A Simple Circuit home-made light-operated camera trigger
This device is used to photograph moving objects by triggering a camera or flashgun when one or two light beams are interrupted. It was designed to capture insects in flight, but can also be used for projectiles and anything else that moves too fast or irregularly to be photographed by hand. It cost around $30 to build, and was used to make The Barista Collection. __ Designed by Mark Harris Photography
A 'Smart' Slave Flash Trigger
Does your camera's flash operate in red-eye reduction (multiple flash) mode only? This clever unit counts the number of "pre-flashes" before triggering a slave flash unit.___ SiliconChip
AI-1 ("All-In-one") Remote-photographic accessory that you can build
One of my other hobbies is photography, and, about a year ago, I purchased a new digicama Panasonic FZ30. I joined the Panasonic forum on the dpreview site. One of the posters, a programmer and electronic hobbyist, designed a nifty wireless remote using a very inexpensive RF transmitter/receiver combination that he found on eBay. After he'd perfected that, he began designing an interval timer using a Radio Shack egg timer. __ Designed by © 2007 Tom Lackamp
Arduino based Motion triggered camera using a PIR sensor
Arduino has taken off as an incredibly popular building block among ubicomp (ubiquitous computing) enthusiasts, robotics hobbyists, and DIY home automation developers. __ Designed by "Kubrick" Michael Heilemann
Automatic Camera Shutter Releases
I've used two methods to electrically sense a rocket launch to trigger a camera. The first thing I tried was a normally-closed circuit created by clipping an alligator clip totop ofmetal launch rod.

But, it had __ Designed by John DuBois
Automatic-exposure scheme uses CCD shutter
EDN-Design Ideas July 2, 1998 [ NOTE
: File has multiple design, scroll for this one.] This application follows the Design Idea, "Peak detector maximizes CCD-sensor range" (EDN, Aug 15, 1996). Its aim was to optimize the performance of an A/D converter used to digitize a linear CCD sensor's analog output. The method involved stretching the upper reference of the flash ADC for the highest lit pixel in the array. The method works well, but does not obtain the best performance from the CCD, which can saturate for overexposure or can produce noise for underexposure. Figure 1 shows a better method that you can use with CCD sensors that provide a shutter facility. The shutter signal in a modern CCD array (such as the Sony ILX703A) removes the electrical charges the light produces during the exposure.__ Circuit Design by Giovanni Romeo and Sandro Rao, Istituto Nazionale Di Geofisica, Rome, Italy

Batteries charger & PSU-Ideal for digital cameras
This circuit was created for digital cameras. It's known the digital cameras have considerable power consumption. For example my camera Minolta E223 requires. __ Contact: IQ Technologies
Build a Raspberry Pi-Based Cable Shutter Release for Sony Cameras
Replacing a simple and inexpensive remote cable release for your camera with Raspberry Pi may seem like a classic case of over-engineering, but using the tiny machine to control the camera opens up a whole new world of photographic opportunities. Using a simple Python script, you can turn Raspberry Pi into a powerful and flexible intervalometer or trigger the shutter using sensors connected to the computer. Add to Raspberry Pi a Python-based web app, and you can control your camera from any computer or mobile device. __ Designed by Dmitri Popov
Build a Simple Circuit one-chip phototimer
8-Jul-04 EDN-Design Ideas Recently, I needed to automatically switch on a lamp when it became dark and keep it on for a given time. Trying not to reinvent the wheel, I looked through what was available on the market, but I could not find an inexpensive device that satisfied the requirement. Some products worked like a photoswitch, lighting a lamp when it becomes dark and keeping it on while it is dark—in other wor__ Circuit Design by Abel Raynus, Armatron International, Malden, MA
Building a Digital Intervalometer-Includes & suggested layout
Having used a single frame advance Super-8 and a couple of Sony Hi-8 video cameras to do some time lapse work over the years, Minolta's implementation of an intervalometer has left a lot to be desired in the Dimage cameras. __ Contact: John A. McCulloch |
