Not checked in but making some progress with Pingdar - there was a considerable amount of "clean up" form the original WiiDar radar display.

Some things that I noticed - there is alot more range events per single servo move. 

TODO - stop ranging doesnt appear to work. look into moving the servo faster or at different speeds.. try setting an appropriate sample rate.  

Auto-scaling would be a nice feature - to zoom the display out until the furthest rang found is within view.  History of traces options - wether to leave the previous radar sweep data on the field or not .. or let it die slowly..  lots of possiblities
