Project Dyson - I test fitted the electronics and everything seems to work/fit correctly.  The arduino pro mini fits nicely in to the handle with all the wires squished in. The ESC + voltage/current sensor will be fit into the hollowed out battery housing. I will use velcro straps to attach the LiPO battery to the bottom of the original battery housing.  

Depending on the size of the screen once I get it, I may need to move the potentiometer down a little and center the screen on the rear.  

I also have an airspeed sensor from 3DRobotics on the way. I will be mounting that in the motor cavity to detect when airflow drops (when it shouldn’t) to detect possible blockages, and drop motor RPM automatically.  I think ill try to write some auto un-block routines to try and automatically unblock the vacuum.
