STIR PLATE: I have a 3A rheostat, simple 12 v light up toggle switch, 5VDC cell phone charger, 12VDC pc fan, female disconnects, magnets from Hard drive.
1) My fan has 4 wires, white red black blue in that order). Any ideas? Just assume Red is hot, black is ground, and go with that?
2) is the 5VDC wall wort ample enough power?
1) I have an 18AWG power cord with ground from a computer. Can I use this for the fridge and heater or do I need a 14 or 12G or bigger?
18G is only 10A. I'm not trying to be cheap I'm fine with getting a 12 or 14G extension cord from home depot, but if I don't need to, I don't need to. Thanks!
