That's my pretentious attempt at doing something cool. An Arduino-based VCO. I made a quite imperfect resistor ladder DAC which got the bits wrong. So my sine wave ended up being not quite a sine wave. Which was more than ok for my purposes. The frequency response was also not quite 1 V/Oct (to say the least). This was also ok, since I used a Serge analog sequencer at the time. (Adjusting knobs, so the exact tracking didn't matter.) What I wanted to do next was a delay line, which failed because the Arduino kept crashing. Later I found out that the Arduino compiler doesn't do any checks whether you've allocated more memory than is available on the target, and that seems like the likely reason why I couldn't get it to work at the time. Now I feel inclined to try that again after a discussion on the SDIY mailing list.

That's the beauty of it:)

very nice triangle waves...
thanks!
I did one of those Auduinos about a year ago..I just followed instructions, but it was fun.
Next year when I finally have time, I'll build one of these and really try to do a nice case for it too (I'll replace the keyboard functions with some buttons, maybe):
yeah i was looking at that last night. i want to try and make some kind of sequencer, 8 or 16 step. i'm deciding what kind of features i'd want it to have now.

anyone else ever built stuff like this? what else have you done?
