Want a base for your spiffy new Morse Code paddles with a magnetic mount? Try this jeweler’s bench block. It is 13 oz. (375 g), has a shiny surface that magnets stick to, and a grippy silicone base. Plus, it is only $10.99.
The key is a UMPP-Academy made by GM0EUL. It looks like other 3D-printed keys, but it uses the same precision bearings that Begali uses. I have the extra magnets mounted on the sides of mine to increase the force needed to make contact. With the built-in magnets, it was just too touchy for my big, clumsy fingers.
It is plugged into an Ultra PicoKeyer, which is more keyer than I’ll ever need.
