I Built a Dog Catapult — Transcript

Full transcript

1. 0:00Why do Asian people look like that?
2. 0:02Well, I've got some theories.
3. 0:15[music]
4. 0:18>> This is my girlfriend's dog, Dinky, and
5. 0:20I love him. He [music] does bark at me
6. 0:22non-stop, even though I've been with him
7. 0:23since he was a puppy. Great dog. Still,
8. 0:25unrelated [music] note, you ever just
9. 0:26want to build a catapult? You ever just
10. 0:27want to go to the Home Depot and buy
11. 0:28some wood and then build a freaking
12. 0:30catapult? [music] Two completely
13. 0:30unrelated things. And leg would look at
14. 0:32that. We're here. I was doing some
15. 0:33research on how to build a catapult. I
16. 0:35tried chatting teeth, but [music] it
17. 0:36didn't really help that much. But then I
18. 0:38found this picture of a catapult on
19. 0:39Google images, and I feel like that's
20. 0:40good enough. It's mostly wood. Why
21. 0:42should it shoot dogs in particular? I
22. 0:43mean, it could be anything. It doesn't
23. 0:44have to shoot dogs. I just think it
24. 0:46would be kind of interesting for the
25. 0:47YouTube scientific community.
26. 0:51Where is bunching cords? [music]
27. 0:56>> Catapult time. Do you guys like it? Do
28. 0:58you think it's freaking sweet? Yeah, it
29. 1:00turns out it's actually not that hard to
30. 1:01build a catapult. It's really just
31. 1:02mostly wood. I kind of just went Red
32. 1:03Dead Redemption 2 Amish style on it.
33. 1:06Probably going to have to test it inside
34. 1:07because I moved into a new garage.
35. 1:09There's no yard at this place. I moved
36. 1:11in with Lily and it's been going
37. 1:12perfect. Almost perfect.
38. 1:16Anyways, let me show you. Got like a
39. 1:17rubber hose that I found. I like this.
40. 1:19This is pretty cool. It's a doorork knob
41. 1:20that we had lying around. Turn the
42. 1:22doorork knob. Boom. Fire.
43. 1:24>> Hello. Hey, look what I built.
44. 1:26>> What is that?
45. 1:27>> Catapult.
46. 1:27>> For what?
47. 1:28>> Uh, look for launching stuff.
48. 1:29>> Like, what do you What are you
49. 1:31launching?
50. 1:32>> I got some uh fruits.
51. 1:37>> Holy [ __ ]
52. 1:39>> A man.
53. 1:40>> What are you trying to
54. 1:42>> I just want I want to fling like
55. 1:43something [music] [ __ ] far.
56. 1:46>> So random. [laughter]
57. 1:47Bye.
58. 1:48>> Bye.
59. 1:52>> [music]
60. 1:52>> Now, the astute among you might say,
61. 1:54"Hey, that just looks like a normal
62. 1:55catapult." And if I had it my way,
63. 1:57[music] I'd sentence you to 10 years
64. 1:58hard labor just for saying that. But I
65. 1:59do agree it could be cooler. Like, what
66. 2:01if it shot automatically [music] certain
67. 2:03objects or animals, you know, could be
68. 2:05anything. So, I have a shitty webcam
69. 2:06setup and we're going to write some
70. 2:07Python to look out of it. Going to make
71. 2:08a camera object. Run it. Nice. We're
72. 2:11just going to capture that over and
73. 2:12over. And now that we have a video feed
74. 2:13going in Python, I want to detect if
75. 2:15there's a dog anywhere in the frame or
76. 2:16anything. It could be any object. We
77. 2:19could make a model to do that ourselves,
78. 2:20but I think instead we're just going to
79. 2:22steal one.
80. 2:24We're just going to steal one. Go ahead
81. 2:26and run that bad boy. And uh that's not
82. 2:28detections, that's numbers. Yeah, you
83. 2:30still got to draw the boxes yourself
84. 2:31like a [ __ ] caveman. But after that,
85. 2:33it works fine. I made a bunch of
86. 2:34different colors for each different
87. 2:35object. You should probably test it on
88. 2:37the real thing.
