1.07.1979 | Although not a precision instrument, this transistor tester should none-theless prove a useful aid for checking the quality of `job lots`...

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...

1.07.1979 | Blechschaden-Alarm (Auto Rüttelkontakt)

1.07.1979 | Cold weather is one of the banes of a motorist`s life. Not only must he worry about the car starting on cold winter mornings, but there is t...

1.07.1979 | The circuit described here is based on an unusual method of deterring a possible car thief. Shortly after it is started, an engine fault is...
