Second Stage Joule Thief Circuits

@Gadgetmall,

You might want to look at robotic solar engines. They might have the switching effect you are looking for.

From Solarbotics site:
"...The purpose of a solar engine is to act like a power "savings account" -- a small trickle of incoming energy is saved up until a usable amount is stored. This stored energy is then released in a burst, in order to drive some useful (if only sporadic and incremental) work..."

I've been also trying to find ways to switch high current for the 1500's other than buying a $30K transfer switch and robotics is looking good. A small 3v 45ma solar motor can easily make a servo style wire contact on/off or through magnetic switching. Also look for battery monitoring chips for cell phones, they have a very small draw of power.

MCP100-270DI chip VTrip range 2.55V-2.70V
45ua draw, The reset pin is kept low until voltage threshold is reached.

IST to the rescue ...

AGIN...

lol

look at my picture ......  do do do la la la

30 bucks ...

ist

it needs a supply  pulse to trigger it ..

Another thought . ,To regulate the Shot into the battery we could run it threw a 1volt flashlight bulb to absorb some of the current and also produce some  light rather than use resistor but still the problem of turning off that circuit . If we can nail that one part of that circuit then Controlling the out put controller could be devised later . For now the Big problem is keeping the circuit in self run mode after the Bcap reaches Above unity of the Source . .

@Dreamthinkbuild
thank you for the links . we will read on ! Alex if your in here that is kind of what we are looking for . Lets see  if the Volts are in our range .

This problem is an engineering problem which can be solved by some electronics, no? I think the big focus now is amplyfing this effect. From hours for charging the bcap to a few seconds. Then these can start heating homes. There's no need to hold back or be shy. IST seems to be heading into this direction too.

Ist that is pretty nice, 3v trigger too. Makes my $1.25 solar motor quiver in fear.
