1-01-2005 | Here’s a recipe to make LEDs produce slow, continuous light effects rather than abrupt changes normally obtained from square-wave drive sign...

1-12-2004 | The circuit presented here (in two versions) uses a light barrier as a position sensor. In the first version (Figure 1), the light barrier c...

1-12-2004 | In the July/August 2004 issue we published a flickering light for use in models that uses a microcontroller to minimise the component count....

1-12-2004 | CMOS circuits are known for their low current consumption. This is particularly important for battery-powered circuits. Unfortunately, oscil...

1-11-2004 | Quartz oscillators are the way to go when you need a precise, stable frequency source but what do you do when an application calls for a non...

1-11-2004 | This month we invite all fans of the ‘kitchen table’ series to build a classic auditory illusion that has had psychologists and neuroscienti...

1-07-2004 | This circuit consists of six square wave oscillators. Square waves are made up of a large number of harmonics. If six square waves with diff...

1-07-2004 | The 32-kHz low-power clock oscillator offers numerous advantages over conventional oscillator circuits based on a CMOS inverter. Such invert...

1-07-2004 | By configuring a comparator and a transistor to control the oscillator in a charge pump circuit, you enable the pump to generate a regulated...

1-07-2004 | Sometimes the need arises for a simple, gated, pulsed alarm. The circuit shown here employs just four components and a piezo sounder and is...
