Designers seeking a quick and easy frequency source often use a relaxation oscillator (Fig. 1) based on digital gates such as the 74HC14 inverter with hysteresis. The oscillator is also useful in ...

With no external components, a 555 can be turned into an oscillator that runs typically in the range of 1 to 2.5mHZ –or who needs a timing capacitor? It is essentially a stripped down version of the ...

[Eric Wasatonic] had a box of SWB2433 transistors that he had very little information about. In order to discover their properties, he fired up his curve tracer to compare these transistors with more ...
