Arduino has just released an official ethernet shield. It’s based on the same WizNet W5100 chip that was used in the tiny ethernet board we covered earlier. The W5100 handles the full IP stack and can do TCP or UDP with four simultaneous sockets. The board has a power indicator plus six LEDs to debug the connection. It works with the standard ethernet library. The reset button resets the shield and the Arduino. The SD adapter is not currently supported by the Arduino software.

Gyro Controlled Game
[Eric] sent in this cool project that he did as part of his graduation project. He built a game that uses a gyroscope as an input device. For the gyroscope, he’s using a Powerball with a sensor inserted into it. This data is gathered by an Arduino in a pretty enclosure. The whole unit connects to a PC via USB and is supposedly plug and play. There’s a video of the setup in action on the site, just try not to laugh too hard watching them.
Arduino Wireless Rotating POV
[youtube=http://www.youtube.com/watch?v=7QMV4mRVpo4]
got an old cdrom and an Arduino laying around? Why not make it into a spinning POV display. It was built using parts from a floppy drive and a cdrom, as well as an Arduino and a small wireless transceiver. Using an IR sensor to detect rotations, the Arduino sends data to the LEDs. The wireless is used when sending new messages to the device. The link is in Spanish, so here’s the Google Translation.

LCD That Scans Fingerprints
AU Optronics Corp has unveiled a new LCD panel that doubles as a fingerprint scanner. Each pixel is equipped with 4 optical sensors, so a 320×240 screen would have a scanning resolution of 640×480. They have also experimented with different sensors, such as UV. You can see an LCD panel that detects and displays the UV index above. Why did they use a secondary display to show the data though?

Inductive Charging Going Mainstream
The recent announcement of Psyclone’s TouchCharge kit has us moderately excited. Though inductive charging has been used in electric toothbrushes for ages, we have yet to see it infiltrate the rest of our lives. The kit is a bit pricey at the moment, but it is a step in the right direction. Unfortunately, you have to have an adapter for your specific product and their selection is pretty limited right now. Why not make your own to power your devices? Warning: it is written from the perspective of [Arnold Schwarzanegger].
Update: Is the TouchCharge kit inductive? It appears to require contacts to touch the base.
Wooden Retro Keyboard Build
[phirzcol] sent us this cool step by step build of a retro looking keyboard, Inspired by [Von Slatt] and his work. [phirzcol] starts with a standard keyboard and removes the keys. He steams some wood to wrap the keyboard, then finishes it off nicely. The process of making the keys looks pretty grueling. Each key has 4 parts which have to be hand cut and assembled. A blue accent light is a nice touch as well. The keyboard looks pretty good, but we’d like to try typing on it for a while to see how usable it is. If it looks like too much effort, you can actually buy it on ebay.
BSoDomizer Blue-screens Your Enemies
In case you were wondering what industrious hacker [Joe Grand] was doing when he’s not building stuff for Prototype This!, designing Defcon badges, or testifying before congress, it’s this: The BSoDomizer is a VGA pass through device that displays an image of your choice on the victim’s screen. It can do this either periodically or via an IR trigger. The image of choice is a Windows style Blue Screen of Death. It’s powered by a watch battery. The project site has all the schematics you need plus ASCII goatse imagery; you’ve been warned. Embedded below is a demo of the device. We unfortunately didn’t get to see it when it was originally presented during Defcon 16. Continue reading “BSoDomizer Blue-screens Your Enemies”
