Shake phone to start it.  Simultaneously outputs a square wave, triangle wave, and crude sine wave.  First part is a schmitt trigger, then integrator, and wave shaper. For more info google these.  Sine wave could be cleaner with more diodes but theres only so much space in sim.  You can also modify the frequency by changing the 10k resistor. Hope you enjoy the signal generator.

Shoot, you've got plenty space left over- go for the gusto!..

Ok made some adjustments to the diodes and resistors. The sine wave should be a lot smoother now

How to get this circuit Doing what it is supposed to?

Ok! Found Out about this... Anyway, I think it's stupid to shake my iPad...I simply added a tap switch, a source and a Resistance and the Oscie starts comfortably!!!!! Insane Jerks!

Ok ill try that. I believe the real circuit begins oscillating because there is always some noise to trigger it. The sim only adds noise from shaking but i can add a switch as another option for starting the oscillation

Ok added a button switch to the original circuit to begin the oscillation. Just tap it or shake your phone to start the circuit

Also you guys may have notice one benifit of this circuit is that it can oscillate slower than an ac source from the sim and it is also independent of the circuit time rate
