Super project Bill, I have been wondering about home made dead rail ever since I build a Geof Bunza arduino based DCC+ system. That works well but I am going to pursue this idea, great work
Great job, nice to see youngsters getting into engineering you will go far. You remind me of me at 16. LOL Your idea of cheap is a bit different from mine though, some of the stuff in your BOM like UNO for $20 is high a clone can be bought for < $5 including P&P (I'm real cheap) anyway Great Job
Oh yeah I've done this in Skipton... juice running down chin with nice pint of fine Yorkshire ale.. Heaven. :)
If this is running on mains power 120v US or 240 UK you need to ground the conduit. This should not be attempted by anyone not understanding why this is necessary
