DIY Monster in a Box Halloween Prop Tutorial

[@m.maclellan7147]

Very nice ! Cool to see someone without a tricked out shop making something cool !

[@miguel2day]

This is a sick video. I am totally going to make a box like this for Halloween this year.

[@royjumonville7026]

That's the best showing o n how to make the "Monster in a box" I've seen. I've been looking for a good showing so I could make one and yours is, by far, the best. Step by step instructions. Thanks for such a great job making the video.

[@UndercoverMonsters]

+Roy Jumonville You're welcome. Good luck on your project.

[@jerryparrino9513]

I love that he drew on his hand Halloween things before he made this video

[@OakLaneCemetery]

Gearing up to do this project soon. I might try 2 wipers with only 2 protrusions on the cams to see if I can get a more random banging. I'm thinking one wiper on slow speed and the other on high. I have a crate already, but I'm just brainstorming at this point.

[@spookyspectacle]

This is AMAZING!! This is going to be more first year making a haunt and I am definitely going to try to recreate this because man it will blow people's minds!

[@rhysnybo3420]

Wow epic animictronic monster box love the make of it and love the machanics of it as well good work on it

[@mookzmom]

Great job. Your kitty was wondering when you were gonna be done making her box for her. 😂

[@theflandersons]

Can you describe how the mp3 player and computer speakers work with the motion sensor? Do you leave the mp3 on a loop and only turn the speakers on and off with the sensor?

[@isometrixk]

I had the same question but he answered this question somewhere else: "It's just on a loop and it is playing nonstop but the speakers are what get triggered to turn on/off by the motion sensor. Plug your motion sensor into a power strip and everything else you want to turn on/off into that power strip."

[@jackiebanks2210]

finally got to sit down and watch this and am glad I did. Hopefully I can get one made for next year.

[@UndercoverMonsters]

Well if you have any questions, i shall be here.

[@johnchall6796]

Undercover Monsters What was the length of the wood boards?

[@UndercoverMonsters]

john hall I don't remember off the top of my head, i would have to re measure the box. It really doesn't matter the length though, it's a matter of personal preference on how big you want the box.

[@johnchall6796]

ok thanks

[@kabralbi2167]

That’s cool! Need to build one for this year 🤩 looks great. Subscribed 👍👍👍

[@deadandrottencreepylover6267]

Nice detailled video man,keep it up .Greetings from The Netherlands

[@UndercoverMonsters]

+SuperELVISfan The King Thank you man. We will try our best.

[@rey210rey]

Awesome prop..U make it look so easy

[@EerieAcresCemetery]

I like the idea of the nylon roller for the cam! Great job!

[@UndercoverMonsters]

Eerie Acres Cemetery thanks!

[@joeminson6763]

Great prop! Excellent video!!

[@alexanderneumann5267]

Awesome project….Thanks for sharing.

[@no-uh5mf]

OMG THIS IS SO COOL! Our house is known for the scariest Halloween props in the neighborhood and I think I should add this to it! P.S. I Love your Cats! 🐈

[@UndercoverMonsters]

Do it! It scares the crap out of the little ones!

[@southbrickcitycustombuilds2700]

FoxGirl55 I have the best nod scariest props in my neighborhood

[@ProfessionalPainterDecorator]

i take it that it will run for the length that the motion sensor is set for... test, 1min, 5mins etc etc?

[@tommysdiy582]

Dude, that is so cool

[@randywilson4529]

Totally Rad build that monster in the box, thanks for sharing will differently be building one of these for next year

[@greenidguy9292]

Next project: a proper stand for my mitre box. 😂😂

[@Sandcem]

Great detail on vid love it. Good to show the mistakes or awkwardness, we all go through it ha!

[@UndercoverMonsters]

+SandricCemetery (SandCem) I wasn't sure how to make a tutorial on a project that takes so long, so this was the best i could do. I'm glad you enjoyed it.

[@UndercoverMonsters]

+SandricCemetery (SandCem) Also we have 4 videos in stock for October this year so stay tuned! The new one will be up later today.

[@MrJhobb75]

I knew it! Plaster molds make great counter weights for mitre saws..

[@roberttrakofler9307]

awesome prop! best box ive seen

[@UndercoverMonsters]

Why thank you!

[@jeremiahanderson5374]

Cool stuff man! I’ll have to give it a go!

[@bransonhauntedhills]

That turned out great. Thank you for sharing.

[@UndercoverMonsters]

bransonhauntedhills You are welcome. Subscribe for future videos.

[@bransonhauntedhills]

I am subscribed and looking forward to more of your videos!

[@joltagegyronicthehedgehog4911]

I wish to build something like that

[@MrDudley724]

Dude that was bitch n! Got some great ideas! I was looking at going the pneumatic route. But I like how self contained the entire system is. Liked and subscribed all day long! ☠️💀🔪⛓

[@CarlosChavez-km9pg]

that is so cool im gonna steal ur plans to build my own

[@UndercoverMonsters]

That's why i made this video!

