Electronics Repair

Knowing how to repair things is one of the more important tools a prepared person can have. While increased miniaturization and performance of electronics has resulted in many devices being cheaper to replace rather than repair, there’s quite a few things which one can do to keep ones electronics in top shape while also saving a bunch of money.
Take, for example, my Garmin StreetPilot c330 GPS unit. It’s served me well over the last three years, though after enduring a blazing Arizona summer (or two), the internal lithium-ion battery was no longer able to hold a charge.
Garmin wanted $150 for an out-of-warranty replacement of the battery, which I thought was a bit hefty, so I did a bit of research online. It turns out that the battery was an “18650” lithium-ion battery, which is available at a number of retailers, including the local BatteriesPlus store. Fortunately, the local shop also had a model (PDA-210LI) of the battery which included the necessary plug to fit the circuit board of the GPS unit. While it was a bit pricier than the bare battery, it made life quite a bit easier.
Installation was rather easy: I simply needed to de-solder where the wires from the original plug (which was permanently connected to the battery) connected to the internal speakers and solder the speaker wires from the new plug to those same points. After that, it was a trivial matter of plugging the battery in and closing everything up. The battery charged up as expected and runs the GPS just fine.
This particular problem was quite simple and required only the most basic knowledge of soldering, but it ended up saving me $120. Oftentimes problems found with electronic devices are fairly simple (blown fuses, dead batteries, worn-out wire, etc.) and can be repaired using inexpensive, off-the-shelf tools (e.g. a soldering iron) and basic knowledge.
In addition to saving money, knowledge of basic electronics (and their repair) can be quite fun.
