Make your own laptop

[Richard] pointed out this mini-itx laptop. The idea behind this particular design is to enable upgrading every component as needed. The case is aluminum, and the wiring inside is an exercise in patience. It’s not the first DIY laptop we’ve seen, and it doesn’t have batteries, but it’s the first I’ve seen with two internal hard drives.

Update: There is a battery, it just gets very little mention. It’s hiding under the DVD drive and one of the hard drives. Anyone know what kind it is?

Ben Heck’s Wii laptop on Engadget

[Ben Heckendorn] put together this little beauty on engadget. It’s not quite as over the top as the XBox 360 laptop, but there’s a reason for that. He’ll be putting up a How-To series covering the construction. If you’ve been pondering building a portable yourself, it’ll be a nice jump start for your hardware hacking skill-base.

PS3 DVR How-To

If you glanced at the PS3 and thought it was too expensive, this might help you justify spending your green. [ken_vs_ryu] put up a mini tutorial on running mythtv under Linux on the PS3 with an external USB capture device. When you consider the cost of a decent machine, video card and blue-ray drive, it’s not a bad deal. (I’m not sure how many Plextor ConvertX encoders you can run at once.) To get things working, you’ll have to thumb through the Gentoo Wiki for the details on setting up the ConvertX.

Interactive pillow

[nicolas büchi] sent in his groups latest project at Zurich University. This innocent pillow interacts with the user based on current light conditions and proximity sensing(pressure). The project pages are in German, but the video demonstration explains it. I like the idea of a vibrating pillow alarm clock – as long as you don’t loose it during the night. It reminds me of Clocky – which is actually for sale now.

WL-700gE Serial Port mod

The Asus WL-700gE is an interesting device. It provides NAS, streaming and routing services thanks to linux. In their quest to modify the WL-700gE to a more flexible platform, [Eric] documented adding a serial port to its not so spacious innards. (FYI, Standard serial/RS-232 signals are around 5 volts ok, more like 12. I was thinking of the max 232/n variety) Asus was kind enough to provide through hole mounts and a TTL interface right on the board with console access already turned on.

I hadn’t realized it before, but the Siemens phone USB data cable is a nice cheap source of USB to TTL serial interfaces. Ironically, replacing the cable on the data unit was actually more difficult than adding the port to the router.

Digital Rebel XT(350D) IR removal

[ash] wasn’t satisfied with these instructions, so he provided a complete how-to on gutting a Rebel XT to remove the glass IR filter. This one involves pulling everything down to the CCD. Once the IR glass is removed, it’s replaced with some high grade glass from Edmund Optics. If you’re into camera modding at all, and own a Digital Rebel, the reference links at the end of the how-to are worth a read.

Lazy psp player (automatic woodchopper)

[Andrew]‘s love hate relationship with his PSP is impressive. He used a webcam to watch for the appearance of the woodblock and used a small motor (probably serial or parallel actuated) to trigger the button on command. It’s a little silly, but it’s a good exercise for computer visual interaction.
