this is a little something i've been working on for the last week.
the rain in portland is out of control. i decided not to even bother with a paint job. instead i just used a kind of matching lego color scheme. in all, this only took about two and a half days to make. i probably could have finished it in one, but i didnt realize that until half way through the first day. the second day i was distracted by stuff thats not interesting. i finished it today in about 3 or 4 hours.
the circuit came from a toy keyboard/guitar convertible. you know, the one that looks like a guitar and then folds out in to a piano.
it had a few other functions on it but they sounded crappy to me. the toy its housed in is this little baby piano music box thing. i dont have a lot of pictures. this thing went pretty fast. but who cares what it used to look like anyway?
here is a functional diagram
here is the video that i thought was good until i uploaded it
