I Made A Heat-Seeking Nerf Sentry Gun

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!

Hey y'all,

a few people have asked for the files for the printed parts. I've made this GitHub repo with the stl files for all the printed parts in the vid. In the repo I've also included a parts list you should get if you want to build this yourself. I am not affiliated with any of the parts I listed - its just the ones I used.

Also, I'm not going to be making a how-to on this thing. If you've got the parts and the will to do it, I believe in you and your ability to problem solve. That's what building things is all about anyway, right?

Glad you guys are enjoying the vid, and thanks for watching!

Imagine the tf2 engineer building a sentry and having to fix a programming error mid battle.

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

And It shoots the whole Dart! Its 60% more Dart per Dart!

“Hey look buddy, I'm an engineer. That means I solve problems, not problems like "What is beauty?" Because that would fall within the purview of your conundrums of philosophy. I solve practical problems, for instance: how am I going to stop some mean mother Hubbard from getting to the freezer and grab those sweet, sweet meatballs? The answer, use a gun, and if that don't work... Use more gun. Take for instance, this heavy caliber wall mounted, heat seeking lil' old number designed by me, built by me, and you best hope... Not pointed at you.” - Engineer

i love that it spins up first giving you a warning, then shoots if you get closer! earned my sub

[nickholton]

Literally had a mind of its own lmao. The poor corner of the room catching literal strays

[Niceninjapro]

Cool, now make the gun fire meatballs…

[chrisgenovese]

i love how menacing it sounds when you creep up on the freezer. awesome job!

Now we need a heat seeking BB Gatling gun

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.

[ethanebang]

I dare you to get a nerf moab by gattling tommy and use it for your sentry gun

You should replace the nerf gun with an airsoft minigun, they fire faster, harder, and pack a punch.
