MiniDexed TX816 – Part 4b – PCB Build Guide – IO Board

This is the second build guide, this time for the IO board.  The build guide for the Raspberry Pi Interface Board can be found here. Posts in this series: Part 1: Introduction, context, and high-level design. Part 2: PCB design. Part 3: Panel design. Part 4: PCB assembly. Part 5: Mechanical assembly. Part 6: Pico … Continue reading MiniDexed TX816 – Part 4b – PCB Build Guide – IO Board →

MiniDexed TX816 – Part 4a – PCB Build Guide – RPi Interface Board

I'm not going to do full build guides for the PCBs for this, but I will be documenting in high level terms how they are put together. There are two build guides, this one for the Raspberry Pi Interface board and a second one (4b) for the IO board. Posts in this series: Part 1: … Continue reading MiniDexed TX816 – Part 4a – PCB Build Guide – RPi Interface Board →

Pico, Nano, Micro Keyboard Matrix PCB

A number of my projects have involved using a microcontroller (usually an Arduino Nano or a Raspberry Pi Pico) to decode a music keyboard matrix and take some action.  This is the basis of all of my "toy keyboard" MIDI controllers for example. This board is a "helper" PCB that makes the job a little … Continue reading Pico, Nano, Micro Keyboard Matrix PCB →

Raspberry Pi Pico MIDI Channel Muter

This project uses a Pimoroni RGB Keypad with a Raspberry Pi Pico to create 16 "mute" switches for MIDI, one for each MIDI channel. https://youtu.be/8KiXT91sSk8 Warning! I strongly recommend using old or second hand equipment for your experiments.  I am not responsible for any damage to expensive instruments! These are the key tutorials for the … Continue reading Raspberry Pi Pico MIDI Channel Muter →

Raspberry Pi Pico MIDI Splitter (TTL) – Part 2

This is the build guide for my Raspberry Pi Pico MIDI Splitter (TTL). Tutorials used in this project: Raspberry Pi Pico MIDI Channel Router Raspberry Pi Pico Multi MIDI Router – Part 4 Notes on KiCad for PCB design: Arduino Uno Dual Merge MIDI “Shield” - Part 2 If you are new to microcontrollers, see the Getting Started … Continue reading Raspberry Pi Pico MIDI Splitter (TTL) – Part 2 →

Raspberry Pi Pico Dual MIDI Carrier – Part 2

This is the build guide for my Raspberry Pi Pico Dual MIDI Carrier to support my dual-MIDI interfaces for a Raspberry Pi Pico designed by @VE7FIM from Twitter.  Although designed largely for my own personal use with that specific dual-MIDI module, it could still also be used to link to several off-the-shelf MIDI modules if required. If … Continue reading Raspberry Pi Pico Dual MIDI Carrier – Part 2 →

Getting Started with the Raspberry Pi Pico C/C++ SDK and TinyUSB MIDI

I've been meaning to take a proper look at the Raspberry Pi Pico C/C++ SDK for quite some time, but have been putting it off.  With good reason it would appear!  But I've finally got to the start of being able to build the Tiny USB test MIDI application myself and so have a good … Continue reading Getting Started with the Raspberry Pi Pico C/C++ SDK and TinyUSB MIDI →

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 →
