Place an observer block facing the pressure plate. Run redstone dust from the observer into a repeater (4 ticks). Split the line to activate both sticky pistons simultaneously .
Symptom: The piston moves with a loud THWACK, breaking the illusion. Fix: Mimic a "gentle" swap. In Minecraft, use a honey block instead of a slime block on the piston head (honey makes entities slide slowly). In real life, use a pneumatic piston with a flow control valve to slow the extension to 50% speed. Part 6: Advanced Concepts – The Triple-Head Carousel Once you master the dual head swap, why not build a lovely craft piston trap carousel ? lovely craft piston trap head swap
The swap exploits the human brain’s pattern recognition. When a friendly face suddenly becomes a monster, the victim freezes. That freeze frame is all the trap needs to spring a secondary mechanism (like dropping the floor). Even lovely crafts have ugly problems. Here are the top 3 issues with piston head swaps and how to fix them. Place an observer block facing the pressure plate
