Challenge for Ben: Arduino based smartphone

Seems pretty legit, however the new Galileo arduino should be used so you can get a little bit of processing power, as standard arduinos are using low power arm based microprocessors

maybe a Feature phone but i think a "smart phone" may be pushing it

I think full size arduino is not so good for a smartphone. May be arduino pro mini?

And I would prefer building the device in cyberpunk style, it would be a great alternative to the iPhone

i really think you guys are missing the point.  the ATmega328 has a clock speed of 16 MHz, most feature phones have more power than that it's just not the kind of thing that would work well

You may be able to get away using the Raspberry pi but even that is low power by today's phone standards.  the average phone is 1.5 GHz dual core and the Pi is 700 MHz BUT running an old version of android it would be fine.  the real problem is making it read sim cards correctly!

wow okay the 700mhz is not a lot granted..but average phones have 1.5ghz...are you out of your mind the iphone was just about over 500ghz last time i checked and the Samsung galaxy s3 1ghz Sony experia only 1ghz htc 1 1ghz....

apple and Samsung haven't made single core phones for over 2 years!!! so you may be able to load android 1.6 on it and have it be stable.  even my 5 year old sony hs a 1gz processor and lags on 2.0

the SGS3 is a 1.4ghz dual core and is a year and a half old

the SGS4 is a 1.6ghz quad core

the HTC 1x is 1.5GHz quad core

the iphone 5 is 1.3ghz dual core and is over a year old (the 5s is the same)

the sony xperia Z is 1.5ghz quad core

and the big 2

SG note 2 1.6ghz quad core

SG note 3 2.3ghz Quad core

now if you ignore the notes you get an average of 1.46 ghz and the average amount of cores is 3.2 cores

you also need to keep in mind that all of these phones have large Graphics processors to

NOW.... this is not to say that the RBP can't do it infarct it could but by today standards it wouldn't be considered a smart phone as it would have to run a very old version of android!  it would feel like an iphone 3g or an ipad 1, neet but very little use .

HOWEVER i love the idea of building it just to build it but due to the lack of sim dialing compatibility i would make something like a 7" tablet it would be cool cause oyu could also dual boot it with a desktop os like raspbian

I know about high frequency (I have HTC HD7 with 1ghz cpu). of course, cellular module is not a part of arduino. Arduino only control it.  If do not need to play modern games, frequency it's not a problem!

Arduino cellphone

Make cell phone calls with your Arduino

Here are some examples to get an idea of what something like that would look like/operate like.

like i said i'd be fun to build but impractical also now we are talking about an arduino + sheild + pi +display + power this is gonna be big (about 1/2 the size of the pi portable)
