I wanted to make a sine wave oscillator but I obtained this.
Please comment if you can help me.

That is a sine wave niki, just a little clamped off the down end

Yes but I want to make a great sine wave and not that strange thing

How perfect should the sinwave be? THD?

10% 5% 2% 1% 0.5% 0.2% or even 0.1%?

As perfect as possible

Take your PC install SW e.g. audacity and generate a sinewave track of any frequency from 20 to 20kHz. Another way is a wien bridge osillator which is not easy to build http://everycircuit.com/circuit/5397492826898432

pls change all the base resistors to 4.5k,and all the capacitors to 5mF.Then watch.If you can't wait time,shake your device.try it ,niki.bye

your oscillator is really good I like it.I have seen it just now,not one before

Wow it works thank you :)

This look like around 5% THD which is not to bad, but far away from perfect ;p

Yes, but it's perfect for my uses

Ok, but the only open question now for me is, for what do you need this ugly sinewave and why wasn't the waveform before not good enough for your purpose?

Because I'm building a laser oscilloscope and I need something to test it
