I just stumbled upon this project. While I don't really need a keyer for the radio, I'm thinking this project might be a good starting point for a project I have in mind. I'm thinking it might be entertaining to use CW to send status updates to Twitter via CW. I saw another project using an Arduino as well as a Processing script running on a PC to accomplish it. I think they did it that way because the Arduino lacked the horse power and/or memory to handle decoding the CW and sending the status update. I'm thinking maybe the Netduino might perform better in that respect and using the Netduino+, or regular Netduino with an ethernet shield, it might not even need a computer beyond uploading the program and configuring the Twitter login/password.
