Arduino microcontrollers are small enough that we’ve seen them used in everything from milk jugs to microwaves, but John Edgar Park wanted something bigger: so he’s built the Arduino Grande. Park — who writes for Make magazine and works at DisneyToon Studios — will not only be showing off the massive microcontroller at the upcoming Bay Area edition of Maker Faire, but he’ll also be running a presentation on how to build one yourself. The device is approximately six times the size of a standard Arduino and is fully functional, and it was built using 3D modelling software and a laser cutter. We’re not quite sure what you’d use such a huge microcontroller for, but if you’re in the area you can check out the presentation this Saturday — it even includes a live laser-cutting demo.
