Simple prototyping board designed for an Arduino and half breadboard. There is a small parts tray and resistor chart at the bottom. Notches are placed on two sides of the board to attach project pieces. See photo and Arduino Mood Light project for details http://www.thingiverse.com/thing:70372 Design for the base was derived from Nathan's Bamboo Prototyping board - http://www.hahabird.com/2012/09/bamboo-prototyping-board/kiss cut red lines, vector cut black uses three 4/40 nuts and 1/2" machine screws to attach arduino glye the two plates together first
