Electronics Design Assignment Week of March 5, 2014: This week's assignment is to: add a button and LED to the echo hello-world board, check the design rules, and make it.	1. First step was to download Eagle.
2. Next, download the Hello Echo Board schematic.	3. Then the Hello Echo Board layout
4. Download and install the component libraries - check! Oops. I created a schematic using the incorrect library and it took hours to fathom out how to install the correct 01 libraries. Thank you to Jonathan and Tim for their help with this. This is the schematic I created with the incorrect library. This is the schematic I created with the correct library.	5. Then I used Eagle to edit the board - unfortunately, the spaces between traces are too tight and there is a wire from a node that needs deleting. I will start the process over again. Onward. 6. April 23 - I designed....
... and milled a new board.	7. May 4 - I stuffed the board at the Haystack Fab Lab weekend workshop. Mickie Flores Home
