I have a job.

Sorry for the jump scare, but it's true.

Just this year I had graduated from college with a degree in electrical and computer engineering, and now I'm a software engineer.

But despite this, I've never tried Minecraft Redstone.

Which is weird, right?

Redstone seems pretty similar to like actual engineering, so how hard could it be for someone like myself to actually learn it completely from scratch?

And to make this more fun, I invited my fellow engineering friend and challenged us both to make the 3x3 Redstone Piston door,

which is the most iconic redstone contraption of all time.

But there's a twist.

We were going to do it without any experience, any tutorials, and pretty much no previous knowledge.

Now at first I thought despite this limitation it would be kind of simple.

It's literally only nine blocks.

But in order to actually complete

it we would have to learn some of the most important redstone mechanics in the entire game.

Not that we knew that at the time unfortunately for us.

How was the door this far?

I don't get it.

And since we knew very little about redstone we decided to start at the very beginning.

Clicking on random lights like a caveman.

Oh I did it.

Is it just a lamp?

But after all

that we got to work conveniently enough anthony already knew how to make a clock not

that we really knew how it worked what the there's no

power to it though we then moved on to the 2x2 piston door

which allowed us to understand how piston mechanics worked so then

if i do this maybe does it do both it does okay we also accidentally discovered how

if you don't insert the redstone line directly into the piston it just straight up doesn't work

and then if i do

that what either way it was finally time to start the 3x3 piston door what you came here to watch

and our first step was figuring how we were actually going to power all nine of the blocks of the door.

I mean, we can do the staircase strat probably, right?

Oh, wait, no, but how do you send it to the bottom one?

Because this won't work, right?

What?

Wait, how?

I didn't think this was going to work.

Now, this was really confusing to us,

so we ran a couple of experiments to see maybe if there was a pattern of some sort we had missed.

What?

So as long as you power the top one, all following ones get powered.

But this doesn't work.

Why?

Why does this not work?

What's the rule?

Okay, so this works, this works, that works, but this doesn't work.

So after we somehow managed to power the sides of the door, or at least we thought we had finished it at the time,

it was now time for the hardest part of the door, the freaking middle block.

It's the only one you can't directly attach a piston to,

which means you have to move one of the other blocks away before you can even interact with it.

And since we didn't really know how to do that, our first solution just was to use an observer.

Why an observer?

Good question.

We didn't know either.

In fact, we didn't even know how it worked.

The only thing I understand about observers is they like observe a signal

and send one when it when it does when something updates.

Now, fortunately, I have made sugar cane farms in the past, so I went to him and just built one hoping it helped me understand things

and then just power it oh whoops yeah okay

so it's sending a signal like look whatever updates

it sends a signal ah i don't know wait i don't know how this bottom part works

but i've that i just guess can the obs is the observer powering that maybe

yeah yeah okay so you actually don't need any of this and all you need is this system and it powers it.

In fact, does this work even if you do this?

No. Redstone passes through the block, and then it powers it.

We kind of got distracted at this point, and we proceeded to completely forget about observers for about an hour.

Not that we weren't productive, though.

Instead, we decided to learn about how piston collisions work instead.

Because if you do this and this, and you power this on, it doesn't pull the bottom one.

Okay, see?

So like, even though this is a sticky piston, unless the sticky piston is powered, the stickiness doesn't matter.

This ended up being really useful to us since we can now chain pistons one after the other

and it gave us a potential solution into removing one of the blocks out of the way.

But what wasn't as useful was my embarrassing attempt at trying to understand how slime blocks worked.

I'm pretty sure that these two mo - Okay, I'm just wrong.

What the fuck?

I thought if you have slime, they connect together. Was I just wrong?

Could it be honey?

No, that also doesn't move them together.

I don't get what honey and like slime does.

What's the difference between the two anyways?

Like it doesn't do anything.

So with me not ever realizing I was using slime blocks wrong

and just thinking they were pointless we decided to just not use slime at all whatsoever in our first design

and decided to just try a new method i came up with instead okay

so we're gonna move this then we'll move this right

we have like three inputs basically for us right one of these three from here

you do pull this one then you pull this one then you pull this one and you pull this one again

That's the sequence to pulling one of them.

