it looks like the 555 timer sets the time base for voltage "stepup
coil". Some call this thing a kickback regulator. The cool thing about
those is the same circuit can develop any voltage either above or below
the supply voltage. it looks like trigger timing is adjustable, but no

Here's an alternative to making or purchasing expensive strobes. I was
looking at these when I almost became a KR owner two years ago. This
companies carries a lot of neat light (including light-weight and low
profile) options that could be adaptable to aircraft.

Not so when charging a cap to oh say 400 or 500 volts from a 12v power

On the KR I owned in South Africa, I did just that: used house alarm
strobes, which are extremely cheap and easy to find. The same strobes are
also used on industrial machinery as an indicator of the machine condition.
The ones I used had a perfect flash rate (1Hz, that is 1 flash per second).
I di
I was a pro shooter for the nation's longest continuously running news

25 years ago, but then the other factor was the duty cycle of the xenon

The time to charge a capacitor is given by the RC time constant. It is limited
by the power rating of the resistor. The inductor is used to limit the current
to the flash tube and/or combined into an autotransformer for a final voltage
boost before the flash. Triggering is done differently on di
I realize this is an effort to save money, but trying to reinvent the wheel
(strobe) is a lot of effort. If you want strobes and cheap ones, go to hide
away strobes for police and fire. They are cheap, 12 volt and light weight.
Problem solved!

Changing the flash rate may not be easy. often the flash rate is
simply the amount of time it takes to charge the capacitor. If you
reduce the capacitor size, it will speed up but then there is less
