A few years ago, someone figured out you can take an LED, a coin cell battery, and a magnet, tape them together, and throw them on every conceivable metallic surface. This was the creation of LED throwies, and the world was much worse off for its invention.
With the ESP-8266 WiFi module, we have a tiny, tiny device with a WiFi radio, and just enough processing power to do something interesting. What does that mean? WiFi throwies.
[Andreas Reischle] stuffed an ESP-8266 WiFi module and a lithium cell inside a weatherproof controller loaded up with magnets. On its own, these wouldn’t do much, but with the right combination of software, this little magnetic box can serve as an access point, serving up small JavaScript games to anyone who connects.
The software is based on the NodeMCU firmware and features a web server and a DNS server. The utility of a web server is obvious, and the DNS server redirects all traffic to the device’s index.html file, where a menu of small JavaScript games are presented.
It’s much better than polluting the world with LEDs and lithium; this one has Hunt the Wumpus on it.
Thanks [Oliver] for the tip.
