Atari Synth Cart Controller

This project uses my Atari 2600 Controller Shield PCB in reverse, to allow the Arduino to act as an Atari keypad controller and thus allow it to control the Atari Synth Cart. https://makertube.net/w/ryCciwFyQQpcs1Q4Wwy52x Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible for any damage to expensive … Continue reading Atari Synth Cart Controller →

XIAO ESP32-C3 MIDI Synthesizer – Part 6

Expanding on my previous posts, I thought it might be interesting to see how I might be able to add some additional IO to the MIDI Synth. This is an exploration of some options there. Part 1 - Getting started and getting code running. Part 2 - Swapping the ESP32-C3 for a SAMD21 to get USB … Continue reading XIAO ESP32-C3 MIDI Synthesizer – Part 6 →

XIAO USB Device to Serial MIDI Converter

Having recently revisited the CircuitPython USB to Serial MIDI Router as part of XIAO ESP32-C3 MIDI Synthesizer – Part 2 it reminded me I didn't really have a simple Arduino USB device to serial MIDI for the XIAO. So this is filling that gap. Warning! I strongly recommend using old or second hand equipment for your experiments. … Continue reading XIAO USB Device to Serial MIDI Converter →

Arduino Atari MIDI Keypad

This uses my Atari 2600 Controller Shield PCB and a pair of Atari 2600 keypad controllers to see if they can be used as some kind of MIDI controller. https://makertube.net/w/7VoDLuAWbiHuMr21XszyD4 Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible for any damage to expensive instruments! These are … Continue reading Arduino Atari MIDI Keypad →

Arduino MIDI Atari Paddles

Finally, I get to the point where I can do something vaguely musical with my Atari 2600 Controller Shield PCB. This turns it into a simple MIDI CC controller using the Atari paddles. https://makertube.net/w/dgK7y73KfC1SWc5z2wsJ6x Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible for any damage to … Continue reading Arduino MIDI Atari Paddles →

USB MIDI to Serial and CV/GATE

This project uses my Arduino Pro Mini MIDI USB CV PCB for a USB MIDI to Serial MIDI and CV/GATE device that has a CV/GATE that is compatible with my Korg Volca Modular. It takes MIDI NoteOn/NoteOff and translates them into CV that can be used to set the pitch of a CV/GATE synth. IMPORTANT: … Continue reading USB MIDI to Serial and CV/GATE →

Duppa I2C MIDI Controller 3D Print Case

This is a simple 3D printed case for my Duppa I2C MIDI Controller PCB. https://makertube.net/w/nf7u1sYBRRzj2TUBRduQC2 Warning!

Duppa I2C MIDI Controller PCB Design

This is the design for a simple carrier PCB for a Waveshare Zero format microcontroller and a Duppa small LED Ring. It is essentially a PCB version of Duppa I2C MIDI Controller – Part 4. Duppa I2C MIDI Controller PCB Build Guide Duppa I2C MIDI Controller 3D Print Case Warning! I strongly recommend using old or second hand … Continue reading Duppa I2C MIDI Controller PCB Design →

Duppa I2C MIDI Controller – Part 4

This is revisiting my Duppa I2C MIDI Controller this time using a Waveshare Zero format device. Part 1 - getting to know the devices and testing them out. Part 2 - adding MIDI to the LED ring and I2C encoder. Part 3 - adding normal encoder, plain potentiometer, and endless potentiometer control. Part 4 - revisits the idea with … Continue reading Duppa I2C MIDI Controller – Part 4 →

Forbidden Planet “Krell” Display – MIDI CC Controller – Part 2

This revisits my Forbidden Planet “Krell” Display – MIDI CC Controller using my Forbidden Planet “Krell” Display PCB with a Waveshare RP2040 to create more of a "all in one" device. Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible for any damage to expensive instruments! If you … Continue reading Forbidden Planet “Krell” Display – MIDI CC Controller – Part 2 →
