Waits for laser input. 3.Once laser input is received, a "snapshot" of the active lasers is saved to a temporary array. 4.This temporary array is compared to the reference array created in step 1. 5.Once a match is found, the character associated with that input is displayed . 6. This process is repeated until all laser tubes are Fig. 2: Laser Communication system: Receiver circuit. Assemble the transmitter and receiver circuits on separate PCBs and enclose in suitable cabinets. In the transmitter cabinet, fix two terminals for connecting the audio signal. Fix switch S1 on the front panel and the laser diode (LD1 or laser pointer) to the rear side of the cabinet.
You won't be hosting any parties with this system, but you could easily have a private conversation over the system. So that's how you can build a very basic laser-based communication system for under $10. If you want 2-way communication, build a second copy of the system so that each side has both a receiver and transmitter. Let's do something more than make a dot on the wall with a laser: let's build a communication system for less than $10. Safety First: Even before starting this project I want to mention to always be careful with lasers: even a weak laser can cause permanent damage to the human eye in a few seconds. More powerful lasers may cause blindness

For this step, you are going to need the battery from "Step 2: Disassemble the Laser Pointer (a)" and Electrical Tape. Use the tape to adhere the ends of the wire to the battery. MAKE SURE that the positive side of the battery is wired facing the Switch *NOTE* Make sure the POSITIVE side of the battery is wired facing TOWARDS the SWITCH
In this post, I'll show you how to build a simple, inexpensive laser communicator in which you can safely send a wireless data signal over a laser beam. We will build a transmitter and a receiver, and the setup will operate very much like a radio station, except that we will send the signal over a laser beam rather than a radio wave.
