Crash course in Eagle CAD: video demo of schematic to layout

[culturejam]

One more thing to check on your layout: the trace running next to pin 1 seems too close. One thing I omitted from the video is setting up Design Rules and then using the DRC (Design Rule Check) to make sure you haven't broken any of those rules.

Also, run ratsnest (type "rat" and hit enter) to fill out the pours. I see you have the 9V pad routed to the IC. If you have the top pour merged with the 9V net, this connection would happen automatically. Same for connections to GND.

So go back and add those connections (dots) and then update the layout with the RAT command see where things stand.


I use Dorkbot for prototyping.

There we go:

Now,  you want to rip up the traces from vol 1 running to the diodes and pin 2 of the IC and then run RAT again. And I think pin 4 isn't properly connected on your schematic. If it were, it would have automatically connected to the ground pour on the bottom layer.

You're almost there!

Positive leg of C1 is not connected to anything, is it?

And the diodes are in line with the signal chain between IC1 and VOL, not going to ground.
