Face-Tracking Nerf Turret V2 - Part 1
Vložit

- In this video, I go over the firing mechanism for my second nerf turret. Using the base of the first turret and an entirely different top, I was able to significantly increase dart capacity and firing speed.
The original program remains mostly untouched and still uses an OpenMV camera for the eyes and an Arduino Mega for the brains. The newly designed firing mechanism is much more complicated than the Nerf Jolt used on V1. It is controlled by a Raspberry Pi Pico microcontroller.
The next video(s) in this series will focus on cleaning up the mechanical structure as well as the program. Stay tuned.

idk how you only have 273 subscribers , but your channel is better than a lot of the big name engineering channels on youtube. I hope you get the larger audience you deserve.
probably because he only has 2 videos so far, but I would be surprised if he doesn't grow a lot over the next few releases
Thanks, I appreciate that!
I'm very interested to see the improvements made to the target tracking. I love the explanations for how things were put together coupled with seeing individual parts in action. This thing is sweet!
Thanks! I'm going to make the camera control the servos instead of a separate Arduino. I think the constant communication between the camera and Arduino is really slowing the program down.
Can’t wait for the view count to catch up to the quality of your videos. This is incredible.
Can't wait for next vid!
Finally I'll be able to get more info on intricacies of this beautiful piece of engineering. I'll try to swap NERF blaster for my antique blunderbuss to blow up my face :DD
A truly great way to merge new technology with old I say.
For the Flywheels having a concave face helps a lot. They get more contact surface to get up to speed and they won't get tore up as fast.
I like the neatness of the solutions with little bumps to show when the magazine is in position.
Sure, there are quicker ways but the design feels so neat!
Looking forward to seeing more from you.
Here before this channel gets big 🤙🤟
This is a very impressive project, and the video is very entertaining too! You have a bright future
Really nice video! I really like your step by step detailed explanations of everything, looking forward to the next part. I'm also working on a similar project, trying to fire erasers from a turret to hit my hand so I can catch it and it's nice to see someone else facing similar issues.
Well described and the issues encountered fully discussed. I'm not likely to build one, but feel that I am so much better informed about the whole process. Thank you. I know a young lad who would just love to build something like that. A dreamer like myself.
You have some really interesting project bits here. Like many others, I'm interested in how you are doing object tracking. I could use some ideas there for projects of my own.
One suggestion on video production: Your audio levels are all over the place, to the point that it makes the video difficult to watch, or at least to listen to. The interstitial music is a good 10 dB louder than your voice, though you voice volume about doubles from about the 14 minute to 17 minute marks, then fades back to the low level. The interstitial music is so loud that I need to almost completely mute the audio to preserve my ears. Unfortunately your voice is then so low that I miss the first 3 or 4 words in the next section before I can get the volume back up to where I can hear you.
As a general rule, background music under speech should be about 10 dB down from the voice average level, and interstitial music should be 6 to 10 dB down below the average voice level. Remember, it is what you are saying that is the important thing to listen to, not the background or interstitial music.
I hope to see more videos from you in the future!
Thanks for the detailed feedback, I'll definitely use it for the next video.
I’m glad I stumbled upon you on the tube. I hope you get bigger man. Keep up the great work!!!
Thanks I appreciate it!
this is just brilliant, good job
Bro amazing editing style and incredible projects for sure make more of these videos.. U will be very popular for sure
Thanks I appreciate that! Currently working on the next video and I'm hoping to finish it in the next couple of weeks.
@@pb.projectbox uk no need to put complete project videos u can make parts like the process
This is great, more subs have to be coming soon!
I feel like if Mac from It’s Always Sunny learned to code, this is what you’d get 🤣
Cool project and great video 😎🍻 going to check out more of what you’ve done for sure
Sentry right up ahead!
hey, like the build. very cool. Have a suggestion for your videos; the difference in volume between you talking and the text prompts is massive, one moment I'm turning my headphones up to listen to you, the next I'm blowing my ear drums out when you get to the next section. recommend some gain normalisation. overall very cool though.
I really like what you're doing, especially how you show the methods you have tried or considered. BUT, as a viewer, I have a request. Please, please, normalize the audio levels across the whole video. When I crank up the volume so I can understand you, I then get blasted by the music in the segues. Also, while you're at it, get a mic, it will improve your quality massively. Can be lavalier mic, doesn't have to be expensive, personally recommend second-hand. Looking forward to your next video! 😊
Thanks for the input, I'll be sure to pay more attention to the audio levels for my next video. I actually did use a mic for this but I was wildly inconsistent on how I used it. Obviously audio isn't my greatest strength lol
Also maybe make the cuts a little shorter when this music plays. Really enjoying the videos. Great work. Looking forward to part 2!
