- Update: Check out the latest version of this project here: • AI Case Sorter 7.1 is ...
This is the 7th version of the brass feeder/sorter. Each version I try to improve something that I didn't like about the previous one. This version allows for a much quicker change between cartridges and also as the ability to run much quicker.
The GitHub project, where you can download the Arduino code and 3d print resources as well as the parts list, is located at:
github.com/sjs...
The new models for the Blackbox are in the folder:
github.com/sjs...
The new parts for the sorter portion (bottom half) are at:
github.com/sjs...
The windows software is available after registration at:

My case sorter is now built and running. I started as a complete newbie a month ago. This group of videos induced me to buy a 3d printer (Prusa), buy all the listed parts, buy a couple of books and watch videos on Arduino builds and programing, and start the project. I did have several difficult challenges and issues, but they were mostly of my own making. This is a great design ending with a great result. At full speed it sorts at 74 pieces per minute. Accuracy is about 85-90 percent so far, but improving with machine training including periodic cleanup of saved training images that are subpar. Prints were all with PLA.
Do you know your total cost including the 3d printer?
One of the coolest reloading inventions I've seen, cheers for sharing.
Man, this is an amazing project. I was captivated by DIY case/bullet feeders, but this thing is a whole new level
After watching some of your sorter videos i already have some design upgrades that could benefit this design greatly, i need to get my 3D printers up and running again to make these changes as well as making the fully 3D printed case feeder, after sorting thousands of brass by headstamp by hand this would have been a massive time saver. Can’t wait to show it off.
Can’t wait to see where this goes. You could print a divider that sits above existing bins so it doesn’t take 8 hours each for 8 or 9 bins.
I´ve toyed with the idéa of starting this project on my own, but now that i found your channel I'm definitely trying yours before attempting something on my own. :-) Big thanks and I'll get back to you when I'm further along. :-) Greetings from Sweden.
Will try do build your solution over the Fall/Winter Time 2024 here in Austria and will present my results and the way to get there on the Austria Shooting Channel here on CZcams if OK for you. It's so amazing what you provide here for all of us competitive shooters !!!!! Great!
Thanks! That would be fantastic. If you haven't joined the discord server yet, definitely do that as well
I finally got a 3d printer. I have downloaded a bunch of files for this. Time to start printing in conjunction with 3 other projects.
Genius! I had a similar idea on how to make this. Very impressive man.
Glad you liked it!. Check out the latest video for the updates CS7.1. Cheers!
A thought for the bins with the long print time, make the bin a solid object and print it in vase mode with like a 1.2mm line width.
Thanks for the tip. I have a couple more to print and will give it a try.
Check out a couple of videos on strong vase mode prints. There's a few ways to do it depending on how strong you want them and your available nozzle diameters.
This is really nice. I'm wondering if we could eliminate the internal part change if we had an intake gate. This way we could allow shells into the taller rotating case moving part, one at a time, as needed. Thank you for sharing your project.
Great work! Well Done!
This is awesome!!!
Just keeps getting better and better. I do wonder how long the 3d printed gears will last. Any reason that you could not drive the brass wheel directly?
Mainly space would be an issue. I would have to make the wheel much bigger. Also there is a mechanical advantage on the 2:1 gear ratio. I have only run about 2k rounds through it so far and haven't see any issue but would expect wear to be an issue at some point. This is all more or less a prototype. I do think having the gears made from nylon or a more durable material would be important. There are several shops out there which you can send models to to get them printed in harder materials than a standard cheap FDM can do.
Can I just buy a completed one from you? @@sjseth-builds
Thanks for sharing this, it's been a fun project. I had been working on one a while back with openMV Cam that looked like the rotary dial version you moved on from. I got a bit stuck trying to figure out how to position the brass over the camera without using a piece of glass. Had though about using a microscope slide, but never implemented. Your version seems to have potentially solved that problem.
I do have a few questions , wondering if anyone has experienced an issue where the brass seems to slip down a bit over the camera and get stuck on the edge of the base during the shell plate advance? I think I'll try to chamfer the hole used for viewing on the edge it advances towards, but before I do, wanted to check and see if others had solved in a different way?
Also, if anyone is having problems getting the camera to focus, I had to manually adjust and move the lens out. This allowed it to focus on closer items.
