Slave Flash Trigger for Digital Cameras
The synchronizer ensures a contact-free, optical synchronization of external photographic flashguns. The triggering of the external flash is derived from embedded flashes of a camera. It can be used for both digital and "analogous" cameras or for a remote synchronization of the actual flash units. Its use is optimal especially with digital cameras (DC), where extraordinary adaptability for different systems will stand out. It is capable of eliminating the effect of any measuring pre-flashes. The synchronizer thus perfectly fulfils the role of a device often called the Slave Flash Trigger (SFT) __ Designed by © Pavel Janko
Slave flash trigger with counting logic
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. __ Designed by Jim Rowe
Solar Powered Infrared 1W Security Camera Illuminator
Many security cameras are equipped with an array of infrared LEDs to illuminate an area in front of the camera with invisible light for night time surveillance. However, there are times when a remote area, well away from the camera, needs additional infrared light. The circuit below uses a modified solar powered path light to bathe a fairly large area with 850nm infrared light. . . Circuit by David Johnson P.E.-June, 2014

Time-lapse photography with a QuickCam
Something I've wanted to do for quite some time is a time lapse movie of a static view, spanning an entire year. It could be presented in a number of ways, for example a fast 12-second (30fps) view of one exposure at noon every day, or a longer sequence covering all the daylight hours, equalized for brightness, or an even longer one covering all hours. Also I would want to make a 2-dimensional graphic, 365x240 pixels, one for every 10 minutes of the year, with the pixel colour being the average colour of a small patch of sky. __ Designed by Markus Wandel

Timer for Darkroom Camera Shutter
This circuit was designed to control a film exposure shutter for a darkroom. It has 8 time steps ranging from 0.35 seconds to 4 seconds. It is activated by a foot switch and draws power from an external 12-volt DC supply . . . Hobby Circuit designed by David A. Johnson P.E.-June, 2000
Universal Exposure Timer & Event Counter
This page is the result of a lot of effort over the past couple years to develop a quality, inexpensive device to test shutters on the classic film cameras that I have been using. The latest design I have developed uses a micro-controller to time and capture the events and upload to a computer with a serial interface. It turns out that with a simple plug in sensor, I have come up with several potential alternate uses for the exact same design __ Designed by Mike last name not found

Wireless Camera
In general, avoid wireless cameras that transmit video, especially on 2.4 GHz. They tend to interfere with wireless routers. On the other hand, there are excellent wireless cameras that will work with your wireless router.
