Yeah I thought so.. I am going to order some this week to test my mod with thank you for all the help!

But if all pickup coils are identical and all of their loads are identical, then the current will be the same in each pickup coil and the sum of the energy in all the pickup coils will be less than the energy going into the primary coil. I do not know of any simple explanation that will make this easy to understand.

i agree

the faq the sum will be lower is easily understandable tho.
the same is true with only a primary and 1 secondary.
it resume to: lost. nothing is perfect.

multiple coils lower some types of losts depending on how they are done that all.

I did not try a cap on the output. However they are not LED lights they are mini lights. I am going to order some LED Christmas lights.

Thank you!

In still on Post465, reading this I see Jeanna brought up a good point relating to testing circuits.
Where do I put the clip?

My suggestiion is to those of us who make the diagrams is this.
What say we place a marker, call it a TP (Test Point) on special areas of the circuits that one can go and stick a probe or DMM lead to.

If the circuit designer says a certain voltage should appear here, and it dosent, then he/she can go bak and check it further.

ETP being for "stick the earth clip or probe to
TP being for "stick the active probe to"
TP1 = 1st test point
TP2 = 2nd test point
TP3 = 3rd test point

Example Waveforms.
Quite a few of us now have scopes, cros, to help in our research, so waveforms could be addid.

But at this point in time Im still learning TinyCAD, by the addition of a waveform, for a particular section of the circuit, would be of vital help if one needed it.

What say we also put a *Note* area so if someone prints out the circuit, it will also print several blank lines so the person can jot down their observations about that circuit.

Just my 2 cents worth.

Now I gota fix up a mistake I unintensionally made on my 1st circuit I posted.

@all
I have fixed up my 1st attempt of making a circuit which is a copy of MK1 original
Corrected the owner name
Added TP (test points)
Added a Note area with lines
