| Subject: | will LR3C work with the Z-13/8? |
I'm tallying up another order to B&C as I build the bones of Z-13/8 and cam
e up with this question: -Will the B&C LR3C controller (which functions a
s a all-in-one regulator, over-voltage protection and low-voltage warning)
work with Z-13/8? -I ask because the tech sheet says the LR3C only works
with "Type B" alternator systems, which I think means the regulator sits be
tween the bus and the alternator. -Looking at Z-13/8, it appears as if it
is designed for a "Type A" alternator whereby the alternator output (the B
lead) gets sent directly to the bus. -It may be that I'm mixed up and th
ey are referring to need to have the field line run from the bus, thru the
regulator and then to the alternator. -Anyone successfully using the LR3C
controller with Z-13/8? -Comments, corrections and suggestions encourage

Hi Sam,
How about a Wii game console remote? These little remotes have a 3-axis
accelerometer, Bluetooth, and an IR camera all for the cost of about $40/ea.
They are durable and available at any Wal-Mart so replacements easy should they
ever get lost, damaged, etc.
There are several examples of interfacing these guys w/ PC's, also. In fact,
some scientific communities are using them instead of high dollar/special
purpose sensors:
http://www.wired.com/wiredscience/2009/12/wiimote-science/
Some more example usage and some Wii remote specs:
http://johnnylee.net/projects/wii/
More info on the remote can be found here:
http://en.wikipedia.org/wiki/Wii_Remote
What I was thinking was:
1) With the accelerometer, they can be accurately aimed straight up thus
ensuring that the distance between the two points is accurate regardless of the
height of the aircraft.
2) Provide a good IR source pointing up.
3) Place some reflective tape on the bottom of the aircraft in such a manner
that it won't affect the surface.
4) Do this on both ends of the runway, throw in some WiFi (to allow
communications and to synchronize the time) , some WiFi and Bluetooth enabled
laptops (Bluetooth dongles cost $20/ea), some programming (there are C, C# and
python libraries available for free), and I'd think you'd have a fairly
inexpensive setup assuming that equipment could be donated, borrowed, and/or
purchased as used.
Some testing would have to be done if a target could even be detected at 100'
AGL in strong daylight. Given that, everything else is doable.
One could go so far as to build dedicated enclosures using micro-ATX
motherboards with all the included components for very reasonable prices.
If you know of anybody with a Wii remote and a Linux based PC, have them look
into the "CWiid" package. It comes with a 'wmgui' demo program so that you, or
anybody else, can get a feel for how things work.

LR3 series regulators are designed to work with
any, wound field, externally regulated alternator
wherein one field brush is permanently connected
to ground (type B). See:
http://aeroelectric.com/Pictures/Schematics/External_Regulator.jpg
Any B&C alternator other than permanent magnet
devices are type B. Virtually all alternators
on type certificated aircraft are type B.
Type A connection is found on INTERNALLY regulated
alternators and feature one field brush connected
to the alternator output or B-terminal are
conventionally called type A. See:
http://aeroelectric.com/Pictures/Schematics/Internal_Regulator.jpg
This is the most popular convention for the vast
majority of automotive alternators.
