A DIGITAL CAPACITANCE METER
I needed a capacitance meter. However, I couldn’t justify the high cost. So, I decided to build my own.
Over the years, I have amassed quite a selection of air variable capacitors and trimmers. Starting a project that used one of these devices used to feel like it required an Act of Congress to select the right one, since they were of unknown values. I finally decided it was time to add a capacitance meter to my test bench. However, I couldn’t justify the cost ($100+), so I decided to build my own. See if my design will work for you too! |

MAKING WAVES
Examine a number of methods of creating sine waves (and others) from digital values.
Most digital circuits are limited to outputting zeros and ones. While they can do this quickly and efficiently, there are many more types of signals in the real world that require something other than zeros and ones. This article will briefly examine a number of methods of creating sine waves (and other waves) from digital values. |
