Build Night - Sept 20 & 27, 2011
Laser Beam Spy Communicators
We plan to build a device that allows you to transmit and receive sound over a beam of laser light. This device should also let us hear sounds from inside a house by bouncing the laser light off the window glass back to our receiver. The amplifiers from our Cracker Box Amplifier build will help boost the sounds.
Build Night at the HMS Beagle Science Store.
6:00 to 8:00 p.m. - 180 English Landing Dr. Parkville, MO
