Fortified Feeder For Feral Felines
https://hackaday.com/2019/10/11/fortified-feeder-for-feral-felines/
Most of the commercially-available pet feeders littering the internet are cheaply-made, with wimpy motors and infuriating interfaces. Want to use it outdoors? Good luck. If you need a heavy-duty, outdoor cat feeder, you gotta heat up your soldering iron and do it yourself.

Fast Video Covers Coax Velocity Factor
https://hackaday.com/2019/10/11/fast-video-covers-coax-velocity-factor/
We once saw an interview test for C programmers that showed a structure with a few integer, floating point, and pointer fields. The question: How big is this structure? The correct answer was either “It depends,” or “sizeof(struct x).” The same could be said of the question “What is the …read more (https://hackaday.com/2019/10/11/fast-video-covers-coax-velocity-factor/)

Flying Batteries for Drones
https://hackaday.com/2019/10/12/flying-batteries-for-drones/
Power is the bane of drone pilots. You’d like to fly longer which means a bigger battery. But a bigger battery will weigh more which leads to less flight time. You have to strike a balance and for most consumer drones that balance is about 20 minutes of flight time, …read more (https://hackaday.com/2019/10/12/flying-batteries-for-drones/)
