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-rtmidiinstalled (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
