DIY resistor from broken soldering iron

Nichrome (NiCr, nickel-chrome, chrome-nickel, etc.) generally refers to any alloy of nickel, chromium, and often iron and/or other elements or substances. Nichrome alloys are typically used in resistance wire. They are also used in some dental restorations (fillings) and in other applications.

Tools:

• soldering Iron
• Digital Multimeter

Materials:

• nichrome wire from broken soldering iron
• 2 x i inch stainless paper clips (cut it)
• Plaster of Paris
• small tube for mold

First is to measure the ohm value you want then cut the nichrome wire and solder it to the ends of the two stainless so it will be like:

Insert it to the tube centering it with a hard paper with a hole to let through the stainless wire. it will look like this:

The last step is to pour your Plaster of Paris into the mold covering the wires completely and leave it to dry.
