My battery powered mechanical lamp is bust. One of the conductive plating is corroded. I was wondering if I can replace it with flimsy (bare) steel and a coil from a pen soldered on the wire?
The easiest thing to do is clean up the corrosion with some sandpaper or other abrasive and then rub a little oil on it to help stop it corroding again. If it happens again just repeat the process.
The corroded piece. Is it fixable (maybe through some kind of anti-corrosion bath)? Or should I try and build it myself? Or just buy I completely new lamp?
