There are rather small lasers available. Some are considerably smaller than an average sized 3d printer. For cutting I suggest a CO2 laser which are the big ones but for engraving or making graphene I’d suggest a diode laser with an overkill power rating run at low power for longevity. I don’t have any hands on experience with diodes but the main complaint I would have I think is the diodes burning out or losing power pretty quickly if you run them at high power.
Graphene is one of those mesmerizing things. Theoretically you could also dope graphene this way as well. You just need to submerse the kapton tape in less than a millimeters depth in deionized water and add drops of your phosphorus or boron source in the areas you need them.
Thank you so very much for the migraine I have now got due to overthinking!!😳 Also perhaps the fact that I'm as thick as pig-poop has occurred to me yet again?!!🤔 I'm off to feel rather stupid, but I am grateful for folks like you, who have fantastic minds and more importantly,,, know how to think for themselves!!👋😁 Namasté 🙏💞 Mr and Mrs Dingbatt.😎👍👍

@@ThinkingandTinkering I can hardly wait! Bit cruel to show us the lazer and the kapton tape, and then not fire it up. ;) Like MC and many others, batteries/graphine is what got me started on your channel. Glad to see you circling back.
Glad to see some additional references to graphene! It's one of the things that got me hooked on the channel. I've gone through all the old content I could find and can't seem to find 2 videos where you used a couple of different mills to separate graphite flakes into graphene. One was using a vertical ball mill made from a repurposed variable speed drill, marbles, graphite, glycerine, and urrea. The other was using some sort of high end spice mill which had stone rollers in it instead of blades to do the same thing - again - using glycerine and urrea as the sticky substance to exfoliate the graphite layers. I'm hoping they aren't lost forever. What I was most interested in was the ratio of urrea to glycerine. I think I recall the basic design features of the apparatus well enough. Any help or pointers from you (or someone else in the community!) would be greatly appreciated. Keep up the great work, I always look forward to your videos.
Very interesting video as always. I am very pleased that you are now using a lapel microphone. You sound GREAT! I would struggle to hear you before this. It will be great when they can harness some of the hundreds and maybe thousands of uses for graphene, especially for battery charging and storage as well as making buildings and bridges stronger.
Nice to see you doing stuff on Graphene again. This is what I watch your channel for Graphene and batteries. What’s your thoughts on LTO batteries and were do you think Graphene will play with batteries.
I've watched all the videos Rob but putting it like you're right lol you have given us everything we need to know. Ya follow a line of thought or interest and often forget to go back and follow the avenues that also interested you lol down the rabbit hole but forget to climb far enough out so to speak. Thanks for the reminder :)
Graphene has the same strength-enhancing effect if mixed with two-part Epoxys. A little goes a long way and would be a much better application for small quantities of graphene!
20 Years ago I always thought science-fiction was unhinged with lasers that could grow stuff or on-demand printing objects and I thought a future with such creations would never come to be. Now we're here.
honestly Robert Your an amazing smart man and i would of been honored to have you a a teacher / tutor at uni or college they way you speak so passionately about your work and how its fascinates you its an inspirational , honestly Robert you should think about getting paid to be a teacher people like yourself need to be in the schools because the passion you have and how you describe your work and findings is just brilliant and spectacular , just makes me feel the passion and the excitement and why i love technology and how stuff works and is made , you Sir are a Brilliant inspiring man
Thank you so much for that. I can't tell you how much that makes my life easier.. Though most of my experiments have been theoretical, thus far. This will allow me to put skin on the bones so to speak. This will help me in my personal research very much.🎉
My 3d printer has an option to add a 3.5W laser engraver (diode type). Would this work? Thinking the 3d printer could use gcode to make capacitors/batteries by using alternative layers of kapstan tape that have/haven't been lasered to graphene. There are also more powerful laser attachments (5, 10, 15W), would these be too powerful? (As higher power laser is better for laser cutting applications). Great stuff Robert!
Once I have my laser I plan on testing this. I want to scrape the graphene off and use it as an additive to UV cured resins and print with it. Planning on doing strength tests and seeing if it is a viable means of producing strong parts with no additional manufacturing steps (such as casting the parts from metal).
