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.
The simple joy of making one single LED light turn on returns this week with the first step towards linking the IRL, moving, ever-changing internet to an Arduino.
Using serial communication and an API call, the green and red lights indicate if the price of Ethereum – a popular cryptocurrency – has gone up or down in the past hour, as per Coin Markets Cap.
What is more, this light shines with different intensity depending on the degree to which the price has changed (i.e. bigger increase = brighter green light).
Do you ever get tired of throwing your own dice during a particularly long game of Monopoly?
Me neither because no one plays monopoly anymore, but for your dice throwing pleasure, here is the Dice Catapult 5000!
You likely have seen the push-to-cross buttons scattered across various crosswalks in NYC.
The functionality and effectiveness of these buttons is often challenged, and with good reason. The primary reason is because most of them are not even connected to the system that governs the traffic lights! As originally reported by the New York Times in 2004:
“…the city deactivated most of the pedestrian buttons long ago with the emergence of computer-controlled traffic signals. More than 2,500 of the 3,250 walk buttons that were in place at the time existed as mechanical placebos.”
