Complete Strobes Easy to Build!
Build a working self-repeating strobe from a disposable camera, a camera
flash board, or from scratch with some help with various fluorescent lamp
DANGER - Shock hazard, possibly fatal shocks if you get zapped by
photoflash capacitors or outputs of line-powered fluorescent lamp ballasts
or line power itself.
DANGER - There is a lot of talk that it takes 10 joules of capacitor
energy to electrocute a human, but there is significant scientific opinion
that lesser amounts have some chance of killing people. Critical variables
include skin moisture level and distribution and also what point of the
heartbeat cycle one's heart is in if a shock occurs.
Please read the shock hazard / safety parts of:
My Xenon Safety Page. At least look at the
cute modified photo of a shock victim!
Sam Goldwasser's Strobe FAQ.
Hack a Kodak Max Disposable Camera into a
Strobe! NOTE - This approach to homebrewing a strobe is recommended
mainly for ability to run from a single 1.5 volt battery. If you can
use a higher supply voltage, there are better ways to do this. NEW FILE

Electronic Goldmine (800-445-0697, 602-451-7454, http://www.goldmine-elec.com)
sells a complete flash board with the catalog number G4587. I tested one
and it works, despite having so few parts that I was afraid it was
incomplete. It takes one AA battery in its battery holder, with positive
towards the board. On the solder (green) side of the board, there is a
spring that must be connected to an obvious square silver-colored contact
on the board for the inverter to work. Two red wires coming from the board
have some sort of trigger contact attached to them - merely short these
two wires together to trigger a flash.
Strobes Using Fluorescent Lamp Ballasts
Sorry, no complete plans yet. Ideas are available in:
My Fluorescent Ballast For Strobes Hints Page.
Strobes Using Available Compact Inverter Boards!
NOW AVAILABLE 11/10/2000 - Strobe using a JKL Lamps
inverter board available from All
Electronics or Digi-Key.
strobes using easily available inverter boards so compact as to almost be
components! These inverter boards include ones marketed for powering JKL
Lamps brand miniature cold cathode fluorescent lamps. Such strobes can be
usable in model rockets.
If this already gives you ideas, beware of just one little bug - ordinary
rectifier diodes may not work well at rectifying high frequencies - use faster
types of diodes. Digi-Key has several kinds that are good for this.
