of the best builds you will see all year. On the other hand – it’s that same overflow that makes it almost impossible to keep your wits about you. It’s almost too much of a good thing. In a sea of thousands of cars, I feel like some inevitably get lost. The great thing is: The cars that are truly memorable, the cars you are talking about weeks and months after the show… are cars which rise above the temporary flash-in-the-pan Instagram fame. Some cars deserve to be immortalized. More than digital noise or passing fancy, they draw their inspiration from the timeless. The classic. 

  This 240Z certainly qualifies as one of these cars. While it has some innovations and forward thinking design elements, it also honors the tradition and legacy of Datsun’s Z car heritage. Car owner Dennis wanted a Z that could be as menacing on the street as it was on the track. In looking to manifest his dreams into reality, he was fortunate enough to meet aspiring builder Kyle Kuhnhausen. Kyle is a fresh out of business school automotive entrepreneur with a penchant for metal work. Ok, more than a penchant… he has a gift.  From the paint scheme to the heavily gusseted cage, this car is well thought out & beautifully executed. How well executed? Well, when we talked he made sure I knew that the LS swap was a place holder engine until they built something truly epic for under the hood. WOW. Some place holder. 

Let’s take a moment and revel in my three favorite aspects of this car. 

  First) 

There is the paint scheme. Nimbus Grey (or battle ship grey in some parlance) has to be my personal favorite hue on show cars. It’s rich, it allows shadows to adopt a deep dark over tone, and light reflections to be silvery & pronounced. Every truly beautiful design looks amazing in this color. So… win number one? CHECK! The Peter Brock homage striping is as evocative and respectful of the Z’s motorsport heritage as it is a tasteful modern touch of racer bravado. I dig it. Those famous side stripes actually start on the hood at the vents and then cascade over the fender and down the side forming the Brock stripes we are all familiar with. A killer design cue that is at once forward thinking and period correct. Nicely done. 

Second) 

Let’s talk about that metal work. The Aero is mean, functional, and gives the car a seriously provocative stance. What’s more – it’s designed to just rip/break away cleanly in the case of a momentary lapse in driver skill (for example paying a visit to say, China Beach at the end of the straight at Mid Ohio). Well played Kyle, well played. However, as fantastic as that aero is, it is nothing compared to the beautifully executed roll cage. Meant to be a street car that can participate is serious track time… it had to be a car from which Dennis could easily get in and out. Kyle kept the safety high by fabricating one seriously artful, yet stout, fully gusseted integrated cage. Take a few moments and look at the cage in this car. I have severe race car envy. My race car has race car envy. Seriously. It is so good that it easily merits adjectives like superlative, excellent, exemplary. Bravo. 

Third) 

And this is one where so many cars sort of take a pass… the gauge cluster. When a car has track day toy duties, it’s easy to just pick up a digital display, mount it up, and just call it done. Not in this car. The cluster in this car is 13 individual pieces of aluminum lovingly hand shaped into what you see before you. It honestly called to mind some of the extreme and bespoke modern interpretations currently en vogue built around the Porsche 911. The Singer cars being the most notable, they take an air cooled 911 and massage every aspect of the car… and polish, preen, & refine it until it is absolutely jewel-like. The perfect 911. Well, that’s where this Z took me. It’s like a really nice 240Z… only polished to the highest possible degree. Everywhere you look there are tasteful touches. This instrument cluster exemplifies that. The angle at which it is canted toward the driver, the alignment of it inside the MOMO wheel. It’s absolutely glorious. 

So yeah, this car is one of the highlights of last year’s SEMA show. It truly was. Bespoke modern takes on past classics are hot right now. Cars like the Singer 911s are fetching 500k and more per unit, so it makes builds like this kind of a serious proposition. Get it right and the value and classic status is legitimate. In the end, Dennis can drive this car on the road or the track, confident in the fact that he found the perfect enthusiast to execute his vision. And he can rest well in the fact that he’s now driving the Singer of Datsun 240Zs.

