laser diode

Laser communication project circuit is a popular basic project that is a useful part of many big projects. The LM386 is a low voltage power amplifier (audio amp chip) IC. This circuit is usful in low voltage customer applications. The inside gain is set to 20, but adding an external resistor and capacitor between pins 1 and 8, will enlarge the gain to any value from 20 to 200. … [Read more...] about Laser Communication Project Circuit Schematic Using Laser Diode and lm386 Low Voltage Audio Amplifier
