Tutorials/Repeater reboot system

This page is designed as an aid for people who run continuous redstone circuits. These methods work best on small circuits that run in loops, i.e. 4/5 clocks.

The Problem
Currently, there is a glitch involving redstone repeaters. In SSP, when you save and exit, and then come back, any repeaters that were running in a continuous circuit will freeze. A block directly next to the repeater must be "updated" to jump start your circuit. This also appears to happen in SMP if the chunk is unloaded from memory.

This problem has been mostly fixed in SSP in 1.0.0.

Workaround concept
Change at least one block that is adjacent to every repeater that you want to refresh or update Minecraft to 1.0.0.

Method: Automatic reboot using minecart
This method uses a small circular track with a pressure track and powered rails. The rails must always be powered. The pressure track should be next to some redstone going to the side of the repeater. When the cart will hit the rails, it will fire the redstone signal and launch the repeater.

Method: Reboot using lever
Place a lever beside the repeater. You just need to flick the lever every time the circuit freezes, and no matter what position the lever is in it will reboot the circuit.

Method: Reboot using piston
place a piston on the block under a block beside every repeater, hook them all up to a "reboot" button, when you push this the block updates will reset them all at once, it is recommended to muck around with repeaters to get a simultaneous restart of all systems, this is a hand method for advanced computers because it restarts everything at once, and will cause less glitches
