Wow! Modeller, yer a man after my own heart. Take a look at http://www.rocrail.net
. All open source, and some have been using arduino with DCC there, along with Rocrail's excellent C/C++ software.
That's great, I didn't know about rocrail. I do have a USB DCC interface that I will be using with JMRI at some point to control the layout. I wonder if the Admins would consider starting a board where members could post project threads that use Adafruit products? I don't specifically see a "My Project" board. This would not be necessarily for help but just to show the progress of a project. I think that would be really interesting.
For example if you were making an Arduino controlled coffee pot you would post all your progress there. I just got my ammeter and voltmeter from the Adafruit store and when I get it installed on the layout I want to show it off here somewhere. Hey you never know what ideas you can generate (and products you might be able to sell) if others can see what your are building.
I was feeling a bit out of place around here until I found your post, rail on my friend!
Hey model railroaders were makers before makers were cool. 8)
Also, how about an off-topic community area where people can get to know one another outside of the technical stuff? That would be good for this type of back and forth because I know it's off-the original topic. How about it Admins?