Advantages Of Using Potentiometers For Motor Speed Control

Motors and machinery in your tools must be able to be controlled at the correct speed if you want them to operate efficiently. If you allow yourself full-speed control, there will be little to no tool chatter and, every time, a flawless machined finish. You may choose the ideal cutting speed for every machining task and maintain your machine's operation at this speed to achieve the best results with full-speed controls. The generator output frequency can be precisely set by adjusting the engine speed with a motor speed potentiometer.                      Potentiometers come in a variety of varieties and are currently sold on the market. Potentiometers can be divided into two categories: linear and rotational. Motorized potentiometers are used in a range of industrial automation and process control applications, such as speed controls, flow meters, tensioning motors, etc., by providing automatic remote control and using a human control knob. A mechanical potentiometer has been converted into a potentiometer motor control. These devices are simple to install, operate, and maintain. They can be used with synchronizing or load-sharing units as well as supplying speed reference to any electronic regulator or AVR controller. An essential component of many different forms of machinery. These gadgets operate without a power source or additional circuits because they are passive gadgets. They enable precise voltage measurement and the transformation of fixed voltage into variable voltage. Potentiometer applications include managing audio equipment's loudness and measuring the position of a gaming joystick. These instruments do, however, have a significant impact on the marine industry. Advantages of potentiometer

1. Potentiometer works on the zero deflection method, so the possibility of error is very slight. 

2. The standardization of potentiometers can be achieved directly by using a standard cell. 

3. It is possible to increase the length of the potentiometer wire for a greater degree of accuracy.

4. This device does not draw current from the circuit that it is placed in. Along with the motor speed potentiometer, there is various marine equipment like protection relays, high-speed engine controllers, flexgen power systems, and more. These all make marine operations comfortable and easy. If you are searching for this kind of tool or equipment, Selco USA brings you a range of quality marine equipment.

High torque servo motor arduino

#High torque servo motor arduino manual#

#High torque servo motor arduino full#

Similar to the Sweep sketch, the servo motor signal pin is attached to pin 9 of the Arduino UNO. On the Arduino IDE, go to File > Examples > Servo > Sweep. This library comes with the IDE so no additional downloads necessary. The Arduino Servo library has two easy-to-use examples. By the way, there are other ways to generate PWM besides the hardware PWM on the Arduino. Side note: But it doesn’t mean that the control pin is limited to only a PWM pin. This means this lead must be connected to any of the pins with the ~ in them. The yellow pin is where you would send PWM signals to the Arduino. Remember that the Arduino +5v pin is limited to 500 mA! Thus, the number (and sometimes, type) of servos you can use is limited. My MG996R draws 10 mA at idle, 170 mA when operating but without any load connected and stalls at 1400 mA (!). However, larger servos might draw more current which can reset the Arduino. Most servo motors run on 5V so you can attach the red lead to the Arduino’s +5V pin. Servo motors that don’t produce high torque typically contain plastic gears.Ī better look at the circuit board, dc motor and potentiometer: This servo motor is capable of producing high torque (rotational force), and thus has metal gears inside: Other servo motor brands have different colors for their wires but almost all uses red for +5V and black for ground. Servo Motor InternalsĪs you can see, there are three wires: red for +5V, black for ground and yellow for pulse. There is a way to make a continuous rotation servo and is shown in this tutorial. A continuous rotation servo is stronger than a an ordinary dc motor. The limited possible values for PWM signals needs to be mapped to a smaller range (of angles).

#High torque servo motor arduino full#

Originally designed for converting rotational motion to linear motion, servo motors do not need full 360 degree rotation (see crank mechanism).

There are two reasons why servo motors don’t rotate for a full circle: There is mechanical stop at the gear assembly to limit the rotation of servo motors to 180 degrees. If you want to get the exact pulse width for a specific angle, you must test your servo motor. The exact pulse width could vary per servo motor. The position of the servo motor arm corresponds with the width of the pulse: From SM2608 Hardware Hacking Workshop Also, the gears boost the torque output of the servo motor. The gear assembly slows down the rotation of the motor to a speed that the potentiometer can catch up.

