Does it actually work? Watching the video[0] it seems like the same end of the gyros keeps being pointed upwards/downwards. I suppose it's difficult to balance the slab of meat perfectly. Anyway, it's hilarious! Thanks for sharing. [0] https://transistor-man.com/PhotoSet/three_axis_gyro/animated...

It does indeed work! I've been meaning to instrument a food stimulant mass to determine how the chaos is effected my mass offset vs speed. I think due to the under-actuated nature of the system you're stuck with a balance between cg-offset, gravity and input rotation on the first axis

Have you noticed that a gyro sandwich is only cooked in one axis? I built a contraption to slow cook in multiple axes and documented it here: https://transistor-man.com/gyroscopic_gyros.html Not only is it tasty, it's mesmerizing to watch. Feel free to copy the design for your own festivities.

I have never cooked a gyro sandwich, I have, however, cooked gyro meat and used that in a sandwich

That said, this is really cool. I enjoyed the read.

it's all fun until someone gets gimbal lock?

Earlier quoted context omitted.

Is this guaranteed to be even on all sides though?

Yeah, it seems this free-rotating design would keep one side down if the center of gravity is not exatly on the intersection of all rotation axes. This might be worse than a common single-axis cooking.

I watched the short gif/video and I had the same thought. If you don't pierce the object/meat in a manner that its centre of gravity is on the very centre of this contraption, it would skew the spin and it affect its randomness in the movement.

But totally a fun project and cool topic to discuss on any BBQ
