Low-voltage logic-only CERILUME Phase 1 LED controller using an Arduino Nano ESP32 plug-in module, 5V logic level shifting for WS2812/SK6812 data, microphone input header, and labeled test pads. LED power distribution and high-current switching are intentionally out of scope.
ATmega-based SMD controller for ten 12 V LED strip channels, each rated up to 2 A, with one pushbutton selecting and retaining one of ten lighting patterns.
12 V Bluetooth controller board for 24 LED letter outputs using an ESP32, I/O expansion, and low-side output drivers. Draft specification captured from an uploaded reference schematic image; exact schematic recreation needs confirmation of unreadable details.
Through-hole 9V battery-powered 555 timer circuit that blinks a red LED approximately once per second using an on/off switch and hand-solderable components.
Through-hole 9V battery-powered 555 timer circuit that blinks a red LED about once per second through an on/off switch, designed for easy hand soldering.
Unconnected DER-920 65 W offline LED ballast component schematic grouped by input/EMI, PFC boost, isolated flyback, secondary control/dimming, and connectors. Components are intentionally not wired yet.
