Detailed Project with Circuit Available Circuit Diagram 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.
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

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.
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.
How To Make a Laser Communicator [Tutorial] Circuit Diagram
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 Credits go to Make Magazine for the ideaLaser communication is generally used to transmit data wirelessly through a laser beam. This demonstration is a more
