Mojang added ANOTHER Game Changer...

In this Mumbo Jumbo Minecraft video, we take a look at the brand new togglable redstone block that has been added in Snapshot 23W43A! This new redstone block, the copper bulb is a togglable power source - so we now have one block T-FLIP FLOPS in Minecraft. This Minecraft 1.21 update snapshot also includes 50 new Minecraft blocks, and a new TICK feature!

The Cop Flop is the best name I've ever heard for a redstone machine.

pretty cool how the copper bulb can be used for binary counters and the crafter can be used for base-10 counter

[hjcgaming]

The thing with it being movable by pistons is a really big deal to me. It’s like a redstone block, but without any bud powering, AND you can turn it off. I think its biggest use will be the anti-bud powering power source, which will probably make larger contraptions much more compact.

4:36 lol at the missing observer making it say “SUCSCRIBE” 😂

The binary counter is actually super useful for collecting stacks of items. 7 bulbs will count to 64 before resetting, 6 will be 32, and 5 will be 16. So now instead of perfectly timed clocks or comparator reading, the bulbs can do this with a short chain of redstone.

[donaverboxwood]

My mind immediately went to a Turing machine: copper bulbs in a piston feed tape, which can be swapped between on and off, is exactly like an array of binary digits.

[canolathra]

We can now do proper memory storage in vanilla Minecraft. It's basically a one-block t flip-flop, but being pushable means we can create massive memory banks that can be moved to change what is being read. Imagine a massive hard drive in the form of an 8 bit wide piston feed tape with a bit of circuitry to address it, allowing for any address in memory to be navigated to and the memory state read or written.

[monroerobbins]

Just as a heads up, hope Mumbo reads this: 🚨 the copper bulbs and the crafters have been nerfed heavily, reducing the tick speeds they work at, and all around a false bug report. 🚨 It’s only in the snapshot phase now, so if we make enough noise, we may be able to get things reverted.

This is actually really huge for Redstone. Not just because it's a one-block T-Flipflop, but we have an easier way of storing information now in circuits because of it always staying on until something flips it off, plus it's MOVEABLE information in the circuits.

It's kind of like the skulk vibration storage machine Mumbo did a while back, but you don't have to worry about chunk loading messing it up.

I look forward to what the redstone side of Minecraft cooks up with this block.

[graciewilliams]

I don’t know much redstone, but I do know a good bit about coding and my jaw DROPPED when I saw that this was togglable, I didn’t realize before that there wasn’t a compact way to have that function in Minecraft

[benicho]

This honestly might be one of the most convenient components. Without 1 tick pulses on bedrock edition, t-flip flops are much more annoying because you have to get droppers and stuff involved, but this is just a T-flip flop in a single block. It Could take a bit of the engineering and problem solving aspect of red stone away, but it also could be incredibly handy when you have bigger things to worry about than getting a single t-flip flop to work well in your build.

[insufferableanarchist]

I dont understand how mumbo can just hypnotize me with redstone jargon.

Like, i have a mind thats almost constantly jumping about but as soon as mumbo starts using the funny red pixels my brain turns off completely and all my attention is on him.

[BlazeMakesGames]

yeah what I love about the T-Flip Flop aspect of the block is that not only does it make the concept a lot simpler for more novice builders, but it is also extremely aesthetic. Like the most basic design of putting a button on the block directly means that you also have a built-in indicator of what state the flip flop is in that will probably look pretty nice in most any build that needs it, which I think is really cool

[wimbeedoodle]

Can you combine the copper flopper with an ocean mopper that makes room for a bamboo chopper collected by a hopper feeding into a dropper with a built-in stopper?

Or would that be improper?

[katie-ampersand]

love to see that redstoners are just like mathematicians when it comes to naming things. shoutouts to the hairy ball theorem and the cox-zucker machine

[sashasscribbles]

Another cool thing is we now have a compact T Flipflop design that works on both bedrock and java! Previously I was using a design with locking repeaters which was much bulkier. Long Live the Cop Flop!

Sticky pistons not pulling blocks when powered by a 1 tick pulse is still a really cool feature though, would be nice to see it in Bedrock

[elgordobondiola]

Its important that Mojang doesn't take "hero of the contraption" the wrong way. Having both heroes and background workers of contraptions is important for healthy updates 😊

[MattariOnline]

Just a heads up, someone found that with the Crafter, it's possible to have a base-10 (0 through 9 redstone strength) counter, which can count up or down, and expand to counting to 100, 1000, etc very simply. So it does have a very interesting use in that sense.

[erenender]

As someone who's always struggled with redstone, i'm genuinely so glad we got these because oddly enough they feel easier to understand for me than most old redstone rules

[Kennylotl]

i can't wait for redstone contraptions being even laggier, now that they'll have the bulbs for more lighting updates!
jokes aside, the fact that we now have a single tile t-flip flop (or copper floppers lol) is amazing, i'm genuinely super excited to see how compacted things can get!
