Inventor Colin Furze built an elaborate and loud doorbell system for his house, shed, and bunker because he was missing too many package deliveries while he was working. Each doorbell is designed for its environment, meaning they increase in both volume and level of eccentricity, culminating in the bunker bell, which includes an Uzi submachine gun firing into a pipe.
Tired of missing parcels while creating manic machines or chilling in my underground bunker i’ve made the CFDB 500c and it works a treat.
