    Switch question

    That’s what I need. AC 220v. What’s it called? It’s hard find things like this here in the Philippines it seems.

    Nichrome wire help

    Ok, next question! I need to control the power going into the wire so that it gets hot enough but doesn't fry the wire. I tried a 100w 1.5R resistor 12v, but then it doesn't get hot enough. (no idea if that was a good idea or not). Would using a 4amp inline fuse do it instead of a resistor...

    Nichrome wire help

    Thanks, I am not cutting foam. I am making a mini electric blanket to fit around the fuel filter on my car. It's 4ft because its runs up and down a silicone sheet. So I need a step up transformer from 12v to 48v? You think that will work in this application?

    Nichrome wire help

    Thanks for the replies. Im back to the drawing board. Can anyone tell me what diameter Nichrome wire I need to reasonably heat 4ft of wire using a 12v car battery? Reasonable being anything between 100-250c. I don't need to be precise, and maths is wasted on me :) I don't know what size car...

    Nichrome wire help

    Hi So I put some 0.4mm (about 50cm) Nichrome wire across the two terminals of a car battery, thinking it would glow red, get hot etc. However, it mildly warmed and thats all. Am I missing something? I want to make a kind of heater with Nichrome inside silicone, but I don't understand why...