89. 2:39>> Yeah. No, I know. Yep. Yep. Good boy.
90. 2:41Good boy. Yes. Yes. I'm going to shoot
91. 2:44you off the roof, pal. I'm gonna send
92. 2:46you to [ __ ] space. But first, we got
93. 2:48to get this code off my computer onto
94. 2:49the catapult, which is going to be hard
95. 2:51because it's all the way over there. And
96. 2:52also, it's made out of wood. Hey, so
97. 2:54it's been a couple weeks since that last
98. 2:56bit. And oh man, I I I don't know how
99. 2:59this keeps happening to me. I had to run
100. 3:00the code, so I threw in a
101. 3:01microcontroller, but then I needed a box
102. 3:03to put the microcontroller in. So, I
103. 3:05ordered an electronics enclosure on
104. 3:06Amazon. And after a night of peaceful
105. 3:08soldering, it was looking really good.
106. 3:09Then, I needed some way for that to
107. 3:10trigger the catapult firing. And so my
108. 3:12next idea was I feel like I'm doing a
109. 3:14[ __ ] MIT maker portfolio rejected.
110. 3:17What the [ __ ] am I talking about? Oh,
111. 3:18firing mechanism. This was my first
112. 3:20idea. Pretty much all it does is you
113. 3:21pull the catapult arm back with a rope
114. 3:23and this severs the connection to that
115. 3:24rope, which is a super good idea. Is
116. 3:27what I thought it was. Yeah, it turns
117. 3:28out even a 4ft tall Filipino boy is too
118. 3:31heavy for the shitty piston to handle.
119. 3:32So instead, I built this metal hook type
120. 3:34of thing. I got the idea from those 3D
121. 3:36animated how a gun works videos. And I
122. 3:38have no idea why this one works and the
123. 3:40last one didn't. If any physics people
124. 3:42have an answer, type it in the comments
125. 3:43and then immediately delete it. I don't
126. 3:45need that [ __ ] nerd [ __ ] I added a
127. 3:46bunch more [ __ ] too, like this winch.
128. 3:48Okay, this is test number [ __ ]
129. 3:50whatever.
130. 3:55And then I take this off
131. 3:58and I added a camera to see the object.
132. 4:00But a lot of it's unnecessary. I do this
133. 4:02thing when I build stuff. I just keep
134. 4:04adding [ __ ] on to it even though the
135. 4:05main bit is done. And it's cuz I don't
136. 4:07want to stop building it cuz it's fun.
137. 4:08But a lot of the time it just makes the
138. 4:10overall product worse. [music]
139. 4:13>> But not this time, baby. Look at this
140. 4:16thing. Look how [ __ ] cool it looks.
141. 4:18You could launch literally anything with
142. 4:20this. The wind just makes Oh my god,
143. 4:22that is so [ __ ] loud. Just makes
144. 4:23things so convenient. No matter how hard
145. 4:25you want to fling your dog. Hey, editor
146. 4:27Michael here. It looks like I was so
147. 4:28excited to tell you what the catapult
148. 4:30does that I forgot to tell you uh what
149. 4:32the catapult does. How did that happen?
150. 4:33[ __ ] if I know. I made it so it can fire
151. 4:35itself automatically depending on what
152. 4:37object it sees. So, it's always watching
153. 4:38its firing zone, like where do you load
154. 4:40in the objects, and it just waits until
155. 4:42it sees something that you told it to
156. 4:43fire. It'll do everything for you. All
157. 4:45you got to do is put in the object you
158. 4:46want to launch. Or maybe the object
159. 4:48wanders in. Maybe the object wanders in
160. 4:49cuz I smeared a little bit of peanut
161. 4:51butter at the bottom of the launching
162. 4:52zone. Anyways, hope that cleared things
163. 4:53up. Now, to transition back to the
164. 4:55video, I have to say power. Speaking of
165. 4:57power, the maximum bungee cords we tried
166. 4:59was two, and it blowed up. So, I'm
167. 5:01thinking like six.
