Joule Thief

[gadgetmall]

Welcome Sohei , dig on in and have at it .

To All crossover experimenters,

ok I make my move here . I light 220 ac bulbs again with a 1.2 volts battery . This circuit is touchy  .I wound  a very small coil around a cable choke 300 turns secondary and 28 turns primary .(inspired by TK) I used a pair of mpsa05's and cap . the diode didn't do anything for me but if i touch it the lights come on . or i touch the load side if the bulb opposite the base side it lights but the diode in that position just killed it  both ways . ,so i biased it with a 33k resistor between
the collector of the primary transistor to the base of the secondary transistor . it starts right up and runs that way fine and bright 220 bulb which is dim on my house current but i think the bias is messing up my cap sustaining ability or maybe it just was not meant to be . still its cool but not working like it was supposed to and that was a lot of experimenting hours . I am giving it a rest . tomorrow i'll take it outside and give it a ground and an antenna and se if it does anything;) Video is uploading on my channel and i am getting some rest.

one more thing , I read somewhere a few days ago some guys are doing high powered ground communication(hams like me) they are transmitting thru the earth with a field  of 20 foot rods in the earth and transmitting crystal clear communications 1000's of miles away to the receivers with there fields of 20 foot rods. even past the fault lines. something to think about .

Gadget:

that sounds a lot like ELF (extremly low frequency) and reminds me of Stubblefield's work.

Thanks Gadget.

Just another update.
0.700v at 10mA lighting a neon bulb.
Circuit completed from the ground to the metal frame from my window using a lead/alum cell that was already running an oscillator.

Hi,

Today I did put my first LSJRCO (LaserSaber Joule Ringer CrossOver) into a plastic box.
I use 4 Nicads (1,2V 700mA) in series to give 4,8 Volt. I have put two solar cells on top
of the box and the sun is charging my batteries up. I have an on/off switch and a power on LED
indicator on the front panel. The 2N3055 is at back of the box and have a small heat sink.
The circuit lights up my 230VAC 3 Watt LED lamp to almost full brightness. I have not measured
the current usage of the circuit yet. Maybe I have to change the 100K to find a better relationship
between the light output and the current usage. The red and black connectors is the output to
my LED lamp.

[EDIT1]  I have measured the current usage: 4,8 Volt @ 0,5 Ampere. So I need to use a little higher
value than the 100K resistor. Will try that next.

[EDIT2] I have changed the resistor to 1M Ohm. At 4,8 Volt the current usage is now 0,09 Ampere.
This gives me approx. 8 hours of  "nice night lamp" between each charge of the batteries.

[EDIT3] I have now a 5M Ohm resistor in the circuit. Now the circuit starts every time I switch on the power
and the current usage is at 0,09 Amp. @ 4,8 Volt.

I have now tested a number of easy to wind 'open' transformers using ferrite rods and none can meet the performance efficiency of my 'E' core transformer. As Groundloop shows, a high value resistor between collector and base of the 2N2222 (or an MPSA06) transistor can help to provide just enough positive bias to trigger the circuit into action. My circuit will start automatically with a 7W LED but not with a 3W LED.

I cannot get the lasersabre diode and magnet mod to work. It stops oscillation on my setup.
