Thats the address but the picture is showing for me.
You already have the picture though.

Oh yeah, I definitely have this picture! This is the setup I am building now with my large transformer I just rewound with 8 wires Matt designed feet drivers for this setup and I had those boards made and have tested them. They work great. I hope to have mine ALL put together shortly. When Matt says you need 10,000uf to 20,000 uf caps at 100 volts, he means it. Anything less is likely to go boom.

Guys, really been enjoying reading all the thread we started winding David's stuff over the weekend (240volt version) but wanted to see if we could get any thing for Matt going.
Just a quick test from i think is now the old one here (not the scalar charger)
Still learning , we got heat from the transistor, we used a 2N3055. Not sure what transistor is recommended, but it appears it is an NPN type. We did not have a heatsink, maybe we could try paralleling more transistors if necessary. The transistor got hot very quickly when we connected the power.
still a bit behind and guessing that the 1 ohm 100 watt resistor is for if the dead battery is of a high impedence, that the motor can still turn,1 ohm seems quite a low impedance. The manual switch causes the motor / generator setup to run slow in one position, fast in the other position.
will get a snap up later. We used a clamp ammeter and measured around 5A
For the batteries.
started out with Good battery: 12v 1.2AH (will have to use larger batteries)
Bad battery: 18AH, also tried only capacitors.
any how just wanted to thank Lid, Luther , Dave, Matt and you all for the best thread going ATM. Will have more stuff for Dave's later.
Edit, new one from Matt, love ya brother will have a go at this too.

I'll explain it later. If you have the parts to build it chime in. If you don't and need some let me know I can provide info on drivers and fets.

ehsanco1062,
The reason I knew about the schematic before Matt posted it is because he and I talk all the time, and I have known him for a while now...since I built his simple motor and probably drove him crazy with questions. Sometimes he tries things out on me to see if they are idiot proof...because if I can do it, ANYBODY can. That's no lie either! So when Matt built his next to last circuit and it was so successful, he improved upon it, and I have been messing with the improved circuit. Matt designed (and I built, with a lot of help from him) some generic driver boards that will run the fetts on this circuit. So I began working on winding my transformer with 8 strands shortly after Matt posted his previous circuit.
I used the big transformer I ordered to build the big setup Matt showed in the "Use for the Tesla Switch" forum. It took 8 strands of #18 each 40 feet long.
You are right about wires everywhere. That's why Matt designed boards for this setup. I ordered them and then soldered all the parts on and have been running with them on a smaller transformer, one about halfway in size between the one he listed in the previous schematic and this big one that i was winding. You will have to talk to Matt about getting the boards. They cost, but they can also be used on lots of different projects so I felt like they were WELL worth the cost and they make life so much easier!
No secret conspiracy here. Just trying to make sure things WORK before wasting people's time. We don't sit around and think of schematics for other people to build to show how smart we are. We BUILD them first and then show you the ones that work.
All the parts on the control boards are also on this schematic. I have that parts list somewhere. I'll look for it.
If I'm not mistaken, R1-R9 depend on whether you are running this with a STAMP or some other microprocessor.
I think I have those values for the STAMP, which is what I am using. Matt is using something else, so he probably has the right ones for the Propeller, which is what I think he uses now.

I just wanted to make sure someone was ready to build this as opposed to just looking.
These files are for ExpressPCB
Right click on a part in the schematic and you will get the DIGIKEY part number. Most of the schematic above (SCC 1.0) is covered by this driver schematic.
MAYBE DAVE YOU POST A PICTURE OF HIS FINISHED BOARDS.
Anyway the Fets in the schematic can be just about anything 300v to 1000v at or about 50+ amps. You decide.
The caps (C1-C2) are 10000 uf 100v or bigger. You do not want to use little caps in this spot they will blow and you will get hurt. Big is good.
D1 - D4 are any Ultrafast at 100v -300v 35 20 amp or above. Ultra fst is the important part. They make spikes and add to the overall system energy.
One thing about the 24 volt load is "IN reality" in would better to put that power into a battery for charging while running a 12 volt load in the middle.
I'll draw it if you don't understand what I am saying.
For the more advanced people if you feel the need to try you can impedance match the serial fet and the windings of the transformer.
If you have anymore please ask. I know I am gone more than I am here but I will try to keep up. Lifes terribly busy right now.
One last thing. Do not use this circuit with batteries that the fluid cannot be veiwed. IE NO gel's or AGMS, Nicad ect. Only good lead acid batteries you pop the top on.
If you come across a rapid boiling situation shut you system down immediately.
Just in case you may want to incorporate a manual switch at some point off the main battery.
I am not responsible for damage or injury occurred while experimenting with this circuit. Build and use at your own risk.

Hi MattOriginally posted by Matthew Jones View Post
Thank you for the information ,you are right I didn't understand what is that mean if you can draw I will greatiful .
About the Fet is it NPN ,or PNP channel .
My transformer is 3000w the one I have it from your big setup for tesla switch
Shall I use 8 wire 40 feets #18AWG or thicker wire is butter .
Dave said that I can get a help from you about the board and how much it will coast .
I will start building this scaler charger as soon as I will get the parts and my setup will be just like Daves one because he is using basic stamp and I have two pieces of that stap so why spending more money on the propeller if you can help us with codes for pulsing .
Thank you again

They are N channel Mosfets. Right now for easy use this is the Fet I would use.
IXFN180N25T IXYS | IXFN180N25T-ND | DigiKey
They work good and are easy to use with the screw down. They hold up well but the price is a little high. You'll probably need at least 1 extra in case anything happens.
But then again you can shop around and find something that will work based on the size.
You also do not need the 3 KVA. If you can find a 500 va or something that will work for experiment.
I added the stuff I was talking about with a 12 volt battery into the drawing. Just go back up and look at it. You might need to refresh your browser.

I have Code for the Stamp all ready to go when you get built.

Great work on making this available!
Here is a link to a product to help turn around printed circuit boards faster.
Make your own Printed Circuit Boards in 8 minutes
The only 8 minute PCB fabrication system for making FAST, inexpensive, quality, high-resolution circuit boards with trace pitch down to .005" using any conventional B&W laser printer or photo-copier! It just doesn't get any better than this!
Many electronic supply stores around the world carry the above kits.
Also, if you are a registered user at DigiKey, they have a great resource called "BOM Manager" (Bill of Materials). You can create a BOM manually or upload your own file. This save a lot of time. Will also price the complete BOM, show status of parts and help with substitute parts as well as easily place an order from it.

You'll have to give me the part number.

I ran this by Matt, so hopefully it is correct. It doesn't include the new stuff he posted on the load side.Last edited by Turion; 07-20-2012, 04:52 PM.Comment
