Based on my analysis of your video your generator generates between 500Hz and 5000Hz

@henrykay01 Your trolling right? Please say yes. I want to believe you are simply a troll, hoping that some idiot will call and find out that their fridge is running.

If you have programming skills you can use your PC sound card to output audio waveforms of arbitrary complexity. Write .wav or .mp3 files filled with whatever data that you want (stereo or mono). Use FFTs to do show frequency spectrum displays, etc.

Transformers use AC or pulsed DC. It will shift / change the phase of the waveform. When fed back, it will cause oscillation. The core material and number of windings / wiring used will determine the usable frequency range.
USA wall outlet frequency xformers use 60 cycles per second (Hz), but audio xformers are used for isolation. RF transformers are used in cable TV splitters and obviously work on the old VHF and FM radio bands. You want DC, then you throw in a set of rectifiers.

A transformer takes high voltage input usually 240v ac and 'transforms' it to a lower voltage, maybe 12 or 9v.
What you're thinking of is a rectifier.

BTW, build a joule circuit, its a much cheaper way

hey nice video man. im a beginer in electronics but whats the role of the transformer there? i thought transformers where to transform form ac to dc am i right? thanks

Neat! Could you send me a schematic including the POT and x-former ratings? Any idea how high of a frequency it will produce? Thanks.
