So what am I missing here? I wanted to make a better tool other than my solder gun

so I took a coil off a 19 inch double it up wrapped it with electrical tape added a power cord to it.

While it didn't blow a fuse immediately when I plugged it it it was smoking in seconds and super hot!!

How to make one that works like the coils they sell? Do I need a resistor in there?

I am still smelling the magical smell of burnt electronics.... I threw the coil on the basement floor cause that sucker was hot!!

Put a light in-line as seen here. That's what I did. Works well.

That looks so dangerous

Make sure you insulate that switch real good, there may be active / live power right there.

I am a sparky, and I just picked up a top of the line degausser yesterday for about $95.00

I just hate the thought of a fire or electric shock

Please be careful guys

A 19" set is a bit small. I always try to use one from a 25" or larger. The larger the screen, the longer the coil, and the longer you can have it plugged in before it gets too hot to hold.

It WILL get hot in a few seconds. It's essentially a modified short across the line. In service, there's a thermistor in series that only pulses it for a half second.

You should only plug your coil in for five seconds or so, that's all you need. It will get very hot, and if you leave it plugged in too long, it will smoke.

Fun stuff!
 
The degaussing ring I used the other day had a momentary switch built into it, so you could leave it plugged in while you were using it, and just hit the momentary switch to actually activate it. And it didn't take very long for it to get warm if I held the switch on.

Yeah, any degaussing coil is going to get hot while you're using it, even a commercial one. They're meant for very short usage, and you need to let it cool down between uses.

When making your own coil, sometimes it's difficult to find a momentary switch that will handle the current draw of the coil, I usually just use a regular cord and plug/unplug it, or use a power strip with a switch on it.

I've got one I made with a switch, and like four or five without - mainly because I can never seem to find a coil when I need one, but I've got enough junk to build another one. One of these days I'm going to thoroughly clean my basement, and I'm going to find a bunch of degaussing coils, #2 phillips head screwdrivers, null modem cables, and all those other things I keep needing/using and misplacing.

When you have machines next to each other I would assume you need to mve the one you are going to degauss first?

No. Sometimes the field will affect the neighboring monitors, but I've not had any problems where I messed up the other monitors. They'll wobble a bit, but the degaussing coil isn't going to magnetize them or anything. You'll only magnetize a monitor with a degaussing coil if you shut it off while close to the screen. You need to start away from the tube a few feet, turn on the coil, move in, make smooth movements around the tube, move back out, and shut it off when you get three or four feet away.

Thanks! Have you ever worked on a tube projection TV?
