--> AeroElectric-List message posted by: "James Foerster" <jmfpublic@comcast.net>
Friends,
I have wanted a bright light for landing mounted in the wing of my Jabiru
J400. HID lights employ a High Intensity Discharge through a small quartz
capsule. They put out lots of light per watt, last about 3000 hours, and
have no filament to break from vibration. At first I looked at the HID
projectors, and finally bought one used on eBay. The projectors are mainly
employed for low beams in cars because a shaped piece of sheet metal can be
"focused" and used to create a very sharp cutoff of the light pattern. I
took out this metal beam shaper, easily done, but the pattern was quite wide
and not really a round beam at all due to the designed shape of the
reflector. Furthermore, the whole affair was about 4 to 5 inches in
diameter, and would require a fairing on the wing.
Hella makes a very small 'driving light' called the Micro DE Xenon. see
http://www.hella.com/produktion/HellaPortal/WebSite/Internet_usa/ProductsServices/Performance_Lighting/Xenon/Micro_DE_Xenon/Micro_DE_Xenon.jsp
The part number of 74522, and if you decide to get this, check Google and
Froogle for best price. I paid about $640 for a pair of these-they are not
to be found on eBay. At less than 3 inches in diameter, and only 35 watts,
they should fit your wing. If you mount one on the cowling, the vibration
should not affect the HID capsule, either. You only need one, so you could
split the cost with another builder. Each light plus ballast weighs 1.5
pounds, including the power cable from ballast to lamp. I ran the unit on a
bench supply, from 9 to 15 volts. As the voltage drops, the current
increases, and the light stays the same. This is one bright light.
For a picture of the beam pattern, see
http://www.rallylights.com/hella/Micro_DE.asp and click on the small picture
of the illuminated road. There are two pictures, the one on the left shows
a fog projector pattern, and the one on the right shows the driving light
pattern with the HID source. Note that the fog lamp is the same housing
shape using a halogen filament bulb, the driving lamp has the HID, and the
price reflects these differences.
Roy Lopresti sells a "BoomBeam" (tm) for about $1000 for one. The Hella is
a cheaper was to get something smaller with a similar HID source.
I wasted some time and money checking out the used projectors on eBay. If
you are willing to build a fairing for the wing, or put the unit in the
cowl, the HID projectors could be used. They do have a very wide beam
pattern Otherwise, save some time and aggravation and look at the Micro DE
unit from Hella.
Jim Foerster J400, wiring.

Not so much. I haven't been able to sell mine. Going price for a good
KR-86 seems to be about $300 these days.

This is why I had two ADFs in my Comanche. The advent of general
availability of GPS caused me to remove the KR-86 and just keep the
KR-87.

Well, I've never found any of those critters either, but here is what might
be an interesting effect: I had KX-155's in a 28-volt Cessna and the radios
would occasionally lose their memory (all or some frequencies would get
lost) when the landing gear motor turned on. I Hooked up a high-frequency
scope to numerous places and ground tested it. At the avionics bus the
voltage would drop from 25 (engine not running) to something like 12 when
the motor started. The drop was virtually instantaneous as closely as the
scope would read it and certainly less than 1 microsecond. The drop would
only last a couple of milliseconds and the voltage would come back to maybe
22 with the motor running. King checked the radios and pronounced them
okay - well, they did put in an "upgrade" that was supposed to prevent
exactly that problem, but they never admitted there actually was a problem.
The problem remained. Question was, why would the radios drop out under
this condition when you could turn them off and on and never get the
problem. My hypothesis was that when you disconnect power from a device the
internal voltage drops gradually, allowing the computer to shut down
gracefully. Many micros have a shutdown mode that saves certain things to
non-volatile memory as the voltage drops. When you essentially short the
power to ground, like through a starter motor, the voltage drops too fast
for the micro to shut down correctly. This inherently makes no sense as the
micro is powered by an internal voltage regulator that isolates it from the
battery, but...? I believe these radios had no reverse polarity protection
and I assume that means they didn't have a diode on the power line to
prevent reverse current flow. I wonder if the sudden drop in voltage caused
the input filter caps to conduct, possibly in concert with an input
inductor, to create a negative voltage transient inside the radio even if
there wasn't one outside. I never solved the mystery, but we changed to
Garmin radios.

Flamesuit? What's that? Why would anyone on the AeroElectric-
List need one? We're looking for the simple-ideas that fit together
into low parts count, easy to operate, inexpensive to own electrical
systems that perform better than anything certified.
There are inventions based on simple-ideas and inventions that
suffer from tradition non-science and rumor. Neat thing about
simple-ideas is that they are always very tiny . . . easy to
sift out from the lumpy things that are fabrications of poor
science and ill-considered design.
Our mission here is to equip everyone with the fine sieve
that separates the lumps from the good stuff. We should expect,
nay hope, that this topic (among many others) continues to
bubble up. Every time it does, it's an opportunity to outfit
a brother builder with another useful tool. When it stops
bubbling up, it means that everyone has all the tools they
need (never happen) or that we've made people feel like they're
being chased away.
There are four reasons for folks to communicate with each
other. To be informative, to entertain, to persuade, and
to cause discomfort. Can't speak for the rest of you but
I welcome the informers and entertainers. Let's hope that
the atmosphere we maintain here is inviting to those who
wish to share informative, sometimes humorous speech.
The rest will eventually take notice that their favorite
style of communication is better suited to television
commercials or rap lyrics.

