this is awesome. people have emailed me for years wanting a laser lawn mower (with a hilariously low budget of course) and i've told them it's not feasible. clearly, it was just a skill issue on my end. from now on, i will just forward these requests to you so they can invest in your amazing technology
you know it's a good laser video when styro says its awesome
You are why I came to the comment section.
holy shit you are still alive
definitely not a fire hazard. lol
Laser Jesus!
Laser Jesus, what kind of driver do I need to run DVD laser at
I know a 40w laser is dangers but I feel that having watched StyroPyro for a while my laser danger sense needs re-calibrating.
This is eventually going to start a huge accidental fire, for sure
Nah

On a separate note they now need to colab
@@dertythegrower yep.
Yes a styropyro collab would be awesome, I could see him making this insane. Especially if using a DVD writer laser
Daniel has now achieve his own Cinematic Universe, where his projects from other videos join together. Impeller vacuum, snowcat, even the peanut butter jar has a cameo.
Now we need to see a RAM/ground effect lawnmower.
I second this!
Don’t forget about the stratus LED, that’s his as well
@@gtjack9 True!
Would you consider a Flymo a ground effect lawnmower or would it be a hover mower?

When lasers were invented it was said they were solution looking for a problem... I think using one like this falls into that category. Love it.
Lasers are my favorite example of “I invented… something… for some purpose I’ve yet to find”.
Something may seem useless at the time, but I guarantee the guy who invented them didn’t think about everything from barcodes to CNC machines to really slow lawn mowers
Only mower yet invented which mows slower than the grass grows!

@@MaxxTheSavage This!
When I was a kid imagining my future laser grass leveler, I imagined that the grass would be mowed to the desired level first, then a mirror fence set up around the perimeter. The laser would strafe along one edge of the lawn daily to maintain the same level height. This is somehow just as impractical. I love it.
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.
auto mows grass while dogs taking dump
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!!!
Your design process has streamlined so aggressively this year that I barely see you prototype anymore. It used to feel like projects took years and still looked unfinished but now it's a different story. Amazing!
"I barely see you prototype anymore"
I am not him an I don't know. I assume that he selects video content of based on video engagement.
For example: research/background 20% to 20%, building 30% to 20%, and usage 50% to 60%.
I actually contemplated a similar idea, about 35 years ago. Despite the considerably 'weak' lasers of the time, my design was to point a laser down, and deflect it from a mirror. If you were to combine this with a video system, that optically observes the laser, a servo could be used to trim the mirror up or down, for uneven terrain.
Now, assuming that you wanted to run this device continually, 24-7, you might want to put up some barriers, for example, on the fences, trees, or other things that you'd rather not be 'cut'. A reflective surface, such as aluminum reflective duct tape, could reflect the intense beam away.
As I watched the portion using the 'rover', again, I think you might have some success, by mounting two lasers, pointing down, and using mirrors to 'double-cut', at the same height, a photo-eye, could be used to advance the rover forward, if nothing is breaking the light of the photo eye, and stopping/slowing down, in front of the cutting lasers.
35 years ago, it was just a thought, but with today's technology, I'm surprised no one has capitalized on this kind of 'green(er) energy' advantage. Keep up the good work.
Those reflections could sear your retina, and at a decent distance. Lawsuits are why this isn't a thing.
Some friends and I tried this years ago. Didn't work well - it only cut grass very slowly because it took so long to boil off the water content. Also we has three friends and only two pairs of safety glasses, so one of us had to sit behind a wall and look at it through a camera. I caught a reflection off the grass for a moment, and sometimes when I look at the sky I can still see the retinal scar.

Dang man, stinks that such a simple small mistake can have such an impact.
@@m.i.c.h.o I mean no. Natural selection. Its just stupid to play with it.
I love your ideas. I am a gardener with a degree in engineering. A mower needs to be able to keep a lawn trimmed approx. every 2 weeks. Concentrate on trimming a lawn rather than clearing a jungle and you should have less issues with grass falling in front of the laser. Consider having the lasers underneath the vehicle body between the axles. You can point a series of lasers across to lenses and mirrors on the other side of the undercarriage to improve efficiency and safety.
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.
Possible improvement idea: put a laser rangefinder on it and have it adjust focal point of the laser based on distance. That way you can mow anything at any distance.
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?
Alan Pan sent me!
😂
same!
Same
The pan/tilt version scorching plywood really suggests that this is half way to being a functional if not practical large format laser engraver, to do murals and stuff; depending mainly on what other materials it can scorch. I have to wonder how hard it would be to motorize your columnating lens system to move the convergence point in order to maintain focus on a plane, then add some kind of system to measure the distance and relative orientation of a wall; and of course some code to the controller to vary brightness based on a jpg, png, svg, etc. Finally you build a 3 walled tent out of laser curtains.
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
I was left speechless at the sheer amount of awesome engineering you threw at a comical idea and actually made it work. Great video!

