Most of the used keypads went out in the trash yesterday, under a layer of
other parts.  I just saved a few as spares for my buildings and my dad's
buildings.  Had to check with Dad to remind myself what panels he had.

What's next...  I was going to sell some duct detectors and acrylic mirrors
on Ebay, but the average selling price just wasn't worth my time.  I don't
really want to keep them though.  I am getting really jealous of my
available shelf space.  Dumpster it is.  I've still got three NIB Starlink
3G/4G cells with data cables if somebody wants them and doesn't waste my
time.  $150 shipping included.  One is "shelf worn" from being in my service
truck.  I'll just throw them in a USPS FRB.  I threw away all my other spare
cells.  If its a pain they can go in the dumpster too.  I plan for official
inventory to be zero by the end of the year.
