Solar Powered Trapdoor Opener For Tree Hut
16 Nov 2014
I've found a use for the broken solar panel I repaired...
Last month I added a trap door and rope ladder to my sons tree hut/platform. Currently it opens with a rope and pulley - which the kids love. But it is a bit tricky keeping the door open and climbing up at the same time. So one of the local kids suggested a motorised trap door. Coooool.
Here's the plan:
So far I've got the solar panel wired up to the power battery box. The next stage is getting the drill fitted with a spindle to wind the rope.
I'll start out using the trigger switch built in to the drill as the control switch. If that all works OK I'll think about a better control panel setup.
