The Infragram project brings together a range of different efforts to make Do-It-Yourself plant health comparisons possible with infrared photography. Vineyards, large farms, and NASA all use near-infrared photography for assessment, usually by mounting expensive sensors on airplanes and satellites. Infrared analysis is used for a variety of things, but most focus on assessing plant health, such as:
- to assess crops and #agricultural practices
- better #soil management (reducing #fertilizer, soil treatments)
- in #wetlands analysis

The Public Lab spectrometry project is an open source community effort to develop low-cost spectrometers for a range of purposes. Our most recent projects are the Lego Spectrometer Kit and the Papercraft Spectrometer Kit.
The Basic Microscope Kit is an introductory Do-It-Yourself microscope made from affordable and easy to find parts. Our goal is to measure #silica particles in the air, #microplastics, and other things using a simple-to-assemble kit.

The Hydrogen Sulfide Copper Prototyping Kit is a new project looking at whether burnishing copper can be used as a means to measure the presence of toxic hydrogen sulfide gas. This is an early prototype which needs a lot of work on initial kit design and testing:
