This was in the wrong archive so i reposted it - here is the recipe:
1,000 - 1,500 mL water - depending which version you make
300g Graphite
100g Gum Arabic
3mL Glycerine
1mL Oil of Cloves or 5mL Listerine
Hope you find it useful

This premise is being used in a new manner, in aircraft control systems that don't use wiring harnesses, but rather different voltages with different frequencies, in order to control servo actuated motors and so on. All these feature are incorporated within the skins and frames of several advanced weapons platforms. But Robs video show the simplicity of new emerging tech.
Yes your ink is by far the best!!! I have made my own and then I bought your ink.. Your older ink was not a large amount better than what I made.. But then you upgraded your ink and now it is incredibly AWESOME there is no other ink that compares to yours!
Thanks Robert, I always look forward to your videos. As far as the preservative goes, I 've had good results with 50 ppm colloidal silver.
Great stuff Rob. Happy New Year to you, your family and also to Luke and his family! Nice to see this. I may actually have these ingredients! Now, the best thing I can make that I'll use? That is what I'll study on.
Love it, Jules Verne taught me that trick in the book I read as a child entitled "the mysterious island". I believe it was captain Harding that disassembled his pocket watch and use the crystal to make a water Lens. thank you Robert, I so enjoy your videos
I love it! OIL OF CLOVES 🤪 THAT WILL BE STABLE WHEN THE PYRAMIDS ARE FLAT
Nice tipping in the wet binder grinder facile expression ........ lol love your videos ! Rob keep up the great work ! Thank God for Rob !
The ink on his hand makes this even more legit
The way you are making conductive ink is the same as when I make watercolors, and you gave me a great idea which is to try a wet grinder. So far I have been using a mortar and it is hard on the wrist!
Glad you did this again Rob. I'm wondering if a magnetic stirrer would work in place of the wet grinder?
If you you have the time could you show the polyurethane version, I could work it out but your presentation and expertise would interesting
Thanks Robert.
An idea: screen print a pattern of oblongs of one ink on a sheet. Dry it and screen print an offset pattern of a different ink on top. Each oblong of the second ink will overlap two of the first ink areas. Result: a series circuit of many junctions between dissimilar conductors suitable for experiments with the Seebeck effect. - high voltage thermocouples - thermoelectric generation
Interesting
Could be used for as a the premise to create DEG (raindrop panels)
I am a bit of a watercolurist that also likes creating my own pigments. I was kind of hoping the lamp black I harvested recently was conductive, but apparently not. To give a go at the conductive ink I'll have to buy some powdered graphite or muck up a lot of pencils for the conductive ink, but sadly I will not be able to light up my paintings with my homemade black and greys.
Happy New Year y'all.
Is this a repost? Well worth the re-watch....
The paint thickness meter is amazing..
Rob,
Thank you for all of the unbelievably valuable info you have shared over the years.
Where can I find the "schematic" for the printed pattern that will serve as the most conductive/productive atmospheric energy "siphon"?
I remember watching your video from a while ago where you showed the high accumulation of this power using the graphene ink. I am wondering if you have found any more conductive ink patterns since, and or if you have come across anything else worth noting since.
I would be willing to pay for such info and recently emailed your site. Thanks.
Hi Robert! Need your help! I'm looking for an affordable way to coat a mosquito net with highly conductive ink layer so the fabric becomes conductive and can be used as a faraday cage... I'm totally lost on how to go about this most efficiency as graphene is extremely expensive here in mexico. You are the only person I know of that is likely to have an answer to this. Thanks so much i love your show! 🙏💙
Sap from a tree, cooked, may provide a waterproof surface. My thoughts are making a conductive trace on stone or on a protected log.
Happy new years 💫
Hi! Nice formula. Thanks to share it.
Best wishes my friend.😉
it was like over half a decade ago the last time ive seen you make conductive ink! it looks like you looked up some conventional ink-making practices, we used the same kind of spice grinder to make linotype inks in school
yeah, id forgot about hot linotype, updated for a diy desktop plus (additive) wand electroplating can become the diy (till roll sized) roll to roll pilot line/test production line with working end products useable for shed power walls etc as apposed to expensive commercial end product.
Awesome, unlike my first day or 2022. 10 day course of antibiotics. Hopefully start feeling better in a day or two
Ask your pharmacist about supplementing between doses with probiotics to replenish tummy flora that also gets wiped out :) If they didn't already mention or you didn't already know, of course.
@@SaltyShaman Thanks for the advice, it's been years since I've had antibiotics so I will most definitely ask tomorrow and get some. You would think it would be a mandatory course of action for a pharmacist to advice. Thanks for your time.
Very nice video!!! Would you mind telling me the model of the paint thickness meter?Thanks in advance!!!
