Circuit HAMCOMM MODEM

The program only needs a simple “infinite gain” circuit to square off the input tones so that they can be read by the serial port. This is achieved using a 741 operational amplifier. The basic circuit of the unit is given below. The RS232 pins are given for a 9-pin serial port. A 25-pin port […]

Make a simple power amplifier – LM 380

This is Make a simple power amplifier – LM 380. Almost all the components are contained in a single 14 pin package and requiring few external components. The supply voltage can be from about 8 volts to not more than 15 volts. The device is supposed to have internal current limiting and be almost indestructable. […]
