A Battery-Free Cellphone?

A team from the University of Washington has built a battery-free cellphone that can harness power from radiofrequency (RF) waves sent to it from a nearby base station. The phone not only harnesses the power it needs to operate from those waves, but can also place a voice call by modifying and reflecting the same […]

CCTronics: when Navio+ meets ROS and QT5

Introduction: In robotics and industrial application, data sharing and code reuse are important keys of success. Many efforts have been made by academic researchers to improve Robotic Operating System (ROS) functionalities to extend this middleware beyond its data sharing capability. The result can be appreciated by all the people who have the patience to compile a version and […]

FlyMaple: Low Level Control and Data Acquisition

  Flymaple is a controller board, based on the Maple Project. The FlyMaple embeds a M32F103RET6 (ARM Cortex-M3) as it’s main MCU. It integrates a 3-Axis accelerometer,a 3-Axis gyroscope,a 3-Axis compass and a barometric pressure sensor. By using the 10 dgrees of freedom IMUs and powerful 72MHz high-performation microcontroller, flymaple is powerful enough to handle […]
