Hi,

there is ton of data here. Can any one give or point to a simple....build a light how to?
I can read a schematic, but couldn't design one.
I am competent with soldering, drilling, filing, wood, plastic, and inmprovising with standard tools

I am thinking MR16 based, but am open
Design goals:
Cheap, under $50 if possible
Weight/size: get battery pack in water bottle or smaller would be great
Batttery: rechagable in some way
runtime: any thing 2 hours or above is great

thanks
