Hi,
There is so much information on sustainers and they seem really complex to make. However, it seems like it should be really, really to do with an arduino. Maybe I am just missing something (in which case please fill me in!), but why can't we just pipe the audio signal into an arduino's analog pins, and then write 5 lines of code that will convert said input into something that powers the driver? Instead of futzing around with all of the hardware, we should (again, unless I am guilty of confusion of concepts) be able to just connect guitar output to arduino to driver.
So far I have experimented with just programming my board to make 2-5 millisecond pulses, which go through an extra gibson pickup I have and essentially what I get is a radio. If I hold that arduino powered pickup over the guitar's pickup, my test tone gets played through the amp. My guess is that the output from the board is a bit underpowered.
So I guess my questions are:
1. Am I wasting my time with an arduino-based sustainer?
*advantages would seem to be super cheap, like ten bucks, super simple (minimal circuitry needed), and infinitely programatically customizable.
Arduino Controled Diy Sustainer

Thanks, Prostheta. I was def thinking of using the arduino to control transistors, which would be hooked up to whatever else. I guess I thought with so many DIY arduino stomp boxes that can handle signal processing, why not a sustainer, but I def don't know the details so it is entirely possible that it wouldn't be able to handle it.
I actually just hooked the arduino up to a transistor, which controlled a 9v's input into an old stock gibson SG pickup and set the on off time between 1ms to 7ms. I put a razor blade next to it and was able to feel the vibrations. So then I aimed the pickup at a guitar I had lying around. Unfortunately, there was a ton of interference that drown out any noise I could here. Though, and this could be my hopeful imagination, but I think I felt a couple of the strings vibrating. Barely, but I am pretty sure they were.
My next step will be to just put more power through the pickup to see if I can increase the effect on the guitar. If that fails, I guess I will either have to make a real driver or give up b/c of lack of time; unless there are some totally obvious mistakes I am making?
Thanks for reading!
