Could somebody please post an instructable on a simple, cheap, and easy to use tennis ball launcher?

I play tennis and would be very grateful if I could have a cheap ball machine to send me balls.

Oh, if you look at the bottom of this https://www.instructables.com/id/Build_A_Net_Gun/ it has a Tennis Ball 'modification', you could set that up with a simple frame and extended trigger.

Was this what you were looking for? Or something simpler?

2 counter-rotating wheelbarrow tires, a motor, and some way to send one ball at a time into those wheels...and a hopper to hold balls. that's the most common... You could build a repeating pneumatic launcher, but that's less easy to control the speed (I think).