So then maybe if you chain it like this, and you have a fourth one,

and then you have one at the back that's going to pull this one away.

Then you have to do the orientation again, where you do this, and you do this, and then you do this, and you pull this one,

then you pull this one, then you pull this one and you pull this one

and you pull this one and you pull this one and then it's away.

Now

that we knew how to at least get the middle block out of the way

it was now about figuring out how to power all of those levers using you know actual redstone.

Our first solution involved using a clock but quickly realized that's completely useless

so then we moved on to observers again and despite our previous testing we still didn't really know how they worked.

100

So it was back to experimentation once again event handler

101

or some that's the best way i can describe

102

it why did this update twice this this updated twice oh it's because of the civil line what

103

wait why is that that's not supposed to happen do you need the observers though like

104

because like technically speaking you have like a branching path followed by delays

105

and then this is state two right here do this

106

and then that happens after

107

so then you have sequential logic wait

108

then why was he giving us like over here oh i get it okay

109

so the observer detects any change in value this naturally this thing is going to extend

110

and unextend right yeah but look what happens here

111

this thing turns on and off very quickly

112

so how many it detected two variations of value and on and then an off signal.

113

So that's why this thing's running twice is because it's receiving both an on and off output.

114

Whereas this, it's only going to detect an on and then it powers off when it's on.

115

So I think we can probably do this, but the question then becomes like, okay, so we know how to do all this,

116

but like, how do we actually connect it all up?

117

Now, as you probably saw in the clip, observers were really confusing to us.

118

So we decided to just completely scrap any use of observer.

119

Surely that's not going to be an issue in the future, right?

120

Surely we don't actually need them for anything.

121

Now we had finally kind of come up with a design at this point.

122

It was finally time to start sequencing and building out the door itself.

123

I'm just going to for now hardwire it.

124

Okay.

125

So that's how, so this line is going to only power this one.

126

So this is state one, that's state one done.

127

We then want to power this one right here.

128

Oh, like this.

129

it's gonna go here then i'll add a delay and then it's gonna go into here

130

okay so that didn't work okay slight confession here setting up the timing

131

and everything took us at least two hours and i wasn't 100 sure

132

if i wanted to include it on the video

133

because it was kind of boring but

134

if you are interested in seeing the entire thing i've included the vod in the link in my description

135

if you want to see us torture ourselves for the full duration completely uncut

136

and unedited but

137

if your attention span is fried like mine

138

then here's the basic summary of what happened

139

now at first the main issue

140

they were having was sending the piston at the right time look at this there you go

141

you just needed it to be longer

142

and the biggest issue was sometimes we would have to power

143

the same piston multiple times at different intervals during the sequence this became kind of problematic

144

because there's only really two to three inputs max

145

that you can put on a piston without it powering a bunch of other stuff

146

and we just got a whole bunch of issues with it

147

as well from it just straight up not working to it just looping throughout the entire circuit

148

and basically creating a clock oh wait how did we it was it was all just a complete mess

149

this is the most fucking this is going to be the most disgusting redstone of all time

150

but it's fine we just kind of mindlessly started trying things is there a way to send a directional

151

like a one -way uh thing so the power goes here oh okay i messed this up hold on that's why

152

okay now try

153

yes well okay no now that's not good yeah it kind of got

154

so bad that we just didn't know what was going on at all

155

and we just opted to completely start fresh anyways

156

this is what the design of door number two looked like by the time

157

we were done with it trust me building this thing was way worse so So...

158

Let's get into it.

159

This is going to go.

160

This will travel.

161

And it will do the last subtraction.

162

Got it.

163

Yes!

164

I finished one small fucking fraction of it.

165

Okay, here.

166

Observe.

167

Get it?

168

All right, watch.

169

It's like 90 % done.

170

Right?

171

So then it fills it.

172

It goes, it pushes it in.

173

And then it retracts.

174

Wait.

175

There's a problem.

176

So we have finished...

177

putting it all together.

