[Kevin] recently scored a Morse code keyer/sounder unit from the 1920s on eBay. While many hams would love to use an old keyer for CW, [Kevin] took a different route and repurposed it into a wireless web-connected morse code keyer.
[Kevin] mounted an Arduino Yun under the keyer, which listens for user input and provides web connectivity. The Yun connects to [Kevin]’s open-source web API he calls “morsel,” which allows it to send and receive messages with other morsel users. When a message is keyed in, the Yun publishes it to the API. When another keyer queries the API for incoming messages, the Yun downloads the morse sequence and replays it on the sounder.
[Kevin] also added some copper electrodes to the top of his enclosure, which act as capacitive buttons while keeping the keyer’s old-school appearance. The left button replays the most recently received message, and the right button sets the playback speed. Check out the video after the break to hear and see the keyer in action.
Thanks for the tip, [Jarrod].
neat
With a sounder he should be using the American Morse code. I knew an old boy who was a rail road telegrapher ad served in W II he said he knew both the American Morse code used ny the rail road wire device and the international most code used with wireless.
wire service nor wire device doh!
BTW the old rail road man saidethey used Prince Albert tobacco cans to amplify the sounder and chage the tone if two sounders where in operation
Operators would be listening to 2 more sounders all the while selling train tickets, mail, and taking care of customers until such time they were able to stop and write down everything they just heard! What’s even more interesting is with these sounders it’s not a simple dit or dah. There’s the on click and the off click.
If you’re ever at Disney head over to the train station in New Orleans square and you’ll here the opening day message:
little story on it http://www.hiddenmickeys.org/disneyland/secrets/square/morse.html
He’s using the coil as a sounder, but it appears to be capable of being a buzzer — that spring contact on the left should be adjusted to break when the coil pulls the armature in.
“When I your age, we used to have to enter our programs on Morse code keys..then stoke the boilers to keep the CPU running”
My students will love this.
Isn’t a Yun a bit overkill for this? An Uno with a Wifi shield would work just fine.
and that WiFi shield? It’s likely got an ARM in it and most of the same SoC architecture as the AR9331 on a Yun.
Is it possible to set up communication between two devices only?