Question: If you use a laser to scribe graphene onto paper... How do you get it off the paper? Just a scraper and hope? Or is it better to burn it? Is it better to light flash something like glass and scrape with say a Stanley knife blade?
I had a go of this back in 2017 with one of those cheap Neje laser engravers. I had a few issues with it looking stripey and not getting good conductivity. I should revisit it again. Not sure what the electrolyte for it should have been either.
And, it occurs to me, that it could be automated with a disc of borosilicate glass, pierced with holes, and fed/indexed with conductors. Similar process to the continuous seam welders used in cans and pipe welding, and double-action die-presses.
Late to the party here, but it occurred to me that another application for this would be making DIY flexible circuit boards from scribed Kapton tape. Likely ultra-cheap too, since you're only paying for a bit of tape and the power necessary to run the laser. Heck, multilayer circuit boards would be trivial since you could just tape the stuff to itself after it's been scribed. I'll have to see if there's a tool library nearby when I can get my hands on a laser cutter like this so I can try it out.
When I used to work at Braman BMW, a car dealership, We used to scan papers all day long and I would clean the glass and the rollers and there would always be these flakes of carbon left over. Most of it was residue is from the toner, but I never got a chance to test it’s electrical conductivity or resistance. Some of it Was Reflective Almost Like Foil And That Got Me Thinking I know it sounds crazy, but scanning paper like that, might actually be the best way to test graphene, or flash it. Basically scanning material with a thin layer of carbon. Am I close? You could also put it in a wax and essentially let it dry and bake all day. Like the scanner. The more you use it, the more it deposits, the more it protects. To a point I had to scrape it off after a while. My guess it does that on the microscopic level but you can’t see it. It’s only one percent. I know each car isn’t a sheet of paper, but the graphing is already in the wax. I used to scan mountains of paper every day , and after a year or so, I got that.
If I remember right with the flash method as well, to get even slightly reasonable yields you would also need to do it in a rarefied, preferably inert atmosphere. The laser flashing method seems better for large scale production, as you can literally run it down a processing line with several laser heads.
Yes Rob, but what about the actual physicality of doing anything with homemade graphene? For instance, how would we use the graphene that we made from paper, to make a type of shield, or to strengthen concrete, or make graphene components?
Hi Rob, thanks for the video - nice to have graphene back in the channel. Does the laser need to have any special specs? Could you please guide us a bit on how to select a suitable laser for such an application? Thanks!
That's good to know. I was seriously considering building the Rice method flash graphene. The capacitor bank at 200v is very scary. And also it requires a vacuum chamber. Those aren't cheap either.
Had similar thoughts. And the process of changing the small tubes is decently time intensive. It's nice that anything carbon based can be used, but what the heck kind of value am I getting by needing it to fit into this tiny tube? Has to be a better way of scaling up
@@sanaru02 This is by far the easiest, safest, and cheapest method of producing graphene flakes. This would be perfect for strengthening concrete or epoxy, but I dunno about using it for batteries. The protein might hinder its conductivity.
@@WTF_BBQ Definitely. And for sure, filtering that out, if needed, seems like a bit more difficult than the video suggests, meaning that more precise uses (such as batteries) might be a little tricky unless you have a reliable way of filtration and liquid removal.
Have you made a video on the kapton + laser method Robert? I've had a search of your videos and didn't find one, although I did find about 15 more I'll be watching this weekend that look quite good pertaining to graphene and supercap production. Please drop me a link if you have, I own 6 lasers from 5w up to 100w and am quite interested in this process you speak of.
Hmmmm... haven't got a laser...how about using the sun (when it shines that is) and a focus lens, or even several of them, one should be able to make light graphene on big sheets pretty quickly?
Maybe the graphene coated tape could be used to make a flexible solar concentrator (like in the graphene parabolic mirror video) that could be rolled up like an awning when in storage. Would be a great way to heat a Stirling engine if it works.
