My 1st attempt at an automatic cow slaughter house Works very well though i need to tidy up the building.
Dispensers above the cows spit out wheat (loaded manually so far) and breed the cows, it gets its signal from a 5 min timer from a dispenser and pressure plate (also loaded manually) the timer also acts as a rubbish bin making unwanted items useful.
The baby cows drop into pit 1 then when adult they jump over the wall into pit 2.
Pit 2 is my favourite :) it has water flowing straight into a saw then into a hopper so i can reap the rewards and keep my hands clean lol
The next one is my doggy doo farm, manually loaded with meat from the top using normal dispensers.
There is a detector block in front of the drop down chamber for the dung to drop which sends a pulse to a block dispenser with 3 wool slabs and a redstone torch, so every 4th dung that drops past it'll pulse the dispensers at the top dropping more meat.
I have 6 wolves but pulse new meat every 4 dung just incase either one doesnt produce dung/dung gets stuck/the detector block doesnt pick it up.
Planning on making pig and sheep slaughter houses the same as the cow one as it works very well atm.
