- Turn fire into conductive ink and paint, then build electronic circuits, paper musical instruments and inputs for your Arduino boards!
Today you will learn how to make your own conductive ink to draw electronic circuits using the leftovers from your fireplace or BBQ! You can use this ink to draw circuits on paper and cardboard, learn about electronic circuits or play around with arduino boards like the Makey Makey to create paper musical instruments like pianos, digital drumsets, guitars, etc.
Conductive Ink is a great way to learn the basics of electronics. This a recipe that is non-toxic and extremely low cost. Comercial conductive inks cost around $10 to $15 for a small pen that may not last for much, specially if you want to draw large shapes or cover large surface areas.
This paint will just cost you cents to make using charcoil left from your fireplace or BBQ, a bit of black water paint and a bit of Elmer's glue! That's it!! The principle is that carbon dust is conductive so once you blend the charcoil from your fireplace and mix it with a bit of paint and glue you will have a paint that becomes conductive together with the carbon dust!
Now this is not as conductive as commercially available paints that use silver particles or industrial purified carbon, but it will be very useful to conduct very small currents, to turn on an LED or as inputs for Arduino boards. Please experiment with this and let's find out how to make this paint much more conductive with other ready available, cheap materials. Please email us at info@makerboat.com or visit us at www.makerboat.com if you have any suggestions. Let's create a Creative Commons, Open Source Conductive Paint!
Get a cookie tin or a cleaned out metal paint bucket, make a small carpenter nail sized hole in the lid put wood strips like Popsicle sticks or paper in. Close the lid put that on a fire for 15 minutes or more till the fire burns out. Inside will be charcoal perfect for your projects.
If you use 95% rubbing alcohol instead of water you can just let it evaporate away after blending and you will not get the mineral contaminates if you used tap water.
Or methanol.
shouldn´t the mineral contaminants be more preferable since they are conductive?
@@mrdonut7158 It depends on what they are some oxidize and so on it is best to know exactly what goes in so you can add as you need and control the whole process rather than a variable that can skew everything.
@@Barskor1 oh ok
material resistance is normalized to the length and cross-sectional area of measurement. The 'acceptable' chunks of charcoal might have had the same resistance as the rejected ones. If they truly do vary between chunks, then you need to measure with the same distance between probes.
Well Done! Clear Instructions and great narration. Thank you.
Its amazing what you can do when you put your mind to it. Safe and cheap enough for everyone to use/make. Great video my friend...
Been looking for this for months! All I found was recipes with hard to get / toxic chemicals
Lampblack for painters works also very nice. Does have a much lower Resistance in the 50 to 100 Ohm range ! Is much better than Charcoal ! Surely the silvery Graphite is still the best as it can go to around 10 to 20 Ohms this way, but it is more expensive and sometimes hard to get . You can also use big graphite Pencils for painters and blend them down. Measure the resistance before buying them with a digital Multimeter... If you only have charcoal, use the process as shown here, so you only take the better conductive parts and then you can also Hammer them into a rod in an iron tube and compress the powder very much and then heat it red hot glowing, that will also enhance conductivity... sometimes it is just okay to hammer it down and compress it very much...but with glowing it also red hot makes a real graphite out of it...but don´t let it completely burn, otherwise you will only have white ash left....After that you can grind it or blend it down again to powder and mix it with water and glue as it is shown in this video and then you have a nice much more conductive paint... or use the heated rods you made with it as electrodes for batteries...or press the powder into Plates for even higher surface battery or Supercap electrodes.... Hope this helps. Regards , Stefan.
Thanks for your advice. It really helps
grazie!!Where can I buy black smoke?LampBlack??
Uhhhh, when measuring resistance on multiple pieces you have to keep the probes the same distance apart. you keep measuring from the sides of different sized pieces. Sometime halving or doubling the distance from the previous measurement.
i have fixed remote controls by gluing onto the black rubber-graphite pad, a tiny small disc of aluminum foil, works perfectly
Is it possible to make carbon from plastic by pyrolyzing it instead of wood ? I think the carbon should be purer than carbon from wood, and so its conductivity should be better. What do you think about ?
Wonderful tutorial! I'm glad I found it. Thank you for making this.
