The Arduino GRANDE is a fully functional Arduino that is about six times larger than real life. These are the laser cutter plans for making a comically large, functioning Arduino for demonstration, comedy, and educational purposes. I built the GRANDE for 2012 Bay Area Maker Faire. http://jedgarpark.wordpress.com/2012/05/15/arduino-grande-2/

<ol>Cut the parts from acrylic (5mm and 6mm depending on part, see color coding in files) and etch the graphics. Paint the graphics with acrylic craft paint and a squeegee for added contrast and pizzaz! Use 1/8" banana plugs as the headers. Use a doorbell button for reset. Use panel mount LEDs for the SMD LEDs. (NOTE: add a 10K resistor to the power LED, the pin 13 one doesn't need it.) Use a panel mount USB B female-to-male connector for data transmission. Use 4-40 screws and nuts to assemble. Wire a real Arduino to the headers, reset button, and LEDs. Place rubber feet underneath. The rounded power jack top is made from a painted cardboard half tube. Hoist it on your shoulder like a boom box. </ol> Now, you're ready to wire up all sorts of Arduino peripherals (LEDs, buttons, knobs, speakers, etc.) with 1/8" banana plugs and make your demos bigger than ever. NOTE: I removed the Arduino and Atmel logos from the file, feel free to add your own.
