This app is heavily inspired by the Tricorder prop from the Star Trek television series. The prop was a theoretical handheld multiscanner that's been realized in today's sensor-rich smartphones. This app recalls the 90s sci-fi aesthetic as it visualizes data from your phone, global data aggregators (like NASA and the USGS), and the NODE+ bluetooth sensor.
The app features 18 scanner modules that scan for magnetic fields, phone orientation, OS data, local weather, weather and time on Mars, solar X-Rays and particle data, worldwide historical geological data, 3D location data, microphone spectrum data, and several NODE+ raw readouts (including IR thermometer that calculates the current boiling point of 16 elements and compounds by taking local air pressure into account).
For this challenge, two modules were added: Baking Contrast and Munsell Matcher; both utilizing the CHROMA attachment.
BAKING CONTRAST (Supply-chain Management and Color Matching categories) Baking Contrast is a measurement that represents a color's perceptible brightness. Each 0.1 units represent a single shade of brightness as perceived by the human eye. This is used for quality control in the commercial food industry (especially baked goods), where brightness is an indicator of both how the food has been cooked and how it's perceived by consumers. It's used to standardize batches of food and calibrate oven hot/cool spots.
Simply scan a baked good with the NODE+, and the app will give you the Baking Contrast units (BCU). Multiple readings can be taken and are automatically averaged out.
Colorimeters for scanning and reporting Baking Contrast already exist, but they cost ~$4000/ea. This solution would be less than $500 (NODE + mobile app), making enterprise-level quality control available to even small food production businesses.
MUNSELL MATCHER (Color Matching category) The Munsell color system has been around for about 100 years and is used as a standard for roughly communicating colors "in the field." The system describes hue, value, and chroma and was adopted as the official color system for USDA soil analysis in the 1930s. It's also used for mineral analysis, plant chlorophyll levels, and graphic design. The current process of Munsell matching is to visually compare the color of a sample to the reference color chip in an official Munsell color book. These books run from $200 to $3000 for a small, industry-specific cross-section of the Munsell spectrum. This solution gives the user access to all Munsell values for less than $500 (NODE + mobile app), and the NODE measurement is quicker and more precise than the current method of visual comparison and swatch reference.
More robust solutions for both of these application are of course possible (more sophisticated data reporting, organization, export, and analysis), but these serve as a working proof-of-concept for reducing time and cost for existing commercial and scientific tasks.
Bonus: OXIMETER (Visionary category) A NODE+ persistent color scanner module that emitted red and infrared light simultaneously would allow an oximeter to be developed. Scanning a person's temple could give pulse, blood oxygenation, and potentially blood pressure (though BP may require a second scanner). With iOS 8's HealthKit, this data could be stored to the user's account and shared with doctors.