One additional thing, if the spots where the spring connected to the tenson cam and the classifier base had a hook I think it would be a quick improvement.
So the problem you mentioned has been solved in the latest version (which I haven't released yet) but it involved raising the feed side by 2mm and also cutting a groove in the tension cam in which an o-ring sits. The rubber gives better traction. You can also just super glue a bit of rubber band on the contact face of the tension cam as that seems to work for others as well.
Very nice! I wish I had a printer!
Great👍👍👍👍👍❤
I need this adapted for sorting rimfire for swaging!
you need to design something that can sort by caliber and then use this to sort by headstamp would be fantastic
Theres already a stacked sorter system that will do 80% of that through a quick shake
@@itsasinine3337 point me in that direction please
looks great
DAMMMM!!!!!
Such great ingenuity! Thank you for all your hard work and dedication for this! Is it possible to detect crimped primers and kick them in a separate bucket for swaging? I fired up the printer and started the first print tonight, along with ordered the parts list off amazon!
Check out the video I just posted on primer detection! I don't know if detecting crimp will be possible but definitely something worth trying!
That is awesome
Wow... now if you could design a weight sorter, I think you would have people lining up to make orders. I am sure it can be done since there is already powder auto ticklers that read the scale such as FX-120i and all you need is a delivery mechanism that would drop, grab it back and deposit in the designated by X,Y bin - bingo!
do 380 brass jam the disk?
Howdy mate,
Thought you probably want to know, the links to the amazing version above above does not work (second and third links)
Still absolutely amazed at the fantastic prototypes you put together, totally mindblowing!!! :))
Thanks brother! I have updated those links and they should be working now. We have been reorganizing the files in the projects so pardon the mess!
I have everything working and there is one issue that Im wondering if you have experienced as well. Every once and a while a 9mm case will fall "tilted" and doesn't drop straight into the cartridge spool. When this happens, the sorter jams and will grind on the gears. The only way I can resolve this issue is to power off the motor controllers, correct the tilted case and move on. I have tried adding o-rings to the drop tube to keep it from moving and even adjusted my homing offset to get the drop hole perfectly underneath the tube. No matter what I do I have maybe one out of 100 cases that will do this. Not a huge deal but definitely requires me to sit and stare at the machine when I run it through a sorting cycle. Have you ran across this? Would it be possible to have the stepper motor back up by 1 or 2 steps right before it rotates clockwise? This "jolt" should correct the tilted case. Another suggestion is to have the machine stop the sorting process after X amount of seconds not getting a focused case picture (similar to the stop function after getting several "blank" pictures) . Hope this makes sense. Thanks!
Yeah, I have encountered this from time to time and there are some fixes. If you don't mind, please email me and we can troubleshoot it further. My email is in the channel info (you need to use a computer as it doesn't show on mobile devices)
Love the CS7 design, Can you add the ability to sort 308 and an IndexWheel ? Would love to separate military from commercial brass.
Yeah, I was just about to sort a big batch of 308 myself. Will be adding the 308 wheel this week hopefully
Smart people are so amazing. id love to have a 3D printer. Really need some K31 stripper clips. Found a file to make them. Just cant do it myself.
Check out CraftCloud (craftcloud3d.com/upload). If you have the model already, they will print it at a price.
Great idea and it looks really well implemented. Parts have already been ordered and the printing begins. I would have small ideas for improvement, also with regard to the reflections. How can you best contact you?
Awesome! Looking forward to seeing what you come up with
Nevermind. I see how the different versions are nested now on the github. Duh.
What are the support pole sizes, either in or mm? Thanks. I do not have a Dillon case feeder so I'm making my own. just wondering about the diameter.
It is a 1 inch diameter pole.
been following and Im in the process of assembling the parts. Finally a project that will force me to get a 3D printer. 😁. My one question is about the windows software. can it be trained to recognize the difference between small and large primers? i.e 45 ACP SP/LP or 10mm SP/LP
Yes, it can be trained to do that. In fact, it would be a good demo I think. Maybe I will try to put one together if I can find some small primer brass in my buckets...
@@sjseth-builds good news. nothing like being in the groove loading 45s and everything comes to a halt when you try to stick a large primer in a small primer pocket.
