Basically i bought some chickens a while ago and thought about making something to automatically open the door when it gets light cos im pretty lazy in mornings ;) .
After looking on ebay i found out they were between £90 - £110 so i decided to get my thinking cap on and make my own.
I have seen a few floating around but they all seem to be done by time not by light level.
What it must do:
open the door as it gets light
close the door when it gets dark
pretty simple huh? haha
Before we begin i would like it know i am planning on making some of these up and selling them online for about £60-70 if anyone cannot or doesnt have the time to make it themself. i will post it up when thery're on ebay.
so...anyway thats enough chat lets get on with it.
Im also plainning on adding a solar pannel with a diode to charge the batteries when its light but not allow the batteries to discharge through it.
here is the project set up as a trial in my garage :)
