minus-square@yucandu@lemmy.worldlinkfedilinkEnglish28•edit-23 months agoI used to make shunt resistors out of a pencil and a piece of paper. Rub pencil all over paper, cut strips to size of required resistance. EDIT: I mean megaohm resistors not shunt resistors. 20MOhm for DIY theramin.

I admire it but also…wtf lol
