I have started using my I pad most of the time.
My normal Internet
connection is via 3G dongle, so replacing this with a MIFi means I can Internet
to the non USB equipped iPad
However I occasionally use some of the free Internet connections available via a booster aerial. The Alfa AWUS036H booster also needs a USB connection but alfa sell a modem
called the R36 that will re-broadcast the Alfa Internet connection so weak signal can be used by iPads ( and PC at the same time if you want)
This is the basis of the commercial
Wirie ap.( but this homemade version is much cheaper)
I made the addition of adding a sealed lead acid battery
. This increases the bulk, but means no wires are needed at all. It sits nicely on top of my boom where it is above all the structures apart from the mast
, but is not waving around much (important with the higher gin antennae).
The power requirements of the booster and modem
are small so the unit will function for 5 hours before the batteries are at 50% . The batteries were only $35 so if discharging more a short life is not a big deal.
