My build in progress:

Already have ICs, but need some resistors and pots. Hope to get them by the next week.
And this is a $5 keyboard, which I’m going to convert to MIDI controller to drive the meeblip:

I’ve already compiled the .asm file and programmeed it into atmega. Led lights up.
Update: Initially I was to order all those exotic resistors, but eventually got too impatient and made them all of more common values.
E.g. the 23k7 is two 47k in parallel. 274 = 220+47+10
Now I hooked it up and are playing without pots, just switches. When I touch pot lines with my fingers it bleeps.
So far the sound seems very nice!
