3 Xenon 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….(electronic schematic /

AN34 ZXSC100 Power Supply for Digital Still Camera - Zetec
Semiconductors Applications Notes 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. (app note added 2/06)
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 to top of metal launch rod.
When rocket reaches top of rod launch lug knocks clip off,
opening circuit, which is sensed by a device which triggers camera. This
worked reliably, and has virtue of simplicity. But, it had.... (added

Automatic-exposure scheme uses CCD shutter - 07/02/98 EDN-Design Ideas This
application follows the Design Idea, “Peak detector maximizes CCD-sensor range” (E D N,
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....PDF has several circuits, scroll to find
this one.... [Design Idea by GIOVANNI ROMEO AND SANDRO RAO, ISTITUTO NAZIONALE DI
GEOFISICA, ROME, ITALY]
Batteries charger & PSU-ideal for Digital cameras - This circuit was created for
digital cameras. It's known the digital cameras have considerable power consumption. For
example my camera Minolta E223 requires….(electronic design added 08/08/08) [Site is under
construction right now]
Build a simple one-chip phototimer - 8-Jul-04 Issue of EDN Recently, I
needed to automatically switch on a lamp when it became dark and keep it on for a given
time. Trying not to reinvent the wheel, I looked through what was available on the market,
but I could not find an inexpensive device that satisfied the requirement. Some products
worked like a photoswitch, lighting a lamp when it becomes dark and keeping it on while it
is dark—in other wor.... [Design Idea by Abel Raynus, Armatron International, Malden, MA]
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....(design added 06/05)