:D
Version 1.1- ditch the laser, go with the magnifying glass concept as demonstrated early on. Get larger & more lenses, use camera lenses to control focal point. Prisms can help aiming. Run the rover off solar. Sunlight can be far more powerful than those 40w lasers, just needs concentrator.
Parabolic Lensinator9000
Sunlight here in the pacific northwest is a bit hard to come by except in june, july and August.
@@Blaiz3d don't forget the way to obvious "self destruct" button
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!
I purchased a goat for $40 and have not had to do my lawns for over 4 years.
You should hang the laser on three steel wires, so it maneuver freely in 3D space without needing a vehicle. The wires can carry the power (by using an insulated transformer you can safely use AC power) here. Just add a spindle with the laser on the bottom. :)
For safety reasons, you can add a 24 GHz radar to detect humans, so it would zip up out of the way as soon as a human steps into the garden and continue work if you're gone again.
As a kid I always imagined like a big laser grid that came out of the ground (kind of like a sprinkler) and then would cut your grass. The only problem with this is your lawn has to be level and I was worried about if it came on and someone was standing in the yard, so it would have to scan your yard first before cutting. But great vid!
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?"

I have always wanted to cut the grass with a laser too
The problem is tall grass. Mow the grass first, then use this to keep it trimmed at 1/8 or 1/4 inch clippings so they fall back into the grass, and it might work great at maintaining a large area. Might need a much more powerful laser, and then encased in a safety cutting head/shield like a mowing deck. Someone would end up lighting the neighborhood on fire though.
Allen Brought me here.
I could see this rover -or perhaps just an array of stationary housings, being used to maintain a topiary hedge with absolute perfection. Amazing skill set you're developing and demonstrating with these projects!
I think a tattoo removal laser or other very short pulse, high intensity blasting laser would be more effective here. As it will explode the grass rather than burning it, which is vastly more efficient.
Though I guess it will also emit broadband light from the million degree plasma fireballs it generates, which will include UVC and X-ray radiation, as well as just being incredibly intense even through any eye protection out there (and obviously *blasting* the retina or lens with such a laser directly would be blinding).
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.

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.
It's been said here atleast 500 times but I'm going to extend that respect and admiration a bit further in saying. This was awesome to see and watch, and I'm impressed that this worked on the level it did. We are still a bit away from doing this efficiently but to see it happen at all is awe inspiring. Keep it up, I can wait to see you up there with StyroPyro and IDidAThing.

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.
@4:40, you can see the plants doing their circular dance. So cool!
This is so heavily overengineered it weirdly pains and satisfys me at the same time. Love it
4:47 That one flower that tried to grow at just the wrong time
I feel like it would take me 5 years to complete all the projects you did in this one video. Would be cool to install in a mower deck lined with mirrors around the inside and have cycles of solar charge then cut and repeat. :)
Or maybe lenses and mirrors to directly use the sunlight?

At 3:59 we can see how reliably your accelerometer works to shut down the laser if anything happens to it…
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)
This is the most awesome "I was too busy to mow my lawn" excuse ever!
I would like to see gamma ray snow removal next.
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
I love how you can watch some of the grass grow in the time lapse while the laser is cutting.... awesome project!
1:00 you should have used a lens with an electronic focus. You could have then just had it static and cut the whole lawn from one place. You could have made it really fancy and used a range finder to calculate the focal distance!

I think a 30W CW CO2 laser would work well, as it's wavelength has a high absorbance in water. You would probably have to put a front coated mirror on the stepper motor mount, rather than move the laser as they are bulky. The only issue is they tend to have a larger output beam and therefore a shorter focal length, but this could be altered automatically by adding another focal lens and moving it along the axis of the beam.
@@miggelie someone tried that. not accurate enough
Allen Pan brought me here
This would be a great solution for the elimination of grass and weeds that grow between the pavers on my driveway and pathway around the house. The set up would have to be vertical with a short focal length. The "carriage" could be an electric (chorded) lawn mower.

