• In Video 2 - The tutorial asks you to auto-route your traces. Please do NOT auto-route your traces and instead manually make the traces yourself.
• In Video 3 - The tutorial asks you to export your parts lists. You do NOT have to export your parts lists, but you do need to generate the Gerber Files for the board.

1. Install Eagle and necessary libraries.
2. Follow and participate in all three video tutorials.
3. Email Mentor/Leadership Team with your completed files with subject line “[SCEL] Soared like an EAGLE” (Don't forget to cc “[email protected]” in all your SCEL-related emails!).
