Ball throwing machine

Some time ago I started building a little ball throwing machine intended to entertain my dog.
I didn't really finish it due to lack of time but here you can see what I ended up with:

 More pictures and videos after the break!


The basic design is a conveyer belt driven by a geared motor. There's a pin attached to the belt, which pulls back the slide.



As you can see, the conveyer belt is driven by a geared motor. Originally this was a cordless drill.



Here you can see the pin which is pulling back the slide.

These are the rubber bands.



Make sure to watch the video, there's a little interesting surprise at the end:

    I mean, it's not too complicated a design, but it would've never occurred to me to do something like that.