Could the 'flash' be augmented/replaced by lower-voltage/high-current from a welding transformer? A brief high voltage pulse could trigger the discharge, similar to the old style camera flash bulbs etc. Choose the timing to trigger the pulse at peak a-c voltage, it should have some serious clout. Any thoughts?
Tech Ingredients channel explained it. It will not work, because the crucial thing in this method is time. Energy must be delivered very quickly followed by a quick cooling. That's why those supercaps are needed for this method. AFAIK slower heating rate produced just normal graphite.
@@ThinkingandTinkering Hahaha, He makes cool experiments, lot of science, some things go BOOM, it's educational and entertaining. His channel is a bit more chemistry focused i think. And a bit more lab equipment is needed. So for most of us tinkerers it may be interesting, but out of reach 😉 He makes a good booze in his reflux still though😆
hI professor it is nice video.i want to know if i can make flash graphene with 220V AC(it is korean domestic electricity.) my circuit is just comprised of 1 switch 1 power supply(it is just domestic socket) 1 glass pipe and a copper electrode. do u think i can do that? Thx for nice video
That's cool Robert, it would be nice to have a machine that can interchange 3D printing, CNC, and a lazer powerful enough to cut at least 1/4" plate steel even thicker would be even better. Do you have to have something in addition to your Elegoo 3D printer to cure the plastic or just the printer and the filament? Thanks and thanks for the video too.
So could you potentially architect a battery that has an internal super capacitor as a core and then use a separator to distance to battery from the super capacitor to provide a composite form that can do the work of both charging and delivery?
Mate you forgotten about Ultrasonic Exfoliation of Micronized Graphite... 2 Minutes per Batch.. You can Nebulise the Excess water and Put a Binder to it like Liquid Cellulose... For transportation...or.. different Thingys.
@@christiankrippenstapel4336 graphene is natural and is found in nature. It's already in our bodies. It's in whiskey barrels and whiskey since whiskey became a drink in barrels. Jim Tour has more about it.
it's always a delight to see your work! i have questions about lightscribe graphene; is the precursor really graphene oxide? and if we print the entire possible surface of a dvd to make a supercapacitor: what would be its capacity in Volts and mAh? what you are doing is great, thank you
0.02% to increase strength by 35%? Thats 1/5,000! What is the mechanism that imparts such strength to concrete? How far can you push the amount until its peak or diminishing returns? I've been experimenting with expanded polystyrene granules in cement, any increase in the matrix would be very welcome.
Check Tech Ingredients channel. He did flash graphene with supercapacitors and then mixed it with epoxy resin. He made tests on rods. Amount of force needed to bend the rod with graphene was incredible.
@@ThinkingandTinkeringFor some bizarre reason Google Translate has decided to write this as 35%Death, Lol,lol lol 😆 I suspect it is because I have a problem, even changing a lightbulb,let alone trying to make Graphene!! Lol!😅
I ended up in the hospital 3 times over a polystyrene incident. While sleeping, I reached on the floor next to my bed where I was working on a project, picked up a piece of 1/4"x 1/4" polystyrene about the length of a pencil and swallowed it. No surgery ended up being required, but it took 2 weeks to finally pass.
thanks for the video. i am trying to reproduce the results on polyimide tape with 450nm diode laser (cheap and easily available), however instead of getting the graphene, i either burn the film completely or do not get any conductivity at all. i am experimenting with scan speed between 10mm/s and 100mm/s (the highest i can get from the CNC setup i have and power from 1W to 3W (the max i can get in my laser). could you advise what might seem to be the issue pleasse?
I asked in many places, but got no answer. Searched for it too. What will happen when during and accident or during the handling, small pieces of carbon fiber or graphene enter the body, lungs, stomach and even blood stream? I mean, mechanically - wouldn't it damage tissues and cell walls, and be very hard to remove from the body? Only thing i found is kevlar fibers cut tissues of the human body when a bullet manages to pass through an armor vest. I searched and found nothing. I guess not many want to talk about failing armor vests and crashing carbon fiber cars. In other areas the damage of other fibers is acknowledged and people talk about it. Maybe i just don't know the exact key words to search for it...
