How To: Fix Dead Lithium-Ion Batteries That Won't Hold a Charge Anymore
"What is dead may never die." That's easily one of the best lines (and episode title) from HBO's Game of Thrones series. While the saying may ring true for the Ironborn, it's not quite as catchy when it comes to batteries.

How To: Quick-N-Dirty Circuit Board Repair: How to Patch Faded or Corroded Traces with Pencil Lead
You may already know that you can build a functional circuit on a sheet of paper with the graphite from a pencil, but you'd probably never think of using it to fix an electronic device. This same principle can be used to bring back a bricked phone, but can also repair a damaged or corroded trace in a printed circuit board.

Got a knack for speeding? Like running red lights? Believe or not, the police have better things to be doing than pulling you over, like catching real criminals.

How To: Zap and revive old NiCad batteries with a mig welder
Nicad batteries often die in such a way that they won't take a charge and have zero voltage. This usually means they're shorted out by crystal dendrite growth. Here's a method of bringing them back to life by zapping those shorted crystal dendrites away with too much current and/or voltage. We'll use a welder as a power source. You could also use a car battery, a DC powersupply, or almost anything with some voltage. Charged-up capacitors are popular for this because you can get a very fast pu...
