# electronics design ## eagle ###schematic and pcb layout design my messy schematic ![schematic](http://fab.cba.mit.edu/classes/863.18/Harvard/people/victoria/images/week_04/schematic.png) the board has two LED's and a push button switch as additions to the original design ![board](http://fab.cba.mit.edu/classes/863.18/Harvard/people/victoria/images/week_04/board.png) ##pcb fabrication fresh out of the roland srm-20 ![mill](http://fab.cba.mit.edu/classes/863.18/Harvard/people/victoria/images/week_04/mill.jpg) post stuffing, on the right ![pcbsgreen](http://fab.cba.mit.edu/classes/863.18/Harvard/people/victoria/images/week_04/2pcbgreen.jpg) ## acrylic experiment ###variegated vinyl i cut thin strips of vinyl using a paper cutter and arranged them side by side over a sticky substrate. ![vinyl](http://fab.cba.mit.edu/classes/863.18/Harvard/people/victoria/images/week_04/vinyl.jpg) i then overlaid then burnished copper foil over the variegated area ![copperonvinyl](http://fab.cba.mit.edu/classes/863.18/Harvard/people/victoria/images/week_04/copperonvinyl.jpg) after vinyl cutting my board design, i transferred the traces onto a rectangle of acrylic i milled ![acfront](http://fab.cba.mit.edu/classes/863.18/Harvard/people/victoria/images/week_04/acfront.jpg) ![acback](http://fab.cba.mit.edu/classes/863.18/Harvard/people/victoria/images/week_04/acback.jpg) post stuffing ![2pcb](http://fab.cba.mit.edu/classes/863.18/Harvard/people/victoria/images/week_04/2pcb.jpg) ![2pcboverlap](http://fab.cba.mit.edu/classes/863.18/Harvard/people/victoria/images/week_04/2pcboverlap.jpg) i later added smooth on epoxy finish to the top of the board to ensure the traces don't lift while plugging and unplugging connectors to the header pins ![epoxy](http://fab.cba.mit.edu/classes/863.18/Harvard/people/victoria/images/week_04/epoxy.jpg)