Good to see graphene doing another comeback on the channel mate... I know it's really your passion and field of expertise amongst others. Would love to see some practical home uses for graphene in action. I know there's more than a few from years ago, but I suspect with a larger audience now, and the huge improvement in video quality (not to distract from the originals of course), more practical applications of graphene would be very welcome by many.
The best, most cost-effective way is to make graphene from trash. I understand you’re dealing with some scary high electricity, but essentially it’s turning trash or recycling centers into Foundries. The Energy Economics are the same. Just scale and implementation is different (Flash, laser induced, exfoliated, and other chemical methods) The only thing is you can’t just plug into an outlet. You Need Clean Energy in order to make graphene. And the best way is with solar, wind, and wave power, stored in hydrogen or in capacitors
So, it would technically be possible to light flash graphene bare 3d printed parts to create high efficiency circuits on them? This deserves to be tested! Also with that tape, graphene magnetic coils!
@@ThinkingandTinkering I see your point. Maybe something on bioplastics or geopolymers that the graphene could be added to? Like making a cellulose plastic from paper, and seeing how graphene improves it's ability to withstand higher temps. Might lead to a castable low temp Stirling?
Wondering about graphene as an additive to the epoxy used in laying up fiber & resin Boat Hulls... sounds like one would be lasering for a year+ to obtain enough graphene to make a difference in hull strength... say a 12 meter hull. Anyone out there who has added graphene to epoxy?
Tech Ingredients did a video showing their version of the capacitor formed graphene. The really cool part was they took it and mixed it into resin and measured the resin strain and strength performance under load to fail.
Dr Tour did an even more in depth version of this that is an online seminar for the really interested - for those that don't know - Dr Tour is the guy who invented this method

@@ThinkingandTinkering how is the flash of light any different than burning it? Or is that essentially what we are doing? And if that's the case, couldn't we use any material as just about anyting turns to carbon when it's burned if I'm not mistaken
The diode laser can be very dangerous please remember use eye protection This comment should not be necessary but to many people don’t think about PPE when using this type of machine.
Will you be restocking Graphene (and ink) on your Working Ink webstore, or have you stopped with the store altogether, as I don't notice any products in stock lol
Well isn’t this interesting. Does that mean you can laser print graphene? In something like a fdm process? If this is so? then full graphene prints are are available for 3D printing purposes. I once joked about using graphene in tattoos and reconnective medicine. Being able to fix nerve and spinal cord issues. Maybe even fix motor neurones? Is seen someone reference a exo skeleton using graphene? Don’t know how true that is. But if so you have mobility aids. ballistic protection. countless other uses. In not too much a leap to get layers of nanotubes using a laser. Still want to spell laser with a z. But that something else. Graphene is being eyed for the next gen of solar cells if it can produce spike structures? The it likely to be multispectral? Working in a broad range of wavelengths. So it might just work at night? Even off the cosmic background radiation….? With regard to solar cell. It can make then just Nm is thickness. So it could be possible to etch it into glass? Maybe as a primary coating? I don’t know how much that would cost? But if you can make it? You could end up with graphene reinforced glass? Which would be excellent space flight materials?

Tech Ingredients channel explained it. It will not work, because the crucial thing in this method is time. Energy must be delivered very quickly followed by a quick cooling. That's why those supercaps are needed for this method.
AFAIK slower heating rate produced just normal graphite.
are you taking money from tech ingredients to promote his channel lol - try reading some actual research mate
no mate it can't
@@ThinkingandTinkering Hahaha, He makes cool experiments, lot of science, some things go BOOM, it's educational and entertaining. His channel is a bit more chemistry focused i think. And a bit more lab equipment is needed. So for most of us tinkerers it may be interesting, but out of reach 😉
He makes a good booze in his reflux still though😆
@@ogi22 thanks
Could you not source capacitors from old Tig Welding(HeliArc) rigs? My old Miller has 4- 450v 2F Capacitors the size beer cans.
yeah i suppose you could if you wanted - never thought about it - cheers mate - still doesn't remove the danger though lol
@@ThinkingandTinkering Fair enough. Just defers the cost of killing one’s self. Thanks for all of your great videos.
hI professor it is nice video.i want to know if i can make flash graphene with 220V AC(it is korean domestic electricity.) my circuit is just comprised of 1 switch 1 power supply(it is just domestic socket) 1 glass pipe and a copper electrode. do u think i can do that? Thx for nice video
Lol, I just bought a 3D printer and now I want one of these!😅
lol
@@ThinkingandTinkering I will enroll in your membership soon. I have got 5/6 weeks before my Elegoo printer arrives.
