Stop thinking of files, Ruby is about objects, it doesn't in which files
statements are, as long as they are processed.

mybot is a local variable now.

What do you mean, what happended? Does IRCBot have an conn method? What
happens if you use mybot.conn? [1]

There is no local variable mybot here. Call it $mybot if you want
global variables, but you really shouldn't want that.

Try:

class IRCCallback
  attr_accessor :bot

  def self.check_next( input )
     @bot.conn.send("PRIVMSG matt-mb :hey-o", 0)
     puts "irc callback working"
  end
end

IRCCallback.bot = IRCBot.new
