Description: The SpikenzieLabs Telegraph Decoder Kit, is a two part kit that makes an Arduino based Morse Code decoder with a large 16 segment LED display to show the decoder letters and numbers. The kit also includes an elegant telegraph key made out of laser cut acrylic but with "antique" styling.

The electronics is easy to solder through-hole parts. Assembling the key is also part of the fun.

Amateur radio operators know all about morse code. Now everyone can experience the language that started long distance communications.

Tap out international morse code, and see the letter appear. Connect two units together, and have the original messaging system that started it all. In replay mode, you can key in a word, and have it playback. Hack in your own modifications using the Arduino IDE.

Put away that smartphone, it's time to communicate "old school"!
