blink1-status-hub v0.1.2

blink1-status-hub

HTTP REST API server in Node for blink(1) devices

Supports plug and unplug of blink(1) while server is running.

Uses new node-hid@0.5.0 so works with Node 4.x.

This code base was based off of node-blink1-server. I wanted to build something that was geared more towards productivity enhancers vs just a play tool. I wrote this with the expectation that I would be performing most of my long running tasks on virtual machine. Running this on a Raspberry Pi or Beaglebone would also be a cool use.

I use /dnd to show that I'm currently on a phone call (busy light) and I use /done and /fail for work tasks. The Blink(1) has 2 LEDs.

Installation

Install globally and use on the commandline:

npm install -g blink1-status-hub

# starts server on 127.0.0.1:4949
blink1-server

# starts server on port 127.0.0.1:080
blink1-server 8080

# starts server on 4949 using en0's IP (osx)
blink1-server 4949 en0

# starts server on 4949 using eth0's IP (linux)
blink1-server 4949 eth0

# starts server running on local parallels VM host adapter
blink1-server 4949 vnic0

Or check out and use via npm:

git clone git@github.com:902Labs/blink1-status-hub.git
cd blink1-status-hub
npm install
npm start 4949

  • rgb -- hex color code (e.g. "#ff00ff") required
  • time -- fade time in seconds (default: 0.3)
  • ledn -- LED to control (0=both, 1=top, 2=bottom; default: 0)
• /blink -- blink a color, query args:
  • rgb -- hex color code (e.g. "#ff00ff") required

My setup of choice

I run this service on my host machine. My host and virtual machines all have aliases created in ~/.profile that allow for quick execution

My OSX Laptop/Parallels Host

getIP() {
	ifconfig $1 | awk '$1 == "inet" {print $2}'
}

alias blink-off="curl -s \"http://$(getIP vnic0):4949/clear\" > /dev/null"
alias blink-clear="blink-off"
alias blink-dnd="curl -s \"http://$(getIP vnic0):4949/dnd\" > /dev/null"
alias blink-free="curl -s \"http://$(getIP vnic0):4949/free\" > /dev/null"
alias blink-done="curl -s \"http://$(getIP vnic0):4949/done\" > /dev/null"
alias blink-fail="curl -s \"http://$(getIP vnic0):4949/fail\" > /dev/null"

One of my virtual machines I run docker from

HOSTIP="10.211.55.2"

alias blink-off="curl -s \"http://$HOSTIP:4949/clear\" > /dev/null"
alias blink-clear="blink-off"
alias blink-dnd="curl -s \"http://$HOSTIP:4949/dnd\" > /dev/null"
alias blink-free="curl -s \"http://$HOSTIP:4949/free\" > /dev/null"
alias blink-done="curl -s \"http://$HOSTIP:4949/done\" > /dev/null"
alias blink-done="curl -s \"http://$HOSTIP:4949/fail\" > /dev/null"

How I use it

# simple example
> sleep 5; blink-done

# with error example
> sleep 5 && cd /imaginary-folder && blink-done || blink-fail
