I appreciate this thing - going to make one or two for the home real soon!
I was wondering however if you had the instructions on how you extracted the leds and circuit board from the flashlights and where I might solder the power leads to it? I am comfortable doing anything in the shop and have almost any tool at my dispose so just a hint or two would help.
Plan on taking this idea and using a version of it to light my DIY printing cabinet too! Good on you for an awesome way to re-purpose these little flashlights into something better!
