[Will] submitted his ski goggle mod. He has mounted an Oregon Scientific ATC3K digicam in his goggles. This should make recording ski trips a lot easier. Most of the electronics fit just fine in the mask, though he did need to use an IDE cable to extend parts of it to the custom pack mounted on the strap. We’re also curious how much wind noise he’s going to get on that microphone.
[Matthew] sent us his group’s final project, where they built a nice GPS logging system. Not only can it simply log the GPS coordinates on a predetermined interval, it can also be triggered to make an entry by a wireless device. In this example, they use a camera. This allows them to then upload all the GPS information and pictures to places like Google Earth.
They are using an ATmega644, with an LCD, SD card, and GPS unit. They had to do a little hacking on their camera to add the wireless transmitter, which triggers the logger. You can see not only the cost break down and source code for the project, but also a map with lots of geotagged photos. This is the kind of thing we can almost see as a standard item in the future.
Here’s a great example of a cheap mod that gets professional results. This ring flash cost roughly $14 all together, and they got to eat some fruit salad in the process. The parts list is pretty easy and can almost be figured out just by looking at the picture. A plastic bowl, an aluminum can, some foil, and a lens adapter. This is very nice and much easier than our last ring light post.
GNUCITIZEN has posted information on linksys wireless IP camera hacking. It turns out that some models send the administrator user name and password to the computer when the setup wizard requests a connection. In theory, someone could send the request and harvest your passwords wirelessly. This seems like a pretty careless oversight. We would think that linksys will probably remedy this before too long.

[Daniel] sent us his entry to the Epilog laser cutter challenge on instructables. He made a book scanner, mainly out of found parts. The bulk of the project was salvaged from dumpsters, though if you’re not comfortable with that, the free section of craigslist might be able to do the job. The cameras are loaded with CHDK, using StereoData maker, and custom software to compile the images into PDFs. They did a fantastic job of documenting every step of the construction, including helpful tips for some of the more complicated parts. There are several videos in the instructable, so be sure to check them out. We’re particularly amused by the extra step of making the photo captions visually interesting. At 79 steps, it’s a long read, but well worth it.
[Tim] photographs insects for bugguide.net. As you can imagine, macro photography is a must. He was very frustrated with his camera’s stock ability to capture the insects. You can see in the example on his site that the image is blurry and has some color issues. He did some research and hacked together a method of getting fantastic macro images for relatively cheap. He used the reversed lens method to get his macro lens set up. He then modded his camera with CHDK for more control. He found that his focal distance was too small to get the entire bug in focus, so he took 15 images at different distances and combined them to make the final image. We’re curious how the pringles can macro lens would compare to this. Thanks for the submission [sp’ange]. Lets see some more tips.
Since we rely on you, our loyal readers, to supply the tasty projects that we thrive upon, we felt this writeup about how to photograph LEDs could be very useful. Photographing them can be quite difficult at times, they throw off the standard settings on your camera pretty easily. EMSL takes us through all the settings for best results. While you’re brushing up on your photography skills, you might want to consider making a flash ring, or some kind of macro lens. Now go take some awesome pictures and submit your projects.