178

That's done.

179

I just realized everything I was just doing was for fucking nothing.

180

That's right.

181

My dumbass forgot you got to open and close the door.

182

So there was going to be a whole nother step that we would have to do.

183

And unfortunately for us, this wasn't even the biggest mistake I was about to make.

184

So this all, this red line, is the off - Okay, offline.

185

So what we could do is just make it like really freaking long.

186

And just make it like hella delayed.

187

so that like you have ample time to like go through bang bang

188

what uh okay so this will push it this is gonna go there this is going to go

189

and loop through then this is going to be sent up and around where this will now hit

190

and the thing dies because it's a one -way comparator.

191

Now at this point I still didn't really understand how comparators worked

192

so I was just trying a bunch of random stuff and none of it really seemed to be working.

193

But somehow my inability to work with a comparator led me to a new discovery.

194

So basically you do this, do that, that, the power back on and so then it won't continue again.

195

But then how do I repower it?

196

Because this would become like only a one -time thing then, wouldn't it?

197

Yeah.

198

That's the issue I'm running into down here.

199

Because I need these pistons to be activated all the time.

200

Then I need them to shut off so when these pistons go on...

201

Oh yeah, we need to flip the logic, don't we?

202

Yeah, and I'm not sure how to do that.

203

Do you know how to turn off a redstone?

204

torch i don't think you can i'm pretty sure you can i've seen it i've seen it done before

205

i don't know what the i did something check this out

206

i think you short circuited it what did that do

207

Oh, I did it.

208

I figured out not gates.

209

Not gates are going to be very useful in a little bit,

210

but not gates also unfortunately made me realize the big mistake I had mentioned earlier in the video.

211

I just realized the entire door is in backwards logic, though.

212

All of the shit I just made is in backwards logic.

213

Because the door would be closed first, we would open it, and then we would close it.

214

But instead I have made it so it closes first and then it opens.

215

Oh yeah.

216

Dude.

217

Yep, that's right.

218

Your door closes and then stays open.

219

Isn't that an amazing design?

220

This is peak engineering right here.

221

That's what I can say.

222

But yeah, it was unfortunately time to rebuild the entire thing once more.

223

So door number three, here we come.

224

Okay.

225

Dude, I'm gonna cry.

226

Like, I can't believe I just messed that up so badly.

227

Now, even though I was the one to discover, the weird torch mechanic antony was actually the one

228

that put it to use this is always going to be pop

229

then whenever you send another signal it it just switches it so from here it goes to this way

230

right okay so what are you using

231

that for basically this path will be the doors are going to be closed right

232

they're going to be closed always and then

233

when i press the button right they're going to open up now actually the clutch king oh

234

but one small thing we shouldn't have the redstone on the floor

235

but we'll fix

236

that that's fine yeah for now we'll fix

237

it up yeah bam oh nice oh that's clean yes okay

238

now we get to do the fun part

239

now we were kind of traumatized from our last attempt at figuring out the middle block

240

we decided to re -attempt using slime just to do something different

241

but the question is will i actually learn how to use

242

it this time wait why did this not grab

243

it this time though maybe i need like different ones no

244

it's not grabbing it oh wait were you grabbing no no you gotta grab the slime

245

and the slime grabs the iron blocks oh i see yes I finally learned how to use slime correctly.

246

It only took me four hours to realize you placed the slime on the piston, not the blocks, the slime.

247

Wow.

248

Mind -blowing stuff we're learning here.

249

Everyone's saying good job, Skizzle, for not being that dumb four hours later into this project.

250

And what was even better about this is the slime plus

251

the rest of the torch stuff literally ended up just making it so we can redesign the entire system from scratch.

252

And nicely enough, it was far more simple.

253

Our new plan involved just lifting up the entire middle column

254

since it was all going to be connected by slime

255

and we would just chain a bunch of pistons to raise the entire thing up all at once

256

and then it would just drop it once you're through.

257

So now it was going to be easy.

258

Oh, nothing went wrong.

259

Yeah.

260

Okay.