@@paradisepipeco most mag(a)-ots wouldn't know a laser if it blinded them...
I got an idea that mimics hair cutting, that might improve this lawn mower:
1) It could grab a chunk of plants in front of it, I imagine something bending down from the top in front of the rover.
2) The mechanism has flattened the grabbed plants at the point where it should cut.
3) Laser at the flattened point (from side to side as it does now). The laser should focus at the distance where the plants are held.
4) Drive some centimeters forward and repeat.
I just love how inefficient this is. Using 1000x the energy to mow 1/8 the area of a gas mower
..because....laser....LASER..
Not to forget the noise it makes at the end...
better off torching your lawn with a flame thrower
Yes but this could be adapted cut weeds on very rocky terrain, I have 30 acres and often think if I could do something like this during winter when the grass is wet
@@scottstewart9154 no, that would be a bad idea. This laser is so dangerous that refections off a rock can blind before the eye can close.
3:35 Imagine these set up everywhere with sprinklers. Beautiful.
Something to consider is how often do you have to mow with a laser as opposed to a regular mower, maybe the 'cooking' has an added benefit of less mowing. The grass is cooked and since plants tend to grow from the top, might be worth the effort/danger.
@@manuelh.4147 duh
Yeah it gives you a backyard of brown dead grass.

The amount of work that went into this video deserves more then just a like!

for the impeller put a air filter from a car inbefore it, and use a blower for it instead of a turob impeller. Its going to be much simpler and still produce the same air pressure, and remove the two varying openings, those varying openings actually create a air raid siren effect(change in pressure creating noise) probably would be a better design.
Well this makes me a lot less afraid of laser weapons, but being instantly blinded doesn't sound fun either.
This is one of the coolest videos I've seen in ages

Nice to see you're slowly turning into Styropyro
as a kid who grew up mowing our lawn in the 90s, this is exactly the device i was dreaming of and my father said would never exist haha
look up Husqvarna automower
Great idea rctestflight. I just mowed my pasture with an analog scythe that I had to sharpen every five minutes. An attached, automatic laser sharpener would have helped greatly!
Bro imagine this design being amplified and improved upon. You’d have a real world application for this (if you don’t mind your lawn smelling like burnt grass of course). Genius! Excellent work!
It's still a high power laser so it really depends on what you want to do with it. Lasers with accessible beams are not very good for consumer products :D
This could only be made better if you made it look like a shark with a freekin’ laser on its head!
Doofensmirtz moment
If he does that, he will be 100billion dollars richer !
I need this for my lawn. I haven't mowed in a year, so the grass is going to be super tall and dry in the summer. Great idea. I can turn it on in the center of the field and go to the store
this was quite a fun adventure! Now I want a lawn in a grid with lasers on the end so it just automatically cuts the whole square/rectangle (like with your Al frame but for the entire yard) then you don't need a small thing moving! And your power is built in!

