Atari 2600 Controller Shield PCB Build Guide

Here are the build notes for my Atari 2600 Controller Shield PCB Design. Recall from my design notes that this version doesn't deal with paddles very well Here is an updated version that supports paddles better, but at the expense of requiring more complex code to read them: Atari 2600 Controller Shield PCB Revisited. Warning! I strongly … Continue reading Atari 2600 Controller Shield PCB Build Guide →

Using a Cheap 5V MIDI Interface at 3V3

I had a query about using one of the common Arduino MIDI Shields with an ESP32 and when I looked into it, this is where I got to. 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 are new … Continue reading Using a Cheap 5V MIDI Interface at 3V3 →

Minimalist Lo-Fi Minimalism

Whilst I'm not an ardent fan of Philip Glass, (more like an amateur enthusiast), there are certain pieces of his that I do really quite like. The violin concerto goes without saying - some parts of that are wonderful. And I quite like the Low Symphony based on the music of David Bowie. But the … Continue reading Minimalist Lo-Fi Minimalism →

Simple MIDI Touch Button Keyboard

I've grabbed some very cheap TTP223-based touch pad PCBs so this is showing how they can be used as a replacement button in a simple Arduino MIDI controller. 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 the key … Continue reading Simple MIDI Touch Button Keyboard →

Simple MIDI Transpose

I've done a number of MIDI processing projects, but was always planning to go back and build up some kind of catalogue of common actions that could be taken. But so far I've not done it, but when a question came in asking about the possibility of a MIDI transpose function, I thought I'd put … Continue reading Simple MIDI Transpose →

Arduino MIDI Master Volume Control

This project uses an Arduino Uno or Nano with a potentiometer to create a MIDI Master Volume Control. 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 the key Arduino tutorials for the main concepts used in this project: … Continue reading Arduino MIDI Master Volume Control →

Arduino MIDI to Clock Trigger

This is another project for my Arduino Clock Generator Shield PCB. This one takes a MIDI clock sync pulse and outputs trigger pulses as required. https://makertube.net/w/obgH4asW3hqk2pHKKrPoAc 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 are new to Arduino, see … Continue reading Arduino MIDI to Clock Trigger →

ION iDM02 and Arduino

I picked up an ION iDM02 drum module, with five pads and a single pedal, and most of the frame missing a while back and always wondered if I could get it doing something interesting. As is becoming usual with these types of posts, this is a collection of things I've found out about the … Continue reading ION iDM02 and Arduino →

Arduino Euclidean Gate Sequencer – Part 4

In this posts I describe a version of the Arduino Euclidean Gate Sequencer that implements the same user interface and most of the features of HAGIWO's brilliant build. Part 1 covered all the theory and main functions of the code. Part 2 included some hardware suggestions for connecting it to other devices. Part 3 added a rotary encoder … Continue reading Arduino Euclidean Gate Sequencer – Part 4 →

Arduino Euclidean Gate Sequencer – Part 3

This is another variant of my Arduino Euclidean Gate Sequencer this time using a rotary encoder and I2C display rather than a potentiometer for control. Part 1 covered all the theory and main functions of the code. Part 2 included some hardware suggestions for connecting it to other devices. Part 3 added a rotary encoder and I2C display … Continue reading Arduino Euclidean Gate Sequencer – Part 3 →
