Telegraph Decoder Kit

Telegraph Decoder Kit


Make like a spy and dot-dot-dash your way to the secrets of the universe with our telegraph decoder kit.


This kit is a fun, educational way to learn Morse code and soldering. Some say the telegraph is a thing of the past, but Spikenzie Labs dusted off the design and brought it back to the present! This kit blends a nostalgic telegraph style keyer with an Arduino based decoder. As you successfully key in letters they are shown on a 16 segment alpha-numeric LED display. Two LEDs flash indicating 'dots' or 'dashes' and a piezo provides audio feedback for the telegraph. After a pause, the display flashes back the last set of characters received.

Since you can re-program the chip with the Arduino IDE, you can hack it for additional functionality (like hooking it up to a ham tranceiver or sending automated messages.) Another well done, great looking kit by Spikenzie Labs!
