Hybrid Drones Could Have Massively Extended Flight Times
https://hackaday.com/2019/07/19/hybrid-drones-could-have-massively-extended-flight-times/
Multirotor drones truly took off with the availability of lithium polymer batteries, brushless motors, and cheap IMUs. Their performance continues to improve, but their flight time remains relatively short due to the limits of battery technology. [Nicolai Valenti] aims to solve the problem by developing a hybrid generator for drones. …read more (https://hackaday.com/2019/07/19/hybrid-drones-could-have-massively-extended-flight-times/)

Farting Baseball; From the Makers of Self-Solving Rubik’s Cube
https://hackaday.com/2019/07/19/farting-baseball-from-the-makers-of-self-solving-rubiks-cube/
Some hackers have a style all their own that is immediately recognizable from one project to the next. For instance, you can tell a [Takashi Kaburagi] by its insides. The behavior of his Farting Baseball project (machine translation) is amusing, but the joke is only skin deep.

Another Take On Harvesting Energy While Walking
https://hackaday.com/2019/07/19/another-take-on-harvesting-energy-while-walking/
Harvesting energy from the human body may sound scary, but fortunately a Matrix-style setup exists only as a cinematic fiction. Instead a typical path lies in external contraptions that use the body’s natural motions to drive a small generator, a bit of flexible piezo material, and so on.

By taking advantage of persistence in human vision, we can use modest bits of hardware to create an illusion of a far larger display.