Finally someone with an example...I've been looking for this test on youtube for 4 years...They have these laser contraptions to clean off rust from metals and very precise. But mowing a lawn with lasers should cut down the timing
I was recommended this by another crazy person making a grass laser
For a while I thought of a similar thing, but powered by concentrated sunlight. Instead of 40W, you'd have up to a kilowatt and it's free energy (when the sun shines). A TV fresnel lense should do the trick, if you don't want to play with mirrors.
Even cheaper solution: An insulated box with no bottom and a double glazed top. It'll cook the grass alright.
why not do it then?
That's how they destroy weeds.
I’ve had this idea for many years - thanks for the content and time / effort. Great job.
Love the combination of several projects. Awesome work. Also thanks for reminding me to get a new laser module.
How about making a Lawnmower that uses water pressure to cut the grass?
It would be safer to by passers than a laser, and it would water the lawn as well!
Always a pleasure to watch a genius visionary at work!! I foresee one small problem - if it takes several days to mow one strip, isn't the grass going to grow quicker than that on the rest of the garden, before you get to it? Sort of like using a spoon to bale out a sinking boat? But nothing like that at all, obviously!
the idea i had was that instead of blades in a normal lawn mower, its replaced with laser, that way it can be a very powerful laser and its enclosed in the body of a normal lawn mower so there's no exposed laser. maybe it will be 3 rows like a face razor so it cuts the grass 3 times in 1 pass. that way you get a 'blade' that never dulls in a lawn mower.
but that requires physical effort
that’s genius
@@dtbkdn you can still set it up the same on an automation silly
Laser diode would still need to be replaced
Also with mirrors to bounce it in almost a plane of laser. Or maybe a lense to make it into a line
Having mown lawns with reel mowers (Dad's "influence" about 60 years ago) to all kinds of rotary mowers, and lawn tractors/mowers, I believe the number one tip to a good looking lawn is DON'T GO SO FAST. The faster you go the less time the blades have to cut each inch of direction, the lawn is bumpy- the less time the wheels of the cutting machine have to adjust to the topography, and the less time there is for "averaging" the height (i.e. a deep cut could possibly have been not so apparent had the machine moved slower thereby allowing gradual cuts leading up to the deep cut and away from the deep cut). I didn't go slow, but I didn't race either (2/3 of an acre at my house, a girlfriend's 2 acre lot). Want a good-looking lawn? Slow down. OR, tell your lawn maintenance people to slow down when cutting the grass.
thanks internet dad. i appreciate you.
(no this isn't a joke, i genuinely mean that. i grew up with an alchoholic father that never taught me anything. never even bothered to teach me the importance of brushing my teeth as a kid.)
Agree 100%. It also gives the grasshoppers and other bugs more time to get out of the way. Easy does it.
ok boomer
Time is money for them, they aren't slowing down.
@@tonyprice2256 yea,let's protect the largest destroyer of agriculture on the planet.
I had visions of “Oops, I cut the neighor’s head off”.
It would’ve worked well on Collins hair 😂
This is unbelievable engineering that is well above my education, but I enjoy watching. Thanks.
You should try it again with a pulsed laser. You could get much higher momentary power to really blast through the grass instead of just heating it gently.
If you motorize the lens, you can change the focal distance of the beam as well, allowing you to optimize it for how far you're trying to cut
2:54 soooo now all cats in your neighbourhood are probably blind
This is so brilliant! Thanks for posting. Let me know when you go into production I will get one. You are my kind of people.
Incredible. I'm constantly astonished by your ingenuity.
Version 2: Same big laser with a variable focal range lens and a radar (or similar) ranging sensor so it can tell when the grass has been cut and automatically adjust focal range accordingly.
and perhaps also add a fumes sensor, and a mobile phone board to call the firemen if we accidentally burn up the field 😅
Nice job! Can I suggest that the laser needs to be arranged with a lens which produces its focal point close to the cutting line so that it then disperses to harmless strength soon thereafter. So Laser-Diverge lens - Concentrator lens with focus at the cut line, and thence divergence to nothing. That will give maximum cut power on the cut line (using the left-right-left rig), and safe power beyond. To get an acceptable cut rate in the centimetre per second range you need to really max the cut power.
Holy shit, I've yearned for laser lawn cutting since I was 13 years old and shoving a mower around my dad's yard under the hot summer sun.
Great job!
You might be more effective with a CO2 laser tube (IR) and cut in a more focused patch of grass with the rover. It would also help if there was some sort of leveling mechanism so it stays at a certain height above the ground.
Great. With an invisible laser the first sign that it is on is your fingers falling off.
Are you Mitch Taylor from Real Genius!?! Use Liquid Nitrogen! ... btw.. Jordan is into you!
@@navarredr It's yet another in a long series of diversions in an attempt to avoid responsibility.
If your budget allows, you could try one of those 2000w laser cleaners that they use for stripping rust off of metal. That would cut super fast!
The reason the vacuum turbine is so loud, is you essentially made a very inefficient mechanical siren. If you look up how a tornado siren works, you'll see what I mean
7:30 "But what if you don't want any grass at all and would rather burn everything?" "That's why I invented the lighter"
This idea can be improved with an autofocused sensor to get data at the nearest piece of grass, and adjust the focus of the lens to send the focal point of the beam to that piece of grass. You could seriously improve the speed this way.
Or put it on a tracked rc and front cam for predictive auto leveling
My favorite part is how you can see the rest of the lawn just growing taller while the laser is working
i like how lasers have been futuristic for atleast 50 years now
I know right? Didn't they start doing sci-fi laser blasters in the 50s or something?
@@TheConjurersTower That would make it 60 years!

