Rob recently documented his nook installation from his glider here:
http://xcsoar-robd.wikispaces.com/XCSoar+on+Nook+Simple+Touch
He hooked it up to his cai302 via serial and patches in the power from the aircraft battery.
I think this is the most cost effective way for a sunlight readable glide computer to date. The costs are around 100 USD.

barely used for $45 to $75. Can't beat that.
I like the super crisp B&W display.

NOOK seems to be better than anything else at the moment. I hope
there will bee soon something smaller (4.5 inch ?) available. That
would fit better in gliders.
We (Soartronic) hope that the next IOIO board, that is USB OTG
capable, will work with NOOK!

Cool!
Glad to see this. I have had XCsoar running (simulation mode)on a Nook Color using an N2A card, which basically turns the Nook into an Android tablet. The Nook looks much better than my 4700 in sunlight. The intent was to connect to GPS via Bluetooth. Unfortunately, while it will see Bluetooth devices, I have not been able to pair. Maybe one of you really smart people can figure out why....

Perfect, I purchased a Nook Simple Touch, just to explore this possibility. I will be following this closely and will probably work on implementing it in the next few months. If I can get it away from my wife long enough to try it.

This has piqued my interest some and I was wondering whether an old Cambridge 10, 20, or 25 model that outputs serial GPS could be used as the GPS engine for the Nook?
I know it would not have the vario information but would it be as accurate as a standalone Dell Streak say?

sentence that contains GPS altitude, and the most common firmware

handshake sequence which (to my knowledge) has not been revealed to
3rd parties. So, you could see your position on the Nook, but you'd
likely be out of luck on altitude...

My experience is, that CAI and Volkslogger GPS signals are quite a
lot delayed. Might be slow communication speed, or filtering. This
makes it difficult to use moving map for navigation. FLARM works
much better.

I've rooted a Nook and installed XCSoar, per the instructions on Robs Wiki page. I flew last weekend with a serial-to-USB cable ported to my CAI-302. The display is awsome and completely readable in direct sunlight!
My fondest wish is that a version of XCSoar might come available that is grey-scaled, to make it more compatible with the E-Ink display.
Thanks Rob!

What you can do:

- write a feature request ticket in the XCSoar bug tracker:
http://bugs.xcsoar.org/newticket
Write as exactly as possible what you wish XCSoar to do in the
presence of a grey-scale display.
- collect donations to buy an E-Ink device for an active XCSoar
developer
- motivate somebody to join the XCSoar team and to implement your
ideas; this is the most important part, because time is the most
difficult limit we have to deal with, and more brains means more
wishes come true!

There's ongoing development to the Nook's kernel at xda-developers to display screen colors as dithered shades of gray automatically. This solution will allow color applications (e.g. XCSoar) to work without color modification on the Nook's EInk screen.

When eink is used for reading books, a display mode is used that gives the most crisp fonts possible. In this mode each pixel can be one of a number of grey shades (usually 16), but at the cost of a slow refresh rate and the need to occasionally flash the screen black (this clears away pixels that have been left in an indeterminate state of grey and ensures you get a consistent, clear picture).

For XCSoar another display mode is used. This only allows each pixel to be black or white, but gives a fast refresh rate. We then use a dithering method (similar to halftoning in printed newspapers) to generate greys. Old school techniques, but they eliminate most of the perceived disadvantages of eink.

I too am interested in an eInk FGC. Thank you for your efforts and please keep the ball rolling.
eInk specs and OS vary greatly from one device to the next so a few questions if I may.
How is NEMA and FLARM info integrated with an eInk device?
Is it correct to assume this XCSoar effort is specific only to the Nook Touch?

Folks,
I used a Nook with XC Soar at a contest recently for 2 days. I have to say
that it is absolutely the best display I have ever seen outside. When the
sun
hits it, there is no glare or wash out. No strain on the eyes. Just
incredible. As
far as XCSoar I find it tedious and time consuming and find myself with my
head down to much. As far as user friendly, I find XCSoar over
complicated.
Compared to Glider Navigator 2, which is the simplest program I have ever
used. I do have to give credit to Rob Dunning for simplifying a version on
XCSoar, which is much better, but still frustrating, especially when you
need
to change a setting or task quickly.
The Nook display is just amazing, as far as the refresh rate with XCSoar,
it's
plenty fast enough, and found it comparable to my newer PDA.
It is black and white, still great though. Cheap also!

The nook has an USB OTG (On the Go) port. This port has limited USB Host capability. Basically you hook up an usb serial (rs232) converter up to the device which is then connected to a FLARM. That gives you GPS, Barometric (the one inside FLARM) and FLARM data.

For power you split the USB-OTG cable up and hook up the power lines via a 12v-5v converter to the aircraft battery.
This is all nicely documented on robs page.

What setting did you try to change inflight that you found the steps to frustrating?
I don't know if you know this:
Some gestures where added recently to facilitate the task editing quickly: Just draw an inverse L with your finger over the map screen for the task editor. A normal L on the map screen opens the waypoint selector.
Using two fingers on the map will pan it.
For all the info boxes you can press and hold for 2 seconds on the particular box, to access settings such as mc value etc.

