DIY laser long-distance listening device

Aug 23rd 2007 3:26AM This device wont work as effectively on double pained glass for two reasons.

First-the glass is thicker with and there is an air buffer zone in between the two panes.

Second- the laser will have two reflections, one off of the outside pane and the other off of the inside pane. so setting up the photo cell would be difficult.
