Projects:

  • USB, LEDs, and Some Sensors

    Turning LEDs on and off is fun and all, but why not add a sensor or two that would be useful for something other than the usual light show? Read More...

  • The Versatile Wireless Doorbell

    Advances in technology often decrease price points, but not usefulness. See how to turn one circuit into several devices that most homeowners would find invaluable. Read More...

  • Frequency Counters and Retrofitting

    Even the lowest grade frequency counters are often the most accurate instruments on the test bench. This article will describe their general principle operation, but more specifically on the construction and retrofitting into existing equipment such as the sweep generator and RF signal generator covered in recent issues. Plus, we'll take a look at expanding added features, all the way to a full blown universal counter. Read More...
