Raspberry Pi Pico Synth_Dexed – Revisited

I thought it was time I took another look at my Raspberry Pi Pico Synth_Dexed. I've a couple of main aims with coming back to this project: Update the build for the latest Pico SDK and Synth_Dexed. See what is involved in getting it running on an RP2350. See if a simple I2C display can be … Continue reading Raspberry Pi Pico Synth_Dexed – Revisited →

MT32-Pi on my EuroRack MiniDexed PCB

This is great. I was asked by Michel (mragutlich) if I knew how to build MT32-Pi to configure it for my MiniDexed EuroRack PCB but I don't and there isn't a lot of information apparently on how to build it from source. So I offered my Rebuilding my Ability to Build MiniDexed post which talks about … Continue reading MT32-Pi on my EuroRack MiniDexed PCB →

ESP32-A1S Audio Kit

I've had this "audio development kit" based on the ESP32-A1S for some time, but haven't actually done anything with it so far. But I had a query about adding MIDI so dug it out for a quick look. It turns out it isn't actually as easy as it ought to be! Warning! I strongly recommend … Continue reading ESP32-A1S Audio Kit →

Using a Cheap 5V MIDI Interface at 3V3

I had a query about using one of the common Arduino MIDI Shields with an ESP32 and when I looked into it, this is where I got to. 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 … Continue reading Using a Cheap 5V MIDI Interface at 3V3 →

Duppa I2C MIDI Controller – Part 4

This is revisiting my Duppa I2C MIDI Controller this time using a Waveshare Zero format device. Part 1 - getting to know the devices and testing them out. Part 2 - adding MIDI to the LED ring and I2C encoder. Part 3 - adding normal encoder, plain potentiometer, and endless potentiometer control. Part 4 - revisits the idea with … Continue reading Duppa I2C MIDI Controller – Part 4 →

Forbidden Planet “Krell” Display – MIDI CC Controller – Part 2

This revisits my Forbidden Planet “Krell” Display – MIDI CC Controller using my Forbidden Planet “Krell” Display PCB with a Waveshare RP2040 to create more of a "all in one" device. 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 … Continue reading Forbidden Planet “Krell” Display – MIDI CC Controller – Part 2 →

Forbidden Planet “Krell” Display EuroRack Module

This project uses my Forbidden Planet “Krell” Display and the Forbidden Planet “Krell” Display PCB Design but with some slight variations that means it could be EuroRack mounted with a control voltage (CV) input. This is a DIY module only for use in my own DIY system. Do NOT use this alongside expensive modules in an … Continue reading Forbidden Planet “Krell” Display EuroRack Module →

Minimalist Lo-Fi Minimalism

Whilst I'm not an ardent fan of Philip Glass, (more like an amateur enthusiast), there are certain pieces of his that I do really quite like. The violin concerto goes without saying - some parts of that are wonderful. And I quite like the Low Symphony based on the music of David Bowie. But the … Continue reading Minimalist Lo-Fi Minimalism →

Forbidden Planet “Krell” Display PCB Build Guide

Here are the build notes for my Forbidden Planet “Krell” Display PCB. This post just looks at building the PCB for standalone use. Further posts will explore other uses for this PCB: Forbidden Planet “Krell” Display EuroRack Module Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible for … Continue reading Forbidden Planet “Krell” Display PCB Build Guide →

Forbidden Planet “Krell” Display PCB Design

This is a PCB to support one of my dual Forbidden Planet “Krell” Displays. Rather than using ready made programmable LED rings, this is using through-hole APA-106 programmable RGB LEDs.