Could you do a video making transparent conductive polyurethane?
Nice video on conductive ink. True different binders can be used for waterproof such as PU binders!
Hi, if i want to use a waterproof binder such as polyurethane (varnish), does that mean that the carrier must be waterproof also (eg. organic solvents)?
@@nanatv1507 Yes all carrier must be waterproof.
What would be the best way to bind one or more batteries to a printed configuration of this ink? Would one solder them?
Dear Rob, I have made my own windgenerator but it won't turning in the wind anyhow. Can I send you a small video of it zo you can give my some advises tot get him turning?
Can this method be used for heating pads??? Thinking of sandwiching it between two silicone placemats and under the desk!!!
Great idea, Robert! Although I have a question about increasing the conductivity of the graphite: would adding iron powder increase the conductivity? I hope you can answer this for me because I cannot do the experiments myself. Thanks in advance.🤪
I would like to purchase from you if can be shipped to mexico for a reasonable price. But i am also trying to figure out if this ink will stick to / impregnante the mosquito net fabric (hence making it conductive for emf shielding) and how to go about it in the most effective manner (dunk/spray/paint)...? Thanks so much!!!
could you use acrylic medium instead of water and gum arabic?
You really need to use carbon black to get below 10 ohms on a thin layer. Graphite just can't do that . Ketjen 600 I think we used
Would graphene be a replacement for graphite or as a additive for more power?
Can this ink be used in a printer .could you print a coil for a motor
I think a rock tumbler would work well and be esier to get (also useful for other things)
Graphite is manufactured in two main types, Synthetic and Natural ,is there any preference in your opinion
I baked some anthracite coal in a zero oxygen chamber for a few hours and I now measure 1.5 Ohms across its 2 inch diameter! Before baking it measured in the Mega ohms range!
You graphitized it . Well done . I did that with a pillow full of feathers
Hi, does the type of graphite mater? I see natural, synthetic, and just plain old graphite for sale. For example, fascinating epoxies inc. pure graphite powder 44 micron quart size. Or even the stuff in pencils?
Respectfully
Where on earth did you get that monster of a grinder Robert ????? I've never seen anything like it before ....
Can we make using combination of chemicals, combining wet alkaline compound from 1.5v cell and lithium from lithium cell , add epoxy or acrylic or any other glue, I think conductivity improves.
I'm thinking like a super capacitor for high voltage. Like a super laden jar.
What is the best way to get this onto aluminum foil?
hello Robert, roughly how much power can you get out of an A4 sized sheet of paper covered in your conductive ink?
I have been looking for a way to measure the thickness of my conductive ink. Could you please tell me where I can buy a paint thickness meter? There are multiple types out there. Can all meters measure conductive inks? What specific type should I buy?
Does the grinder also make the graphite particles finer and thereby affect reduce the resistance compared to just mixing or blending?
How would expanded graphite powder perform compared to graphite?
Do you really want per mil, i.e. an imperial measurement? Surely per um / micrometre or mm / millimetre would be more useful? As the SI units of resistivity are Ω⋅m (Ohm metres), and the SI units of conductivity are S/m (Siemens per metre) metres would be best. In SI units this ink is 1.21 mΩ⋅m or or 826 S/m. Your ink would be 49 uΩ⋅m or 20.4 kS/m in SI units.
Will conductive carbon ink eject electrons when exposed to light? Can you paint a layer, insulating layer, and another layer, and produce solar energy?
I noticed that the ink consistency is very liquid... and I need a heavier ink consistency... because I will use it for silk screen printing …. Will increasing the percentage of gum arabic make the consistency heavier without affecting the conductivity of the ink?
How long does this ink remain usable? Does its conductivity decrease with tim?
Does it off has when heated
is your workingink website coming back sometime? it appears to be down.
how to repair carbon contact on laptop keyboard frc connector
Yea!
i'm waiting transparent conductive material for next projects
Maybe add salt to the mix to boost conductivity.
Nice Rob Cheers! Can it be made to be less resistive than copper wire?
The short answer is "no" because, other than super conductors and silver, copper is the best conductor we know of. Carbon is not a bad conductor but not a patch on copper.
If you use a thicker ink (paint), then the resistance will decrease but you will not get (for a given cross section) a better conductor than copper.
BUT - the same can be done with air float copper and silver, but I am not sure who to suggest you make these without using fairly hazardous chemicals (mostly nitric acid).
