Cement battery running a Hartley Oscillator Transmitter.ASF

This shows one of my cement batteries running a Hartley Oscillator AM transmitter. This oscillator circuit operates on extremely low power and can transmit a few feet. The circuit diagram shown here was posted by Kooler at the Overunity.com forum. The transmitter is running on micro amps at about 1 volt.

i played with this circuit along time before i found out it was a hartley ..

and if it wasn't for the 1986 radio shack engineer mini notebook.. basic semiconductor circuits book i wouldn't still know it was a hartley circuit.. cause google images show that even the basic jt is a hartley..??

you do awesome work..

@koolerization ---Thanks. I wish that I has the full set of those Forest Mims electronics books. They still sell them but not at Radio Shack. The ancient oscillator circuits still work just fine. They are are alive and well. People like to change them a little here and there and call them something else ---but they are what they are.

how low can the amps go to?

cool one could use the rebar from the driveway to run the walkway lights.or med steping stones with this tech to run walkway lights plug one into the next .

Hi there,

I was doing some experienting myself last week with those cement batteries and I found that you

can get some more voltage if you use cole instead of kopper.

I bought a sak of burning coles for a barbeque and useds one of the coles and it gave of 1.5 V instead

of 1.2 V.

Maybe you can us it.

Kind regards,

Karel
