High-speed camera mounted on a spinning lawnmower blade
Ғылым және технология
Mounting a Chronos 1.4 high-speed camera on a spinning lawnmower blade, and dropping things into the upside-down mower, recorded at 5900fps.
This started out as a project to see what the camera could take, turns out it can take a lot of punishment! Spinning up to 1800RPM, with about 200G exerted continuously on the periphery of the camera, plus another 100-200G of shock when an impact occurs.
The biggest challenges were getting balance correct, and finding lenses that could take high G force without going out of focus. The wide angle CS mount zoom lenses distort under high G, causing the focus to shift. Some of the earlier shots are slightly blurry for this reason. In the end I found a 2.8mm prime lens that handled the G force just fine.

I glanced at your channel and you appear to have an obsession with death. I want to warn you about the death that comes after the body has died. The death of the soul and spirit when the blood of Jesus is not found will end all fascinations about death and darkness. The one who finds himself thrown into darkness will curse every foolish thought that led him there.
Installed these on a riding mower kzread.infoUgkxetgfkJxfdT_B2vGYP-uNTLaBbim9OKTD . They were sharp out of the box, although I've never liked blade edges that were coated...not quite as sharp as I personally want. Using my belt sander, I removed the coating from the cutting edges and refined the edge enough to shave with them. So far, after three runs, these blades are holding up as expected. Even after hitting a few fallen 1/2 inch or so branches, the edges are still sharp as heck. No edge dings, no warping, etc. As far as installing them, the cutouts were of the proper size and shape to fit my aging Craftsman mower. Very satisfied.
I love how many people are focused on the Bad Dragon tentacle.
You are a mad man!! Reminds me of those old Timex commercials where they strapped watches on boat propellers, etc. I'm impressed!

Even though the process of creating it must have been very interesting in itself.

@@SailingFrolic Might be able to get by with just some image processing to determine the mirror location and orientation (probably just looking for the edges). Could throw a neural net at it but training that could be more irritating and complicated than necessary. Then it's just the image transform to align/rotate. Still, it could then get kind of messy with the inaccuracies of the mirror locations, but smoothing those values might suffice. In any case, we'll see if anyone ever does a mirror mounted version -- it's a good solution. Nevertheless, I think his video was also maybe demonstrating the resilience of the camera hardware? [Edit: Ya know what, you're right -- some white paint wouldn't hurt any of these processes. :) Also, I just realized the blade image itself, if in the mirror, could also be used for alignment. We could then go so far as to stabilize the images from a point on the blade... One step at a time though right? First step: KZread comments. Next step: 2019. Happy New Year!]

Excellent, both as a technical achievement and as a video. The passage with the colourful bouncy balls getting sliced by the oncoming blade looks rather Star Wars. Also give my love to Trixie, the helpful cat.
Great work. I was mowing high grass with a 3.5 horsepower gasoline lawnmower and hit a 1/2 inch steel pipe sleeve. The blade cut one side of the sleeve completely in half. It went through about an inch and a half of nearly 1/8 inch thick steel. The end of that blade is moving! My dad hit a roofing nail and it stuck in my leg. Better than the eye.
Needs a sharper blade. Thought of getting some tool steel blade stock, grinding it and drilling it to the correct fit, then case hardening just the blade itself. Did that to remake a cutting blade, and after it was hardened and quenched on the cutting edge it was able to hold a razor sharp edge. You do not do the whole blade, just heat the cutting end to bright red heat with a torch then quench in oil, anneal to a dull red then dump in insulating hot sand till cool, then grind clean and whet the end sharp again. Can get it razor sharp that way, and providing the rest of the blade is still not hard it will be less likely to shatter. You will need a better blast shield though, but you will get nice cuts. But who else would have though, just how much can a camera take G wise, you could sell those to NASA to be put in the engine compartments of rockets, though you would need a decent downlink to get the data off them at full frame rate, or a blast proof housing for use on a SpaceX launch.

Star Gazer Hard things are brittle things. If you don’t anneal something after hardening it, the first time it hits something remotely hard it’ll shatter. As with many things, there’s a trade off between wanting an edge that’ll stay sharp (hard) and an edge that won’t chip itself to bits (annealed).

@mrb692

Star Gazer, an experienced metalworker can use the color of the workpiece as a rough estimate of its temperature. From “coldest” to hottest, it goes cherry, red, orange, yellow, white. “Red hot” really isn’t that hot in the grand scheme of metalworking. Check out blacksmithing videos, and the thing they’re hammering on starts out white hot and by the time it makes it to yellow hot it’s back in the furnace. When hardening a piece of steel, it is rapidly quenched from a very high temperature (yellow or hotter), locking the carbon atoms in places they normally wouldn’t be. This makes the workpiece as hard as it can get. When tempering, the piece is raised to a lower temperature and allowed to cool slowly. This lets some of those carbon atoms relax out of their hardened positions, thus softening the steel. Crucially, because the annealing temperature was less than the hardening temperature, only a portion of the atoms relax back out and the piece retains some of the hardness gained through quenching. Starting the tempering process from a higher temperature or running for a longer time will result in a softer final piece, and lower temperatures and shorter times make for a harder piece. When a tool overheats and loses its temper, that’s because it was taken above the temperature it was initially tempered at. This lets more carbon atoms diffuse out, and the tool becomes softer. The practical bottom line is that a tool can withstand temperatures up to what it was tempered at, and since hard tools have low tempering points it’s critical to keep them cool.

Static vs dynamic balancing is a tricky beast to play with. Though, you managed to make it spin wonderfully well and balanced. Though, how much better then the original blade is it?
