the Sri demo shows 2d motion. pcbs make it pretty straightforward to have an X and a Y array, but for some reason it doesn't seem to me like you can just easily drive both axes independently. could you really tune a 'step' to be on an arbitrary slope?
- jacquesm 5y agoI'd say that depends more on how much you are willing expend on hardware to drive it. You could slice your coils into tiny segments (essentially: just the tops) and then use the back of the PCB to drive them. They'd be magnetic pixels. Maxels?
- convolvatron 5y agogood idea - but that's alot* of drivers
- jacquesm 5y agoYou might be able to do something here along the lines of row and column addressing of DRAM.
- HeyLaughingBoy 5y agoIf you move X,Y separately but with a small enough step, it would be virtually indistinguishable from moving along the slope.
- jacquesm 5y agoInteresting challenge, can you 'microstep' along two axis at once without losing sync? That would be neat. I think I've worked out a way to rotate them as well!
- HeyLaughingBoy 5y agoI would imagine so; it should be the same problem as helical interpolation, but confined to two axes. https://infosys.beckhoff.com/english.php?content=../content/1033/tccncprogramming/html/helicalinterpolation.htm&id= https://infosys.beckhoff.com/english.php?content=../content/...
- klyrs 5y agoWith 4 layers, it would be a trivial extension to drive a y axis
