[Jay] hacked a Blu-Ray laser diode into a keychain enclosure. He found a heavy brass keychain light from Lowe’s and stuffed the diode and a larger battery inside. The existing batteries weren’t powerful enough, so he drilled out the endcap to fit a 200mAh 3.6v lithium battery inside. He also modded the power button to only momentarily turn on the diode. With the larger battery, the laser can run for about an hour between charges. In addition to a Blu-Ray lasers, he also has versions with a 200mW red diode.

Bus Pirate Firmware Update V0g

buspiratefirmwarev0g

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.

Things To Hack: Sub 100$ Toy Night Vision, Projector, And Tv Game

projector

Ars Technica writes about three new toys coming out this year: a sub 100$ projector, tv game, and night vision goggles. The projector runs at standard TV resolution, takes standard composite in, and outputs an okay picture. The night vision goggles are monocular but focus both eyes on a single RGB LCD. The goggles uses an array of IR LEDs instead of amplifying ambient light to see in the dark. Lastly, they have a standalone implementation of the arcade game Big Game Hunters. The rifle uses a sensor bar to do the motion tracking and features a 32MB rom to hold the game files.

Reader [Bradley] sent in his ArduiNIX project, an Arduino shield designed for driving nixie tubes. The shield allows the Arduino to drive and multiplex nixie tubes without any additional hardware. These antique-looking displays are commonly hacked into clocks. It takes 9 volts from a wall wart and steps it up to over 200V in order to drive the displays. The shield is capable of multiplexing up to 80 individual elements. He has example code for driving a 6-digit display and a clock on his site. He is selling kits and completed shields too.

adafruit

Our friends over [adafruit] recently released the Sensor Pack 900, a collection of parts for anyone who is interested in using analog sensors with their projects. The pack includes 9 sensors. They range from simple thermistors and hall effect sensors to sharp distance sensors. Also included in the pack are 3 unidentified components that can be used to interface with the analog sensors in the pack. At only $30, the Sensor Pack 900 seems to offer a great set of introductory components for anyone prototyping a new device.

Reader, [Matthias_H], sent in a video about his USB adapter for SNES game carts. All you have to do is plug in the SNES game cartridge and USB cable, then a ROM file of the game shows up as an external storage device on your computer. After that, you can play the ROM with your choice of emulator. We emailed [Matthias] asking for more information, and he quickly replied with a very nice writeup about the hack that is pasted below.

Update: [Matthias] launched a site for the “snega2usb” with updates on the development of the board and a FAQ.

IPhone 3G S Teardown

Already, both Rapid repair and ifixit have torn down the new iPhone 3G S, and phonewreck has provided some analysis. The new CPU runs twice as fast at 600 MHz and supports 720p video. They also found that the new 3 megapixel camera took better photos. Surprisingly, despite apple’s claims that the new phone has significantly better battery life, the battery itself has only 6% more capacity. Overall, not much has changed.
