This isn’t a brand new hack, but it’s a great solution for most digital cameras that like to go to sleep on you.
[T. Black] put together a nice simple pic circuit to control a cheap aiptek digital camera. It uses a 12C508, a cap and a resistor. The PIC not only activates the shutter, but can wake up the camera from sleep mode. You don’t even have to provide a dedicated control channel – it can piggy-back on the throttle control signal. The hardest part of the project is tapping the signals on the SMD pc board inside the camera. There have been quite a few R/C camera controllers built, but this is certainly one of the most elegant. You can grab the code and schematic from the bottom of the project page.

GPS Enabled Radar Database
The page pretty much lacks every possible detail, but [Mattias] put together his own RADAR camera notification. It uses a published database of camera’s and a GPS receiver to notify the driver that they’re approaching one of the many permanent speed detection cameras in Sweden. Despite the lack of details, I can guess about the design. It shouldn’t be that difficult to construct something similar with a PIC or AVR with a decent amount of memory. Just compare the current location with the list, and notify the driver when it determines that it’s within a specified distance. Unfortunately all the RADAR detectors where I live are strapped to police cars.
Laser Dance Pad
[A. Smyth] passed this along – it’s another take on the non-mechanical dance pad. The first prototype used IR detection, but apparently the hardware was flaky. The new version uses cheap laser pointer style diodes with photo detectors. Personally, I want to see one that breaks the laser into a line and collimates the resulting beam, and senses beam interference by measuring the intensity. (And it would look incredible with a fogger) The electronics are pretty simple – the photocells are interfaced with the guts of a USB game pad and breaking the beam creates a button push.
Industrial Alarm Clock
While clocky runs away from you, this alarm clock can probably strike back. It’s got a pair of basic stamps along with relay’s to control external devices. [Jason] built it from parts he already had, and has visions of it being used for stage fx control later on. For now, I’ll bet that none of the guests will want to attempt turning it off for fear of reprisal by the clock.
Defcon Bot Challenge Prototype
[Colin] sent in his prototype for the Defcon bot contest. The performance of the bot in the video is impressive. Hit it after the break. His build looks clean and simple – he even managed to score some sponsorship in the form of pololu servo controllers. Targeting the moving white sensor reminds me of the old MacGuyver episode with the lethal heat seeking robots.
If you’re working on any attack bots, feel free to let us know via the tips line.
Update: I woke up to realize that I forgot to embed the video. It should work now.