The potentiometer (via voltage divider) generates a voltage equivalent to that of the input pulse that stops the DC motor, indicating equilibrium.

As the motor turns, the gear assembly turns and thus also turns the potentiometer.

When a pulse is applied, the two inputs on the error amplifier is no longer equal and thus the amplifier drives the motor.

The inputs to the error amplifier are equal and the motor is undriven.

When the DC motor is at stop, it means the motor shaft and potentiometer knob are in its equilibrium position.

A servo motor accepts pulses and outputs rotation.

The operation of the servo motor can be described by the diagram below: It follows the concept of servomechanism.

#High torque servo motor arduino manual#

We recommend using manual pulse lengths if possible: check if you can set your servo controller to custom pulse lengths and try 0.75ms to 2.25ms. Note that the default servo pulse widths (usually 1ms to 2ms) will not give a full range of motion on this servo. Position "0" (1.5ms pulse) is middle, "90" (~2ms pulse) is all the way to the right, "-90" (~1ms pulse) is all the way to the left. To control with an Arduino, we suggest connecting the orange control wire to pin 9 or 10 and using the Servo library included with the Arduino IDE ( see here for an example sketch). Please note, this servo will 'hold' the position even when no signal is sent! Works great with the Motor Shield for Arduino, our 16-channel Servo Driver, or by just wiring up with the Servo library. Of course, it's not nearly as strong as a standard servo. Good for beginners who want to make stuff move without building a motor controller with feedback & gearbox, especially since it will fit in small places. You can use any servo code, hardware, or library to control these servos. The tiny little servo can rotate approximately 90 degrees (45 in each direction) and works just like the standard kinds you're used to but smaller. Add more power to your robot with this metal-geared MG90D servo.

[sammy-ray-blog1]

Didn’t plug output cables from pins 3 and 4 and was losing my mind trying to get my lights to light up. Haha. Got it working now, understanding how the Arduino’s physical pins correspond within the code a little better.

Having trouble finding my analog input range, statement not printing. Because of that I think my lights just aren’t functioning as they’re supposed to BUT I do have an expected response from touching my sensors and seeing the lights react. It is not an on off situation but they do flicker and such. Will need to figure that out... Figured it out!!! I changed the range arbitrarily as my sensors are different kinds of touch sensors, and got it to where the lights turn on and off.

Next moment that gave me trouble was misinterpreting how I should power my LED from the potentiometer, I was drawing a wire from the left side of the bread board to the right side, as you can see in the next image. I wasn’t conceptualizing the Arduino as a command center as much as it is and didn’t realize that the wire from the A9 pin was all that was needed to control the LED. Also the brown wire is coming from the Ground part of my potentiometer which is just a silly mistake on my part.

Once I removed this useless brown wire, my circuit stopped being confused and the dimmer effect worked perfectly!!

At last I figured out where the Serial Console is, was able to figure out readings for the button lab and sensor lab! The “tap”, “short Press”, “long press” lab got me excited for potential for tinkering with some sound reactive things, messing with pitch based on the time... we’ll see.

Use an Arduino touchscreen to draw the waveforms that you’d like your synth to produce

Ordinarily, producing complex waveforms on microcontrollers requires precise adjustments within code in order to work, and this can become quite tedious. Additionally, having to wire up physical inputs such as potentiometers for quick tuning adds a lot of sprawl to a project. This is partially what inspired Kevin, who runs the DIY Electromusic website, to construct a small, Arduino-based device that allows users to sketch the waveform they want outputted via PWM.

The main components of this project are the ILI9488 touchscreen display shield that fits onto an Arduino Uno, along with an amplifier/speaker and an optional output filtering circuit to clean up the audio. Kevin’s unit takes in a MIDI note on the Uno’s RX pin and passes it through a wavetable function that applies the currently shown waveform on the screen to the note being requested.

