Hey everyone, I'm new to the site, and I need a little help. I'm working on a small invention that has proven to be a little more complicated than I thought. I wont go into too many details about what it is because I'm keeping it a secret until I can get a working prototype out.
What I'm basically making is a device that uses 2 nichrome heating coils that are 33mm in diameret, burning at 445C. My temperature readings aren't too accurate yet, because I'm stuck using the thermometer on my voltage meter until my IR one comes in. Depending on where I go with my design, the temperature of these coils may go down to about 290C.
I would like to install a devise kind of like what is in a hair dryer, because there will be air flowing through this thing, and I would like the coils to maintain a constant temperature. I have no idea what this devise would be called (other than a thermostat) or how to build one.
I also have no idea how to build the power supply for this thing, because so far using a 120V power supply salvaged from an old Iron has vaporized the nichrome wire I salvaged out of a toaster.
Any help anyone could provide would be awesome. I will update this with more details as soon as I figure them out.