Arguably - you could make colloidal silver - let the generator run indefinately and then evaporate away the excess water - and then add to a binder as the video
I don't want to suggest how to process silver with nitric acid on someone elses video channels BUT if you are interested and search for how to refine silver, it is when you then precipitate out the silver by adding strips of copper that you get "silver foam / silver fluff / silver sponge" which is incredibly fine silver powder. You can then ALSO use clean iron and do the same again to remove the COPPER from the solution - you now have ultra fine copper powder too - which again can be used to make conductive paints.
Commercial silver loaded paint is goppingly expensive - more than pure silver usually gram for gram - but home made can work extremely well and be (somewhat) more modestly priced.
Most carbon conductive paint is really aimed at fairly modest current handling (LED's sensors etc) rather than trying to replace copper wire that needs to handle serious power.
I want to see a new style high voltage dry pile battery, that could be charged with a vandegraff machine.
Great video’s. Does anyone know how I could become a member as the link doesn’t work for me.
Use desktop browser.
Hallo i am living in germany i want to make myself pleas what is ingridien thank,s
If you put the ink plastic and ran copper wires in parallel lines would that make a solar panel
Add some junction, please :)
Look at all the perovskites papers; in model measure, ok, then add the magic to keep it lasting long enough to be sold :) This is the point where the papers get fuzzy not to tell too much and where it starts looking like alchemy.
Hi I have been having vision of a zero point car with something that looks like plates at the bottom of car it has a purple light and it also makes cat float , I don’t know much about physics or Astronomics but I am getting images of what it may look like . I also see these plates charging homes for lighting . I am trying to visualize a 3D printer that gets charged by a zpg coil plate do u see what I mean can we talk so I can describe to u what I see
Was thinking about doing lead acid battery with stainless steel and carbon fiber.can it be used on both ends and would you have to use a different acid ??
see his older lead acid video's
You mean negative and positive plates when you say 'both ends' ? The carbon on positive plates may get oxidised to co2 after some charge cycles .
@@michaelcorbidge7914 like how many charges before it stops working thank y
It'd be less than ten charges. I've watched heaps of his videos and still stuff in my memory about lead acid . Negative plate is fine but positive is no go for carbon . Question arises then does a carbon electrode during hydrolysis for hydrogen production also if used get slowly oxidised . Carbon rods are always the immediate items to use as electodes and we never think more about it.
@@michaelcorbidge7914 thank you
When using varnish do you have to add anything else
depends on how fluid it becomes after you have added all the ingredients you want to try.. adding varnish thinners like generic white spirits (mineral spirits) or turpentine as a solvent reducer before you start might work better for extending the cure time in air
@@paulmaydaynight9925 thank you
What else you would need to mix in if you'd want to make it a solar panel? Also need to add a separator film I gather?
Fuckin love you man. You make my ADHD seem calm by comparison lol
Apparently Cod Liver Oil helps with ADHD, i know cause i tried it lol
Also,I called companies and talk to one engineer who said it was hard to sell,printed solar panels,a company in Finland printed on rolls of plastic,but no one would buy it,smells like they didn't advertise, just think though,we could print a million feet long away and 60" wide ,that's so much 365 million feet a year,on one press
as i recall they ,like the uk roll to roll plastic gfx display companies over priced their product to industry only not one off retail per batch made & so you cant get a4 screens or plastic pv on mass for cheap as per the initial premise today.

your books were helpful but VIDEO would be exciting coz , there is "RMS" additive 😀
What about mixing in powdered copper? Yourr ink would be far more conductive obviously, but is there a downside?
give it a go. diy wet ball milling any copper2 should do ,photonic sintering copper/ali oxide with a light 3d printer etc could produce fine detail's too perhaps if you can find the right light freqencies -or just blitz it with pulsed lime light, spock 'Operation Annihilate!' style lol-
I tried making this with Varnish... I think neither Varnish nor the Graphite dissolved properly in water
How did it come out?
@@154g it's conducting all right. After drying, its not at all flexible. Very brittle, if I touch it, black powder falls off. Perhaps I should try a different brand of Varnish, so that its not so brittle
new year google recommendation
Why does my mind automatically go to things like. I wonder if it could be used to run a flash light or torch? Sorry.
Could you use it to detonate small explosives? Or can I use it to refill my printer cartridges. LOL 😆
"It's not a waterproof binder"
Does regular air humidity dissolve the connection over a few months?
While mother may be a bit peeved at you using waterbased ink in her spice grinder, at least you could clean it! I suspect using a polyurethane binder ink would be to enter divorce territory! :)
I am having a de'javue. It may be the effect of my kill shot.
🙏👍🙏
But how to make conductive milk ?
see his older milk + tea based plastic's video's :P
Hey Rob, would PVA glue work as well? Because I don't have gum Arabic. But I have a bucket of PVA glue left over as binder🤔
Have you tried other conductive media? I been browsing ebay and it got my creative juices flowing lol
