I made an Atari Punk Console for fiddling around at jams, and managed to find a sweet miniature candy lunchbox to use as an enclosure.
I did the PCB using a stripboard, which turned out to be pretty easy once the layout was designed. I put together a schematic in DIY Layout Creator. See the attachment below - you can download this layout as a DIY file if you decide to build an APC using this style of PCB and you want to save a little time!