Kevin also made a slight modification to the previously mentioned project by replacing the wavetable with a series of five sliders that correspond to various parameters for a MIDI granular synthesizer. His analog version had five large potentiometers that plugged into the analog input pins on an Uno, but this newer version greatly cleaned things up and gives more room for experimentation.

To read more about these innovative audio control projects, you can view them on Kevin’s website here and see a quick demo below.

What is a pendant push button switch and how does it works?

Pendant push button:

The pendant push button is used to control the EOT crane or hoist. The crane pendant station controls the overhead crane with a wired mechanism. Many wire cables are connected from the pendant to the control panel. As soon as the switch button is pressed on the control panel then it immediately provides power to the motors. The crane pendant can control the many moments of the crane including the start and stop buttons. The term crane pendant is designed and commonly used to describe the control unit connected to the crane's electronic mechanism. The device is connected to a long cable and hung from an overhead crane like a pendant. Also known as overhang control or overhang control unit. It draws energy from the same power source that powers the crane itself.

 How does the pendant push button switch work?

The pendant push button station works can work with the help of two men. The one who is on the ground floor guiding another man sitting in the cab of an overhead crane or it can be controlled from the ground using buttons or toggle controllers. This control unit can be connected to the crane itself or, like many modern cranes, it can be a remote radio unit. The operator uses a pendant button with a cable attached to the crane and suspended from the overhead crane to control the crane. When the crane crosses the runway, the operator walks alongside the crane. You can use the pendant to control the lifting of the load. Until about ten years ago, all bridge cranes were operated by wired suspension control devices. Industrial machinery, especially EOT Crane & Hoist can be easily controlled from the factory floor. Several combinations of switches can be made using a single speed, double speed, or potentiometer. Any number of buttons requires only four cables of 0.25sq mm main. The button has a top layer of silicones to protect the label from the button.

Types of push-button pendants:

Pendant push button control has many types and they are as follows:

1) Two Buttons:

The EOT crane can be operated in only 2 directions i.e. one up and another in the down direction.

2) Four Buttons:

The four-button push-button pendant switch can control the crane in an up, down, start and stop manner.

3) Six Buttons:

The six-button can comprise the overhead crane in on, off, east, west, up, and down directions respectively.

4) Eight Buttons:

The eight buttons of the pendant switch comprise the hoist crane in up, down, on, off, east, west, north, and south direction.

5) Ten Buttons:

 The ten button push-button switch can operate the EOT crane in on, off, up, down, east, west, north, south, one-speed version, and two-speed version in a respective manner.

 Reason for choosing pendant control switch:

A pendant control device, or simply a crane pendant device, is a crane control device connected to a crane mechanism. This type of devices are used to control EOT crane operations from the ground without the guidance of ground crews. Nowadays, many cranes use radio-operated control equipment, which can be controlled from a distance. Either the radio remote control or pendant crane control both the devices and their own some advantages and some cons so choosing the controlling the device for EOT cranes is absolutely up to you.

Many industries built the pendant for EOT cranes but the best crane pendant control manufacturers in India you will only get from the Anand systems engineering privately limited. Anand pendant cranes are designed in such a way that they can use for harsh conditions industrial purposes. This pendant switch reduces the manpower because sometimes another man is required to operate the cranes.

Post #10: Project Proposal

Project proposal

This project proposal is for the SynthTar, a dedicated music synthesizer built from the components of a single expired home laptop. My aim is to make use of the entirety of the original devices hardware to create a viable musical instrument, wasting nothing. This audio-visual project will demonstrate and uncover the potential and hidden value of obsolete or unused devices for new products, artwork and entertainment. The project will eventually be made open-source to encourage people to replicate it, upcycling the waste in their homes and expanding or developing the ideas.

An old laptop PC will be disassembled into its base components and reassembled into an electronic musical instrument capable of creating sound and visuals. I envision it to be played like a guitar, featuring a main body made from the screen and an extended fretboard design, with PC keyboard keys on the neck to produce notes. The notes could then be manipulated or looped with input devices connected to the internal hardware USB-ports, e.g. a mouse, or an Arduino Midi controller with potentiometers. For example, changing the decay on notes, repeating percussion sequences, and different wave formats.

