- I've made a fully automatic, heat-seeking nerf sentry turret to defend my poor meatballs from being ravaged. Will the turret succeed in driving away from the freezer which it defends? Or will an eighth inch thick piece of see-through material spell its doom?
There were so many bugs in this stupid project its crazy. Turns out its actually kinda hard to detect and track a human with an 8x8 grid-eye thermal camera... who'da thunk?
Thanks for watching and comment down below what you'd like to see!

Literally had a mind of its own lmao. The poor corner of the room catching literal strays
Its funny in retrospect but it was so infuriating at the time lool
It can see the same demons that like to hide in the corner of rooms that cats can see, fascinating
Turns out it was working the whole time it was just tracking the demons in your house
Thanks for that
@@currentconceptthe only one they fear is the Adventure Force V-Twin mounted on the ceiling
And It shoots the whole Dart! Its 60% more Dart per Dart!
CAVE IS THAT YOU???
I dare you to get a nerf moab by gattling tommy and use it for your sentry gun
I'm writing this before the end of the video before I forget - the heat camera. Look up "Installing Workshop AC and Sealing our Garage Door" by Evan and Katelyn where they used a thermal camera to show up how garage doors leak heat/cool.
ooooh I'll have to check that out. That sounds like it might've solved all my problems lol
Awesome video and the nerf sentry is great, plus your wife came in clutch with blocking out the heat for the gun. I had a few comments for some problems you had. Firstly, for the keyed shafts, look at splined shafts instead for power transmission. They're used all over a car from the engine power output to the steering column. They're just an invloute gear profile with a 30° pressure angle.
Secondly, the lazy susan bearing is designed to be used in compression not in tension. You can see it not working around 5:04. The ball bearings in between the 2 plates should move at a different speed than either plate (half the speed of the moving side) but you can see that they move with the bottom plate. You'd be better off changing how you hang it by finding a way to compress the bearing. You can also look into taper-roller bearings, where you have the gun mounted to the male cone with the cone facing downward and the female cone on the stationary mount. You should be able to 3D print one that will be suitable for what you are doing.
Thanks for watching! The spline idea is great and I will absolutely be using that moving forward. Thats good to know about the turntables.. thank you for all this mechanical insight! Its the area I lack the most - sometimes I dont even know what to Google when looking for a solution. I appreciate this comment
You're going to get the 3 letter agencies on you if you keep this up
lets hope
Always cool to see people automate Nerf sentries! There was another video that made an automated sentry (I think it was for a Valorant sentry replica?) that used an AI camera with human recognition. I wonder if you could combine those input methods? Also, if you're looking for high power automatable blasters, I think Jupiters (or is it Junos?) are great for using Rival rounds and having extreme ammo capacity via a proton pack, and if you want power as well as speed you might want to look into HPA or AEBs. HPA would actually be really good for a stationary system, because you could have a huge pressure tank and even an air pressurizer right there!
I would like to revisit this some day and make it much more accurate at longer distances. These are great suggestions thank you
@@currentconcept ah, if you want distance as well as accuracy you may need some of the higher end half-length darts, like Workers! They tend to be heavier, and since they have ribbing they don't encounter as much friction going down a barrel, also being short they're much less prone to fishtailing. That, or some heavier Rival rounds. Add some rifling too maybe? SCAR, BCAR, I don't know admittedly! There's a couple Nerf resources for optimizing the bejeezus out of perfectly normal blasters, I'm sure in a regular research phase for your next revision you'll find some great info! Happy making!
There are the TF2 lvl 1 sentry and Portal turret that WETA Workshop made for Valve, which use human recognition too! (oh man, those are older than I remember. The video on the TF2 Sentry is 13 years old and the Portal one is 12)
6:25 random aiming was terrifying and hilarious
It would be interesting to put a flamethrower
u could try usying YOLO to track peoples
Thats that neural net isn't it?
@@currentconcept yes
That was a lot of fun to watch! Super cool project! Now, I can't stop thinking about "Ednas" security guns from The Incredibles. 🙂Dangling from the cieling, They would blast you if you didn't have the password and they were also "Smart enough" to recognize the other occupant. Would it be possible to "see" what your turetts thermal camera sees? I used to have a handheld thermal camera with a nice resolution screen. If you couldn't see what the camera sees, how did you set up the "Exclusion Zone"? OOOO!! I just remembered something!! Metal surfaces are like MIRRORS to Thermal cameras!! It is a wild effect to see in person... Yes the garage door is a massive thermal loss but it is also is kind of like a mirror...(I conceed that the heat from the sun beats out any reflected heat it could detect) ... is your refridgerator door metal? That's just a mirror on a swivel to a thermal image. 😀The covers to the electrical panels look like The Magic Mirror from Snow White. Its darn impressive how far/deep that "reflection" can see.. I swear it looks just like a mirror but in a crazy color scheme hahaha. Thaks for the awesome video!!
Yeah thermal cameras are super cool and weird lol. I set up the "exclusion zone" by counting the motor steps. If the camera detected me while the motor was in a certain range, it knew that I was trying to steal a meatball. Also its possible for me to see what the thermal camera was seeing, I'd need to take the pixels data and put it in a grid and colorize it
“I'm holding all the cards,
and guess what?
