Various Coils (Pancake Coil Circuit) 003

what is imbetween the cds keeping them apart?

[ShawnHydedotcom]

flat tesla coil, just proves his wireless power theories.

Love your tool-using-human low budget switch.

[maddfix]

the most inefficient transformer...what's so cool about this?

[blaargenheimer]

Is that a bifilar?

[handsupbud]

Sounds like a baby SOS from the Titanic.

[DidntKnowWhatToPut1]

how did you not fry the transistor on the flash bord? I have burnt out far to many to be funny >_>

[kubikop]

Try using an AC Capacitor instead of the DC one on the board.

Hope this helps....

[computersolutions164]

Stick a diode on the output of thetransistor Collector to emitter

then you wont blow it

Always have great video's up Kubikop thanks for sharing. I was watching a movie called the Time Machine today and I was wondering where the inventors or tinkerers have gone to ;) Watch and you will see what I mean. Anyway funny that coul reminds me of human fingertip fingerprint for some reason.

[kubikop]

I kind of get you cause its not wrapped too linear, anyway thanks I love tinkering as you put it.

Thanks for finding it interesting...

i have a pair of wireless headphones that use this technology. I think. Inside the headphones is a rechargeable battery and a small 1inch diameter coil. The larger coil is in the carraige. You have to put it on top just like you did with yours. You can put anything in the carraige that is metal and reaches from the end of the larger coil to the center. Just thought I would share.

[kubikop]

Thanks for sharing..

i wouldnt think this is the best way to do it

[kubikop]

Yeah Im going to use the PIC with a full bridge Mosfet rig. But the camera flash was just looking at me ;-)

Im surprised it worked at all as it was not even at its Resonant Frequency. Im going to run with it for while I build my IRF720's onto a big enough Sink for the heat.

Unless you can think of a better or easier way?

I am going to build another coil with the same dimensions as the previous one If I can....

any thoughts welcome ;-)

[elecbeg]

Im just wondering if you cap is in parallel or series to the coil?

If its in parellel, then you want to stay as far away from resonance as possible, as that increases impedance, which lowers current, which lowers the power transfer from one coil to the other.

If its in series, then yea, hitting resonance would give you huge more power in your second coil as it would drop your impedance down to near 0, which means max current, which means max power transfer.

[kubikop]

Yeah, its in parallel at the moment, but I could change it to get better efficiency....

anything with a pic in it must be good!. ive got a pic16f84a i wish i could get some premade programs for it :P to make it do certain functions so i can learn how it works

[elecbeg]

There are loads of premade programs on the internet for pics. A lot are for the 16F84 aswell as its a old pic that most people learn with. If you do a search for pic tutorials, they all should supply basic programs, and how they work.

[rroge5]

realy?

[elecbeg]

I have a few of the websites saved in my favs for pic tutorials( all 16F84 ), if you want them. It wouldnt let me post them on here, so your gonna have to pm me your e-mail address if you want them.

[kubikop]

@rroge5 ill send you a program if you want and the spec sheet....

Paul..

[rroge5]

that would be cool if u did

[kubikop]

PM me your email address......

man i remember getting shocked by a camera cap i think it was 400v plus it was a big cap my hole arm went num for like 2 minutes lol but it looks like your going with my phone idea lol i got one that i might give you its a samsung camera phone but i dont know how much is shipping

[kubikop]

I would welcome it if you don't mind, I could send you something you want and we just do a swap if you want could not cost too much to send a Mobile.

I might have the capacitors you need for you LCD TV?

PM me...

Paul..

[30GB]

well i fixed that lcd long ago but if you could maby you can make me a circuit that is used on batteries 12v to burn out the crystals by zapping them

[kubikop]

what do you mean by that and I will create it?

[30GB]

never mind ill try to send you it just mail me your address and ill see at the post office how much is to ship it overseas

[kubikop]

Ill PM you it. ans give you half the postage...;)

I have a flash i dismantled years ago , from an slr camera . I put a connection block on it and 3 bent sewing pins ,, negative , positive and the trigger wire .. I got them real close to the middle pin and when i trigger it it makes an awesome bang .. Makes yer ears ring !! (and blows the pins to pieces bit by bit)

[kubikop]

yeah, it will do that...lol

I want to make a nice little spark gap but I might need to double the voltage first..

[ZED74]

the interesting thing is the one i have is like 10x louder than any one i've seen here on youtube . It makes ya hesitate before pressing the button , i would say its as loud as a small french banger !! i suppose the ones for slr cameras have much more power !

[kubikop]

Like a Peugeot or a Citroen? They do make bad cars... Oh sorry why do you not make a video now so we can see and hear what you mean.... It would make sense....

Paul..

ps looking forward to seeing a video from you.....