The sound data would then be translated into visual displays which appear on the laptops original screen. The project is coded with Max, running on the laptop’s processor and internal hardware.

 Rationale

The primary purpose of the project lies in the inherently damaging consumerist culture surrounding technology and electronic devices. Phones, laptops and appliances are designed to become obsolete or break down within a matter of years, so that users have to constantly buy the latest model. This uses non-renewable resources, overseas labour and international shipping, which is harmful for consumers and the environment. Meanwhile, the devices which are no longer useful pile up in landfills or in homes.

This project will demonstrate the power and value of upcycling, where waste is reengineered for new purposes. By making new uses for old technology, it will not go to waste and encourage people to engage with this issue in ways they find enjoyable.

The project aims to be both artistic and functional in its rationale, drawing from the likes of Electronicos Fantasticos, who have achieved cultural success and recognition with similar ideas.

The secondary rationale is the visual spectacle and interest factor of the proposed product. People are naturally drawn to unique or novel ideas, particularly over the internet, meaning that others will be able to find entertainment in the project from afar and lend attention to the primary rationale. I believe the project has a good chance to succeed in this aspect.

 Build plan

Obtain     an unused laptop and disassemble it into its various components. Observe     and make note of how different components connect and should be     reassembled. (2 days)

Make     detailed sketches of the design for the device to follow later (2 days)

Produce     main synthesizer program on MAX. Develop the groundwork for a complex MIDI     output device with a patch that creates simple notes based on key presses.     Create triggering method and output for sounds. (5-10 days)

Add     to the initial patch with necessary features such as looping, different     sound styles (i.e. the sound of the synth and wave shape, percussion     sounds and instrument imitation) and modifiers. (10-15 days)

Source     scrap material for the main structure, including metal beams and wood.     Design the structure based on materials at hand- This should be a simple     frame, and will expose the internal wiring of the device for aesthetic     effect. Construct it using basic methods, i.e. with Duct tape. (5-8 days)

Reassemble     the laptop components in the desired fashion. Apply them securely to the     structure. Add USB devices, external speaker, and MIDI controller. (3     days)

Copy     Max patch copy to the internal laptop hard drive and run it on the new     device.

Test     the finished synthesizer and make final adjustments. (3 days)

 Risks

•       The laptop components become damaged, break down or are otherwise unusable.

•       Computer hardware is quite fragile and will break easily if mistreated. This could cause the entire setup to be ruined and a new laptop would have to be sourced. Great care will need to be taken in disassembling and reassembling.

•       Too much time is spent on the MAX synthesizer patch, and not enough left to turn it into the proposed instrument.

•       Creating the minimum viable product is important but leaving it at such a stage somewhat defeats the rationale.

•       That the laptop cannot be reassembled at the end. Make the hardware exposed to repair and replace where needed.

•       Soldering work or other more difficult processes are required. I will ensure I have access to such tools early on.

•       Unable to source frame materials from waste. The plan is structured to leave this element until near the end to allow more time to find suitable components.

 Legacy

If the project succeeds, it will provide a new method for engaging with old or unused electronic items which can be followed by others and create a new form of musical instrument.

I expect the project to develop my personal skills in presenting coding work to audiences, as well as my technical expertise in working in MAX and generally with Synthesized sound and midi signals- versatile skills which can be applied further to future projects. I hope that the project principles will help encourage people to rethink their approach to the technological waste mounting in their homes and open new ideas about the treatment of waste.

To this end, I hope that the project will find success on the internet and particularly on social media for its entertaining design and premise, if nothing else.

Expected outcome: A working SynthTar running the Max patch. A viable musical instrument which has a pleasant sound, captures the imagination and sticks as much as possible to waste material.

Minimum Viable Product: A working Max patch which functions as a synthesizer, running on an old laptop.
