Sometimes, I’ll find something interesting on the internet, or in my email, and open up a tab in my web browser meaning to read the page or watch the video at some later date. Often, those tabs stay open for a week or more. Here are three such tabs that relate to amateur radio….Dan

Telegraph Decoder Kit
MAKE: magazine describes this kits as:
…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 transceiver or sending automated messages.) Another well done, great looking kit by Spikenzie Labs!
It seems a little expensive ($45), but it is Arduino-based, so it is hackable. Might be fun to play around with.
