So what u do is you make a redstone torch on a block and then u make a redstone circut powering the block for the torch by the torch. Now wire your reaction to any block broken or placed next to it. I would have put an image but I dunno how to do that.
Well it's just a burn-out torch clock, which responds not only to block updates but also redstone updates and random block ticks. I'm looking forward to 0.14 update to have a real BUD made of pistons.
After messing around, I have decided that redstone is ruined for me, and probably quite a few others. They have made some MAJOR changes, breaking probably around 50% of the tutorials out there. I'll even make a little list.
Pistons aren't instant anymore, also meaning sticky pistons can't let go of blocks.
BUDs are non-existent (The observer is nice, but can't do nearly as many things as a plain BUD)
Redstone cannot be placed next to pistons and other redstone related blocks without connecting to them. (Compacting things gets REALLY messy!)
Even though that list may seem short, it can make redstone much harder for people who have used it for a long time. And since Mojang is eventually abandoning the Java version and moving towards C++ (The language MCPE is made in), these changes will most likely be permanent.
Sticky pistons not being able to leave blocks behind is indeed an intended difference from PC at the moment. But developers are open to feedback regarding this. They said if the community proves that something is strictly impossible to be built without that feature, they will consider adding a feature to solve the problem, which is not necessarily the same as the behavior in PC (sticky pistons suddenly become non-sticky).
PE developers are willing to improve the whole redstone mechanics rather than to port the PC mechanics in status quo. This means existing contraptions designed for PC / Console editions don't always (erm... only rarely) work on PE as-is. We have to accept this and learn how to modify those designs for PE. In fact almost all contraptions can be accommodated to PE. Trust me, I've already successfully done this many, many times.

No, dude, torch will randomly activate from time to time making it impractical. Cool idea though.

Well, pistons are in 0.15.0, but they can't be BUD powered.

At least pistons not being instant is a bug, not an intentional change. This has been confirmed by developers to be a bug. See: [MCPE-15607] Pistons take 3 redstone ticks to extend and 1 tick to retract, which should be 1.5 ticks / 0 ticks respectively
