A simpler way to maintain steady pressure with simultaneous puffs would be to use a oversized manifold, and put the valves on the end of the copper air lines, perhaps mounted on a board or something. Maybe you could gang up a number of puffers for larger parts.

And what about doubling the bins by placing them on both sides of the belt, with puffers blowing in both directions?

Or a laser trip sensor to get a more precise belt location measurement?

Fun project!

That's an option. But the problem is solved so that part is ok now.

It does that, you can see it in the video if you look closely and also in one of the pictures. There are two bins at the back and four in the front (that's the easiest way to fit them right now).

Or a gray code printed on the belt! That would give you absolute positioning.

Absolutely!


A laser per bucket could be integrated with no change to existing software. Just AND the valve signal with the laser detection signal.
