Circuit - PWM for Motor Speed Control

Sometimes you want to slow down a brush type DC motor. The most efficient way to do this is with a pulse width modulation (PWM) technique. The hobby corner circuit below can operate from about 3 volts to 15 volts. .

Simple DC Motor PWM Speed Control

DescriptionThe 555 is ubiquitous and can be used as simple PWM speed controlCircuit DiagramCircuit Explaination: The 555 Ic is wired as an astable and the frequency is constant and independent of the duty cycle, as the total resistance (R charge + R discharge, notice the diode) is constant and equal to 22Kohm (givin a frequency of about 1Khz, notice the .......

Circuit - 20MHz VCSEL 3mW LASER TEST CIRCUIT - Circuits designed by David A. Johnson, P.E.

This circuit takes advantage of some new vertical cavity surface emitting lasers (VCSEL) that don’t require light output control circuits. The circuit shows how to drive the device from a single high speed CMOS IC. The circuit can easily be modified to transmit signals from kilohertz to about 50MHz.
