Drone Gets Radial Impellers, Still Flies Good
Quadcopter drones are inherently inefficient when compared to fixed wing drones, but the sacrifice to flight time and distance is worthwhile for the maneuverability benefits. However, it is still a good idea to make quadcopters as efficient as possible to maximize time in the air. There isn’t any way
Tim Alex Jacobs' Latest FLIP Fluid Simulator Uses Flip-Dots for a Soothing Sound
Mitxela's Tim Alex Jacobs has showcased another fluid simulation project, this time on a somewhat larger scale than a wearable pendant — and based around a highly-audible flip-dot display. "For the last few years I've been building all kinds of fluid simulations," Jacobs explains by
Run 15+ Retro Consoles on a $10 ESP32
It is easy enough to turn a Raspberry Pi or an old PC into a retro gaming machine that can emulate a dozen or more vintage consoles. But Fernando Garcia's latest project manages to do something similar using just a $10 ESP32 development board. With a custom bootloader
A Tiny Microcontroller Build Revives Forgotten Computing History
Long before digital computers became the obvious choice for tackling difficult mathematical problems, researchers built dedicated hardware that could outperform them. These specialized machines weren't programmable in the modern sense. Instead, they were designed to solve a narrow class of number theory problems as quickly as possible. KB
