Battery power Answered
I have a battery powered laser on top of a spinning disc. This laser runs out of battery fairly quickly, I need to make it last longer somehow. Could I wire the laser to multiple batteries to make it last longer? If i manage to find a mains powered laser then it spinning constantly wouldn't work as it would have a wire.
I ideally need to find a way to power this laser (probably 2 lasers) for most of a day with something that fits on a fairly small spinning disc. Any ideas?
