Timebuzzer Led

glebis/timebuzzer-led

Control timeBuzzer hardware LED via MIDI — set color, effects (pulse, strobe, rainbow, fade), and semantic status signals. Use when the user asks to change the buzzer LED color, signal status through the buzzer, or sync the buzzer with other lighting.

timeBuzzer LED

Control the timeBuzzer hardware LED over MIDI. The device has 3 RGB segments controllable independently or together.

Requirements

timeBuzzer device connected via USB-C
python-rtmidi installed (pip install python-rtmidi)
timeBuzzer app may be running (MIDI port is shared)

Script

Single CLI: scripts/buzzer_led.py

Color commands

python3 ~/.claude/skills/timebuzzer-led/scripts/buzzer_led.py color red
python3 ~/.claude/skills/timebuzzer-led/scripts/buzzer_led.py color --hex "#FF8800"
python3 ~/.claude/skills/timebuzzer-led/scripts/buzzer_led.py rgb 255 100 0
python3 ~/.claude/skills/timebuzzer-led/scripts/buzzer_led.py off

Named colors: red, orange, yellow, green, cyan, blue, purple, magenta, pink, white, warm, off.

Effects

python3 ~/.claude/skills/timebuzzer-led/scripts/buzzer_led.py pulse blue --bpm 30 --seconds 5
python3 ~/.claude/skills/timebuzzer-led/scripts/buzzer_led.py strobe red --count 5 --interval 0.15
python3 ~/.claude/skills/timebuzzer-led/scripts/buzzer_led.py rainbow --seconds 5
python3 ~/.claude/skills/timebuzzer-led/scripts/buzzer_led.py fade warm --seconds 2

Status signals (parallel to `hue` skill)

python3 ~/.claude/skills/timebuzzer-led/scripts/buzzer_led.py signal success
python3 ~/.claude/skills/timebuzzer-led/scripts/buzzer_led.py signal thinking --seconds 5

| signal | color | effect |

|---|---|---|

| success/done | green | solid |

| error | red | strobe |

| warning | orange | pulse |

| thinking | blue | pulse |

| working | cyan | pulse |

| idle | warm | solid |

| attention | magenta | strobe |

| focus | purple | solid |

Per-segment control

python3 ~/.claude/skills/timebuzzer-led/scripts/buzzer_led.py segment 0 255 0 0   # seg 0 red
python3 ~/.claude/skills/timebuzzer-led/scripts/buzzer_led.py segment 1 0 255 0   # seg 1 green
python3 ~/.claude/skills/timebuzzer-led/scripts/buzzer_led.py segment 2 0 0 255   # seg 2 blue

Protocol details

USB MIDI device (vendor 0x16D0, product 0x1170)
Sends/receives MIDI CC on channel 12 (status byte 187/0xBB)
LED output: CC 70-78 for 3 segments x 3 channels (R, G, B)
Values: 0-127 (half of standard 0-255 RGB)
The timeBuzzer app controls LED based on active project color; this script overrides it directly

Syncing with Hue

Use the same signal vocabulary as the hue skill. Example combined command:

python3 ~/.claude/skills/timebuzzer-led/scripts/buzzer_led.py signal success &
python3 ~/.claude/skills/hue/scripts/hue.py signal success --group 1

How to use it

Copy the folder

Take glebis/timebuzzer-led from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.

Install what it needs

The instructions reference pip. Without those the skill loads but fails at the first command.
