flashing circuits found in flash for disposable cameras -
You are going to like this project. It costs less than $3. 00, contains six BUILDING BLOCKS, re-cycles a
disposable flash camera and you are going to learn a lot about electronics.
Everyone has seen a disposable flash camera. . . . [email Colin Mitchell: talking AT tpg.com.au]
9v Powered Xenon Photoflash
Controller - This 9v battery powered circuit is
designed for remote control flash needs. A charge control circuit turns off the high voltage generator when the
photoflash capacitor is fully charged. A neon lamp is included to indicate when the system is ready to flash . .

A home-made light-operated camera
trigger using the stamp microprocessor - 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. . . . [© Mark Harris 2010]
A simple home-made light-operated
camera trigger - This device is a very simplified version
of the original CamTrig. It has only 3 electronic components and costs less than $5 to build, but has some
limitiations. . . . [Mark Harris Photography]
("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 digicam - a
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. . . . [Copyright © 2007 Tom Lackamp]
AN34 ZXSC100 Power Supply for Digital
Still Camera - Zetex Semiconductors Applications Note:
Presented in this applications note is a typical sytem power supply design for a digital still camera. The
solution is based on ZXSC100 DC-DC boost converter which provides an efficient and cost effective design.
Conversion is from a two cell alkaline battery, 3V to 2V, to a regulated 3. 3V output with a maximum load current
of 100mA. All performance graphs associated with this design are provided in application note. . . .

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. Whenrocket reachestop ofrodlaunch lug knocksclip off, openingcircuit,
which is sensed by a device which triggerscamera. This worked reliably, and hasvirtue of simplicity. But, it had.

scheme uses CCD shutter - 07/02/98 EDN Design Idea (File
contains several circuits. Scroll to 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. . . . [by Giovanni Romeo and Sandro

Build yourself a Witness Camera - The Witness Camera is an automated, self-recording surveillance camera, that uses a
gigabyte-class flash card as recording media. I designed the Witnesscam because available surveillance solutions
were too expensive or impractical for home use. I built the system from a VGA CMOS colour camera, a
passive-infrared (PIR) movement sensor, an ATmega32 processor, and a 1GB SD-card
