If that is the case then you should take a look at Electric Ink for creating cheap circuits. In fact you can make your own Electric Ink using a process which is quite simple. The good folks at the  <a href=\"http:\/\/www.popsci.com\/stir-electric-ink-cheap-circuits\">Popular Science<\/a> site have provided us with an instruction guide that I am reproducing here so that I don&#8217;t loose the instructions in case PopSci decides to reorg their site:<\/p>\n<p><b>Materials:<\/b><\/p>\n<ul>\n<li>Powdered graphite<\/li>\n<li>White vinegar<\/li>\n<li>Syringe<\/li>\n<li>Elmer&#8217;s clear glue (I think any clear glue should work)<\/li>\n<\/ul>\n<p><b>Instructions<\/b><\/p>\n<ul>\n<li>To make the ink, put powdered graphite in a cup, cover with vinegar, and stir. Let it sit for a few minutes.<\/li>\n<li>Once the graphite settles on the bottom of the cup, remove the clear liquid on top with a syringe.<\/li>\n<li>Stir in about a teaspoon of glue to keep the graphite suspended. A thick line of paint has a resistance of a few kilohms per inch.<\/li>\n<li>Draw the circuit, wait for it to dry and then you can test it out.<\/li>\n<\/ul>\n<p>I was wondering if this would work on T-Shirts, under a laminate or other such protective coating to prevent the circuit from getting washed out. Maybe I should try this out over the weekend on one of my old T-Shirts. Wonder what kinds of design&#8217;s I would be able to make before hitting issues if this works. <\/p>\n<p>&#8211; Suramya<\/p>\n","protected":false},"excerpt":{"rendered":"<p>At times using wires in a project might not be the most practical option because of space\/weight limitations.
