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.
These are the rubber bands.
Make sure to watch the video, there’s a little interesting surprise at the end:
So… beautiful… I must have one!
That's pretty cool.

Wow nice, did you make this yourself?
And your dog would have loved you forever.
You did all this by yourself? That's amazing!
I mean, it's not too complicated a design, but it would've never occurred to me to do something like that.
Thanks a for sharing this, and I liked the arm at the end of the video!
I want one!
All I can say is: 'wow'. Astonishing piece of engineering. Looks very professional and actually… a bit 'military-grade'. I can't wait for your next invention : )
How do you do it?! I'm a little bit scared you'll invent a minituare nuclear warhead.
* miniature. D'oh!
Looks like it would get the job done, nice design.
Wonder how far it would throw =3
I bet that would be fun with some cherry bombs or smoke balls nice
