I am making a tennis ball machine, and I've compiled a list of parts that I thought were good for the job. I am fairly new to this, so it is entirely possible that I might have overlooked something very obvious, and made a fatal mistake. Cos its my first project of this kind, there might be some obvious improvements that can be made. It would mean a lot to me if someone with a bit more experience could take a look at the system I devised.
These are the parts: (I will note if there are multiple)
CHUX Rainproof Switching Power Supply 700w 12v 24v 36V 48V DC CE ac to dc constant voltage LED Outdoor Power Supply 720W
14.5 should be enough, right? 12.5 for the main motors, and if I slow them while adjusting for the next shot with the other 2, the psu should be able to handle it? I can see that I am stretching it quite thin.
3D Printer U-type Plug Power Supply Switch Adapter Socket with Switch and Fuse July DropShip
Seems like an ok choice
48V Adjustable step-down module DC-LM2596HVS input 4.5-50V electric vehicle stabilized voltage power supply
quite a few
Seems reasonable. I don't think any ? < 48V component will exceed those 3A.
Spindle ER11 300W CNC Spindle Motor 52mm Router Bit Tools 0.3KW 220V Air Cooled Motor 3pcs ER11 Collet For Milling Machine
x2 for ball rotation control
I've looked around for what other people are using, and this one seemed more than reasonable. Still, I don't have much experience with this, so correct me if I'm wrong.
16A DC Motor Drive Module Dual Way H Bridge Control Board Drives IC
One of these looks like its enough to control both of the 300W motors.
DC 12V Gear Reduction Motor Worm Reversible High Torque Turbo Geared Motor 2-100RPM Mayitr Mini Electric Gearbox Reducer
I was planing on using the 6rpm one for rotating the ball feeding mechanism.
It should be able to keep on spinning at a constant speed with the load of a bunch of balls on top of it, right?
This is the kind of mechanism I'm aiming for:
Free Shipping!!! 360 / rotary encoder / FOR Module /Electronic Component
For keeping track of the 6rpm motor rotations.
1/2/4/8 Channel 5V DC Relay Module Solid State Low Level G3MB-202P Relay SSR AVR DSP for arduino Diy Kit
The one with 2 relays. One for the beeper, and the other one for the 6rpm motor.
C18 For Arduino Car Helicopter Crash Collision Sensor Switch Module Robot Model
I was planing on using this for finding the starting position of the mechanism for feeding the balls, but I think that I will scrap it, and just make the calculation based on when the first ball gets loaded. No need to know its precise position from the start really.
Electric Linear actuator 100mm Stroke linear motor controller dc 12V 24V 100/200/300/500/600/750/800/900/1100/1300/1500N
The 48v one with 30mm/s for vertical adjustment seems to be enough

A few things in mind
Those are the components I chose, and my worries, and thoughts on them. If you see anything wrong with my choices, please tell me where I can do better.
Thanks for taking the time to get to here