261

I lied it was still kind of hard we don't know what we're doing like I said

262

but what was nice is at this point

263

we just needed to do a double pull to fully lift up the door okay

264

I got step one working look at this bang

265

but everything we had tried up to this point just kept on failing

266

I don't even think it's picking up the first one at all the second one's picking up

267

or the the last one is picking up the second one.

268

The second one is picking up the first one.

269

We decided to simplify our solution even further by removing the bottom block from the slime contraption

270

and just powering it the same way we did with the sides of the door instead.

271

Now I say this, but there was still one really big issue left to solve.

272

Wait, it didn't re -extend?

273

Now we had put ourselves in a weird position here.

274

We needed the bottom one to extend, then the top one to extend,

275

then the bottom one to re -extend once again before the top one un -extend.

276

What ends up happening is if this gets extended before this, this doesn't engage at all.

277

In other words, the entire sequence breaks.

278

So it's just a timing issue.

279

Yeah, so I need your help figuring out that timing.

280

If that's confusing, I don't blame you.

281

It was confusing us too.

282

Now, Anthony had come up with potential solution which looked absolutely crazy

283

so you're gonna see this for example is gonna be one right it's gonna turn on

284

and it's gonna shut off

285

and then it'll turn back on again i didn't get the timing right

286

but that's how you know it's gonna work so power's on right

287

and then boom one of the pistons activates boom

288

and then it shuts off boom

289

and then there's gonna be grace period back on boom

290

and then it'll shut off again

291

but i gotta stop the loop after the second one I just gotta make these regulators longer.

292

And it only got worse from there.

293

What is this?

294

What is this?

295

I turned around for a second.

296

What happened?

297

I don't even know how this thing even works.

298

And so I'm terrified because we haven't tested it even once.

299

It works.

300

If it doesn't work, it's a timing thing.

301

Shall I press the button?

302

Yeah.

303

Did that even do anything?

304

Okay, it's going, it's going, it's going, it's going, it's going.

305

Um, I don't think any of the timing stuff happened.

306

No, it's still going, it's still going.

307

The door already opened and closed.

308

Every new addition to it just made it more of a mess, and we were starting to get more and more desperate.

309

No, no, it was just too long, it was just too long.

310

Because I was expecting it to be a lot longer, like the door.

311

Oh my god.

312

No, bro.

313

I don't think we need a lot of beats.

314

Well, it's because you were the one that was like, it's going to be so long.

315

This was probably going to last like a minute or two.

316

And then when did I say that?

317

Why are we putting this shit on me?

318

Why are we putting this shit on me?

319

Oh my god.

320

No, there just has to be an easier fucking way, man.

321

Look, look, look.

322

Wait, there is an easier way.

323

At this point, I was pretty lost with what Anthony was doing

324

if the random decorations that popped up on the build weren't the sign of that.

325

Instead of continuing to just being a chud watching him,

326

I decided I would just start my own attempt at solving the final timing issue to pull the middle column up.

327

Why does this not work?

328

Now, I just started trying all sorts of things at this point.

329

I was pretty desperate from observers to trying to like depower a redstone torch for whatever reason.

330

It was just throwing stuff at the wall and hoping it worked.

331

But who knows, maybe just mindlessly trying random things may just work.

332

And I kind of got it working.

333

And then it freezes and then you press it again and it freezes.

334

Not anymore, I guess.

335

What?

336

What?

337

What?

338

What happened?

339

Um, perhaps server will work? Did that work?

340

Did that work?

341

Did that just work?

342

Did that just work? Did that just work? Did that just work?

343

Did that just work?

344

Did that just work? Did that just work?

345

oh because there's a change wait we're

346

so dumb right yes wait wait no no because you're right the observer

347

when we were diagnosed uh i was like i was remembering the double hit thing back there

348

and i was like oh maybe we can use

349

that like dude that's that oh my god

350

because then it completely bypasses stupid

351

that i was trying to oh my god i thought

352

it does it it goes yeah like technically the timing is still god awful

353

but like at least it works you know yeah the observer is your you are wires

354

and then the the this guy yeah i'm gonna be

355

so honest i barely understand how this thing works i think

356

it's fair to say we got very lucky

357

we randomly decided to do observers got confused by it five hours ago

358

and then i just was like you know what might as well try it

359

and somehow it works we take those that's that's engineering for you i guess

360

but now comes the easy part it was just setting up the rest of the sides of the doors

361

that we already knew how to make from a while ago i thought we were going to do the ground

362

dude i do not do it do you care

363

and it was finally time to do our final test to see

364

if our three by three piston door actually fully worked i'm going to truth yeah Do the honors.

