I recently saw a video of a homemade badminton serving machine on station B, and I was shocked. . .
→→→ Less than one hundred yuan? I made a badminton serving machine by myself
→→→ XDM, I am more! ! ! Next Generation Badminton Serving Machine
It turns out that you can still play like this!
In my impression, the ball machine is a tall thing. It turns out that the principle is so simple, so I can also make one. . .
Then I searched for a ball machine on Taobao. Sure enough, the price is basically thousands of yuan to tens of thousands of yuan, but there are exceptions. There is a kind of ball machine that costs a few hundred dollars
. Simple, but it works!
Then, this ball machine also has an upgraded version, such as adjustable bracket, automatic shaking head, long and short ball control, remote control, mobile app control, etc. Of course, the more functions, the higher the price.
And other ball machines worth tens of thousands of dollars also have these functions, which may be better materials, high stability, and more convenient operation.
So I fell into thinking. . .
The cost of materials required to build a ball machine with basic functions from scratch may not be high, but the cost of time and energy is relatively high, and if you want to realize the additional functions later, I will do this!
Then I might as well buy a ball machine with only the most basic functions, and then improve its structure, add the functions I want, add a controller, add a wireless module and a Bluetooth module, and realize remote control and mobile phone control , Isn't this easy to catch?
Alright, let's do it!
