CakeBox 30HP EuroRack Lid

Now that I'm doing more messing around with EuroRack style modules, I was on the lookout for a simple means of testing them "on the bench". As I was scanning around, for different ready-made containers I might be able to use, I settled on the spare plastic cake boxes we have lying around. These often … Continue reading CakeBox 30HP EuroRack Lid →

EuroRack 6HP Arduino Mozzi Module – Basic VCO

This is the first project based on my EuroRack 6HP Arduino Mozzi Module. It is loosely based on HAGIWO's Arduino Mozzi VCO Module. https://makertube.net/w/hnocMAhYkajd8nX2vwuR2u 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 some previous posts for the main concepts … Continue reading EuroRack 6HP Arduino Mozzi Module – Basic VCO →

EuroRack 6HP Arduino Mozzi Module

This project uses my EuroRack 6HP MCU Experimenter Module to implement HAGIWO's Arduino Nano based VCO. This post describes how to put it together and test the basic functionality. Future posts will look at some code that can run on the module (see the "Sample Applications" section). Warning! I strongly recommend using old or second hand … Continue reading EuroRack 6HP Arduino Mozzi Module →
