This is a small redstone XP Farm I made. Currently you need to replace the bottles of XP in the chests (Which are below the Chiseled Quartz) if they run out. If you run a Bukkitserver and don't want to reload the dispenser each time the bottles of XP runs out, you can install either DispenserTools by slowbuild or DispenserRefill by LordAkkarin.

Additional Notes

I'm going to add a schematic soon. Also, I plan to add schematics (And world downloads if I haven't done so yet) for all my other builds. A lot of things interfered with my time to build.
