Arduino 8-bit synth case

This case was designed after reading a new magazine called Hackspace. In this issue a man named Chris Ball shows how to turn an Arduino uno in to a 8-bit synth.
i like the uno basics kits you can get off Ebay and the Adafruit perma-proto, so i desgined this kit to house those.
holes for the pots and push button are included in design but have not put holes for audio jack and CH340 USB which will vary depending on what one you have.

You will need:
Adafruit perma-proto 1/2 size
CH340G USB TTL Serial Adapter Ebay 162766671421
Arduino Uno FULL kit UK - Ebay 162597203220
