Solderless build system for audio experimenting. it's a hybrid offering the convenience of solderless breadboards, matched with robust "QICBoards" which include common connectors and controls, as well as subsystems like CV DACs, mixers, etc.
There are 4 QICBase boards – two for smaller protoboards, and two for larger ones.
Here's an example of a smaller QICBase board hosting an Atari Punk Console:
For this example, the QICBoards provide three 1/8" jacks and three potentiometers.
This QICbase is designed to fit onto a Hammond 1590BB enclosure (without the cover):

It takes 15V from a desktop supply and generates +/-12V and +5V for the breadboard and QICBoards.
