Info

The datafile that comes out of Loggernet, an ascii comma separated .dat file (LoggerNet "TOA5" format) was parsed and pushed into my RBNB server with a small java program I wrote (DatToRBNB.java). This program can create a new RBNB channelmap using all the data in a TOA5 file or be periodically run on a growing file to append to an existing channelmap. (* currently have a bug w/ append mode periodically dropping old data). DatToRBNB can also be used to pull data from RBNB and print it to stdout (in fact pulling data is also done when pushing using append mode, to gather knowledge about the state of the existing RBNB data before appending).

Note: Don't try to read too much into these plots--data were collected indoors, from hardware that was occasionally moved about, powered off, etc. DatToRBNB.java and the RBNBToKepler2 actor were both being modified as well.

Pictures

A terrible wiring job, when we deploy we should tie-off to the sides in enclosure (and along tripod etc) for strain relief / future sanity. Solar panel mounted upside down, I've since flipped the arm so it can be more easily mounted w/ a good incidence angle on the mast right side up. Depending on grass height, we could alternatively mount it on a leg. Note also the radio sitting on top--this with antenna cable going into lightening arrestor will need to be mounted/set/tied in some way inside the enclosure.

2 reflectometers, 2 line quantum sensors, 1 (qsosun) quantum sensor, rain gage without bucket (will be mounted on a separate post, away from tripod), grounding rod and cable in background. We need to order a mount for the qsosun, and figure how to mount it so it doesn't interfere--do we need a second crossarm?
