Regium: Extraordinary Claims Require Extraordinary Evidence

@Panagrellus i was also curious about that spinning behaviour somewhere in the first 200 posts :) - but i rather think it might be on plus for the board - the knight has no axial symmetry, nice piece, then imagine that the center of gravity is not over the middle of the circle of the felt but rather to the back (i think this is correct assumption looking on the knights head ) -= then there would be more , a little more friction to the back of head and it could rotate on that pressured point axis. Also the felt could have some disproportion of friction.

I saw one friction test of Felt on Youtube by Izmet (better call him Jonas, Izmet meas not a beautiful thing in balkan languages, also as Fekali does the same :) ) - but its tested on the symmetrical pawns.

You can also see there, frame by frame, how a real blur in _accelerated chess pieces occur, you can see multi frame images of a moving pawn not one blurred object (stop video and press , or . from the keyboard ). The multipoint reflection can come out from a strobe light for example from a fluorescent lamp :(

I have created a thread about creating and using eboards, please post some examples there. May be amateur / DIY (do it yourself) but also commercial examples are welcome. share your eboard knowledge there.

lichess.org/forum/general-chess-discussion/digital-boards-amateur-and-commercial-examples-rfc-i-do-reques-for-comments

Its also interesting as today Lichess started supporting electronic eboards with its new Board API - only for rapid+classical time control games and you dont need to use BOT account anymore: lichess.org/blog/XlRW5REAAB8AUJJ-/welcome-lichess-boards

I guessed that I was not the first to observe the spinning knights in a 900+ comments thread. Apologies for missing your earlier post.

"... a little more friction to the back of head and it could rotate on that pressured point axis. Also the felt could have some disproportion of friction...."

Maybe. But 1. not all knights spin (e.g. the first captured knight just slides off the board without any rotation) and 2. if they spin, they spin into an aesthetically pleasing position, to point the knight's head in an angle that a human would choose to make it look nice.

Ok, hardly evidence that would hold up in a court, but personally I would require an explanation for this behavior before I'd invest 650$ (;

Here's another proof of concept. This is clearly a feasible technology. Even if the board had to be thicker, it beat the s**t out of the competition. It will happen one day, just not today.

Too bad Regium couldn't be more transparent.

@SPINideas Cool video, if they used the ouija professionally, they would made good money for sure! ;) Their idea is possible, our notion that it is possible is the honey for appealling the investiment. The problem is that in order to do this, nowadays, it is very expensive and the market of wealthy chess players arround the world is, probably, not very wide... I imagine that is far easier to sell the wealthy a ferrari, a patek phillipe watch, a diamond ring or cloth of some known designer than a autonomous chess board... So... if it would cost 5000+ €/$ who would buy it? That's the problem. This had to be done with some cheap and common technology as "square off" in order to sell enough boards and have a profit.

And i want to add, from the reation worldwide, here and in other platforms.... there is interest from the average player in such a gadget.

@Panagrellus :) i didn't want to make it sound like that - rather to point your note that maybe somebody have written it ealier - didn't write it with a remorse :), sorry for that.

In the FAQ video i can see the bishop at 1:16 rotates counterclockwise. - in the Harry Potter video indeed the knights are all aligned pleasantly (sideways) but indeed a second earlier the black Queen's knight wasn't aligned like it looks in perspective. Well anyway if it was aligned for video i just have lost belief that they/he wanted to make a bad press around regium and only later show off the board that it really contains 800 pieces of coils and give it to testers. Now i am also sure this must be a scam and i should start looking for some working one or DIY board.

@SPINideas nice founding :) - i asked myself why the heck at the end of video they are showing that this actuator also works under fire... and the referal to a DiamondTouch from 2001 and i found the video - below - they were also playing with fire in 2001, debris resistant actuation.
Take a look at how high the magnetic coils are - little higher than in the previous czech university video.

@Mi5ter_t
Good spot regarding the rotating bishop in the FAQ video.
In summary: Bishops and knights sometimes rotate, sometimes they don't.

If we have an engineer or magnetism expert in the forum, it would be mildly interesting to know how the pieces would behave on a real board with a matrix of electromagnets underneath: would pieces spin around their axis while moving, or keep the same orientation?

@Panagrellus indeed in your video we can see that all the attracted objects except a paperclip sometimes rotate, sometimes not - only the paperclip follows his path with the part which has more steel in it.
It gave me to thinking that the rotation could also come from the disproportion of attraction - the part of the knight that is closer to a coil could be attracted more to the ground in front and i think it would be an unstable dynamic solution - if you have a book or a slab standing exactly vertically then it can start falling only at one of the two symmetrical sides :) - so the piece could start to rotate in one of the spinning direction but i cant see a reason that it should continue spinning.

When you move conducting object in magnetic flux, the changes of magnetic flux in the object as it starts moving will try to create its own field in a way not to let the flux change - but i see no reason in a symmetrical system as this one to force spinning only in one way.
