Notorious hacker conference Defcon has just published their Call for Papers. The 17th annual event will happen July 30th through August 2nd. Most of the announcement is the same boilerplate they’ve included for the past two years. Like last year, they’re not defining the specific speaking track themes and will come up with them based on submissions. New for this year is a half-day of workshops on the Thursday before Defcon for anyone that’s showing up early. This pre-con event is targeted at newbies. It certainly sounds like an interesting way to ease into Defcon instead of the usual delays and fire marshals. We’ve been attending every year since 2005 and love seeing new things. You should definitely consider presenting this year (we want to see more hardware!).
This surprisingly pleasant looking crib is actually a robot, designed to keep babies quiet and happy all night long. Once inside and locked up, the baby is under the robot’s care. When the robot senses crying, it rocks gently back and forth. This should allow parents the time to catch some sleep. As pointed out in the article, the $5000 price tag is a bit steep. Especially considering the fact that you can get a much less technologically advanced equivalent for relatively cheap. How many of you hackers have babies? What hacks did you do to get your babies to sleep?
Linear Technology’s LTC2631A-LZ8 is an 8bit digital to analog converter (DAC) with an I2C interface. This DAC can output 255 different voltages, spaced evenly between 0 and 2.5volts. We previously demonstrated the LTC2640 with a three-wire SPI interface, but this version is controlled with only two signal wires.

Scientists at the university of California have managed to implant a chip in a giant flower beetle that makes it respond to commands from the computer. They can tell it to fly, stop, turn left and turn right. The controls are done through its optic nerves and wing muscles. Though the article states that flight signals are sent to the optic lobes and steering is done through stimulation of the wing muscles, the video shows steering being accomplished through optic lobe stimulation.
Though we’re sure there’s some grand scientific goal behind this, we can’t help but think (hope) that we’ll be seeing giant robot controlled beetle battles with lasers and rockets.
For those of you who don’t recall, the Wiremap is a 3d volumetric display built from hundreds of tiny strands. An image is projected onto the strands to achieve 3d effects. [phedhex] has posted an in depth instructable on how to build a wiremap. He covers the construction with lots of good tips as well as giving links to the software for Windows, Mac, and Linux. Check out the video after te break to see some fairly impressive 3d patterns.
