The Clunker is a 40% DIY kit with a knob and solenoid. We wanted to create a board that utilized a solenoid and as millennials, we frequently wondered what that weird noise coming from our cars was. We have fused those 2 ideas into the Clunker.

The kit includes everything you need to have a functioning PCB, you’ll need to provide your own switches, stabilizers, keycaps, and USB cable.
