Bitwig playing some music, with a webcam view of the device. It is a white plastic blob with a usb cable going in and a silicon tube. The blob changes color depending on how hard and if you suck (blue) or blow (green), or red for under/over pressure. There is also a live graph of the MIDI data.

I decided to work with the garage door up (https://notes.andymatuschak.org/Work_w ith_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_s ynth_controller/

Rendering of Plan 2 seen from the front with a Raspberry Pico on the top left, a tiny oled screen on its right a jack on the right of the screen. Below the screen are two jacks that cannot be seen on this render. There are 8 potentiometers vertical. A button and pads arranged in 4x3

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.

a small board 28x22mm with two 3.5mm jacks, an optocoupler and two microscopic leds. you can see connectors for 3v3 gnd tx and rx. the board is green components are black and the jack connectors have some gold metal.

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.

a small board with a raspberry pico on it mounted on headers on the right. on the left, we can see 5 jack 3.5mm ports, and 5 other on the other side of the board. There is a cable connecting two port together and leds that blink showing which port is sending/receiving data.
