funny you say that forest, xeno said somewhere he suspected the silver secondary was a type of silver litz, i forget the words he used to explain it, but he did say he had some.

My primary is stranded, any ideas what difference it would make.

Hang on i just looked at a close up of the coil in the video and it looks pretty solid core to me so maybe not.

I just read through it. As usual that is some great work Yucca. I'm not sure if my skill level or lack there of will be able to replicate, but I will read, ask questions and hopefully learn something.

Sprtue,

Cheers, I'm pleased you will follow the build.

If you want to replicate then it really is just plug and play, no hardware fab needed except to link the modules together. I will be building on a large vero board using vero strips for the digital and power busses and I will release the source code freely for non profit use. You could perhaps start with single channel first it would give you a nice sin unit by spending $150 over a few months. The piece of kit you will end up with you could sell on ebay for a profit. To buy such a spec sig source from agilent or tektronix etc. would cost megabucks!

p.s. we should talk about this further on the genny thread.

Yucca.

A bit of advice i am planning on getting a 10hz to 2.4GHz freq counter, i would imagine this will be very handy for test on the coil setup.
It comes with a UHF aerial but surely this wont pickup the lower frequencys for measurement, any advice is welcome

http://cgi.ebay.co.uk/YAEGE-FC-1-Portable-Frequency-Counter-10Hz-2-6GHz-VX-8R_W0QQitemZ350192136138QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item518913efca&_trksid=p3286.m63.l1177

Nice bit of kit for the price, Dont take her too close to your rig when its firing. I would try the small rubber duck to start with, in powerful fields it will still pickup LF oscillations and you will have a powerful field. Only if it doesnt work when you get within 1 meter then maybe you could make an external coil on a flylead with a little more length to it.

Some of the RF signals I've seen coming off my quarter wave rig are dual freq and I can see on the scope when I put the probe on the bench about 1 meter away, scope set in mV range. The probe tip is tiny and like a multi GHz antenna so that duck should be swinging nicely even in the kHz when in the proximity of the rig.

I don't know what freq component your meter would display, probably the highest amplitude signal in a dual freq signal. Let us know the performance of it when you get it.

thanks for the advice Yucca.

It will be very handy for the GDO as well

Here goes another 15 day wait LOL

Peter, Yes of course, I hadn't thought of that, your GDO coupled with an accurate freq measurement will give you spot on measurement of any systems frequency response.

It's nice to see whats going on. Thats one thing that frustrates me a little about Tcoil like research, you cant hook your scope up to an active device. Its like you have to keep your eyes shut. A plasma bulb is probably the only instrument to safely hook up. Guess that's why its a bit of a black art, couple with the system and you zap your equipment.

Doh i missed Chapter 5 page 19-20

http://www.free-energy-info.co.uk/Chapter5.pdf

Interestingly it shows L2 as a single coil not 2 separate 20 turn coils.

I do wonder how exact people have tried replicating this build.

Another interesting thing to try would be as follows

I have a microwave transformer tucked under my bench for a rainy day, i am now wondering if i should use 2kv spark gaps to drive the microwave transformer and adjust the feed to L1 until i get 50hz firing on the microwave spark gap.
And load the 240vac primary of the microwave transformer with a mains bulb

Peter, When you try this then maybe also try and match the L1C1 resonance freq to the natural freq of the trafo L2 and then take power off L2 through FWBR.

I've tried just such an experiment with my insectocuter trafo but the potted in caps over L2 are spoiling things and dragging my l2 freq way down.

Have you got a variable cap yet. I'm still on the lookout and want to buy at least a decent air varicap next month capable of going to 2kV. I've also thought of making a varicap using alufoil tape and two CD covers that I can slide over each other, probably it would only be tiny C max though?

@ ALL,

Can anyone provide a current source for high voltage diodes (10KV to 40KV) in small quantities? Preferably in USA.

Hi Yucca
Thanks for the advice, although the microwave transformer will only be about 50hz so i am not sure if i can get the primary down to that, would be interesting to try though.

The Vacuum caps do seem to get snapped up when they are a good price, i have been outbid on a few now, but still looking in from time to time to get 1.

My first task i feel is to trim my secondary to match a quarter of the primary, i guess this is right as the secondary from what Don says is 4 times the length, once i have this i can put my 0.2 on the primary and 0.047 on the secondary and hopefully trim using a variable cap to account for the inaccuracies of the main caps, now if what Don says is true i am willing to bet the resonant freq with the caps should be an even division of the natural frequency, once i have met these conditions, i will feel i would be in a position to say i have a successful replication.

First i should try the neon screwdriver on the secondary while sparking the primary and look for the node and then trim to that point, maybe this is easiest if it works, it's certainly the way Don said to do it.Has anyone tried this method yet.

Peter, I'm watching your progress with great interest, I think you're going to get great efficiency out of the thing!

I haven't tried trimming anything yet other than sniffer coil (taped wire bundles) lengths and turns (hence circumference). I need varicaps or at least a better selection of static caps. Also my rig is only quarter wave, just like a regular T coil, I will need to wind another secondary. At the moment tuning between L1 and L2 is by no means perfect and I think because these aircoils are quite high Q you need to tune fairly accurately. I might build another primary out of bare copper and then make a sliding tap on that, at least I could get good tuning without buying varicap then. But of course the magic wire length ratios would be screwed up.

Yucca.

Not for this project. I do not understand what you are trying to do. I am hoping it will become clear in time. Yucca posted a diagram of coupled loops. But I do not see what that is suppose to accomplish. I have looked at a few Don Smith videos and I find it difficult for me to believe some of the things he says.

I now have a nice high voltage power supply, thanks in part to Yucca, and there are some other experiments I would like to try. But I will be following your build to see what I can learn.
