Transformer driver

[billybob]

I need a circuit that creates either a square wave, ramp, or whatever! Probably using the bare minimum parts necessary (preferably a few transistors) 9 volt minimum as input and two prong output.

unlike this circuit here.
Any help would be great thanks ( :

Assuming a "two prong output" means two outputs then wind the transformer with two secondaries.

BTW, if you want meaningful answers then you need to supply more information. I want a circuit doesn't really help.

Sorry, I was a little pre occupied. I mean a schematic that instead of base, collector, and the input positive to the transformer, its just the oscillating voltage (two wires). Sorry I don't know of any other way to say what I'm thinking. I'm still learning the definitions of electronic processes I'm 16.

I hope this helps with your question... Just no Ic

Have a read of This page. Something like fig1 may be what you need.

Thank you I will research more about the multivibrator.
