Apropos of nothing, but I started a project just over a year ago to get back to my embedded-programming roots Somewhat inspired by devices by Bastl et. al. I started having fun with an ATTiny85. One of the groups I am in make music only with instruments that we have made ourselves, so this was another reason for embarking on this.
I find it fun to go really low-level: no DSP here! 8k code space, 512 bytes RAM and 6 usable I/O pins
First build (bad video):
Small demo (not much better video):
and a slightly better video of one or two of them in a gig context:
I have been producing small runs of kits sold locally, and I have some other projects on the go as well. Would be interested in finding like-minded people I guess
