I've added a new product to the PSG stock: a USB to mini-USB cable. This is the cable required by the standalone sentry controller.
In addition, we are working on a few large changes for the next code release. Among these is a long-awaited game controller / joystick input option. During manual mode, the user will have the option of using a USB game controller, such as a PS3 or xBox controller, or a USB joystick, to aim and fire the sentry. The user also has the option of designating other functions to buttons on the game controller / joystick, such as toggling manual/autonomous mode, setting the background, etc.
Less exciting but still relevant, all customizable settings will now be saved to a .txt file when the code is closed. This means that users will no longer lose their custom settings each time they run the code or change code versions. Previously, the only way to do this was to save the settings to an Arduino or controller.
Finally, we are tweaking the startup settings for connecting to to the Arduino/controller, as well as giving the user more control over these settings in the control panel.
