Fresh hacks every day
[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 … [Read more...]
[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. … [Read more...]
[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 … [Read more...]
Both Canon and Nikon recently released DSLR cameras that now include a feature that most consumer level digital cameras have had for sometime: the ability to record movies. What makes movie recording especially appealing on a DSLR is the wide selection of lenses available to get the look you're after. If you're an owner of Canon's 40D you may want to follow [DataGhost]'s progress on the CHDK forum … [Read more...]
We've seen numerous products geared toward tracking the location and activities of your pets, two in the last month, but we feel sure you can make more functional devices than those you can purchase. Let's look at a few and consider our options. … [Read more...]
So you got CHDK working on your camera, and the histograms, raw image files, variable shutter speeds and other added functions are amazing, but stereo imaging is what you really want. If you have two or more CHDK-ready cameras, it's cheap and easy to run StereoData Maker, a system that synchronizes the shutter and flash of multiple cameras. The first step in getting SDM to work is installing the … [Read more...]
Today is the Fourth of July in the US, where we celebrate our freedom by blowing up a small portion of our country. Embedded above is [Jory] and [Jonathan] doing it wrong by microwaving their fireworks. We think a good formula for this year's celebration is wireless fireworks control, gas powered blenders, and CHDK's motion sensing to get the perfect firework photo... and if we get really bored … [Read more...]
