A simple PHP interface was hacked together to turn the beacon on +and off. The entire thing was just permanently set as an every 5-minute +cronjob. + +Pi-Star has some sort of GPS stuff built-in to it; but I couldn't figure out +how to make it work. It's also been a few years since I tried to even run it in +it's current state. I plan on making use of it soon; so it will likely see re- +writes. In fact the method of scraping has changed entirely. + +I also lost the php that handled the activation. + +Some of this has been resurrected as a hotspot information display. I will +update this spot when I get it's repository up.
