If you’ve got a cheap ham rig, it might not be very practical for you to receive certain transmissions out of the box. However, if you were to hack in a convenient little beat frequency oscillator ...

The 555 timer IC has been around now for quite some time and the list of potential uses for this device appears to be endless. This article contains a few examples of circuits that you might ...

In this article you will learn how to build an optical theremin using a 555 Timer IC. You will learn the functions of the pins on the 555 chip that are used in this build. You will learn that when the ...

IC timers are programmable semiconductor circuits that generate or set timing for electronic circuits. These chips function as single or multi-function units. An IC timer works by charging and ...

It’s technically true that any piece of software can be reproduced in hardware, although modern software’s size and complexity generally makes this a non-starter. But if we go far enough back in time, ...
