I found that the Sony app Sound Recorder allows selecting recording directly from these two microphones, and are great for binaural recording, and I gave it a … Read More
“A prototype 3D-printed robotic hand that can be made faster and more cheaply than current alternatives is this year’s UK winner of the James Dyson Award.” (BBC News link) This is a fantastic idea, which has so much value to people without limbs. Bionic prosthetics can cost up to £100,000, and £30,000 for a single hand. The 3D-printed … Read More
This project entitled “Large-Scale, Real-Time, Visual-Inertial Localization” is interesting, using Google’s experimental ‘Tango’ hardware to improve real-time tracking of location and position. The hardware is a tablet computer with a motion tracking camera, a 4 megapixel 2µp pixel camera, integrated depth sensing and a high-performance processor. This equipment aids in tasks like scanning rooms. A … Read More
