This is an older video on the Veritasium YouTube channel talking about the real moral dilemma of self-driving cars. I’m posting it, because he includes real data with real numbers enforcing what I already assumed would be the case.
More than 30,000 people are killed in the United States in automobile accidents every year, and 2,000,000 more people are injured. In 94% of collisions, the problem is driver error. In 2015, half of all traffic fatalities occurred on highways.
It doesn’t matter if the self-driving car needs to make a decision where that will either result in either the driver of the self-driving car or a person on a motorcycle will be killed. What does matter is that self-driving cars can save lives today. Even Tesla’s autopilot can help save lives.
Non-planar 3D printing isn’t new. The first video demonstration I saw was published right around the time I bought my 3D printer in 2014. At the time I was less impressed by the non-planar aspect of his demo than I was by his idea to reuse support material between prints.
3D printing is usually accomplished by printing one layer, moving the print head up a fraction of a millimeter, and then printing another layer. Non-planar 3D printing involves moving the print head up and down while printing a single layer. This not only gives you a smoother finish, but it also provides additional strength.
The original video showing off this work is awesome, but rather dry. Teaching Tech has done a fantastic job explaining what non-planar 3D printing is, and he explains the entire process of how he got up and running with his own non-planar prints.
It is a bummer that the non-planar changes to Slic3r were made to the old Perl codebase instead of the new, updated PrusaSlicer for of Slic3r, but I imagine they started work on this long before the PrusaSlicer port was released!
Learning Epicness. This video on StingersSwarm’s channel was published a few months before my friends and I started flying FPV quadcopters. It is a nice, short, impressive video, and it has definitely been inspirational for me.
When I first saw the video, I didn’t even understand how to make a miniquad make these kind of maneuvers. When I watched the video again six months later, I mostly understood what was going on, but I didn’t think there was any chance that I could ever do anything like that.
I watched this video again this week, and I’m excited. This time, I feel like I could manage to do this. It’d probably take me all day, but I bet Stingy was flying all day before he got this right back in 2016, too!
Pilots, including Stingy, are doing much more impressive things today. Even so, Learning Epicness is still an awesome video today!
