Node-RED is a tool for wiring together hardware devices, APIs and online services in new and interesting ways. It build on top of Nodejs
With this, PINE64 going to be more interesting. 
Tested with PINE64 2GB(1GB and 512MB shall work well, anyone with this please help to test out), Debian Base(Others Debian built shall work well, some Debian only support Nodejs 4.x).
1) Install Nodejs
sudo su
cd /home/debian
mkdir src
cd
wget https://nodejs.org/dist/latest-v6.x/node...m64.tar.gz
tar -xvf node-v6.8.1-linux-arm64.tar.gz
cd node-v6.8.1-linux-arm64
sudo cp -R * /usr/local/
cd ..
rm -rf node-v6.8.1-linux-arm64
2) Install Node-Red
sudo npm cache clean
sudo npm install -g --unsafe-perm node-red
3) Boot time auto start
a) Create bash file for node-red service
sudo nano /lib/systemd/system/nodered.service
Code: # systemd service file to start Node-RED
[Unit]
Description=Node-RED graphical event wiring tool.

echo -e '\033]2;'Node-RED console'\007'

if [ "$nv" = "v0" ]; then

echo -e "Use \033[0;36msudo systemctl disable nodered.service\033[0m to disable autostart on boot"
echo " "
echo "To find more nodes and example flows - go to http://flows.nodered.org"
if [ "$nv" = "v0" ]; then
echo "You may also need to install and upgrade npm"
echo -e " \033[0;36msudo apt-get install npm\033[0m"
echo -e " \033[0;36msudo npm i -g npm@2.x\033[0m"
fi
sudo service nodered start
echo " "
sudo journalctl -f -n 0 -u nodered -o cat
c) Create bash file to stop node-red
sudo nano /usr/bin/node-red-stop
Code: #!/bin/bash
echo -e '\033]2;'Node-RED console'\007'
echo -e "\033[1mStop \033[38;5;88mNode-RED\033[0m"
echo " "
echo -e "Use \033[0;36mnode-red-start\033[0m to start Node-RED again"
sudo service nodered stop
echo " "
exit
d) reload systemctl daemon
sudo systemctl daemon-reload
e) create auto start link
sudo systemctl enable nodered.service
4) Start Node-red without reboot
sudo systemctl start nodered.service
5) View node-red log:
sudo journalctl -f -u nodered -o cat
6) Configure node-red settings and install node
After first time start up, node-red will auto created a system folder at /home/debian/.node-red
To configure the setting, /home/debian/.node-red/settings.js
To install node, /home/debian/.node-red/node_modules
Default setting node-red will use PINE64 host name to generate flow file. /home/debian/.node-red/flows_pine64.json
If you will change host name, update the "flowFile" path in settings.js
a) to generate password protected
npm install -g node-red-admin
node-red-admin hash-pw
(Enter your password, it will return encoded password string, copy this string)
b) Famous Dashboard UI
npm install node-red-dashboard
c) Useful scheduler node
npm install node-red-contrib-bigtimer
There are thousand of node & flow at here.
after install new node, restart node-red.
sudo systemctl restart nodered.service
7) After all done, you will able to access node-red at browser (Default will use port 1880, can be update in settings.js)
http://[PINE64-IP-Address]:1880
8) Create a sample flow. You can import the this sample flow at Menu(Right Top Corner) -> Import -> Clipboard
Code: [{"id":"60ba3a72.b24c54","type":"ui_button","z":"5bd1466.b4e63b8","name":"","group":"7e934c94.882ef4","order":0,"width":0,"height":0,"label":"Click Me!","color":"","icon":"","payload":"","payloadType":"str","topic":"","x":188,"y":93,"wires":[["529c0ec4.837a7"]]},{"id":"529c0ec4.837a7","type":"function","z":"5bd1466.b4e63b8","name":"","func":"var d = new Date();\nmsg.payload = d;\nreturn msg;","outputs":1,"noerr":0,"x":326,"y":90,"wires":[["29ee44ea.ad52ec"]]},{"id":"29ee44ea.ad52ec","type":"ui_text","z":"5bd1466.b4e63b8","group":"7e934c94.882ef4","order":0,"width":0,"height":0,"name":"","label":"Current Date","format":"{{msg.payload}}","layout":"row-spread","x":542,"y":95,"wires":[]},{"id":"7e934c94.882ef4","type":"ui_group","z":"","name":"Hello PINE64","tab":"1680a81f.a5aec8","disp":true,"width":"6"},{"id":"1680a81f.a5aec8","type":"ui_tab","z":"","name":"Home","icon":"dashboard"}]
9) This sample flow using node-red-dashboard, you can access the UI at http://[PINE64-IP-Address]:1880/ui/#/0
Hope you guy enjoy this.  Have fun!!!

I have problem related on internet connection in Android x-86 version 5.1 (Lollipop) and version 4.4 (Kitkat). I run that android emulators on VM-ware.
I use android-x86-4.4-r5.iso for Kitkat and android-x86-5.1-rc.iso for Lollipop.
I have internet connectivity and I can use web browser for both android emulators, but I cannot download the APK files.

hello everybody. Today I finally managed to boot up my pine 64 but kodi was very laggy. I looked around on the forum and found that there was missing hardware acceleration. So my question is:
- is there working hardware acceleration
- is there an image of linux with hardware acceleration
also I dont want to use android to use kodi as I had other things I want to do with linux so if there is not I just wasted my money.
thanks and sorry for bad english
