@@dertythegrower yep.

Yes a styropyro collab would be awesome, I could see him making this insane. Especially if using a DVD writer laser

Would you consider a Flymo a ground effect lawnmower or would it be a hover mower?

3d printed autonomous laser GEV lawnmowercat waypoint mission (with vacuum impeller)

Those reflections could sear your retina, and at a decent distance. Lawsuits are why this isn't a thing.

same for me, we should consider a low-tech variant like this one kzfaq.info/get/bejne/ZpOXfZxjzsjadH0.html 😄

or use the distance as an indicator to switch the laser off, when there isn't a target. We could call that a "safety".

Yes definitely should use an oscillating focus

I was thinking that. Maybe get an autofocus off an old camera or something, something motorised that focusses. I think he was lucky enough to find his existing lens worked to extend the focal point though, getting adjustable focus might push it into real, actual, optical work and beyond just gluing stuff together from his 3D printer.

This is a fire hazard.

@@richardwicks4190 yea, using a form of energy to mow your lawn is a fire hazard, what's your point?

Same, I have lasers that aren't built with proper interlocks and I keep the locked up like they're guns!

Anyone else flinch when he was using that huge, dangerously overheating vacuum to suck up explosive sawdust indoors on a carpeted floor?

@@rubiconnn yeah, if some of those sawdust pieces started burning on the motor, he’d practically have a flame thrower/torch

@@rubiconnn don't youse even worry about it pal

@@iwenttogoogleheadquartersa1397 This is a vacuum so it wouldn't be a torch or flame thrower.

Good way to start fires, burn animals and people, blind animals and people, and put yourself in an awkward position when the investigation into the wildfire leads to some idiot with an illegal high powered laser, breaking every safety recommendation, because he saw a video of another idiot burning his grass.

bro ive never had an original thought

@@ejdelay4715 original is only relative to other things. lasers are designed by someone, but were probably inspired by other people researching about light and the sun. everything starts from an idea, and most things today are just someone else's idea but better and cheaper to produce because of capitalism. anyone can start a trend, and most things that get popular are not original so don't blame yourself for being inspired. you have probably thought of new things at one point, so don't give up on your dreams.

Dude!!! My parents had an electric lawnmower, it had to be plugged in, there was 200ft of electric cord to manage during the lawn cutting process and then wrapped up. I had the same exact thought about the laser with perimeter mirrors!!!

Every lens more eats some 10% power what that beam got before going true it. Same thing every lens and prism. That multiple spot laser is bad idea, you can get only one in optimal spot, if you aim it to lens. Those diode lasers called pussy lasers, there is CO2 lasers and maybe Ne-He gas lasers should work too. Then use fibre and small lenses to point power where you want. If that kind technic could cut 100mm titan, some grass cannot be end of world for it.

This world is rapidly passing away and I hope that you repent and take time to change before all out disaster occurs! Belief in messiah alone is not enough to grant you salvation - Matthew 7:21-23, John 3:3, John 3:36 (ESV is the best translation for John 3:36) if you believed in Messiah you would be following His commands as best as you could. If you are not a follower of Messiah I would highly recommend becoming one. Call on the name of Jesus and pray for Him to intervene in your life - Revelation 3:20. Contemplate how the Roman Empire fulfilled the role of the beast from the sea in Revelation 13 over the course of 1260+ years. Revelation 17 confirms that the beast is in fact Rome. From this we can conclude that A) Jesus is the Son of God and can predict the future or make it happen, B) The world leaders/nations/governments etc have been conspiring together for the last 3000+ years going back to Babylon and before, C) History as we know it is fake. You don't really need to speculate once you start a relationship with God. Can't get a response from God? Fasting can help increase your perception and prayer can help initiate events. God will ignore you if your prayer does not align with His purpose (James 4:3) or if you are approaching Him when "unclean" (Isaiah 1:15, Isaiah 59:2, Micah 3:4). Stop eating food sacrificed to idols (McDonald's, Wendy's etc) stop glorifying yourself on social media or making other images of yourself (Second Commandment), stop gossiping about other people, stop watching obscene content etc. Have a blessed day!

Right. And maybe think of aligning the laser vertically downside and just rotate a 45° oriented mirror.

