Adventures in Infrared – part 2

Continuing from part 1, I have replaced the IR detector in the matrix receiver and now the receiver can detect the 56KHz Austar remote. ¬†Unfortunately the transmitter is still sending out a 38KHz signal and the Austar box doesn’t respond to it.

At this point I can see two options:

  1. Build a circuit to convert the 38KHz carrier into a 56KHz carrier
  2. Replace the IR detector in the Austar box

Option 1 isn’t too hard, but it does need a bit of wiring and extra components.

Option 2 would give me the cleanest solution, but involves hacking a box that technically isn’t mine.

I am still considering my options…
