    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.

    Ok, thanks. Means I will need to order some more silicone sheet and more wire but sounds like the only way to go.

    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 for the thoughts all. Yes, it is for a biodiesel situation. The length I have used is 4ft sandwhiched and glued between two thin sheets of silicone. I never thought of using parallel lengths. It is actually quite tricky to run the nichrome wire up and down and glue it! I poked nails...

    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...

    Nichrome wire heating project. help please!

    I use methanol a lot, and its really nasty stuff. I think they use it in racing cars. I always imagine cars blowing up!

    Nichrome wire heating project. help please!

    I have started making Biodiesel as a bit of a hobby with a money saving edge. When the engine is warm the car runs perfectly. But on a cold winter morning you have to have pretty robust battery not to go flat before it starts. Biodidesel is thicker than normal diesel and thickens even more...

    Nichrome wire heating project. help please!

    Awesome, thanks. In terms of the Atom bomb the UK government would probably let it past customs without batting an eye lid. a thermostatic switch could be a bit harder.

    Nichrome wire heating project. help please!

    I presume you mean the temperature of the filter not the wire? Sorry if thats a dumb question.

    Nichrome wire heating project. help please!

    Thanks you have been very helpful. Could I ask one other thing? Could you give me a link to the actual sensor on that website? I can't find it on there. Many thanks.
