Portable Paranoia

The Personal Alarm System was born!

I remember showing it to Dad and trying to summarise what a jumble of wires were inside the switch box.

(The switch box had been a joyous find nestled in the driver’s cab of a bus which had come to rest in a local scrapyard).

He must have winced when he saw the emergency ‘short’ feature – which literally short-circuited everything in case it wouldn’t stop!
