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](/tool/balloon-mapping) kit.
* Making a [spectrometer](/tool/spectrometer): 
  * [plots-spectrometer-guide.pdf](http://publiclaboratory.org/downloads/plots-spectrometer-guide.pdf) (17.4mb)
  * [plots-spectrometer-guide-small.pdf](http://publiclaboratory.org/downloads/plots-spectrometer-guide-small.pdf) (4.3kb)
  * [Parts and Crafts](http://partsandcrafts.org/) revised spectrometry booklet (fantastic!): http://archive.publiclaboratory.org/download/partsandcrafts-spectrometer-guide.pdf (21mb, print quality)

##In progress##

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