Great advice, the music was really loud
Excellent video, well thought out and detailed, as you progressed through each step of the build. I'm sure you thought about this, but what if the flywheels started spinning up as the dart cartridge started to traverse to "chamber" its next round? At that point it should already be at full speed ready to launch the next dart. However, as you solved the "difference" in speed between the two flywheels, this may no longer be an issue? Keep up the great work, looking forward to Part 2.
Great video! You should try to find an old junk surveyors theodolite to use as a turret. It would be super smooth and stable and probably require very little modification.
That's an interesting idea! Might have to look into it when I start working on increasing accuracy
Super cool!! Have you considered using a spring loaded magazine for the darts? It's more space efficient, especially with double stack magazines.
Very briefly, but I wanted to be able to quickly reload all four darts at once. I'll be expanding on that in my next video.
Epic 😎🤓
You also built worlds slowest nerf magazine! 😃
Sure did! I think it makes up for it in style points, though
I made a Nerf turret too! I found that the TensorFlow face detection (FOMO I think?) example for the H7 is much more reliable compared to the Haar Cascade example. Have you tried that?
I haven't, but it sounds like I should give it a shot. Where'd you find the TensorFlow face detection example? All I see in the IDE is the image classification and object detection.
Why you wouldn’t just use high capacity existing dart magazines is beyond me ^^… also use half length darts as they are more accurate. I can recommend worked Talon Magazines or in this case a 29 round Tachi Mag by Out of Darts.
Why engineer it when you can over engineer it 😉 Hope you can get it to work! Subscribed 👍🏼
Great video! Sub'd
Did you consider using Nerf Stryfe auto loading style?
I only briefly considered using existing Nerf magazines, but I thought it would be more fun to come up with something new. I also am planning a self-loading mechanism that will quickly load all the darts at once, which would be tricky to do with a Nerf magazine. I may reconsider due to how quickly those things can fire, though.
great video and project but please work on you're sound levelling the music is super loud and your voice is quite
Magazine? Isn't that a clip?
can you give files
anyway project is damn cool
I don't have plans on releasing the files yet. If enough people are interested I'll probably put them out.
I wonder if you could have used one ESC to both motors to synchronize their speed.
That could definitely work. Once I dig into improving the electronics and program I may try that.
Been there tried that doesn't work, you start introducing sync issues and you need a much larger ESC to cope with doubling the load.
@@Stambo59 don't they synchronously spin at a fixed speed, I know they struggle to start but they could just be left spinning?
Also double the size?
@@dfgaJK Trying to use one ESC to control both motors would require a higher current ESC.
Simple math really, if each motor draws 15amps peak that is a total of 30amps.
Allowing for a little leeway as you don't want to run an ESC continuously at peak that would require a 40amp ESC. For some reason you also get reduced top speed and power.
Point is moot really as trying to run 2 motors off 1 ESC is generally not a good idea.
Why don't the motors run at the same time and speed if they are receiving the same signal? Is it due to the physical tolerances?
Impressive, but please level the next time your voice and the music to the same level.
Thanks for the input! I'll see if I can fix it in CZcams's editor and I'll definitely spend some more time on it in the future.
@@pb.projectbox If you are using Resolve for video editing it should have some pretty good tools for audio management as well as video. I'd suggest digging there, and skip any CZcams editing.
Part of you editing pipeline is interlacing your footage. 1080i rather than 1080p. This shows up as lines in your videos and doesn't reflect well on the time and effort you put into them.
Thanks for the input. The beginning is probably the worst of it and I'm guessing it has to do with the camera I used to record it. Still trying to get the hang of making videos haha
@@pb.projectbox I looked at your last video again and it doesn't show the same so I don't think it's the camera. Do you use premiere pro?
It's definitely not your camera. I just checked and its in the text as well .
@@dfgaJK I used Pinnacle Studio for my first video and switched to Davinci Resolve for this one
@@pb.projectbox I was wrong it is not an interlacing problem, its a 2:3 pull-down problem. You need to make sure your timline frame rate matches your cameras recording frame rate (30fps or 60fps for web content).
69th comment wooo
I wanted to bs on this project since I’m making something similar. You get my insta message?
Yep! Just sent you a message.
