Optimized for motor control and smart sensing applications, Analog Devices ADuC7128 microcontroller (MCU) integrates a 32-bit ARM7 RISC processor with high-speed, multi-channel data conversion, and 126 kbytes Flash memory. The unit's 12-bit multi-channel, analog-to-digital converter (ADC) operates at speeds to 1 MSPS (mega-samples-per-second). Motor control specific peripherals include six-channel pulse-width modulation (PWM) with H-bridge mode. An on-chip quadrature encoder provides the speed, position, and direction control required by dc motor controls. In addition, the ADuC7128 has an integrated direct digital synthesizer (DDS), and I/V control making it applicable to a variety of motor control applications. Packaged in a 9 × 9 mm 64-LFCSP (lead-frame chip-scale package), the device is specified over an operating temperature range of -40 to +85C.
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.
