Arduino Stepper & Servo Sorting Machine! Video on Design, Functionality and Arduino Code!

- This is one of those projects that ties in everything I love: machining, prototyping, Arduino, robotics, sensors, automation and more. It was a rapid prototype and test machine to automatically sort spent brass cases by diameter (a.k.a. caliber) and dispense into appropriate bins. This is the long/detailed video. The short video is at: • Arduino Stepper & Serv... 5 Reasons to Use a Fixture Plate on Your CNC Machine: bit.ly/3sNA4uH
You're channel is awesome! I started as a hobby programmer, and then expanded into doing scientific process controlling for my university. As a biology undergrad, I had to learn a ton of engineering, of the kind that you just can't take a class for, so its really nice to have your videos. Its allowed me to start inching into doing some basic machining, and take on cooler more advanced projects!
Very complete and intuitive! The next natural question: If you are tearing it apart now to use parts on other projects, how are you sorting your brass? LOL!
What a great setup. I played with an analogue variant: two counter rotating rollers diverging so that the case is rolled progressivley down the rollers until it falls through. I like your design better though....you could even have added a load cell and weighed the cases, further sorting them or perhaps even with an exception bin to catch the dreaded '9in40' and '40in45' combos.
*Hi, where do you get all those accurate metal parts for your inventions?

Great project! But where did you get those gears connecting your stepper motor to your sorting machine?
Real Good, I am a bit surprised that you did not show a no-go or out of range sort bin. Or an air ejection when cannot open wide enough.
Thanks! I just used this to create a pneumatic controlled assembly press for a product I produce!
You should try the parallex 2x16 serial lcd with back light. It only uses one pin instead of two
How do you keep the 9mm from getting in the 45cal case
Wouldn't be easy if you set the sensing by completing the circuit?
A Rod moving by the stepper motor till it touch the round shell,
the Micro second that it touch the metal it will read how many steps even before the stepper have a chance to miss a step or for the gravity that pull the shell down.
then the laser would just read for jamming alert purpose.
what do you think?
shells are bare metal, even for plastic you can use a touching switch just kuje the ones used in CD/DVD optical readers.
the laser is surely a plus if you count a gravel :D, hahahaaa
It's the gravity VS time,
and for that sake stepper will be too slow if you're checking thousands of bullets, since youre a pro making metal and have CNC you can build one like this motor which I took it out from an old Inkjet printer

I'm thinking of using it in Arduino project somehow.
For all purposes including gravel, a V-shape and a fine screw that move one of these V jaws like a vice and that laser or IR for less power maybe...
will be another version, yours inspire me to use that motor for a usefull thing :)
Im just a newbie with micro-controllers but can survive the free codes use.
Thanks for your reply :)
excuse me i'm talking too much ^^
Awesome project! I am currently working on a senior design project through NDSU, and my group and I are trying to sort brass mechanically using an X-Y Table and linear potentiometers to distinguish between calibers. Due to the overlap in dimension tolerances we are trying to gather base diameter, height, and neck diameter (on necked casings) to separate each caliber. I have been trying to find your video on how you put the casings into the ammo boxes. I am trying to find tutorials on programming a basic x,y table using an arduino dev board. Unfortunately, my teammates and I have no prior experience programming....and time isn't on our side haha. Can you please help me find what I am looking for?
looool when ur machine is built like a gatling you damn sure do love guns!
VERY cool. I'll be starting shortly on a version which will steal heavily from your design. Brilliant.
That's cool I need one for drill sorting.
Thanks for posting this excellent video John. While watching, I thought of an up grade for case length sorting using a laser distance reference. Keep up the good work:>)
What kinds of brass sorting would be handy with machine vision? I am sorting coins by date and it seems that the same system can do tough brass sorting jobs.
+Paul Krush Hello Paul, are you able to read circle text with the OCR software you are using? I guess, if you are using OCR?
+Nolan Michaelson I am using a Deep Learning tool called Caffe. You can train it using images of the casings. It's not reading the text per say, but training on it. So you could also train on clean vs tranished. Straight vs dented. Fired vs not Fired. Round Types. A Round vs a Rock. And so on, as long as there is a difference in the image. Well and given that you can handle the part and automate taking the image. If something is untrained you are going to know that too because the confidence will be low.
Since I made that comment I have designed new very low cost laser cut conveyors that should handle the brass.
+Paul Krush Also I would have to say it's a lot work at this point.
ever seen how a camdex sorter works? just a pair of slip rolls on a low angle to create a v. you just put the chutes wherever the cases you want fall out of.
Oh dont get me wrong. i like this idea. the camdex is cool. but its huuugggeee and crazy expensive. This reminded me of the camdex in a way..Just gotta get that collator hammered out. making a multi caliber carousel has got to be a small nightmare!
still waiting for someone to do arduino setup for driving a leadscrew on a mini lathe to access feed/ and screwcutting including metric...but I do not know enough if you can setup arduino system to accept commands?
John NYCCNC
I was hoping that i was the first to think of it darn oh well..but if you can remember or if one of your viewers remembers please let me know I would love to mate something like this to my little lathe..
Do you still have the code for this posted anywhere?
Excellent video, great project!
Thanks for sharing!
This is awesome stuff!!!
Great post and tutorial! Thanks.
Where can I find the code?
Great project!!!
how have you not did a DIY 3D printer yet?!?!?!?
because if you can make a CNC i think that you would have a lot of fun making a 3d printer
that would be cool! ... and extremely challenging lol.
SIMPLY AMAZING!!! :-)
love your videos mate . you da man
wow
excellent work! Thanks allot for sharing!