[@sptfr987]

What did you use to run the wiper motor to the power outlet

[@MrDudley724]

Couldn’t find your link on the motion sensor build! I could probably figure it out. Heard garage door sensors work well since they don’t require a heat signal?!! But little more complex to wire up.

[@michaelmoss5476]

Looks great, I have made several props but never a Monster in a box. I am wondering if uneven spacing on the cam might make for an interesting effect. boom..boom.........boom........boom..boom........boom, etc. I will add this to my 2017 todo list. Great video -- Thanks for posting!

[@UndercoverMonsters]

I think you would have to put a cam at the bottom of the box with a hole cut out so that part of the cam touches the floor. That may very well work, but the box is pretty heavy. I did just see a video recently where someone made a box like that, pretty sure it's on the tube.

[@BrightSparkIdeas]

Nice video, looks great

[@olegariochapa8124]

way cool! two thumbs up!! 👍👍

[@UndercoverMonsters]

Are you planning on building one?

[@sportyjeff84]

Can u share a link for the motion sensor

[@meme-yp7xr]

Orange kitty! Mine hangs out too while i work .

[@titan142]

Hey there, I'm trying to replicate what you've done, but the problem I keep running into is that my cam keeps stopping on the hasp and not turning, eventually falling off of the wiper motor (coupling bolt unthreads and gets so loose that it wobbles off). I believe I've done everything like you have done, but I don't know what I'm missing. I moved the motor more closer to the front of my lid and put the hasp closer to the front as well. I'm using an old steamer trunk that's relatively lightweight but thought maybe the lid was too heavy. That worked for about 20 seconds then the same thing happened. I took some pictures for reference if there is a way to send them to you, but I'm also wondering if I need to move the cam lower so just the edges of the fins/spines are hitting the hasp maybe? I'm also about to loctite the coupling bolt onto the motor threaded shaft, but wanted to reach out first. Thanks for your help and the video.

[@LisaMontgomery79]

Great job!!!!

[@GSimon850]

brilliant dude

[@MrHartApart]

two things.. first i wanna see if im right about the mp3 player. you leave that running throughout the haunt and once the power strip fires up the speakers thats when you hear it just slam on no delay? second.. the motion sensor.. would you use one of those over a step pad pressure sensor? *my only fear is the step pad is for more 'burst,' effects and not anything that last longer than you being on the pad. other than that, thanks a bunch for the tips on how to build everything, its coming along quite nicely!

[@UndercoverMonsters]

MrAnderson1985 You are right about the mp3 player. For the sensor, if you are going to use a step pad, i would place it a around the corner or several feet from the box so that it has time to kick on properly. But i like to use a motion sensor instead of a step pad. You can place the motion sensor anywhere and it instantly kicks on.

[@crustyknight]

Undercover Monsters A comment on motion sensors, I found they were rather hit or miss unless you had a strong light source. I ended up buying a bunch of 2 and 3 dollar flashlights from Harbor Freight. Duct taped them to a spike, placed the cardboard tube from a toilet paper roll over the light end. This helped focus the light while at the same time hiding it in the dark. Unless you looked right down the light beam you couldn't see it. The batteries lasted all night and it never failed to trigger my prop.

[@UndercoverMonsters]

Papa McCain that sounds cool, although I've never had a problem with my motion sensor.

[@and122004]

I love it, I'm building my own but I'm having a bit of a problem with the motor. Would really appreciate some help if you can.

[@UndercoverMonsters]

+Daisy Ramirez What problem are you having?

[@daisyramirez4244]

+Undercover Monsters my motor isn't spinning fast it goes really slow like half an inch turn every 2 seconds. I don't know what might be causing that.

[@UndercoverMonsters]

Did you get this same motor? It has two speeds. The green wire is slow and the blue wire is fast.

[@daisyramirez4244]

+Undercover Monsters yes I've tried it both ways and still does the same thing

[@UndercoverMonsters]

Daisy Ramirez does it move the same speed on both wides? I mean it moves sort of slow in general, that is why I built the cam system.

[@m3rdpwr]

What are the overall dimensions for this box you made? Thank you!

[@niceastuffa]

Nice build built my own but made it 12 volt dc so I could move it around I will post it soon under magician frank paris

[@harrykuheim6107]

I just made my first one! I made mine a Congolese Honey Badger in a Box !

[@ellielamb6568]

I love this.. I have never done anything mechanical. I would love to try. Where should I look for a wiper motor? Auto parts store?

[@c0pyimitati0n]

Read the notes section...

[@UndercoverMonsters]

+Ellie Lamb Click 'show more' to see a list of parts. This was my first time building anything like this, and i love how it turned out. Happy Haunting!

[@jttaylor5236]

Very nice.

[@grampinator]

OMG This is so cool !!!!

[@UndercoverMonsters]

Go build it! ;)

[@grampinator]

I tried. Mine was not a success. But I had sound effects. Yours is a Michelangelo creation.

