Disappointed to see the dots around it all appear to be the same spacing. They should be at different spacing, corresponding to strobe sync with 50 and 60 hz mains and 33.33 and 45 RPM. Hence four rings with different number of dots around the perimeter.
- foxglacier 1y agoThey are at different spacings. If you follow two rows of dots around, they fall in and out of sync with each other.
- nom 1y agoNow someone has to go there and drive around it at 33 1/3 rpm at night with a strobe light set to 50 Hz.
- card_zero 1y agoHmm. If the diameter of the circle that the car drives in is 14 meters, that works out as ... 54657 mph. I cannot endorse this from a safety standpoint. Wait, no, I was working in km instead of m, it's only 54 mph. Should be fine.
- dmurray 1y agoIt's one revolution every 1.8 seconds. That seems too fast for most roundabouts, but maybe not uncontrollably so. 78 rpm is Formula One territory.
