Driving NeoPixel LEDs Using Pure Hardware - No Microcontroller, No Code A recent video by Axiometa explores an unusual electronics challenge: driving addressable NeoPixel LEDs entirely in hardware, without any microcontroller or code. Since WS2812-style LEDs normally rely on tightly timed digital data from MCUs, the project asks whether basic components like counters, timers, and logic gates can replicate the protocol. The goal was to generate the required pulse… |

High Power High Efficiency Buck Converter Circuit using TL494 A buck converter circuit (step-down converter) is a DC-to-DC switching converter that steps down voltage while maintaining a constant power balance. The main feature of a buck converter is efficiency, which means that with a buck converter on board, we can expect extended battery life, reduced heat, smaller size, and improved efficiency. We previously made a few simple Buck… |

RC Phase Shift Oscillator using Op-Amp When an RC phase shift oscillator employs an op-amp in its circuit, it becomes an electronic oscillator with a stable sine wave output. It functions by developing two groups of 180-degree phase shifts, one via the RC network and the other via an op-amp in an inverting circuit. Due to this phase shift arrangement, it produces nearly pure sinusoidal signals with extreme frequency stability and… |
