DIY Conductive Paint for Makey Makey or Bare Conductive

Conductive Paint Results and Links
Great Link to the differences between Makey Makey and Bare Conductive Touch Board: www.bareconductive.com/wp-con...
Bare Conductive Paint 10ml for $12: amzn.to/2T8qfEJ
Powdered Graphite 1lb for $14: amzn.to/2WdAxWk
Elmers Glue 1lb for $14: amzn.to/2Mqj8oA
Test Results:
Acrylic (plastic paint): Graphite by weight
10:1 = failure
3:1 = success (moderate)
2:1 = success *Paint became too thick
Tempera (water based paint) : Graphite by weight
10:1 = failure
4:1 = failure
3:1 = success (moderate) *surface is dusty and releases graphite
Glue : Graphite by weight
3:1 = success *slightly dusty surface but best overall medium to carry the graphite (most consistent results with varied application)

Thanks Bro 🙏🏻🙏🏻 this is a lab level experiment with data, you aren't any less of a scientist! 😀

Thanks for the demo and ratio of Elmers to graphite. Just what I needed.

[@keithjonas3257]

Well I think I made the mistake of purchasing a Graphite "mixture" that includes mineral ash and quartz. I did the 3:1 (Elmers to graphite "mixture"), and I got ZERO conductivity; according to my multimeter. Warning to others, to read past the marketing cr*p when purchasing your graphite.

Prueba con aporte de Sal de mesa/cocina para mejorar la conductividad. La tinta China, India o similar a base de agua y negro carbón también debiera funcionar mezclada con Grafito por su excelente propiedad de conductividad.
Gracias por su aporte, saludos cordiales desde Argentina 🇦🇷👋

Good explanation maybe if they want to add water they would have to make it more conductive maybe adding salt or vinegar if not the best option is to buy graphene and make the same mixture and it will be obtained I think I have a greater conduction I think that in these paintings it is in 1 m no I remember it well, with carbon it would also work but at low conductivity, although you could measure the piece of carbon, you are measuring its surface inside it, maybe the continuity is very random

What if we use acetone together with glue and graphite??

Thank you for your video! Inspire me a lot to experiment with my makey makey... but I didn't understand if you added water to your mix or not. Doesn't work with other relation like 4:1 ?

[@danielaktas4105]

I did not add water to any of the experiments. In my classroom, I encourage my students to add a little water to make the paint apply easier but explain that they have to do more coats of the conductive paint to make a functioning painted circuit. The lowest graphite ratio by weight I was able to sorta get working was 3:1 acrylic to graphite but I found using 2:1 acrylic to graphite was the best working ratio.

@@danielaktas4105 I just try with 3:1 glue to graphite and works very well. I tried before with vinyl glue but didn't work (probably vinyl glue isn't a good conductive fluid), then i have decided to try with transparent liquid glue and it works perfect! Obviously without water in mix. I think also it will be good to use carbon powder, because is cheapest than graphite. Take a look to this video: ruclips.net/video/W_ouYLeIkoo/видео.html

Nope, no water added
