/diy/ - Do It Yourself

Hello /ohm/

I'm looking to create a lissajous pattern generator as my electronics class final project. I acquired a Tek 485 scope from a garbage bin this summer and thought this would be interesting. Overall design I think is going to be two frequency variable sine wave generators, one differentiated to get a cosine. Possibly with some extra stuff to add phase offsets...

Anyways I'm kinda overwhelmed with all of the sine oscillators on the internet. Nothing seems to be quite the right balance of low enough distortion, low enough price, and low enough complexity. Leaning towards a fancy Wien bridge design like pic related.

tl,dr: analog, sine wave, audio frequency, variable frequency, not too high distortion oscillator designs.
