Cold Fire You Can Touch - DIY Cold Plasma Torch (Patreon)
Content
Plasma is the 4th state of matter and it comes in many flavors. You probably know it from it's greatest hits, fire and lightning, but there is a lot more to plasma than most people are aware of. Cold plasma is my personal favorite as it has the same beautiful glow that all plasma has, but it's no warmer than room temp and feels cold to the touch. In this video we go through my year long journey to harness this weird state of matter into a torch that can be used for future experiments and in the lab.
I didn't really go to much into just how long of a project this was in the video, but thought I'd share a bit of extra background here. This project started almost as soon as I got to montreal last year. Myself and a friend have been trying to get this working in various forms but only recently had any success that allowed us to build this torch. We first tried several variations of building a microwave emmitter that would make the plasma, but that refused to work. We tried several other potential power sources, and eventually we found the power supply in the video, and it moved more quickly from there.
There really were at least 18 prototypes, though honestly we think we lost a few and the number may be higher. The capillaries come in a pack of 500 and we went through at least a 5th of the tube, so ~100 capillaries. For various versions it required that I cut the capillaries to length which took a while to figure out. But the final version uses full length capillaries to avoid having to do that nonsense as it's an awful process.
All in all, I learned so much from this project and my lathe skills got a serious work out. Hope you all enjoy!
