I can't find an example of what you're talking about. Could you maybe show me a screenshot or tell me the timecode on the video that you're looking at?

When you say "flat base" are you asking about the white floor that the ball goes on or the frame that holds the white floor?
The frame should be flat on the ground, and the white floor should be on at angle. The only reasons I can think at to why your white floor would be flat is:
  • You know that the ball's momentum will direct it to a certain side of the floor
    (sort of like a path but nothing keeps the ball on the path)
  • Your bedroom floor is not flat
  • You're making the floor from Sandro's Elysium

The white floors that look nice are often at a very subtle angle, enough to get the ball to a certain point on it.

TIL Knex also makes micro gears.

Project Ideas and Help / Ball machines that are quick to make
« on: November 02, 2017, 10:34:19 pm »
Occasionally my cousins (4yo and 8yo) come to visit and they want to build a ball machine with me. Usually they have to go home before we're done.
I was hoping someone could recommend a simple design that I could build with them in under two hours.

My design was one lift, two tracks, one element, and the whole thing was 3 red rods high. Maybe someone could also recommend the easiest lift and element to make?

What causes the machine to draw spirals instead of circles?

Instead of making a community Youtube channel, we could instead make a Youtube playlist which contains videos from all our existing channels, and then feature the playlist on the front page of Knexflux.
This would be less work than a new channel, but would achieve the same effect.

EDIT: I forgot that the desired effect of the channel is to attract new people to this site.

I think the problem is that there is too much friction. Maybe add more wheels, or put tires on the wheels.

I really like how compact that is.

If you're happy with the turntable going at 5.8 RPM then the gearing wouldn't be too hard, as you'd only need a small blue and large yellow gear.

I'm not exactly sure what you mean, but this might help you design the gears:

I could turn this into a selector, but I can't think of a reason I'd need logic gates.

I could also use this to engage/disengage a motor, but again, I can't think of a reason I'd need logic gates to do that.

How big do you want the drawer to be?

I had a plan to make that, but add in an entrance track, exit track, and a way of resetting the element.

Then I forgot my plan.  :-\