Hi Debbie
Very cool tutorial, and professional video shot and edit skills shown! Thanks for t his great video
Outstanding video. Very easy to understand. I cannot wait to try this. Thank you for sharing.
Too cool!! Thx. so much! This has got to be the coolest project EVER!
To answer most peoples question. Once it dries. Its still conductive. This is what people use to copper plate flowers, plastic, paper. Things that are not conductive. I once copper plated a dollar bill
Well, good idea indeed. Thank you.Though ... why didn't you filter the mixture in a paper cone coffee filter ?
+Raoul Patakess Yes that should also be possible :) hadn´t thought about it
I seen in video,he use burn battery cell ,it has carbon powder.geaphite powder can be used instead charcoal or can be used mix.
Thanks so much! I cant wait to try this.
i wanted buy some ink on amazon for 10€, thank you for the video!
did it work ?!
poking around on the charcol will not tell you what is under the top layer.
its not going to be any sort of accurate way to judge its overall resistivity
Is activated charcoal from the pharmacy any good?
Thank you i found this video very informative.plz keep making such kind of videos
Thanks man, this amazing, just i need. regards from Centro America
thqnks
Can I use the graphite from carbon battery instead of using coal?
The resistance of graphite rode is very low (approximately 5 ohms )
+hazem zaqout you should try!! and let everyone know how it went! I also heard graphite is really good so it would be interesting to know if its very efficient in a home made ink
tanks!!
Using carbon from battery cell is too dangerous so be careful using it with bare hands
For musicians with very small hands, painting the keys with a smaller width while assuring less space between the keys will make playing the piano/keyboard an option. Smaller paintstrokes could make the biggest difference, especially to a child. What do you think?
Lovely ❤️
From India 🙏
I would of thought metal fillings would be best also I did not know wood or carbon was conductive learn new things every day hey wow great vid
If you have charcoal lying around could you just use that? instead of burning things?
+NJEnemy yes that would be useful, no need to burn wood, you can use charcoal for BBQ
@@bcnloft I've just tried BBQ charcoal (not bbq bricquettes, plain charcoal) and it is not conductive at all... Strange.
Chinese black ink is a good conductive ink ready to use ...
really??
Philoupaulo 62 damn lmao
Where can I buy Chinese black ink?
Does this flex with the paper? If this is flexible enough to not break when the paper flexes, you could do some interesting things with it. I'm imagining, for example... You could draw a circuit on the inside of a plastic sleeve for laminating paper, then once it's dry, run it through the machine to seal it. You would then have a thin, semi-flexible, waterproof circuit. To use it, just poke holes in the right spots, insert whatever, and maybe coat it with silicone sealant. You could, for example, attach a few LED's and the appropriate button batteries to make a decorative light for the front of a cap. ☺
Oh my God, God bless You so much
What is the biggest ohm level makey makey can still work with ? 300? 500? 1000?
I found this video for a science project, this really helped! And may I know what is carbon dust? Is this related to carbon black? Your response is very much appreciated thx
finaly something usefull thanks mate
Between charcoal and graphite/graphene, what is the most effective to make an ink for electroplating?
th-cam.com/video/GoqchqZfMCc/w-d-xo.html
what is the essence of making a conductive ink?
you are the best problem solver so pls one vdeo on how to make high bright lumilor as LG pannel light for oled.....
You might improve your chances of making your charcoal better conductive by limiting access to air. Wrap a dried block of wood in aluminum foil, better yet, fill a steel paint can and let it vent volitals, hydrogen, and carbon monoxides as the wood undergoes pyrolysis to charcoal. You need to ensure the fire heats the can long enough to complete the process.
i never knew a blender could run 5-10 minutes. informative & useful vid, thx.
sorry when I use graphite powder instead of coal and mixing it without blender, most of graphite are deposited. first I want to know does using blender has so much effect on depositing graphite or other allotropes of carbon ?
second is blender get completely clean after blending coal and water?
thank you so much.
What to add in the Conductive Ink so that it produces more heat (for a completely different application)?
Could you mix carbon and nickel conductive paint and get a good result?
and would this be good enough to electroplate plastic at 6volts? also what about adding fine powder graphite from a pencil into the mix?
