Here's a Friday evening question: There seems to be some good work
done by the various ArduPilot projects in both hardware & coding.
Could we not benefit from their work a little, even if as reference
points? Could some of the code be used for A2.5 throttle control?

Fair observation. The LN mail list has been more quiet than I'd prefer :)

from Tridge's talk at LCA.
The latest version of their hardware/software seems to be the
ArduPilotMega v2.0 (the purple one) which is very compact and very
slick.
http://www.diydrones.com/profiles/blogs/apm-2-0-release
It basically just consists of a microcontroller, some storage on the
DataFlash card, a GPS, and 9-degrees-of-freedom worth of IMU sensors -
a 3-axis accelerometer, a 3-axis magnetometer (compass) and a 3-axis
gyro.
It might be of interest to ASRI for Zuni instrumentation, but I'm not
sure how well it ticks all the boxes on all of their requirements.
Maybe it would work. It's one more candidate option. It doesn't seem
to have any provision on board for an RF telemetry downlink, and it
would also need a high-range accelerometer somehow added it to it.
Cheers,
Luke

From conversations ASRI have had in the past, they certainly need a
payload bus, and while the ArduPilotMega v2.0 is excellent kit for
reference and learning from, or expanding, it's not really the spec
they had in mind for Zuni, as you intimate.
The MobSendDat v2 is likely what the Zuni's will need.
I was interested in diving into the ArduPilotMega code, and seeing
what gems of goodness they have already fashioned, that we might
re-purpose, including for the A2.5 motor control board.
Ultimately it would be good to get our hands on a ArduPilotMega and
have a play, along with a Rasberry Pi as a possible test-bed for the
Radar altimeter &/or the JPEG2000 work Lee was working on.

JPEG2000 video/image stuff which requires more computational power.

some time now, although for some different projects than the WLS GLXP
effort. Would be glad to collaborate on these Open platforms and the
Lunar Numbat part of the effort in conjunction with WLS Lander
avionics and other aspects of the GLXP mission like internal/external
telecommunications links based upon CAN and IEEE 802 standards that
Carmen (cc'ed) and I are looking at ...

You may be happy to know that a bunch of us are based in Brisbane too,
including myself & John Scott.

There is much in need of doing, and if you're interested in helping
and have skills you wish to apply, I'm confident we can find
worth-while work for you to do.
We're planning a Brisbane meeting in the not too distant future.

Your collaboration on the open work we're doing sounds great!
Have you also looked at the recent work Luke has done on the proposed
Zuni avionics package? Thoughts, comments?
Cheers,
Marco

That sounds pretty cool - but that's the first I've heard of that!

I suspect that David was referring to the TEDx Canberra talk I gave,
which then got a run with ABC Big Ideas. I'm sure it got a previous
mention.
If anyone is interested, you'll find it here:

that is currently on gitHub:
- Add decoupling capacitor to the MCP3208's reference voltage.
- Connect the 5V rail coming in from the FTDI cable header to the 5V
rail, so almost all the components can be tested on the bench running
off power via the FTDI.
Cheers,
Luke
