Laser Card Module - Red
What is a 'laser card' you ask? It is only the coolest thing to hit Spark Fun Electronics since the Color LCD last week! Don't be fooled by the 0.8mW rating. This little module is powered with 3V and projects a very clear, bright, red dot pretty much wherever you point it. If only it had that 'Beware of Laser Radiation' sticker on it...
NEVER aim a laser beam at an aircraft, a vehicle, or towards strangers. In other words, DON'T ANNOY PEOPLE WITH THE LASER BEAM.