@rctestflight. The key is to mount it in the mower under the deck. But close off the hole for clipped grass. Line the inside of the deck with mirrors. Then use it
I just wanna say for the record, I thought of this prolly 20-25 years ago. I'm glad I get to see someone had the same crazy idea and brought it to fruition. My only major negative thoughts that held me back from doing this was the ground would have to be fairly flat throughout the landscaped area.
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!
I haven’t watched this video yet. But I thought of this over 30 years ago. My idea was a retractable mirror on the edge of your grass and the laser would rotate, hit the mirror and bounce around. But with the mirror fully surrounding the entire yard, the laser wouldn’t cut anything else but grass
i thought the same but with the underside of the deck being mirrored
I think the logical next step is to build a lawn mower that magnifies the sun's rays into a solar laser. You'd have to make it to automatically adjust the angle based on the sun's movements, but I think it could be done
I'm planing to build a solar cutter, but I don't have the money to buy what I need now. I don't think laser this powerful should be in the wild without proper care, this 130w alone can blind animals that looked at it (birds, etc) since it was running for so much time.
You can can focus the sun's rays fairly cheaply by taking apart an old DLP TV that no one wants anymore and getting the gigantic fresnel lenses that are in them. They focus the suns rays very well and you can burn through a lot. It would be too big to mount to a mower, but could be on a stand that rotates.
The rc lawnmower was cute af
you could stationary mount your laser vertically pointing at a spinning mirror in like a push mower deck with a reflective surface around the outer perimeter of that deck so you get multiple cuts out of one beam as it is reflected. putting the laser in a housing cuts down the safety issues and lets you optimize your laser power to cut distance. great build
I like that idea. Add in a fan to move the debris and it could probably work similar to a traditional mower.... But with singed grass blades and a horrible smoke smell.
What about using a big lens mounted on a sun tracker to focus sunlight and a mirror/prism set on servos to orient it?
In fact, you could also add a small Stirling engine to the mix to make it solar but not photovoltaic powered!
It would only work when there is enough sunlight, so it will need to pause when there isn't enough, but it will give enough time for the battery to recharge and keep going for a while!
You could also go all crazy and use the excess energy to build up air pressure and release an occasional blow to push the grass away, it would be much quieter (as it would only be from time to time) and perhaps more effective than vacuuming.
For a totally overdoit project, you could add LIDAR to detect where the grass need to be cut.
RC, this is a great idea. Have you considered using the large array laser with a collimator? There are specific lenses for higher energy use cases. Also, if you got a fiber, you could get things more flexible. With a collimator setup, you can extend the effective focal length by having a smaller emission source to focus from. Wider doesn't do much as the ability for the material to shed the heat wasn't being overwhelmed in a timely fashion.
Focusing the higher power array should substantially improve cutting and make the mower capable of cutting a lawn in a reasonable amount of time.
you thought a regular lawn mover blade was to much hassle well now you can have a lawn cutting laser🤣🤣🤣
There is a point where you say “basically turning up the sun” got me thinking, could you focus the sun to do the cutting? Would there be a consistent way to direct sunlight (provided it wasn’t cloudy) using gimbals and servos and light sensors to make this device use solar power? Could you build basically a “Lawner Rover”?
11:19 when you break a leaf in Minecraft
I think what this needs is a pairing of some way to find the distance of the focal point and a way to adjust the beam dynamically so that point changes, that way the point with the most powerful cutting potential can always be directly on the thing being cut.
A motor to turn the old camera lens' focus over time
I had this exact idea in 2010. All my friends were like "Oh that will start a fire". Anyway, I guess I'm glad to see it's an experiment and not some product someone made a million dollars on.
6:47 That might actually be better. If the beam is hot enough to cook but not hot enough to cut, then it's below the temperature to start fire and, if continuous, eventually the shifting and rain, and sprinkler or whatever will cause the cooked parts to just sink into the grass and help fertilize it.
13:49 My idea never had a vacuum setup to suck up the grass. My idea was basically an arch with multi axis wheels on each end and the beam would bounce between mirrors at the base of the arch hundreds or thousands of times before it is directed into a diffuser (either a patch of white paint or a small glass sphere).
POS comment, You had an idea but never did squat with it. So, big whoop. I had the same idea for an awesome time machine but never got around to building it. 🙄
Great video and now you are the Laser Cutting Lawnmower Man.
