What Hacker News says?

  1. One thing I don't know how to do is encode information in pulses. That's why I use the record/replay method. There is probably a program that will convert a binary string to pulsed data (I believe 2ms chirps with 2ms gap between them?) but I don't know of it. There is a little more information on the opening signal here: http://andrewmohawk.com/2012/09/06/hacking-fixed-key-remotes...
