    Upgrade from Orange pi PC?

    That looks neat and essentially gives me 3 USB ports as I would be using USB-SATA adapter anyway but it's $55 USD including shipping to the UK sound good
  2. I have an orange pi PC that I use as a simple NAS (NFS, smb, iscsi) and for openVPN occasionally but want something new with GbE. What is the best upgrade that will give me 2 or more usb ports, GbE and a faster processor? With decent software support ()? I don't need HDMI or wifi but it would be a plus 512MB-1GB RAM opi zero plus? opi PC 2? Around $20 shipped ideally

    Using performance gov on opi PC with Sandisk 16GB A1 on a usb card reader Command line used: iozone -e -I -a -s 100M -r 4k -r 16k -r 512k -r 1024k -r 16384k -i 0 -i 1 -i 2 Output is in kBytes/sec Time Resolution = 0.000001 seconds.

Purchased from aliexpress ($5) but the scratch & verify sticker says it's genuine My samsung evo 64gb went read-only recently (20 months old) and then would not boot. I copied to another card and ran fsck and all seems OK. I think the later evos were not as well made as the earlier batches.
  4. I'd use this to get the HDMI output of your DSLR encoded (720p only) https://blog.danman.eu/new-version-of-lenkeng-hdmi-over-ip-extender-lkv373a/ Then a raspberry pi or pi0 to do the hw h264 re-encoding

    Soft wake up from sleep orangepi zero

    Not sure, but I don't think so. AFAIK you can only wake from IR or GPIO You can buy RTC modules based on the DS3231 which have built in wakeup alarms that you can set and trigger a GPIO on the opi to wake it

    IP Camera - CCTV omxplayer

    If you want hardware accelerated decoding you need to use mpv or mplayer. I'm not sure if you can run multiple instances and all use VDPAU edit: mpv segfaults if you open 2 instances

    Opi Zero Desktop

    I have VDPAU working on TVout on the opi zero. VDPAU only works on screen0. opizero is set to use screen1 by default, but both are configured to PAL/TVOUT. setting VDPAU_SCREEN=1 had no effect so I just changed the fex to: disp_mode=0 https://github.com/linux-sunxi/libvdpau-sunxi/issues/32

    Did you have any success?

    Opi Zero Desktop

    I updated to head and recompiled and still have a black screen. Do I need to edit the kernel config? CONFIG_CMA_SIZE_MBYTES is set to 16 edit: appears not, this is from dmesg cma: CMA: reserved 128 MiB at 58000000 Kernal Command Line: ... cma=96M

    Opi Zero Desktop

    Thanks. Desktop works but HW video decoding doesn't, I just get a black window - the same video works on my OpiPC. Does VDPAU support TV out/CVBS? Using: Armbian_5.35_Orangepizero_Debian_jessie_default_3.4.113_desktop

    Opi Zero Desktop

    How do I get a desktop running on this (legacy)? It only outputs a shell on the video out Additionally, is the hw video decoder enabled? Armbian_5.30_Orangepizero_Ubuntu_xenial_default_3.4.113
  13. Network block device support is not included in the 3.4 kernel on opi PC CONFIG_BLK_DEV_NBD Could this be enabled by default in a future update?

    Tiny 3$ lcd on orange pi

    I'm not having any luck getting an image. I've connected mine (same model as Neo) as shown in the first video. If I don't connect the backlight (3v3) then the screen flashes faintly sometimes when using test programs. When the backlight is connected it doesn't appear to do anything - just a white screen
