With 7 tick redstone relay (just repeater set up so that redstone length is on for 7 ticks), I was able to get the set up to not jam up for ~20 dragons.
Well thanks to the help of WurgerSD, i managed to build a nice dragon farm. Here is the link to the IMGUR album. Description is in there aswell. Hope you guys like it.
The farm i mentioned in my previous post has now been running 24 hours. Total amount of hearts: 2800+ Amount of eggs used: 2 (because my bees screwed up 1 when they stopped working because the apiary was full of combs and drones.) Technically my bad still, should have auto-emptied the apiary into an ender chest.
Were talking about PO2 where there is no forestry and thaumcraft. We have to use draconic evo dragons and have to find a different way to trap the dragons
