zero tension unwinder 🧘‍♂️

Building an EDM ?

not this time but as soon as I have found a new ground floor reps labs HQ

do you need a spark generator

thank you 🤩 EDM is definitely still on the long TODO list but this is for precision wirewound resistors, those wouldn't appreciate sparks

alright sounds good. open offer so lmk

Wonder if something like this is used to unspool low tc resistance wire for wirewounds. Not sure how much of an effect the mechanical stresses of unspooling the wire would be but surely its enough to warrant at least consideration for the highest performance resistors.

that is exactly what I made this for 🤓

Should have looked at the label on the spool, now that I see it, it looks like Molecuwire. Did you ever figure out a way to reliability weld NiCr alloys to copper?

This reminds me of devices to unspool bond wires. Thin stick out of some plastic, a light sensor and gravity.

gulty 🫡that's where I stole the idea

What is this bouncy TO220 doing?

what will you use it for?
