I’ve finished a playlist on building the LEGACY nitrogen-fixation instrument, although there may be some minor changes if I decide to offer a kit of parts, rather than just the bare board. I plan a series showing the use of the instrument to measure nitrogen-fixation efficiency. And I’m working on an online course tentatively titled “Darwinian agriculture: evolutionary tradeoffs as opportunities” which I hope to release through Coursera. Meanwhile, I’ve uploaded some videos of my past talks to my YouTube Channel.
