A sunflower’s golden-angle pattern becomes a physical instrument: 89 LEDs, translucent paper cells, an STM32 controller, and a digital microphone combine into a sculpture that pulses with sound. The journey connects procedural geometry, 3D printing, embedded firmware, and real-time audio analysis.
Inside the Portobello Police Station clock tower, a Victorian-style gear train works alongside an early-2000s microcontroller, relays, and switches. This beginner-friendly tour explains how the clock was set, how the chime counts strikes, and why the controller can run a bell without containing a clock.
JetKVM Mini brings browser-based keyboard, video, and mouse control to a matchbox-sized device. With wired and Wi-Fi models, virtual media, open firmware, and optional 4K OS Services, it targets homelabs, remote workstations, and machines that fail before the operating system starts.
Webcams, microphones, monitors, and smart lights are small computers with firmware, update paths, and hidden control interfaces. Agent-assisted reverse engineering shows why signed updates, secure boot, and careful network isolation matter.
Designing with ultra-compact MCUs shifts the engineering focus to power integrity, routing discipline, and event-driven firmware. This guide shows practical strategies for tiny footprints—decoupling, pin multiplexing, sleep/wake architecture, and layout checks.
