Controlling a quadcopter with hand gestures Typical uses of augmented reality devices involve inserting and manipulating digital content in the physical world. I wanted to go one step further and use an augmented reality device to manipulate a physical object. A quadcopter seemed like a natural choice, given my interest in the FPV hobby. This project uses two devices: a Microsoft HoloLens, and a Crazyflie 2.0 Nano Quadcopter. The Jumper Wire

Is it time for open processors? The disclosure of the Meltdown and Spectre vulnerabilities has brought a new level of attention to the security bugs that can lurk at the hardware level. Massive amounts of work have gone into improving the (still poor) security of our software, but all of that is in vain if the hardware gives away the game. The CPUs that we run in our systems are highly proprietary and have been shown to contain unpleasant surprises (the Intel management engine, for example). LWN.net

TOMU: A microcontroller for your USB port Looking for a ultra tiny development board? Tomu is an ARM Cortex M0+ device that fits inside your USB port. We’ve seen these in person, and they’re tiny. There’s a few commercial devices in this form factor on the market. For example, the Yubikey Nano emulates a keyboard to provide codes for two-factor authentication. The Yubikey’s tiny hardware does this job well, but the closed-source device isn’t something you can modify. Hackaday
