Arduino and SP0256A-AL2 – Part 3

Following on from using an Arduino as a variable clock in Arduino and SP0256A-AL2 – Part 2, I have some ideas for a few options, but this post looks in detail at using a Raspberry Pi Pico as the clock source. Spoilers: it kind of works, but isn't quite the answer I need yet... Part 1 … Continue reading Arduino and SP0256A-AL2 – Part 3 →

Pico Touch Board Audio

I wanted to go back to my Pico Touch Board PCB Design and see if there was a way to make it more stand-alone. The original design was to make it a MIDI controller, but that isn't the only option. https://makertube.net/w/tADSyrPrUdR1mx7yKRXZTC Warning! I strongly recommend using old or second hand equipment for your experiments. I am … Continue reading Pico Touch Board Audio →

picoDexed + MiniDexed EuroRack

Since attempting my picoDexed + StackyPi + MiniDexed EuroRack build and failing, I've found another Pico-to-Zero board that is provided as open source, so I've had some made. This post details how to get that running with my MiniDexed Zero Eurorack module. Warning! I strongly recommend using old or second hand equipment for your experiments. I … Continue reading picoDexed + MiniDexed EuroRack →

picoDexed + StackyPi + MiniDexed EuroRack

Now that I have a picoDexed with a display an encoder it is very tempting to create a version of my MiniDexed EuroRack PCB for it. But as a short diversion, there is another possibility - can I use a RP2040 that is already in a Pi Zero form factor with my existing MiniDexed EuroRack … Continue reading picoDexed + StackyPi + MiniDexed EuroRack →

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 →

EuroRack 6HP MCU Experimenter Module

I've been following the work of HAGIWO for some time and always been really impressed with the breadth and range of modules they produce. I have noticed some patterns in their microcontroller based modules and so wondered if it was possible to build some kind of generic template PCB that would allow me to do … Continue reading EuroRack 6HP MCU Experimenter Module →
