[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.

[Chris] liked Cartesian RepRap idea so much that he decided to design his master’s diploma project around it. Though it uses most of the same parts as the RepRap (even the PCBs), [Chris] has adapted it so it does milling rather than 3D printing.  Most of the parts (such as the stepper motors) were harvested from old inkjet printers and typewriters. The thee-axis CNC machine can already etch and carve styrofoam at an impressively high resolution. To deal with all of the debris that comes with milling, a vacuum attachment (shown attached) was created. [Chris] is considering adapting it so it can work with wood and aluminum…

Ever wanted to be able to launch a balloon into space, track its location via GPS, take some photographs of the curvature of the earth, and recover the balloon, all for the low low cost of $150? [Oliver Yeh] sent in his teams project, Icarus, which does just that. The group of MIT students found that they could use a weather balloon filled with helium to reach heights of around 20 miles above the earth;  their particular balloon achieved 93,000 feet (17.5 miles). Then, utilizing only off the shelf components with no soldering, conjured up a GPS tracker using…

[Kevin] sent in his almost finished open source dot matrix clock. Sporting a hefty 40 x 16 display powered by a PIC 18F he has complete pixel by pixel control of the graphics. Combined with with a triple buffer he is at least able to output 15fps, with planned 30fps. While this has great potential for a clock, what about going further? Twitter updates, chat messages, weather updates, the current airspeed velocity of an unladen swallow; it will be tough to beat the competition without some more features. Either way, its an awesome project and we can’t wait to…

BrewTroller is an open source brewing control system based on the Sanguino. Targeting home beer brewers, this project gathers some of the best features from other DIY brewing controllers and packages them into a hardware and software setup so it’s accessible to those without the skills to design their own. It can interface with 4 heat controllers, 32 pumps/valves, 6 temperature sensors, 3 volume sensors, and 1 steam pressure sensor. The system displays information through a 4 line LCD. It can be used to monitor and maintain temperature during mashing, boiling, and chilling. If you have a more advanced…

Starfish PBX takes the very popular Asterisk telephony platform and adds an open source, fully functional web management interface. Asterisk allows you to be your own private branch exchange; think of it as your own telephone company. You can setup extensions in your home or office, configure an intercom system, implement a hold system with music, manage voice mail, and integrate Voice over Internet Protocol. Starfish PBX, available in alpha release today, aims to make Asterisk available to a wider user base by simplifying the interface used to setup and maintain the system.

When [Jespersaur] purchased a Luxeed LED keyboard, he was disappointed to find that the drivers were not open source and didn’t support all the features he wanted. His solution? Hack the drivers that come with it, and implement his own. In his article, he gives a basic rundown of beginning reverse engineering by multiple methods and a brief introduction to libusb. For the Linux drivers, check out [Kurt Stephens]’s site, where he supplies a link to the source code, instructions on building it, and a tutorial on sending commands to the keyboard.

This is the Illuminato X Machina, a “cellular” style computing system.  Each unit is a fully functioning computer with its own processor, storage and communications.  You can watch above as a change in the operating software is propagated across the grid. You can see the LEDs in the video going nuts, there are actually LEDs on the sides too. [Justin] described it to us as a personal fireworks show on your desk.  This system is fully open with the schematics and source code available on their site. You might recognize these guys too, we covered their Open Source GameBoy.
