Ever get to the prepare station on time, discover your platform, after which stare on the board displaying your prepare is 20 minutes late? Bay Space Speedy Transit (BART) could run like clockwork most days, however a heads-up earlier than you permit the home is at all times good. That’s precisely what [filbot] constructed: a real-time arrival show that appears prefer it was stolen from the platform itself.
The mini reproduction nails the official vibe — distinctive crimson textual content glowing inside a sheet-metal-style enclosure. The case is 3D printed, painted, and dressed up with tiny stickers to match the actual deal. For that signature crimson glow, [filbot] selected a 20×4 character OLED. Because the show desires 5 V logic, a tiny level-shifter sits alongside an ESP32-C6 that runs the present. A light-weight middleware API [filbot] wrote simplifies grabbing simply the info he wants from the official BART API and pushes it to the little display screen.
We love how a lot effort went into shrinking a full-size transit signal right into a desk-friendly package deal that solely reveals the information you really care about. When you’re searching for extra of an summary, we’re fairly keen on PCB metro maps as properly.
