The first printed version, functional.
WOW! Compliments!!!
Really well done sir!!
That’s interesting. Where do the birds end up? Do you shoot them into a bucket?
Here’s the way I see it. Set the machine up on one side of a badminton net. You stand on the other side with your raquet at the ready. Start up the machine. Try to return the birds as they’re fired across the net.
I don’t think that room is big enough.
You need to go on tour with that comedy routine [SIZE=36px]??[/SIZE]
I couldn’t resist it.
Amazing! Well done my friend!!!
Wow, what a project, and all to practice badminton. Your passion & enthusiasm is amazing.
But it is not working. Nema17 does not have enough power. 
Why did you choose a NEMA 17 for this? If you need power/speed, you must choose a DC type of motor such as spindle motor! All of these types are easily controllable from an Arduino with a shield.
It is difficult for me to explain in detail in English.
Simply put, it’s easier to control a stepper right now. But the DC motor is not excluded. I want to try:
- weight counter
- a better driver for the stepper
- nema 23
- Probably DC motor with reducer
- redesign
I succeeded. With DM556 driver. The minimum amperage can raise is 3.2 A !
This machine keeps getting more & more sophisticated.
It is interesting. I can’t imagine how many hours of chopping and changing he has done.
The stepper was only for taking a specific angle? I thought it was for throwing off the “ball”
I see where your confusion came from. Yeah, no, he’s had the throwing motor(s) set up since almost the beginning. AFAIK, they simply turn on & stay running until the machine is powered off.
Only tilt.
Turn.
