Interesting project. I am not much of a web programmer, do you have your webinterface control code posted somewhere ?

Cheers,
Barry

Hello Anat and everybody,
I am very interested in this project and follow for 3weeks.
I just ordered a raspberry pi.
I'd like to know if it is possible to connect a DMK cam on the raspberry pi. Would there be any power issue with the cam ?
kind regards
Pat

Hello,

I will release the codes soon after some tests from beta testers. Recently, I use the MK808 dual core Android TV stick for this project because it is much faster, smaller and cheaper overall. I am not sure about DMK cameras. To use it for autoguiding, you may need to look at GoQat which supports the camera.
http://canburytech.net/GoQat/index.html
I successfully compiled GoQat on Raspberry Pi some time ago.

Best regards,
Anat

Anat,

Are you running MK808 on Linux or Android?

I am assuming for this project, you are fork-lifting the whole thing to make it Linux for easier to support??

BTW, if it ends up to be not the optimal solution, one can always change it back to XBMC video player .
On that front, will RaspberryPi or MK808 be a better dual-use solution?

Clear Skies!

Hello all,

I have tested my all new raspberrypi to drive my orion atlas mount using skysafari. It works very fine. But the 2 usb ports are occupied one by the usb wifi dongle the other by the Raspberry which handle the mount. To answer a question I have seen somewhere: the handle is needed to make it works.
So there is no other room to connect a cam.
The amount of the installation to drive an Orion Atlas mount is as follow:
raspberry B 42
box for rpi 10
wifi dongle 10
usb/RS232 14

for a total of 76 (100$) which is the half price of the skyfi orion device (in Europe).

Unfortunately I have read somewhere that the usb inteface is unique and the 2 plugs share the same interface. So there is nothing to wait in term of performance. But maybe it is sufficient for autoguiding.

Anat you are true, the MK808 looks to be a better alternative, wifi, bluetooth are included in device. But unfortunately there is only one usb plug. It would have been fun to make acquisition with the same device as the one that autoguide and drive the mount. But it seems not to be done even with the MK808.

Ouch, that MK808 has so many cousins:

Buying the right type (for picuntu) would be quite a challenge.

808's little brother info MK802

http://en.wikipedia.org/wiki/Android_Mini_PC_MK802

Anyway, $40-ish price tag (808 cloned version) for a 1.5GHz A9 quad core, 1GB RAM, 8GB NAND flash, HDMI out, USB, USB OTG, WiFi, and Bluetooth all included is not bad. Not bad at all.

Yes. I run Ubuntu (PreAlpha 0.3) on MK808. It is very stable. MK808 is a better solution.

The best RK3066 module in my opinion is the original MK808 with the RK901 wifi chip. The wifi chip works in linux for client, access point, and adhoc modes. I got several MK808 sticks from
http://www.geekbuying.com/item/MK808-Dual-Core-Android-4-1-Jelly-Bean-TV-BOX-...

It is the right one.

Congrats for the Skyfi setup !
Both Raspberry Pi and MK808 works with a powered usb hub. In my setup I use:
QHY6 for autoguiding
QHY8L or DSLR for image capturing
USB-serial adapter for mount control
USB sound adapter
connected to a hub without any problem.

Anat, I have a question for you, what you done to successfully compile GoQat on the raspberry.
Thanks for your answer.




These are steps to compile GoQat:
sudo apt-get install gawk
sudo apt-get install libgtk2.0-dev
sudo apt-get install libgoocanvas-dev
sudo apt-get install libxpa-dev
sudo apt-get install saods9
sudo apt-get install grace
sudo apt-get install libunicap2-dev
sudo apt-get install autoconf

>>> Install GoQat
tar -xvf goqat-0.9.8.tar.gz
cd goqat-0.9.8
./configure
make
sudo make install

I am ready to release the source codes. Thank all testers and developers for your support.

https://sourceforge.net/projects/iastrohub/

Now a tablet can control the autoguider, CCD, DSLR, and mount via a tiny hub I recommend MK808 (original with RK901 Wifi chip).

Best regards,
Anat

so have you tried openPHD again? it seems like they have made a lot of progress recently.

I have never tried openPHD after using Linguider. Linguider is super fast on Arm devices.

i'll check it out. just browsing thru the files you've uploaded, it seems like mount control is done thru CdC with the INDI interface, is that correct?

Can it control an SBIG camera?

i have been looking into this - i don't think so. however, hacking in sbig http support might be "easy", but that only works on STT and STX cameras.

i think the main problem is that INDI is way behind ascom. maybe these little single-board computers will change that though.

Darn. I'm sure hacking in an HTTP server wouldn't be too bad. I just find SBIG's lack of an ASCOM driver to be a real PITA.

well, it's easier because it's an http client. it could probably be done with a perl script, actually.

and libcurl is really good for getting http support into a program... like phd.

what does an ascom driver buy you for a camera? meaning, are there camera control packages out there that only interface with ascom-compatible cameras?
