IC Letter Designations A-Advanced S-Schottky L-Low Power B-BiCMOS T-TTL C-CMOS F-Fast H-High Speed 1G-First Generation 2G-Second Generation 3G-Third Generation A-Advanced S-Schottky L-Low […]
Continue ReadingTransistors are active devices (components with the ability to electrically control current flow) that can be used as a switch, an amplifier, or to match impedances.There are three different ways (configurations) to connect bipolar junction transistors. The BJT has three terminal an emitter, a base, and a collector. Of the three possible ways of connecting […]
Continue ReadingThe advantage of the universal transformer circuit is that it allows switching to either 120v or 220v primary operation. The dual secondaries can be configured to use separately, in series or in parallel. In this case the secondaries are setup in parallel to provide an RMS output value of 12.6 volts AC. Find many beautiful […]

Continue ReadingMany times actuators (motors, relays, secondary control circuits, or other miscellaneous loads) require a separate power source than that of the controlling elements.(microcontroller, computer, or primary control circuit) In order to isolate separate power sources or keep output circuits from affecting the input circuits a device called an optical coupler can be used. Optical Coupling […]

This is a simple two transistor AM radio using regenerative feedback to enhance the received radio frequency signal. The variable capacitor (VC1) in parallel with coil (L1) act as a tunable resonant circuit. This “tank” circuit can be tuned to select the desired AM frequency converting it from an electromagnetic wave to an oscillating electric […]

Whether or not you are interested in this topic, it could be critical to your health. Take a look at this Free E-book, it could change […]
Continue ReadingThe Concealment Solenoid Controller uses a Darlington Pair to drive the solenoid latch. The circuit works for everything from door latches to tiny compartment latches. Activation can vary depending on the application. Just a few types of activation devices include: Pin Switches, magnetic reed switches, limit switches, push button switches, or toggle switches. Other possibilities […]
