matt's comments are cogent and should be heeded. I wish Obama care had
done that WRT the electronic medical record. While pacemaker
manufacturers followed IEEE standardization; most medical companies
don't. The standardiization of avionics data streams should be adhered
to. "Proprietary" data will ensure a companies "stuff" won't be used IMHO.

Sure. This has been well understood for decades . . .
at least in my circle of colleagues. DO160, MIL-STD-704,
and a host of other cooperative ventures by capable
and cognizant practitioners of the arts
made it possible for makers of Murphy's Flying Flivers
to buy components from Black Boxes, Inc, and Generators-R-
Us with a high order confidence for achieving seamless
integration. All this in spite of the fact that
airplane guys, electro-mechanical guys and electron-
herders had no direct contact or collaboration with
each other.
The risks to elegant solutions rise when (1) new
guys on the block fail to see the advantages of
such standards and/or (2) the producers of standards
become less collegial, less cognizant of the art
and more dictatorial in their production of requirements.
It matters little whether you're studying the
operation of governments, schools, companies,
or home owner's associations. A cooperative
venture to insure free-market exchange of value
amongst capable competitors suppling a needful
customer base waving credit cards is the time
honored, well proven recipe for success.
Yes, there ARE examples of ground-breaking
ventures that pulled off a successful enterprise
that included some degree of creative destruction.
But creating a new communications protocol in
a community of well established and widely
practiced protocols is like walking into
a classroom offering to deliver the world's most
spellbinding lecture . . . in Swahili or Gaelic.
Fortunately, Dynon is a relatively small and
I hope agile organization. If still lead by
capable participants in the world of spontaneous
order, they will see the light and make useful
course corrections. In the mean time, the best
thing we can do to help is offer constructive
critical review and suggestions. It wouldn't
hurt to include a small feint as well . . .
make little motions that suggest the credit
card is going back into your pocket.

Skyview 5.1 EMS Data
I assisted both Garmin and Dynon in the writing of a common interface
specification (called FIX: Flight Information eXchange) for Attitude/Airdata
and EMS data. I invested a lot of my time and both companies agreed to the
common specification... including modifying their own protocol to allow for
commonality.
When Dynon production released their version, they added one field in the
air data, making it incompatible with the Garmin version. Now, apparently
they have changed the EMS data as well.
One small victory is that each company uses its own delimiter and version
number so it is possible in software to determine the format.
What we need is an industry group that produces interoperability
specifications. Unfortunately, our industry is too small to support such an
effort, so it's up to groups like MakerPlane to produce open standards for
EFIS data and such. One thing for sure, I will never donate my time to this
effort again. Shame on Dynon and shame on me.

Subject: AeroElectric-List: Re: (Case 117320) VP-200 Compatibility with
Dynon Skyview 5.1 EMS Data
(I sent the message below to Dynon this afternoon. FYI -Matt)
Dear Dynon Support,
I was forwarded the text immediately below regarding the new Skyview Version
5.1 issue and EMS data stream compatibility with Vertical Power VP-200
I think that Dynon is kind of missing the point here. Dynon has, for all
intents and purposes, developed a "standard" for this EMS data format.
Whether arbitrary 3rd parties use it and/or communicate that use to Dynon is
also beside the point. Dynon has committed to a certain format and as such
cannot change it without incurring some serious, potentially negative and/or
life threatening ramifications in the field. The designers of TCP/IP didn't
just randomly decide to change the order and meaning byte values in the
standard. A standard is a standard. When its done and released, *its
done*. Version 1.0 cannot be updated.
Adding a "version string" to the data stream doesn't work either as the
devices listening to version 1.0 don't know the version string is there and
are equally as broken.
The only option is to version each new format and allow the user to select
between the various version. Or, depending on the flexibility of the
protocol, ADD new data strings to the format. But the original data strings
*cannot* be changed. For example, in NMEA0183, $GPGGAxxx, $GPRMCxxx etc.
allow for a progression of new formats to be added. But the format of
$GPGGAxxx always has to remain the same.
I work at a Government research laboratory in Livermore where I engineer and
write embedded firmware for remote security terminals that are used
throughout the Department of Energy sites. Part of that responsibility is
to design, implement, and utilize serial protocols for communicating between
various devices over both RS485 and Ethernet. If I were to make a change to
our protocol like Dynon has done in the upgrade between 5.0 and 5.1, I would
be fired. Plain and simple. Even IF everyone that is using the protocol
happens to be notified of the change, there is still the issue of
incrementally upgrading all of the end devices.
I guess my point here is that Dynon needs to take their various
"proprietary" serial protocols a whole lot more seriously. I believe this
is now at least the *third* time that a protocol change has adversely
impacted the user community. That is *not* acceptable. I would have
probably been fired after the first indiscretion, if not strongly
reprimanded. The second and third times would just not have happened.
For protocol versioning control, Dynon needs to either add additional named
strings to their protocol or they need to simply start versioning each
change AND including support for all versions in their products. For
example, the user should be able to select between EMS Version 1 or EMS
Version 2 or EMS Version 3 from the configuration menu. The format of EMS
Version 1 or any previous versions can never change; period.
And finally, given Dynon's lackadaisical attitude toward their protocol
specifications, I find it almost impossible to believe that a simple
downgrade from Version 5.1 to 5.0 is, by default, disallowed? Why aren't
the same Draconian version control practices imposed on the customers,
applied to their software developers as well?

