4. Nokia 770 configuration

The Nokia tablets come in three models: the 770, N800 and
N810 .
 All will work as a controller. The later models have more
memory
and better internet features like Flash 9 compatibility. They also cost
more. Right now on Amazon.com, the 770 runs $200, while the N800 runs
$300
and the N810 runs $385. I picked up a used 770 for $85 with
shipping. They run Maemo, a Linux port for Nokia devices. I am new to
Linux, but managed to get everything configured. The instructions start
here: Papywizard
Installation Wiki

I will cover the more complicated 770 install, as that’s what
I did.

Flashing the new OS

The 770 ships with Maemo OS2006, which can not support the python,
needed to run Papywizard. You need OS2007
HE (HE=hackers addition). The download requires you enter
your Nokia serial number. I used the Latest Fiasco version.

You will also need a flasher,
with versions available for OS X, Windows and Linux. I used 770Flasher.app
v2.0 which
is an OS X gui, but had trouble with it not finding the tablet, so I
switched to the
Nokia Internet Tablet Software Update Wizard ,
which worked fine. You run
the flasher program, selecting the new OS file, then you
power up
the tablet while holding down the home button. A USB symbol appears on
the screen, and away she goes.

Note: I think my troubles came from trying to power up the tablet after
I had been charging it with the power off. Apparently, it goes into a
special power state when charging, and should be turned on
before
removing the power, and then turned off.

Adding software to the Nokia 770

I next needed to set up the 770 with the repositories containing the
applications I wanted to install. While you can install applications
directly from the files, if you use repositories and their catalogs,
you can check for updates and install them more easily. This is pretty
convenient for things like Papywizard, which is getting updates pretty
regularly. You will need access to the internet on your Nokia, which
means a Wi-Fi connection to download and install the
applications.
Otherwise you could download the applications onto the rs-mmc card
using another computer and install from there, but it would be a hassle
for sure.

Getting the repositories

You can install the repositories manually by going into
the
applications manager (see screen capture),

Selecting applications catalog in applications manager

and selecting Tools>Application catalog from the drop down menu.

Selecting applications catalog in applications manager

You can manually enter the catalogs as shown in the
Papywizard
Installation Wiki. Later you will install some applications
contained in these repositories.

Better yet, you can go to this website on your Nokia, and find
the ones you will need.

Scroll down and click on the following repositories/catalogs to add
them:

  • Debian Nokia repository (listed as the Extras
    catalog in the Papywizard installation wiki) for accesss to the python
    runtime
  • Maemo-hackers (listed as the Hackers catalog in
    the Papywizard installation wiki) for access to osso-xterm
  • gbiloba.org (Papywizard) for access to Papywizard:

Installing the Applications

Now you can start installing the applications: godmode,
osso-xterm, python
and Papywizard. (I have emphasized the
application names in this section for ease of reading.)

First get and install godmode
 which
does not have a repository, by clicking this link from your Nokia. (You
could also save the file on your computer and move it to your Nokia.)

Next use the
Application
manager
to install osso-xterm You should be able to find osso-xterm under Web catalog>Browse
installable applications on the initial application
manager page. You will need this program to set up the python runtime.


If you can’t
find it…

I had problems getting repositories
to update with a list of
applications. Instead I got “(no applications available)”.
The best thing I found was to disable them one at a time
 in the Application
manager>Tools>Application catalog>(choose
catalog)Details and select Disable to find the
one that was not responding. (Basically, the Nokia goes to
a server, and if the server is busy or down, it errors out. I
would then update, and browse the applications in the web section
of application manager to see if I had osso-xterm. The installation
itself went
fine. 
Once you get osso-xterm running, you can also update the
repositories manually:

  • Start X Terminal
    (osso-Xterm). It is found in the Extras folder.  (Along with
    Papywizard after it is installed)

    • Running X terminal

  • typing this gives root shell : sudo
    /usr/sbin/gainroot
  • typing this updates repositories: apt-get update

you should install python while you are
there:

  • typing this will install python: apt-get
    install python2.5-runtime
  • type exit
    to leave the Xterm shell 

If the repositories show up fine for you, skip the apt-get update step
and just install python.

Now go back into Application
manager>Browse installable programs
to install Papywizard.  In
having problems with repositories, I
found that programs would appear and then disappear as different
repositories errored out. Keep trying, and you will find the program
you need. Give it some time to try to connect too. (A couple of minutes
won’t hurt.)

You should be able to run Papywizard now. You can check for updates by
clicking the button in Application
manager
under “browse
installable applications“.
You can explore the software without having an operational head unit.
It might be a good time to read the users guide.

  2. I was thinking i would use my laptop be cause i want to use remote contorl software for the rebel xsi. would it work if i used a usb to ttl converter cable into a usb server on top of a 50′ pole with a usb router on the ground?

    would appreciate your thoughts on this

    thanks,

  3. This is amazing! I have a question. If I used a fish eye lens with this setup wont the shots have a portion of the orion showing in it?

  4. Milo – I use a 10.5 mm fisheye and it doesn’t catch any more of the Orion than anything else, if you have it set up correctly. Any lens setup will show the bottom (nadir) if you shoot 360 degrees. People either crop it out or shoot a nadir shot by hand and stitch it in separately. Though you might suspect that the upright would show up when using a fisheye, it doesn’t, at least for the 10.5mm. There is an example with of a stitched panorama with the Orion showing here. I use a method where I take 6 shots around at -15 degrees and the zenith or top shot.

