   I made a tool to communicate data using the PC speaker▲189

   Hi HN, r2t2 is a command-line tool for transmitting data through sound using the PC speaker on the motherboard. The name of the tool is a reference to the R2-D2 robot from Star Wars :) In short, you type some message and it gets FSK modulated and transmitted via sound through the PC speaker. Note that this is the speaker/buzzer that you connect to the motherboard and not the regular speakers that you connect to the sound card. I also made a simple web page that listens to the sound emitted by r2t2 and decodes the received messages. The page can be used by simply opening it on your phone…