What is the function of the "avionics master"? What we're discussing
is a design feature of certain pieces of equipment that causes them
to reset when presented with a bus voltage below some value for a few
milliseconds. Adding a switch in series with these devices only serves
to delay operability of these devices by waiting to turn them on
until after the engine is started . . . the fact that the gizmo resets
during a brownout is not indicative of an overstress to the product
that demands pilot intervention for protection.

Yup, if there are gizmos that won't stay awake during a starter motor
brownout and in your role as a system designer you have determined
that automatic resetting is an unacceptable behavior, then you'll
need to offer these devices a "protected" supply.
Starter inrush brownout happens . . . you can't stop it. See:
http://www.aeroelectric.com/Pictures/starter_brownout.jpg
Here's a trace taken from my wife's Saturn with a fairly stiff
battery. It has a PM starter with a healthy lock-rotor current.
Hence, hitting the starter causes battery voltage to sag
as low as 7.5 volts for a few milliseconds. None the less, the
EFI system in this car is DESIGNED to live with life's little
nagging realities and the car starts right up and the alternator
comes alive in just over 1 second after hitting the starter.
The question that needs to be asked and answered is: "Is there
some hazard to the gizmo under consideration by forcing/allowing
it to do an automatic reset when the starter contactor first
closes?" In the (ugh) certified world, we're not permitted to
install systems for which such events present a hazard. Functionality
needs to be evaluated and designed such that any automatic
resets don't matter.
So be wary of broad brush "solutions" based on inadequate
consideration of your systems operating characteristics and
your design goals for behavior. How long does it take for
the system to come back alive after a reset? Is this unacceptable
from an operational perspective or does it just "bug" you?
I can tell you that when after a Beechjet starts up, the
panel is a xmas tree of flashing lights and screens as the
various systems wake up, get out of bed and prepare to go
to work. Lots of things are temporarily out of service
for up to 20 seconds even though their lights and screens
are busy.
You need to separate the considerations in to two piles:
(1) Operational issues that represent hazard to equipment
not designed to live in the real world of airplanes and
(2) operational issues that cause inconvenience. Then
decide which ones require extra batteries, avionics
masters, etc., etc. as work-arounds.
You may well discover/decide that this is just how the
system functions and nothing out of the ordinary is either
necessary or desirable.

I've been seeing these adds on TV for a battery
operated soldering iron. It's supposed to heat up
and cool down very quickly and only when you stick
solder against the tip.
Before I send them my $20+SH, I thought I'd ask if
anyone has tried one of these?

While I'd be suspicious at that price, it isn't a certainty that
inexpensive = useless. I own some high dollar soldering stations, but I
carry a sub-$5 iron in my tool box & can do adequate soldering with it.
(I've had LOTS of practice.)
Technology is the only thing that gets cheaper as time goes by. I paid
over $100 for my good solder stations 25 years ago. Equivalent models
from the same mfgr cost around $50 today.
Here's a thought: Using the replaceable pins for sub-D connectors, I can
build a connector with my $5 iron that's just as reliable as one built
with the multi-hundred dollar crimpers, and spend only slightly more
time doing it. All it takes is practice to do this, just like it took
practice to learn riveting.
Ya pays your money & ya takes your choice...

I really wanted this thing to work. It runs on AA's instead of the
expensive rechargeable batteries that my (relatively expensive) portable
soldering iron uses. I've tried using it and found it to be worthless.
There may be an application that it will work for, but that's not good
enough. It needs to be able to solder all of my jobs, not the occasional
one.
The way it works is to short circuit the 4 AA batteries it uses between the
two part tip. The wire or whatever you are trying to solder completes the
short circuit. In my experience it does not work. The degree of precision
that the tip must be placed and held for it to work is beyond ridiculous.
Save your money and buy an Isotip rechargeable if you need a portable iron.
I use the large tip for most of what I do. It's not large compared to an
electric soldering iron. The tiny tip is great for really small wires but
doesn't hold the heat well enough for larger wires.

| Subject: | Rumination: Automatic standby fuel pump? |
--> AeroElectric-List message posted by: Richard Riley <richard@riley.net>
I've now seen 2 small airplanes destroyed by engine driven fuel pumps that
failed - one on take off, one on landing - and pilots who didn't get the
backup electrical fuel pump on quickly enough for a re-start. Yes, they
probably should have just had them on for takeoff and landing, but that
wasn't the case.
I'm thinking of wiring my fuel pump with a SPDT switch. Up would be ON,
down would be AUTO. There'd be a pair of pressure switches - one sensing
oil pressure, the other fuel pressure. If the swich was in auto, there was
oil pressure, and fuel pressure fell below a pre-set limit, the pump would
turn on.
Now, one problem is that the electric pump makes higher pressure than the
mechanical pump, so I'd have to do some kind of electronic or mechanical
latch, to keep the pump on, rather than having it cycle on and off every
couple of seconds.
Any thoughts?

