    @antonej Solo alcune delle perle... Per lui la "democrazia" russa e quella ucraina pari sono.Ha paragonato Putin a Zelensky, ha detto che il russo era vietato in ucraina, anche se è parlato dalla stragrande parte della popolazione... E via così.

    Driving WS2812Bs With Pure LogicThe WS2812B has become one of the most popular addressable LEDs out there. They’re easy to drive from just about any microcontroller you can think of. But what if you have a microcontroller at all? [Povilas Dumcius] decided to try and drive the LEDs with raw logic only.The project consists of a small board full of old-school ICs that can be used to drive WS2812Bs in a simplistic manner. A 74HC14 Schmitt trigger oscillator provides the necessary beat for this tune, generating an 800 kHz clock to keep everything in time and provide the longer pulse trains that represent logic one to a WS2812B. A phase-shifted AND gate generates the shorter pulses necessary to indicate logic zero. Meanwhile, a binary counter cycles through 24 bits (8 per R, G, and B) to handle color. Pressing each one of the three pushbuttons allows each color channel to be activated or deactivated as desired. It can make the strip red, green, or blue, or combine the channels if you press multiple buttons at once. That’s all the control you get—it would take a bit more logic to enable variable levels of each channel. Certainly within the realms of possibility, though.We’ve featured some other nifty tricks for driving WS2812Bs in unconventional ways, like using DMA hardware or even I2S audio outputs. If you’ve got your own tricks, don’t hesitate to notify the tipsline. Video after the break.youtube.com/embed/Yc67xXr24F4?…hackaday.com/2026/02/26/drivin…
