- Take one piece of wood that is approximately 50mm x 100mm x 20mm and set it in front of you.
- Cut out a thin strip of bendable copper about 15mm x 60mm.
- Bend a portion of the copper upward and screw the flat end into the piece of wood.
- Place a screw under the bent end of copper, so that the copper will touch the top of the screw when pressed down.
- Nail 2 pieces of wood together into and L shape.
- Slightly hit a nail into the open side of the wood and wrap the nail will copper wire about 20mm in diameter, using tape to hold it in place, if necessary. (The nail needs to remain 3-4mm below the upright side of the L shape in the wood.)
- Cut out another piece of bendable copper, the same size as used in making the Sender, making sure it ‘hovers’ over the head of the nail.
- Join one end of the coiled wire to the fixed end of the sender and the other end to one of the battery terminals. Connect the other battery terminal to the screw beneath the free end of the sender strip.
This completes the construction of your very own telegraph and you can now start sending Morse Code using the chart we have provided!
