What are you making ⚒️ / 3D printing 🖨

I wonder if anyone has looked into using electrolysis to pull carbon off a suppressor…. That is a whole niche into itself…

Random electronics questions for 3D printer modding

Can you get led ribbon in 24v? It looks like it, but I just want to make sure the ribbon is actually 24v and it isn’t just a 12v ribbon with a step down converter

I want a litte 24v led light smack dab on print head underside, and printer is 24v and I’d rather keep
Voltage native if possible

Second question, can I install a potentiometer or a rheostat (I can’t remember the difference at the moment) in series with a led ribbon to vary brightness? I keep seeing stuff about needing various resistors and my caveman with a soldering iron brain doesn’t get it
