1-07-1979 | Generally speaking, resistors with a 5% tolerance are more than adequate for most of the circuits published in Elektor. However from time to...

1-07-1979 | An annoying drawback of many liquid level sensors is the effect of electrolytic reaction between the liquid and the sensors. Metal electro-d...

1-07-1979 | Before setting off for (hopefully) sunnier climes, many prospective holidaymakers use a UV lamp to acquire an initial tan. Unfortunately, th...
