Manufacturing circuit boards is not for the faint of heart, but a similar technique may soon be available to amateurs at home with the Lepen Soldering Pen. Moonhwan Lee has made the metalsmithing process a great deal less dangerous with this concept for a hi-tech alloy-melting utensil.
The device is modeled on the ballpoint pen, learning from the comfort and ergonomics of the everyday object, allowing for an implement which really requires maneuverability for accuracy. But much like a mechanical pencil, the wireless stylus is loaded with a stick of fusible lead. The Lepen Soldering Pen has been designed with buttons at its base, permitting the user to initiate the melting of the metal while he applies it precisely in place.
