[Adam] made a remote camera trigger that uses a laser. He had to install CHDK on his camera, which we’ve featured in a how-to, in order for it to work. CHDK allowed for a remote shutter trigger through the USB port. The laser bounces off a mirror and onto the photoresisitor hooked up to an Arduino. When the beam is broken, the Arduino sets off the trigger. He also plans to use the trigger to tweet over ethernet. Embedded is a video demonstrating its functionality.
The Camera Axe is an open source system for doing high speed camera triggering. You know all those pictures people get of balloons popping or drops of water in mid splash? This is how they do it. The system has light sensors and sound sensors to help get the timing just right. It can trigger your camera and the flash to capture images at just the right moment. There are a lot of picture examples on the site as well as a full schematic and parts list. Not too bad for roughly $100.
We recently posted a story about a 130 Megapixel camera made from a scanner. We’ve recently discovered a better view of the internals. While there aren’t a ton of details. This should be sufficient to get your own hacked together.

Made from a 1200 dpi epson scanner and a manual focus canon lens, this camera captures 130 Megapixel images. With a resolution of 13,068 x 10,173, these pictures are very detialed. You can see some examples in his flickr set. It doesn’t look like they’re the full size originals though. If you want to build your own, here’s a good start. Keep in mind that it’s from 2004 though.
[Mike] was going to be biking across Canada. He really wanted to document the trip, so he began planning ways to get still images taken at intervals along the way. After a bit of brainstorming, he ended up setting his goals a bit higher. He was going to film the entire trip. He really didn’t want a simple helmet cam, he wanted himself and the entire bike in the frame. To do this he had to build a long arm on which he mounted a bullet cam. On his handlebars, he has a simple control where he can turn the system on and off as well as initiate recording.
No single piece of this project was too complicated, but taken all together, the final result is quite nice. You can watch the video for yourself after the break.
[Soren Coughlin-Glaser] runs a mobile photobooth in the Portland area. It’s built inside of an electric Volkswagen bus. The conversion to electric hasn’t been easy though. He’s spent most of the last few months rebuilding it after an electrical fire. Last fall he installed a 9 inch electric motor from Hi-Torque Electric after his smaller one blew up. We really like this project and look forward to seeing it back on the road… once he replaces his stripped transmission coupler.

[Pete] has put together a fairly simple writeup on building a wireless USB tether for your DSLR. He’s basically using a pair of USB wireless adapters and a battery pack. In his original version, he did some slight modification to the dock that powers the USB dongle, adding his own battery pack too. He notes that this whole project can be done without the effort he put into it, at a little more expense. The only improvement we think would be nice would be a better way to package it to keep it out of the way while you shoot.
