[ELECTRON] PHP - question. . . webcam script...again(ish)

[Ben Dembroski]

Hi all,

Thought I should chime in here.

There are two power supplies at the beacon.  (I'll write up more about 
this later).

There is a 12v lead acid battery that is powering the phone and the 
arduino via a car cigarette -> USB adapter.  The other is an array of a 
bunch of AA's powering the beacon.

Clearly, this isn't the most efficient setup with a bunch of the power 
being lost to heat through the volatage conversions and whatnot.  
However, the system is robust (so it seems) and the batteries were 
cheep.   I suppose it's also worth mentioning that battery isn't really 
an issue.  The python script crashing is the real reason we've been out 
doing service calls...  We've just been changing batteries out since we 
were out there anyway...
