Subject: | 9lb battery/jumpstart kit shipping cost update. |
Hi Group
I received a request for cost of shipping 3 kits:
USPS Large Flat Rate Box fits 3 kits, cost $15.45 anywhere in the
continental US
USPS Medium Flat Rate Box fits 2 kits, cost $11.35
For sure 1 kit will fit in a Medium Flat Rate Box for $11.35, but if
close to New York 11754 it may be worth it to go Parcel Post. I gave
weight and dimensions of the battery, add some bulk and another 2 pounds
for the other stuff, you can look up on USPS site and figure which way
you would want one to ship.
BTW They were all top off charged as of 2 weeks ago (not a trivial job!).
Also I will provide a schematic for hooking up the charge control
circuit, not very difficult, but it has three outputs, one for charging
the battery and two more, one went to the 15 amp cigarette receptacle and
the other to the volt meter.
This is really a great deal, I just don't have the time to put
together into a fully assembled pack that could be sold pretty easy for
30 or 35$. There are 500 kits at the moment, in a few weeks I will
actively look for a new home for them so if you are on the fence, speak
now.
Here's where the rest of the jump start packs went:

Now all you have to do is find a way to make them stay in
the shell when you insert the radio....
If the pins are not staying in the shell when reinserted, it
may be due to the fact that the locking tab is not engaging the shell.
When
you use the tool to remove the pin, you are deforming the locking tab
into
the pin and it won't grab the shell. After pin removal it is essential
to
pry the tab out, gently, only enough so it will lock in place when
reused.

I agree with the use of a public domain approach. Taking a quick look
at the options for text to be included in software code I found this
FAQ from Creative Commons describing the use of the CC0 option
as a recommended approach for putting new works into the
public domain.
http://wiki.creativecommons.org/CC0_FAQ
It would appear that the CC0 approach could be used for all of the
materials associated with this project. Until there is a standard
approach for the project I plan to use the info above for any software
I send out.

Let us take care that we don't make this more
complex than it needs to be. No matter what
process, intent or forum we use to share these
efforts, the ONLY reason to put a fortress around
all or any part of it is if one intends to defend
the fort. Somebody once suggested during an
Electro-Mech engineering coordination meeting that we seek a
patent on some new gizmo we were working on.
The boss said he didn't have time for that. He
opined that having a patent not only took time to
acquire it, it's was not really useful unless you
were committed to defend it too. He preferred to
get there first, market it best and obsolete it
ourselves with the next generation.
Being good at what you do trumps the efforts
of the lazy who would dishonorably exploit the
creativity of others.
While browsing through the various links to processes
and procedures banners under which we might
march, I was reminded of the Great ISO9000
certification task we took on at Beech. Sweat,
blood and tears were shed to produce a wall of
P&P manuals that we were all supposed to be familiar
with and use for guidance on how to do our work.
They cost our company $millions$ but gave us the
'privilege' of putting that little "ISO9000" sticker
on the sign out front.
I looked through a couple of articles that purported
to be helpful to me in my work, closed the book, put
it back on the shelf and never looked at it again. When
it was known that the ISO Inquisitors were going to visit,
I had things to do over in the EMC lab that day.
Actually, it was pretty easy for the engineers. The
Inquisitor would ask, "What are you doing?" One
would answer, "Just what that guy in the corner
office told me to do."
"What policies and procedures are you bound by?"
"Not a one."
"Say what?"
"Yeah, there is no policy and procedure up on that
wall for organizing the creative thought process."
That usually stopped the inquisition . . . I just
preferred not to deal with them.
I recall some time-study guys sitting on stools
with clip-boards and stop-watches at Cessna back in
'68. They were there for a couple of days and then
left. Hear later that they were unable to tell what
we were doing while staring out the window, "Thinking
about how to solve a problem, or deciding what beer
to pick up on the way home."
The point being that if we do some good things, publish
the works on aerolectric.com and then choose not to defend
or complain about how any of that work is exploited,
then the process by which we choose to publish is moot.
Just as ISO didn't help any of us be better engineers,
the policies and procedures by which we publish our
own versions of 'open source' won't make us better
teachers. Maybe we need to coin our own phrase to
describe the process that doesn't cause folks to run
to the policies and procedures archives to see what
motes and gates have been constructed around what we
do.
There used to be a rather larger "free university"
project in Wichita. Staffed by individuals that ran
the gamut from Phd to skilled practitioner. Their
goals were simple, "I've got something to share. Come
sit for awhile and let's talk."
I think it sufficient to make these projects a simple
extension of what has been done here on this List for
over a decade. Help folks understand and broaden their
horizons.

Subject: | Re: Open Source software license options |
Bob,
I agree completely with what you are saying but I do need to have
some text in the source code I am sending out to indicate that it is
being put into the public domain. I don't know what that text should say
and the most clear guidance I find is that provided in the
Creative Commons CC0 FAQ...
If another version of text is provided for the project I will readily
make the switch...
Anyway, I finished the initial spin on the code and will do some testing on
a breadboard setup before sending it along. Still targeting later this week
to send it out.

Got boards ordered today. Do you have some real PicChips or
are you running a simulation?
I'll plan on sending you a stuffed board with a socket for
the PIC. Also some PicChips. Do you have a handy source for
12VDC power?

Subject: | Poor Man's Battery tester |
I built the poor mans tester Figure 2-4 in AeroElectric Connection. My
only modification was I have three bulbs in parallel to simulate the
load I have on the battery that I estimate at 11amps to run my fuel
pump, ECU, and Ignition. The problem is when I connect the test to the
battery and have all three bulbs on the tester kicks off at 13 volts
with one bulb it kicks off about 10.5 Volts and with 2 bulbs it kicks
off at 12 volts. I have rebuilt the unit with new 10v Zener and I get
the same results. Does anyone have any suggestions what I have done
wrong is do I need to change the resistor size between the load (bulbs)?
Thanks,
Ray

Bob,
I have some PIC12F683 chips and a bench power supply so all
I need is a stuffed board with the chip socket. Do you have the
capability to flash the micro or should I send along some chips
with the code installed?

My programmer is in Wichita. I can wait until
you're satisfied with the program then you can
send me a couple of chips. The mini-board order
yields 6 proof of concept boards. I'll stuff
an couple of extra wig-wag boards.
As soon as we're both happy with the performance,
I'll set up a DIY page that will include the projects
already on the website along with our latest efforts.
Then we can see how many List members want to
bake their own cake . . . or would like to have
one baked for them.

Ray, I thought I had responded to this query. I think
I was in OKC. In any case, there's something fishy about
the shift in shut down voltages you cited. Irrespective
of how many load bulbs are on the tester, it should drop
out at some voltage below 11 volts. When a battery drops
below 10.5 volts, it's 98% used up.
The description of your experiments don't prompt any
thoughts as to what's happening.
If you'll mail your electronics assembly to me I'd
be pleased to troubleshoot it.
