Window of Opportunity Ball Machine
« on: November 10, 2017, 05:52:36 pm »
Hi all, this is the first update video for my Knex ball machine that I'm working on. I'm pretty low on parts, but hoping for some for Christmas.

Link to path switch briefly showed in the video: https://www.instructables.com/id/Knex-3-Way-Geartrain-Switch/

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
    (https://youtu.be/_ApMoeGhc6o?t=27s)
The white floors that look nice are often at a very subtle angle, enough to get the ball to a certain point on it.

no, i'm asking about the structure that holds the white floor, I see alot of people raising it up by a blue rod, is there any particular reason for that? should I do it too? like in the first update video for  citadel, the floor is raised up a little, what's the reason for that?

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?

Having the floor up a bit makes things easier: You will have to lift up balls somehow, and there are very few lifts that lift up a ball from ground level, usually they start at like a blue rod height, or even a red rod height
This is a signature.

Thanks, I've decided to have a split level floor, since the lift i'm developing will be able to pick balls up directly from a white floor
