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 →

This is a follow up post to Part 1 where I'm starting to look at MIDI applications and a range of control options. 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. … Continue reading Duppa I2C MIDI Controller – Part 2 →

Remotely Analysing a Keyboard Matrix

I've been having a conversation on discord helping someone to try to work out the keyboard matrix of a keyboard in order to eventually use it with a microcontroller. But discord being discord, its fine for chat, but we're both starting to lose track of where we're at in the analysis, so I thought I'd … Continue reading Remotely Analysing a Keyboard Matrix →
