Jude Pullen created this cool solder buddy, which consists of a length of solder fed through an old brake cable by a servo. A button near the business end, with a Sugru grip, activates the servo by using the solder itself, as well as the metal windings of the brake cable to complete the circuit. Very sweet! [via Sugru.

    Very cool! It’s like a tiny version of my wire feed welder.

    Was hoping this was attached to the soldering iron for one-handed soldering but cool project none the less. Great construction!