It has lots of great and NEW features but no one knows about them
except the "inner circle" of developers and dedicated users.
New users are in the dark as the 170-odd page manual is not up to date
and has many sections that are incomplete.
Would someone please write an XCSoar Feature List with just a line or
two about every possible thing that this
amazing program can do? (Or maybe make a YouTube video. Found one but
it is rather old.)
That way if we just know it is possible, we can find it and explore
it. Otherwise we are,

manual, not much different from Folken's post. See page 33, in a
section called "Interfacing with gestures".
Yes, you are right, we have big trouble keeping it up to date (due to
lack of volunteers), but this time, you're not doing us justice.

Touchscreens are bad enough in a cockpit enviromment, but gestures? You guys are going in the wrong direction, IMO. Stick mounted or remote controls are a much better way to control software displays, followed by momentary touch buttons or areas on the screen.
What we need is a universal stick with a variety of input devices that would interface with all popular gliding apps, removing the need for touchscreens altogether.

66, while I don't agree about joy sticks over touch screens, there are many who do agree. I think it's a personal preference. I do believe that there is an opportunity to improve glide computers. The most important factor is the effort spent on a glide computer's design.
> interface with all popular gliding apps, removing the need for touchscreens altogether.
Unfortunately, it is hard to change the core "user interface" design of a glide computer because change forces pilots who use it to relearn the system. Today, we're seeing new glide computer products on the Android and iPhone platforms. The ones that succeed I believe will be those that invest not just in powerful features, but in the overall pilot's experience.

I agree that a remote stick control would be a nice thing. I don't agree on your statement about touchscreens or gestures though. I have been using them for at least two years now and they work very good actually. I don't have to go through the menu anymore to open up the waypoint list or things like that. When I had my old PDA I could use the hardware buttons to zoom. With the Streak I can only use the volume buttons to do this, but using the gestures feature has simplified this quite a bit. The touchscreen is also great for tapping things on the map and interacting with them. You simply can't do that without a touchscreen...

Kirk, please try to convince manufacturers to open up!

> need for touchscreens altogether.
I have been trying to get open-ness from a lot of manufacturers, because I wanted
to interface with their equipment from software that I wrote.
Some manufacturers opened up! I can remotely control a Borgelt B400 second-seat
variometer and I am allowed to spread the specs and code to do so. This is great,
since I now have an old-skool dial which I can control from software.
Some opened up, but preferred I do not publish their specifications. This is
mainly (from memory) Funkwerk. I got the specs for their TRT800 and ATR833.
Others did not want to share anything. This was mainly Trig, which is unfortunate
since their equipment is nice hardware-wise (radio and transponder can be
splitted, which is nice in a metal glider).
I've also heard things from Becker and Dittel, but I'm not sure in which category
they fall.
My point is: open-ness is something we will all benefit from, but manufacturers
seem to hesitate.

XCSoar is that, if conditions are good enough to complete a task, you
don't need to touch them while you're in the air: both manage the zoom
just right as you approach and leave a turnpoint and don't bother you
with airspace you aren't going near.
I very much like the way LK8000 maintains a dynamic list containing the
task's turnpoints, 'home', the best alternate airfield and the last
thermal. The ability to select any of these by dialing round the list
makes it easy and intuitive to skip an unreachable turnpoint, abandon the
task or head for the nearest airfield.

Precisely. There's a good reason fighter sticks and throttles have
over 20 buttons, switches, and pointing devices on them - taking your
hands off the controls is not always even possible, and is rarely
desirable. If some smart person could figure out how to interface a CH
Fighter Stick to my Oudie, I'd be in heaven! As nice as the current
crop of glider PNA/smartphone software are, they are increasingly
driven by the need to work around a touchscreen-only interface - which
means they have to be mounted close to the pilot, which means they are
limited in size to no more than 5 inches, realistically. Which is a
hardware dead end, eventually. But rightnow, the cost difference
between the large, remote controlled displays and the smaller, touch
controlled displays is such that the majority of pilots are, by choice
or necessity, going to opt for the touch devices.
A more specific question: Naviter, if you are reading this, since the
LX9000 and Ultimate versions of SeeYouMobile use hardware controls
with no touch screen, is there any way to use the same stick controls
they use to interface with an Oudie?

I think if you try to design a good joystick system for a glider, you'll find it is a challenging (and rewarding) task. You need to balance the learning curve (a glider pilot may not spend hours each night memorizing the layout of a complex joystick, he may not be able to practice with a really complicated joystick outside of the cockpit) against the value of one button access to critical functions. (Maybe a good design includes a simulator joystick that the pilot can hook into Condor to practice with.)
>> over 20 buttons, switches, and pointing devices on them
The same challenge of designing a good joystick for a glide computer applies to designing a good touch screen for a glide computer. (1) what are the critical tasks that need to be one-touch (one button) access? Are there four such critical tasks, five, fifteen? Depending on how you analyze the needs of the pilot, the number of buttons on your joystick (or the number of one-click areas on a touch screen) will either be few or many. (2) after you've identified the critical functions, how do you account for pilot personal preferences? will you allow some sort of customization of the buttons (shortcuts to whatever the pilot thinks are his critical functions)? Maybe you have "themes" from which a pilot can select. This is another challenge -- a really flexible and customizable system adds complexity to the overall computer (regardless if a touch screen or a joystick).
So I "stick" to my original view that whether it's a joystick or a touch screen matters less than the effort that goes into the overall design. The goal is a flight computer that balances power with flexibility with ease of use. To the best of my knowledge, scant research has been accumulated about this aspect of glide computer design.

With the computer doing most of this itself, a few over ride switches are all that is needed to deal with exceptions.
