Explore Samsung TV audio amplifier built around TAS5749M by tracing its circuitry and turning a discarded board into reusable audio platform
A Mac script splits any song into 4 frequency bands so the NU40 DK's 4 onboard LEDs flash to the beat. No extra parts needed.
This experiment clearly shows how much the enclosure can influence the sound of even a tiny and inexpensive full-range driver.
Designed for pure music listening experience with a beautifully crafted, responsive, touch-optimized user interface.
Simple Audio Spectrum Analyzer with multiple adjustable display, speed, and sensitivity modes for a customizable audio visualization
Using the LVGL library and SquareLine Studio, I created a visualization that is not only functional, but also enriches any audio system
A Raspberry Pi HAT with a 15-band hardware EQ and browser control β no app, account, or cloud required.
Hardware rejected playback, so I visualized it. A hyper-responsive micro:bit v2 VU meter built on Zephyr RTOS with custom ADC logic.
Class D amplifier with a good performance and better sound quality. We can call it a Class D with Class A specs.
A Raspberry Pi listens at your bird feeder, identifies each call with BirdNET, and shows today's visitors as Audubon plates.
