LFO Expression Pedal

Def checkout the Madbean pedals Tappy project, it can output VCO, resistive, and optical control

Saw the tappy, uses the ic of electricdruid. Again it would be costly for me. Trust me, getting even a pencil from outside of Turkey costs shtload of taxes on customs. So i need to solve this with parts that i can find within the country borders..

So.. What should I do?

Make a simple timer circuit from NE555, or go digital with digipots and such.

Assuming that I've made an LFO circuit, how should be the TRS connections then?