168. 5:04>> Climb up a ladder with a hammer and a
169. 5:06nail. Oh my god. What does that mean? If
170. 5:09all my weight can't pull it back. Oh
171. 5:11[laughter] no. We should probably test
172. 5:13it. All right. I'm going to go ahead and
173. 5:15arm it. It's going to know when to stop
174. 5:17because when the arm touches the spring,
175. 5:19these two wires are going to touch and
176. 5:21complete a circuit. Thank god it worked.
177. 5:23And now it's primed.
178. 5:26[ __ ] That's probably fine. Now you'll
179. 5:28see the vision system. I have it set up
180. 5:29to detect uh fruits like bananas and
181. 5:32apples, but you could really type
182. 5:33anything you want in there. And if you
183. 5:35look at the camera, we got like this.
184. 5:37Hey, [music] I'm Michael and I'm here to
185. 5:39tell you about timers. No, not that kind
186. 5:41of timer, silly. I'm talking the timers
187. 5:43we use in [music] software. See,
188. 5:44software runs pretty fast. So, if you
189. 5:46forget to slow things down with a timer,
190. 5:48like [ __ ] over here. Then the exact
191. 5:50frame that your fruit [music] touches
192. 5:51the catapult's firing zone, it's going
193. 5:53to go off. And that's a recipe for
194. 5:55disaster. And if you look at the camera,
195. 5:56we got like this. OH, [ __ ]
196. 5:58>> OH, I'm going to be finding banana for
197. 5:59the rest of my life. Hey, Lily, come
198. 6:01here real quick.
199. 6:03>> It's a catapult. Oh,
200. 6:04>> you want to see it shoot?
201. 6:05>> Okay. Where are you going to put it?
202. 6:06>> This freaking watermelon. When I put the
203. 6:08watermelon in, we got a few seconds cuz
204. 6:10I put a timer on it this time. Oh, [ __ ]
205. 6:12It's okay. It's okay. It's okay. It just
206. 6:14thinks the rubber band's a banana.
207. 6:15>> Yeah. Look, I'm genius.
208. 6:17>> Look at that. Excuse the watermelon.
209. 6:18Great.
210. 6:24[screaming]
211. 6:25>> My light.
212. 6:27>> It was cool though, right?
213. 6:28>> It's cool, but your light's [ __ ]
214. 6:30>> You can shoot all kinds of things with
215. 6:31this. Will you shoot Dinky? Yeah, he'd
216. 6:33die.
217. 6:34>> Yeah, he'd die.
218. 6:35>> Okay, bye.
219. 6:37>> No, we're not doing that again. Now,
220. 6:38what we got to do is Well, I I got
221. 6:40another watermelon. POV, you're my
222. 6:42girlfriend's dog.
223. 6:50It works. Now I can finally do [music]
224. 6:52what I've been planning this entire
225. 6:53time. I'm going to launch this little
226. 6:56stick to play fetch with Dinky. And
227. 6:59hopefully we'll bond enough where he
228. 7:00doesn't feel the need to bark at me. So,
229. 7:01let's take this thing outside and Oh.
230. 7:08Oh, that is a shame. And I can't change
231. 7:11it back. The catapult only shoots dogs
232. 7:13now. So, the next logical step, make a
233. 7:14dog out of ballistics gel and launch it.
234. 7:16And you might say, "Michael, what the
235. 7:18fuck?" But I just want to make sure
236. 7:19because if a dog wanders into the
237. 7:20catapult, I don't want it to get hurt. I
238. 7:22want it to [ __ ] die.
239. 7:25They do sell ballistic gel online, but
240. 7:27weirdly enough, not in the shape of a
241. 7:28dog. So, to make our own, we're going to
242. 7:30need a three print mold. Coat the inside
243. 7:31with high heat epoxy. Put a hole in it.
244. 7:33Not like that. Put a condom in it. Not
245. 7:35like that. The the condom is full of
246. 7:37salt water so that it is negatively
247. 7:39buoyant when I pour the gelatin in the
248. 7:41dog so that there's a cavity for the
249. 7:43blood. It's It's all fine. Then clamp it
250. 7:45together. Pour a bunch of boiling
251. 7:46gelatin in. Then set it in the fridge at
252. 7:49my friend's house. I'm glossing over
253. 7:50maybe 90 hours of work. But what matters
254. 7:52is that it's ready to come out of its
255. 7:53mold. And I know the results are going
256. 7:55to be worth it.
