I was hoping someone could
provide source(s) for the Metrodyne
MPS-3138-015 MEMS absolute
pressure sensor as referenced in Paul
Verhage's column on "A Recording
Weather Station for Near Space and
Beyond" in the June issue. I didn’t see a
parts list in the article or a source for
the MPS-3138. Also, Dr. Google
couldn't seem to find it either.
I purchased my pressure sensors
from Servoflo. Thanks for reading my
A Modest Proposal
In regards to Bryan Bergeron’s
September editorial: Is progress a
conspiracy? My grandmother’s
Atlantic. My grandmother felt guilty if
she didn’t use everything but the
chicken’s cluck. I experienced the
evolution from board level repairs to
swap-and-run service. My grandchildren
consider today’s environmental
indifference equivalent to a war crime.
You ask for a modest proposal for
the current trend in electronics. May I
offer the imposition of punitive deposits
on all electronic products
manufactured, and criminalization of
failing to recycle? Ridiculous? Perhaps.
A few years ago, I had to
discontinue a troubleshooting and
repair course that I was teaching; it was
inconsistent with my student’s long-term career potential, not because it
Breadboarding and restoring may
well be fun and develop the
enthusiasts; they just can’t be cost
justified. I’m writing this response on a
system with a replacement cost of just
a few moments of my not
unreasonable remuneration — a sum
that probably far exceeded my
grandmother’s grandmother’s family’s
lifetime earnings. I do still spend time at
my bench and parts heap.
Great idea, Norman. Sort of like
deposits for recyclable containers. Glad
to hear you're still active.
You Got That Right!
All I can say is 'agree totally' !!!!
with the September Developing
Perspectives editorial. I'm certain many
hackers and electronic enthusiasts
agree, as well. I save some circuit
boards from industrial and consumer
products for the purpose of part
scavenging. However, SMT boards will
go straight to recycle!
