Liar, Liar, There's No Fire

The fire alarm module that Technician Dave is holding in his hand was responsible for a visit today by the fire department. Some of the soldered pins on the board had become loose and it's so sensitive that even a small change in conductivity will trigger an alarm.

The binocular looking thing in the foreground allows Dave to see those tiny pins as if they were ping-pong ball size and in 3-D. Cool!
