Maybe these could solve the problem of delivering power onto the rotating plate. I can’t help thinking there’s going to be a completely different way to approach this if we know the objective and audience for the wheel. speed control will be smoother with the reduction ratio of motor shaft to rim diameter, Direct motor drive of the spindle will require a lot of power to vary, but the flywheel effect may help in other areas. The motor can be a lot smaller, and take a couple of seconds to run up to speed. One possible variation, is driving the disk from the edge, with rim, belt or idler drive like a turntable. I like the idea, and can’t think of another way immediately, but it’s going to be interesting. If this is spinning and shatters, it can do a lot of damage. I’d suggest determining all the physical parameters, including weight and position of up your on-disk hardware, the rotational speed etc, then going to visit your local university physics department to identify what’s needed, including out of balance auto shutoff etc. The internal stresses and spindle loads are going to be significant. I can’t help being fascinated, at a big ‘propeller’ display, but also very concerned at the moving mass.Īn acrylic disk, of around 1m diameter x ‘say’ 10mm thick, is a solid chunk of plastic (and expensive). That would make for a resolution of 128x144 with a ppi that heavily increases the closer you come towards the center. If my calculations are correct, with 8 blades, I could have 128 blade positions running at blades But would that even be remotely enough to get a reasonable resolution while it rotates? So I could have 442fps without any rotation. So if I'd cut the 144 in half I'd have 2 72 LED strips that could run in parallel. I think it takes 30μs for every LED in a strip to update. One more thing: Can the strip even be updated fast enough?

How to get the 2 wires to deliver power onto the rotating blades and thus to the leds and microcontroller? Or should I transmit the power wirelessly? (I need about 9A there anything else I missed?

What motor would I need? (In the end I would like to get at least 30fps, so 1800 rpm I guess)

Which material should the blade be made out of? This way I'd only have to find a way to get power to the microcontroller. I would probably place the controller in the middle of the blade and have it connect to the LED strip from there. I mean in theory I just need a motor, a blade that I stick the LED strip on, and a microcontroller. Now I was wondering how difficult ans expensive it would be to diy build a bigger version (1meter diameter) of that with 144LEDs/meter LED strips. I recently came across these LED fans that simply have a blade with a bunch of RGB LEDs placed very close to each other and are thereby able to create a sort of hologram display: REVIEW: 3D Hologram LED Fan Display - Future Is Here! - YouTube
