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):
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.
Creating the physical enclosure for the CRYP0MANIA crystal was a project in and of itself. This post is about the crystals physical details.
Lets call it CRYPT0MANIA – the connected crystal.
This post is about the crystals digital details – because it works – it really works!
This week I converted a concept into a partial reality.
The target for the first prototype of the enclosure was to create one half of the enclosure, in order to test different LEDs in am environment that resembles its final form.
As the technical feasibility of the API to LED project comes together, it is time to consider the physical specifications, including design, construction, and materials. Here is the current conceptual design:
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!
Friday night! The perfect time for expanding on the API-to-LED work from last week. The improvement now offers a more diverse set of information and utilizes duplex serial communication.
The result is that now we can now use a toggle-switch to see the 1-hour price change of either Bitcoin or Ethereum in the form of LED lights. The position of the attached toggle switch determines which currency is being shown.
The programming also features a p5 sketch that reflects the information being sent through the serial.
For example, in the video below Ethereum has had a modest positive 1 hour price change (0.06%), so it lights up the green LEDs a teeny bit. At the same time, Bitcoin has had a larger, negative price change (-1.16%), so it lights up the red LEDs quite a bit.
