Dark Room Timer  This is a circuit for darkroom timer that can produce musical tones after an interval of one second. __ Electronics Projects for You

Darkroom Test Strip Maker I bought my first serious camera (an Olympus OM-10) in September 1990, and for a few years after that was fanatically into photography.  By December 1990 I had a darkroom outfit, but I could only use it when I was at home at my parents' on summer or Christmas holidays.  It wasn't until 1992, when I moved to where I still live in 2003, that I could set up a permanent darkroom (also known as a laundry room) __ Designed by Markus Wandel

Darkroom timer using PIC16F84A Yet another darkroom timer using a PIC 16F84A 4 mhz.  I tried to design a timer that would do everything it needed to do but with the smallest number of pieces and simplest mode of operation.  It only needs the PIC, a four digit LED display, one other IC, a resistor network, one pushbutton switch and a capacitor.  It can run on batteries if you use a solid state relay to turn the exposure light on and off thereby adding a minimum of parts to make a fully functional darkroom timer.  A simple regulator would add only a few extra parts and allow the use of a "wall-wart" for power __ Designed by Lloyd Gordon

Darkroom Timer v2.0A for PCB Exposure Box This is an improved version of the Darkroom Timer originally created by Stan Ockers (1999).  Some extra features were added and the PIC code was modified accordingly __ Designed by Vassilis Papanikolaou

Day / Night Sensor For daylight or night-time disabling.  For use with the "basic timer", the "not-so-basic" timer, and other circuits. __ Contact: archilochus57 @ yahoo.com

DIY intervalometer based on Arduino I would like to share with you my Intervallino project with all the steps and details it involved.  When I started looking for similar projects on the web I found extremely useful to have a look at either the circuit schematics or snippets of code or even soldering videos!   For this reason I try here to be the most complete and precise that I can, so to give some hints and ideas to anyone willing to make a similar project. __ Designed by L

DIY intervalometer for Sony NEX 5N camera I decided to make a DIY intervalometer for my Sony NEX 5N camera so that I could do time-lapse photography.  This intervalometer should work with most Sony cameras: NEX, Alpha and other.  To work intervalometer used infrared LED___ Solderer.TV

Electric Shutter Release for Cameras Commercial remote shutter releases are usually expensive.  Here's one you can build for just a few dollars.___ SiliconChip

Electronic shutter release with ultrasonic remote control 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

Flash Slave Trigger Flash slaves are used when you need to supplement1-flash unit with1-or several more.  This slave trigger simply triggers those other units.  It does this by "seeing" the first flash (using a phototransistor) and triggering the other flashes a few microseconds later.  The sensitivity of the circuit is adjustable to compensate for ambient light or dimmer than usual master flashes. __ Designed by Aaron Cake

HomebreW Wired Remote for Canon EOS 350D Camera This article provides details on building a homebrew wired remote for a Canon EOS 350D digital SLR camera (known as the EOS Digital Rebel XT in some markets), using a two-stage push button switch to provide functionality of the camera shutter button. __ Designed by Martin Pot

Homemade battery packs for Canon S100 digicam In January 2001, I had just received a Canon S100 "Digital Elph" camera for Christmas.  This camera was, and still is, a marvel of miniaturization for what it does.  But a serious downside of the small size is that the batteries don't last very long.  A brand new battery pack will operate the camera, with the LCD viewfinder on, for about an hour, but after a couple of years' use, that same battery pack will give less than 10 minutes of such operation (although it may still take a hundred pictures if used carefully with the LCD mostly off) __ Designed by Markus Wandel

Home-made light-operated camera trigger It is more expensive (around $150 for parts instead of $30), but is easier to construct, and vastly more flexible since it is based on a programmable microcontroller that can have new functions downloaded from a computer instead of having to build with more hardware. __ Designed by © Mark Harris 2010

I Spy with My Little Eye.. Peer into hidden nooks and crannies with this tiny ionspection camera built into a flexible wand.___ SiliconChip

Infrared remote control with intervalometer function for Nikon cameras This project is the natural evolution of the “standard” version described in the previous page.
The idea is quite simple: we have a micro capable to trigger the camera, why not to program it to shoot a picture, automatically, at a regular intervals? __ Designed by Michele Bighignoli

Intelligent Video Switcher Monitoring several cameras on one monitor is usually done in one of two ways:  divide the screen into sections and show them all at once, or time sequence the cameras onto the whole screen. __ Designed by Luhan Monat-Mesa Arizona

IR Remote Control for Nikon cameras, standard version This is the first circuit I created.  Working principles are described in the "Basic Info" page.  The transistor connected to the led isn't really necessary, but I prefer using it to get maximum power.  The Pushbutton SW1 is placed between the battery and the ground, so that it is possible to use a transistor in open-collector configuration to turn on the remote control.
It's just like the original Nikon ML-L3 remote control (slightly bigger, but I have already explained why I haven't used SMD components) __ Designed by Michele Bighignoli
