my messy schematic

the board has two LED's and a push button switch as additions to the original design

## acrylic experiment
###variegated vinyl
i cut thin strips of vinyl using a paper cutter and arranged them side by side over a sticky substrate.

i then overlaid then burnished copper foil over the variegated area

after vinyl cutting my board design, i transferred the traces onto a rectangle of acrylic i milled

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
