[Shane ] sent in GATech’s senior design final projects, but his Autonomous single player foosball table is awesome. A Java app tracks player and ball via webcam. Then it acts as the opposite player by controlling servo actuated paddles. He’s copied his project to his personal server, just in case the class files get pulled next semester.
The course page is pretty ugly, but the project pages aren’t. It’s worth some time to check out the rest of the projects. The 2d iRobot based mapping system looks interesting, but lets be honest, the hand washing detector should be mandatory federal equipment at every fast food restaurant.

IPhone Serial Access Tutorial
[TheRain] sent in his tutorial on using the iPhone’s serial port. Apparently there’s a hardware trick required to enable two way communication. Whatever device is attached to the iPhone needs a secret handshake to get things talking both ways. Once the serial ground has been strobed high to low in the proper order, things will work like normal.
Hack-upgrade Your Magellan GPS
[dgoeken] sent in his Magellan 3100 hack. The device runs Windows CE 5.0, and mounts as a standard flash drive. Since everything is easily accessible, it’s just a matter of replacing and modifying the appropriate files. According to the GpsPassion message board, some are finding his guide useful for other models of Magellan GPS. So far he’s added a file manager, media player and upgraded the Points of Interest file. The site is slightly bandwidth challenged, so I’ve mirrored his hack process here.
Wiimote Projector Whiteboard
[Johnny Lee]’s back again with his Wiimote interactive whiteboard. Commercial versions of these things are expensive and heavy. His technique doesn’t even need a projector, just a computer, a Wiimote and a simple IR emitting pen. The pen is just a stylus with an infrared LED in the tip. Hit the video after the break, and you can grab the software from his site here.
Super8 Automatic Film Scanner
[edocronian] sent in this interesting mindstorm hack. [Harri] had several Super8 reels that he shot during the 80s. His kids put together this mindstorm NXT transport mechanism, and he did the rest with linux. The lego’s pull the reel across an Epson scanner, and some linux hacks run the scanner, identify the frames, and reconstruct the film. Unfortunately, [Harri] didn’t release any of the software hacks he used to pull it off.
Open An AXA Bike Lock With A Blank Key (Doh)
[Barry] sent in his writeup and video about a serious vulnerability in the AXA bike lock. (One of the most popular locks in the Netherlands.) It turns out that quite a few of them can be opened with a blank key. [Barry] demo’s the hack, and has some comments about the lame efforts of the manufacturer. If you enjoy interesting reading, check out his blog covering lock picking and physical security.
Obfuscate Your Power Switch
Just in time to keep your friends from sharing your toys, [l0rdnic0] brings you this simple mod: replace your power switch with a reed switch. Of course, now you’ll need a magnet every time you want to use your PSP. Of course, if my older brother did this, I’d build a big electromagnet and start firing it whenever he started playing games.
