Splitting the something - a simple experiment that works
Slider2732:
TK and TinMan are having a lively tete a tete in the main thread 'Splitting the Negative' at the moment and I wanted to expand around it all, but not thread hijack !
Hence, because of a re-do of an old experiment outside just now, this is a Bench topic.
Take some stuff outside - a car battery, a couple of clip leads and an LED that's on a blocking oscillator.
(1meg resistor and 0.1uF cap to the Base of something like a 2N3904. 100uF input cap, 120+120 coil on a ferrite core). A Joule Thief basically.
Connect the circuit positive to the battery.
Connect the circuit negative straight into the ground, just stick the cliplead into the earth.
The LED will begin to flash.
The batt positive is something like 12V, the Earth ground is something like 0V.
Fine, potential difference, but where is the conventional circuit ?
Is the Splitting the Negative principle based on the same thing ?
Btw, the battery here is the 'good' Alum one from the solar experiments posted recently. It's at 11.09V, so you don't need a fresh car battery for this experiment by any stretch.

Good day All
Here's a short video: https://www.youtube.com/watch?v=__Idc66i-30&t=15s
This is a follow up video to one I made a couple of years ago which showed *ground_current* lighting up a 100 watt incandescent bulb which was placed in series with the SSTC ground line. https://www.youtube.com/watch?v=wysm0Zxpz5k
It was suggested that a *ground-loop* was being formed through which the current from the H-bridge Inverter could return to the public power grid causing the 100watt incandescent bulb in series with the Ground-Line of the SSTC to light up.
I felt compelled to continue because I wanted to know for certain if a *ground-loop* was indeed responsible for lighting up that 100watt bulb.
In this video the SSTC is powered by a home-made 1000watt battery powered inverter which is running off of a 12VDC deep cycle rechargeable battery. The inverter is running at approximately 21kHz and the output is an AC square wave. The deep cycle battery is NOT connected to Ground (it is Isolated by rubber wheels and located up off the ground in a steel battery box) and neither is the 1000watt inverter. The only ground connection is the 10 meter long ground cable (with incandescent bulb in series) connected from the base of the Tesla Secondary to a piece of Steel Rebar which is part of a concrete footing.
As can be seen, when the SSTC streamer discharges are the longest, the incandescent bulb is at it's brightest.
As in your LED blocking oscillator setup..... the circuit does not complete itself by obvious conventional means (hardwired loop from Neg.>> Pos.). My explanation would involve electrostatic/capacitive coupling from the Tesla secondary topload >> ground....... but we are NOT seeing any ground strikes (ionization pathways to ground) and the Tesla coil is about 2.5 meters above ground and sitting ontop of a plastic table.
So I will leave it to everyone to draw their own conclusions........
take care, peace

TinselKoala:
The battery is acting more like a large capacitor, and you are coupling radiant from the aether right into your LED because of the dielectric plane of the bottom of the battery case being in touch with the ground.
No, really. Haven't you heard that you're not supposed to store a charged LA battery on a concrete floor?

lost_bro,
have you seen this :

you might have hit accidently and temporarily earth resonance

The conventional circuit is the capacitive coupling between the battery plates and ground/ground plane.
