#DIY electronics with Raspberry Pi

[operator-4rch4ng3l]

[CYBERDECK PROJECT ACTUAL NAME YELIEL ONLINE]

My cyberdeck is functional, I included an internal shot as well. I have plans on adding a power switch to the front cover, a retractable USB cable (EG Ghost in the Shell), a modular system for the back to house Extra Battery banks and other accessories. This project was a long time coming and instead of 3d printing a shell I found that this container I had full of sharpies was a suitable housing and adds to the "Jank" Factor. I also plan on stickerbombing the back, possibly a hanging charm, and possible LED lights inside the housing.

need a bit of advice on something rather new to me... i have been DYING to get into some semblance of diy electronics/robotics, specifically regarding the idea of building a flipper zero knockoff with a raspberry pi/esp32/arduino. or a hack rf one ripoff, etc. u get it? i wanna make a lil handheld pwnagotchi pet style device for rolljam rf shit, something that can copy and paste and send and receive rf signals, but homemade by my self....

please if anyone has experience, resources, ideas, anything at all= hit me up right now immediately asap today please.... i am so passionate and ready to do this please help me make device go beepboop

I made a thing! It's a DIY synth, shoved in an old junction box and given the most lurid paint job imaginable 🎨

Basically 8 DX7s combined, like a Yamaha TX816 except it cost me like 50 bucks instead of 2k

Looks mad, sounds fantastic!

Project is Minidexed, if you want to make one yourself

(You can probably make it a lot neater than mine)

A4988 Pinout: A Comprehensive Guide

Discover the functionality and versatility of the Stepper Motor Driver Module A4988 Pinout, a crucial component in the world of robotics and automation. Let’s delve into the key details, with a specific focus on the A4988 pinout for a clearer understanding.

Stepper Motor Driver Module A4988

The A4988 is a stepper motor driver module that plays a pivotal role in controlling the precise movements of stepper motors. Whether you’re working on a 3D printer, CNC machine, or any other project requiring accurate motor control, the A4988 is a go-to choice.

A4988 Pinout Configuration

Understanding the A4988 pinout configuration is essential for effectively integrating the A4988 into your projects. Here’s a breakdown of the key pins:

MS1, MS2, MS3 (Microstep Resolution): These pins determine the microstep resolution, allowing you to set the stepping mode for the stepper motor. Configuring these pins enables fine-tuning of motor movement.

VMOT (Motor Power Supply Voltage): Connect this pin to the motor power supply voltage (typically 8V to 35V) to ensure the proper functioning of the stepper motor.

GND (Ground): Establish the ground connection by linking this pin to the ground of your power supply or microcontroller.

VDD (Logic Power Supply Voltage): Provide the logic power supply voltage (typically 3V to 5.5V) to this pin to power the internal logic circuitry of the A4988.

DIR (Direction Input): Control the direction of the stepper motor by connecting this pin to a digital output on your microcontroller.

STEP (Step Input): Trigger individual steps of the stepper motor by connecting this pin to another digital output on your microcontroller.

RESET (Reset Input): This pin resets the internal translator circuit, and it is optional to use.

SLEEP (Sleep Input): Putting the A4988 into sleep mode is achieved by connecting this pin to a digital high signal.

Pi Extension board "PiEBridge"

"PiEBridge" is an extension board for microcomputers similar to the Raspberry Pi (Pi), which is designed to be a helper for the DIY-maker in all his activities - Pi, together with PiEBridge, can perform a variety of functions:

universal programmer

software and hardware debugger for target systems

PCB fusion furnace controller

smart-home controller

as well as do many other useful things

You might say Pi already knows how to do these useful things, so why does it need more extension boards? Here is the answer to that question:

PiEBridge transforms the Pi's 40-pin I/O subsystem into more practical 6/10-pin lines for many applications and provides signal integrity for these lines

adds the simplest controls and indications (button, pedal, and LEDs)

has a programmable 2.5...5V power supply for external devices

"Naked" Pi is usable in two extreme configurations - either just a box controlled externally via SSH or a desktop computer with a monitor, keyboard, and often even a mouse. In addition to these typical use cases, PiEBridge allows you to use the Pi as a standalone software automaton to perform random repeating tasks with minor interactive operator participation.

PiEBridge is plugged into the Pi extension connector (compatible with family models with a 40-pin connector) and installed vertically. For this purpose, the Pi case (if available) must have a corresponding cutout on top.

When used as a programmer, PiEBridge can work with most known 6-pin and 10-pin connectors, and GND and Vcc can be randomly connected to their pins to ensure compatibility.

The programmable power supply for external devices is programmable on/off and programmable in the range of 2.5 - 5V with an accuracy of about 2%.

Deb-packages for PiEBridge have been created and compiled into a repository:

general-purpose, providing configs and libraries for working with controls and indications, as well as with the power supply

special purpose, e.g., applications for MCU and FPGA programming and debugging

auxiliary purpose, for example, for repeating operations automation (like mass-production function for firmware flashing). In this case, the user can use settings that provide autonomous launching of the necessary software when the Pi is turned on, and then (after finishing its work) its simple parking and shutdown by pressing and holding the button for a long time.

metapackages, which cause installation of necessary software and configs for the selected role and allow to simplify preparation for work

Victory!

It's a whole entire rats nest and I can't keep little hands away, but I managed to get signals routed and audio generated

Woohoo! I'm on vacation, but rainy afternoon is a perfect excuse to play with my toys. Accomplishments for the day consist of:

Teensy is receiving MIDI

PC is routing messages from the virtual keyboard to the Teensy

Next steps:

Get Raspberry Pi set up as the midi hub

Get neotrellis sending messages to the hub/Teensy

Get the Teensy responding to midi (one of my goals is a Karplus-Strong implementation)

Get the ATMega32U4 that I brought along on this trip playing too