365

I'll be the one to walk.

366

Oh my god.

367

That's beautiful.

368

We did it.

369

Oh my god.

370

Dude.

371

We did it.

372

Ignore all of this.

373

Whatever the hell you created.

374

Whatever the hell I made.

375

Oh my god.

376

Dude, there's a fucking llama on your shit doing like spins on it.

377

I can barely reach the button.

378

Go fast.

379

Alright, we're in.

380

No!

381

No!

382

Now, four by four.

383

I don't think so.

384

I mean, I was gonna have us do flying machines, and I was gonna have us make like a farm.

385

So maybe we can do that as like engineers versus

386

Minecraft redstone too.

387

if this video does well, so that's up to you guys.

388

But yeah, um...

389

This is - this is - I don't know how long the footage is gonna be, or like the final video will be,

390

but this is gonna - this was like a six hour record.

391

I thought this was gonna be 30 minutes!

392

Alright, we can call for today.

Pronuncia a cui fare attenzione

Chi parla usa 103 contrazioni e forme ridotte, come don't, gonna, I'm. Pronunciale nella forma breve, così come le senti.

I suoni “sh” e “zh”: duration /dʒʊˈɹeɪ.ʃən/, variation /ˌvɛəɹiˈeɪʃn̩/, orientation /ˌɔː.ɹi.ənˈteɪ.ʃən/, fraction /ˈfɹæk.ʃən/, collision /kəˈlɪʒn̩/
Parole lunghe — attenzione all’accento: technically /ˈtɛk.nɪˌkəl.i/, naturally /ˈnæt͡ʃ.(ə.)ɹə.li/, electrical /ɪˈlɛktɹɪkəl/, experiment /ɪkˈspɛɹ.ə.mənt/, accidentally /ˌæk.sɪˈdɛnt(ə)li/

I suoni difficili per chi parla italiano:

/h/ — va soffiata, non è muta: honey /ˈhʌni/, whereas /(h)wɛɹˈæz/, whatsoever /ˌ(h)wʌtsoʊˈɛvɚ/, handler /ˈhænd.lə/
Consonante finale — senza aggiungere una vocale dopo: extend /ɛkˈstɛnd/, sequence /ˈsiː.kwəns/, torch /ˈtɔːtʃ/, confuse /kənˈfjuːz/, gate /ˈɡeɪ̯t/
/æ/ — più aperta della “e”: bang /ˈbæŋ/, mechanic /mɪˈkænɪk/, scratch /skɹæt͡ʃ/, activate /ˈæktɪˌveɪt/, backward /ˈbækwɚd/

Cos'è la tecnica dello Shadowing?

Shadowing è una tecnica di apprendimento delle lingue supportata da studi scientifici, originariamente sviluppata per la formazione dei traduttori professionisti e resa popolare dal poliglotta Dr. Alexander Arguelles. Il metodo è semplice ma potente: ascolti un audio in inglese di madrelingua e lo ripeti immediatamente ad alta voce — come un'ombra che segue il parlante con un ritardo di solo 1–2 secondi. A differenza dell'ascolto passivo o degli esercizi di grammatica, lo shadowing costringe il tuo cervello e i muscoli della bocca a elaborare e riprodurre simultaneamente i modelli di discorso reale. La ricerca dimostra che migliora significativamente la precisione della pronuncia, l'intonazione, il ritmo, il discorso connesso, la comprensione dell'ascolto e la fluidità del parlato — rendendolo uno dei metodi più efficaci per la preparazione alla prova di speaking dell'IELTS e per la comunicazione reale in inglese.
