That's pretty good -- new technollogy supported by Kickstarter. I didn't realize the site was supporting this type of new technology. It's also interesting to see a that a device that needed $35,000 actually received more than $300,000.

The story says "projects an infrared beam that monitors the radiation emitted from the surface of an object at a distance".

Actually, non-contact infrared temperature sensors simply monitor the black body radiation emitted by all objects to determine their temperature. They do not "project an infrared beam". All objects emit infrared photons, and the sensor picks them up. As the temperature of an object increases, the photons are no longer in the infrared and they become visible. We call this "red hot". If they get really hot, we call them "white hot" because the photons emitted are white in color. The shape of the spectrum emitted follows a charateristic curve, and if you can take measurements at at least two different wavelengths, you can calculate the temperature. There are also thermometers that make measurements of absolute energy at at one wavelength.

Regardless, all of the non-contact thermometers simply monitor photons emitted by objects. They do not project an infrared beam.

From home enthusiasts to workers on the manufacturing floor, everyone's imagination is captured by the potential of 3D printing. Prototyping, spare parts creation, art delivery, human organ creation, and even mass product production are all being targeted as current and potential uses for the technology.
Solar and wind energy are becoming more viable as a source of energy on the electric grid. For decades, the major drawback to solar and wind was that they’re temperamental. A cloudy day kills solar and a still day renders the wind turbines useless. Automation tools, however, are providing a path to help these renewables become practical.
In honor of Earth Day, the National Security Agency has launched the STEM Recycling Challenge in Maryland schools to encourage kids to think about where the garbage they throw out every day actually goes.

Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
