Camera Flash Update

A video update on the Camera Flash Unit and Tesla Tuned Coil Circuit that can be found in any 35mm "chuck away" camera. Showing the circuitry in detail, the flash unit being charged and what happens when you touch the contacts of the capacitor!

I didn't edit the video very well I left in quite a lot of spaces of inactivity and "fumblings" which probably would have been better on the cutting room floor? So in that respect the video is quite long, however the message is clear and the music is good! So enjoy the experience anyway...

This video is dedicated to my friend Sam as we could all use a little inspiration sometimes :)

The simple circuit can be found on google this is a good example http://www.repairfaq.org/REPAIR/kflash.gif

I found this information when googling for "tuned oscillators" :-


"Higher power photoflash with SCR trigger operation...


1. The tripler consisting of D1, D2, D3, C1, and C2, boosts the AC line voltage to about 420 V. This charges the energy storage capacitor, C3 through R2. R1 limits inrush current to the tripler.

2. The trigger capacitor, C4, charges through R3 and T2.

3. The neon bulb, IL1, signals ready by coming on when C3 is charged to about 360 V.

4. Applying a positive edge between Trigger + and - turns on the SCR which discharges C4 through T2 generating a high voltage pulse (5-8KV) which ionizes the xenon gas in the flashlamp, FL1.

5. The energy storage capacitor discharges through the flashlamp. R2 limits current from doubler to allow flashlamp arc to quench.

6.Flash energy is about 45 W-s. Adjust component values for desired application.

7. CAUTION: Line operated power supply is not isolated - use with care."




...a 5 to 8 kilovolt pulse form a standard 1.5volt AA/AAA battery!

You should check out the user Chilliqueen2007. He demos a stripped-down flash experiment and lots of other cool simple demos.

@User2718218 ok thanks for the info :)

[MattBlytheTheOne]

Thanks for the information!

I looked up Wiki and this watt I found:

"The energy (measured in joules) stored in a capacitor is equal to the work done to charge it." Although the math is not that simple!

And I thank you for the dedication :D *HUGS* :P

I'm still working on the Rod Stuart number ;)

Thank you! that was educational.. now time to open up my old camera !

[Drevtoobe]

The energy in a capacitor is proportional to the square of the voltage. So if the cap is charged to 100 volts it is storing 10,000 times more energy as compared to when it's charged to 1 volt.

I always love your soundtracks. Heh heh. Nicely elaborated.
