How to Make a 360° Analog Camera Hat

Mike Warren has written up an in-depth tutorial on how you can build a 360° camera hat using 6-8 disposable cameras. The cameras are worn around the head like a crown, and are simultaneously trigger using a single shutter release with the help of servo motors that depress the shutter when triggered. Warren writes,

With the camera array sitting on your head, you're able to capture a 360° panorama view of your surroundings. This project requires no special electronics knowledge and can be assembled in about an hour.

I designed this camera array off something I saw on the "Radar Detector" music video by Darwin Deez. But, after making the camera hat, everyone kept asking if it was a low-fi version of Google Street View. It's more the former than the latter, but people can draw their own interpretations.

Use a Nail and Clothespin to Determine Placement When Hanging Photos

Michele over at The Scrap Shoppe offers this handy trick for hanging picture frames: hammer a nail through a clothespin and use it to determine nail placement. Simply hang the picture on the clothespin nail, figure out where you want to place the frame, and then push the clothespin into the wall to make a small indent. Voila! Target acquired.

Use a Red Dot Sight for Locating Subjects with Super Telephoto Lenses

Photo enthusiast Chris Malcolm needed a better way to aim his 500mm lens at fast moving subjects (e.g. birds in flight), so he upgraded his lens with a DIY sighting aid by attaching a non-magnified red dot sight:

They're designed to clamp onto a gun sight wedge mount, so some kind of adapter is required. I played with the hot shoe mount, but it was too flexible -- the sight needed re-zeroing at every mount, and was easily knocked out of calibration. The degree of precision required to aim the central focus sensor at the target via the dot also made parallax error a problem on the hot shoe. So I decided to mount it directly on the lens. Least parallax error, plus the geometry of the lens barrel and the sight mount naturally lines it up with the lens. To protect the lens barrel I glued the sight clamp to a cardboard tube slightly too small, slit open to provide a sprung grab on the lens body. The slit also handily accommodates the focus hold button on the lens barrel.

Malcolm reports that the site "works amazingly well", making it "trivially easy to aim the lens at anything very quickly".

Siri Ported to the Canon 5D Mark II?

A Swedish hacker and robotics student named Björn Mabrö is claiming that he has successfully developed a custom firmware for the Canon 5D Mark II that adds Apple's Siri voice assistant to the DSLR. Mabrö claims that the hack allows the camera to respond to 124 different voice commands that control everything from the shutter to changing values in settings.

How to Make Your Gloves Compatible with Touchscreen Cameras

We've featured special gloves and mittens designed for photographers before, but what if your camera uses a touchscreen instead of physical controls? Here's a video by Make's Becky Stern showing how you can sew some conductive thread into your glove to make it compatible with capacitive touchscreens.

Play Around with Macro Photography Using a Magnifying Glass

You don't need to shell out money for a nicer camera or a special lens to play around with macro photography. In addition to freelensing and using your lens backward, you can also place an ordinary magnifying glass in front of your lens to enlarge the world. Graphic designer Clif Dickens shot these close-up photos using a magnifying glass and an iPhone 3GS.

How to Unlock the Hidden Panorama Mode in iOS 5 Without Jailbreaking

A couple days ago it was discovered that iPhones, iPods, and iPads running iOS 5 have a secret panorama mode that's hidden in the operating system. The feature can be enabled, but featured either a jailbroken device or knowledge in how to edit a particular iOS 5 preference file. Luckily for non-hackers, Redmond Pie has discovered an easy way to do this by taking advantage of iTune's backup feature. This tutorial will teach you how to get the panorama feature unlocked in 5-10 minutes.