Thanks for saving me $20, David (actually, it would probably be $35 once
they add the "S&H").
Sometimes you see these sorts of tools and they are worth their weight
in gold. Most of the time they are worse than trash, as they are a
distraction and you spend hours fiddling with them because (like you
said) you really want them to work.
I like the idea of the battery power, as butane is somewhat dangerous to
bang around in a bag, but I'll wait till they get the working version at
Sears.

For RS-232, it shouldn't make any difference.
And when are you going to use a keypad in flight? That strikes me as
pretty tough to use while flying your airplane.

This is a problem I would solve mechanically rather than electrically.
I would have an overpressure relief valve that just shunts the fuel
back to the inlet of the most-upstream pump. That would keep the
pressure at the inlet to your fuel metering system (carb, injection
system, whatever) from rising too high. Now you just turn on the boost
pump before take-off and don't worry about it.

We have a Bonanza with a peculiar electrical load issue.
With everything electric ON - - pitot heat, nav, rotating beacon, radios, AND
one (and only one) of two landing lights - - the 14V system charges just fine
on the ground at about 1500 RPM, maintaining a full 14.x volts.
Do the same thing with everything OFF, except the landing light - - and NOW - -
add the second landing light, and the entire system discharges hard at the same
1500 RPM, down to a buss voltage of about 12.5.
It doesn't make any difference which of the two landing lights you use, in either
order, for the test.
I am having a hard time understanding that one landing light is a much bigger load
than the rest of the entire aircraft systems (including the pitot).
It appears that there is some kind of short developing when both landing light
switches are ON, rather than either one ON, by itself.
Any thoughts or ideas?

Why not just leave the pump on all the time.
Have a spare ($30.00 ??) handy and replace it every 1 or 2 or 5 years.
Simple and not that costly.
Just a thought. Since you asked.

IMO this is not quite as simple as it seems. I think you'd want the pump
to latch on so that it stays on until manually turned off which probably
means using a relay (or an SCR). Since you'd want to know that it had
come on, that probably means an indicator light. Now you need a method
of shutting it off and checking to see if the engine pump has really
failed which means something like a 3 position Auto-Off-On switch. I
prefer the bottom position of such a switch to be Off which adds another
small complication. You also need a pressure switch that will for sure
tolerate gasolene or use a comparator to pick a signal off your fuel
pressure gauge if it is an electric gauge. If going that route, you
could use the comparator to latch the pump on.
I decided to run two pumps while in the traffic pattern ;)

Boy, that would be a fun gremlin to chase out. Does the airplane have an
alternator loadmeter? It would be interesting to watch measured alternator
output current and field voltage during the various conditions you've cited.
You need to know if it's the alternator maxing out for some reason (field
voltage stops rising at just a volt or so below bus volgate) or if the
regulator is actually shutting the alternator down (field voltage at some
value well below bus voltage when the antagonistic load is applied).
Do you have a test shunt and external instrument you can install in the
alternator's b-leads?

Aha! I've seen that ad on TV too and was wondering about the technology
involved. Your description has saved me from having to buy one myself.
The technology you're describing has been around in some form or another
for over a century and is called "resistance soldering". I've never found
it attractive for my own work but I've known a number of technicians
who swear by it. I've used it to play with but find temperature controlled
irons much simpler to use. Some examples of the tools can be seen at:

For my money, the premier soldering tools are made by METCAL. Go
to Ebay and searche on 'metcal'. You'll get about 100 hits
on solder stations, handles, tips and complete systems. I buy
the older PS2E power supplies separate. Folks don't seem to covet
the antique stations as much and when they don't come with handles
and tips, the prices don't get out of whack. I've picked up
several power supplies for under $150 and I usually just buy
new handles and tips from the electronics suppliers. I'll have
a really good solder station for under $250. But set your price
limit and bit those ebay systems. You'll probably get one
eventually and you can't find a finer soldering tool for the
money anywhere else.

Here's one that will probably go for under $150

Here's a real clean one that I'd go up to $250 on.

Is the VR sensing the buss someplace different than the over-voltage
protection circuit/relay? If you have some resistance between the
output of the alternator and the VR sense with the VR sense near your
loads, the output of the alternator could go high and trip the
over-voltage protection circuit.
This may just be one of those times where you have to trace down
voltage drops in the system.

There is a time to laud one's country and a time to protest. A good
citizen is prepared to do either as the need arises.

Thanks, Brian. What I referred to as a keypad is actually a remote location
for the buttons and knobs on the right side of the EFIS screen. I put them
on the left right above the throttle so I can completely control the EFIS
with my left hand and won't have to let go of the stick in my right hand. I
really like the way the combination of four buttons and two concentric
rotating knobs control everything. The keyBOARD won't be on board unless
it's a cross country, and then it will be in the baggage compartment.

For RS-232, it shouldn't make any difference.
And when are you going to use a keypad in flight? That strikes me as
pretty tough to use while flying your airplane.
