Testing the TK Tar Baby

"RED" and "BLACK" is fine with me too.

The colors have been there on my recent diagrams all along.

Yep.

Does she understand the difference between having the BLACK lead connected as shown in the two photos above, and as shown in the circuit diagram that appears above and in the current edition of the "paper"?

After all... it's only a matter of 0.25 Ohm difference... couldn't possibly matter all that much..... RIGHT ?

Meanwhile, back in the DeepBunker, progress continues, showing just one way in which substantial amounts of power can be transferred from a source to a load, using oscillations in the 800-1600 kHz range and properly wired and driven mosfets -- but without any intervening wires... at all.

Among other things.

TK,

When you place the loop/bulb between the xmitter and another loop (like the white coil loop, etc) in a position that causes the "supernova" mode, what effect, if any, does it have on the outside receiving loops range?

@PW: It increases the range a bit; that is, I can slide the outer coil a bit further away before the system drops out of mutual resonance.

The total input power when all three bulbs are lit as bright as I can manage is about 60 W (a bit over 5 amps draw from the battery), dropping down to 10W or so when only the one 5 W rx is used and normal "close" to resonance mode is used. And the bulbs are glowing quite a bit brighter than their ratings, I think... call it maybe 30W total at full brightness, instead of the 20W rated... so the losses are really not that bad, considering.

PW,

Agreed.

Although the lead nomenclature could not be any clearer than FG+ and FG- (as labeled on the diagram) I think we have settled on "Probe" and "Terminal".

.99,

Most of us can live with and understand FG+ and FG-, but to a neophyte, "when the FG+ is minus" is a bit confusing.  As well, FG+/FG- are somewhat misnomers.

Please post your new/modified drawings over here if you would, and if TK doesn't mind.  I am unable to see them "over there".

[TinselKoala]

Of course I don't mind.  Post away...

Meanwhile... lighting up light bulbs to more than full brilliance, wirelessly, is so Old School. It's just a resistive load, anybody can do that.
