I got my start in programming with Lemonade Stand on a Commodore PET. (No, I don't remember the model) A little manual reading taught me LIST, and soon thereafter I discovered that people will pay a huge amount of money for Lemonade if it's 10000 degrees outside.
I've used portmon from http://www.sysinternals.com/ to do some of this. They also have a nice registry and file monitor, along with lots of other great NT and 95/98 tools. Some of them even include source.
Actually, the hopefully soon to be launched Phase3D Amateur Radio satellite uses 3 flywheel like devices (they call them reaction or momentum wheels) to allow the satellite to stay oriented properly in 3d space. Check out http://www.amsat.org/ and http://myweb.magicnet.net/~phase3d/newpics/solar .html (They've got lots of good technical info on how they solved lots of the technical aspects of keeping a satellite up... Even heat dissapation is complicated without air.)
It's cold outside, there's no kind of atmosphere I'm all alone, more or less Let me fly far away from here Fun, fun, fun in the sun, sun, sun
I want to lie shipwrecked and comatose Drinking fresh mango juice Goldfish shoals nibbling at my toes Fun, fun, fun in the sun, sun, sun Fun, fun, fun in the sun, sun, sun
I think you'll find that coke cans are not designed with robotic opener friendlyness as a concern. Using something to pierce 2 holes is probably alot easier than pulling the tab...
More on topic, I found a nifty site at http://www.lynxmotion.com/ But it's not really cheap.. This one is cheaper, and has source for their control software on their page: http://www.imagesco.com/catalog/RoboticArm/Robot icArm01.html
I found lots more by feeding http://www.google.com/ "robot arm kit"

Back in college we used a big GMF robot to flatten cans. A huge 8 foot tall 6 axis robot is a bit overkill for this task... One day someone set an incorrect path, and before they could hit the e-stop, it moved a 1 ton CNC lathe several feet across the floor...
What alot of us forget, is that Windows 95 defaults to not showing the extension for files it knows the type of. So if you name a file NIFTY_PICTURE.GIF.VBS, alot of non technical people will see it as NIFTY_PICTURE.GIF. But when they double click it, it runs... (Win98 may default to this too, I don't remember)
I suspect lots of nongeeks leave it at the default...
2.0.37? I've got one machine that's still running 1.2.13! It just keeps running, and it's not directly on the net so I don't have to worry about remote crashes... It's hit 365 days uptime twice in the 4 years it's been around, and would have gone longer if it weren't for UPS maint and server room rearranging... Too bad I can't find a copy of SLS... I want to try running it in vmware to try to remember what it was like when I started long ago with 0.99pl5.
Minor problem... We don't use dots up here where it snows. The snow plows would eat them. (Or the salt.)
Besides, I like driving. I've been known to just pick a direction, and drive that way for a while. Of course, this is much more fun when you're driving a fun car, like a 944TS.:)
I use a similar hosts file, and I setup apache using a rewrite rule to send back a 1x1 transparent gif file for any requests. I have it send a tiny html file for any requests for asp/htm/html files to avoid problems with frames and such.
It'd be possible to have it not rewrite if it was pointing to one of your real pages.
I just havn't gotten around to setting up junkbuster, because this works so well. (And most of the time from home I browse with images off, which helps alot)
Fans don't help in space, as there's no air to move heat. Instead of convection, in space you have to use conduction (think big heat sink connected to the outside of the spacecraft) and radiation (to radiate the heat into space).
The special hardware is to deal with cosmic radiation, which can cause errors in memory and processors, and eventually cause them to fail.
For a lot of info about satellites, check out http://www.amsat.org/ which has information about Amateur Radio satellites, including some nice diagrams and explanations of how stuff works. Especially recommended is http://www.amsat.org/amsat/sats/phase3d.html which has lots of links to detailed descriptions of things like reaction wheels and magnetorquers.
Tweaking Lemonade Stand on a PET in 5th grade is what got me started programming. People will pay alot of money for lemonade when it's 10000 degrees out. Although, the Apple II's were fun... We used to do things like take the floppies and controller cards from several, and make 1 with 8 floppy drives on it... Remember the koala pads? Flight Simulator on a green screen....
Why should you have to pay sales/use taxes on a used car? (which we do here in Michigan at 6%) Since the first owner already paid, and the second owner paid, and the third owner paid... I think they make lots of money on this deal... So if a car sells new for 18k, then 10k, then 5k, then 2k, the state gets: $1080+$600+$300+$120=$2100, plus license plate, title transfer, and registration fees... (and gas taxes...)
Cheap boards. I've got expensive ISA boards that you can have 20 of them share 1 IRQ if you've got the slots for them. (Dialogic computer telephony boards). The boards have to tristate the interrupt instead of pulling it up/down when they're not using it.
I found a nice small keyboard, that I use for some of our rack mounted gear. It's only 12" wide. My only complaint is that the arrow keys are a bit weird. It fits nicely into the keyboard tray in the rack, and there's enough room left over next to it for the mouse, so I don't have to use the mouse tray.

LOGO is a nice language to learn. All the turtle commands are fairly easy to see results from. I remember writing a simple paint program that used a touch pad on an apple IIe in a few hours...
My favorite test is to pan the CD to one side, and the the wave output to the other, and then play the CD and MP3 at the same time (takes a bit of practice). With headphones, it's then really easy to hear the difference. Although, after I encoded, and noticed a noise in the MP3, I listened to the WAV, and it had it too... Blah..
It's also possible to modify the executable directly, without having the source. The people that crack copy protection do this all the time... Having the source at least lets you build your own known good version...
For better traction, find a purely optical mouse/trackball. I've used one of the logitech trackballs that has a big red ball, and it's purely optical, no moving parts other than the ball itself.
Myself, I like Pegasus. It supports IMAP, and with plugins, supports PGP. QDPGP is one of several plugins that add PGP support. It adds signing/encrypting/decrypting/key management abilities to Pegasus. Pegasus has nifty mail filtering abilities also.
