Gregory's Server@skobkin if you dont mind jerky movement that might work... in practice id imagine it would be harder than it seems (or else it would have been done)

 @skobkin well there are chessboards that move pieces though.. a few models.. the reason i think it may be harder to do is becasue why would they build all these fancy robots inside the board that use magnets to move it.. surely the first thing they tried was a grid of coils.. surely, at least before designing a hoard of robots inside the damn thing.  @freemo @skobkin im not so sure of that.. i mean wire isnt that expensive, and those robots need to communicate nad have processing power... id imagine the coils would be cheaper, at the very least affordable.. just taling about some chunks of iron and a bunch of wire. @skobkin yea this is one of those things we would have to test.. im not even sure how much power youd really need. @freemo But... Moving pieces are still fun! @skobkin usually electromagnets using thin wire wth many turns @freemo Yeah, it's more efficient, but minimally sufficient thickness of the wire is still a thing to determine. Also a subject for modeling and calculation... All this sounds like a very interesting engineering project. @skobkin very doable without much advanced EE... but still a tehcnical challenge. Sure, would be fun. @freemo @skobkin being done with a small ball: https://incoherency.co.uk/blog/stories/electromagnet-grid.html @freemo |
@freemo Yes. I was thinking about jerky movements in the first PoC model. Then it could be fixed by utilizing magnetic field pulsation with real-time position tracking.
We'd obviously need teflon mats for each piece to reduce friction.
Of course it's be harder than that, but... The sole fact that it doesn't exist doesn't mean that it's very hard to do. I mean if these guys didn't slap a tablet to the chessboard while making it RGB-lit at the same time, I wouldn't think that someone needed that at all... But here we are.
Good luck with this campaign by the way. Hope it'll be released and delivered to you.