  5. Chris – I like the pole setup idea. My main concern is Papywizard being able to resolve the Orion through the complexities of the hardware and the control software possibly conflicting. Some users are direct wiring a laptop to the orion, while others are using a bluetooth antenna to boost range, so those are also possibilities. I think you should go to the source for answers, as Papywizard v2 may have camera control, or at least picture acquisition features. Head over to the Merlin/Orion forum on Autopano.net. There are more folks over there thinking about this stuff. Also check out this thread discussing the version 2. Panning time lapse panography is another potential feature.

  6. Excellent review!

    Your trigger cable is not defective, mine is also non-conductive in the left signal section. It’s made especially for Canons though.

    I am beginning an experiment with a “Wi-Fly” wireless to serial adapter component, which will (hopefully) allow control of the Merlin over a standard WiFi network. What’s nice about the Wi-Fly is that it contains a voltage regulator on-board, so no need for power supply electronics. Together with an Eye-Fi memory card I would be able to drive the Merlin from across the street and see all photos the moment they are shot.

    Now that would be geeky, don’t you think?

  7. The cable is not defective, just a PITA. I need to have it shorted for use with the Merlin, but stereo for use as a “normal” remote. I am trying a stereo to mono 2.5mm adapter at the moment, and it seems to work. Otherwise I was going to add a switch.

    I love the “Wi Fly” possibilities! The new Papywizard has some tethered shooting functions best utilized with a PC. The only issue is that it is still focused on bluetooth. I am not a huge fan of the Eye Fi cards, since last time I looked they transmitted images to your computer via their server, which means you need internet access, not just your local network for it to work.

    I’d love to hear what you come up with.

  9. Thanks DrSlony for the Autopano link note- while I had the right link in the Resources list, I have now corrected the link in the article.

  10. Hi,

    great review and thanks for sharing.

    I am interested in how you have attached your camera, and if you indeed, managed to use your Arca-Swiss mounts (I use RRS gear as well). I am thinking of using a slightly larger camera, either Canon 1D or Nikon D3. Do you think this will pose a problem with NPP?

    thanks

  11. Thanks for the feedback. I used my RSS MPR-192 and some mini clamps for a while, but ultimately went back to using the bracket that came with the unit. In future I will need to get something machined. (A crown that I can bolt a miniclamp to and a thinner rail perhaps.) The orion/merlin has enough clearance for a D80, but getting a good NPP set up for larger cameras is impossible without major modification of the crown. If you are doing gigapans with a telephoto you can mount the camera in landscape orientation and have better luck, but you will still have issues with clearance. Anything with a vertical grip would be a headache. My recommendation would be to find a used consumer body to use for this project. Less to carry and less headaches trying to set it up.

  12. Amazing! I have been doing pano work for a couple of years and learning it all alone! so good to hear the experience of others.
    I have a Milapse head and also a mechanical pano head (Panosaurus) I waant to go robotic though because I want to do some stop motion and other things like that.

  13. It has been very interesting to watch the growth of interest in these motorised heads. While the Orion/Merlin is a good value – I have several friends who are looking into building their own machine for better accuracy and function. I think they have more fun making the contraption than taking the pictures.

  14. Hi, this is great,
    Thanks BeeZed and everybody.
    Could please please someone help me regarding the Merlin?
    I’m new to this and would like to try to remotely control the Merlin mount, on a first instance via Ethernet, then with the bluetooth.
    Can I use a simple RJ11 cable connectors and put a RJ45 to one end?
    Which connectors/colored-wires should I connect on the Ethernet plug?
    Thanks

  16. Bruno – I have no experience conrtolling the mount beyond using papywizard. AS long as you can generate serial commands, you can probably get it to work.

  17. The best information is on the Autopano forum devoted to this head, listed in the post. The commands are summarized on the Papywizard wiki. The whole point of the project is to remotely control the robot head. With a little extra hardware connection you can control the camera as well.

  18. I’m putting together one of these units, and I’ve been checking all over the place, but I haven’t been able to find out what value resistors I should use, and where they are connected on the BlueSmirf board. I know that the TX/RX pins are tied together on one side (I can see that on your picture), but are the resistors connected to the board at another point near the other end (a ground)? I sure could use a better picture!

    Thanks for all the other information. I was ready to pull the trigger on a GiggaPan and try to work around the problems. This is a much better solution (and it lets me find a use for the N810 sitting in the closet).

  19. One resistor is soldered to the RX-0 pad on the blue smirf, and the other to the TX-0 pad. They are only bent to run parallel to the board because of size constraints in my project box, so that is a little confusing. This picture does show the connection to the board (click to enlarge). The resistors are 220 ohm as listed on page 2. I hope that helps.

  20. Does anybody have a list of all the MERLIN Commands ?
    Looking for this desperatly !
    Havend found them in the Papywiki.

    Thx neix

  21. Hi, i scanned the web for a cheaper telescope head and i find this seller:

    MERLIN Panoramakopf mit Motorsteuerung

    that sell this prodoct at 159 euro.

    So i conctaced them to ask some information about it. This the reply:

    “Yes, we have Merlin for 159€ (only head, without tripod and without L-Shape).
    It is the NON-GOTO Version, you can move with 3 differently speeds, but you can not make automatically object-position.
    It is optimal as panorama-head for panoramaphotography and works together with papywithard software and BLTm-Modul. ”

    Inconclusion i would like to know if this product can be used like a teletrack orion.

    Will

    p.s. what’s it mean “non goto version”? is it compatible with this modify?
