Great job wiring! Love the edits. Snap, and the cable is made! I cant imagine how much time you have invested. Thanks for taking the time to do such a great job and showing us how it all goes together.
Thanks Ross ! I haven't really kept track of how long it took but I spent a while working everything out on paper so the actual physical building didn't take too long.
Each motors can use up to 800mA each (when stalled which normally doesn't happen). And MG90s servos draw around 250mA each but can peak at 700mA if stalled (which shouldn't happen if they are setup properly) . If I remember correctly the arduino draws less than 100 mA . 800*2 + 250*3 + 100 = 2450mA = 2.45 Amps . 2 Amps should work most of the time but in some cases if the turrets moves around a lot and fire at the same time your power supply might not deliver enough current .
Everything is possible but if you want an handheld version with just the firing function it will be easier, quicker and cheaper to just buy a Nerf gun .
@@drohnele3741 .yes you can do it . If you want it handheld you will probably also need to run it using a battery . To make it non-bluetooth you would also need to trigger the firing function using a switch . It's pretty easy to do but you will need to tweak the arduino sketch a little bit .
This thin is so cool I. The most adorable way. I gots to make me one. Hoping there's a kit. Havent dug deep enough yet. There's wasn't a link on part one.
Hi, What a cool project! Please may I ask you why is there rectifier diode on motors? I can imagine that when you need to deliver DC instead AC, but here motors are supplied with DC-DC convertor, right? Does motors run smoother with diode? *sorry for noob question*
No worries, I am really novice when it comes to electronics too! I think this is call a flyback or a snubber diode . My explanation might be a bit wrong and very simplistic but I think the idea is that when you cut the current to a DC motor, because it doesn't stop right away (momentum) it acts like a dynamo and send voltage back into the circuit . The diode is there to stop flowing it back the wrong way .
Is there any way you can tell me were the 330Ω and 680Ω resostors go. I cant read the labelling on the diagram. Thanks awesome project. Almost done with it minus this little bit of info.
Magnificent! Getting all the printed board-holding and modular pieces just right must've taken a long time~ How many prototypes did you go through to get here?
Thanks ! I am not sure, I started with a prototype and modify the parts that needed changes . Some like the legs where right first try but other like the magazine took a few tries as there were a few issues I didn't foresee in CAD .
Thank you so much for that project sharing. I have a question: I bought 12V 2A power suply and gonna use 1x MG90 + 2x MG996. You said min 2.5 A for power supply, but i couldnt found it. Would it be a problem?
The 2.5A figure was calculated for using 3 MG90s . MG996r are power hungry you will need more than 2A . From the tower pro datasheet below you can see each of those servo normally draws between 500mA and 900mA and up to 2500mA if stalled (this shouldn't happen if the turret is setup properly) . If Google is right an MG90s draws around 120-250 mA and up to 750mA if stalled (this shouldn't happen either) . Each motors can draw up to 800 mA . The arduino shouldn't draw much current, let say 50mA . The total current needed should be : 2*900 + 250 + 2*800 + 50 = 3700mA -> 3.7A following the same logic with 3 MG90s you end up drawing : 3*250 + 2*800+50 = 2400mA ->2.4A (just under 2.5A) www.electronicoscaldas.com/datasheet/MG996R_Tower-Pro.pdf
@@Littlefrenchrobot I got it. Thanks for description. So im gonna use MG90s servos and buy 3A power supply (i could only find 12V, guess thats ok. Already we have a buck converter.) I wish you continued success..
I learnt(and keep learning) programming and electronic watching tutorials on TH-cam and a doing lot of googling . I think I would have lost my job if I was an engineer . I have so many failed project under my belt!
@@Littlefrenchrobot Trail and error is absolute normal for a new Invention. Don't think that a professional enginneer are able to calculate every possible failure. Regards from a mechanical engineer, who learned now from your expertise. Well done!

Thanks ! It works, I will release the final video in a week or two . Before that, I still need to polish the code a little bit then make the parts/wiring diagrams/software available on my website so people can build their own .

Will I be able to use a 9V battery for the power supply
Sir what we can use insted of rfp30n06le
OMG cutting the tails off those cable ties would be so satisfying.
This is actually really neat. I have the parts already lying around and everything
Hello i was trying to print the turret but noticed that the right barrel was not in the print files. Would be awesome if you could look in to that!
Hi!! at 10:47, which resister are you using?
How many pins r the dupont connectors?
Hello, for the power supply can it be 9V 2 Amps or does it have to be 2.5 Amps
Each motors can use up to 800mA each (when stalled which normally doesn't happen). And MG90s servos draw around 250mA each but can peak at 700mA if stalled (which shouldn't happen if they are setup properly) . If I remember correctly the arduino draws less than 100 mA .
800*2 + 250*3 + 100 = 2450mA = 2.45 Amps .
2 Amps should work most of the time but in some cases if the turrets moves around a lot and fire at the same time your power supply might not deliver enough current .
@@Littlefrenchrobot thank you so much, keep doing videos like this they are soo cool.

22 gauge
How much power does the Nerf Turret need to work (Batteries)
Have u done this turret using camera?? If yes can you pls upload that
can you give me 3d file for that dart pusher used in servo?
can you make a handheld non bluetooth controlled version only with the fireing function
Everything is possible but if you want an handheld version with just the firing function it will be easier, quicker and cheaper to just buy a Nerf gun .
Little french robot I thought it is possible to just remove the base
