i bought this traffic light about 15 years ago from ebay. i never really knew what the plan was but i had this old circa NY decor look going on in this appartment i had. so i figured i needed a traffic light. eventually technology caught up and a Raspberry Pi became available, and i knew i had to do something with it. until recently all it did was blink based on a simple ssh script. now sundays are a blinking party.
i orginally built it a long time ago, and to this day its still a simple monoprice usb wifi adapater, and an orginal raspberry Pi model B. uses an sainsmart 4 channel relay with only 3 in use. at some point i should replace it with more modern equipment and get rid of the plug. but again i built this in 2012 when i first got my hands on a rpi.
i built a simple script in perl that runs an anyevent http web server, and handles switching the relays on and off, its called gpio-web.pl. there is a second script called nfl.pl, it parses the feed and speeds up the parse or slows it down if there are no games, it then triggers the lights based on whats happening in the game.
the code can be found on github
you can set a favorite team at the top of nfl.pl and it should do the rest.
the blinking legend is as follows.
its a fun additional to the house. someday i'll upgrade the power supply, remove the outlet, and put in a propper mounting thing. i need a 3d printer.
