I have a proposal for you. I see your interest in MERG is strong and you have an even stronger interest in electronic projects. So, I am going to be opening a new forum for the purpose of advancing technical issues in N Scale electronics and mechanics. It really isn't limited to N Scale but due to the tiny sizes involved, it does require specialized attention. Virtually everything discussed will be useable in all scales.
What I need is an administrator for the forum besides myself. If you are interested, contact me. On the mechanical side, there will be no shortage of technical issues to discuss. Electronics will be mostly focused on DCC and other control methods.
