i would like to build a small simple synthesizer using 555 chips if possible. any oe haeve ideas or help?
i have a few 555 timers and have always wanted to build a sythesizer but i just don't know where to start. i have seen the optical theremin and the 555 metronome. i could add a pot instead of the photo transistor, and maybe connect the out put from the theremin to the metronome i would like some thing more like this ,http://hackaday.com/2009/08/28/xr-noise-box/ . i would like to kow if it is possible with 555 timers.
