The sides are in my git repo as .rsdoc and .STL files. Or you can convert anything to STL using the designspark cad software. All the master files are on the git repo. I've posted a lot of content but if you read through everything between the GIT and this thread, you will find all of the answers you need (I believe). BTW I have not even started to SEX up the case design. right now I'm just slowly making it a working design and fixing bugs from the basic "shape" concept. I've found that more or less all online posts of data and measurments are wrong. Even the AMAZON link for the LCD shows different pinouts between multi images in the pcb mask. And got your Anet A8 back on line? Looking at it I think I kind of like that design better then the ender neo I purchased from a local big box store. The plastic wheel bearings have to be very tight to steady the print tray. And the wheels are starting to wear with few hours on it. that printer has nice pillow bearing blocks spaced out and twin Z axis screws...... I might have gone for that had I seen that. I'm already wanting to change the bearings to a different setup on this ender. My Monoprice mini delta is much faster and much much better print quality from all aspects, but it has a scale issue everything is small by like 2% and its work area is only 110x110 mm :(. Beyond that out of the box my MP mini delta kicks the crap out of the ender neo for speed and quality from factory. In general .RSDOC files are source cad drawing files from designspark, .STL is well stl, and files in .DXF format are generally for cnc milling or laser cutting.

Nice hardware for NAS on usb3.0 only board.
It looks like perfect hardware for ultimate 12-bay RK3399 nas experience if combined with proper hardware

Most definitely...trying to do it over wifi could cause some REAALY bad lag

If one is running a DNS server for the LAN/WLAN - probably better to keep it on the wire

All the information you can think of on an easy and simple webgui

Even has a really simple script to download all deps and compile the program for you

Just thought you folks might be interested...if it's linux...this will work on it

PiHole works fine with most boards that are equivalent to a RPi2 for most home networks when wired up...
 
NanoPI NEO would probably be perfect for this application with current Armbian...

Isn't a pi-hole just a DNS server? You don't need multiple interfaces for that, nor do you need gigabit speeds to serve a local network.
All you'd need to do would be update the DHCP settings in your router to set the DNS server to that of the pi-hole. 
 

edit the file /etc/default/cpufrequtils 
the save and reboot:

I found the way to install, keep updated and easily uninstall plexmediaserver without using armbian-config. here is the link https://forums.plex.tv/t/read-me-first-about-server-armhf-arm64-debian-ubuntu-raspberry-pi/226567. I used the version arm64 / ARMv8 and on OPzeroplus with H5 works very well.
 

Today I swapped my old Neo2 against a Neo2 LTS 1GB in my NAS case - so I had a old Neo2 512MB free for the black Aluminum-OLED-case which I got in a drawer.
 
Now I did try to activate the OLED in 
ARMBIAN 5.67 user-built Debian GNU/Linux 9 (stretch) 4.19.4-sunxi64 Linux npi-neo2-27 4.19.4-sunxi64 #6 SMP Fri Nov 30 14:02:43 +03 2018 aarch64 GNU/Linux
First (like on a i2c-clock" I activated i2c0 in armbian-config:
 
root@npi-neo2-27(192.168.6.27):~# armbian-config System --> Hardware --> [*] i2c0 After the reboot I checked for the i2c-OLED-device and got:
 
root@npi-neo2-27(192.168.6.27):~# apt install i2c-tools root@npi-neo2-27(192.168.6.27):~# i2cdetect -y 0      0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f 00:          -- -- -- -- -- -- -- -- -- -- -- -- -- 10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 30: -- -- -- -- -- -- -- -- -- -- -- -- 3c -- -- -- 40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- --  After some trial and error(-messages) I did found the following dependencies for compiling/installing the software for the OLED-Board:
apt-get install python-setuptools libjpeg-dev  
After that I did the normal "5 Enable NanoHat-OLED manually" from
http://wiki.friendlyarm.com/wiki/index.php/NanoHat_OLED
with
 
root@npi-neo2-27(192.168.6.27):~# cd /home/guido root@npi-neo2-27(192.168.6.27):~# git clone https://github.com/friendlyarm/NanoHatOLED.git root@npi-neo2-27(192.168.6.27):~# cd NanoHatOLED root@npi-neo2-27(192.168.6.27):~# ./install.sh And after the next reboot the OLED-Display did work

The reason for this seems to be a regression or a missing commit from @Icenowy sources (https://github.com/Icenowy/linux/commits/h6-integrate-2-ugly) which has not made the jump into mainline (yet).
Therefore you either have to use the 4.18.0-rc7 kernel image (which I run two OPi 1+ perfectly fine on right now) or temporarily disable dwmac like @martinayotte did as workaround to successfully boot up the board with a kernel built from newer sources (and use a USB-Ethernet adapter).
For confirmation you can utilize a UART serial adapter to check the kernel boot for errors like "sun8i_dwmac_probe+0x164/0x518".
 
