DIY Chumby HACK - How to hack a 640Ă—480 VGA LCD onto a Chumby!
Here’s a really cool Chumby hack that will allow you to use a bigger 640×480 pixel LCD on your favorite little gadget.
Chumby is different; it is open source, and designed to be hacked. For example, the serial port is spelled out on the silkscreen for you and there’s a backdoor to enable sshd, so it’s not big deal to bring up the console. Because of its hackability, you are enabled to do significant modifications due to the availability of all levels of design documentation—hardware, drivers, and application software. While it would be an enormous task to, for example, open up a Zune and put a larger screen on it, here, in this post, I will show you how to hack a chumby to have a larger, higher-resolution screen without too much effort. The native chumby screen is a 3.5” QVGA (320×240) display, but after you complete this hack, you will be treated to a 5.7” VGA (640×480) display.

Furniture from Factory Waste!
Here’s a great way to exemplify how factory waste should be converted into artistic furniture.
Wood waste and off-cuts were collected from factories in Denmark, this collection is made entirely out of the factory waste collected. The pieces were put together to form a wood patchwork before they were made into; a chair, a book box and a series of 12 lamps.

Eee PC Hack - How to Hack your Internal Devices on an ASUS Eee PC!
Here’s a great wiki site showing you good information on how to hack the ASUS Eee PC including how to add a GPS unit without breaking your arm off.
There are several points on the motherboard where power can be draw, for devices requiring 3.3v or 5v. Ground is universal and allows for short wire runs. A diagram over the points can be found on the research page.
The signal wires thickness is 30 AWG and 24 AWG for the power and ground wires. The wire type is called wire wrap and used for prototyping and repair work. Mine is Tefzel insulated and made by Habia Cable. Some of the devices are held in place by double-sided 1 mm thick foam tape. To cover up and prevent shorts I used 3M Kapton 10 mm wide tape.

Concept Throwing Camera that can capture those random Pics!
Here’s a funny throwing camera that will capture pictures at set intervals on its way down. This seems like an excellent way to capture some random images from slightly above ground level.
The Flee Digital Camera is designed specifically to take photos after you’ve launched it into the air. The casing for the camera actually looks like it was inspired by some of the fancier balls made for playing fetch with your dog.
The Flee is bluetooth enabled and will transmit the photos it takes directly to your cellphone. No word on the size and quality of the pictures or on what the usable range away from the cellphone is.
DIY - How to Build a Hard Disk Green Laser Projector!
Here’s a really cool DIY showing you how to build a hard disk laser scanner made from bunch of old hard disks.
My latest tinkery hardware and embedded systems project is a homebrew laser scanner. You know, the kind you see at planetariums- sweep a laser beam around on the wall really fast, and draw vector graphics. Commercial laser scanners have been around for decades now, but buying a complete system is still really pricy, even on eBay. Besides, where’s the fun in that?
There are plenty of examples of homebrew laser scanners on the internet. Many people have wired up a pair of loudspeakers, hard disk actuators, or other readily available mechanisms to an amplifier and used them for simple laser graphics. This will make some pretty wiggly patterns on the wall, but it isn’t a real vector graphics display. The best example I know of for a totally built-from-scratch laser projector (not using commercial galvo actuators) actually uses custom hand-wound galvanometers. Very nice.
