This ten channel touch switch circuit can be used to generate ten individual on/off outputs in response to the touching of ten respective touch pads. Touch switches are available in […]

A serious problems came across when examining power supplies is the availability (or nonavailability) of a suitable load. Generally, the issue is sorted out by a lash-up of resistors which, […]

It is very necessary that this electronics enthusiast needs a constant current source. If this type of need does occur, for instance for test requirements, it can be a item […]

You will discover an incredible variety of VW Beetles and Fords on the streets which continue to work on a 6 V battery. In such vehicles (and motorcycles) one can […]

In this post we discuss how to build a simple, regulated fixed +/- 15 V symmetrical dual power supply circuit using standard components and very cheaply. Despite the fact that […]

The variable voltage current power supply might look very small and compact physically, but it has the supply capacity of up to 3 A at 1.25-25 V output voltage. However, […]
