Optocoupling interface for circuit bent gear
Heksens Negl has 8 identical optocoupler circuits that lets you interface external button presses safely with your eurorack.
If you are into circuit bending this is a very practical way of controlling things without having to worry about unwanted electrical interference between different power systems.
All you need to do is to break out the two points that needs to connect in order to activate a button/bend and connect them to a jack, patch a cable from there to one of the upper output jacks on Heksens Negl and you are ready to go!
Available as a full kit - 50$ + shipping
