The **Public Lab Timelapse Kit**: fight polluters by catching them on film! _Above image via @glennwalquist -- [read more](/notes/glennwalquist/12-04-2016/monitoring-sargent-sand-mining-operation-in-ludington-michigan#c16131)_ A number of folks are working across the Public Lab network to set up cheap #timelapse cameras. Help out and hold polluters accountable! ## How it works It doesn't completely -- yet! We're testing this approach in a few places around the country, and looking to prove it out more. But the basic idea is to point a timelapse camera at a place where you hope to catch pollution happening, to collect evidence and to pressure them to stop.

The basic kit is based on: > $103 (with 16g SD card) [Crenova Trail Camera](https://www.amazon.com/dp/B016OASTDY/) - 12 megapixel, 8 AA batteries (note that it's actually 5 megapixels, but it stretches images up to 12, unfortunately) Get in touch (jeff@publiclab.org) to organize a local group to assemble, document, and test, and report back how it goes. **** ## Activities [activities:timelapse] **** **Flyer handouts:** timelapse-kit-card.pdf and 4-up version for printing: timelapse-kit-card-4up.pdf **** [](https://publiclab.org/system/images/photos/000/019/546/original/tmp_15415-IMG_20170214_121228_354-1789056372.jpg) (Above, prototype box mock-up) ...
