Sorry, I've been distracted for the past few weeks and didn't see
this thread. I'm very interested in the "baking my own cake"
version. I'd like to go as far as to take Greg's source code and
tweak it just to see if I can make other interesting things
happen. So I'm hoping the DIY page includes exactly what all of the
"ingredients" are for the cake.
That's the mission . . . at least as we understand it today.
The latest iteration of hardware has been published at:
http://tinyurl.com/6w9vndk
By re-configuring position of resistors marked Flag-1
on the board, two inputs to the uC can be either voltmeter
inputs at about 22 volts full scale or discrete active
pull-down inputs. The fets can be populated with any
size SO-8 device. The absolute max current rating to
be determined during thermal experiments the proof of
concept boards which are on order.
I have no immediate need for a wig-wag, but this looks like a great
way to get some education at a relatively low cost. I haven't seen
anyone else jump on the "me too" bandwagon, but I wanted show support
for what you guys are doing.
Perhaps that group will grow. I have several ideas
for utilization of the hardware package being explored.
Those will wait until first fruits for the wig-wag
project can be harvested.
Anything you care to add to the mix is encouraged and
welcome.

Paul,
Good to see people getting interested in development for this
project. I will be posting the initial C source code for the
wig-wag version of the module today. This is the version that
I will be using to do the hardware integration test when I get
a board from Bob. It has all of the functionality needed
for the wig-wag module but has only had minimal testing
on a breadboard setup to verify the code. I will be doing
some more testing on the breadboard and then on the
initial board from Bob before I would declare it ready
for prime time. Not expecting any major issues but it is
my first time using the PIC micro so there might be
something I missed in my several passes through the
datasheet document.

Subject: | Initial Software Code for the Open Source Wig-Wag Controller |
Here is the initial version of software for the Open Source Wig-Wag
project. I am sending this out for anyone who is interested to take
a look at the code as it stands today and provide feedback. This
initial version is what I will be using to do testing when I get a
controller board from Bob. I have done some initial testing on
a breadboard and it seems to function as expected but I have
not tested all of the details as yet. Feel free to provide any
comments, suggestions, questions, etc. My goal is to have
this as the initial starting point for an open source development
and I expect improvements to come from anyone who
wants to take the time to get involved. Please point out
areas where it can be improved...
I am putting together a description of the development tools
that I used as a reference for anyone else who might want
to get involved in software development for the project.

Subject: | Configuration for reset options on the PIC12F683 for |
Wig-Wag
Bob,
I had a question on which of the reset options should be set up
for the PIC12F683 on the wig-wag project besides the Power
On Reset. Looking at the PIC12F683 document it wasn't obvious
to me which options to enable...
Should the Brown Out Reset and the Power On Timer
functions be enabled for the chip?
Also, did you want the external reset line (MCLR) to be enabled?
I will set up the Configuration Bits as needed...

Subject: | Another Open Source controller idea |
I've been following the Open Source controller thread with some interest.
I enjoy seeing the collaborative aspects of the Internet and Open Source
finally expressed in Experimental-Amateur Built Aircraft.
Recently I became aware of another opportunity for a commercial or
open product. I share it here.
Vertical Power until recently made two basic products: the VP-X and
the VP-200. The VP-X, still manufactured and sold, provides full ECB
protection and some extra functions:
* ECB and electrical display on separate EFIS
* Wig-wag automatic operation (and warmup for HID lights)
* Flap and trim motor control (runaway control, variable speed and
cutoff on airspeed, etc)
* More convenient wiring in that there is no separate wiring to
circuit breakers, and wiring to panel switches is low-current,
high-gage wires. This latter provides opportunities, see below.
It is a fair value for the price ($1300-$1800).
VP also used to make the VP-200 until March 2012. It did all the VP-X
does, plus much more.
Specifically, it offered more than 10 Flight Modes, a dedicated
Display Unit (for electrical and engine status), and Soft Keys in a
Switch Panel. The many flight modes could be customized to turn
different devices on and off automatically during different phases of
flight: pre-start, start, taxi, run-up, take-off, climb, cruise, etc.
With the -200 no longer sold, that leaves the only product with those
features the -400, and a huge price gap between the -X and the -400:
$1800 vs. $8000.
Thus there is a need for an intermediate product between the -X and
the -400: one that excludes the Runway Seeker technology of the -400,
but includes as much of the -200 convenience as practicable.
I'll call this hypothetical intermediate product the VP-X Plus. This
is where the wiring of the -X comes into play: It is not necessary to
create a completely separate product. The non-automated parts of the
-X, that is, the usual panel switches, are controlled by low-power
wiring to physical switches. Those physical switches could be replaced
by an auxiliary hardware device with a small LCD screen and 4 to 6
virtual switches. The LCD screen would provide a dynamic menu and
labels to the virtual switches. If the LCD screen were a touchscreen
it would also serve as the virtual switches, otherwise, physical
switches in a single unit, similar to the -200's Switch Panel, would
be necessary.
This auxiliary unit--the Plus--could also have some intelligence,
enough to detect different flight regimes and operate the various
circuits in a user-programmed pattern (again, like the -200). The VP-X
is getting some flight data from its EFIS connection. If this
information within the -X can be accessed it would be quite a help in
giving the Plus the data it needs to offer flight modes.
The nice thing about offering an auxiliary unit is that it could be
fairly easily wired into existing VP-X configurations. The auxiliary
Plus unit would be mounted so its screen is in the panel, and
additional wires run from the existing physical switches to the
Plus. As an auxiliary or additional unit it would not replace any
existing product.
If the auxiliary unit's design and software were open, then its manufacture,
maintenance, and continued improvements could be done by the OBAM
(EAB) community for much cheaper than a commercial product. It would
offer a significant value-added to the existing commercial VP-X product.
