‘Hacking’ the Hue: Control Interface for the API

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):

5 lights and a bunch of scenes

From API to LED: Creating the Crystal

Creating the physical enclosure for the CRYP0MANIA crystal was a project in and of itself. This post is about the crystals physical details.

For a summary of the sculpture overall, read more here. For details on the code and wiring of the crystal, read more here.

From API to LED: Digital Details

Lets call it CRYPT0MANIA – the connected crystal.

This post is about the crystals digital details – because it works – it really works!

Note: For a summary of the sculpture overall, read more here. For details on how the physical enclosure was made, read more here

From API to LED: Prototype Enclosure & Decoration

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.

From API to LED: Physical Specifications

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:

Totally Tubular

I like working with the shotgun microphone during Sound & Video projects. It is useful because it records mostly in one direction, and has a bit of length to it, so you don’t have to get close to the source of the sound. It records mostly these areas:

For me, the shotgun microphone really fun to hold and point in various directions …and served as inspiration for the totally tubular
Shotgun Flashlight!!

From API to LED: Duplex Communication

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.

From API to LED: First Connection

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).
