Do you have a video? I want to see it in action for myself but like I said, i'm in the middle of my ball machine.

This looks really good, but I can't make it as I am in the middle of my first ball machine! I will make this though!!!

Sorunome 7 years ago

Yeah, you'll have to think of your own way to attach the motor, though

Wow! In step 3, part 8, it looks exactly like an optical illusion!

Sorunome 12 years ago

Maybe it IS one... :P:P:P

Knex1235 12 years ago

do you have a video

Sorunome 12 years ago

No, sorry. Maybe you could make one?

poncho531 12 years ago

Mine won't exactly be good, because I prefer to film it in one video, but it will be fine. When I cover the camera with my hand, that's path seperation.

Sorunome 12 years ago

That doesn't matter.
Please do the modification in Step 12 (I didn't add that as comment yet as i somehow can't edit ibles atm) that you use in that helix thingy instead of two yellow connectors only gold ones and wined the track all the way, I haven't tested that but that should make it work better. :)

poncho531 12 years ago

I will! After I finish building it....

Sorunome 13 years ago
