That poor Raspberry Pi is going for a spin dry!

Dale,

You have achieved a great solution, especially getting to be so balanced. For your project that is probably one of the major requirements, I think the wooden support structure shows how important a stable framework is for a project such as yours. It is very impressive. I also really like the fact that it still sounds like a sewing machine. It just shows that the sound of sewing comes from the motor and not from the rest of the mechanism - which is surprising.

Having worked with rotating things before, having made a sizeable DC motor, I am always wary of things flying off, does your sustem have screens for you ro hide behind? I was made to use Perspex cages for my DC motor but I preferred to just stand to one side!

It must be tempting to see how fast it might go, but then again, that might lead to destruction! How fast does it need to go to be effective with the LEDs? For most things to avoid flicker you need about 50 Hz which would be 3000 rpm.

Dalem very great progress! I like the sound of this motor when runs; you saved the memory of the sewing machine sound. It remembers ancient moments when I was a kid and this sound was frequently present in the homes of my school friends when the sewing machines during the 70s were always present in their homes; an effect on my memories like the Magdalena for Proust [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-772f3fca-5fb4-43a3-b4c4-57e9e8d35a8a/contentimage_5F00_2516.png:16:16]

By a technical point of vies, did you tried to run the motors as we can see in the video for a long time? Just to be sure that all the parts until this moment are reliable for the normal use? Sometimes, it is better to put a real full-stop to a certain point of a project before going ahead to avoid that issues will occur at a more advanced state of the development.
