Minecraft Redstone Fix - Etho's Block Swapper
Channel: AnexesMinecraft
Date: 17/02/2012

I barely did anything to the overall design, just changed like two blocks, the entire thing is all Etho's. According to my understanding of redstone, his original design shouldn't function properly, but he has video proof that says otherwise. However, he had trouble reproducing it. As far as I can tell, the change I made should allow it to function in most cases, unless a mistake is made in wiring up the pistons. A link to the video where he makes the block swapper can be found below, as well as a link to his channel.
