Is it possible to make a laser pen cage thing?

Question

Just wondering.... you know those laser cages that are used in films to protect exspensive stuff.... if i rig up a load of laser pens to point directly downwards around an item... (obviously all fixed in to something) and activate them via one switch... is this viable ? google isn't helping me here

Answer 1

If you're looking to burn someone using the lasers a-la Resident Evil, probably not.

But, if you're looking to trip an alarm via these means, it is possible to set up solar-cells that you buy stock, that will send a signal, (or create a break-switch) to set off an alarm/speaker/motor bell/etc. to make a noise or alert you or have some other electric response occur (e.g.: locking a door.)

You'll have to do an amount of disassembly of the laser pens to link them all up to one switch/breaker,  but it shouldn't be too difficult if you know the type of batteries (voltage, current, etc.) that you are using with said pens, so that you won't fry the diodes or circuits.
