1.07.1979 | A frequency range of 0.1 Hz to 999.9 kHz, a choice of CMOS or TTL output levels, and an accuracy/ stability which is limited only by that of...

1.07.1979 | The following simple circuit should prove a useful safety aid to motor-cyclists. In contrast to car drivers, motorcyclists generally only ha...

1.07.1979 | If one wants to measure a voltage which is greater than the range (full-scale deflection) of a meter, there are two things which can be done...

1.07.1979 | The growing awareness of the con-tributory role which stress plays in causing illness has led to increased interest in various forms of `aut...

1.07.1979 | The disadvantage of most wind direction meters is the need for complicated mechanical drive systems which are necessarily prone to wear. The...

1.07.1979 | The basic principle of a current dumping amplifier has been de-scribed previously in Elektor (see Elektors 8 and 21). To recap briefly, the...

1.07.1979 | There seems to be no end to the variety of different sounding door-bel Is which people are prepared to de-sign. Everything from the Hallelu...

1.07.1979 | Mr Frose has submitted an idea which could well revolutionise the viewing habits of the nation. Like many of us, he apparently has regular b...

1.07.1979 | The disadvantage of most wind direction meters is the need for complicated mechanical drive systems which are necessarily prone to wear. The...

1.06.1979 | The E300 and E310 are well-known types of JFET, which have often been used in Elektor projects. Recently however, these two old `workhorses`...
