2 versions | MCPC 1.11(?) and MCPE 0.15 | by Scrillrock

Hey everyone!

How you know well, I'm Scrillrock and this is the new BUD (Block Update Detector) block in the recent beta of MCPE 0.15 - "The Friendly Update", and the upcoming MCPC 1.10 - 1.11 . It's gonna be a redstone component, that will broadcast redstone signal when a block's position or some other properties, such as a chest being opened I suppose, are changed.

Here's the first official tweet about it :
