Wonjae's disassembled the old plastic case recently and milled some MDF for a new housing. Yesterday and today I fixed some of the walls and today I tested it. Whatever problems were supposed to exist with the sound is nowhere to be found - it works fine. The mounting for the arduino needs to be fixed. The terminal strip needs to be mounted. All internal wiring needs to be clean up. A spring for one of the 4 speaker outputs from the amp fell out so the speaker is now using the other channel.
