In this post I will comprehensively explain a simple electric match igniter circuit which can be used for implementing a foolproof ignition of a series of Ematches through a microcontroller based control system. The idea was requested and explained by Mr. Jerry Shallis The details may be understood by reading the following email discussion between […]

Match Transistor Pairs Quickly using this Circuit
In many critical circuit applications, like power amplifiers, inverters, etc it becomes necessary to use matched transistor pairs having identical hFE gain. Not doing this possibly creates unpredictable output results, such as one transistor getting hotter than the other, or asymmetrical output conditions. By: David Corbill To eliminate this, matching transistor pairs with their Vbe […]
