Edit: Brevity! I got this mini locking pliers (Vise-Grip knockoffs) at Lowe's for $2. It is awesome. I keep it with me all the time. It's saved my ass on more than one occasion, and I haven't had it more than 2 months. Highly recommended. The End.

Off Topic: Power supply fire
A little over a year ago, Amanda bought a new Dell Studio desktop. During an electrical storm recently, it awoke from standby and started smelling of burning electronics. This smell woke Amanda up (it was the middle of the night), and she, naturally, woke me up. She had tracked the smell down to her computer by this point, and noted that one of the fans was running loudly.
I opened the thing up so I could tell Amanda something comforting and go back to sleep. I made sure important components weren't actually on fire.
The smell dissipated by morning and her computer was still working, though it would regularly hang for a few moments, the power supply fan would kick on high speed, and it would then it would continue working.
The following evening I opened up the power supply and found these things:
Burn marks on the board (center, dark brown spot), and...
capacitors and other components showing signs of overheating. The capacitors are swollen, though that's hard to tell here. That small ring with the wire coiled around it and the cracking white stuff is called a choke, and, as I suspected, is used for reducing electrical noise/interference. I didn't know what it was until I went looking on the magical interwebs. The white stuff is not supposed to be flaking off like that.
I don't know what, exactly, sprayed onto the heatsink (large aluminum block) like that. Anyway, all these stressed components resulted in the power supply working inefficiently and causing the fan to kick on whenever you demanded processing power from the computer.
I found a replacement among mine and my dad's pile of computer parts. All is well.

Pocket multi-tools actually ARE useful
I changed the fuel filter on the ZX2 today, using nothing more than this, a Leatherman knockoff using the Columbia name. I did this on my lunch break. It took no longer than it would have with the proper tool(s): about 10 minutes, including hand-washing. All I would've needed was a flathead screwdriver, and my tool has one. Sort of. It did the job, anyway.
On a related note, I've discovered that my skin doesn't really like gasoline. It turns red and blotchy where I come in contact with the stuff.
Pardon the shitty photo. I don't think my cell phone camera focuses at less than a few feet.

Timing Belt Blues
This was the tensioner spring for the timing belt on Amanda's new car. Look closely at the clip on the right. Scary, huh? That's crazy worn out. It's also stretched beyond spec: the spring coils should be touching each other.
With 90k miles, the timing belt had not yet been replaced on her new 2000 Protege ES*. This is a 100k mile service in California (with inspections every 30k); a 60k mile service everywhere else**. So it was due. In ordering the parts, I neglected to order a new tensioner spring. It's only $3. To get it locally, however, it costs $90, and you can only get it with the two pulleys. Circumstances being what they were, Amanda had to buy the $90 set.
Next time, I will know. And so will you, dear reader who happens to own a Mazda product with this type of spring tensioner, and happens to replace his/her own timing belts, and is expecting to do so soon.
You can get this spring at RockAuto.com. If you work at RockAuto, please send me free stuff. I need to fix a lot of stuff. Come on, what's a Miata steering rack between friends? We are friends, right? Right? ....
______________________________
*Pedantic aside: that's the F-series 1.8L engine, the same family used in forthcoming Proteges; the 1.6L engine was a B-series, related to the Miata and Protege engines of previous years, and also the Ford Escort GT.
**I'm sure this has to do with California laws more than engineering.
