The boards for the second prototype arrived a couple days ago. Very exciting. I have unpacked a set and taken the picture below. The top board is the camera board. The left board contains the amplifiers and the right board is the brains. I have tried to fit the boards into the new prototype case and there are a few 'boo-boos' but nothing we can't fix. Mostly the problems are in the height of the boards. In a couple of cases, I failed to leave enough room for the connectors to clear the walls of the case.
Next task is to get the boards booting and see if I can make some music. Keep your fingers crossed!
