its not too complicated or anything lol, i may have to scratch the host, im just messing around till i find a cheap different sort of host for it... really just messing around but basically i was curious if anyone knew of any good batteries to put in this thing.... that would fit, i can figure out how to hook them up and all if you know the batteries that will put out enough voltage for the blu ray with a fix 100ma rkcstr driver and fit in this, and just incase your curious, that is the tube off of a 100 blank cd spindle lol
