Today I tried mechanical pencil lead for diy soldering iron making. it gets heat very fast than normal graphite pencil lead. you try this idea. i used 5v dc 2apm mobile adapter as the power source. its worked properly. you can use it for basic soldering iron needs, such as wire joints, electrical wirings etc. however since the leakage of current it is not good for sensitive electronics soldering needs. take special care while working with electricity. if you are not familiar with electricity and and wiring do not try this as it can catch fire. author is not responsible for any damage or injury.
