Rear View Jacket

June 21, 2008 by 10 Comments


Is your popped collar so epic it emulates horse blinders? Are punk teens always skitching your coattails? Are you constantly moonwalking into power poles, trash cans, and the elderly? [Paul Coudamy]’s Hard-Wear Jacket solves all of these problems. It has a micro-camera embedded in the back of the neck and streams live video to a sleeve mounted monitor. The goal is to expand the perception of the wearer and how they interact with the environment. We know this is just a small step and doubt many people will be scrambling to never turn their neck again. It’s something interesting to contemplate though: how will people behave when brain taps allow their peripheral vision to have the same clarity as normal vision?

Waterproof USB For Underwater Cameras

June 20, 2008 by 10 Comments


Underwater camera housings work great – but they are prone to humidity, dirt and dust problems if you open them more often than needed. In order to download the images off of his digital camera between dives, [Matt] decided to add a waterproof external USB port to his housing. He had an extra 5 pin strobe bulkhead installed by Ikelite (makers of excellent housings). Then he spliced on a mini-usb cable for the camera and spliced a standard USB end onto a strobe cable. During dives, the port is closed with an o-ring sealed cap.

TI-83 Intervalometer

June 9, 2008 by 12 Comments


The headline How to Make Time Lapse Video With Your DSLR didn’t really grab us. Honestly, you pay that much for a camera and it can’t do time lapse out of the box? Well, we nearly missed the real story: [Chris Martino] was using a TI-83 to act as the intervalometer for the camera. The calculator has a 2.5mm audio jack for it’s data port and the camera has an identical port for the shutter trigger. The TI-83 runs a program with a FOR loop to act as the timer. When the loop completes it sends data to the port, and the voltage triggers the shutter. The rate isn’t very exact and varies depending on the charge left in the batteries. [Chris] estimated 10000 program iterations ends up being about 26 seconds between pictures. This technique has been tested on 84, 86, and 89 series calculators too. There are a couple example time lapse videos embedded after the break.

Porting CHDK To New Cameras

May 27, 2008 by 9 Comments


While researching the CHDK How-To, we came across the team’s instructions for porting the firmware to entirely new cameras. In theory, CHDK should work on any Canon running the DIGIC II or III processor since most of them are running the same VxWorks OS. A dump of the camera’s firmware is required before porting work can begin. On some cameras, the firmware was retrieved using software, but others required a hardware route. Pictured above is a Canon A610 that’s slowly flashing out every bit of its firmware using the built in LED. The photodiode is hooked up to a soundcard where the entire bitstream is recorded. It takes 1-7 hours to read the entire firmware. Once the sound file has been captured, it’s reverted to the original bytes and can then be decompiled with something like IDApro.

How-To: Expand Your Camera With CHDK

May 27, 2008 by 50 Comments

As anyone who has lusted over the technical specifications for Canon’s new Digital Rebel XSi knows, the capabilities of the average point and shoot camera are severely limited. Using the CHDK firmware hack, the features of Canon point and shoot cameras can be significantly expanded, allowing for ultra-high speed photography, very long exposures, time lapse photography, and RAW capture. This How-To provides a guide to our experiences using the CHDK firmware, and shows just how easy it is to get more out of a point and shoot than ever thought possible.

Underwater Camera Housings

May 24, 2008 by 7 Comments

Underwater cameras can produce some amazing photography, but who wants to pay for housing if you can make something yourself?

This underwater camera housing on Instructables doesn’t require a specific container, allowing you to choose anything you have around the house that’s watertight and large enough to fit your camera. A finger from a glove is added so you can still operated the controls. A similar project uses an insulated water jug, accommodating any camera that fits inside. Neither of these involve any camera mods.

Notacon 2008: The TSA Bagcam

April 6, 2008 by 15 Comments


[algormor] gave one of the more controversial talks at Notacon. After receiving a few too many inspection slips and destroyed baggage he decided to find out what was going on behind the scenes. First, he purchased a cheap bag from Walmart with a zipable liner. To record the video, he purchased a SwannGUARD MicroDVR. It’s a palm-sized device that records 128×128 15fps video. It comes with a plastic cover that he mounted to the inside of the bag. A hole was cut for the video camera right above the badge holder. Since the camera is motion triggered, he could slide the badge up, covering the hole, to deactivate the camera. He’s taken the bag on at least four trips. So… what did the footage show?
