Making a linear voltage regulator using 78XX integrated circuit series is very easy, it needs only one or two additional components to make the integrated circuit chip works. The problem arises when we need a custom voltage specs for the output, since they come in discrete fixed voltage variation (specified by XX parameter printed in the body of the IC […]

Introduction to Current Sensing Current sensing is sometimes needed in a circuit to measure the amount of electric current flow. In signal communication for example, current sensing circuit is needed to read the measurement of remote sensor via current loop. Other common application is in the power supply circuit, when we need to limit the maximum current drawn by the […]

Figure 1. Assembled Hamuro Programmable 1-30V Laboratory Power Supply Laboratory Power Supply Requirement Power supply for electronic circuit experiments need some special features. Ideally we need a precise, stable, reliable, and easy voltage adjustment power supply for working convenience. Being precise means that our power supply should give a voltage as close as possible to the desired value. A stable […]
