Raspberry Pi Pico Dual MIDI Carrier

I mentioned in Raspberry Pi Pico Multi MIDI Router - Revisited that I have several dual-MIDI interfaces for a Raspberry Pi Pico designed by @VE7FIM from Twitter.  In that post I built a simple proto-board carrier for the Pico.  In this post I have a pcb design for something to do the same.  This is definitely … Continue reading Raspberry Pi Pico Dual MIDI Carrier →

Zynthian Revisited – Part 3

Following on from my prototype IO boards for my Zynthian, here is a PCB design that will hopefully work much better. Update: Find the Build Guide here: Zynthian Revisited – Part 4 Warning! I strongly recommend using old or second hand equipment for your experiments.  I am not responsible for any damage to expensive instruments! … Continue reading Zynthian Revisited – Part 3 →
