DIY Conductive Paint: Good Idea on Paper
July 24th, 2014
Conductive paint or conductive ink is lets you draw conductive traces, great for simple projects, mockups or even minor electronic repairs. You can easily order these materials from different manufacturers – such as Bare Conductive – but if you want to save money check out Brian McEvoy’s simple guide to making your own conductive paint.
Brian suggests using graphite powder as the conductor and acrylic paint as the medium. In his brief tests, he found that acrylic paint was a better medium compared to Elmer’s glue and Titebond wood glue. The acrylic paint and graphite powder mixture even appeared to have a higher conductivity than Wire Glue, which is a popular conductive paint brand. Head to Instructables to see a brief summary of Brian’s tests. You can also read the unabridged version of his experiment on his blog.
