BroGlow - AI Agent Status Lamp (Magnetic)

A small traffic light for your coding agents

BroGlow puts your coding-agent status on your desk: green while an agent works, yellow while a session is paused and waits for you, and red when an agent needs an answer or permission.

This download is the 3D-printable magnetic enclosure for a DIY electronics project. The orange mascot attaches to the traffic-light tower with magnets, so it can be removed or swapped.

BroGlow supports Claude Code, Codex, opencode and GitHub Copilot CLI. The lamp uses an ESP32-C3 SuperMini and three 5 mm LEDs. Bluetooth lamp support is available on macOS; USB lamp support is available on macOS and Windows. The lamp is powered over USB.

What to print

• 1 × orange mascot

• 2 × black eyes: the eye STL contains ONE eye, so print it twice

• 1 × black traffic-light tower

• 1 × black rear cover

• 1 × black LED retainer

There are five STL files and six printed pieces. The LED retainer helps prevent the LEDs from being pushed into the enclosure.

Use the supplied print orientation, 100% scale and no supports. Layer height 0.12 mm recommended. PLA and PETG tested, both OK.

Additional hardware

• ESP32-C3 SuperMini

• Three 5 mm LEDs: red, yellow and green

• Resistors: 330 Ω for red, 330 Ω for yellow, 220 Ω for green

• Wiring and a USB-C data cable

• Four axially magnetized Ø3 × 2 mm N52 magnets

• Four DIN 7982 ST2.2 × 6.5 mm countersunk screws: three for the cover, one for the retainer

• Glue for the magnets and eyes

Electronics, magnets and screws are required separately. Disconnect USB while assembling. Check magnet polarity before gluing; the magnet faces should finish flush with their mating surfaces. Follow the assembly guide for the retainer's slide-in installation and wiring clearances.

The cover shows all three LEDs lit for demonstration; normal session status uses one selected color at a time.
