So, please as i said go and check the original video after checking this I'ble out, and I hope it answers some of the questions raised. For those who are interested this I'ble should cover the practical part of the Scout Associations Communicators badge:
Alternative B - Communication codes
Send and receive a short message by Morse code or Semaphore at a rate of five words per minute.
When sending and receiving a message, demonstrate that you know the appropriate procedure.
Know the International Phonetic Alphabet and define at least eight international Q code signals.
Construct a simple Morse code oscillator and send a short message.
I want to make perfectly clear that I got my Idea from www.instructables.com/id/How-To-Make-A-Homemade-Electric-Telegraph!/ this Instructable... It is VERY clever, I made one myself after watching the video, and decided to fill a badge requirement of my Scouts to get them to make one in wood. So please go have a look at the original I'ble as :johnnyrockstah is brilliant... really... just brilliant! Due to me using :johnnyrockstah 's idea I'm not going to explain how i made the battery box (which is also from :johnnyrockstah ) If you want to see how its made please go and have a look at the link.
