Two things that i've thought of doing, but i'm out of enclosures at the moment (Thanks to Banzai! Anyone had any troubles with them the last month by the way??).
First, to mount the PCB or stripboard directly on the back of the pots(put some tape or something in between of course) would save space, and make it rigid too.
Number two, i've got the idea of using magnets to hold batteries instead of battery holders. Great idea,whoever came up with it! I was thinking of doing this with boards too, then you easily take them out again for modding. For example, glue a magnet on the bottom of the enclosure and one on the board. How does that sound?