257. 7:56>> It's deformed.
258. 7:57>> No. Happy birthday.
259. 7:58>> Maybe I can just glue it back together.
260. 8:00You can.
261. 8:01>> This is my beautiful baby boy. He may
262. 8:03not be perfect, but [music]
263. 8:06also I made two of them.
264. 8:09>> Now, I know these guys are going to get
265. 8:10launched out of the catapult really
266. 8:12[ __ ] fast, but I don't know how fast,
267. 8:14like mathematically, but I think I know
268. 8:17someone who does.
269. 8:19>> Hey, what's up, man?
270. 8:20>> How we doing?
271. 8:21>> I got a catapult that I built, and I was
272. 8:23hoping you could tell me how to
273. 8:25calculate how strong it is.
274. 8:26>> Uh, are we recording?
275. 8:27>> Yeah. If this is a possum launcher, I'm
276. 8:29out. Michael, I just want to say that
277. 8:31out of the
278. 8:32>> promise it's not a possum launcher.
279. 8:33>> Despite his suspicion, Marcus still
280. 8:35agreed to help me with the math, but it
281. 8:37was not going well.
282. 8:38>> So that's jewels. So that's work. So
283. 8:40that's 1,800 jewels. You're left with a
284. 8:42velocity.
285. 8:43>> Dude, what's it difference between a
286. 8:44jewel and a newton? Is it okay if it's
287. 8:46negative?
288. 8:47>> Um, nope. Definitely not okay if it's
289. 8:49negative. And you said it's not possums,
290. 8:51but we could say it's nothing
291. 8:53biological.
292. 8:54>> [ __ ] [ __ ] [ __ ] How does he know? I
293. 8:56have to distract him fast, [music] so I
294. 8:58arm the catapult. Luckily, a band snaps
295. 9:00and catches his attention, which allowed
296. 9:02us to finish math time.
297. 9:03>> I got 19.8.
298. 9:05>> That feels right to me.
299. 9:06>> I still am trying to get like an idea
300. 9:08for what will that do to the dog.
301. 9:15>> All these equations don't work if it's a
302. 9:17dog. Oh, wait. You actually are
303. 9:18launching it from in the ground.
304. 9:20>> Yeah. I want to test your [ __ ]
305. 9:21equation. Yeah, I want to test your
306. 9:22equation.
307. 9:32Is [clears throat] that the head?
308. 9:33[laughter]
309. 9:33>> Yeah, Mark, it is the head. And it
310. 9:35definitely didn't go 19.8 m or like
311. 9:38[music] 3 ft. So, I don't know. We just
312. 9:40have to launch the dog for real. Let's
313. 9:41get this catapult on the roof.
314. 9:42>> What the [ __ ] is this
315. 9:43>> catapult? You like it? Uh, we got to put
316. 9:45it on the roof tonight.
317. 9:47>> Up there?
318. 9:47>> Yeah, we actually have to put it on the
319. 9:49roof tonight.
320. 9:50>> Really?
321. 9:50>> Yeah. [laughter]
322. 9:51>> Don't let it Don't let it hit the wall.
323. 9:53We should keep these ropes, huh? [music]
324. 9:55>> Yeah. So, when we hang ours open, this
325. 9:56doesn't work.
326. 9:57>> Cool. We got the catapult on the roof.
327. 9:59Tomorrow, I'm going to grab Lily and
328. 10:00Dinky and we're going to show him what
329. 10:01happens when he barks.
330. 10:02>> Is this related to the pawsome catapult?
331. 10:05>> What? Catapulting a possum high into the
332. 10:07air? Are you [ __ ] kidding me? This is
333. 10:09disgusting. This is horrible. No, we're
334. 10:11launching [music] dogs, not possums.
335. 10:12This is No, that's too far.
