Ah, the differential. The concept can be really hard to understand if you can’t see it in action, even if you have the sort of visual mind that car people have. Modern differentails are essentially the same, even in front-wheel-drive vehicles. Though many now have a small modification to the design that locks the two wheels together if the difference in speed is too great, making it easier to get around in the snow. And easier to do drifts. Another useful application for the differential is combining inputs, let’s say you hook what was one of the outputs to an electic motor and what was the original input to a handcrank, the original second output (which is now the only output) will spin at the combined speed of both the new inputs. I love gears and cogs.

Fooled around a tad with cars and seen many ‘helpful’ car vid’s. That diff video is excellent. Really takes the mystery out of them. Now for the LSD.

When I was a kid I saw that Harlem GlobeTrotters cartoon when they had to fight a basketball robots team. I’m afraid they may not win this time…

The colliding smoke rings are amazingly cool.

@ coconutnut

Now what we need to do is take two of those vortex cannons and collide the vortex rings that those make.

The vortex cannon was neat. Now I know why the Germans experimented with them in WW2. That small scale test is definitely proof of concept.

Who cranked out that fascinating explanation of differential gearing?

wow, the smoke rings collision was awesome.
