(http://rbi.ims.ca/4917-54). Although only 10 × 10 × 12 inches, this digitally-controlled subwoofer delivers 2000W of dynamic power with a fraction of the distortion of competitive systems. A digital accelerometer in the unit measures the movement of the subwoofer cone and a DSP controller compares this movement to the input signal at a rate of 15,800 times per second to make corrections and keep the cone's motion as close as possible to the source input. To achieve typical distortion rates well below 0.5 percent, Velodyne Acoustics' engineers chose Texas Instruments' TMS320C2000 controller for its DSP performance and highly integrated MCU-like peripherals.

The DDV-IP is a two-wheeled self-balancing robot that can deliver cold beverages to thirsty folks on hot summer days. A wireless RF remote enables manual control of the device beyond the act of self-balancing. All of the features of the DDV-IP result in an effective delivery vehicle while providing entertainment to the user.
Eric Doster of iFixit talks about the most surprising aspect of the Microsoft Surface Pro 3 teardown. In a presentation at Medical Design & Manufacturing Midwest, iFixit gave the Surface Pro 3 a score of one (out of a possible 10) for repairability.
Barnacles and mussels stay attached to ship hulls and rocks because of a very sticky protein glue they secrete, holding on for a long time even underwater. Researchers at MIT took mussel glue as inspiration -- and as an ingredient -- for engineering their own sticky waterproof adhesive.
