Subject: | Re: Open source product development for OBAM aircraft |
Would that XPI be most effective when in indexed, indexed direct, or indexed
indirect mode? My favorite instruction was NOP... Octal didn't have a chance.
PDP-8's didn't live long and besides, octal could only represent itself half as
well as hex. 2, 3, 4, (drum rap)
Nibbles, now there was some compact power.
Today, one gets arrested for twiddling their bits in public... Does that
register? Ah, the highs and lows of assembly... For one thing, we never knew
whether we were on the leading edge or the trailing edge... Only Nyqist and our
hairdressers know for sure.

Subject: | Using all the wires |
Hi Guys (Bob)
We are going with the Ztron Labs 'LED Nav/Strobe' lights, the wireing call
out is 2 wire 18AWG sheathed wire for the power feed and return, plus a
seperate 22AWG wire for the strobe sync, I have plenty of 3 wire 18AWG, can
I use the spare wire to feed something else eg: the landing lights
Best regards
John (RV9a-wings)

I love Eagle and have used it extensively. Express PCB is better for my purposes
now (my average PCB is under one-square inch). Furthermore Express PCB's learning
curve is almost ZERO. You can be set up and using it in minutes. Please
note: Express PCB's schematic program is also linked to the PCB.

All,
Regarding the discussions of what "real programmers" use etc. it was
once explained to me that there are only two kinds of programming
languages and those are ones that "everyone" bitches about and argues
against and those that "nobody" uses.

probably . . . but why not use the third wire for
sync. The fact that it's larger than the recommended
wire will not affect performance . . . and this keeps
the strobe wiring nice and tidy.
Can you scan and share the recommended wiring diagram
for your Ztron system? Or is the instllation manual
available on the 'net?

I'm ready to lift the lid on my contribution
to date. The data package is available at:
http://tinyurl.com/7885bd6
Anyone who enjoys . . . and is capable of sifting
the drawings through the sieve of logical
agreement between the data points is welcome
to do so. Critical review welcomed.
I've included a couple of LEDs on the board
that will emulate the fixtures in the airplane.
This will allow any software developers to
hook a switch and 12v power supply to the board
and exercise the fruits of their efforts
on the bench.
I'll take another pass at the 'sieve' tomorrow
and maybe get some boards on order. I have all
the parts.

Indeed:

I propose using a 2 pole switch, OFF - ON(nav only) - ON(nav+strobes)

Subject: | Red Dot SWR Meter |
Bob,
Thanks much for procuring and testing the Red Dot SWR meter. I will put it
to use testing my installed antennas mounted inside my wooden aircraft. No
doubt, there will be questions how best to do these tests, and what are
acceptable parameters.
Have you published the results of your testing of this meter with your
reference?

I will answer and comment to all the previous inquiries.
S. Ramirez: Eagle has schematic capture that, in my opinion, is very good. I
have not used one of the PADS suites in many years so I cannot really comment
on how it compares. Eagle does have
schematic capture that is linked to the board layout. It has an auto-router that
seems to be pretty good if you want to use it. I don't use it myself. You
can download a free copy and try it out
for yourself. It is pretty easy to learn.
Bob N.: I too started with the same stuff you mention. Doing layouts on a drafting
board at 5:1 and flipping translucent sheets to make multilayer boards -
the "good old days". I don't use the
auto-router in Eagle myself, although it is there if one wants it. I would really
recommend you download a copy of the Eagle freeware and check it out. It
is really easy to use and definitely helps
with the final checkouts to make sure you didn't miss anything and that you haven't
done anything stupid. I do the boards I design just like you describe, except
I enter the schematic first and then
switch to the board where all the parts are waiting for me to place wherever I
want them. Then auto-route if you want or manually rout if you prefer (I prefer).
Don't know if it will work, but I
have attached a copy of one of our schematics so you can see what it looks like.
If you don't like what it looks it, you can make and add your own symbols for
anything to the library and use them
instead.
Eric: Express PCB is also very good. The only disadvantage is that it is linked
to the particular board supplier - which is fine as long as that is who you
want to deal with. With Eagle you can use
the Gerber files it generates with any board supplier.
