This particular unit has been de-commissioned since 2005, but it’s still interesting. JACARA set up a webcam on Antarctica. They used an off the shelf Axis NetEye200 camera, mounted it inside a pair of hemispherical plastic domes along with a small electric heater and thermostat to keep the device from freezing.

Hack Cameras With The Image Fulgurator
[Wallace] sent in this awesome project built by [Julius Von Bismarck]. The “Image Fulgurator” is the result of mating an optical slave flash with a camera body turned projector. The result is the ability to project ghost images onto a picture being taken by anyone using a camera with their flash. Check out the demo video after the break or hit the project site for more.
On-board Focus Confirmation For The Canon Digital Rebel
We’ve seen plenty of lens hacks, but [Koray] took things in a new direction. Rather than buy lens chips for modding all of his manual lenses, he added a lens chip inside his Digital Rebel 300D (aka XT). Most of us might cringe at gutting their Rebel, but he performed this bit of soldering surgery on a unit he picked up for £40 and repaired. Excellent work!
Update: yeah yeah, the 300D is the original Digital Rebel.
Eye-Fi Explore Review

The WiFi uploading Eye-Fi SD card made a big splash when it was first introduced, but now Eye-Fi has a whole line of different products. The top of the line is the Eye-Fi Explore, which supports geotagging without using a GPS. Instead of GPS hardware, it uses the Skyhook Wireless Wi-Fi Postitioning System, which correlates the position of the Eye-Fi’s access point to GPS locations, creating virtual GPS functionality. This allows photos taken with the Eye-Fi to be be geotagged. Of course, the accuracy of the system is noticeably lower than true GPS and seems to be affected by a number of external factors, but it is still accurate enough to tag the photo within the immediate vicinity of where it was taken.
WiFi positioning is great feature, but certainly not limited to photography. Since the Eye-Fi is at its core SD storage media, you could probably have it geotag data saved to the card, even if it wasn’t created by a digital camera..
Mega Underwater DIY Video Housing
This fantastically huge housing was put together by [Ed Sauer]. He put it together using TIG welded 6061 aluminum for the body and machined the port mount out of 7075 aluminum. The lens port is a commercial unit from a housing manufacturer along with a few manual controls. He wrote up the build in this pdf.
Waterproof USB For Underwater Cameras
Underwater camera housings work great – but they are prone to humidity, dirt and dust problems if you open them more often than needed. In order to download the images off of his digital camera between dives, [Matt] decided to add a waterproof external USB port to his housing. He had an extra 5 pin strobe bulkhead installed by Ikelite (makers of excellent housings). Then he spliced on a mini-usb cable for the camera and spliced a standard USB end onto a strobe cable. During dives, the port is closed with an o-ring sealed cap.
Servo Focus And Aim Your Telescope
The idea of using servos to aim a telescope isn’t new, but [John]’s build looks so much like a prop from Johnny Mnemomic that we can’t resist posting it. The goal isn’t so much remote control as it is usability. He added a webcam and a pair of servos to help him fine focus and adjust the elevation of the scope to minimize vibration during those sensitive operations.
