This simple hack save planet :D or maybe your wallet .... - It is just small round piece of board - micro USB for delivery power - 3V regulator - alligator clip holes for your multimeter to measure curent - single board with micro usb is CR2016 =1.6mm + adapter is CR2032 = 3.2mm ... EASY ?????I understand is not like real CR2032 but I believe that help with development battery operated devices.

Enjoy this project?

I know only one chip http://www.analog.com/en/products/power-management/energy-harvesting/ltc3105.html#product-overview

0.5V is very low for everything

  Are you sure? yes | no

You'll need to think beyond Joule thief as it isn't practical for that kind of wattage nor that voltage.

I am working on my project, but don't think it would deliver 4W.  I am guessing 0.5W (or may be a bit higher) might be a realistic number.  I don't have the answer until I try.  0.5V is not an easy voltage to work with as most common parts do not work on that natively.

I agree with Marian (above).  Resistance of coin cells is something integral to several circuits.

Also, the Tindie price is quite high for such a simple board.

I think you just invented a pretty interesting connector in there...

lollipop :D

Now make the output voltage adjustable and add an adjustable series resistance, and this would be really helpful in development.
