Electronic keyer (keyer) using only 14 components

The scheme we bring you today is very simple even for beginners. To make it, all you have to do is get it and put it together 14 parts. The electronic keyer is very small and it is possible to stick one IC circuit on another, that is, only if you are really interested in squeezing it into the smallest possible space. You can use any voltage for power supply – according to the trial between 3 to 15 volts will be enough.

The creator of this keyer used a 9V battery, consumption is very small and you do not need to turn off the device at all. The flashlight and keyer can be in a nice little box.

As long as you use “lozenge”, electronic keyer will help you create “dots” a “commas”, thus saving your hand and speeding up your telegraphy. The resistor is designed to change the speed. It can be set to a very slow speed, as well as very fast. If you want to tune the antenna, set the resistor to maximum and use a nice long tone to tune.

If someone builds this key fob, let us know your experience. we thank you.
