[Tito] entered a Self-Charging LED Flasher into the Component Abuse Challenge. It’s a simple re-build of a design by the unstoppable [Burkhard Kainka], and while [Tito] doesn’t explain its workings in ...

Flashing LED mouthguards will be used at the Women’s Rugby World Cup 2025 in the latest development for player welfare. It is the newest advancement in technology for smart mouthguards, which were ...

These days, if you want to flash some LEDs, you’d probably grab a microcontroller. Maybe you’d go a little more old-school, and grab a 555. However, [Jacob] is even more hardcore than that, as ...

Formula One safety devices have come a long way since the sport's inaugural season in 1950. But as cars get faster and more demanding, this equipment likewise must be bleeding-edge to match. Drivers ...

Microcontroller port pins can typically be driven either high or low, or else be put into an "input" or high-impedance state. This circuit uses the three states to drive two separate LEDs with one ...

Chaotic circuits can arise from either computed (using Analog Computers or Digital Computers) solutions to coupled differential equations or from unstable systems/circuits. A new open-source circuit ...

Quantum computing has been making quantum leaps of progress in the last several years — going from theoretical concept to multiple testing environments, to help organizations prep for a time when ...
