Vertical Modular Synthesizer “CD Rack Format”

I'm planning on building a series of MIDI synthesizer modules that will have a pretty simple means of hooking them together, but want something to house them. I also have a couple of IKEA CD racks kicking around that haven't been required for a while, and I also don't want to take up large chunks … Continue reading Vertical Modular Synthesizer “CD Rack Format”

Toy Keyboard Matrix Decode with the Pi Pico

I'm always on the look out for discarded music keyboards that I might be able to do something with, so when I came across this thrown out in the street I claimed it to take a look. This shows how I used a Raspberry Pi Pico to decode the keyboard part and turn it into … Continue reading Toy Keyboard Matrix Decode with the Pi Pico

Vintage Phone USB MIDI Controller

This is the USB MIDI controller version of the Vintage Phone MIDI Controller.  As the USB MIDI support is much easier in CircuitPython than MicroPython, this is also a version of the keypad controller code for CircuitPython too. Warning! I strongly recommend using old or second hand equipment for your experiments.  I am not responsible for … Continue reading Vintage Phone USB MIDI Controller

Arduino Top Octave Generator – Counter Experiments – Part 2

This is an incomplete experiment, but I wanted to test the principles from Arduino Top Octave Generator and Arduino Top Octave Generator – Counter Experiments in practice a little more. You may recall the basic idea here is to generate 12 tones using an Arduino and then use binary counters to divide them by 2 several … Continue reading Arduino Top Octave Generator – Counter Experiments – Part 2

Arduino Top Octave Generator – Counter Experiments

After building my Arduino Top Octave Generator I went off an ordered some binary counter devices to use to produce some "lower octaves". This is a test run project to explore how the 74HC393N devices I have work. In part 2 I start to explore how to expand this to multiple keys and octaves. https://youtu.be/MO8jG0fjUSU Warning! … Continue reading Arduino Top Octave Generator – Counter Experiments

Simple Potentiometer Breakout

I've been using potentiometers quite a bit in recent projects and now have two boards that include options to link out to potentiometers to control boards too, so thought it useful to have another, smaller, breakout to make experimenting easy. Warning! I strongly recommend using old or second hand equipment for your experiments.  I am … Continue reading Simple Potentiometer Breakout
