[Peter Johansson] has taken it upon himself to build a medium format camera, from scratch. We know this is a shock to some of you, but this camera uses traditional medium. There is no sensor. He will be loading it with (gasps) film. He bought the lenses pre made, but everything else is being constructed by himself. Probably the most notable parts are the aperture and the shutter. The project is about 80% complete right now. We can’t wait to see it finished.

We’ve covered almost every way possible to remotely control a camera setup, from lasers, to Lego, to doorbells, and even having a Nintendo DS run the show. But at the end of the day, what if you want something that’s small, simple, has amazing flexibility for future additions, and most importantly doesn’t take away your favorite game system. [Whiternoise] wrote up an extremely detailed guide on getting an AVR to control your camera. We like the clean look the final product has, and the large amount of possible add-ons is a major plus. What do you look for in a cheap multi-function wireless camera controller?
We keep waiting for evolution to give us that third arm but in the mean time, this may be the solution for holding the camera while you document your projects. [DHagen] has made a four legged tripod (quadpod) for his camera in order to use it as a digital copy machine. We’ve spent many a night trying to get a steady and sharp video of an LCD or array of LEDs in action to document our weekend tinkering and this will make that all a lot easier.
His build uses materials that will total between $10-$20 at the hardware store down the street. A chunk of scrap wood is connected to the camera using a bolt in the threaded tripod hole of the camera. Two L-brackets are attached to the wood so that one is on either side of the camera lens. This leaves two mounting holes on either side of the lens to attach threaded rod using nuts. The assembly is capped off with a square of acrylic (plexiglas).
Quick and clean. It’s not the cheapest camera mounting solution we’ve seen, but it sure does a good job.
[Nick Nichols] set out to take a photograph of a full redwood tree. Here’s the catch, these redwoods are over 300 feet tall and they’re not just standing in the middle of a vast desert. If the photo is taken from a distance, you will only capture the top part of these majestic beauties. How can you take the shot from close up? Build a custom rig to take multiple shots and stitch them together for a composite photo.
[Nichols] built the rig to hold three cameras focused to the left, middle, and right of the tree. The frame includes a gyroscope to keep the cameras steady. By lowering the cameras from the top to the bottom of the redwood they were able to capture 84 pictures to assemble the final shot. The result is featured in the October edition of National Geographic magazine. We’ve included the final picture and embedded a video of the rig in action after the break.

Popped balloons or bullets fired into apples, anyone can photograph with a quick sound based camera rig. Lasers have been used forever in motion detection. And even door bell chimes have been used before for remote camera shutter releases. No, [SaskView] wanted to go further and created his Laser Triggered High-Speed Photography setup, to photograph (of all things) milk splashes. We liked the simplicity of the project however; requiring no programmed microchips or overly complicated circuitry – rather he took a quick trip to the local dollar shop, used the amazing CHDK firmware, and he produced perfect results every time.
[Update: CHDK, not CHKD firmware. My mind must be elsewhere. Thanks jbot and agent smith]
As part of a “disruptive technologies” course at the United States Military Academy, [Roy D. Ragsdale] produced a working prototype of a Google Street View-like system called PhotoTrail. Like its corporate-backed inspiration, the system captures georeferenced 360-degree panoramas that can be viewed interactively in a web browser…but at a hardware cost of only around $300. [Ragsdale’s] prototype is based entirely on consumer-grade off-the-shelf components and open source software, all tied together by the yin and yang of DIY: foam core board and a few Python scripts.
This article from IEEE Spectrum magazine provides some background on the selection of parts and construction of the system, including a hardware shopping list and a list of links to all of the open source packages used.
The PhotoTrail prototype is surprisingly small and lightweight. A vehicle isn’t even required; the camera array can be carried overhead by a single person, making it possible to capture remote locations. But [Roy] expects future revisions to be even smaller and less obtrusive, perhaps mounted to a headband. Mount Everest awaits!
Back in 2005, a member of a French robotics team named [Laurent] wrote a wonderful how-to that we somehow missed on using the Game Boy Camera as a vision device for a robot. The images above are actual shots from his project. The Game Boy Camera features a stunning 128×123 pixel resolution in a gorgeous 4 color gray-scale palette. Possibly the most attractive feature of this hack is that it is still possible to get a hold of these cameras for under ten dollars on ebay.
He connected the camera sensor to an Atmel AT90S4433 using a combination of digital and analog signals, and then used the microcontroller to echo the data back to his PC. His write up includes schematics for wiring up the sensor/microcontroller, the datasheet for the sensor, his C code for the whole project, and an easy to read pin out of the GBC connector. Although his project simply offloaded the image to a computer, it would be entirely possible to have the microcontroller respond to the image or simply just log and store it. It would also be just as easy to replace his Atmel chip with your own favorite microcontroller, as long as it has a couple Digital I/O ports and at least one Analog port (or an external analog to digital converter).
UPDATE: Good catch r4v5, it would require an ADC, not a DAC.
