First of all your project is very nice, in fact I think nicer than other ones that I've seen. It would be a lot more helpful to post the code in a doc or text form. I think its unrealistic to be able to retype a 1000 lines of code straight from video. Also, it would be nice to have a little commentary on how you built it and what materials you used, etc.... But regardless, thanks for posting!
Hi man, its great, my little son goes to tennis club, I want to construct smth like this for him so he can practice, unfortunately we don't have Amazon, but still hope someday I'll make it, I see no problem in ball firing part, but ball feeding and swinging is not yet clear to me.
This machine looks like a wonderful prototype, but the one thing that makes this difficult to sit through is this unbearable noise lol. Is this heard while you’re using it or is the mic just making the noise worse?
Hi, Great work may i know what is the velocity of the ball existing and how much distance covered by the ball ?, it would be very useful for my college project @Buildit Makeit
Hi. Looks great! Can you please tell how did you make those ball launcher wheels? I am also doing a similar project but my wheels are wobbling a lot, so not able to run the motors at high RPM.
Hi, Bought the wheels from internet 125mm dia. they are nylon inner with a rubber layer attached. its important to balance the wheel to eliminate vibration. I placed the wheel in a lathe and re bored the centre of the wheel, then made a brass shaft to fit the wheel on. I then balanced the wheel with shaft by placing the shaft on two stanley blades in the vice (CAREFULLY) you then simply look to her the wheel rotates to and drill a bit of the plastic out until you get it balanced.
Hi there are 2 of 24vdc motors rotating two 125mm dia wheels in opposite directions, the ball is dropped into the center of the two rotating wheels and compressed and thrown out. The wheels rotate at around 3000 rpm.
Great project! I am trying to build a similar machine, leveraging a broken older ball machine. Is it possible for you to share the sketch code for Arduino? Thank you in advance.

Hello! That project looks amazing! Would you be able to describe how you managed to attach the wheels to the motor shaft? I'm assuming you had to use shaft couplers/hubs and maybe extenders? But how did you get the wheel to stay attached? Was it a direct mount? I'm trying to make my own project, but I can't figure out how to get a castor wheel to attach to the motor shaft (especially when the shaft is
Motor shaft is 8mm dia, i turned a shft to 16 mm, drilled the shaft to accept the 8 mm motor shaft and drilled the wheels to 16 mm, two small screws through plastic wheel hub into shaft. all needs to be accurate to avoid vibration as the motors turn at 5.5k rpm

Wondering how you will go with many balls stacked in. Ball jams will be a problem maybe.
Hi great project! is it possible for you to share the project of how you built the tennis ball machine?
You actually do not need all that complicated metalwork for the ball track; two simple long springs, the type that pull gates closed will work.
can i see your wiring diagram?

Hello Amazing Machine .....What kind of batteries are required to run this (Voltage = ? and Amperes = ? and for how long this last approx.?
This machine looks like a wonderful prototype, but the one thing that makes this difficult to sit through is this unbearable noise lol. Is this heard while you’re using it or is the mic just making the noise worse?
great!!! how do you control the ball feed rate?

hello...
very nice project! I'm deciding to make the same for my project...
would you help me?
Very good project pls could you tell me the ball launching machanism?
