Alrighty then, I'll reserve judgement until the proto ships, I personally don't think you'll be able to fully isolate it with just 12 magnets, it would need some form of alignment pins if the magnets are in repel/repel to stop it skating off the side, if they're in attract/attract it won't skate off the side but it will instantly crash into the top or bottom and won't float. but hey, maybe you know more about magnets than I do.
Like I said there is a solution to the issue I just cant share it.
Like many others, I am highly skeptical of this IC:
1. The price range is too high, $300 of variation tells us either the design is incomplete or you don't know what interest will be like.
2. You can't make claims like "fully levitating" without having some form of proof of concept. You've provided no internal renders, yet claim that there will be no lateral movement. While this doesn't sound impossible, it does sound very difficult. If you're concerned about IP, you can always patent your design. But to make incredible claims with no proof-of-concept leaves me, and others, skeptical.
3. Is this your first board? If so, I'd recommend a smaller quantity GB like 50-150 units. Don't get greedy. An unlimited groupbuy implies you expect 1000+ orders, and at that quantity, you're most definitely taking advantage of economies of scale.
