A major goal of Public Laboratory is to produce simple and easy guides to construct many of our low-cost tools. Here are some of the illustrated guides, tutorials, and other supporting materials we've put together so far:

Illustrated Guides

• http://grassrootsmapping.org/guide - Our first illustrated guide attempts to thoroughly explain how to construct and use a balloon mapping kit.
• Making a spectrometer: plots-spectrometer-guide.pdf (17.4mb), plots-spectrometer-guide-small.pdf (4.3kb)

In progress

We're constantly improving and exploring new ways of documenting and disseminating our designs. Here are some prototypes and planning pages:

• T-shirt guide - A t-shirt with instructions for balloon mapping printed on it.
