Lunamoth and Julajay work on wireless telegraph

Saturday, August 25th, 2012

Here at Beatty Robotics, we have a keen interest in mixing cool, old technology with exciting new technology. Recently, Lunamoth and Julajay became interested in Morse Code and telegraph equipment. The three of us began exchanging written secret messages in Morse Code. And then the girls continued on by learning to tap the codes with rocks and listen to them at some distance. They are still learning and practicing, but it’s pretty clear that they are getting better and better and will soon be fluent. So now we’ve embarked on our next project, which is to build a functioning telegraph system by refurbishing several very old, antique telegraph keys and sounders, and then combining then with our modern electronics knowledge. We aren’t ready to show the completed project quite yet, but here are some pics of the girls wiring up the electronics. As we complete the project over the next few weeks, we’ll post pictures of the complete telegraph system (we’re hoping it’s going to look pretty cool), an explanation of how it all works, and the list of components.

Lunamoth powers up our wireless Xbee LCD screen to see if test messages are being transmitted properly from the Telegraph key. (The telegraph system itself won’t include an LCD screen. This was just for a test.)
