Made a #MIDI breath-controller. Surprisingly reactive. #rp2040 #controller #blob #bitwig #arduino

MIDI Breath controller - Bjonnh.net

I made a tiny device that uses pressure from my mouth to control MIDI.

The boards for the #midi controller workshop at #pumpingstationone #chicago are working!
And they will also be a synthesizer because there was some budget left to add an i2s board. #rp2040 #arduino #synth #openhardware #opensource.
More details to come.

EMMG Midi Synth - Bjonnh.net

I’m organizing a MIDI workshop at PumpingStation One sometime in 2024. I decided to try to Work with the garage door up, and share everything as I am doing it. This is not meant to be a full-fleshed finished documentation more splattering my brain on a wall so I can see more clearly

I decided to work with the garage door up (https://notes.andymatuschak.org/Work_with_the_garage_door_up) on my new project for a MIDI controller workshop. Inspired by @diyelectromusic and @todbot designs. This is a #midi controller and #synth that also does USB midi interface hopefully below $20. Can be followed at: https://www.bjonnh.net/project/emmg_midi_synth_controller/

Made some mini #midi 3v3 interface boards to easily add midi to microcontroller projects (mostly #rp2040 #raspberrypico these days) They even have micro leds that tell you when signal flows in or out.

Minitopus - Bjonnh.net

A small (28x21mm) MIDI board for your microcontroller projects. Especially for RP2040/Pico projects or other 3V3 boards.

The v2 of the midi router works great. It is much smaller than v1 and easier to make (90% soldered by JLCPCB). All configurable using sysex and with a webui if necessary.

DINOctopus - Bjonnh.net

DINOctopus is a 10 ports small device made that can merge/split/mix MIDI signals and act as a USB interface.

DINOctopus has a logo now
And files ready to upload on a RP2040.
Next easier instructions to build one and better PCBs.
