When the new firmware is released we will have a easy method of producing audio output. It would really be convenient to have a component with either a built in speaker and volume control. Or one with a standard audio jack. Either a 3.5mm TRS jack or a RCA connector would do just fine.
I have experimented with the alligator clip to a small amp that I use with my iPod, but when connected I could not communicate with my Domino. I’m guessing I was putting too much load on the analog out pin and I certainly don’t want to do that.
I would use any AMP kit fro any website and then buy a JST cable from this website… solder the cable on the kit and you are good to go. This is what we did for our demo.