Nice, thank
Can this ink be used to cut glass when microwaved? Great demo by Robert Murray-Smith shows how it can be done with a conductive ink with expensive ingredients in bulk. Im looking for a smaller, cheaper answer for cutting stained glass sheets for mosaics. Please let me know and thank you for the great tutorial
+steph c wow nice idea! I just don´t know really, its something you could try, I imagine the commercial ink works because it heats up with the microwave over, maybe because the silver and shiny objects react with microwaves (I know they can create sparks) but dont know if charcoal would react the same way as silver ink
Which glue should i use? Does solvent-containing glue work or shout it be a water-soluble glue?
Would this ink be a good solution to fix key contacts on rubber buttons for, say, Tv remote controllers or synthesizer keyboards? I am looking for a solution for that, actually. Thanks for the video!!
what dose the resistance measure out at when painted on somthing?
yups im waiting for that too
Doesn't mention the real part of the experiment
Nice video, very educational.Can I any charcoal..? :D
For anyone who play guitar. Can I use this as an alternative for shielding paint.?
tell me too if you got the answer for shielding paint.
Thanks i will make it too
Your background music is also the same one used in the mobile game, Astro Party?
Awesome! Thank you so much
can i use this ink to paint a baby bootie and then copper coat it with electrolysis?
for how much time does the product last ? and is there a way to concerve it please ?
You know that you can just crush the charcoal first, then wet it with water right? I mean, i don't wanna have some charcoal remains in my juice blender
Can we do a coating on glass slide instead of paper? Let me know asap thanks!
Such a great DIY - Bare Conductive is overpriced and has far too high resistance. Bravo! Question - is acrylic paint ok or would watercolor work better? Not sure what you mean by "Water paint."
Hi, very good explanation. Have one question: at 5.17 you do something in the carbon paint. It has a red thing to close it. I cannot hear what you are saying. Can you give the name of it please?
It's actually at 3:25. It is water-based glue.
Can it be used on membrane broken track
Professional video. What is name of the music playing in background?
okay so i have two questions that I'd like answered. first is would this work on any surface like glass, wood, plaster, ext.? second is i have charcoal art pencils, could i just draw with those and make a circuit or do i need all the extra stuff? please answer as soon as possible!
Why does he have to answer you. Are you paying him? LOL.
Alright ToxicJuice let me break it down for you, I've got a question I need to answer right now. What type of art do you make with your charcoal pencils. Get back to me asap!
What type of fart after eating the charcoal pencils. Get back to Michael asap.
(michael lennon) I draw pretty much almost anything from fantasy, to realistic, to anime, and even sometimes gothic horror. I just draw and enjoy it so really there is no specific type of art that I dislike or like more than the others. Now I have a question for you, why is it that you wanted to know what type of art I draw?
ToxicJuice I'm an art aficionado and was made curious by your post but I have another question that you need to answer right now! Where can we see some of your art online? Get back to me as soon as you see this!
thanks friend
can i use this as an electrical tape or as a traction tire for my train model?
this is so awesome
too much sulphur
can we have have the same results with the graphite in a pencil?
I want to learn electronics could recommend me a book to start?, something easy like electronics for dummies
Khan Academy has courses in electronics.
can this be used as "wire glue" as well? i am wanting to use SMD LEDs in an iron man arc reactor but solder irons could possibly damage the components because im not skilled at that level of precision work.
+James Bryan Hi James, it would be cool if you can try it out, but hopefully with cheap components in case you ruin something, also in case you need a lot of current, this ink has a lot of resistance, as long as you apply a low current nothing should happen except that its not as conductive as commercial silver based ink
Awesome 👍
Thank you
White glue colour should be used or not ?
With out battery it will work or not
excuse me sir, is the conductive ink that you make waterproof?
Bro your the best xxx
what is u use at minute 3:10 and what is the glur is the paper glue?
I want to learn basic of electronic
great vid
Does the paint works at 230volts current
Can i use graphite powder from pencil lead instead of charcoal powder??
