I also stick sandpaper on wheels to get the grip. But might change to a rubber band over the wheel created from a large tyre. Especially if the sandpaper kills the fluff too fast
Yeah sandpaper might do that to the balls. A cycle tube might work. But watch out for the wheel balance issue. Check out my latest video for my approach on the wheel.
Hey John, I have been working on a ball machine design of my own for the last few months and discovered your videos just a couple days ago. There don't seem to be many videos covering this topic so it was fun to see your approach to things. I'm a mechanical engineer and I design/build/program industrial automation machines. I'm used to high end, expensive industrial automation components paid for by my company. Funding this myself has brought out my inner cheapskate and has driven me to get out of my comfort zone and research components in the hobby space. I haven't really touched an arduino for 8+ years and so the little I did learn programming an arduino is rusty at best. I appreciate you sharing your code and will very likely use a good portion of it. There are a couple of things I could suggest to help with your mechanical design to overcome the balance/vibration issues you experienced. Let me know if you are interested and I'll be happy to share. My plan is to eventually document my project like you have (with way lower video quality and flow), but I am not far enough along to start that yet as I'm sure you know that is a huge undertaking in itself. Again, thanks for the well presented project and let me know if you'd like to chat!
Hey Clint, love your comment. And I am so excited to see the internet bringing random folks like us from different corners of the world together, its just amazing. I would love to hear your thoughts on the mechanical design and I am sure some your and my viewers will also find that very useful. And I might be able to help you with coding related queries if you have any, that is! Its no joke, this project. It is a constant tradeoff between weight and portability and cost. I want to keep it as light as possible but after the recent attempt at building the launcher module, I am beginning to think that I might have to ditch the plywood and screw idea in favour of aluminium or steel frames. But you sound like you've got lots of experience in this area so it would be great to hear what you have to say :) Here is my email (if you prefer) - grove_beech0g@icloud.com, we can go from there. Cheers
@@john.alister Hi Clint and John, the story of Clint is exactly as mine. I am also a mechanical eng and I'm starting the design of my machine with a colleague. It would be great to share the knowledge and work together on this. May I join you guys on the discussion? If so, I will send an email too.
Hey everyone - here is the link to the code and flow chart drive.google.com/drive/folders/1BluocPSngjgFQCiUjjyVApOmeu2kkyHe?usp=drive_link Let me know if you have any questions - I'll be happy to assist
I need to do more with a system to stop the double. Ball drop. Your springy thing seems ok. Ive tried a few options but seems balls still want to collect in a way to get stuck together. But im doing an odd thing. My hopper is not parrallel to earth Its slanted and only one hole. Might have to change over to the usual flat 4 hole way
Hi, nice to see your comment! Yeah the ball hopper can be a bit dodgy. Keep at it mate. You'll solve it eventually. Trial and error is the best thing about a diy project like this. Can be frustrating at times but a bit of break or an overnight sleep can do wonders to solve problems.
Hi John Alister! I design fixture for welding automation. I want to make a machine for pickleball. Just lucky for find out your video. Let do together!
Hey guys. I am also building my own machine . I have sourced the motor and wheel from china but really want to be able to produce my own here in South Africa.
Oh nice, it'll be great if you can share some details on the motor and wheels for the rest of the community. I got mine from a name brand as my hunt for those on the Chinese websites weren't successful. I discuss this in my recent video. All the best 👍🏽

Happy to collaborate mate. There's power in numbers 💪🏽.
It's a bit late here 😴. I'll pick this thread up in the morning. 👍🏽
@@john.alister excellent! I will put together an email we can go from there.!

Thanks mate, glad you stopped by 👍🏽
I'm having second look at my design and should soon be able share an update. Stay tuned 👍🏽

Hey, John. I have a 3D printer I could print parts for you.
Thanks for that Chris, I’ll probably end up ordering it online if or when I need 3d printed parts.
