Copper Pressure Plates

[hollow walrus]

Had an interesting idea for Copper Pressure Plates. Instead of sending out a pulse while stood on, they send out a pulse when stepped off of.

Can be used for simple landmines as seen in the video below, but I'm interested to hear from others (specifically those who use Redstone) on what else this mechanic may be used for. Let me know what you think!

Compact pressure plate + redstone torch?

[hollow walrus]

can you elaborate?

[vocal stirrup]

It looks like you created a pressure plate that deactivates a redstone torch, compacting it into one block

[hollow walrus]

Yeah it would deactivate a redstone torch for a moment, as long as the setup is correct

[surreal frost]

I don't see that. It would be always on if that were the case.

It seems like a replacement for a not gate and a pulse setter (? Shortener and extender).

Which I imagine would be quite big if it weren't for this

[surreal frost]

It would depend on the implementation of getting on while it's activated though.

@hollow walrus if you needed/wanted a waxed variation, the unwaxed could cut the pulse short when stepped on while it's already on, and the waxed would not cut the pulse short.

I think it's a cool component

this is a falling-edge monostable circuit; if you search the internet for “falling-edge monostable circuit minecraft” then you’ll find a bunch of uses for this

also i think there should be a sound for when you step onto the pressure plate

[surreal frost]

There we go, that's the jargon I was looking for

[high ledge]

the jargon is always fun

why is the edge falling and why is it one stable (mono = one) and not two or three

[frank arch]

• rising edge means the signal goes from low to high (you step ONTO the pressure plate)
• falling edge means the signal goes from high to low (you step OFF of the pressure plate)
• monostable means the system has only one stable state (off)

compare a bistable circuit like a redstone torch; it has two stable states.

[rancid flicker]

no because one needs input and the other doesnt (off requires input)

a bistable circuit would be a lever

[hollow walrus]

hmm so i just simplified redstone a bit- a classic mistake. if you created a falling edge monostable circuit with a pressure plate input, it would be the exact same mechanic just take up more space?

also i do agree it would need a sound for stepping on, i was thinking that during testing lol

[surreal frost]

Yes, but a decent amount of space. Remember, the copper bulb was just a t flip-flop in one block, but redstoners loved it

[frank arch]

that’s not quite right i don’t think

it is maybe something that gets lost in translation between electrical engineering and redstone, but i think something like a d flip flop would still be considered bistable even though it requires constant power to give a high output. with redstone it gets messy because there’s no distinction between power input and signal input except in very special cases

[frank arch]

redstone is turing-complete, so any component you implement is going to be a simplified version of something that can already be done with redstone
