Circuit Scribe Workbook

As PhD Students, we know the value of open content. That's why our workbook is accessible online for free. Print out as many copies as you like, modify and share. We'll also post additional project plans as we develop them.

Open Source Hardware

As current/former PhD students, we're passionate about teaching and sharing how we do things. To that end all of our electronic modules source file are available for viewing and modification. We proudly have the OSH (Open Source Hardware) logo on every module. Even before we launched our Kickstarter in November 2013 we showed off Circuit Scribe to the folks at Open Source Hardware Summit at MIT in September, 2013.

Not only are our magnetic modules open, but our original ink formulation has been well documented in both academic journals and a video. Below Analisa walks through the steps of formulating the ink. You can find more information in the journal article:

Our Materials Safety Data Sheet (MSDS)

Material safety is of key importance to us, and the Circuit Scribe system hinges on our formula being non-toxic. Our conductive silver ink formulation has been tested and certified non-toxic by Duke toxicology in association with WIMA, the Writing Instrument Manufacturers Association. While there is no specific minimum age for our pen alone, we do recommend 8+ or adult supervision. If Circuit Scribe ink gets on the skin, simply wash it off.

Warning about OTHER silver inks

There are a few other conductive ink pens on the market, and a subset of those involve silver nanoparticles. We've dealt with silver nanoparticles for the original ink formulation of ours during Kickstarter, but being a consumer product it was very important to eliminate toxic formulations and nanoparticles are a nonstarter.

There are a few products that we are giving warnings to their use for consumer applications, or mixed use with our modules and silver nanoparticle inks. Ink made by Mitsubishi Paper Mills, such as that found in their "Circuitry Marker," also believed to be similar to AgIC's formula, IS considered toxic.