*_THEYRE ALL FULL HOUSES!_*
never played cards, meaning to learn…”
i love how menacing it sounds when you creep up on the freezer. awesome job!
thanks! really makes you think twice about wanting a meatball y'know
"Sentry Goin up"
😂 great video. I loved the humor and insanity of this project
Thank you!
Cool, now make the gun fire meatballs…
I'd just eat them as they came out
Nice! When it revs up before firing you get say 500ms to think "why am I doing this again?"
Its actually "zone" based, so there's a zone in front of the freezer where it'll spin up to warn you you're getting too close. But once you step closer to the freezer, you get lit up
“Sentry goin’ up!”
-**TF2 Engineer**
can this be used with a real gun?
Yes but only once
Not unless you want the ATF to come shoot your dog. (the ATF would consider this a machine gun)
That medics a bloody- sentry! OOOOOHAHAHAAA
Best alarm clock ever!
Wow this comment is unbelievably prophetic... you'll see why in a month or so
Gattling gun Nerf sentry? Awesome. Awesome to the max.
How are you so funny? It's so unexpected- "It started out pretty well with me forgeting to plug in" I'm dying rn
You could also try to mount a rival persies (sorry I can’t spell the name right)
this chanel is criminally underrated despite how good the video is.
also one idea: give it a laser pointer, a larger belt and paint it black to make it more intimidating.
Flashbacks to those hallways in half life
Next time make a heat-guided missle!
hmmmmmmm...
1:58 when the Concept is Currenting
Lmao true
tf2 engineer behaivor
It's the turret from Pressure!
team fortress 2 yay
Guy lives in gm_construct
Cool
thanks
You need a larger ammo belt, or maybe add some of those little firework popits
fireworks would be hilarious if they didnt have the possibility of catching the house on fire
@@currentconcept im talking about the little ones that you throw on the ground and they make a pop noise
Erecting a sentry right here.
8:42 BRO COMMITED SUISIDE
Sentry goin’ up
The gun has demons 6:16
i have two of that nerf gun.
Instead of using heatseeking, you should use AI face recognition and tracking. Because the stuff you’re trying to do is getting easier and easier with the years to come with the help of AI 🤖
all hail our robot overlords
Now do Level 2..
Oh if only the bosses in Japan could see how that sensor has been used!!
the amount of paperwork we had to do to sell those when we first had them was mental... and guess what the No1 application was that was a sure fire rejection from the factory... yep heat seeking weaponry!😅😮💨
Lol thats awesome
YOU BIG BACK
i have a bigger one
Engineer gaming
How do you not have more subs?! This stuff is amazing! Keep up the good work
thank you! Trust me I've got a lot more coming
i love that it spins up first giving you a warning, then shoots if you get closer! earned my sub
thanks!
Brilliant :)
Don't garage door sensors use infrared? Is that what the sentry sensor finds so attractive?
No infrared is line of sight only. If the receiver can't see the light, it can't do what its supposed to. Garage door openers use radio frequency stuff usually
Bruh why u got a trigger servo if the trigger is just a button? Just take the whole button out and have it just put a direct input in
I coulda done a transistor but I'd rather struggle with a servo
Damn
It seems you forgot about the whole "things other than humans can be hot" thing. :P
Thats impossible
I thought as soon as you called it a stupid piece of trash that it would start working and shoot you
lol, that woulda been great
it would be crazy if these were mass produced and sold to the public for home defense
👀
I just realized that's the exact need machine gun I have lol
I know something you can do with it
Cool project! Wouldve liked to see how much better the performance wouldve been if you could pair a cheap webcam with it and use some basic ai recognition software to denote whats a human or not, or maybe a higher resolution thermal camera if the funds allowed it. Would also like to see how well it wouldve worked if you were hiding behind a glass panel you happened to be carrying ;)
Thanks! The thermal camera was $30, and I wish I had more funds for a higher quality one but that's not in the budget right now. I'm pretty sure the glass panel would have the same outcome as the plexiglass... right?
@@currentconcept Being similarily transparent in the visible range does not necessarily mean being similarly transparent to IR.
I used the same camera for a animatronic that tracked folks as they walked by. Also had the “what are you looking at” problem when using the warmest pixel method. Worked fine in the spare room then stared off to the distance outside. Turns out the street stayed hot even into the evening, as did parts of the house across the street. I solved this problem by using what pixel changed the most method and that solved my problem in cluttered environments. I discuss this in my video here : ua-cam.com/video/syvH8i-V0Zk/v-deo.htmlsi=hvrTXINzlk9ql8nR
it's kinda cute tbh
Ur kinda cute tbh
The bike is black rubber so it’s hotter than the surroundings.
“Ain’t that a cute little gun?”
Just use a regular camera
well then it wouldn't be heat seeking
@@currentconcept
Maybe you could make it "seat" seeking instead, but the bruises might be harder to explain ;) .
2:34 am I just that hot?
you know it Jim