I love when engineers improve efficiency and safety. _"You have a laser that can blind in nanoseconds? Add mirrors! The more reflective surfaces, the better it works!"_ XD

@@MomannBudd my thought from beginning of this video. The beauty of lasers is that you can keep them stationary and align optics robotically to move the beam in 3D AND adjust focal length....

Excellent observation and suggestion! My fear with his idea is on the rare chance of some stranger deciding to play with the laser when he's not looking and suing him for damages. Creating a housing for the laser is an interesting idea that I'd love to see him tackle. It may even be a faster cut due to the mirrors.

Great idea. And keep the laser contained in a box that runs over the grass, like a conventional mower.

Using a 40-watt laser outdoors he's arguably more dangerous than shooting your gun at the sky randomly. If somebody goes blind because of you doing this or you will go to jail or you will have to pay that person an insane amount of money

Was looking for this comment🤣

Same.. was waiting for someone else to mention this! :D

That would even be good for etching guide lines for painting a regular mural.

Good idea

Yes we definitely need to see this!!!

Downside is no-one is allowed near the mural and you'll need a at least a few layers of opaque sheets blocking the reflected laser light.

That would be a much better use than making a patch of grass look ugly

maybe you just have no idea what your talking about which is why it seems dangerous.

@@bryannonya9769 No its pretty insanely dangerous. I'd hand a loaded full auto AK to a child before handing them one of those lasers. Also note, across the world children operate AK's every day, so that's actually pretty common. Those lasers though are extremely powerful and dangerous due to just looking at the spot causes permanent eye damage, and reflections even worse! The chances they harm themselves are above 50%, while with an AK I'd say its like 1/100,000 and typically its kind of hard to aim it at yourself with short child-like arms other than your foot, so its severity level I'd rather have eyes than feet anyways.

Neighbor looks over the fence at the laser. Sees the reflection off a blade of grass and has a permanent blind spot in his vision.

A motor to turn the old camera lens' focus over time

tbf if you can afford a laser array, you can probably afford to level your lawn

that’s actually an amazingly advanced idea that would also be possible with todays technology. would take a lot of development but very impressive

@@alexbogiatzis9855 also, if you can afford a laser array, you can also afford a gardener lmao

My first thought after having read your comment was "What if it just didn't scan the yard?"

Is it weird I had the samw childhood belief?

can't explode the grass if it doesn't provide enough energy to do that

@@5omebody can explode the grass if it does provide enough energy to do that

Those things can be over a hundred grand though and weight as much as I do. They are also way the fuck more dangerous than this laser. But fuck it, he should do it!

Why not shooting depleted uranium rods or blades with electric energy acceleration and those cut nice lines point a to b. Then send these every few mm apart and you get smooth yard. And waste "blades" fly far away, so it's environment friendly for your plant.

somebody One coffee cup of grass have energy enough to explode a car to disappear, if you know how to relase that energy fast enough. That's not only theory, it's true.

you thought a regular lawn mover blade was to much hassle well now you can have a lawn cutting laser🤣🤣🤣

Or maybe lenses and mirrors to directly use the sunlight?

it would take him 5 years to mow that lawn.. there's no point.

Don't worry though. Most spiders can actually regenerate limbs on molt cycles, and many have been documented self-amputating trapped or damaged limbs without hesitation.

@@trenchrot Not to mention that brown recluses aren't found in washington and sac spiders are

look up Husqvarna automower

The accelerometer was in case something knocked it over, ot if something walked into the beam.

still doesnt seem to raise above the horizon

@@drumlineking07 Yeah but "knocked it over" and "moving it around by hand" should be the same. An accelerometer only measures acceleration - no matter who how what is responsible for it.

@@aerolus Yeah by luck? An accelerometer cant determine if it raised above the horizon or not. Either there is no accelerometer, it malfunctioned or the logic that detects abnormal movements/accelerations was too forgiving.

@@CocoaPimper i thought you were referring to him putting his hand in the laser (which wouldn't have done anything). That being said, he might have it set up to detect tilt (like something knocking it sideways) and not to detect a sudden jolt in any direction (which obviously would've been better lol)
