Under Construction.
Introduction
totemo designed and built this blaze grinder on PvE revision 7 for public use. The design was loosely based on Ethos's Blaze XP Farm, but departed from Etho's design in an attempt to address perceived deficiencies when implemented on a server. Specifically, it was observed that when Etho's design was constructed on revision 6:
- Sometimes, the blocks (pushed by sticky pistons) that concentrate blazes in the centre of the trap would get stuck in the extended position, and
- Redstone repeaters would frequently get stuck in the "on" state. This was apparently due to redstone not updating properly after a server restart. That is, redstone had to be quiescent immediately prior to a restart in order to avoid problems.
Revision A
Revision B
For a time, minecarts were disabled on PvE, following the discovery of a duplication glitch. When they were finally re-enabled, they had been rigged such that the rider always entered the cart upon placing it on the rails. It was no longer possible to use riderless carts as a timing mechanism. Somewhat reluctantly, the timer was redesigned to use a chain of redstone repeaters.
Design Review
Pros
- No sticky pistons used (it was both cheaper (slime is initially very scarce) and more reliable (since blocks can get stuck in the extended position, but non-sticky pistons can't)
- Minimal use of repeaters (but: never saw a stuck repeater, maybe just because it wasn't used enough)
- The redstone circuitry in revision A was very simple.
Cons
- One block width of the spawnable area around the spawner was obstructed - it is 8x8, but the spawning room was 7x7.
- Blazes not in the crushing chamber were not moved 8 blocks away (down) from the spawner. Doing so would have allowed unlimited blazes to accumulate and may have improved the spawning rate. This can probably be remedied in the PvE revision 8 version.
- Crusher timing was not automatic.
