This is for the Minecraft Bedrock edition (on Xbox One).
The bottom stone block in the picture has a sticky piston underneath it facing towards the block, as per the "circuit breaker" design I linked to above.
If I press the button in the state shown, I would expect to see the section between the t flip-flop and the rising edge detector to turn on steady, and to see the lamp in the bottom left light up for three ticks and then turn back off.
In reality, the rising edge detector doesn't seem to work when it is driven by the output of the flip-flop. The piston goes up, but the repeater after the piston never gets activated.
If I place a lever inline and use that instead of the flip-flop, the rising edge detector works as expected.
I don't see any reason this wouldn't work. What am I missing?
Edit: It seems that if redstone signal passes through a repeater at all, the "circuit breaker" rising-edge detector described above doesn't work. Does this work on the Java Minecraft? Does this have something to do with how blocks are "updated"?
Edit 2: I think I've refined the problem a little bit. If redstone passes directly to the sticky piston, the sticky piston will do a one-tick update on all the blocks around it – meaning the repeater just before the lamp gets activated. If redstone passes through a repeater before reaching the sticky piston, the sticky piston is activated but it does not do a one-tick update to the blocks around it – meaning the repeater never gets activated.
