Does anyone know what kind of current a 4.5 volt laser pointer needs to
draw?
It's for a somewhat stupid project. Where I work we have 5 library stools
that are never where you need them and can be difficult to find in the
stacks. I'd like to rig up a laser pointer to point at the ceiling and
power it with some solar cells.
