This entry for the 555 timer contest is from Andrew Smith who built a motion activated switch for a digital camera. The 555 timer is operating in monostable mode which is triggered by a PIR sensor when motion is detected. The monostable output of 555 then activates the camera through a remote.

I needed a foot switch for my DSLR camera so that I could take hands-free pictures. On a long-shot, I went down to the local Radioshack to see if they had one. As expected, they didn’t have any camera foot switches, but I did luck out that they had all the parts necessary to build my own. Here is how to throw together a 5-minute camera foot switch with easily obtainable parts from Radioshack.

I decided to make a quality DIY intervalometer for my DSLR Pentax camera. This intervalometer should work with most major brands of DSLR cameras such as Nikons and Canons. It works by triggering the shutter using the camera’s remote trigger port. It can also auto-focus before each shot if so desired (or toggle this on or off at any time). The brains of this intervalometer is an Arduino chip. It may seem very complicated at first glance, but is actually a simple circuit and not that hard to make.

Not many people know, that regular camera can be used as night vision device because it’s able to take pictures in infra-red spectrum. If scenery will be lighted by source of those rays, for human eyes it will be dark, but camera will be able to take pictures. Learn how to take pictures in IR spectrum in the link below.

This project will show you how to make an intervalometer that can be used with virtually any camera. It has been tested with Canon and Nikon cameras, but making adapter cables for other cameras is just a matter of figuring out the camera pinout.
This intervalometer has the following features:
- Intervalometer mode with options to change delay time and exposure time
- Sensor mode with built in light sensor and connector for external sensor input
- Manual mode allows intervalometer to act like a simple remote cable
- Integrated 2×12 LCD display
- Fully optically isolated interface to camera
- Total package is roughly 1″ x 2.5″ x 3″ finished
- Electronics small enough to fit in a mint box
- Source code is available for download so that you can change programming as desired
- Available as a kit from www.ottercreekdesign.com

This instructable shows you how to add a time lapse module to a Rollei Compactline 52 digital camera. The idea could also be implemented for other point and shoot cameras. The device is able to power on the camera, take a photo and then shut the camera down. In this way the battery will last plenty of time. It is based on ATtiny24 and length of time between shots can be configured. It also has the feature to automatically shut down when it gets too dark outside. Check schematic and board files on the link below. [via]

This instructable shows how to build cheap motion detection wildlife camera. This project uses a re-purposed PIR sensor module from an air freshener to provide motion detection, an inexpensive key chain camera to capture images, and a TI msp430 microprocessor to provide the necessary control. Check it out on the link below.
