Back scratcher CW key

by OH6DC

(Inspiration to this project came from W7YKN. A video of his back scratcher CW key can be seen in this Youtube link.)



If you are itching to send Morse code, or starting to learn CW from scratch, you might like to build yourself this kind of a telegraph key.




It is basically an ordinary back scratcher but I added a keying feature. A piece of veroboard was sawed like this. There are two new "fingers" to scratch with.




You can see a small gap between the solder in the center and the wire connected to the bending "fingers". (Click the picture to enlarge.) When they bend a keying contact is made.


Now if you excuse me I turn my back to you and show how the key is operated:
