Raspberry Pi

The Video Tutorial I have been going through has you setup a 256MB Virtual Box session, with Debian 6.0.3 in it… I am not quiet sure, but I think that is so ALL your development is easily moved over to the Raspberry Pi.

Well, it looks like the Raspberry Pi will have quite a bit of Power…

According to the Wiki Page, in the Pre-launch section, “Demos of the board showed it running the LXDE desktop on Debian, Quake 3 at 1080p,[20] and Full HD MPEG-4 video over HDMI.[21]”

So it appears that you can plan on having a Linux Computer, with a 700Mhz ARM 11 Core, with 256Mb of RAM, USB Keyboard and Mouse, Composite or HDMI Output, that runs on 5VDC, and is the Size of a Credit Card… For $35.00 ( USD )

( The Non-Volatile Flash Storage is a SD/MMC/SDIO card of your choice, not Included in the Base Price… )

I just received my Raspberry Pi, on Thr, 28-JUN-2012. See my Initial Photos on Facebook ( Publicly Viewable ).

I took an 2GB Micro SD Card in a SD Card Adapter, loaded debian6-19-04-2012.zip with Win32DiskImager…

Plugged in a USB Keyboard, a HDMI cable to my Second Monitor, Network Cable into the Router, and power from my HTC Phone Charger cable.

I received mine about three weeks ago, have not done much with it yet other than run the recommended linux image. I did find it very fussy about the choice of SD-Card and keyboard, to be honest, I’m not a huge linux fan, I far prefer smaller embedded systems that boot in a few seconds such as the arduino. My favorite that I have used in several commercial projects is from a German company.

and more recently this

Boots in under 5 seconds and runs a full RTOS.

I just got my email a couple of days ago letting me know they were in stock. By the time I got home to order one, they were all backordered :stuck_out_tongue: Cannot wait to get my hands on one of these, I have no idea of what I want to do with it yet but I know I want one :smiley:

I’ve had mine for about three weeks and really haven’t done very much with it either. I have the stock image and it works well. Downside is the only HDMI TV is the main one in the house. So it’s a little hard to get face time on it.

I did buy the Adafruit Pi clear case. I was worried about the bare board being (stepped on, shorted, broken, etc.) Case is well made and supports the connectors. I can also see the lights.

I’ll most likely order the Adafruit Pi Plate expansion and then try some electronics with it.

I’m really trying to decide what I’m going to do with the Pi I have been doing robotics with the PIC, Cortex and Arduino. I’m thinking that the Pi is not going to make it into that group. There are too many hardware interface issues to overcome. There are some articles about running Pi clusters, but that’s going to need to wait for higher availability of the boards.

I also have a Beagle Board that has a lot of possibilities. It has 4 serial ports which makes it a good driver for some of the standalone serial servo / motor boards + serial GPS input. I’m been doing more with Node.js on it. I picked up a small USB Wi-fi card for it, so I don’t need to be tethered to the wire ports on the bench.

One of this biggest downside with all these small ARM setups is the difficulty in getting Java to run. So I’ve been looking at my C roots, Lua and Node.js (javascript) and possibly Processing.js.

I found this article, recently posted at Embedded.com:
“KESO – A Java VM an MCU developer could love”

It needs to run under an RTOS, but this could be a really simply way to get Java Programmers running small Embedded Systems, at least for Prototypes… :wink:

OTOH, I get the feeling that Most Java Programmers don’t know where Java leaves off and the Common Libraries begin, so they might feel that it’s Not Really Java…

I have been following Raspberry Pi for a while now, and I think they would be cool to use. I have never used Linux though, only Windows. Someone should try making a robot with this and see how the bandwidth times are. A Sprint 4G card would be cool to put on it to.