This is so awesome
The camera seems to be unobtanium in Canada. Any issues replacing it with a higher resolution camera as long as the FOV is the same?
I think as long as the sizes and fov/focal length was the same, it should work. The camera is also avaliable from Ali Express here: m.aliexpress.us/item/2255800428160152.html?spm=a2g0o.productlist.0.0.5f707621prYXZz&algo_pvid=d1db212b-8be3-41c3-bbe3-e88c7cc93bad&algo_exp_id=d1db212b-8be3-41c3-bbe3-e88c7cc93bad-59&pdp_ext_f=%7B%22sku_id%22%3A%2210000004016284977%22%7D&pdp_npi=2%40dis%21NOK%21263.94%21250.77%21%21%2192.79%21%21%402101e9d316664697050524419e75a3%2110000004016284977%21sea&curPageLogUid=ZHqutjEPQrzU&gatewayAdapt=gloPc2usaMsite4itemAdapt&_randl_shipto=US
Ok, I found another one on Amazon which looks to be the same thing and I stock. Here is the link, make sure to go for the 100 degree version. 0.3MP High fps USB Camera Module 1/4” CMOS OV7725 Sensor with 100 Degree M7 Lens,Support 640X480@60fps,UVC Compliant,Support Most OS,Super Mini 32X32/26X26mm USB with Camera,High Speed USB2.0 Webcam a.co/d/386nwkx
@@sjseth-builds Amazing, thanks for the help!
I'm assuming you printed the case wheel with supports?
Yes, I just used standard supports in Cura. For the main base I used tree support with 80 degree support threshold. This prevents the supports from mixing in the threaded part
Can the software be modified to detect berdan primers by the primer diameter?
I don't believe there is any detectable difference in size for berdan primers so probably not possible based on that, but the berdan primed brass usually has an associated headstamp that it could sort by.
I did think of headstamps but some are both types of primer. Large rifle berdan has a larger diameter cthan boxer, etc…. Is it possible to use the camera to look down the neck (invert the case) to look for one flash hole in the Center?
I don't think the machine could do this as it stands today. You would have to be able to focus the camera and the light to look into the cases and then alignment would be an issue as well
I mean, theoretically it's possible with this machine but would take some tinkering
Is there a folder of all the STLs
Check out the video description for that info. The latest version of this project is here: czcams.com/video/s7dy0odA44U/video.htmlsi=l41b2ENoDnvgETd_
What is the name of the microswitch, it feels like 1837636 different and which pins is it connected to?
Not sure what model number but here is the link where I ordered them: www.amazon.com/gp/product/B07PCN6T6F
Also pretty sure this is exactly the same thing without the wires plugs and control board. www.amazon.com/Cylewet-25Pcs-Switch-Arduino-CYT1073/dp/B073TYWX86
Re: Pins, it connects to 5v, grnd and pin7 if you are using this arduino sketch github.com/sjseth/AI-Case-Sorter/blob/main/Arduino/case_sorter_CS7/ of course you can always update the arduino code and connect it wherever you prefer.
Might you ever sell a ready to assemble kit?
Currently I have no plans at this point to produce or sell them. I have thought about the kit idea but at this point, not really read to do anything like that. Thanks for your interest!
This looks like a project I’d be interested in funding for production. Care to reach out?
My email address is available in the channel info page when accessed from a computer.
Hey I’d love to talk to you about this project. I am in the market for a commercial application to sort .45 by primer size
The software can definitely do that and is very flexible in that, if you have a better machine design (like something made out of metal), it can communicate to it over serial bus. My contact information is in the channel info but you have to be on a computer (not phone) to access it
I've been working on a setup to sort by primer size that would work in a commercial application. I've uploaded a couple videos of the progress. Its an automated dillon 750 and I've replaced the primer inserting with a go/no-go gauge for the primer pocket hole. Station 1 decaps and sizes, station 2 probes the primer pocket. Then the arduino keeps track of what brass is in what station and it sorts them with a servo and flipper at the output chute. Its not smart enough to sort by headstamp like this project.
I've been running mine at 1500/hr. It will crank up to 1800/hr, but I've kinda been scared to run it that fast and start breaking my little switches or outrun the servo flapper.
