This open source sentry gun controller board builds on a great concept by getting rid of the Arduino board. The previous version was an Arduino shield, but this upgrade keeps all of the cool features by rolling the necessary parts into one smaller footprint.
The image above doesn’t quite convey the scope of the project. Go take a look at the feature from last year which used the shield version of the controller. That build used a servo-mounted paintball gun in conjunction with a webcam. You can still build the same platform, but use the open-source files to include this board. It has outputs for three servo motors, and can also interface with airsoft or paintball guns which have their own electronic triggers and integrated batteries.
We always like to see the schematic for projects like this one. For your convenience we exported an image from the Eagle package. You can find it, along with the demo video, after the break.
