Wireless headphones can be a wonderful way to help clear up the clutter inherent in most desktop PC systems. However, after plugging a wall wart in, and the headphone jack into the computer, the number of wires used has actually doubled. After [Parker] found an old set of JVC 900 Mhz wireless headphones (and a generic 900MHz transmitter), he cracked open the case to see what he could do with them. Realizing that the transmitter used a 12V DC source, he powered it with an unused floppy connector (which provides +12V, +5V, and two ground lines). He also wired…

Pong on your wrist
[John] wanted to take a pong clock and put it in a wristwatch form factor. Take an afternoon and pour over his detailed build logs. This multi-year project is done with meticulous cleanliness that makes us jealous. He’s milled the case and buttons himself, achieving a professional look that equals or surpasses the quality of some commercially available “gaming” watches. The project centers around an OLED display driven by a TI MSP430F2013 processor. Don’t miss the video after the break covering prototyping, PCB work, case milling, and the watch in action. Currently, this is the third generation of development…

Capacitive buttons control all life
Projects involving Conway’s Game of Life and utilizing a Nokia 3310 screen are quite popular with electronics hobbyists. [Droky] put these two together and went one step further by adding capacitive sensors to control the Game of Life. His work is a great example of how to use the Atmel QTouch capacitive sensor (QT100a datasheet). This chip does the heavy lifting that we’ve seen in other touch sensitive solutions. It operates from 2V-5.5V, requires only three capacitors and a resistor, has a one pin active high output, and sells for around $1 in low quantities. One thing [Droky] overlooked…

Open Source Weapon Makes You Puke
[Limor] of Adafruit Industries and the Ice Tube Clock has made her own open source non-lethal weapon: The Bedazzler. After attending a conference by the DHS where she saw the big-budget Dazzler, she decided to make her own. Thirty-six LEDs, six switching FETs, a Boarduino, and a former flashlight later, the Bedazzler makes a better rave toy than a weapon. It doesn’t work as-is, but we figure it will only be a matter of time before someone hacks this to make people… umm hack. See the video after the break.

Radio controlled beetle flight footage
Earlier this year we were amazed when University of California researchers controlled a beetle via electrical implants. The video available at the time of the original report showed beetles tethered in place while electrical stimuli was applied via the chip. New video of free flight is has now been posted. Although the motion is rather sporadic, it is obvious that simple commands to start flight, stop flight, and turn left or right are having their intended effect. Check out this cyborg action after the break. Is DARPA one step closer to unleashing legions of insect warriors on unsuspecting masses?…

Ben Heck gets sloppy and we love it
[Ben Heck] is a name synonymous with game system hacking. His projects have been seen and praised by people all over the world for both their quality and their ingenuity. He’s so good, in fact, that many of his projects have gone far beyond what we typically think of as hacking. They look and feel like commercial products. While that is a fantastic accomplishment, we have a soft spot for seeing stuff that is truly hacked. This lasted job he did is a great example. The controller needed to work using a single hand, so he hacked it. He was in a…

New Wii drive hardware emulation
The Wii-Optical-Drive-Emulator (WODE) makes it possible to load Wii and GameCube ISO files from an SD card or USB storage device. This hack uses the ribbon cable for the optical drive to connect to the Wii, requiring no soldering. The WODE is based on an ARM9 processor, runs Linux, and features a backlit LCD screen and 4-way center click joystick. Storage can be hot plugged and then an ISO selected using the stick and LCD display. Selected ISO files appear in the game channel as if an original disc had just been inserted into the drive.

BlokClok – Abstract time display
Clocks made from blinking LEDs always make for fun projects. [Earthshine] built a clock that displays time abstractly using an 8×8 RGB LED matrix. The video embedded after the break illustrates how to read the time but here’s the gist of it: One LED is illuminated in the outside box of LEDs and moved in a clockwise motion to approximate seconds. Inside of this, there are four quadrants; upper left indicates hour-tens digit, upper right hour-ones, lower left minute-tens, and lower right minute-ones. This certainly makes for an interesting conversation piece!
There is no schematic and no code available…

Eee PC NAS
Hack a Day reader [The_Glu] shared with us a project of his. He used an Eee PC 701 he had lying around with a broken LCD, along with three 1TB SATA drives to create a custom NAS server for his house. The server features a number of other interesting components, including USB2SATA converters to connect the hard drives, as well as a 2 line LCD to display RAID information and server status. The entire project is wrapped up in a custom made Plexiglas enclosure with case fans to keep the whole thing cool. While this may not be the first…

High altitude balloons
We received quite a bit of tips, after posting about the 150$ high altitude balloon project, from communities and teams who had done similar tasks. There is more to these projects than simply filling a balloon and attaching a camera, so in order to allow everyone their 7 seconds of well deserved fame, we’ve compiled a quick list of similar high altitude balloons. Catch it after the break.
Do note, these are in no order or rank.
RPI Electronics club, sent in their Imaging Balloon of Science. Supposedly built in under 30 hours and runs Linux.

iPhone cop-cam
[Tim] wanted to make some recordings of himself driving similar to those made by the dashboard cameras on police cars. In a simple two step hack (1. Measure, 2. Drill), he altered his iPhone windshield mount so that it didn’t block the lens of the camera. We will admit (sheepishly) that at first glance we thought this might be connected to the outside of the windshield but it’s not. Take a look at his drive to work after the break.
