  • Using video tracking software for monitoring kites

    Earlier today (5/15/17) I found a interesting video tracking program called Kinovea ([https://www.kinovea.org/](https://www.kinovea.org/)). It's intended purpose was obviously to track various body movements related to sports. Having read about video tracking of kites for airborne wind energy purposes (as a method to guide the kite) I decided to see how well this freeware program could track a ki...

  • How do different time intervals for timelapse cameras affect their required maintenance?

    What I want to do or know Fair Tech Collective folks are investigating options for configuring cameras to monitor oil refineries. We're curious how choices of temporal interval for timelapse cameras correlate with their maintenance needs, e.g. frequency of battery changes, including in different climates? (These cameras would be in the San Francisco Bay Area.)

  • User Interface on Mac

    I've been having issues toggling between modes using a mac. In the tutorial, it says that I can easily click a photo and an option bar will come up. This has not been the case for me. I've found that I can use keyboard shortcuts to toggle between modes (e.g. between distortion and rotation) but cannot use the option bar as advertised. Any advice?

  • Article on monitoring hydrogen sulfide with a copper pipe

    @sara posted [a while ago](/notes/sara/5-2-2012/materials-copper-pipe-work) referring to a technique proposed by Lionel J. Milberger for using copper pipe to detect hydrogen sulfide. The technique involves sanding a section of copper pipe, exposing it for a specific period of time to potential airborne H2S and inspecting it later for discoloration. @gretchengehrke found the source article and w...

  • Early (2014) plant filter prototype

    #First prototype This was developed in a workshop at App State University in the fall of 2014. The setup adapts an existing pot with holes in it (this patching technique is not advised as it may introduce VOCs into the system) and also uses a flowmeter to assess the flow rate of the system, which is not necessary for daily use.

  • Recording kite anemometer sounding data

    Figuring out how to package and record kite anemometer sounding data has been a experimental process. While I have made many flights that gathered some data, I was less focused on recording and compiling that data and more concerned with troubleshooting and learning how to manage all the various parts of the system. Now that all those prior issues are figured out I wanted to begin making fully re...
