Here's 2 Eurorack Modules Built From Scratch Using Otto DIY

The Indiegogo campaign for the Otto DIY Eurorack Module system ends soon - these examples of what you can do with it may surprise you.  

Not so long ago we told you about a new startup that was aimed at letting people prototype and develop their own Eurorack gear at a sensible cost. You can check it out at

Now the Indiegogo campaign is almost over, and the developers have shared two examples of models that have been built using their system. They're well worth a look and may inspire you to get involved when you see what can be achieved. 


"We have plenty of different Arduino boards laying around in the office. In hobby electronics Arduino is popular, so we thought utilizing one as part of a eurorack module might be interesting. The coolest thing in the Arduino based design is that it can do whatever you want. This module is programmed to have multiple clock division outputs (x1 x0.5 and x0.25 ). One knob controls the tempo, the other controls the maximum amount of swing (random time jitter) in the output."

Otto's Monotron 

"Planning and building user interface with Otto's DIY is easy. Many try to interface guitar pedals and other gadgets with the eurorack format. Such mods are usually harder to execute than they look at first sight. But not with Otto's DIY, as the format is already given with the combination of panels and the PowerBrick. We modded the Korg Monotron Duo to demonstrate how Otto's DIY can be used for a modding job."
