Nice, I just bought myself 2 Super Capacitors for $18 bucks + P&P

But how long is 2 150F cap's in Series giving a little over 5v going to power a standard Arduino Uno?

Maybe Grumpy can calculate that for us...

I'm wondering where you're going to find enough electrons to charge it up.

PS: Seeing as how you've got two and they only cost $9, are you going to connect one up backwards to mains electricity and film the explosion/crater?
