A couple of years back I designed a simple buss feeder PCB for my layout. I ended up producing a batch and selling them through my website. I haven't had any in stock for a while. Mostly because they sold slow towards the end and I really couldn't sell them for a great price. Fast forward, I have a new batch of boards and I was able to drastically reduce cost, so I am offering them again. At a better price and at more usable quantities. If you're interested in them, I have updated my website with the pricing, pictures and a new helpful diagram to explain how they are used in the most basic way: http://rpc-electronics.com/mrrtrackfeeder.php
Jason, that looks like a great idea. Can you tell me what gauge wire the connectors handle? (both the buss wire and feeders)
