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.

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?

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.
[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.
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”
Now that we listen to MP3s, and watch XVIDs or x264s, a computer is the entertainment center in at least one room of most homes. Unless you have a special HTPC, though, you’re probably stuck using the keyboard to pause, change the volume, and fast-forward through annoying Mythbusters recaps. PC remote control receivers range from ancient serial port designs (who has one?) to USB devices not supported by popular software. In this how-to we design a USB infrared receiver that imitates a common protocol supported by software for Windows, Linux, and Mac. We’ve got a full guide to the protocol plus schematics and a parts list.
Here’s a fun little suprise that showed up in a recent Flaming Lips interview. Frontman Wayne Coyne built this custom guitar rig out of a double-necked Epiphone. It has a neck from a Guitar Hero controller, which triggers a built in KORG Kaossilator touchpad synthesizer. Checkout the video interview at around 1:55 for a demo. He went with the Guitar Hero controller because he feels that it’s replacing regular guitars in childrens’ perception of how guitar is played.
