Large collection of strobe / photoflashs Notes on the Troubleshooting and Repair of Electronic Flash Units and Strobe Lights __ Designed by Samuel M. Goldwasser

Lightning Activated Camera Shutter Trigger This circuit is used to trigger a camera's electronic shutter circuit when a flash of lightning is present.  This circuit would also work for photographing fireworks displays or other events involving flashes of light. __ Designed by G. Forrest Cook

Lightning shutter trigger for a camera using an Arduino I knew there were devices that could trigger a camera to fire during a lightning strike, but their circuits were more complicated than I wanted to make.  Iím a software guy not a hardware guy so I decided to use an Arduino and that allowed me to write a little code that made the circuit much simpler. __ Designed by Ravi Upadhyaya

Making your own RS-60E3 Remote Control for Canon EOS cameras Welcome to, ashamedly, the most popular page on my website.  I'm not really sure why, but I guess people like these do-it-yourself projects.  Promise me you'll go look at pretty pictures after this, okay? __ Designed by Markus Wandel

Mercury battery replacement Many old cameras and other devices used mercury batteries, which are no longer available.  Here is an analysis of the problem, and a few solutions. __ Designed by Manfred Mornhinweg

Nikon Coolpix 950 / 990 / 995 Flash-adapter The Coolpix 9xx series are some of the best digital cameras on the market especially the 990.
However the internal flash is too close to the lens which results in red eyes in all portrait shots.  The internal flash also drains the camera batteries and extends the time until the camera is ready after each shot.  Therefore an external flash is one of the ost useful accessories. __

Nikon IR-Remote Control based on Atmel ATtiny13 A few months ago one of my visitors gave me an idea for a new small project, an IR remote control for my Nikon DSLR camera.  Not that I absolutely need one, surely I don't need it bad enough to get one for about Ä30 or Ä40 from e-bay.  However it would make a nice little in-between project. __

 

Not-So-Basic Timer A more advanced timer with added input and output circuits.  Shown used with Fuji 60 AF. __ Contact: archilochus57 @ yahoo.com

One Transistor Timer A very simple long duration timer with minimal components.  __ Contact: archilochus57 @ yahoo.com

Open Source Optical Flash Trigger that Works with Any Camera Normally, you canít use a camera without a hot shoe with an external flash unit.  But a relatively simple Photon-based device can solve this problem.  Many external flash units (including older ones) can be triggered by shorting (i.e., closing the circuit) between its two terminals.  If you happen to have a flash with a PC Sync terminal, it most likely can be triggered by shorting the connectorís pins. __ Designed by Dmitri Popov

Optical Slave Flash Trigger 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

Photo Flash Charger Minimizes Parts Count 10/22/98 EDN-Design Ideas  Photo-flash and strobe devices operate by discharging a high-voltage capacitor into a bulb.  Charging the capacitor from a battery or other low-voltage source requires a step-up DC/DC converter to boost the voltage, typically to 300V.  One way to generate the high voltage__ Circuit Design by Steven Chenetz, Micrel Semiconductor, San Jose, CA

Phototimer Controls Load 04/18/02 EDN-Design Ideas In industrial and home applications, the need sometimes exists for a device that, after activation by some physical effect, such as light, temperature, or sound, switches a load on for a predetermined time.  The load, such as a lamp, motor, solenoid, or heater, usually derives its power from the ac line__ Circuit Design by Abel Raynus, Armatron International, Melrose, MA

PIR Camera A simple automatic motion-detection Digital Camera. __ Contact: Collin Mitchell

Programmable Optical Slave Flash Trigger for Digital Cameras using PIC12F675 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

R/C Digital Camera Controller My personal experience with R/C airborne video is focused on wireless video systems that transmit realtime images.  However, airborne still photography is quickly becoming a popular alternative, especially since it avoids all the FCC/ham license issues.  And the new mega-pixel digital cameras are low cost and are surprisingly small.  Nearly any model aircraft can haul one around. __ Designed by RC-CAM T. Black

R/C Helicopter Camera Although the RC-CAM2 system is no longer used, you will certainly learn a lot by reading the details to building it.  Like many good things, its useful life has come to an end and it has been replaced by the latest project called RC-CAM3.  But for historical benefit, the original RC-CAM2 project is listed below.  Enjoy! __ Designed by RC-CAM T. Black

Radio Remote for PIR Sensor Works with "basic sensor" above and can be modified to work with many other sensors.  In progress! __ Contact: archilochus57 @ yahoo.com

RC Controlled Digital Camera The aim of this project was to get a digital camera into a small electric radio controlled (RC) airplane and still have it fly.  The airplane shown, a park flyer, weighs between 400 and 550 grams depending on the size of battery and wing configuration that I use __ Contact: r dot p @ webone.com.au

Remote shutter (or 'cable release') for SLR & DSLR cameras The cheaper Canon DSLRs, among other cameras, have a simple 2.5mm stereo jack socket for the remote shutter release, with a standard pin-out: __ Designed by © Chris Johnson

Remote TV Camera Power A while back I received an email from a company with a problem.  They needed a security camera installed at some remote location.  The camera was a high quality color camera sending out standard NTSC video through a long 500 foot 50 ohm coax cable.  With some difficulty they got the coax strung.  They were told that there would be AC power near the camera location to power that device.  But, they then learned that in fact, there was no power available.  They thought about using a solar panel and a battery but they decided to call me for help instead.  Was there some way to power the camera without stringing another cable? . . . Hobby Circuit designed by Dave Johnson P.E.-July, 2011

Safe Flash Trigger for Your Digital SLR Camera Many of today's digital SLR cameras risk serious damage if used with an external electronic flash, whether that is a portable type or a large studio "strobe".  We found this was the case here at SILICON CHIP so we have produced a flash trigger to ensure the camera's safety.  You can do likewisebut beware of the JISP!___ SiliconChip

Security Camera System Mods It's hard to beat a modern digital recording system that saves video and audio to a hard drive, either within the unit or on a networked computer.  The software usually comes with the ability to sense motion which is great for saving disk space and making it easier to find interesting content.  But, those motion detectors are notorious for not working well, especially when uninteresting motion is in the frame. __ Contact: Charles Wenzel of Wenzel Associates, Inc.

Serial Cable for Casio Digital Cameras The "LCD2LPT with Lirc" circuit is the compilation of two circuits found on the net on a single board.  The first is LCD to LPT interface and the second an IR remote control interface using http://www.  lirc.  org program. __ Contact: IQ Technologies

Serial cable for Casio QV-200 digital camera Lose your cable? Build it yourself and save $29.  Fits many QV models __ Designed by Bob Blick
