It would certainly be greener to get companies to minimize shipping charges (that
could be a click-box!). I get a lot of little packages where HS tubing, metal
rods, etc. are packed like gun barrels. It would take a only a few seconds
of thinking to minimize the shipping charges.
I also try to stop big, expensive printed catalogs, when I use the Internet almost
exclusively. What does Digi-key's 2800-page catalog cost?
Somebody is making $$$ off this waste.

switch and trim servos
Andy,
Have you considered the Intelligent Flap Controller
<http://www.tcwtech.com/IFC-1-page.htm> from TCW Tech? Seems like this
will do all of the switching for you.
Also, have you considered the stick grip from Tosten Manufacturing
<http://www.tostenmanufacturing.com/catalog/aircraft-grips/>, perhaps
linked up to a TCW Safety-Trim
<http://www.tcwtech.com/Safety-Trim-Page.htm> box?
Regards, Peter

Living in the hinterlands, I get a LOT of stuff
delivered to my mailbox and front porch. Yeah,
from time to time I get a tiny what'sit in a
big box but in the grand scheme of things I
find that most packaging is appropriate to the
task. Go watch the folks at the shipping tables
of an operation like Digikey. Digikey has UPS
and FEDEX airplanes sitting at the Thief River
Falls International Airport awaiting just THEIR
shipping tasks for the day. To suggest that these
or similarly engaged folks are institutionally
or environmentally irresponsible is something of a stretch.
The reason we shop with those folks is because they're
fast and priced at a level we're willing to pay.
To put some "click box" generated wrench in their
flow of tasks to satisfy what is probably the
wishes of one customer in 1000 is . . . well . . .
It's a free market. If you don't like the way
some supplier is treating you . . . find a
more pleasing supplier . . .

You can go to your profile in Digikey and shut off
the paper catalog mailings. I got a 6-pounder from
Mouser yesterday, got to get that shut off too.
At the same time, the paper catalog is exceedingly
useful to some customers when doing comparison
shopping . . . you and I go to the website and
punch in a number . . . we already knew. But
when it comes to browsing the constellation of
choices, thumbing through the pages is hard to
beat. Catalogs are also a huge teaching tool
for the neophyte purchaser. You have illustrations,
descriptions, specs, prices, jargon . . . all
those mystifying things surrounding electro-whizzies
that have to be learned. And you get it all in
a FREE textbook.
>Somebody is making $$$ off this waste.
Lots of folks are making money keeping a lot of customers
coming back for exemplary service and quality. Pushing
our judgements of "waste" onto their activities can
be a consideration for picking amongst the various
service providers. But to launch a crusade based
upon that judgement is counter-productive and guaranteed
to be ineffectual.

Subject: | Extra switch function ideas? |
When I was figuring out my ground power jack switching, I thought that it would
be nice to have a test function in the switch to protect my electrical system
from inadvertent reverse polarity or excessive voltage.
So, nevermind that Bob's design took all this into account, I got a cool Honeywell
switch that is a 3 position, MOM-MAINTAIN-MAINTAIN. My myopia became apparent
when I was doing my wire book page for this circuit and I saw that the "test"
function (MOM position) did nothing different than just throwing the switch
for GP function. If something was amiss, per Bob's design, the 2a breaker
fries and you investigate.
So my question to the group is , What else might I use the MOM function of the
switch for, other than to connect it to my brain to push ON before I start thinking
about cool ideas.
Thanks,
John
