1-07-1995 | Although a digital circuit for driving a load such as a lamp or a d.c. motor is fairly simple, it has a few drawbacks. It does not make t...

1-07-1995 | This article proves that building a no-frills RF-signal generator has nothing to do with sorcery as many d.c. oriented constructors seem t...

1-07-1995 | Most proprietary subwoofers require you to be well-off and strong: the first to be able to afford them and the second to be able to lift t...

1-07-1995 | Sometimes you wish you had an electronic magnifying glass to do a really accurate voltage measurement, or watch voltage fluctuations withi...

1-07-1995 | There are frequent occasions in which a circuit needs a low-current supply at a voltage appreciably higher than the 12 V provided by a s...

1-06-1995 | This circuit switches two electrical loads on and off under the control of an acoustic signal. The remote control operates reliably up to...

1-06-1995 | There are often occasions when a higher direct voltage is required than an available battery can provide. In many such cases, the circuit...

1-05-1995 | A circuit is described that, controlled by a computer, generates perfect sine wave signals.

1-03-1995 | The circuit described here mimics the behaviour of a firefly, but only if you build more than one. Although it may be a bit bold to spea...
