When you develop the prototype of a circuit using capacitors or when you replace an old, defective capacitor with a new one, you often need to know the value of the capacitor you use or replace. At ...

[Mike] sent in a project he’s been working on lately. This little circuit can measure the capacitance of a capacitor by generating a frequency that’s inversely related to the capacitance. He ...

ABB has announced the development of a portable capacitance meter, the CB-2000, that is simpler to use and easier to carry than any other measuring devices previously available. ABB has announced the ...

The inverters in a CMOS CD4069 can be used for both analog as well as digital applications. This Design Idea illustrates this by using all six inverters in a 4069 package to make a closed loop, ...

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 ...
