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/
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.
