it's a public holiday here today. So what better to do than work on this??

So now I have my Joule Thief powered by an old cell phone charger..
That's only 4 volts.. filling 2x 25 volt, 47000 uf caps in parallel.. Running the 100 watt mini inverter, which lights the 220 volt 7 watt LED..
The caps voltage is maintained at 11 volts...

Next step is to try and make it self looping...