Graphene is cool.
it is
Well it conducts thermal energy really well, so it can be quite cool or quite hot depending...
Interesting indeed.
That's cool Robert, it would be nice to have a machine that can interchange 3D printing, CNC, and a lazer powerful enough to cut at least 1/4" plate steel even thicker would be even better. Do you have to have something in addition to your Elegoo 3D printer to cure the plastic or just the printer and the filament? Thanks and thanks for the video too.
Have a look at "MPCNC" (Mostly Printed CNC) - it's not the only design out there by far, but I built one and love it.
just the printer and filament mate
@@ThinkingandTinkering Thanks Robert.
So could you potentially architect a battery that has an internal super capacitor as a core and then use a separator to distance to battery from the super capacitor to provide a composite form that can do the work of both charging and delivery?
Stickie fingers and a 5 finger discount 😂
yeah i suppose lol
Can you upscale the production by lightly sanding a lasered piece of carbon paper with super fine sandpaper? I need some to increase cement strength.
you will like the video i just posted mate
Mate you forgotten about Ultrasonic Exfoliation of Micronized Graphite...
2 Minutes per Batch..
You can Nebulise the Excess water and Put a Binder to it like Liquid Cellulose...
For transportation...or.. different Thingys.
no - i didn't - i just didn't mention it because there was no need to
He covered that eons ago in one of his videos I believe
Great again! 👍
Graphene is impressively versatile - but is there any information about its toxicity in terms of handling and disposal?
@@christiankrippenstapel4336 graphene is natural and is found in nature. It's already in our bodies. It's in whiskey barrels and whiskey since whiskey became a drink in barrels. Jim Tour has more about it.
Very fascinating. Thank you for making the video. Maybe you could actually make 10 farad Kapton tape capacitor on video? Would be interesting.
I have already done it mate - some of the clips in this vid were clips of my older vids
@@ThinkingandTinkering 10 Farads from Kapton already? What's the link!
Interesting .. thanks Robert for sharing that bit! 🙂 I wonder if we could inject a bit into our veins .. we might last longer too! lol 🤣
lol - sshhh - isn't there a conspiracy theory on that?
it's always a delight to see your work!
i have questions about lightscribe graphene; is the precursor really graphene oxide?
and if we print the entire possible surface of a dvd to make a supercapacitor: what would be its capacity in Volts and mAh?
what you are doing is great, thank you
0.02% to increase strength by 35%? Thats 1/5,000! What is the mechanism that imparts such strength to concrete? How far can you push the amount until its peak or diminishing returns?
I've been experimenting with expanded polystyrene granules in cement, any increase in the matrix would be very welcome.
Check Tech Ingredients channel. He did flash graphene with supercapacitors and then mixed it with epoxy resin. He made tests on rods. Amount of force needed to bend the rod with graphene was incredible.
35% mate
or watch the original Tour seminar!
@@ThinkingandTinkeringFor some bizarre reason Google Translate
has decided to write this as 35%Death, Lol,lol lol 😆
I suspect it is because I have a problem, even changing a lightbulb,let alone trying to make Graphene!! Lol!😅
I ended up in the hospital 3 times over a polystyrene incident. While sleeping, I reached on the floor next to my bed where I was working on a project, picked up a piece of 1/4"x 1/4" polystyrene about the length of a pencil and swallowed it. No surgery ended up being required, but it took 2 weeks to finally pass.
thanks for the video. i am trying to reproduce the results on polyimide tape with 450nm diode laser (cheap and easily available), however instead of getting the graphene, i either burn the film completely or do not get any conductivity at all. i am experimenting with scan speed between 10mm/s and 100mm/s (the highest i can get from the CNC setup i have and power from 1W to 3W (the max i can get in my laser). could you advise what might seem to be the issue pleasse?
