If you are just starting out in electronics, you need tools. But it is hard to build all your tools. Even though we see a lot of soldering station builds, you really ought to have a soldering iron to ...

This Design Idea describes a simple two-chip CMOS circuit that can sort capacitors into 20 bins over a wide range (100pF to 1µF), using 10 LEDs to display the value range. The circuit is power ...

This Design Idea presents a very accurate, yet very inexpensive, capacitance meter. It was specifically designed for measurements of low value capacitance – with an accuracy of better than 1pF – for a ...
