[K3CAL] Cool technology (not ham radio related)

[KB3WFV]

Hello All 

Below is a link to a video of a new piece of tire mounting equipment that we 
have just installed in our automotive repair shop.

While it is not ham radio related, I thought some of you may find 
it interesting how advancement in technology is everywhere.

The drive motor in this machine is pulse width modulated allowing us to operate 
it at multiple speeds ultimately making things safer and easier for the operator and
for the tires and wheels.

We are a long way away from a couple of pry bars and hammer !
