Made another video demonstrating the trigger choke with a strobe. It also shows amp draw and rpm as it is accelerating.

Comparison with and without the choke, as well as adding another choke in series just to show what happens.

SG Core

Guys,

JB recommends the R60 welding rod core for a reason the same as he recommends all the other aspects of a build. The 1/16" rods allow more of them per unit area. You should also allow them to rust naturally outside, do not paint them as has been suggested previously.

Grade 5 ceramics are all you need.

Adjust the base resistance to the absolute lowest value you can get it and then replace it with a fixed resistor. You might find you need to install a switch with a start up resistance and then a running resistance.

Then run the 1 ohm test.

You'll see that the battery charges quite slowly, I believe this is nature taking its course.

Whilst Sep's inductor on the trigger winding phenomenon is interesting I'm not sure it has any practical value.

Regards

Richard

lol thats one good reason to leave it in! Better the bulb than your transistor! What size globe? On my trifilar awg 18 I have a 12 volt 6 watt globe from an automobile shop. It lights up fully under little resistance and 1.5 amp draw. Have never blown it though, but if I do its in a little cradle so its easy to replace.

You should try removing the core of your choke coil and see if it makes a difference. Tesla used a choke coil with a removable core as a simple way to tune some of his devices. My understanding is that changing the amount of metal inside the coil varied the inductional properties of the coil. Might be an interesting experiment.

Hi Ren,

I use two different cores,one is welding rods but not R60 they're about a 1/4" thick, that is the coil on the front of motor with the Radiant dog food can and the coil in back has a magnetite core wrapped with 1" steel pipe.As far as the choke I use an old bifilar SSG coil with #23 awg and #20 awg wire about 400' with strictly magnetite core.I really have to many variables in my setup and tend to try something new in the setup without doing enough testing first.Also, I dont use a light on the trigger coil as it tends to go Pooof when I accidently dont have a load hooked up .

Hey G,

I have tried the coil but it didnt work for me. I was interested to learn that sep has filings for his core, I wonder if the inductional properties of these are such that a choke in the trigger winding is beneficial for him. What do you have for a core? I am using R60. The choke installed with a light bulb only wont run the wheel for me. Maybe I'll try a different choke. The cap can reduce amp draw significantly but I havent found one that increases speed as well. Funnily enough I can run with almost no resistance at all if the cap is in place for about the same amp draw.

Yeah, I used to chat with Nastrand @ overunity regarding pulse motors etc. Good guy, hes been studying at Uni lately so I havent heard much from him. They were some whoppin neos on that motor he had. Break your hands big

Hi Ren,


Have you tried the choke on the Trigger coil yet with the 18 awg wire to cut back on amperage? .Thx for sharing your thoughts .Also is this fella referring to you?.

thanks mrbreau

thanks mrbreau. I'm going to give the 1 ohm test a shot here soon and I've been doing alot of reading on the bedini site you suggested. I found on my original coil that the trigger wire had a short and was causing the oscillation. I got some new 22 awg wire but was running a bit low on 20 awg so I decided to make one of these coils last night since my setup is really small : Winding Coils

The above coil has got QUITE a bit of punch to it when just briefly shorting the individual windings on my battery. My circuit on the other hand needs to be redone now.

Building lots of character right now, but man am I learning a lot!

[ren]

by the way, does anyone else have pets that love the radiant?

My cat cant get enough. He goes to sleep next to the monopole all the time......but only when it is running!

I can say these things from my own findings guys. I have found that the bigger the battery is the more amps are needed on the front end to charge it past the 13v limit. I found my smaller chargers that pushed 25ma-150ma would charge a 7 amp/hour battery in fairly close ration to the front ends decrease but when it hit high 12's it would taper off and end up settling at 12.6 odd, which is still reasonalbly charged. My recent setup uses trifilar awg 18 x 120feet and it can push nearly 2 amps on the front end if tuned so. This isnt necessarily a good thing however.

I charged a 7 amp hour battey in about 2/1/2 hours pushing max current just to see how well it charged. Voltage went up to 14.5 and the test was terminated. After a decent rest period I noted that the battery had only risen from an original 12.35 to 12.62. I concluded that while a battery is under charge measuring its voltage isnt necessarily an accurate way to depict its charging rate. Like JB said, it must charge on natures curve.

I have found that the best charges for my sla batteries so far have been when the input ma was around the c20 of the battery being charged. It takes time for the charge to happen, but the battery ends up holding it much better.

As for multifilars drawing more, well they do. Without changing resistance a single winding will draw approx half that of what two will draw together. I can see just how easily ten quad filar coils draw 10 amps. Infact if that was my build I think Id have trouble keeping it below 12 amps with that many windings being powered. My trifilar (2 power) of awg 18 sits quite comfortably on 500ma, but could indeed draw more.

Anyway just my thoughts.

RE: Aarons point

So each coil had 4 power wires and 1 trigger. So 4 transistors per coil. Wouldn't that be 1 amp per coil but 250ma per winding? The wires I think are twisted, 18 awg and about 100 feet each... so 5 wires about 100 ft each.

Interesting point. I will have to look deeper at this again. And yet another thought, does the more windings you have require more amps?

Good point Aaron...

Well, I was thinking, about that on the video ( Energy From the Vacuum II ) for the large batteries he is using 10 amps. Granted there were 10 coils, so there was an Amp per coil but at 24V. Might we revise this idea to there is a scale of what is low depending on what the size of the batteries are?

Just a thought.

RE: ramain charged.

Hello All

I have some pictures and a response to the replys from my last post.

My goal in using iron fillings and curing in a magnetic field is an
attempt to give my cores a magnetized orientation thus making a good
electromagnet and I don't believe the iron will not remain magnetically
charged

One test for this is to use a compass next to the core after you have been using it for a bit. This will show you if there is residual flux in the core.

RE: low amps = more radiant.

Hi Everyone,

Well I personally think that JB has a good point as far as low amps means more radiant and maybe thats the direction to explore so if anyone could post some low amp success #'s I for one would like to hear from all who want to post and by the way my load tests from last night are looking interesting.thx

I think that answers the replys. And I hope I am right.

Here are links to some pictures.
