the weather station recorded the

Driving to Work
Between two snow days, I placed
the recording weather station on the
dash of my car with a program to
record speed and direction as if the
car was a weather balloon.
Radiosondes are weather stations
carried by weather balloons. The
National Weather Service launches
some 200 of these a day in the US
from airports like the one in Boise.
Rather than record temperature,
pressure, and relative humidity up to
100,000 feet, I’m recording the same
conditions on the ground and at an
altitude of 400 feet using my Blade
Two things I’ve learned so far is
that the MPS-3138 can easily detect
pressure at 400
feet AGL, and that
I need to let the
drone hover for a
minute at altitude
to allow the
sensor to cool to
temperature before returning to
I probably won’t have a chance
to fly the recording weather station
until the Great Plains Super Launch
in Hutchinson, KS this June. That
launch will be a test and preparation
for the solar eclipse on August 21st.
I’m curious to see if any differences
in temperature, pressure, or relative
humidity are apparent during the
eclipse. So, keep your eyes open for
a major report on my eclipse results
that will include a weather station in

I discovered that I created an incorrect
schematic in April's Near Space column.
The corrected schematic is shown here and
is also available at the article link. I want to
apologize to the readers for not catching
this error. I hope no one was pulling out
their hair trying to make the circuit work.
