RLC Resonant Circuit - with Disposable Camera Parts

[100roberthenry]

i don't see how you wire the bulb?????

[100roberthenry]

can i use npn 2n3904?....and what size cap?....thanks man..

[MrDdogg42]

hi can you use the transformer from a old cfl to make this. also why haven't you used the second transistor this time cheers

[chilliqueen2007]

@MrDdogg42 This circuit was engineered by Kodak and /or Fuji. It can only have one transistor.

[Slovenija12345]

what transistor and capacitor can i use???????please answer

[ImmortalAcorn]

Is there any way to make this without the center tap transformer?

[iamzid]

i went ahead and put one of these of my own together. that little thing was putting out just over 1000V!!! like "WOE!!" too bad i had it sitting on a spiral note book and it arced out to the spring. after that it only put out 35V. oh well. it was still fun to do, and hay i learned something. do not place random metal pieces next to you HV project.

[ImmortalAcorn]

@iamzid Really? What resistor,capacitor and battery did you use to get it this high? Did you make your own custom transformer?

[iamzid]

@ImmortalAcorn i just followed the instructions to the letter, i think.... the camera i used must have had higher ratings or some thing. or i just did it wrong and the voltage was running errant, i don't know. i doubt that it was pushing to many amps. but i did not have time to test it before i destroyed it... :( the transformer was about the size of a green pea so its not surprising that it fried.

Thanks very much for your great work.

Have made this circuit, sorry to say it only flashes, can you say where I’ve made a Boo Boo please ?

what if i do not use a 20 ohm resistor? it was not listed in ur initial set up at the beginning of the video.

[chilliqueen2007]

@shinobi1014 The circuit will not work w/o the resistor which BTW is 220 ohm not 20 ohm.

[shinobi1014]

@chilliqueen2007 i know... typo

[shinobi1014]

@chilliqueen2007 ive tried it with a 220 ohm and it didnt seem to work... Red-Red-Brown-Gold correct? thats 2-2-multiplier 10- tolerance +-5% no? cant seem to get it working. any tips? i get my parts out of a disposable camera but the resistor was from a TV.

[chilliqueen2007]

@shinobi1014 , The problem is not the resistor. It is the mini-transformer. Every manuf. has its own winding configuration. Are you using a 4pin or 5pin transformer?

[shinobi1014]

@chilliqueen2007 im not so sure the problem is my transformer. 4 or 5? that is an odd question. almost as if you suggest i can not tell the difference between 4 and 5... im using the same camera board as in the video. its a 5 pin. i wired it exactly like the video. i have over 30 something cameras i got from a photo shop (free) so i have plenty of parts but most of them are 4, 6 and 7 pin. i managed to find only 3 5 pin and so far, desoldering em, i broke them.

[shinobi1014]

@shinobi1014 im down to one left

[chilliqueen2007]

@shinobi1014 The reason I asked U 4 or 5pin is that all the transformers comes in 4pin or 5pin config. Anything more than 5pins are the anchoring points on the board and R not part of the circuit. U might want to try the 4pin transformer which is actually easier and not prone to error. It uses the chilliqueen 2 transistor circuit. If UR interested I will provide you the instructions.

[shinobi1014]

@chilliqueen2007 sure i would appreciate any help you graciously offer. btw i have been desoldering parts and storing em in film canisters so i can have my own surplus to make lil gagets. i really dun wanna keep using the big bulky boards in my charger projects. maybe u can help me. once i get the mini charger, how would i step up the 400v+ to about 900? and i mean without the use of a flyback.

[TechnomancerMorhion]

What if I use the larger capacitor instead?

[chilliqueen2007]

@TechnomancerMorhion This circuit will not work with an electrolytic. You can use a mylar cap but you will need two diodes between the cap.

Great video!!!

[jeannacav]

This is very clear. Great job. Thank you.

[DiyEcoProjects]

wow! simple... going to give this a try, thanks mate

[tectalabyss]

Great !! 5 stars. Thanks for sharing. Tec