Thanks Sead!!
awesome thanks
I already made it, but what kind of glue that i can use for pcb, it can't stick at pcb. Answer pleasee
Have you tried cyanoacrylate or super glue the slower curing type applied first not blended with the powdered conductive charcoal. Then before it dries shake the conductive dust over the glue from a salt shaker. I would think creating rust powder from a steel wool pad,or copper chore boy dampened with vinegar then dried and pulled apart and mixed with the chared dust would improve conductivity. One might also give clear nail polish a try using the paint and shake method.
what if you add salt, acid, cooper or aluminium in powder or limejuice??
+Carlos Herrera you should try, and find out.
is that a regulation size cooper or a mini cooper?
Marvin Cooper lolol
Now that wud be a lemonade, add some ice too....
excelent!!! gracias
is color necessary?
ink is needed or only glue is ok?
BETTER THEN BLENDER upload.wikimedia.org/wikipedia/commons/a/af/White-Mortar-and-Pestle.jpg
does anybody know is this worth trying on a keyboard membrane. ofc i would process it much more and make it finer
Yeah i want to know too... i want to try it on a ds4 controller
@@tushiwarashi I was thinking that myself. The problem with using that kids ink is that it's very flakey. You would want something that has a resin quality to it, not dry and brittle (for use in keyboards). They say also if it flakes it can come off and short other circuits nearby.
i have graphite powder how to mix that with liquid and what the good liquid for it is?
Use just enough water to make a paste. They won't mix without surfactant, so for every 1tsp of water, add a few drops of dish soap. Then thin it out with a very small amount of paint or glue and add alcohol if you need to thin it out further. This will also speed up the drying process. Then, brush it onto the surface you desire and let dry.
Where do you get the code from the last circuit?
what kind of glue did u use?
we can use a lead of pen pencilof a pencil
Would this work for fixing broken traces on a circuit board for a digital watch? Anyone tried something like that before?
great project. just thinking about maybe using colloidal silver as part of your mixture might increase your conductivity. There are tons of vids on how to make it cheaply and easily. Just use it instead of ordinary water.
Cheers
I try to make this ink a lot of kinds of glue but I see that it can not make electricially conductive. I've used silver and activated carbon. So please tell me how can you achive this conductivitiy via glue?
Did you try clear, water based glue? Did you test the conductivity of charcoal before blending? Did you check the conductivity of the mix before adding glue? It could be that the pieces of charcoal you used were not burnt enough and the quantity of the carbon element is not large, did you used wooden charcoal? In many countries there is stone charcoal which pretty sure won't work with the blender :)
Active carbon and silver is good conductive materials which I've used. I've used silicone and super glue as adhasive. I've added metals as high capacity. However after glue is dried since surface of this paste is glue this paste does not becomes conductive. I wonder how can achive this conductive ink as video. It's impossible since surface of paste is polymer!
Activated carbon resistance is 30ohm.cm. I've used White glue which is water based. Final mixture is 200-300 kohm.cm. However this paste is not well. I want to use liqud silicone. How can I achive this issue?
+fatih atatug i don't think super glue works, probably silicon either, the ink worked very well with clear, transparent water based glue as shown in the video, probably both super glue and silicon have chemicals that create a structure that is very resistant to electricity, like polymers that are completely non conductive, sorry
In Industry it's sold RTV electrically conductive silicone with using active carbon. How can they make I can not understand.
Can i use indian glue colour?
Anybody knows what is the name of the thing in the end? The thing like a piano, I need do something like that but I don't know how is called. Thanks!
makey makey is the thing at the end if that is what you are talking about
U want a cheaper one u can use an old keybord chip but the makey chip is more visuable and easyer
Very interesting 🤔
Could I make crude wire by impregnating string with this ink?
Theoretically, yes. But don't expect it to carry more then a few mA, and it will crack often.
can we use pencil graphite insteasd of charcoal?
yes, any conductive material will do. Graphite can give thinner conductive tracks. Read up on graphene when you can.
BuT wHaT AboUt GraPHiTe?!?!?!
Great video though, graphite would increase the conductivity.
how to check the resistivity of charcoal...
+aniket riguvanshi You need a multimeter to measure the resistance in ohms, it should be fairly easy to find a multimeter wherever you live, its a toold many electricians would use and now you can buy one for a few dollars anywhere
you can add some salt to give more conducive Power
