Dr Ronald Stiffler SEC technology

the wifi signal like SEC. I testing it 2 years ago

see attached videos

I found another led array that worked on a Slayer Exciter and should be a good substitute for Dr. Stiffler's Cree led array that he is using

Skywatcher--- I think that there is enough of a interface between the Stiffler Loop and this Slayer Exciter spin off to keep all of it on this thread.   The signal generator / scope testing should have a comparison to see if the same results can be obtained another way and how much power is required to do that.  Driving an led with a certain frequency, a voltage, and with little or NO amperage --  is the question at hand.

erfandl---What you just showed us (driving an led with a WiFi signal) is perhaps another spinoff we should look at again with these new leds.

I agree with the spin-offs.
After all, everyone here is interested in the most light for the buck...literally at dollar stores
The techniques for driving them that have been shown by Dr. Stiffler are crossing over to
other setups, so it's all valid in my opinion.

The WiFi setup needs exploration for harvesting.
The near field evidently works, they were great videos.
Can we tune in to WiFi at such high frequencies at a distance, without specialist equipment ?

I took apart a Lowe's bought 9W 60W equiv LED bulb, made by Utilitech.
It has a MOSFET and spaces for resistors on it.
Am going to try and bypass the circuit bits and see about driving it from the back plate.

with 5.8 GHz wifi the circuit cant running only works on 2.4 GHz wifi. I think if we design an hi efficiency antenna and connecting to diodes, we getting more distance to work. for now with AA119 germanium diode working from 20cm

...
So i tried 80 turns of 30awg. as primary and was not very impressed, at least with the one wire
- av plug results at around 11.6 volt range input.Then i was thinking and decided to weigh each primary air coil.
The 80 turn - 30 awg. weighs 4 grams.
The 40 turn - 24awg. weighs 7 grams.
The 80 turn - 24awg. weighs 15 grams.
The higher mass primary air coil is more efficient, this test and pictures used the 80 turn 24awg. primary coil.
Was able to light 1 of the led bulbs to about the same brightness as the previous test at .55 watts input,
though only using 134 milliwatts at 11.5 milliamps at 11.67 volts.Seems interesting.
peace love light

Hi SkyWatcher,

Some calculations I attempted show that your higher mass primary air coil (80 turns, 24 awg, 15 gram) has about
0.69 Ohm wire resistance while the lower mass coil (80 turn, 30 awg, 4 gram) has about 2.98 Ohm DC resistance.

Because the 11.5 mA collector current flows through the primary coil, the heat loss is 0.0115² * 0.69 = 91.2 mW
in the awg 24 wire and if you substract this from the total 134 mW input, it comes that only 134-91 = 43 mW is
what makes the magnetic field for the primary coil: this sounds very bad (I neglected the loss in the transistor
coming from its collector-emitter saturation voltage).
You can check with the DMM Ohm meter the primary DC resistance, maybe I miscalculated it? 

Thanks,
Gyula
