This article and video shows you that the was of making graphite conductive paint at home. It is very easy.
The objective of this investigation was to endeavor to locate an other option to industrially accessible conductive paint. It is mind blowing stuff however costly. I've perused different Instructables like Makerboat's $1 Conductive Ink and IceCats' Paper Electronics. They helped me touch base at my own particular formula, which utilizes just two fixings however I think my testing is more solid.

To influence the triumphant formula you to require:
Graphite powder*
Acrylic paint
A container with a water/air proof seal
To finish each test you require:
Elmer's Glue-All
Titebond III Wood Glue
Acrylic paint
Wire Glue (tm)
Graphite powder
4 wooden toothpicks
4 containers with water/air proof seals
Paper
Ohmmeter
2 zip ties
*Be watchful with graphite powder since inward breath can prompt respiratory issues.
Stage 1: Glue-All and Graphite Sample
For the main formula graphite powder was blended with Elmer's Glue-All until the point that the consistency was spreadable. Be cautious while including the paste since pressing the jug will shoot an impact of air into the container and graphite powder will blow all over. The third picture represents this.
The proportion was:
2 sections Elmer's Glue-All
1 section graphite powder
The outcome was liquid yet thick. It could in any case be utilized as a cement.
Two lines were drawn with the toothpick. One thin line and one thick line. The toothpick was wiped off in favor of the container and permitted to dry alongside the lines.
Stage 2: Titebond III and Graphite Sample
The second formula was Titebond III and graphite powder.
The proportion was :
1 section Titebond III
1 section graphite powder
The outcome was liquid yet not runny.
Two lines were drawn with the toothpick. One thin line and one thick line. The toothpick was wiped off in favor of the container and permitted to dry by the lines.
Stage 3: Acrylic Paint and Graphite Sample
The third formula was acrylic paint and graphite powder.
The proportion was:
1 section acrylic paint
1 section graphite powder
The outcome was marginally thicker than paint.
Some graphite conductive paints are not really work. There are some reasons for that.
Two lines were drawn with the toothpick. One thin line and one thick line. The toothpick was wiped off in favor of the jug and permitted to dry alongside the lines.
Stage 4: Control Sample With Wire Glue (tm)
The fourth example was industrially accessible Wire Glue (tm) from Think Geek. The Wire Glue(tm) should have been blended so another toothpick was utilized.
The Wire Glue(tm) was significantly runnier than alternate examples so the lines were not as cumbersome. Less material being put down means a higher protection since there is less carbon/graphite for conduction.
Two lines were drawn with the toothpick. One thin line and one thick line. The toothpick was wiped off in favor of the jug and permitted to dry alongside the lines.
Stage 5: Preparation for Testing
Every one of the specimens dried for five hours and were marked.
Shut everything down were taken to demonstrate the thickness of each example. All together they are:
Elmer's Glue-All
Titebond III
Acrylic paint
Wire Glue(tm)
To guarantee the examples were tried consistently two zip ties were fixed around ohmmeter test tests. This guaranteed the test tips were a similar separation for each test.
Stage 6: Testing Elmer's Glue-All and Graphite
Each specimen of Elmer's Glue-All and graphite was tried with the settled width tests and recorded.
Stage 7: Testing Titebond III and Graphite
Each example of Titebond III and graphite was tried with the settled width tests and recorded.
Stage 8: Testing Acrylic Paint and Graphite
Each example of acrylic paint and graphite was tried with the settled width tests and recorded.
Stage 9: Testing Wire Glue(tm)
Each specimen of Wire Glue(tm) was tried with the settled width tests and recorded.
Stage 10: Results
The acrylic paint is the most conductive material in this specimen set when painted with a toothpick. The materials are normally accessible and cheaply. The acrylic paint cost $0.78 and the graphite powder cost $0.75. All costs are in US Dollars.
The benefit of the Wire Glue(tm), which has the following most astounding conductivity, is that it has a lower consistency so it could conceivably be utilized with custom pen nibs. Locally acquired pen nibs were utilized with the Wire Glue(tm) in an alternate test yet it was badly arranged to apply.

This fabricate took me two days and one more to compose these guidelines.
I run a blog where I speak perpetually about the things I assemble, including an unedited adaptation of this undertaking with recordings that demonstrate the thickness of the examples. There are other flawless things there like a gadget that gives you a chance to hear temperatures and a console you can use from inside your pockets.
