[Johnny Carlo] put another spin on clock displays with his Propeller-based Morse Code clock. He repurposed a tap light, using the tap function as a switch input and actuating the bulb inside with the help of a transistor. If you want to know the time just give it a tap and the device will*transmit*back to you in a series of flashes. This is great if you’re contemplating a career as a Navy Signalman or just need another way to practice Morse Code.
