Great job John!!! I found your project looking for a solution to my own ball feeder. I still have two ball falling at the same time and have tried several solutions with small success. I like your spring solution becouse it´s simple and seems to work. Can you tell me how you call that kind of "finger/spring" and/or where did you get it? Thank you!
Thanks for the comment. That finger like thing is a spring door stop. Usually found in hardware stores. I too get double ball drops occasionally but it's so rare I can't be bothered to fix the issue 😬
Hi there, its called a foam board and can sourced from local hardware store. Here is a link to the one I used in the video. www.bunnings.com.au/bastion-1200-x-600-x-30mm-xps-multi-use-foam-board_p0461085
There is an email address in the build guide if you choose to buy it :) If you are not planning to buy it, drop a comment here or on the part 9 video and I will get back to you in couple of days :)
I think I have included links for stl in part 9 video, but haven't posted the parts list. Thats included in the build guide and you can get your copy from patreon - links for that will be in the "part 9" of the video series :)
I understand the purpose of the finger not allowing two balls to fall. What is the purpose of the side bits you stuck on and why the extra raised bits in the middle? What did you do to stop the general jams due to many balls sticking and motor not strong enough? Do the extra bits help that? I cant see how. Only extra bits that balls can jam against.
Thanks for your comment mate, appreciate it. The side wall projections and the raised projection on the disc bed are to aid in preventing the balls from just sliding. It's a bit hard to explain in words but what I noticed was with more balls in the container, the finger projection alone doesn't do a good job with pushing balls off of each other. The side projections help with pushing the ball off of the container walls and into the holes when balls are stuck in a wired way like 2 or 3 of them over the hole. With our the side projections the balls never get knocked over until they hit the finger projection. So they kinda help with a higher success rate of balls in the holes bedore they arrive at the finger projection. The raised projection helps with moving the balls when there are lots of them in the container. The weight of 30 or more tennis balls means the disc would just slip over the balls without that raised projection bit. Not that it won't catch any balls, just that it would be random resulting in infrequent balls getting dropped. I guess the short of it is that with these projections, I noticed a higher rate of balls getting dropped down the hole in a more consistent manner. I'm sure with more testing and different designs this can be done without that but I'm happy with the way it's working now.
The jam was mainly because of two balls falling at the same time and the 2nd balls getting caught between the disc and container When I added the finger projection it went away. As for the projections, I did notice balls getting jammed but the when I smoothed the corners they didn't.
Hi John! Wow, this is looking impressive.....if only I played tennis: I could sign up for UAT 😄 Looking forward to seeing this project through, and then maybe you'll introduce an AI version that examines the player's movements and makes each ball delivery just a little more challenging!
Thanks Tim, UAT is too far down the road, it is still in the design/development phase lol! You could still "blind" test it even if you don't play the sport! Its the best kinda testing to break a system 😁 By the way, a reference to UAT is just brilliant, I guess us IT folks view the world through the IT Lens 👌🏽
Hmm.. I'll keep that in mind. I'm pretty new to this so I'm not sure what MY type motors are. Can you expand a bit or share a link for a similar motor? I'm using this one www.jaycar.com.au/standard-high-power-d-c-motors-10200-rpm/p/YM2776?gad_source=1&gbraid=0AAAAAD0dvLaGLbAB1jLqHS1a39LRgk4bq&gclid=Cj0KCQjwv7O0BhDwARIsAC0sjWONm4Av7aNDAYK659hgKT5wC6Lre8E8AX30A8oGSXYNgO5b-SSkiBgaAkwCEALw_wcB
Hi. Im out to test my machine. Today is so windy . Hope tomorrow. Butchered something up. Still the hardest thing is ball delivery. Im doing something a little different but fear im just making mistakes and will end up following with traditional way. Let me know an email I can send u my video for sharing ideas.
Loved your videos. Well done John!
I will try a hopper with flexible walls too to aid in jamless operation. Either springed box wall system or a material like polyyester.
What I've seen is when the hopper has funnel shaped wall it's easier on the spinning disc.

@@john.alister Thank you. I will try!!
All the best 👍🏽
Hi John!
Great videos! Could you please tell me what is this blue foam-like material you used to adjust the carousel disk?

@@john.alister Thank you!
And for hopper motor i recommend car window motor. Might give a bit more oomph to knock out jams.
Probably right. But I think it will only give you two positions I.e right and left. Which is not bad but a bit limited.
Did you post a parts list or cad file of the stl files by any chance?
I found the Patreon link in the final video. Thanks. What's the best platform to communicate with you with my project?

That we do! keep up the "journey" 👍
Also I found the 775 motors a bit too weak. I recommend the MY type motors for durability as well.
Hmm.. I'll keep that in mind. I'm pretty new to this so I'm not sure what MY type motors are. Can you expand a bit or share a link for a similar motor?

Try this one.. I'll be happy to share my thoughts on your design
