| Normally, stroboscopes, which are intended to emit short, intensive light pulses, operate from very high voltages. The present circuit wo...
| The Type 555 chip must be one of the most popular ICs used in electronics. Here it is used as a vco (voltage controlled oscillator). The...
| The frequency of the standard Wien bridge oscilator presented is made variable by maktng one of the arms a mono potentiometer. The bridg...
| A deadlock situation occurs if you try to use two optocouplers to isolate two devices connected on an I²C bus. Everything will be fine wi...
| In this series we look closely at digital electronics, what it is, what it does, how it works, and its promise for the future.
| A current source based on one op amp can not easily be made variable, nor is the current very stable when standard resistors are used. T...
| The principle of the circuit is that on the basis of the current drawn by a mains-operated master equipment another appliance, the slave,...
| Thee starting current of heavy-duty d.c. motors can be 3-8 times as high as the normal operating current, which puts a heavy load on the...
| Current souces ar e used in a variety of applications. They can be designed in a number of ways. One of the simplest is a common resisto...
