- description:
- 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-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

VerifiedTrustedCommunity
This skill should be used when designing, running, validating, or auditing statistical experiments on personal or observational time-series data (health metrics, speech/text corpora, behavioral logs, diaries, n-of-1 self-tracking). It enforces pre-registration, exact permutation tests, FDR discipline, data-validation gates, adversarial code review, and cross-validation with external models. Triggers on "design an experiment", "test this hypothesis on my data", "is this correlation real", "audit these findings", "pre-register", "validate this dataset", or any n-of-1 / quantified-self analysis request.
