Power resistor DIY
This is one simple way to create power resistor at home.
I needed 0,33 ohm resistor with some larger wattage so I decide to create one, instead of buying one.
I always say, creating is much more fun then buying.
So you need one old high wattage resistor ( I had one 10W 100 ohm ) to use wire from it.You will have to destroy it, and take high resisting wire of desired length-resistance.
You also need some copper wire as connectors.
And you will need jointing filler to create mass for coating, to protect resistor wire from oxidation, and to provide heat transfer from wire to environment.
Also you will need small piece of tin to create mold.
After finishing it will take some day or two to dry
