This is a collection of pictures and videos of devices that placed in the top ten at the 2019 National Tournament at Cornell University. '''Feel free to add more pictures and/or videos of devices. If possible, please include a description about your device.''' Because everyone benefits when we share, devices that did not place in the top ten are sometimes allowed.

The Best of Nationals pages highlight the best devices for building events from recent national tournaments. All photos and videos of devices on these pages are submitted by users.
