Show HN: I made Gyroscopic Gyro Sandwiches (transistor-man.com)

Have you noticed that a gyro sandwich is only cooked in one axis? What a missed opportunity.

The following details an elaborate way to slow cook food, using a handmade contraption. Not only is it tasty, it's mesmerizing. Feel free to copy the design for your own festivities.

Gordon Ramsay suggests you season and cook lamb evenly on all sides

>> challenge accepted.

Nice work.

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

I built a contraption to slow cook in multiple axes and documented it here:

Not only is it tasty, it's mesmerizing to watch. Feel free to copy the design for your own festivities.

My only critique is that you should have incorporated an aquarium somehow and added sous-vide to your cooking process.

Otherwise, a flawless piece of work.

And, the links to your friends are amazing and a treasure trove as well.

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.

Sadly for the title, I think the word you were looking for is "gimbal," not "gyroscope." A gyro rotates stably on a single axis. Your cooker "tumbles" on three axes at once. A gyroscope specifically prevents tumbling.

Doesn't a gimbal specifically keep the target object in a consistent orientation? This seems to function as an anti-gimbal

Admittedly this is a play on words, fair point! Gimbaled Gyro Sandwiches would be a better title

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.

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

it's all fun until someone gets gimbal lock?
