For a real spinning top over engineered https://youtu.be/QLTsxXNekVE?si=S31kpZQHiYlUSedx | |||||||||||||||||

Freaked me out for a second and had to double check that my tablet comes with a stop watch without having to download an app WITH ADS!!!!! Does he earn money for displaying these ads in his video too? I find it hard to believe that a content creator with sponsors is forced to use an ad supported app. Something about it being a stopwatch really just adds the cherry on top | |||||||||||||||||

There is a Japanese show that made a Scientist vs Engineers version to build the best Spinning Top: https://www.youtube.com/watch?v=-q-hcidtjiM Awesome! | |||||||||||||||||

I saw this and, while interesting and impressive, this isn't really a spinning top. It's a gyroscope. I was hoping for a real like "I cast metal into the perfect shape that I physically derived somehow to last as long as possible" or something similar not just "I put a motor in a case and it spins" | |||||||||||||||||

Reminds me of this little top, which actually works quite well: https://limbo.top/ | |||||||||||||||||

I love projects like this. Taking something trivially simple and asking "but what if we really optimized it?" The material science discussion in these comments is fascinating. Never thought about how the contact point geometry matters so much. Diamond tip makes intuitive sense for hardness, but then you need something it can spin on without scratching... | |||||||||||||||||

Saw this last week, really enjoyed the tenacity in problem-solving!! Did make me wonder if you could build a solid state one using well-timed pulses through an electromagnet that provide torque through the field interaction with the earth's magnetic field. Not much torque available there obviously, but on a per-revolution basis you don't need much. | |||||||||||||||||

My mind immediately went towards Battlebots when I saw electronics getting involved. I wonder what else would need to be done to make this steerable over RC? There may be a lower weight class where some nicely CNC'ed 'Phantasm Orbs' can score reasonable points. | |||||||||||||||||

I like it, but part of me thinks that spinning tops should be without IC and batteries. I don't mind some steampunk clockwork mechanisms though. | |||||||||||||||||

This is fun, well done. Quite a performance to reach 2 hours on that little battery. Perhaps Euler disks are next? | |||||||||||||||||

Entertaining, but holy cow that music distracts from the content. | |||||||||||||||||

These would make great pomodoro timers. | |||||||||||||||||
