But Rainbowduino support improved as well. I fixed lots of bugs and implemented requested features. Now you can control the display brightness, save up to 10 frames onto the device and serial port is auto detected. In general, I defined an basic API to communicate with the devices, which allows you to add more devices easily (e.g. monome!). With that, all Rainbowduino stuff is moved in a separate Rainbowduino Processing library.

Yay, I finally released my Launchpad Processing Library. Please see it’s project page and source at github.

Videos & more are coming soon. (Yes, this includes an updated mtXcontrol Version with Launchpad support!!)

See MacGPG and GPGMail for more…

UPDATE: btw. to get GPGP work with gmail, check out FireGPG, a nice plugin for Firefox, which works perfect for me on Mac OS X. Unfortunately I haven’t found any Safari solution yet…

For that, I needed Serial communication within ruby. Thanks to ruby-serialport first steps went quite well. I could write OR read from and to Arduino easily. But for some reasons, writing AND reading using the same instance didn’t work out.

I used a simple ’send-input-back’ sketch on the Arduino side. So every byte I’m sending is returned back. I checked with the Arduino IDE Serialmonitor and a simple Processing script – everything worked alright. But using ruby it was different. Writing to serial port worked okay, but reading from it was just random. Sometimes I read the response, sometime I didn’t – really, really weird. Some headaches and a lot of time testing I finally found the solution: just open two instances of the serial port. One for sending, one for reading – and, surprise, surprise – it works perfect! Who would have guessed that!? Strange..

// To be completed
require 'serialport'
port_write = Serialport.new()
port_read = Serialport.new()

Ok, continuing hacking, more soon…

(*  small apple script to save rating into grouping field and
   vice versa. Perfect to persitent store your rating witin the file
*)

tell application "iTunes"
	repeat with stars from 1 to 5
		set rating_value to stars * 20
		set group_name to "" & stars & " Stars"

		set sel to (every track whose rating is rating_value and grouping is "")
		repeat with aTrack in sel
			tell aTrack
				set grouping to group_name
			end tell
		end repeat

		set sel to (every track whose rating is 0 and grouping is group_name)
		repeat with aTrack in sel
			tell aTrack
				set rating to rating_value
			end tell
		end repeat
	end repeat
end tell

Btw. for each Star rating I do have a smart playlist which allows me to find those quickly.

module Kernel
   private
   def this_method
     caller[0] =~ /`([^']*)'/ and $1
   end
end

for Ruby >= 1.9 you can uses this:

module Kernel
   private
   def this_method
     __method__
   end
end
