[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.

[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 see it completed.

Those brainy folks over at Stanford are working on an open source digital camera. This is an effort to advance what they call “computational photography”. Basically they’re looking to combine some of the functionality of Photoshop or Gimp right into the camera. One example they discuss is utilizing an algorithm to even out the light levels from one side of the picture to the other. Another trick they’ve already accomplished in the lab is increasing the resolution of full motion video. They take a full resolution photo once every few frames and use the computing power of the camera to incorporate that information into the low-res frames around it.

We like the idea of being able to get at the firmware that runs on our digital cameras. Going with open source would certainly provide that access, but cost will be an issue. The Stanford team hopes to produce a model of what they now call Frankencamera that sells for “less than $1000″.

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.

Next week, August 31 through September 4, is Ubuntu Developer Week. If you’ve always wanted to help out with an open source project but didn’t know how to get into it, this is your chance. The week consists of 25 one-hour sessions held interactively through IRC and led by some of the best of the Ubuntu development team. Participate in as many or as few sessions as you want. Check out the Ubuntu Developer Week page or their fancy brochure (PDF) for more information.

Want to see what it’s all about before committing to a live session? You can view the IRC logs from the January sessions. In addition to ‘Getting Started’, you may find the ‘Packaging 101′ and ‘Launchpad Bug Tracking’ session notes interesting.

SparkFun has started to release some of their kits as open-source hardware. Projects such as ClockIt, a simple alarm clock, have their schematics, board designs, and source code released under the CC-by-sa license. Although most of their widgets and projects already had example code and schematics available, they are now using an open-source license. They are joining adafruit and EMSL and others in pushing OSH, but it is interesting to see an established company turn to this. Normally, startups do this to encourage early adoption.

Firmware v0g for all Bus Pirate revisions is now available. Updates in this release include a bootloader, frequency generator/pulse-width modulator, SPI bus sniffer, MIDI library, configuration reports, improved user interface, and bug fixes. v0g is also the first firmware to fully support the v2 hardware branch.

We’re really proud of this release as it brings a much more consistent structure to the internal operation of the Bus Pirate. It lays the foundation for future CAN, LIN, and OBDII libraries, and it supports localization and translations.  Install and upgrade instructions are included with the firmware. Report bugs on the project issue tracker.

We document the new features after the break.

We’re putting a bounty on two high-priority Bus Pirate features. You can get a free PCB for the upcoming Bus Pirate V2 by writing a bit of code. Hack a Day has a varied and talented group of readers, and we know someone out there has the experience to make these changes with minimal difficulty.

• The latest code integrates the PIC24F bootloader for easy updates without a programmer. We’d like to add a protocol snooper, but that requires interrupts. With the bootloader, however, interrupts are relocated and we’ve yet to fully grasp how that works. We’ll send a PCB and PIC 24F to the first person who modifies the code to demonstrate UART, SPI, or change notification interrupts with the boot loader. Microchip’s 24F bootloader app note is available here. Complete.

• The current frequency measurement feature is a hack that uses a counter and a timer. Be the first to implement the input capture peripheral instead, and get a free PCB. See the function bpFreq(void) in base.c. Complete.

The latest Bus Pirate code and compiled firmware can be checked-out from Google Code SVN. Submit your code via the comments below or buspirate@hackaday.com.

UPDATE: Both issues were resolved. Thanks for your suggestions.

Evil Mad Scientist Laboratories have just announced the release of the Meggy Jr RGB, a fully programmable handheld console with an 8×8 RGB LED matrix display. Like its big sisters Peggy and Peggy 2.0, the Meggy Jr is driven by an ATmega168 microcontroller and is made up of a bank of fully addressable LEDs. Unlike its siblings, the device boasts six buttons and the ability to be mounted inside of a custom case (or “handle set”) constructed from plastic or wood, drastically altering the look of the console. Using the popular open-souce Arduino environment, users are able to write custom software for the device. While it works great as a game console, of the many possible configurations and suggested uses, we think “disco floor for your Lego minifigurines” is the most amusing.

Technology Review turns the spotlight on the open source hardware movement. Open source hardware is hardly a new concept, but lately it’s been getting a lot more attention, with the help of magazines like MAKE and websites like Instructables. Chumby, a company that sells a modifiable cube with a screen, embedded computer, and a Wi-Fi connection, designed their product to be easily hackable. The openness of the product caused a community heavily invested in the product’s development to be created. The growth of such communities has also sparked interest from corporations such as Nokia, which is collaborating with MIT on open source video decoders. They recognized that opening up would cause development time to be reduced and provide greater flexibility, allowing them to allocate resources to other areas, including marketing and brand development. [Jamey Hicks], director of the Nokia Research Center in Cambridge, believes that the open source movement can even complement closed designs, as long as it’s handled appropriately. With greater access to sophisticated software tools and resources, the barriers to entry keep falling away, and it’s much easier for the world to discover the joys of tinkering and hacking.
