Well, it's been a while since I posted anything...sorry about that...  I've been busy and working off and on (more off than on unfortunately).  So a quick recap of the last 2 months...

I wasn't happy with the way QT looked...and since I've never used it before I also wasn't very happy with the learning curve required just for the software piece.  I have enough of a learning curve with the electronic components piece.  so I wound up ditching QT for Android.  With help from this blog (, I was able to get Android installed on the BBB.

I also build a board that my pumps will plug into.  It connects to a proto board on the BBB and allows the 3V from the BBB GPIO pins to turn on the 12V that the pumps require.  I'll post pics and draw up a schematic at a later point.

I've gotten enough of the software coded to do some testing.

Between the board and the software, I have enough for a functional prototype.  Now I just need to build a chassis.  Below is a quick video demonstrating the Android App turning the motors on and off based on the drink selected.
