SUPER SIMPLE OSCILLATOR

 
 

SUPER SIMPLE DIY OSCILLATOR YOU CAN MAKE IN 10 MINUTES. SUPER CHEAP AND EASY. 

So this is strange because your using a transistor in a way it isnt intended for, REVERSE AVALANCHE MODE is the name, OSCILLATING is its game!

This is based off a circuit i used in this video, which is making a light theremin out of a red bull can, no solder either!

Heres an updated schematic with a tone/filter knob!! you can put multiple oscillators before the filter!

for info check this video! and below is the SCHEM and STRIPBOARD LAYOUT. 

***MAKE SURE YOU CUT OFF THE CENTRE LEG OF THE TRANSISTOR OR IT WONT WORK*

TRY different Transistors. check out this great link (CLICK) on reverse avalanche. he talks about different transistors he has tried, the one that caught my eye and i may have to try is SS9018 as it only needs 8 volts insteat of the aboves 12 volts!!! so im going to give this a go also.

 

Play around with capacitor values. the larger the capacitor the slower it will oscillate.. and the higher.... it will be all high pitched! in the red bull can video! i used a 220nf capacitor! so it was a high synth. like a theremin. But in the video above i wanted it to be low and angry so i put a 10uf on it.
