Today I was bored and I remembered this video I saw awhile back that had a TF2 kill counter using an Arduino. I’ve been playing TF2 a lot recently (since it became free to play, I’ve been doing a lot better in comparison) so I figured it would be cool to implement something like that. I could’ve done it with LEDs or even GLCD screens (actually it might be cool to do something with the LoLShield), but since Cubey’s been sitting on my desk unused for the past few months, I thought I’d put him to use. Cubey gradually turns around as I get more kills, and after a certain point, he starts moving his ears. He turns back around in disappointment when I die, though.
I used Python to read the config.log file located in the tf folder (on mine, it’s “C:\Program Files (x86)\Steam\steamapps\your_username_here\team fortress 2\tf”). It reads the latest lines and looks for “A killed B” or “A suicided” and sends either a + to the Arduino when A kills someone or it sends a 0 when A is killed by someone else or kills themself. The Arduino then reads from the serial port one character at a time and makes the Cubey servos move accordingly.
Python and Arduino code are in this zip file.
