Just got it a few minutes ago. I thought it was going to come with an SD card, but I guess not. Not a big deal. I have a ton of them laying around. Now I'll have to go find the files to see what it does when it boots up.
Well, I did take a few minutes and set up an SD card, found a keyboard and mouse. It boots up into Linux. Took a bit of reading the forums on raspberrypi.org. I'm NOT a Linux guy at all.
Was able to get the GUI started and it seems to work. I do notice that my TV does not really like the signal. It seems mostly stable, but the screen flickers every 10-15 seconds and sometimes the TV says the signal is out of spec. I'm using a newer TV with HDMI inputs and the TV is 1080P.
I think for the $40 I have invested, it's worth it. Will be a while before I get a chance to push it much and see what programming I can do.
Well welcome to Linux.
You may find that reading some of the original Unix documentation will be far more helpful with low level stuff than trying to Google for modern answers.
Unix/Linux is is very much about two separate streams of data - character (traditionally 8-bit or multiples thereof) and blocks (originally 512 bytes per).
These days, most of the systems utilities have been combined into an application called Busybox. The utilities are quite important for building small applications and interfaces. Also, learning the shell programs - usually called BASH is very helpful.
The feature that seems to be the most unusual for the Raspberry Pi is the the whole video generation side of the unit. Learning Linux's XWindows does demand a real commitment to understanding Linux as a whole.
Linux has quite a bit that is configured in text files. Some text files are clearly noted as NOT intended for editing. Others may not be as clear. The usual approach is to make a backup before you try to modify. Some of the traditional Unix/Linux text editors do this for you.
After a wait of a few months, I was invited a week ago to place my order for a RasPi. I thought about it and thought about it. I looked at all the many boards already collecting dust at Casa de Chaos. I thought about what I'd do that very day if a RasPi magically appeared in the mail.
At long last I made my decision: I ordered a new climbing harness from Black Diamond.
Adafruit has one too that looks pretty cool. I guess the only thing about it is you can't stack anything on top, however there is a slot that allows for a ribbon cable to access the gpio.
That Adafruit enclosure makes the Raspberry Pi complete. One can create a very nice desktop computer by attaching the box to the backside of a monitor. I just may have to get a Raspberry Pi after all.
But here we go again with the "Notify me when in stock".

...or TV. Yep, now you have got the idea.
Note that the Raspi organization is planning to have an enclosure of it's own before this gets anywhere near class rooms or youngsters bedrooms. They want it to be transparent so kids can see "the works" which seems like a great idea.

tick, tock....tick, tock. Yes this is getting to be a drag.
Has anybody noticed that a recent expansion board for the Parallax C3 has become available. It stacks and adds significant video memory for animation and gaming.
I covered sensitive places on the back side of my Hydra with hot glue (others were offended) as bare boards one a cluttered desk do have a high risk of unplanned shorts.
Idon't see much reason to protect the top side, unless one fears the curious will tamper. Still, a complete enclosure makes me feel that I have a complete project to present to others.
Never in a million years would I have thought that more than 5 years later and with more than 11 million RasPi units shipped of more than 6 variant models would we still be waiting for the Propeller 2.
This is not a slight on Parallax, I'm still beavering away with P1 quite happily but my, how time flies! ;-)

With some editing to the text file it should lock in the video.

I suspect that with a little investigation and research, Parallax's C3 will begin to look much easier.
Can I ask if you ended up editing this file, what the original values were, and whet you changed them to.
I guess that you want to end up with something like
hdmi_group=1 (CEA)
and
hdmi_mode=16 1080p 60Hz

I've had an email with my tracking number from RS today so my Pi is on it's way, any sign of your Prop2 yet OBC? :thumb:

PS Baggers has got his already !!

It would be interesting to know how many potential RasPi purchasers follow through......with a new whatever, instead of the RasPi.
I'm on the list....wonder what I'll decide?

It can't be long before you get yours now Jeff....
