My life is a lesson in self-discipline right now. Unfortunately, I'm a bad student! So, although you may think this post is about school, it is, instead, about what I do to avoid it (let's say relax after a long day!). I spend a lot of time in front of a computer running simulations, etc. I miss the hands-on aspects of engineering. That's what my evening activities provide! Here's my latest list of things I've fixed!
1) I noticed at work (they are remodeling) they were tossing some insulation. I've also noticed that at home, my room gets cold. What to do? Take the insulation home and put it above my bed!

Glad I did! Once I got up there, I noticed that there there was absolutely no insulation between three rafters directly above my bed! Problem solved!
Odd, it felt so much warmer that night!
2) Fixing 2 computers. It got me a great dinner with some great friends, but sometimes removing viruses can be time consuming! One computer was fixed with an online virus scan, but on the other I had to completely reinstall windows (and then everything else as well).
3) Fixed a friends printer. Somehow a tube had worked its way into the paper feed gearing and completely jammed it. I had to completely disassemble the printer to get it out. The fun part was that I actually put it back together correctly!
4) Repaired a closet door. It's one of those bifold, sliding doors. The wood is soft and the catches had broken through the wood, causing the rollers to not catch on the guide anymore. I rotated the entire door 180 degrees clockwise to use the holes on the other end, and it works great!
5) "Repaired" a furnace. Same friends had a problem - there furnace (gas) wouldn't ignite. After some playing around, I found the problem was that the insulation on the ignition wire had come off in a 2-inch length just before the pilot light. This wire ran close to the piping inside the furnace. Since that was closer than the pilot, the spark was shorting out to the furnace housing. I was thinking of just wrapping it in electrical tape. However, a quick test of the flammability of electrical tape convinced me that wouldn't be a good idea. Instead, I just tried to position the wire so that the path of least resistance was the pilot (just moved the wire as from from the sides as I could.
6) Fixed a friends wireless card. Two programs that controlled the wireless card were conflicting, but uninstalling one removed the driver, killing the network card. We didn't have the discs, and I couldn't download it anymore. Restored, downloaded the driver, re-unistalled (can you do that?) and then updated the driver. All good.
There might be a couple others, but that will work!
