Hello,

I have a buck boost, here is what I have, http://www.ebay.com/itm/282411084410? I use it for electrolysis project, however I want to experiment with different wave forms (Sine Square Sawtooth), . I was looking at wave generators on ebay but I wasn't sure if I can hook them up to my buck boost. I'm using about 20-38 volts and 1-10 milliamp for the electrolysis. I'm on a budget up to $50, I don't have any fancy equipment like oscillators and such, i'm pretty much a noob on this stuff. Thank you for your future help.

 

You could get yourself an old (ie free) audio amplifier and feed it tones from a smartphone app signal generator.

I don’t see a role for a DC-DC converter in supplying an AC waveform.
