@kooler

i hope you did see my answer posted between your post.

@jeanna

I tested the small coil it reads around 17 volts at the optimum location , the led a clearly brighter going one way but the meter shows the same voltage.

congrats mark .... 

you have a nice coil ..

i have been playing my b cap wich is still chargeing on the 8 legged spider ... 

im up to 1.491vdc in the bat cap  second battery is drained to .5 vdc ..

i will add another tommorow after i recharge them ..

i have also  been running my low voltage  good speed pulse motor ..

runs on an aa ... 

i will make a video and i will add pick up coils with bridge rectifers ..  and a cap or 2

agin good work .. mk1 ..  have YOU SPOKE WITH MAC  by chance ... ? 

lol

I read first page, and realized there were 809 pages.
You could publish it as a book, collective works, and

well, anyway, I'm a bit strapped for time, so I'll just
post a question regarding the 1st post and 1st answer

Quote:
"A small battery (AA, A,C,D cells) can push over 1.0 amps. An LED or transistor often can't handle 1.0 amp. (check the rating on the package) So you can either: reduce voltage or increase resistance to lower your amps and protect your component. Increasing resistance by adding a resistor is easier (and usually more efficient) than reducing voltage. Your resistor value will be determined by your voltage and how many amps you can safely draw using the I=V/R equation. Resistors are in fact lossy components, but the losses are minuscule in low-power operations and required to keep your other components from frying."

Question:
Can't I just get a transistor that will handle 1.0 amp?
Thus dump the risistor?

Thanks Stew!

I cut a piece of toilet roll at the beginning of this, but I don't think that is big enough for this.
I do have poster paper, and a large can, so I think I will do the 10 divisions 45 degree angle thing Mark posted first.

(I NEED to make a bedini so I can recharge some big batteries, but this is so much more fun!)

jeanna

No problem!  It's funny I have been thinking about making some bedini coils to run some tests incorporating JT/Micro TPU looped/bedini.  Not sure yet though.

@Mk1

I feel like there is something i am missing!  After looking at your coils again I see that yours do not seem to come away from the inside wall of the tube???  Kinda like a rodin would on this shaped tube!  Do you start your winds from the inside or the outside and do you phase them out from each other by 180 degrees?
