The Arduino and other microcontrollers are designed to ,well, control
things. There are digital and analog inputs and outputs varying from 20
or so on the Uno to 70 or so on the Mega2560. You use a PC (or a Pi) to
write the programs and download them over a USB cable.
There's a Google group using Arduinos for all sorts of model RR
applications. I'm using them to control servos and move turnout points
slowly and realistically at a lot lower cost than the commercial
product. And infinitely more cusomizeable.
Woodworking? A moisture meter would be pretty simple. A liquor cabinet
that weighed each bottle and played "How Dry I Am" when appropriate?
Twinkling LED lights behind the cloth in a speaker enclosure?
One experimenter built a hearing aid using an Arduino. A little large to
fit in the ear, but is sure shows there's not a lot of expensive

Direct TV does that now, in home. Both audio and TV. It has been
do-able over the Net with multi-casting and for the life of me I don't
know why it was kept so limited. One signal that anyone had hook up to
if they know where it's from. saves a lot of bandwidth instead of one
stream to each individual user.
Like you, I have been considering getting one for a while, and the ver

Put an LED bar in the rear window and send text messages to the
drivers behind you. ;)
Haven't you seen signs in the country and back woods - nation wide!
If it isn't the hunters shooting holes in signs to sight in,
it is the drive by fun loving redneck that throws a bottle into
it or shoots it next time.
Just don't ask for bullets or bottles.

That might be a problem. My older RPi B+ (?) uses a USB wiki dongle, which

Hopefully, it comes with a good one.
For example, I passed on the official RPi mini dongle and got the

You should be able to disable the onboard wifi and use a
USB dongle if you want to (which might be something you'd
do if you put it in a metal case, since the onboard wifi
antenna is soldered to the board and can't be moved).
However, one of the weaknesses of the Pi is that a lot of
the low-level hardware stuff is not all that well documented,
so it might take some work to figure out just how to do it.
Oh, I meant the Bluetooth on the Pi 3. Ok, I did a little more looking
and the current knowledge in one forum thread* suggests that Bluetooth
support is there in Raspbian Jessie, but you may need to install a few
things for a GUI interface.
You can safely ignore that statement above ("AFAIK, Bluetooth isn't ready
yet.") and just do some reading if things don't work. (Linux--The OS
that brought reading back to America's youth! lol)
Just citing my source.
Yeah, that's a bit of an apples and oranges comparison; the
Raspberry Pi has more of the architecture of a smart phone,
while the Arduino is the classic embedded controller.
I'm not a great fan of the "true" Arduino, because I'm not a
huge fan of the Atmel AVR processor (altho it's a lot better
than the PIC processor). There are Arduino compatible boards
using various flavors of ARM processors (like the STM32) which
I think are better.
A tiny bit... Unfortunately, Amazon Prime doesn't work with Linux. It
boils down to DRM and lack of interest in making something that works.
MythTV OTOH, runs great on Linux. I wouldn't be surprised to find
there's a "Myth Pi" project.
The Pi doesn't get high marks for audio out of the box. There's a $25
sound board add-on that will give you better audio, but if good sound is
your aim you may want to look at other options.
