As training to make our very own exhibits someday, my class is making dioramas of a daily ritual from our personal lives.
I chose to demonstrate the daily ritual of wireless communication!
The instant an Arduino or Raspberry Pi connects to the web (with a public IP) it is out there for anyone – or anything – to detect.
In our connected devices class, my classmates and I all saw this vulnerability firsthand. After leaving our connected thermostats on for a week, we experienced our devices being scanned and sometimes attacked by machines from across the globe.
The connected thermostat I was building earlier is now complete! 🌡🌡🌡
This thermostat works like a Nest Thermostat (though clearly not as pricey); collecting the current temperature and sending that information to an online server.
A thermostat appliance only needs to send a few bits/bytes of information to get its point across. It can also be used to send sensor information. In this case, a temperature sensor!
I have Phillips Hue at home, so using the nice instructions from ITP Light & Interactivity I was able to connect to my home’s hue setup as a developer. Here is a snapshot of my home’s current setup (collected through a GET request after connected):
I used Node.js and Express to make a local server with some very basic routing features.
The repository for this project and other connected devices projects can be found here. This post is contained to the ‘lilserv’ folder.
Cryptomania is a sculpture designed as commentary on the cryptocurrency pandemonium. It lights up based on the 1 hour price change (a percentage value) of a particular crypto-currency – Ethereum.
Lets call it CRYPT0MANIA – the connected crystal.
This post is about the crystals digital details – because it works – it really works!
Meet our new friend, WeMos D1, aka WeMo, aka WeBro
WeMos is going to use its wifi chip to gather information from the web, and eventually – hopefully – interpret that information and do something about it; namely lighting up some LEDs!