As stated mainline support has still a long way to go to better support the H6 SoC. Do not just discard the board. Just put it on the shelf and it may run fine in a couple of month.

I think I found something interesting: low consumption
 
how to change the fex: change fex settings

The OPi Zero doesnt need much power.
I only disabled the Wifi - because I do use Ethernet - with the following commands in the /etc/rc.local (I know are are also other/better ways):
 
ifconfig wlan0 down rmmod xradio_wlan rmmod mac80211 rmmod cfg80211  

Here's what I think the problem is.  The USB port on the NanoPi Neo 2 mainboard itself works well with the default UAS driver from the kernel.  But the second USB port, which seems to be an afterthought on the NAS kit accessory board, does NOT work well with the UAS driver from the kernel.  Why would I conclude this?  Because when I put the "problematic" (seeming) drive onto the other USB port (on the mainboard of the NanoPi) the problem went away.
 
Edit: I found the fix I needed, detailed here.

Here's a picture of the NAS I've set up for our small office here:
 
 

 
Inside the NAS kit aluminum case on the top is a 500GB SSD, and there are two more 3.5" drives on the bottom, in enclosures, attached with USB 2.0 cables.  OpenMediaVault uses all 3 drives.

Not an Armbian problem.
https://wiki.x2go.org/doku.php/doc:installation:x2goserver

Well ... I have a msata connected to the NAS device ... and these are the numbers:
 
Now, with a real mSATA.
root@orangepizero:~# hdparm -Tt /dev/sda1 /dev/sda1: Timing cached reads: 684 MB in 2.00 seconds = 341.73 MB/sec Timing buffered disk reads: 92 MB in 3.02 seconds = 30.47 MB/sec As can be seen .. it is a little slower than the WD Blue hard disk with my custom cable, but so near that can be a comparable speed.
 
The disk is a V-NAND SSD 850 EVO 250GB mSATA from SAMSUNG (i.e. a good device).
 
Now, the two main reasons this setup is a good one:
 
1) No spin-up electricity consumption.  Although not so detailed checking (I don't have better measuring tools), but with a USB power tester, the machine maximum consumption was around 0.80 Amp from start-up, including the hdparm test.
 
2) Look at it (picture bellow) ... no SATA cables, extremely compact.
 
About my configuration:
 
This setup has also a SanDisk Cruzer Fit USB 3.0 8G Disk (the short one on one of the USB ports --- the one is not shared with the mSATA device ---).  This is for the swap and other temporary stuff, so I don't need to degrade the OS SD card by constant rewriting there.  And a 3A power supply.
 
And it is important to add some screws on the mSATA storage card.  When you put it, the card remain at 45 degrees from the NAS device plane, so you must pull it down and keep there with "something" ... in this case, two Nylon screws with a nut between the mSATA and the NAS, and a short standoff bellow.
 
I still need to add a 5V fan and the case, and my setup is ready to go production (with my particular information system there).
 
 
 

I am pretty sure PiVPN has been updated to run on Stretch.

I wrote. 
 
 
Since I don't use it I don't know if there are any issues with Stretch. I am sure it works well with Jessie.

https://github.com/sgjava/userspaceio is my github and libgopid is at https://github.com/brgl/libgpiod

I also noticed that we don't need even plugging GND to RESET pin, unplugging the Atmega chip does everything

I use this method and it works like a charm:
 
void setup(){ pinMode(0,INPUT); pinMode(1,INPUT); } void loop(){ } Just upload this code, and connect GND to GND, TX to RX and RX to TX, then connect your Arduino to your computer, it will get a name like COM3, connect that com port, and you're in! You can also use PuTTY for connecting to the com port.

 
 

Nice
https://github.com/ilikenwf/apt-fast

I don't have a fiber/fast internet connection, and I get around 200kb/s download speed when I use normal apt or apt-get.
 
But apt-fast accelerates download speeds significantly. I go up to 1MB/s using it (I set max connections option to 16 while installing it, you'll know what I mean when you try to install it using apt-add-repository, of course, if you don't know). So I suggest you to use apt-fast in "armbian-config" or any system utility. This suggestion goes to the developers. So that we (users with no good internet connection) can update the system or install the desktop environment a lot faster and easier.
