TLS scanning

Today Jonathan and I performed terrestrial LIDAR scanning of Plots 29 and 37. I learned how to operate the TLS today. I performed the entire scan of plot 37 and 29 from point 526 on my own.

3DR Radio Trumps xBees for Telemetry

After what seems like an endless set of headaches over the xBee telemetyr modules, the end seems to be in sight!  Enter the 3DR Radio modules, a community planned successor to the xBee.  Boasting superior performance and a lower cost than the xBee, 3DR Radio seems like the logical choice.

But does the 3DR actually measure up?  Yes it does.  When doing…
