1-07-1979 | Like the previous circuit, this transis-tor tester will indicate whether the current gain of the transistor under test is that of a class `...

1-07-1979 | To many people the radio news bull-etins are of primary interest. This design idea describes a method of switching on a radio by the `pips`...

1-07-1979 | Digital voltmeters are now in wide-spread use and growing ever more popular. Many of the cheaper types of DVM however suffer from a slight...

1-07-1979 | The circuit described here employs a forward-biased diode as temperature sensor. The forward voltage drop of a diode falls by approximately...

1-07-1979 | TAP (read: touch) switches come in all shapes and sizes, mainly as momentary action or simple on/off (latched) switches. Using only a handfu...

1-07-1979 | The sight of so many interesting and diverse circuits contained in one issue may well lead to a quickening of the pulse rate for some of ou...
