This idea came from watching the YouTube channel of Kristian Blåsol. It’s a quad logic module based on the 4000 series chips. These chips have the same pin outputs for different functions. Swapping the chip will make the module AND OR XOR NOR NAND.
Here is the original posting on YouTube for this module
This is a really nice module for making beats and affecting different clock signals to make new rhythms and polyrhytmic beats.
There is a hole in the panel to make it possible to swap the chip and give the module a different mode (AND OR XOR NOR NAND)
The module is SMD but these components are soldered. So you only need the solder the thru hole parts yourself when you order the kit, or PCB and panel.
