New comer needs any and all help

great video, and explanations. i do have an old tv set i took apart, but not sure what parts your talking about and how to use them to do what... sorry but i am a completely ignorant to alot of this stuff.

sorry it has taken me so long to get back for some reason i stopped getting emails when i had a reply. dont know what the deal is.

but basically if i am right base on what your saying, i can not get any more power, voltage or amps from just more windings right? and as far as you know adding a third winding dont do anything as far as more power either? and i can just wrap a 3rd wire around it and get power from the two ends right? they must be hooked to something correct?

as i said i have an old tv and many parts. i would love to make what you made with some power like that. but i would need alot more than the diagram.

Well, for the high voltage above all you need from the TV is the flyback transformer. It's the scary looking thing that has a heavy wire going to a suction cup on the picture tube. Be sure your caps are discharged! Look on the internet for some basic info about flyback transformers. You'll just wind an 8 turn primary, with a center tap, on the "handle" of the flyback, and use what is already there for the secondary. The rest of the stuff in the diagram you can get from just about any electronics supply store except Radio Shack.

No problem, I think some of the software settings in the forum have been changed. Just go into your account settings and re-select email notifications, if that's what you want.

Not quite. I believe that you aren't going to get any more _energy_ out than in, or _average_ power, but you can certainly get more volts, or more amps, or more instantaneous power, as the video above shows. It's a matter of the ratio of turns in each of your windings, plus taking advantage of what is called "voltage rise by standing wave resonance". It's great fun, too.

Lots of people have videos on YouTube fooling around with TV flyback transformers and car ignition coils. You'll see circuits very much like the Bedini motor with a 2n3055 driving the primary, you'll see oscillators based on the 555 chip, and many other variants. This one, based on Royer oscillator induction heaters, is the best and most reliable I've seen. I have not yet blown a single mosfet using this circuit or the inductive wireless power transfer system variant, except once when I mistakenly switched on with no load attached at the output.
You can watch those YT videos and learn a lot. Just be careful, these things really can kill you if you take the output shock across your chest.

i really like the idea of that last plan you gave me. it seems like just what i am looking for. although i am confused by it, i have no idea how to follow those plans or even what alot of the parts are, i see the capacitor, and resistors, power input and coils, but other than that i am LOST!

Well, other than the parts you mentioned, there are two mosfets (transistor types, the Q1 and Q2), two regular highspeed highvoltage rectifier diodes, and two Zener diodes (the ones right next to the transistors are actually inside them, not separate parts, so don't worry about those). Add a switch, a fuse, and heatsinks for the mosfets. I also used screw terminal blocks to connect the mosfet legs, but you can just solder them in place and save two dollars.
About ten or twelve dollars worth of parts all together. The mosfets are common types, as are the rest of the parts. The hardest part of this circuit is finding the right secondary ground pin on the flyback transformer!

I'll post some pics of the layout of my driver board in a little while, check back in a couple of hours. It should make sense to you when you see the actual parts laid out on a board.

ETA: Don't forget, with the flyback transformer hooked in and working, this circuit can KILL you, or your cat or your child..... so please, be very careful, don't have scattered clipleads all over the place, and know where your cats and children are when you are experimenting. If Tabby jumps up on your bench to check out the sounds or something ... you might get a fried cat for your trouble!

well i dont have a mosfet or even know what it is. i am just going to try a traditional JT with a big toroid the plans you posted a few post back, and 10t 18g primary and 100t 26g pickup. i am really just trying to provide enough power to light up a light bulb, would be nice for a small appliance. so im am in the process of building what you posted that powered your neons but with a different number of turns and different gauge, also i prolly will use 9v instead of the traditional AA. what do you think?

also how do i know what transistor to use, and if i use one that works how can i know that is the best one to use?
