Lego Pinhole Camera

December 30, 2010 by Mike Szczys 8 Comments

[Bshikin] built a pinhole camera out of Lego pieces (translated). It is a fully automated unit thanks to the integration of the NXT pieces. It took a bit of careful calculation to get the film spacing adjusted to match the focal length, and quite a bit of tape was necessary to keep light out of the film chamber. But in the end, it’s an amazing build that takes decent pictures. The software has settings for film size and speed, and takes care of exposing and advancing the frame at the click of a button. See for yourself after the break.

Upgrading An Old Polaroid Land Camera For 35mm Rolls

December 26, 2010 by Caleb Kraft 19 Comments

Ok, we recognize that this is a bit of an odd upgrade, since many would probably think that a digital upgrade would be more appropriate. However, we found this interesting anyway. [Marker1024] has taken this old Polaroid land camera and modified it to accept a standard 35mm roll. His list of materials may sound fairly MacGyver-ish with foil and sculpey, but his results look to be well done and fairly sturdy. We have to say that the aesthetics of the camera itself are quite appealing and we could see carrying one of these around. As interesting as the writeup is though, we can’t help but wonder what the pictures look like that came out of it!

BendDesk Multi-touch Furniture

December 3, 2010 by Mike Szczys 23 Comments

The BendDesk is a horizontal and a vertical multi-touch display connected as one curved surface. Think of it as a smart white-board and a multi-touch desk all in one. It can be used to sort and edit information, or to play games. Check out “Bend Invaders”, a game demonstrated in the video after the break. When you touch two fingers to the display the two points are used to aim a laser at the oncoming monsters.

The system uses a combination of two projectors shining on the surface from underneath and behind. A series of LEDs around the edges of the display bathe it in infrared light. Three cameras with IR filters peer at the underside of the acrylic surface and detect touches by distinguishing variances in the IR pattern through a process called Frustrated Total Internal Reflection. If you’re interested in more of the math and science involved there are a couple of papers available from the project site linked at the top of this post.

We’ve seen so many displays using the Kinect lately, it’s refreshing to see one that doesn’t.

Timelapse Circuit For Point And Shoot Cameras

November 23, 2010 by Caleb Kraft 15 Comments

[Andyk75] has done some fantastic work documenting his timelapse addition to his digital camera. Most of the more expensive models of cameras have a remote shutter release, but the point and shoot jobs usually don’t. He decided to add the ability to turn the camera on, then shoot a picture, then turn it back off. Pretty smart, since these things tend to eat batteries pretty quickly if left on. He is using an ATtiny24 for the brains, but the circuit should be pretty adaptable to others. The final piece has several features, like the ability to change the length of time between shots and automatically shut down when it gets too dark outside to continue. He has posted the schematics as well as the board layouts if you can find them amongst the ads in instructibles. You can check out a video of a sunset taken with this camera after the break.

Motion Activated Wildlife Camera (or A Spy Device)

November 21, 2010 by Mike Szczys 20 Comments

Now you can capture pictures of our furry friends by building a motion activated wildlife camera. [Doug Paradis] took his Air Freshener hack and used it to trigger a camera. The white dome in the picture above is the PIR sensor from an Air Wick Freshmatic, along with a cheap keychain camera and an MSP430 microcontroller. He used one of the chips that came with the TI Launchpad, a transistor, and some discreet components to interface the devices and then put them into a project box. Now he’s got a fully configurable motion-sensing camera.

Retro Adapter For Canon SLR

November 20, 2010 by Chris Nelson 19 Comments

[calculon] was able to modify a “dumb” adapter to allow his Canon SLR to use the aperture and focus on a retro lens. With his new flip mounted wide angle lens he was able to achieve some pretty neat macro shots. By cutting away some of the cheaper ring he was able to feed the wire through and glue it onto the the cameras contact points. The wire was then attached to the inputs on the “new” lens. With a new adapter running about $375 not only was this a neat little hack but it was also a money saver. You can see some more of his photos on his flicker

Portal…shirt?

October 26, 2010 by Jakob Griffith 29 Comments

[Ben Heck] is in the Halloween spirit with his Portal inspired “see through” t-shirt. That is, a thin lcd is mounted on [Ben’s] chest, with a not as thin camera mounted on his back; when the system is running, everything behind him is captured by the camera and displayed on the LCD. The concept isn’t exactly new by any means, often by the name of “gaping holes” or “hole through body” or more, but the project goes to show that a creative costume isn’t always the most elaborate, expensive, or even a new idea. Catch a video of how to make your own Portal shirt, after the jump. Oh, and you can win the Portal shirt here.
