The radio isn't exactly "my" circuit, it's something I found on the internet, the author's name is on the diagram. I think I'd use a germanium transistor and germanium diodes too.

The voltage collector Lakes linked looks pretty cool, I wonder if I have enough germanium diodes left to try it. I might have enough if I mix 1n34a, 1n60 and NTE109 types, I have a few of each left. I do have a longwire antenna outside, but only 20 meters or so in length, and I do have a good Earth ground. 40 volts at 10 Watts..... hmmm....... we shall see.

Yeah, I noticed the "10w @ 40v" as well, look forward to the video Tk!

@Tinselkicola,

Can't wait to see how good the neutral line antenna will work on this super sized Ambient Power Module!

Another circuit.
https://sites.google.com/site/amplificatoare/free-energy-collector-circuit.

@Tk like the circuit, I remember building something similar many years ago.

Happy 2013 everyone!

There is something with this circuit that looks wrong to me. The electrolytic capacitors (C9, C11, C13 and C15)
at the left side of the circuit seems to be upside down. The + on the electrolytic capacitor should be pointing up.
Also, the 8 electrolytic capacitors (C1 to C8) in the middle of the circuit should be ceramic or non-polariced poly
capacitors. If the polarity of C1 to C6 is correct, why does C7 and C8 have the plus the opposite way?

Attached is how I think this circuit should be made.

@Groundloop,

This schematic of Joe Tate's circuit shows your !00% right about the capacitor and diode direction:

Moderator: The circuit drawing was posted to times. I deleted one of them.

Synchro1,

Thank you for posting the Joe Tate's circuit. I now see that my drawing is probably correct.
I now see that my posted circuit is like the Joe Tate's circuit, but is made of several series
steps to get a higher voltage output. I will solder up a prototype board of this circuit tomorrow
and give it a try.

Alex.

I have designed this circuit in Eagle CAD. Attached is the design files if anybody want to make
a PCB for this. I will solder my first test on a universal printed board first, and if I get some
good result, then I will consider ordering printed circuit boards. A free version of Eagle CAD
can be downloaded from here: http://www.cadsoftusa.com/download-eagle/

Hi Totoalas,

Happy new year 2013. :-)

Well spotted and good work GroundLoop.

Happy 2013!

@Groundloop

The circuit have there looks great. I look forward to seeing what it can do.

In my modified version, C1 and C2 removed, C4 polarity is reversed and cap values are 4700 uf 35 v and all in4007 diodes
I can charge the cap from 0 to 12 v in less than 4 minutes using AC Neutral as antenna and Earth ( from water pipe ) as ground
I can light for a second a 12 v dc 3 watt led lamp , and a 3w ac led lamp will flash slowly
the original tate circuit ( same circuit with c4 reversed polarity and in4148 diodes used ) my meter reading in the 500 v dc scale is 210 and will flash a 3 w ac led lamp slowly (AC neutral RF Charger Load) imtotob YT
will see GL's AMP2

High frequency ambient energy receiver needs high frequency diodes:

For the 50 Hz mains hum, AM radio transmitters and even FM radio transmitters the receiver circuits shown above (the many diodes receiver and the four diodes receiver) will work with "ordinary diodes" like the 1N34 or the 1N4007.

But if one wants to hook into the cell phone towers, WIFI hot spots or WLANs, high frequency diodes are necessary (up to 10 GHz). The one I found is the HSMP-389x series (see the attached data sheet, look at Figures 10 and 11).

Would be nice if someone found other high frequency diodes in the GHz, please specify them here.

Greetings, Conrad

I think I found some here:

http://www.insight-product.com/60_GHZ.html

If you scroll down you can find diodes from 33-140 GHz. Maybe too high for wi-fi and cell?

@Pirate: specially your second quote looks interesting, but I doubt that they sell small quantities.

I also got the HSMS-282x series diodes. The forward Voltage is as low as 0.34V at 1 mA and they should handle a few GHz. (From the data sheet, see page 8: The HSMS‑282x family, with its wide variety of packaging, can be used to make excellent mixers at frequencies up to 6 GHz.)

I will try the diodes I have got and in case of success I will try to find better diodes. The WLANs here are at 2,4 GHz and 5 GHz. In 2014 they want to sell WLANs in the 60 GHz range, but not yet.

Greetings, Conrad
