My new toy: a powerbook tablet!

So I recently finished up my Powerbook Tablet project. This is such a momentous occasion that I think I will break my livejournal silence and add a post! :)

(I'll fill in more info in this post as I find the time)

Tools and Supplies (roughly)
Beloved 12" Powerbook G4... my first mac
Touchscreen tablet from Ebay: $50
Arctic silver CPU thermal paste
1 mini USB 2.0 A male to A female cable
Fine toothed hacksaw blade for metal cutting
Hammer + 1 nail
Tiny screwdriver set
   Double-sided tape
   Gray electrical tape
   Blue tape
   Anti-static tape (preferably, but not necessary...)
Aluminum foil
Metal file
Wet sanding block (hard foam), something like 220 grit will do
Soldering tools

This was actually easier than it seems. The blade cut through the aluminum like butter. Also, instead of sawing through the last edge, I scored it several times with a utility knife and bent it back and forth. It snaps off eventually, leaving a straight edge. :) I then applied a long piece of blue tape along the jagged edges and used it as a guide to straightened the cut out with a metal file. Lastly, the fine sand paper was used to smooth out the edges some more.

I found out that Nvidia cards in the powerbook models cannot do display rotation... This was annoying because the vent was facing toward me, blowing hot air out as I used the tablet. I ended up opening everything again to flip the actual display upside-down. The cable to the LCD's inverter board is really short, so it had to be made longer by soldering together an extension.

The USB cable that came with the touchscreen was replaced with one that is thinner and flatter so that it would lie behind the screen better. Unfortunately, it isn't shielded so the touchscreen didn't work at first. After proper shielding with some more handy aluminum foil, all is well. :)

"I looked up and saw a squirrel jump from one high tree to another. He appeared to be aiming for a limb so far out of reach that the leap looked like suicide. He missed, but landed, safe and unconcerned, on a branch several feet lower. Then he climbed to his goal, and all was well. "An old man sitting on the park bench said, 'Funny, I've seen hundreds of 'em jump like that, especially when there are dogs around and they can't come to the ground. A lot of 'em miss, but I've never seen any get hurt in trying.' Then he chuckled, 'I guess they've got to risk it if they don't want to spend their life in one tree.' I thought, 'A squirrel takes chances - have I less nerve than a squirrel?' Since then, whenever I have to choose between risking a new venture or hanging back, I hear the old man on the park bench saying, 'They've got to risk it if they don't want to spend their life in one tree.' So, I've jumped again and again. And in jumping I've learned why the squirrels so often do it; it's fun!"

Story time!

Ok I forgot to tell you guys a story...

So today I had to get books from the biomedical library - now moved down to bottom floor of Geisel library. The book was located in the middle of one of these "mobile" shelving units. Check out the animation at SpaceSaver.com to get an idea. I had a bad feeling about it from the moment I saw it....

I was looking for the book around the bottom shelves, so naturally I sat down to get a closer and more comfortable look. All of a sudden I hear metal clanking noise and one wall starts closing in on me. It was like Indiana Jones - Library book style!! The books were advancing, so I jumped up and tried to make a mad dash toward the end of the aisle. Unfortunately the aisle I made wasn't too wide to begin with so by the time I was running, I had to turn sideways and shuffle my self across instead. I decided to give up and said, "Stop squishing me!!"

Keep in mind that this was in a library.
