@ Mark,
Would you please give the number of turns and the base resistor amounts.
These kinds of things really help with the replications. It saves time for everybody and we can step forward from where you take us, then we can tell you the details, them you can step forward etc.
I think this is a kind of nice model for us to practice on our new planet. (IMO)
Anyway, it will help me a lot.

thank you.

Oh, do you think the angle matters much?

The 45 degree was very clearly stated earlier in agentgates design, I think, but, and when I looked at the pvc connectors, I didn't think they had the right proportions for the 45 degree angle.

BTW, I like the way you explained how to get there. I had a mathematical model, based on 6 divisions not 10. I think this is cool the way you have described it.

A 5'' outer diameter PVC plumbing tube like mine has 64 squares of graphing paper!  Easy to wind 45 degrees and align properly!  Good luck Jeanna

Nice looking coil.

Ok , first i only did this with cardboard tubes so far , in case its a material issue.

Ok , so you connected it like a regular jt , then reversed one wire if it did not work ?

Dose a led work at the transistor ?

Edit , lamp cord lol , you need more turns on the secondary and try i bit smaller wire not covered. to get the wire closer to the primary.

The field around the toroid is not big , that is not how it powers the secondary.

try different size secondary , put more then one at a time .

This a jt , 1.5 , not 9v ... soon

Also try a pot for base resistor (tune it to best performance), also make sure the transistor is good , one of my 2n3904 did not work good either .

Thanks for the info Mark! it will help me!!!

ITS A GREAT PRACTICE MODEL... 

and mk1 ... 


clearly you dont wear your rocks yet ,,

and no disrespect! 

you will too ...  as will every human ! 

i simply share ...  i dont troll  the trolls get pissed when i share ... 

not any more .. 

and adults i spoke to many sir ... 

perhaps parents of the adults

i re read your words mk1 .. and the hostility you burnt in with them !


grow up already!   

your ON LEARN ONLY .. THANK YOU !

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!)