336. 10:16>> Hey, Lily, can I take you somewhere? I
337. 10:18guess I'm going to show you.
338. 10:19>> What is this?
339. 10:19>> Bring the dogs.
340. 10:20>> Bring the dogs?
341. 10:21>> Yeah, bring the dogs. What do you mean
342. 10:22bring the dog? Why would I bring the
343. 10:24dog?
344. 10:25>> Oh, a GoPro camera. Why the [ __ ] am I
345. 10:28bringing them?
346. 10:28>> Cuz they love it. What do you think the
347. 10:29surprise is?
348. 10:31>> A proposal. Ooh, it better be something
349. 10:33better than a proposal then. You know
350. 10:35what I mean?
351. 10:35>> You know what? I think it is.
352. 10:37>> We're here. Okay. What is that?
353. 10:40>> This is what happens to dogs that bark
354. 10:42at me.
355. 10:44>> Michael, this is what happens to dogs
356. 10:46that bark at me. Why should anyone have
357. 10:47to suffer through the barking that Dinky
358. 10:49does? through through the barking of any
359. 10:51dog. Just [music] you wait until there's
360. 10:52one of these dog truckers on every roof
361. 10:55across the country in America.
362. 10:56>> Michael, I'm okay. I
363. 10:58>> of any dog.
364. 10:58>> Come down. It's You don't think this is
365. 11:00going a little too far? Like
366. 11:02just a little bit. Dogs bark. You love
367. 11:05the Vinky. [music]
368. 11:06>> I I love him.
369. 11:07>> Yeah. So, come down from there. Come
370. 11:09down.
371. 11:09>> I do love him.
372. 11:11>> Yeah.
373. 11:11>> That's why I'm going to show him what
374. 11:12happens when he barks.
375. 11:13>> Oh my [ __ ] dog.
376. 11:14>> Finally, after months of planning, I'll
377. 11:16[music] show all of you what happens to
378. 11:18dogs that bark at me.
379. 11:21Finally. Finally.
380. 11:27[music]
381. 11:34>> The blood splatter is too realistic.
382. 11:36[laughter]
383. 11:39DOGS BARK. THAT'S WHAT THEY DO. I MEAN,
384. 11:42I saw it already.
385. 11:42>> I want I want him to see. I want him to
386. 11:44see. Oh no. This dog must have barked.
387. 11:47Okay, that went perfect. I'm going to

397. 12:09>> You may have also noticed the awesome
398. 12:10copyrighted music throughout this video.
399. 12:12I was able to do that with a technique
400. 12:13called uh not making any money. I just
401. 12:15wanted to use some [ __ ] awesome
402. 12:17music. Okay. Is that stupid? Yes. Uh but

404. 12:20copyright strike immediately. So, if you

418. 12:44too. Kind of. Lucky for us, there's
419. 12:45today's sponsor, Odo. [ __ ] I'm so
420. 12:47dizzy. Odo is the all-in-one solution
421. 12:49for business. [music] They have apps for
422. 12:51accounting, CRM, inventory, sales, etc.
423. 12:54Say I have a business, and it's uh
424. 12:55delivering dogs to your house, straight
425. 12:57to your house, uh via catapult. They
426. 12:59have an app to help me plan my products.
427. 13:01Another app that manages inventory. Just
428. 13:02imagine how much inventory my company
429. 13:04has. And this one's cool. You can use a
430. 13:05barcode scanner to keep track of
431. 13:07products even easier. And then an app to
432. 13:08manage and track sales so that my
433. 13:10company can function as efficiently
434. 13:12[music] as humanly possible. At the end
435. 13:14of the day, if you have a business, they
436. 13:15probably have something that can
437. 13:16streamline it even more. And the great
438. 13:17part is you can select only the apps
439. 13:19that you need. ODU is super easy [music]

443. 13:25else? One app free for life. I like ODU
444. 13:27because uh they let me put the ad at the
445. 13:30end of the video and a suite of software
446. 13:32and applications. Oh my god, they let me
447. 13:34put the ad at the end of the video.

449. 13:36at the end of the video. So, thanks
450. 13:37again Odo for supporting the channel.
