[Patrick Schless] is thrilled to show off the job he handled about nine months ago. After discovering an antique telegraph sounder he wired it as much as an Arduino to see if he might make it tick. The successful experiment laid the ground work for different hardware that would make it into a morse code email reader.
He doesn’t understand much about the background of the old hardware, however driving it is fairly simple. It’s essentially a magnetic relay so you requirement to have a transistor for changing as well as a flyback diode for protection. when those elements are in location it’s just a matter of toggling a bit. [Patrick] understood he wished to pull messages from an on the internet source, so he set his Arduino aside as well as grabbed a Raspberry Pi. It worked like a charm. His plan was to put this on a bookshelf in perpetuity so he went the additional mile, developing his own PCB as well as having it spun utilizing the OSH Park service. The job is completed with this low-profile laser-cut base which homes all of the electronics.
Now if he wishes to respond to his emails in Morse code he needs to develop this keyboard.
