A home made laser in a box made from two seperate ones, held shut with electrical tape (I needed the metal top for a heatsink!). Power source is a remote controlled helicopter battery (7.2V 2700mah).
Yes, or leaves at 30ft on the tops of trees. This really is one strong little lasers. Yours will be a lot neater of course - with a cooling fan as the little 5v 2a supply gets warm :)
