I've been meaning to have a try at PCB design for a while. I'd like to add it to the list of things I'm amateurly enthusiastically ignorant about. I've not seen anything like my Arduino Uno Dual Merge MIDI “Shield” available anywhere but it is built of individual designs I am very familiar with, so I … Continue reading Arduino Uno Dual Merge MIDI “Shield” – Part 2

Arduino Uno Dual Merge MIDI “Shield”
Having spent some time now playing with a range of MIDI merge options, one final thing I wanted to do was have a "merge shield" that could quickly turn an Arduino Uno into a simple two-in, one out MIDI unit. Warning! I strongly recommend using old or second hand equipment for your experiments. I am … Continue reading Arduino Uno Dual Merge MIDI “Shield”
“Bare Metal” Raspberry Pi MiniDexed DX7 – Part 2
This is a continuation of my exploration of MiniDexed. In part 1 I built a basic breadboard version. In this part, I've built a DIY "MiniDexed HAT" for a 40-way GPIO Raspberry Pi. Update: There is also now a custom PCB too: MiniDexed Raspberry Pi IO Board. https://youtu.be/7gKDfDWLHzw Warning! I strongly recommend using old or second … Continue reading “Bare Metal” Raspberry Pi MiniDexed DX7 – Part 2
Arduino MIDI Telephone Ringer – Part 3
The last thing I wanted to do with my (dual) telephone ringer, well, besides trying to find six more phones and get an octave's worth of ringing, was put my dual-ringer into a box. This shows how I managed that. In part 1 I talked about the basic hardware and approach. In part 2 I … Continue reading Arduino MIDI Telephone Ringer – Part 3
Arduino Nano MIDI IN “Shield”
This is "yet another" Arduino MIDI Interface, after all I don't think I've built one for a few months now... Actually I need this for another project, but thought it worth of writing up on its own first. A Nano "shield" type MIDI In might be useful elsewhere too! Warning! I strongly recommend using old … Continue reading Arduino Nano MIDI IN “Shield”
Raspberry Pi Pico Multi MIDI Router – Part 3
The obviously missing part of my Raspberry Pi Pico Multi MIDI Router is the use of USB MIDI. The Pico should support both USB host and device functionality, but I think you need to get into the C software development kit to do that properly, something I've not looked at yet. One of the easiest ways … Continue reading Raspberry Pi Pico Multi MIDI Router – Part 3
Arduino MIDI Telephone Ringer – Part 2
Following on from part 1, I've added BT style sockets and upgraded the ringer to ring two phones. Polytelephony if you will. In part 3, I switch to an Arduino Nano and put all the circuitry into a box. https://youtu.be/IBBd9z4hKYw Warning! I strongly recommend using old or second hand equipment for your experiments. I am … Continue reading Arduino MIDI Telephone Ringer – Part 2
Arduino MIDI Telephone Ringer
One thing I love about those vintage rotary telephones is the characteristic ring. But making them do that outside of being plugged into the PSTN isn't easy. But I wanted to see if I could make it work over MIDI, so this is my approach. In part 2 I add some BT style sockets and … Continue reading Arduino MIDI Telephone Ringer
Yet Another Toy Keyboard USB MIDI Controller – Part 2
So this follows on from the first part and adds MIDI, some buttons to control the keyboard and gives it a voice of its own. https://youtu.be/NUaCPR0LRTM 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 microcontrollers, … Continue reading Yet Another Toy Keyboard USB MIDI Controller – Part 2
Yet Another Toy Keyboard USB MIDI Controller
Ok, I admit, there is a bit of a theme to some of my projects, but this keyboard that I found in a charity shop was such a dinky thing that I had to do Just One More (TM). Warning! I strongly recommend using old or second hand equipment for your experiments. I am not … Continue reading Yet Another Toy Keyboard USB MIDI Controller
