While there are a couple of open-source brushless drivers already available, [neuromancer2701] created his own brushless motor controller on an Arduino shield.

The Arduino has been used for many purposes, and “shields” are available to make many common tasks easier. However, [Nick] wanted a stackable motor driver shield, so he build one himself!.

The 1Sheeld, a single shield that lets you replace all of those other shields with your smartphone. Today, that project went up on Kickstarter and almost immediately destroyed its fundraising goal.
