Sometimes you just can't route it single sided and need jumpers. Upload the .sch and .brd files and I'll see how far I can get with it.

How do you plan to control each LEDs output? In eagle you have to use nets not wires.

You can see the airwires in his screen cap, he's netted everything, he just need to route it all.

Taking a look at it quickly, do you mind of the 'red wire' leds are turned around?  You might be able to route everything if they are turned around 180.  You just have to remember when placing the components that those LED's are backwards.

I gave it a go, and barely got it on a single side.

You'll want to clean it up or redo it, but it's possible. ;)

Have it autorouted and it might give you a hint on the routing, Just a suggestion.

That was really well done Tyblu.

I think it would be easier if the odd LED was turned around 180 degrees, but since the OP hasn't come back to this thread I'm not going to give it a try.

Could someone provide me with a link for downloading MCP73871.lbr (QFN20) and BQ24210.lbr (WSON10)?
I could not find it on the internet, and i can't make those footprints in Eagle because i suck at software and i hate software.

EDIT: I have found MCP73871.
