my buddy has a solvent that will disolve the epoxy that its incased in...ill see what it is if you really need to get into the box's..

MrFixxall- I'll let you know. I need to remember where I put them. The one I think just needs a power supply. Eitherway until I open them up, I won't know. I do know that two of them powered up. I thought they blinked when I cranked them but I forget now that it been so long.
