Camera Shutter Timer
This was a quick hack to measure camera shutter speeds, motivated by my finding out that my first SLR (an Olympus OM-10 purchased secondhand a few months earlier) had a shutter problem. After I had the camera repaired, I used this to check that the shutter speeds were OK, and later used it to test various mechanical shutters on other cameras. __ Designed by Markus Wandel
Camera Subs as a Scope Camera

Camera Trigger
In 1984 I made a camera trigger to capture transient phenomena. I had a Mamiya ZE 35mm camera and Mamiyalite ZE flash unit. Typical for bodies of its time, the only means of remotely triggering the camera was the cable release socket built into its shutter release button. This was meant to be used with a purely mechanical cable; it let you operate the shutter release from a small distance away, and in a manner that avoided introducing vibration to the camera at the moment a picture was taken __ Designed by John DuBois
CamTrig-A 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
Canon DSLR cable shutter release usin 4N25 for optical isolation
The most essential accessory for astrophotography, after a camera, scope and mount, is a remote shutter release to reduce vibration. A remote control is even more useful if it can trigger a series of exposures at preset intervals and of preset duration. __ Designed by Jim Easterbrook

Cellular-telephone/camera-flash illumination
05/27/04 EDN-Design Ideas Successfully implementing flash lamps involves understanding numerous practical considerations. Next-generation cellular telephones will include high-quality photographic capabilities. To support their improved image sensors and optics, they will need high-quality "flash" illumination, which requires special design attention. This lighting is crucial for yielding good photographic performance and requires careful consideration.__ Circuit Design by Jim Williams, EDN's most revered contributor, passed away in June 2011 after a stroke. He was 63.
Chase the Stars with a Camera
11-Mar-10 -Design News: Who hasn't looked at the night sky and asked in awe, "How can I capture that?" A motor-driven star tracker won't let you grab a star, but it will let a camera track the movement of the stars so you can take spectacular photos. The trick involves setting the proper tracking rate and pointing the __ Gadget Freak-Case #160
Cheap Close-Up Camera Lens
I often use my digital camera to take photos of some electronic projects. At times, I need to get in close to capture some details. But, without some additional optics, my camera just could not maintain focus, as I received closer to an object. Being a cheap . . . Hobby Circuit designed by Dave Johnson P.E.-April, 2005

Collection of high-speed flash photographys
Electronic flash can be used to take sharp photographs of events occurring at high speed. Most flash units designed for amateur photographers can provide flashes of light as short as 30 millionths of a second. This is sufficient to "stop" such events as the impact of a tennis ball with a racket, a foot with a football, and the burst of a balloon or a popcorn kernel.___ Loren M. Winters
Complete Power Solution for Portable Cameras
The LT3587 and LT3586 can combine to provide all required supplies for a digital camera: 3.3 V AT 1A for system I/O, 1.8V AT 400mA for memory, 1.6V AT 400mA for core supply, 5V AT 800mA for audio/motor drive, positive (15V AT 50mA) and negative (-8V AT 100mA) CCD imager bias and white LED backlighting __ Linear Technology/Analog Devices App Note, Mar 24th 2010
Computer Sound Port Shutter Tester
I have implemented a sound port shutter tester, which is described later on this page. However I am disappointed with it's inconsistent performance at higher shutter speeds and the inability to make the HW work on different computers. In order to rectify the situation I've designed a shutter tester that interfaces directly to an old Apple ][ computer, and am much happier with that solution. __ Designed by Mike last name not found
Computerized Shutter Control of Canon DSLRs
Joe Zeglinski has developed a variant of the control cable design for Nikon DSLR Cameras. This simple modification enables existing shutter control software to support Nikon DSLRs in addition to Canon ones. As a bonus the modification also allows the use of the Canon hand-held TC-80N3 timer controller with Nikon cameras. __ Designed by Paul Beskin
