Know anyone that's into gaming? Modding old consoles is a great way to get into diagnosing board problems and fixing the crap PCBs in small electronics is fantastic for learning to solder. Two weeks ago I didn't know shit about the eldrich slab of charms and runes inside electronics. Last week I successfully tested two power units for a playstation 4 and correctly diagnosed that mine has died due to APU overheating. Took about 2 hours, two videos, and a $15 continuity tester.

Unfortunately, mine's dead in the water until I find someone who can reball the APU for less than the cost of a new system. In the mean time, I'm doing a tear down and mod on my Xbox 360.
