oscillator circuit ?

[nitinnun]

how do i configure an oscillator circuit,
to turn a source of DC electricity (9 volt battery?),
into AC electricity ?


if ever i needed a straight forward answer, it is on how to do this.
preferably step by step.


don't tell me to go to google.
google is 2 steps above useless, for things like this.

don't send me to a website with endless blah blah not-what-i-need.
each word that i read, tortures the nerves in my right brain matter.

just say it.

This is the circuit I used to generate a sinewave.

Connect the output of this circuit to the load, and the other side of the load to ground.

I needed mo amps, so I build a bridge amplifier to boost the output...

You can look at the schematic and the bridge amplifier here...

So why ya playing with AC now?  Gonna catch a wave?

more like i'm going to kick a magnetic field in the teeth, with frequency.

*wink* *wink*



i also read that high frequency magnetic fields, make people feel better.
and even heal them of injury and disease.

How clean a sine, or is square OK? 
How much output? 
Would a 555 timer do?
What Frequency Range? 
Adjustable? 
Stability?  (Just for a couple hints....)
[ also, a good suggestion is quality vs component count, expense, etc.. ]

i doubt it matters if it is sine or square.

i doubt it matters how dirty the signal is, either.

if you showed a 30 volt output at half an amp, i could adjust that, to whatever i wanted.

the frequency doesn't have to be adjustable.

couldn't i avoid an IC chip, by connecting together a bunch of transistors?
the more transistors, the more oscillations, the higher the frequency?

i wanted to try 120 hertz,
180 hertz,
240 hertz,
300 hertz,
and 360 hertz.
any of those, would be fine.

stability doesn't matter much.
i can worry about stablity, after i get a prototype working.


minimum components,
at minimum cost,
are important.

i want it to be as simple/cheap as possible, while still working.

I  have not made  one yet but I have been planning  a similar  project .

I was  going to make an oscillator using  an LC resonant circuit  driven by a PWM ( pulse  width modulator )
I had links  for  how to make these things but lost them when I had to reformat my hard drive a month ago .
I remember that  a datasheet  on  a 555 timer showed how to make  a  PWM and other devices with a 555chip

They say that  a LC circuit  will ring when  hit  with  a  pulse of energy .
I planned to hit  it with a pulse from the PWM once each cycle .

The  voltage used could be  anything that  a 555 chip can handle ......
