Improve, completely expand and test my DIY homemade tennis ball machine
In this video you can follow the complete conversion including functional tests. Another video will follow later with the operation and the many possibilities of putting together different drills. Not just 20 freely programmable drills, but until the SD card slot is full.
Feel free to get suggestions and feel like doing it yourself, it's not that difficult.
Have lots of fun with it.
In diesem Video können Sie den kompletten Umbau einschließlich Funktionstests verfolgen. Später folgt ein weiteres Video mit der Bedienung und den vielen Möglichkeiten der Zusammenstellung von unterschiedlichen Drills. Nicht nur 20 frei programmierbare Drills, sondern so viel bis der SD - Kartenplatz voll ist.
Holen Sie sich gerne Anregungen und Lust aufs selber machen, ist ja nicht so schwer.
Viel Spaß dabei.

Well done!!!
🤘 Amazing project!!!!
Nice project. Congrats!!
Very nice.
Thank you
Hi Wolfgang. Firstly thank you for share all the steps of your tests. It is amazing. Could you share what was the filament used in this new project?
Hi Mateus, the parts have to be as stable as possible, so I used the "Flashforge ABS PRO" filament.
@@wolfgangbisinger Thank you sir :)
Wolfgang this is very nice. and thx for share all your files. i start printing today 🙂
Thankyou
@@wolfgangbisinger you are to thank for. just a question, the motors, are thethe model BPM-24-3000?
@@johndemeyer4613 Hello, sorry but BPM-24-3000 doesn't tell me anything. I can't get to the labels on the motors either, so I'd have to remove them. Both are regular NEMA 17 stepper motors, one with a 90 degree worm gear with a ratio of 17:1 1.5 amps, the other has no gear and is 2.5 amps. I hope this helps you.
Or do you mean the server motor?
@@wolfgangbisinger No, the servo motor is oke. i need the trowing motors, cheapest i can find is €110 😞
Thank you for sharing! It is so far the most useful video and guideline out there! I am building my girl friend one, from your video the 3d prints looks very strong. But I am just wondering about their durabilities, would they com apart over some time?
Hi, Thank You.
In my opinion, how long the printed parts last depends on the plastic used and the quality of the layer adhesion. I have been using some heavily used parts of my machine, such as the ball turntable, since 2019 and cannot detect any cracks or breaks. If a part broke, it was not due to the material, but rather due to incorrect handling
@@wolfgangbisinger Thank you again, very delightful to know!
👍🏻
wieder ein sehr schönes Video. Super Maschine! Kannst du mir sagen, wie schwer die Rollen sind, die die Bälle rausschießen? die müssen ja recht schwer sein, damit die Bälle auch entsprechend weit fliegen oder?
Ein Rad wiegt 400 Gramm.
@@wolfgangbisingertop, danke!
deine Motoren laufen auf 12V oder? was für ne Batterie verwendest du da?

Hello Wolfgang,
I recently visited your blog page to examine the circuit diagrams, particularly regarding the H-bridges you utilized for driving the Lobster Server motors in your project. However, I noticed that the diagrams only mention "H-Bridge" without providing detailed information. Could you please share a link to a page where I can find more comprehensive details about these H-bridges? Thank you.
Hello,
In the Word file "Teileliste_Gleicheachsen_alles.zip", one line above the circuit diagram "GPIO_Belegungsplan.zip", you will find the link to this website:
display3000.com/shop/elektronikmodule/h-bruecken-_-fahrer/index.html
You can find the exact description in the details of the H-bridges.
By the way, I operate the H-bridges with 3.3 volts instead of 5 volts as prescribed, works perfectly.
Good luck
Hello@@wolfgangbisinger, I'm afraid none of the links you provided above work for some reason.
@@CagdasAkalin
sorry, RUclips changed the link. Next try:
@display3000.com/shop/elektronikmodule/h-bruecken-_-fahrer/index.html
Sorry no work
Go to my website, you can find the link at the top of the video description, in the download area download the parts list as a Word file from the machine with the heading 'Downloadliste für die Version vom Mai 2023 mit dem Raspberry Pi 4 - Python - Programm gesteuert:' down
Thanks. Can u pls share motor, shaft and wheel specs.
I installed original Lobster server motors and wheels, see also the answer from johndermeier4613 below
