Outcome


Overview

One of the most difficult things to simulate with technology, is the caring touch of a fellow human being.  One of the most simple pleasures in life is holding the hand of someone you care about.  We designed a revolutionary device to meet that need.  When one person grasps the prosthetic hand of their device, the other person's device glows to represent the warmth of their distant friends hand.

Process

While we initially began with a complex breakup facilitation device, we quickly realized that the world had enough things in it to aid in burning bridges.  So after some deliberation, we decided to create a virtual hand-hold.  Using the larger temperature sensor and a RGB LED (for its brightness), we were able to construct a simple circuit.

Components:

1 - Photon

1 - RGB LED

1 - DS18B20 (waterproof)

1 - 4.7kΩ resistor

We spent approximately 20+ hours attempting to write successful code for this device.  The objective was simple; obtain the temperature reading, and link it to the brightness of the paired LED.  The execution was a horrifying deluge of compilation errors, idiosyncrasies, and unforeseeable behaviors.  After many rewrites and the assistance of several classmates, we saw success.  The basic code uses the Dallas libraries to derive a temperature, and some inspiration was taken from the structure of class examples.  Ultimately, the code was its own hideous beast of uniquely forsaken origins.

After stuffing the temperature probes into a couple of foam reinforced nitrile gloves, a fully realized device was born.

Unimaginable intimacy awaits you...