I asked in many places, but got no answer. Searched for it too.
What will happen when during and accident or during the handling, small pieces of carbon fiber or graphene enter the body, lungs, stomach and even blood stream?
I mean, mechanically - wouldn't it damage tissues and cell walls, and be very hard to remove from the body?
Only thing i found is kevlar fibers cut tissues of the human body when a bullet manages to pass through an armor vest. I searched and found nothing. I guess not many want to talk about failing armor vests and crashing carbon fiber cars.
In other areas the damage of other fibers is acknowledged and people talk about it.
Maybe i just don't know the exact key words to search for it...
Good to see graphene doing another comeback on the channel mate... I know it's really your passion and field of expertise amongst others.
Would love to see some practical home uses for graphene in action. I know there's more than a few from years ago, but I suspect with a larger audience now, and the huge improvement in video quality (not to distract from the originals of course), more practical applications of graphene would be very welcome by many.
The best, most cost-effective way is to make graphene from trash.
I understand you’re dealing with some scary high electricity, but essentially it’s turning trash or recycling centers into Foundries.
The Energy Economics are the same. Just scale and implementation is different (Flash, laser induced, exfoliated, and other chemical methods)
The only thing is you can’t just plug into an outlet.
You Need Clean Energy in order to make graphene. And the best way is with solar, wind, and wave power, stored in hydrogen or in capacitors
Great video
Hi Robert, congratulations on the content! a question... is it possible to use ozone in graphite to obtain graphene?
So, it would technically be possible to light flash graphene bare 3d printed parts to create high efficiency circuits on them? This deserves to be tested! Also with that tape, graphene magnetic coils!
you should test it - it is possible - bu the devil will be in the details - of course
Dr is this the method used to make the tardis?
I've been reading the papers 120v works fine.
awesome - cheers mate
Will there be a more in depth video in the members area?
no more depth is needed mate - but i can try if you like - but it really will be a bit repetitive
@@ThinkingandTinkering I see your point. Maybe something on bioplastics or geopolymers that the graphene could be added to? Like making a cellulose plastic from paper, and seeing how graphene improves it's ability to withstand higher temps. Might lead to a castable low temp Stirling?
@@McRootbeer i like that mate - that extends it - thanks for the idea
1:39 "degrees Kelvin"? No, it's just "Kelvin".
Aw, and I still hasn't made a working stirling...
Wondering about graphene as an additive to the epoxy used in laying up fiber & resin Boat Hulls... sounds like one would be lasering for a year+ to obtain enough graphene to make a difference in hull strength... say a 12 meter hull. Anyone out there who has added graphene to epoxy?
Oh, I love your vids!
Stay put for other applications of laser now that Robert has a laser. BTW, is it a new acquisition ?
no mate i have had it for ages
Can I have the link to buy your book on conductive inks and a pint of your ink please
Tech Ingredients did a video showing their version of the capacitor formed graphene. The really cool part was they took it and mixed it into resin and measured the resin strain and strength performance under load to fail.
Degrees Kelvin is incorrect. Other than that great video!
Do you plan on making another video on this? I would love to see some experimentation and maybe experiment with it myself.
mate i have done hundreds of these videos and most of them are now in the members archive
Yeah, I was referring to this method of making graphene. I have watched a lot of your videos and I absolutely love them.
NOW ROB HOW FAR HAVE YOU CAME ALONG ON MAKING GRAPHENE now thats the interesting question i havent been on here in a while to watch been really busy
👍👍👍
And about making graphene using CD burners?
TechIngredients did a more in-depth version of this for those that are more interested, but this is still a great video.
Dr Tour did an even more in depth version of this that is an online seminar for the really interested - for those that don't know - Dr Tour is the guy who invented this method
I've cooked enough subwoofer voice coils to know kapton smells pretty rough when hot. Not quite as bad as old gear oil though.
show us how it is done, pls.
Alien Abduction
Nope,,, I have to admit that I have abducted Robert!!
