No static external IP on Raspberry Pi

My Internet provider doesn't supply me with a static IP address with my broadband, so my Raspberry Pi external web address can wander if my router or connectigets reset. There are third party sites which will provide you with a static URL which follows your wandering IP address but its fun to do it yourself.

To keep me updated on the current IP I wrote a Ruby script which I run via crontab to check and Tweet me is the IP address changes.


#!/usr/bin/ruby



require 'open-uri'



require 'twitter'







twitDM = "twitter_username"







remote_ip = open('http://whatismyip.akamai.com').read



old_ip = File.open('remote_ip.txt', 'r').read







if (remote_ip != old_ip) then



    File.open('remote_ip.txt', "w") { |file|  file.write(remote_ip)}







    client = Twitter::REST::Client.new do |config|



      config.consumer_key        = "xxxx"



      config.consumer_secret     = "xxxx"



      config.access_token        = "xxxx"



      config.access_token_secret = "xxxx"



    end







    client.update("D #{twitDM} My IP address is now #{remote_ip}")







else



    puts "IP addresses match"



end

You can clone the script at Github https://github.com/alastairhm/myip it uses a Ruby Twitter API library which can be found at https://github.com/sferik/twitter to do the direct message with the new IP.

Ruby Script to send Twitter mentions over serial port

Short script to send Twitter mention messages to a serial port using Ruby and the gems twitter and serialport.

# Find your Twitter Mentions and send them to Arduino on Serial Port

require “rubygems”
require “twitter” #https://github.com/sferik/twitter for config details
require “serialport” #http://rubygems.org/gems/serialport
require “pp”


prevID = 0
puts “Setting Up Serial Port”
myport = SerialPort.new("/dev/ttyACM0",“9600”.to_i)
sleep(10)
while true
puts “Checking for mentions”
latestMention = Twitter.mentions(:count => 1)[0]
if prevID != latestMention.id
msg = latestMention.user.screen_name + " " + latestMention.text
puts “-” + msg
bytes = myport.write(msg)
puts “-” + bytes.to_s
prevID = latestMention.id
else
puts “-No new updates”
end
sleep 60
end
myport.close

Some Debug Required

First test of Twitter updates getting written to the Arduino from Ruby didn't go quite right as seen from the video below, some debugging required.

Testing writing the same message from the Arduino IDE gives the same results so looks like problem is in the Arduino code. Maybe the message is too long for the LCD's buffer?



The Twitter to Serial port Ruby script can be found at https://github.com/alastairhm/arduino/tree/master/SerialMessage

Ruby Script to get Twitter mentions

Here is a short Ruby script to check for mentions on Twitter, it uses the Twitter Gem.
Plan to use this to send messages to my Arduino, looking for a good Ruby Serial Port Gem now.
 
 
# Find your Twitter Mentions

require “rubygems”
require “twitter” #https://github.com/sferik/twitter for config details
require “pp”


prevID = 0
while true
latestMention = Twitter.mentions(:count => 1)[0]
if prevID != latestMention.id
msg = latestMention.user.screen_name + " " + latestMention.text
#puts msg.size
puts msg
prevID = latestMention.id
else
puts “No new updates”
end
sleep 60

Sending Arduino messages over serial port

Note: 1 of this post’s 6 links are now broken — mostly dead 2008–2013 feed-syndication infrastructure (FeedBurner, Gawker, AOL’s old blog network, Pheedo, Yahoo Pipes). Left as originally published.

Video of sending a message to the Arduino over the serial port which then gets scrolled on a SainSmart LCD shield.

 Idea was to use it to display tweets, just need to write the Ruby code to get the tweet and send it over the serial port now.


Here is the first version of the sketch uploaded to the Arduino.
All code can be found at https://github.com/alastairhm/arduino.git

 




// Auto scroll a message on the LCD and receive new messages via Serial port.
// Alastair Montgomery (c) 2013
// Version 1.00
 
// include the library code:
#include <LiquidCrystal.h>
#include <string.h>

// initialize the library with the numbers of the interface pins
// below for SainSmart LCD Shield
LiquidCrystal lcd(8, 9, 4, 5, 6, 7);

Remote control using Twitter

I have been thinking about running task on a Ubuntu Linux machine remotely using Twitter. Why you ask, due to firewall restriction where the machine is located I can’t get direct access to it but it has connection out to the internet.


So I thought I could send coded messages to it using Twitter and have it run certain tasks. Should be fairly easy to do in Python I thought, but what do use it for? Kicking off test runs, downloads or other system tasks?

Downloads seemed a simple place to start, why max out my home broadband usage limit when I can get the remote machine to download things off-peak.

For the proof of concept I decided to code it for using WGET and a command line YouTube down loader.

Using this Python Twitter API I was able to get a proto-type running in a short time.

Basically it should work like this,

  • I send a direct message to a Twitter account which only follows me and I follow on my main account.
  • This contains the code for type of download and the URL of the download.
  • The Python script is started by cron at scheduled times.
  • The script connects to Twitter and checks for direct messages.
  • It parses the direct message and either spawns a WGET or youTube-dl command to get the resource.
  • If its a video it then runs a command is run to convert it to divX ready for upload it to my phone.
  • If its a file then it is virus checked.
  • Finally the direct messages are deleted from the Twitter account and a reply sent to my Twitter account.
So now without physical or remote access to the machine I can queue up downloads to retrieve during off peak hours.

Now I’ve got it work, need to fine tune it to run other remote tasks, like restarting Weblogic or deploying new version of the application and running test suites.

For the longest time I refused to see the value in Twitter. Over the last six months I have changed my tune on that. Now I use Twitter primarily as a PR tool for my articles. And since my renewed belief in micro-blogging, I have found plenty of tools with which to enact with Twitter.

URL Shortening Rant


URL shortening is a great idea for Twitter’s 120 character limit but it does have its problems. Most annoying, you find an interesting link and click on it and get presented with the screen above. There is nothing you can do to get to the article you clicked on until the server load goes down.

Other problems include you don’t know what site you will end up on so can end up on a phishing site or something NSFW, although TinyURLs preview option kind of helps that problem.
