clone of 'minimo' programmable device
mmo is a fairly faithful recreation of the open-source minimo except for the adition of a buffered output and the use of the ubiquitous ICSP programming header seen in many other boards.
In order to update the firmware, you will need a suitable programmer — something like the USBAsp is great — it's what I use. See Programming ICSP Modules on the wonkystuff website.
miniMo came up in discussion on the AE Modular Forum, and it looked like a fun thing to make a version of.
wonkystuff already make a programmable module based on the ATTiny85, but in case that takes up too much space in the rack, or you don't actually need to reprogram using an audio signal, then the mmo might be for you!
As might be expected, connectivity is limited!
John from wonkystuff® made a pair of videos on the wonkystuff® YouTube channel describing the PCB layout of the mmo, as a beginners guide to future module builders:
