Hi guys my names Tommy. Just wanted you to check out my single phase tesla cube. she makes her power in bursts.. (sorry about the unsteady hand.)

Hi Tommy,
Thanks for the link but I'm afraid your video doesn't show up and it says "This video has been removed by the user".
Please repost your video so that we can see what it is about :)
I can't find any information on the Tesla Cube, would anyone care to elaborate?
Thanks.
Wrong link...

Btw Always buy a DMM with an overload block on her... ive fried 5 of the yellow DMMs already. walmarts getting sick of my returns.
ive also used diffrent brands. but the yellow DMM will show u the volts / amps for up to1900 / 19 ( ive peaked up to many times over 30 kw)
better multimeters have a block so ya cant fry ummm.. bastards lol :-P
There would be no info that you could find on it :-) till now.. any questions ask away.
A small Break down.
She pulls in 200 watts 1.7amps and can out put peaks of 1900 volts / 19 amps thats the highest this meter will go and i have fried a few out...
thats a peaks of over 32000 watts
running the voltages into capitors and reading it from there now.. a bit more stable.
I Invented the Tesla Cube BTW i just named it after him.
Hi Tommy,
Unfortunately digital multimeters go crazy when used in "sparky" enviroment like your device produces, you cannot really depend on them.
The best would be to find a useful load for your device (for instance a group of incandescent lamps to make up for the some hundred voltages and a few ampers you expect at the output) and operate it for a certain time to see its longer term behaviour.
To measure any output power you ought to use true RMS measuring instruments (you will not find such at Wallmart), unfortunately they are pricey) or try to correctly rectify the output for possible DC measurements.

Is this some sort of homopolar generator you built with multiple windings? I'm a big fan of those ;).

For each, -in and out-, what length of time? Usable results can't be calculated without time or distance. (Watts can but not Watt-Hours) Since your meter does not know time or distance it cannot give you a reasonable indication.
Like Gyula said, a true RMS meter is needed. At the time frames you are dealing with you would need a scope to measure the times.
This problem snags even the best of us sometimes.
Your statement about in and out power is very possible. What is likely happening is the output pulse is much shorter than the input pulse. So almost all of that power is just squeezed into a much shorter time period.
@time_travel01
Guys are right.
You can't say more out just because your meter spikes.
We've all been there and done that. lol
Putting the output into a dioded capacitor that is also connected to a load will tell you the true story. You can then put your meter on the capacitor and put an ammeter on the load.
Try this. Put your meter on one of your batteries and then spark the battery terminals. What do you see.
Your 200watts input is considerable to start with and one would expect that kind of sparking.
Very good idea to wear gloves. lol
@time_travel01,
It looks interesting but what's stopping you from making a simple brush set for your motor rather than using DMM electrodes to connect with?
Stranded copper wire pressed against the rotor at the top will do, and you could mount it on your stator with hot glue. It is easiest to do without making major modifications, and good for short runs.
Though I would somehow secure that top part of the rotor so it does not wobble as much but stays on the axis.
ive made a few of these babys before.. sum alot more stable and small..Ive used many diffrent MM's.... this is just a place im going to post updates. show how shes working( this new one im building 30 kw :-D.. i just saw the upper head lines of tommy reeds pluse motor.. hes got the same thing i do... more or less. alittle more bloatware thats not needed on his but he really does have sum nice toys.... ill keep ya posted
ive used brush's and slip rings b4 and probly will again... that connection rod is only temp. :-)
ive used brush's and slip rings b4 and probly will again... that connection rod is only temp. :-) im going to build small but poweriful tesla coil to give me a wireless connection from the moving stator to my bridge.
ive hooked up an old analog MM to the connection rods of my digital multimeter. when the spikes hit on one the other neddle jumps as far as it can. i also have this current one hooked into capacitors and am reading the voltage out of them.
also.. timing between the connection ports is what makes this work.. its all about the timing ;-P
Please try to get it to run on charged supercapacitors,
then you will see, if it puts out more power than inputted.
Regards,Stefan.
thats an intresrting setup bro ...
that you in the vid ??
ist!
i guess i may have to finish something now ..... ;)
peace !
