A handheld, high-mass capture node replacing digital snapshots with raw physicality. Features a Zinc-Core chassis, 36V rails for +24dBu headroom, and hardware-vitrified U47/4038 profiles. No menus, no code, just deterministic analog authority for the forensic field witness.

SK-SpeedBit / ESP32_VU_Meter

Star

Three classic audio meters in one firmware project — an analog needle straight out of an 80s hi-fi amplifier, a multi-band spectrum analyzer, and an oscilloscope-style waveform display — all running on a single ESP32 (PSRAM) and an ILI9341 display, at a smooth up to 50-100 FPS thanks to hardware ADC continuous mode and on-the-fly FFT.
