This is just me showing off. Bored on evening, I decided to construct a morse code key for my
best friend Girlfriend. I used parts and tooling that I had around my “lab”. Its dead simple and used as a desk ornament though is capable of operation as a J-38 Style Key.
One aluminum slightly rigid stip.
Block of wood.
Two bolts flat head. One nut for the bolts
Hacksaw and drill
Pattern out a piece of wood .25 inch thick or so. put a hole in the aluminum strip. Drill bots into it, in a linear parallel fashion. Mount on board.
See attached photos. Any questions just ask. This was built out of junk in an afternoon so not sure what else I can say about it. For actual use solder leads and a 3.5mm male jack to the bolts for use with something like the 10 dollar 40 meter band kits.
