Updated Makita torch Hack - VB#8

So I decided to crack open that Makita torch again and bump up the current through that LED to 100mA. (See not-brighter-but-longer)

This was achieved by soldering another 22R resistor in parallel with the one already installed. Quick hook up to a 12V battery confirmed the new current at 114mA, which is good enough.

the only concern I have now is that the LM317 is now dissipating approx. 0.775W (after a full charge) rather than the 0.35W-ish previously, but I'm confident it can manage.

Thanks, and hope to see you soon.