But I plan to return him very soon!!
Just got a few projects to finish safely and then I shall send Robert home!!
I'm not doing anything "Misery" a la 'Stephen King',
because of all the work spent making the 'AI Robert',,,,
for the video uploads,
And the time and energy making cuppas for him.....😅
@@AndreaDingbatt they got him making battery`s i herd lol
@@overbuiltautomotive1299Lol 🤣 Good One, Thank you very Much for the Giggles😅 and Smile !!😁
Keep on telling folks that it's the Aliens, I have kept Robert for far too long,,,
So let's blame this on the Aliens,,,,
~until I have got Robert back home!!
TeeHehehee!!😅
😎👍👍
Could you do something like creating your graphene sheet battery with this that you hoped to power the Twizzy with?
Rob is missing...
yep
lol
Ooh. Ooh..wait ..what if you had a thin layer of sugar water plus you pre load it with graphene and then...you flash it. Wouldn't that be super easy to make giant shapes.
I didn't grasp the concept, laser hits the tape and graphene starts to grow?
Rob is missing!
the tape is carbonised then the carbon re-arranged to form graphene
@@undernetjackI have kidnapped Robert for making my new place Off -Grid!!
Don't worry, I will be sending Robert back home ASAP, because I am not doing anything "Misery" as in Stephen King!!
Basically,,,, due to the amount of time and work putting together an AI version of Robert in videos!!
It's also very hard work making cuppas for him, Lol lol lol 😆
@@ThinkingandTinkering how is the flash of light any different than burning it? Or is that essentially what we are doing? And if that's the case, couldn't we use any material as just about anyting turns to carbon when it's burned if I'm not mistaken
😀😀😀👍
cheers mate
I want to see someone make the capacitors to for flash graphene using the laser graphene lol.
Is it going to be the new asbestos?
The diode laser can be very dangerous please remember use eye protection This comment should not be necessary but to many people don’t think about PPE when using this type of machine.
yes they do - everyone thinks about it - and in case they don't there is always 20 or so reminders from folks
Will you be restocking Graphene (and ink) on your Working Ink webstore, or have you stopped with the store altogether, as I don't notice any products in stock lol
Well isn’t this interesting. Does that mean you can laser print graphene? In something like a fdm process? If this is so? then full graphene prints are are available for 3D printing purposes. I once joked about using graphene in tattoos and reconnective medicine. Being able to fix nerve and spinal cord issues. Maybe even fix motor neurones? Is seen someone reference a exo skeleton using graphene? Don’t know how true that is. But if so you have mobility aids. ballistic protection. countless other uses. In not too much a leap to get layers of nanotubes using a laser. Still want to spell laser with a z. But that something else. Graphene is being eyed for the next gen of solar cells if it can produce spike structures? The it likely to be multispectral? Working in a broad range of wavelengths. So it might just work at night? Even off the cosmic background radiation….? With regard to solar cell. It can make then just Nm is thickness. So it could be possible to etch it into glass? Maybe as a primary coating? I don’t know how much that would cost? But if you can make it? You could end up with graphene reinforced glass? Which would be excellent space flight materials?
Overload..😅
Did you see the Tech Ingredients video about this?
It was really good, although, not sure I'd be trying his method myself at home though 😅
no mate - I find him a bit boring and i went to the Dr Tour seminar - so from the horses mouth so to speak rather than a second hand version - I am actually a carbon chemist you know lol
@@ThinkingandTinkering If you aren't a researcher it's hard to know where to find good information, what works and what doesn't, what is nonsense... you and other channels are important because of it.
@@ThinkingandTinkering oh...didn't know that...and yes, I do find he can be somewhat dower in his presentation.
'Graphene' is - graphite. That's it. Everything else is just blah blah.
Where is Rob and what have you done with him?!
They have Rob under house arrest?
He made a bunch of videos to sneak off on Vacation?
Are you an AI generated Rob?
Why is the store out of graphene ink?
Channel got bought out by a large Corporation?!
WHAT has been going on HERE?
lolol - i come up clean once i have a bath mate lolol
