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

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):

very nice triangle waves...
thanks!

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.

Very cool stuff!
Ya I guess when making this kind of thing, the practical applications always creep into he back of your mind. A stepper would be awesome.

i can only make ultra generic beats or weird noise nonsense with an analog sequencer, but dont allow me to discourage you, those things are fun to play with and im certainly not saying that if i cant use one good no one can.

That's the beauty of it:)

I've not done anything with the arduino yet, but I've messed around with CMOS synths/noisemakers. Like some NAND droners, heterodyne space exploerer, etc. So much fun, if you haven't you should try it, the chips are extremely cheap (4903 is around 25-50 cents, 40106 the same). Search Lunetta forum if you want more info.

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.
