Here's a pretty crude drawing I made of the heating element. Starting with a 13mm OD tube, you wrap that with the NiCr wire coil. Then you put a silicone heat resistant O-ring around each end of it, and fit it inside of a 14mm ID tube so you have a nice seal and the wire won't be touching...

I found a Pyrex tube that has a 13mm OD and 1.2mm walls. I read that Pyrex has a low coefficient of thermal expansion, and especially when its only to ~400°F, I would think it wouldn't be an issue to wrap the NiCr wire around it. And would it be alright to just wind the NiCr wire around the...

Wow. That is incredibly helpful, thanks so much! I plan to use silver solder, and after doing some research it seems like I'll need to find some solder that's more than the standard amount of silver, maybe like 10% or so to get the melting point to where I want it do be. When you say we...

Whoa. That's a lot of terms that I don't understand. When I made some PCB kits before, I soldered each piece where it was supposed to go, but I have no idea what each one does. So I don't really understand what any of those things do. But as long as I know I need them, I probably don't need to...

I know how to solder and have made several kits using PCBs and stuff. I am confident I will be able to make this without personal or property damage. And as for the application, I am trying to make a vaporizer. So the airflow will be the speed of a very slow human breath.

Hello everybody, hopefully I am posting this in the right spot. What I am trying to do is design a heating element powered by a Li-Po battery (RC battery probably) to heat a heating element to a range of 360-420°F. I want the temp to be adjustable, probably on three settings, so one for 360...
