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.

Well Done! Clear Instructions and great narration. Thank you.

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.

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...

Too cool!! Thx. so much! This has got to be the coolest project EVER!

Thanks man, this amazing, just i need. regards from Centro America

Been looking for this for months! All I found was recipes with hard to get / toxic chemicals

Very cool tutorial, and professional video shot and edit skills shown! Thanks for t his great video

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.

Awesome! Thank you so much

Very good job...kudos to you

finaly something usefull thanks mate

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.

+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

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.

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.

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

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.