Skyview 5.1 EMS Data
This is the first I've heard of this problem. As the buyer of the last
VP-200 unit, still uninstalled, and planning on using Dynon's Skyview
system, this is not good news. What's Vertical Power's position on
this? Are they going to do anything to keep the firmware of the VP-200
updated for a few more years?

That terminal is used in a variety of products
including holders ATC plastic fuses where the wires
come in through the mounting surface to the back side
of the holder or, in this case, up under the fuse
holder from the front side of the mounting surface.

Greetings,
I was inspecting anew electronic device that wasn't working and found a
solder bridge between 2 of the pins on an SMT chip.
I'm looking for an easy way to remove it. My plan is to use a hot
needle to touch it and maybe I can sweep or blow it away. I'm open to
suggestions, keeping in mind I have no equipment for working on SMT
components.
do not archive
Thanks in advance for any suggestions.

These seem to be pretty uncommon, since Digi-key, Mouser etc. don't seem to carry

Jeff,
I used a rear feed fuse block that used these terminals. There is also a
removal tool for them that was useful. Here is link to a website that has
the terminals, blocks, and exctraction tool.
If the link doesn't work, the company is MIH Industries.
Hope this helps.

One of the "Rich-man's problems" involved in designing and selling LEDs is that
the technology is moving so fast, just as one cool device is ready to sell, it
is obsolete.
Cree has recently announced a 200 lumen/watt LED and has published a reference
design for an MR-16 design that is free to use and will almost instantly result
in marketed products.
Not to be outdone, Phillips-Luxeon has released their Luxeon-M which has an enormous
output (but lower efficiency than the Cree device) and furthermore works
on 12VDC. It apparently will produce >1000 lumens at 12V 1000 milliamps. This
is especially advantageous because it needs no (or a minimal) power supply for
12-14.5V systems.
As always YMMV.

Wow. That helped a lot. Turns out this terminal is used in many GM vehicles,
so lots of auto parts places have it.
In case anyone else is looking for it, search for PackCon III. They are available
for different size wires.
It seems the automotive ones are not plated, but rumor has it that the John Deere
57M7508 is.

Regular soldering iron and good quality solder braid/wick. Optionally flux.
In a pinch you can do it with just the iron - melt a ball of solder on the
end of the iron and drag it across the pins at the right speed, the surface
tension will pull out the bridge. Flux helps.

Just drag the hot tip between the bridged terminals, just slow enough to mel
t the solder.

Jeff,
I used a rear feed fuse block that used these terminals. There is also a
removal tool for them that was useful. Here is link to a website that has
the terminals, blocks, and exctraction tool.
If the link doesn't work, the company is MIH Industries.
Hope this helps.

So many connectors and no good way to sort through them all.
Does anyone know what terminal this is ?

Standard reflow soldering profiles peak around 230 deg C, and that should be
plenty to fix your bridge. Just clean and tin your tip, then drag it acros
s the bridged pins, pulling the bridge away. If there's a lot of excess sol
der there, you may need solder wick, but be careful how long you dwell with t
he iron against the component. As a previous post suggested, a little flux o
n the wick will help to draw away the excess solder.
