buzzkill 0.1.0

Haptic/BLE emergency-stop helper: guaranteed shutdown callbacks.

buzzkill

Guaranteed emergency-stop helper for Python. Wrap critical sections so a user-supplied shutdown callback always runs — on normal exit, on exception, or on SIGINT. Planned roadmap includes BLE device registry and haptic feedback for real hardware kill-switches.

Install

pip install buzzkill

Usage

from buzzkill import EmergencyStop

stopped = []

def cut_power():
    stopped.append("power_cut")

with EmergencyStop(cut_power):
    # work that must never leave hardware/live state dangling
    pass

assert stopped == ["power_cut"]

Roadmap

This is an early 0.1.0 release with active development planned:

• BLE device registry for pairing emergency-stop hardware
• Haptic / status feedback hooks
• Cross-platform signal coverage refinements
