CW gun

Want to protect your frequency?
Build yourself a telegraphy handgun and keep those nasty QRM stations away.

Buy a toy cap gun from your kids or from a supermarket. Take some speaker cable and solder one wire to the gun hammer...

... and another wire to the cap roll holder. The holder is electrically part of the trigger mechanism. The hammer is kept in half-way position by rolling the wire around it. Now when the trigger is pressed it touches the hammer unit and makes keying contact.

Keying cable comes out through a hole in the gun handle bottom. Connect it to your transceiver and become a well-equipped band police.

Take a look at this video and learn how to use the key on air:
