Camera Flash Stepping Up Transformer

I wanted to take a look inside a "chucka" (chuck-away) camera to see how the flash worked. To my amasement I found a 1.5v standard AAA battery, a transistor, two small transformers/inductors and a capacitor. I wondered how a small 1.5v battery could be "stepped up" to the extent that it could power a flash unit, heat up and even give a reasonable electric shock if you touch the contacts!? I also wondered why there is a whining noise when the flash unit is switched on?

Further investigation revealed the electronic components configured in a simple operational amplifier and Tesla Tuned Coil circuit...

The circuit "whines" when the flash is switched on because the resonating coils in the Tesla Tuned Coil circuit are finding their optimum operating frequency.

When the circuit is "tuned" the stepped up voltage is suffucient to power the flash unit.

Incredible technology and incredibly simple!

I am wondering what else this technology could be used for?

I am hooking a 555 timer chip up to the hold down button and have it pulse the 1.5volts into the capacitor (Tap) into the capacitor then use another 555 to discharge the cap into a 300 volt capacitor and then keep taping using 555's into larger and larger capacitors using 555's, reed switches and other step up transformers.

At some point we boost the amps as we continue to boost the volts and when we do we can expect to run our cars and homes on rechargeable flashlight batteries.

@HFCOILCOMPANY Well that would be a great idea. The point is if we can continuously charge the battery with radiant energy.... it just might be possible :)

SHit!!!

literally just through out an old flash camera !! :/

@969SobiasTokeS696 lol you can buy old ones with out of date film on Ebay really cheap :)

Great videos, one of the few technology explanation videos that didn't put me to sleep halfway through :p Thanks for sharing!

@Tanksta3 Hey thanks Tansta! You're welcome. Have a great day :)

@MattBlytheTheOne oh :D yeah! I forgot its similar but not same.

[MattBlytheTheOne]

@awesomelightning well there are three coils in the circuit, check out my video "Camera Flash Update" and in the description you can see the circuit diagram, although not all flash circuits are the same :)

[awesomelightning]

@MattBlytheTheOne i thought it was three. That's what it said on that "Deconstructed" episode.

thank swat I thought :)
