Struggling with the method for obtaining a suitable remote control on the weekend, and I think I solved the problem.
I plan on using an IRMan like device and
Girder to control the system.
After toying with my thinking cap, I ventured down to the local electrical discounters (Harvey Norman Homestarters, for the Australians) and asked if they had any orphaned remote controls - controllers that didn't have anything to control. They had a drawer full of them!
After picking one out (see below), I asked "How much?"
Seems that it couldn't go through the register, and was practically worthless to them, so I suggested a 6 pack in exchange - deal done
C!
