Single-phase and 3-phase AC squirrel cage induction motors need some type of control circuit to initiate a start or stop function. The two types of ladder control circuits commonly used are the 2-wire ...

When the thermistor temperature is below a set value the voltage at pin 2 of the 555 drops below 1/3 of Vcc. This turns on the triac controlled heater and also starts the timing cycle. If the ...

Because the wiring and the inputs and outputs (I/Os) are the most vulnerable elements in a system, be sure to locate and identify these elements in the problem circuit. Sometimes, the only way to test ...

The circuit has been designed for the purpose of creating a portable unit of preamplifier that would function as standalone control for gutitars. TL062 – a low power JFET dual operational amplifier ...

PWM or Pulse Width Modulation has generally been regarded as too complicated for PC fan speed control compared against using rheostats or linear voltage regulators such as the LM317. I present here a ...
