On this page the German Public Lab Enthusiasts organize themselves. Here you can find like-minded people and suggest ideas for joint projects, events, etc. ## People who are involved - @niklasjordan – Organizer (Northern Germany) - @alessandra (Stuttgart) ## What are we working on now: #### Event series: Basics of environmental citizen sciences in Schwerin (in planning) - Organizer: @niklasjordan - include developing a fine dust sensor with Arduino - Partnerships (in planning): [BUND](https://www.bund-mecklenburg-vorpommern.de/) (environmental organization) & [Hacklabor](https://hacklabor.de/) (local FabLab) ## Project ideas You have ideas for joint projects? Then write something here. - collecting microplastic with a DIY [LADI trawler](https://civiclaboratory.files.wordpress.com/2016/06/ladi_and_the_trawl-sm.pdf) in diffrent lakes, because microplasty is not one of the criteria underpinning local authorities, and it is therefore not monitored in the long term.
