This project already has several years, it is simple of making and of few and cheap components.

Years ago I wanted to create a community interconnected to internet free of payment.

I had two forms of establishing the communication. One among computers in a wireless way for RF, and to another for laser.

This circuit was tested with 386DX 486DX to two meters, establishing a communication of 19200 bits/s.

IC1              7812
D1               LED 5mm
C1               100uFx25V
R1               1,5M
R2,R3          220 ohm
R4               330
JP1              @ PC Conector 25pin-serial
JP2              @ Laser 5mw
JP3              @ IR 3mm
JP4              @ 12V

JP1                         PC (Serial 25 pins)
