Hi all,
What I have is pretty simple starter project to start me on my journey of making PCB's, it's an AND gate made up of a couple of switches and 2 transistors, some resistors and and LED. I have a CR2032 battery holder to provide power.
When i first started I had the battery holder on top which is SMD and it just has pads to solder to, the rest of the components are through hole, but at some point I realized the pads for the through hole components should probably be on the bottom. So rather than routing stuff on top I moved the battery holder to the bottom and figured I would just do all the routing on the bottom, with the silk screen layer on top. For some reason when i do this the auto-router just gets confused and never routes the project, so I am thinking I have something wrong.
The pads for the through hole components seem to be set for multilayer and I set all the rats nests to be on the bottom layer so i thought stuff would just automagically work. =)
I made the project public if someone has time to look (if needed)

Appreciate any help. =)