[@Zeisslermusic]

Cool, scary i will make the box for next halloween 2019 :-)

[@brianbrun5169]

That's a great video. The only question I have is about the MP3 player. What type of player do need that will automatically play the mp3 when power goes on to the rest of the box? Are you following me? Do you just have the player set to loop an mp3 sound and you get the sound only because the speakers are receiving power? In other words, the MP3 player is not turning on and off all the time when the power goes out?

[@michaelmoss5476]

This isn't my video, but I do just what you said here. MP3 player on a loop playing a single scary sound. Obviously this wouldn't work for any kind of dialog, but for scary noises, witches cackles, monster growls etc, this effect works just perfectly. Whatever triggers my prop will also power the speakers on and then off again. Also, an MP3 player with a USB connector is ideal so you do not need to worry about batteries running dead half way through Halloween night.

[@UndercoverMonsters]

You've got it!

[@steveforwarduk]

I've been racking my brains for months now trying to figure out how to get a PIR sensor to trigger both the lights AND the audio.. I can't believe I've been so stupid!. of course, use the powered speakers ON/OFF to trigger the audio.. genius!.. saves me having to buy any audio fx board.. of course, you're right, you cannot have any pre-prepared dialogue as you never know when it's going to be the right time etc.. but as you say, for audio fx, it's perfect.. thanks!

[@rogeliodelarosa7927]

Awesome

[@northernmaine2020]

how do you know where the negative and positive is on the wiper motor

[@ache4dalake]

Very cool. Thx.

[@UndercoverMonsters]

+ache4dalake I hope this helped you out.

[@maw19_72]

Cool 👍

[@fragolegirl2002]

Where is the link to learn how to make the sensor? 22:56

[@airballon_artscrafts641]

Amazing keep it up

[@UndercoverMonsters]

+Arts&Crafts DIY Thanks :)

[@Kana7782]

very nice! about how much did everything cost?

[@UndercoverMonsters]

+Kana7782 I don't remember off the top of my head. The parts list is in the description if you want to add it up. The most expensive part was $25 for the wiper motor.

[@4theloveofDub]

Question, How did you get the MP3 player to only play the sound while the box is "on"? All MP3 players I have seen are battery powered and will continue to play even if unplugged... on that same note, how you get it to turn on when the box turns on? most MP3 players you have to press "play" after they get power before they will start playing

[@UndercoverMonsters]

It's just on a loop and it is playing nonstop but the speakers are what get triggered to turn on/off by the motion sensor. Plug your motion sensor into a power strip and everything else you want to turn on/off into that power strip.

[@sidwalker6902]

So what was the reason for sanding?

[@afumario2]

Is there any way I could get someone to build this for me? Need it but don't have the time.

[@northernmaine2020]

hey where did you get your monster sounds

[@djzayelmulaton]

What length did you cut the wood?

[@Pam66127]

Hi where did you get the 8mx1.25 coupling nut Home Depot or Lowe`s did not have.

[@UndercoverMonsters]

Home Depot is where i buy most things.

[@eddieharris3150]

Um.. why did you sand them if u were going to tear them up anyway

[@loctuz]

thank you

[@UndercoverMonsters]

+loctuz You're welcome. I'm glad i could help out.

[@ChrisYarzab]

You left out important details. You mention a wiper motor but forgot to show us what it looks like or how it operates before installing it. It would have been helpful so I will have to look elsewhere. Thanks for sharing.

[@craigpiatt1136]

What all did you use for the motion trigger

[@zx6rracer1]

Would like to know this also.

[@baculpojl]

Sick

[@UndercoverMonsters]

+Jeremiah Baculpo I'm glad you liked it.

[@baculpojl]

I'm working on making something similar but I was thinking of using a corded drill from harbor freight and use a wire tie to partially depress the trigger.

[@UndercoverMonsters]

Jeremiah Baculpo I tried that and it was a waste of money, in my opinion. The drill doesn't have enough torque and it is really loud.

[@squishface3595]

Only thing that would have made this better is if you shook the treat bag and gathered the pets before you turned it on.

[@UndercoverMonsters]

hahaha i didn't think of that

[@H4x0r1]

Can I get the Dimensions of the box please!

[@UndercoverMonsters]

You can build it however big you like, i don't know the dimensions off the top of my head. Or even easier is to look for an old trunk at a salvation army/goodwill/antique store.

[@susanpierce-rimbey6012]

this is so awsome (=])

[@maxmt4325]

Attaching the cam to the motor is ridiculous. First time stripped the bolt on the motor.

[@sturggaming6759]

Complete with drug overdose wrist slitting emo music sold separately

[@twisted516]

Doing a lot of extra unnecessary work

[@vegasprepperone]

terrible backround music dump it !

[@hd2kill]

Great vid , loved the tunes

[@UndercoverMonsters]

+hd2kill Thanks. The music is from a friend's band, Kenoma.
