This lighthouse is fully remote controlled.
The lamp rotates at 12 rpm allowing a flash of light every 5 seconds.
A 5kg weight is mounted under the island and winched down to the bottom of the dam to anchor the island. The winch is powered by a 6V Ryobi Cordless Screw Driver's gearbox and motor.
The Fog Horn is operated by a 9V motor with a counterbalance causing a vibration inside the tower, amplifying the sound effect of a steam horn.
It's built at 1:35 scale and stands 80cm tall.
What a great addition to your pond!
