50W Stereo Audio Power Amplifier based on TPA3116D2
https://www.electronics-lab.com/project/50w-stereo-audio-power-amplifier-based-tpa3116d2/
I designed an audio power amplifier board based around the TPA3116D2. I choose the highest possible oscillator frequency of 1200khz. Many Chinese designs feature no output LC filter which may result in power losses and lower efficiency. Because of that, I choose higher grade components that are included in the output filter. My design also […]

Small, affordable gyroscope for navigating without GPS
https://www.electronics-lab.com/small-affordable-gyroscope-navigating-without-gps/
Researchers at the University of Michigan say they have developed a small, inexpensive, and highly accurate gyroscope that could help drones and autonomous cars stay on track without a GPS signal. The ultra-high-precision MEMS gyroscope – called the birdbath resonator gyroscope – is almost perfectly symmetrical, and made of nearly-pure glass. This, say the researchers, […]
