Morse Code Oscillator

Part of the requirements for the Communication badge is to build a morse code oscillator. This is how we did it.
Create a sprung switch using a clothes peg and a couple of pennies. Celotape can be used to secure the coins and stripped wire contacts. Thanks to Mark (ASL) for this one!
