[Lozzless] has a steady hand and plenty of confidence in his hacking skills. The video above is worth watching for the full eight minutes. In it you’ll see him convert a lens into what he calls a SuperMacro lens with a working aperture. The process involves fashioning a connector ring from a lens cap, modifying an Electro-focus lens mount, and assembling the parts to do his bidding. We don’t have the photography background to fully understand what he’s doing here, but we can appreciate the process, and the results are shown at the end of the clip.

Classic Canon AE-1 Gets A Digital Upgrade

May 5, 2010 by Mike Szczys 33 Comments

Shots of this Canon AE-1 camera-gone-digital have a lot of people scratching their heads. Originally there were a lot of “that’s been photoshopped” cries but the video after the break shows that it physically exists. This particular model of camera hasn’t been manufactured since 1984 so there’s little chance that the company’s bringing it back in a digital format. What we have here is a classic camera body with a modern point-and-shoot fit inside. This seems to be a PowerShot SD 870 IS and we’d guess the original lens has been replaced with a plate of glass so as not to affect the PowerShot’s focus, and the “AE-1 Program Digital” screen is probably just an image on the memory card.

We admire the clean mod work necessary to produce this hack.

Perfect Spiral, Every Time

April 30, 2010 by Jakob Griffith 20 Comments

[Carmine] let us know about his team’s Automated Football Launcher. Their goal was to combine a football launcher with motion tracking, to allow a player to practice running and catching with the perfect throw. Unfortunately, and we’re not quite sure when, they ended up changing out the Jugs machine for an air cannon, which resulted in the use of foam footballs and the loss of throwing factors such as spiral. Somewhat defeating the purpose but we’ll let it slide; only because we know its going to be shooting potatoes eventually.

The project comes together by using two cameras giving distance and color tracking, combined with a rotating platform (and the best use of garden hose ever), an accurate set-top for their launcher. As seen in the video after the jump, it works out quite nicely. Continue reading “Perfect Spiral, Every Time” →

Third-person Vehicle

April 6, 2010 by Jakob Griffith 27 Comments

Here is something we didn’t expect (NSFW). The machinima crew behind RedVsBlue, Rooster Teeth, actually did a hack!

The idea is simple enough, how could you experience driving a vehicle like in a video game – aka, third-person. With some steel bar, Canon 5D camera, and a 15inch monitor inside of a blacked out cab, they accomplished just that.

What surprised us the most, is the great difficulty and difference there is between the video game vehicle and the real life one. But all of us here at HAD know why; they need to replace the steering wheel with a joystick. While they’re at it they can make it wireless and remote-controlled. Finally a HUD would be easy enough to program (might we suggest processing). Oh dear lord, is the world ready for this!?

Precision Erector Set Connects Multiple Cameras

Check out the exoskeleton that [Curt von Badinski] built for filming driving scenes. This extremely configurable wrap-around frame resembles a children’s toy from the past but allows an almost unlimited set of configurations. Five cameras simultaneous capture the driving scene. The current setup is used to shoot the television show 24.

Pictures From Space For $150

prelaunch

Ever wanted to be able to launch a balloon into space, track its location via GPS, take some photographs of the curvature of the earth, and recover the balloon, all for the low low cost of $150? [Oliver Yeh] sent in his teams project, Icarus, which does just that. The group of MIT students found that they could use a weather balloon filled with helium to reach heights of around 20 miles above the earth; their particular balloon achieved 93,000 feet (17.5 miles). Then, utilizing only off the shelf components with no soldering, conjured up a GPS tracker using a Motorola i290 Prepaid Cellphone. They then used a Canon A470 loaded with the chdk open source firmware to take pictures. After seeing the results of their launch, the team hopes that this could rejuvenate interests in science and the arts.

Camera Peltier Cooler

July 23, 2009 by Zach Banks 36 Comments

[Gary Honis] has been modifying his Canon Digital Rebel XSi in order to do astrophotography. He previously removed the IR filter and replaced it with a Baader UV-IR cut filter that lets most infrared light through. However, in order to reduce noise in the pictures, he had to cool the camera down. He based the project on a peltier cooler that he salvaged from a powered beverage cooler. He made a small aluminum box and insulated it with styrofoam to hold the camera body. The peltier cooler was then attached on the side. It takes just over an hour to cool the camera down to 40 degrees, but the shots come out a lot clearer.
