Arduino Nano Granular drone synth (Krustpunkhippy)

I bought some PCBs from Krustpunkhippy ( ) , this is the first I've built . It was a really easy solder. I'm a novice at this stuff and I wasn't sure what pots to solder on - I used 10k ones; other arduino designs seem to use 5k. Ah well, it works! I did a dodgy socketing job so I can lift out the Nano if I want; I could solder the nano to the board I guess (not sure about doing that yet, though, they're expensive!) The jack socket is just floating on some wires so it's a bit crackly. I'm astonished this worked, like I say, I'm a novice! The software uses the Mozzi library None of this is “my work“ except the soldering/assembly!
