  Is it possible to have more than one screen?
Posted by: MostHated - 03-02-2016, 11:48 AM - Forum: POT modules - Replies (2)

Hello all, I was wondering if there was a way to have more than one screen? I have seen on the Rasp Pi people have used USB to HDMI out adapters with success, but they take away from compute resources and such, is there a way to have more than one screen (for extended desktop, not just mirror)? I have seen "video walls" using clustering, but I don't want to simply play a video, just extend a desktop.

If anyone knows of any way, I would appreciate it!
Thanks,

**Edit, is it possible to use both the 7inch screen connected to the board as well as an HDMI monitor at the same time for dual monitors?

Hello, I saw in another thread that they said if there was enough interest in a larger screen,  they would consider making them. I figure this would be a good way to gauge the interest.


  [REQUEST] Youtube video tutorial for dual-install Ubuntu + Remix OS
Posted by: 7777777 - 03-02-2016, 05:38 AM - Forum: Getting Started - Replies (14)

Seems we would be receiving our Pine 64 now  Big Grin

Now, the OS seems an issue due to small developments and may take some time until a stable release is done? I miss kind of clear software support section by Pine64 staff

I request someone to publish (when possible) a step-by-step Youtube tutorial for a dual install of Ubuntu 16 + Remix OS 2.0

I think a minimum sd card with 16GB would be ok

Thanks

Lightbulb Server for filesharing to computer?
Posted by: LordCanti - 03-01-2016, 10:37 PM - Forum: Pine A64 Projects, Ideas and Tutorials - Replies (3)

So I want to make a low power server for my pc and phone. All I want to be able to do is create a cloud like thing with a graphic UI, but I don't know where to start. VNC is not what I'm looking for though, it only controls, and doesn't allow you to download from what I see.

Any help would be appreciated. Big Grin

  Low power headless operation?
Posted by: rubenk - 03-01-2016, 01:57 PM - Forum: POT modules - Replies (9)

We are currently using a very expensive but low-power arm sbc  for long term field monitoring and control (embedded hardware). Has anybody looked into how low the power could go if we turned off power to the accessories that wouldn't be needed like HDMI video to audio in and out, SATA, camera, things like that?  I think we could even get by with running on a single core.  This is probably far outside of the intended audience of the board but that is our application and I thought I would ask. 

 One thing that is a definite kick in the nuz  is that there is no onboard eMMC.  I have plans to keep this in the field for months at a time even up to a year between service intervals.  I'd rather have one place to store the data and another place to boot the OS but such is life. There is an ODROID board that allows you to have onboard be MMC but  I don't know very much about it or about power consumption. 

 So, the final question: is it an ill-fated attempt to try to take the power out of the pine 64? If so, does anybody have any recommendations?


BTW power on our current board is about 0.5 Watts at idle

Hey folks,

This is meant to give an idea of backers who have received their boards, so if you've got yours, post a reply with your batch and when you received it.

I'm a February early-bird backer and I'll update this post after mine arrives.

EDIT: Based on the latest update, looks like my board is going to be delayed because I added some accessories (Camera, RTC and WiFi/Bluetooth modules). That's disappointing. If this information was available earlier, I wouldn't had added any accessories to my pledge.


  Grove Hat

Hi

Are there any plans to provide a grove hat for grove sensors?

Lots of sensors providing lots of possibilities for the pine... ;-)
