Homemade Tennis ball thrower 

Hello, very nice project ! I'm going to try it. Thanks a lot for sharing the design, it rocks ! Did you try to modify the speed of the wheels to generate slice/lift ?

Thanks for sharing all of the fabrication images and CAD. What boards did you use for the wireless switch?

Thanks for this. you just gave me an idea for a ball thrower for my dog.

Any idea of the total current draw from both motors?

Waiting on a few bits and pieces . Am trying with two 775 motors. They take about 1 amp at 12 volts and spin high revs. I'm guessing 6000. Nothing to measure with. What's the ideal spacing between wheels? Almost ready to fly out my first ball. Heads up!

Hello Rich, congratulations for such nice work! I've accessed all the files you provided in order to build a machine like yours. But I'm afraid I'm not capable to develop the Arduino code to control the device. Would it be possible if you share it too? I suppose you don't have commercial intentions with this project. Me neither. Thanks

Hello Is it possible to order you all the parts and the manual to assembly ? If yes, how much will it cost ? Many thanks Seungkyu

Hello man!! You are awesome I was looking forward to make it from soooooo long but couldn't find a good design but but but You just solved my problem man!!! Thanks brooo......

love stuff like this. You're the man.

That’s pretty good

Can you show pictures of your ball feeder wheels. I have no clue how this is workig, even after looking at cad files. My feeder always is getting stucked and wont feed balls anymore

Thanks for sharing, this is awesome project!

Outstanding!!

hello Rich how are you? how are you doing? I'm setting up my tennis machine project, I didn't quite understand how your tennis ball feeder works, can you share more pictures of it with me, how to attach it and what material is used to assemble besides the bucket? Thank you

Looks like you could use stronger motors . The MY motors would be more suitable.

Great job! What kind of motor did You use?

Hello there RichVideosNH,,,can I use your new dashcam clip in my compilation? Any comment what happened? Thanks

How often are balls jamming up?

How did you fixed the wheels on the axis where the motor is connected to?

Hello, Amazin project. How can we find STL files of 3D prints parts?

Im progressing with my own project. Instead of the tiny 775 am using the heaftier my6812 motors. Using a car window winder motor to turn the disc. Am wondering how troublesome the disc mechanism is and how prone it is to jam ups. Im almost done and will post my own video soon. Hoping within 6 months anyways. Just a pet project.

Hello sir can I know the dimensions for all those aluminium you used?

So, I need two motors, 7000rpm what wattage?

could you please provide a sketch of your electric wiring including the remote control and batteries. upload as a picture onto Grabcad, thnx.

Rich, I'm trying to do a ball thrower myself and I'm almost there. The problem I am having is to find a motor for the feeder that can rotate all the balls 45-50 in the bucket. As you said, yours probably holds 35, any suggestion of a motor I could use? Great work btw!

FANCY!!!

does it ever jam?

I'll give you $300 for one. When does the shop open?

Hi, How many balls does the feeder support?

Plz give motor purchase link,

Hello, beautiful design! But I would like to know how long these Screwdriver batteries last, and if it would not be interesting to use a UPS battery ??? thank you!

Rich, one more question for you. Where did yo find the mounting plates for your motors to attach them to your extrusions? My ball machine today is mostly done in wood and after seeing your project, I'm thinking about converting it to extrusions as well (lighter). The structure seems fairly simple to be done (although I want to put a motor to move the bloc up and down as well) but where I get stuck is on the mounting plate itself. Did you made them? If so, can you share with me how you did it?

What did you use to make the Ryobi battery receptacle? Did you use the case from an old charger, did you find it premade somewhere, or did you do something very clever like 3D Print it? I've been imagining using a Ryobi battery for the power source on the science project I'm trying to help my grandnephew design and build, but short of cannibalizing my own tools for the receptacle or driving 60 miles to buy a not so cheap old tool off Craigslist, I'm darned if I can find something to work. I'd appreciate any advice you can give.

How do we get the dimensions from the model?

Your work is cool. I'd like to make a ball machine with my school work, can I get a drawing by e-mail?

Hola ,podrías mandarme algún manual de la electrónica sobre todo

wow!

You call this home made?

Hi Rich, how did you get the wheels to stay in place on the , like what is that thing that you built or bought at 0:45 called? I'm not an engineer at all; I'm a kid who likes tennis. Please let me know. Thanks! Edit: Also, where can I buy the extrusions (the frame I am guessing) and what are the parts called, v-slots?

How do you attach the thin fragile motor shaft to the wheel without it having the risk of breaking

How did you do electronics and programming?

Sorry last question Where did you purchase your extrusions?

I like the fabrication of the end product very much and regarding 775, with your experience can it sustain continuous usage of 30 minutes? Hope it's 60~70 feet of throw but have you had a chance of measuring the speed?

Hey rich, There is an option to share all the assembly files ?

Hello, Amazin project. You can share more details of wheels, motor e dimensions? Thank you so much

where do you get the wheel?

What is ball the speed?

Thanks. This is very helpful.

Hi Rich, Don't you want to sell your tennis machine?

RICH I'm a 100% Disabled Veteran and was wandering if you would sell all the fab parts to build one like this on thing I do is train dogs but it gets so harder than it use to. .I could really use this in making me able to do more and if possible please let me know. I could buy the motors and all but I cant fabricate parts I dont have that equipment and if I did I'm sure I would not be able to operate.

Can you give the 3D printed file for the step motor for the ball feeder

Hello sir can you provide videos of how to make it myself, I will pay your fees for guiding me how to make it .

#BOSS

Someone knows a machinist!

Hello.Really great your ball thrower. I would like to make one for my son, is it possible to have the file solidwork or plan? thank you

Hey brother can you give me a drowning this matching...I like it.. that's a good job.. thanks..

Can you tell me the ball speed?

Could i possibly you get you to make the parts if i pay you and i can assemble 9here maybe or i could pay for intire build if possible

So.... ... you REALLY spent about $2,000 in labor & high-cost machining capabilities in order to build a tennis ball shooter? Hmmm...

CRAP....YOU CANT BUILD THIS FOR EVEN 400 DOLLARS EVEN IF YOU HAVE THE EXTRUSIONS.....THERE IS AT LEAST 100 HOURS WORK IF YOU START WITH NO PLANS....

Could just buy one for less

That kinda sucs
