YUMO GLOBE — Brass Wire Sculpture Digital Clock | ESP32-C3, 7-Segment Display / cyber Desk Gadget

YUMO CLOCK | Hand-Bent Brass Wire Sculpture — ESP32-C3, NTP Time Sync, SK6812 LEDs & Startup Animation Fourth build from YUMO BUILDS. ──────────────────────── Full source code on GitHub — build your own! 💾 SOURCE CODE https://github.com/yumobuilds/YUMO-GLOBE ──────────────────────── This one started as a pile of 1.5mm brass rods and a wooden base — no 3D printing, no CNC, no moulds. Every angle is hand-bent. Inside: an ESP32-C3 Super Mini drives a 4-digit 7-segment display (LTD-4608E) via hardware-multiplexed ISR at 333Hz, keeping the display rock-solid while everything else runs in the background. Five SK6812 addressable LEDs live inside the sculpture — four ring the base, one sits at the top — and they each do their own thing. ──────────────────────── 🔧 PARTS USED -ESP32-C3 Super Mini https://www.amazon.co.uk/dp/B0DDL7WNZX -2-Digit 7-Segment Display https://www.amazon.co.uk/s?k=2-Digit+... -SK6812 Addressable LEDs https://thepihut.com/products/neopixe... -Brass Rods 1.5mm × 300mm https://www.amazon.co.uk/s?k=brass+ro... -DC 3.7V 18650 Li-ion Battery https://www.amazon.co.uk/s?k=18650+3.... -18650 Li-ion Battery charger module https://www.amazon.co.uk/dp/B0DXC1JSB5 -Dome glass stand https://www.amazon.co.uk/dp/B0DWX567HV ──────────────────────── 🚀 FEATURES 🕐 NTP Time Sync — Auto Timezone Connects via WiFiManager captive portal — no hardcoded passwords. Timezone auto-detected via IP geolocation. Syncs every hour with pool.ntp.org and time.google.com. ⚡ Hardware-Multiplexed Display ISR-driven 4-digit mux at 333Hz. Zero flicker. Heavy WiFi + LED tasks run in parallel without touching the display. 🌈 SK6812 LED Animations — 5 Stages Startup: all 5 LEDs sync with the display animation — warm spinner (red → orange → gold), cool fill (teal → cyan → blue), countdown rainbow, neon burst, and a white strobe finale. After sync: the top LED solos — breathing through neon yellow, purple, blue, red, and white. Every 30 seconds: the top LED triple-flashes. Every 5 minutes: base and top LEDs alternate slow breathing in contrasting blue/gold/purple/white pairs. Every hour: full neon show across all 5 LEDs. 🔩 Hand-Bent Brass Wire Sculpture The frame is entirely hand-bent from 1.5mm brass rod — no 3D printing, no laser cutting, no moulds. The wooden base is turned by hand. 📶 WiFiManager Portal No hardcoded credentials. Captive portal on first boot — saved forever after that. ──────────────────────── 📦 LIBRARIES USED FastLED · WiFiManager · ArduinoJson · PlatformIO ──────────────────────── More YUMO BUILDS projects coming soon. 💬 Drop a comment — what should I add next? #ESP32 #ESP32C3 #YumoBuilds #YumoClock #FastLED #SK6812 #NeoPixel #NTPClock #DIYClock #SmartClock #BrassWire #WireSculpture #WireArt #HandmadeTech #Maker #OpenSource #ArduinoProject #ElectronicsProject #DIYGadget #HomeMade
