The Soybean Cyst Nematode Extractor

After a couple years of tinkering, we finally have a working prototype of the Soybean Cyst Nematode Egg Extraction System, or our SCNExtractor for short. The following video shows the operation cycle of the SCNExtractor. We built this prototype as a two-channel system. The entire cycle consists of approximately four minutes, from sample loading to egg retrieval. Once the eggs are retreived from the sample collection funnels, they are stained and imaged. Computer vision then enables automatic egg counting. 

Document version control

Dropbox doesn't cut it for collaborative work where multiple people want to make changes to a document. And no Track Changes doesn't work either. So we have now set up a distributed version control system called Git.

Here is a really good book for understanding and using Git. Of course, since all our work is 'top secret', we have restricted access to everyone using git. If I have asked you to join a git project, here's what you need to do:
