Heya, I created a 6×7 fully automatic ceiling teleporter that tp's you when you reconnect to the server within roughly 9 seconds.
It only needs one enderpearl to activate. So it get used for both mechanics, the presence detection of the player and the tp itself. U also got a manual trigger, a status lamp and a pearl dispenser for when u get tped.
I can drop the schematic if anyone want it ^.^
