cotdt Posted April 30, 2007 Report Share Posted April 30, 2007 How would you make your own resistor of any arbitrary value? What natural material works well? I've made my own inductors out of tin foil, then capacitors out of mineral oil, and would like to move on to resistors. Any advice would be grateful.

cotdt Posted May 1, 2007 Author Report Share Posted May 1, 2007 I should note that the resistor should be durable and reliable. Quote Link to comment Share on other sites More sharing options...
aerius Posted May 1, 2007 Report Share Posted May 1, 2007 Find some Nichrome wire. Measure its resistance for a given length. Then cut a length equal to the resistance value needed and wrap it around a dowel or cardboard tube. Dip the whole thing in epoxy. There's your resistor.

cotdt Posted May 2, 2007 Author Report Share Posted May 2, 2007 Those wires tend to be 20ohms per feet, which is useful, but not universal. I use a lot of 10K resistors. In that case, what should I use? Quote Link to comment Share on other sites More sharing options...
