Use for the Tesla Switch

[Turion]

Thanks Matt.
Glad I asked before I wound it. I didn't see anywhere in all the previous info that it mentions putting the coil together this way, but now I know. And I bet I've read through this entire thread at least three times now, which doesn't include going through and cutting and pasting your comments into that word document I made. So if I don't know something, it's not because I haven't done the reading, just a lack of understanding or poor memory. That happens when you get old.

I may not get much done today. My power will be cut off any minute to switch my electrical panel out to a 200 amp service. The house is about 90 years old and I am redoing all the electrical wiring and starting with a new panel, Everything in my basement shop has been running off one extension cord and the first order of business will be to wire it for lights, switches and wall sockets. I'm kinda excited about that. I've had a power strip plugged in with all kinds of short extension cords hooked up to it, using one for lights and the other ones to go to tools, but only running one at a time so I don't blow the 15 amp breaker, which also serves another room in the house.

Finally I will have a shop that actually somewhat resembles a shop.

I should have the transformer wired up by tomorrow. I thought about it a lot last night. I can see it is going to be a challenge. I'm making sure all the rough edges are taped with teflon tape before I even begin. I don't want to have to redo that job!

mbrownn,
Thanks for the advice. If there is one thing I do, it is follow directions. If Matt tells me to buy a purple spotted cow, I will be on the internet searching for one. Some of this he has left to our imagination. He just said switches. Relays can be used as switches, transistors can be used as switches, etc. If he had said get a specific switch, I would have ordered it already. My problem is, the more I'm on my own for this stuff, the more likely I am to screw it up. My experience with electrical is limited to wiring houses. That's why I'm so excited that Matt is the one who came up with this. He actually gives a crap that people are able to duplicate his stuff successfully

I haven't built a Tesla switch but from what I know works in devices that use a similar component, I can tell you that this is very important. The transformer has to be very low resistance yet have sufficient inductance to work efficiently. If your resistance is higher the frequency of your switch will have to be higher and your output will be lower. If your inductance is too low your output power will be low. It is a trade off between one and the other. Follow Matts instructions to the letter and you have a good chance of making it work.

Just make it one section and wrap all the wires together. Use razor knife to score plastic and break it off.

Matt,
There are two separate sections on this transformer. Do the two short wires go one one section and the longer wire on the other section? That is the way I planned on winding it, so want to make sure I don't screw it up from the get go. I assume they should all be wound in the same direction also.

Wind the transformer with #20 awg. I am not sure off hand how much you'll get on it as far as footage but make sure 1 wire is 20% longer. So if you can fit 3 wires at 10 ft then make sure the 3rd wire is 12 foot. Follow ME?

Make sure you mark that wire aside from the other 2. Make sure you mark the the start and finish of all wires. If you don't you'll have a fire.

I'll set you up a circuit for the MJL's. Post it tomorrow.

I have one (1,000 ft) spool of #20, two (1,000 ft) spools of #23, and one (1,000 ft) spool of #26
I've got a bunch of transistors for Bedini projects 30 of the MJL 21194
Several from Radio Shack:
2 of NTE 331
3 of the 2N3904
3 of the TIP31 (40 volt 3 Amp 20W dissipation)
45 NPN that I can't see a number on
their h
/fe is 200
Vce 30v
Ic 800mA
Power dissipation 1.8W

But I will go buy whatever I need. That's just what I have lying on the shelf.
The relays I had ARE mechanical, so that's out. But the store is close. Fry's Electronics and Radio Shack both.

I thought I would start winding the transformer however it needs to be wound while I order the rest of my stuff that I can't just go out and buy.

OK Matt,
Got my handy dandy Radio Shack transformer unwound and ready to be rewound.

There are two sections on the transformer. I know I am to use three strands of #20 magnet wire for this, but in what configuration on the transformer? I also know that at least one of the wires has to be shorter. I have read back through the notes, but all the actual references to lengths I can find apply to the bigger device, and are using #14 wire, so I am unclear as to how to proceed.

Oh, got my Stamp kit today too, so all I need are some switches and I'm set. Thought I'd use 20 amp relays until I find some switches for this that will work correctly.

David Bowling

What kind of wire do you have handy?

Are the relays mechanical? Mechanical relays will not work. Do you have and transistors handy?

In the beginning....

I do not have any videos as they do not show much. I am putting together instructions on how to build several sizes of this TS. Later once few replicate I will give out the complete details on how to rotate batteries for long term use.

The transformer is used to collect the normally wasted magnetic energy on the wire and use it as current.

That build is mine. The out put is 3000watts. Matt was vary kind in helping me getting it to work!!! I hope to post some test soon. I did not used the right wire so I have to wind it again with #6 transformer wire. Matt is right about the heat in the transformer so use what he said to use.

The caps I used are 18,000 uf x 7=126000uf

Wow, I'm trying to understand what you guys are doing and so far it looks great!
@Rosehillworks -- it's not clear to me yet why you need a transformer... can you explain its function? and what type you needed?

@Matt, I look forward to your detailed plans -- and what is your most recent video on this? Hey, thanks for this adventure and the progress made.

[rosehillworks]

Matt
Thanks. I will do that.

[Matthew Jones]

Matt
That is what I did. I was just running the load. (just wasting the power and putting nothing back)
Or did you mean just run it on the battery's no tesla switch for the baseline?

Ya NO Switch at all. Run it for 1 hour see what you loose. Next day run the switch for 1 hour see what you lose.

Cheers

At all
after an eight hour run on two 55 watt halogen lights, and the transformer putting out about another 150 watts of heat, because I used five strands of #20 AWG for L1 L2 L3 (DO NOT DO THAT) Battery 1 lost .25v
battery 2 lost .13v battery 3 lost .26v battery 4 lost .16v. So use #6 square wire on the big one!!!!!!
All four battery's in the test where 105amp hour's each.

Make sure you get baseline by just running the loads on the batteries straight.
