[Gordon Johnson] sent in one of the odder active cooling mods I’ve seen. Initially he planned to use lots of pennies to create the heat pipe, but ended up using some copper pipe with some pennies tacked on to mate to the cpu. The pipe carries the cpu heat from the case into a… wine cooler. Judging from the size, I’d guess that the cooler is one of the peltier variety. To see the final creation, I had to go through the slide show youtube video.

Visual Computer Pong Player
I think it’d be more fun if the computer had to actuate a joystick, but [ashish]s visual based computer pong player is still pretty sweet. He’s capturing the game state with his webcam, and the computer processes the image and controls the pong paddle via tcp client connection based only on what it sees.
XT To AT Keyboard Adapter
If you dig the older switch based keyboards, you’ll like this. As a favor to a friend, [Bob van Loosen] built a small converter using a pic16F84 to make an XT telex keyboard usable with modern AT style computers.

Case Mod: The Dark Blade – Finally Finished
Case mods aren’t usually enough to make Hack-A-Day, but we all drooled a bit when the Dark Blade started back in 2004. Now, it’s finally finished. Everything on the case was custom machined just for this project. I cropped the base for the shot – check out the full pics in this thread. Thanks to [Jake] for the tip.
Serial Port Power Booster
This one(coral cache) is a bit of a head slapper, but I thought it might come in handy. Laptop (or usb) serial ports are pretty notorious for being stingy on power output. [Roberto] came up with a clever solution. He used a MAX205 (sort of a double+ MAX232) and a singe capacitor to convert the low power serial connection on his laptop to a TTL signal and back again to RS-232. The result is a simple dongle that needs 5v and gives you a high power serial port for those power hungry devices – like [Roberto]’s PIC programmer.
Bulletproof PC Case
Not our typical fare, but I can’t resist. [RCarter] is building a PC from scratch with a single unique feature – it’s designed to be bulletproof. Apparently, when it’s done he’s going to take it out back and teach it a lesson. Right now he’s more concerned with shock-proofing the hardware. Most people do this sort of thing at the end of the PC’s useful life.
