I ran across this in a blog I happened upon and it kind of stunned me. At first I thought it was a joke but then I got to thinking it has more power that we sent to the Moon in Apollo 11.

This is what got me laughing.

My son bought one but I cannot convince him to run BOINC on it.

Reminds me of the old TI99/4A that I had. Both of my older kids learned their colors, numbers and, shapes on that old thing. I wrote a little routine that looked like a slot machine with the Lucky Charms shapes and then added points. They got points for 3 of a kind and a bonus point if they could correctly add old score and new total if they won and another if they could enter the correct shape name. It was hooked up to and cassette tape deck and the TV.had 4K of RAM. They would set and plat that stupid thing for hours. Of course the only other video game at the time was Pong.

http://learn.adafruit.com/adafruit-ultimate-gps-on-the-raspberry-pi/

use-cases:
recording and streaming positional and time-series telemetry
tracking objects in motion (eg your new RC quad-copter)
constant velocity controller
independent way-point navigation for your robotic vehicle / boat
telescope controller
dog-cam w/ locator
shark-cam w/ locator

...are some that I can think of

these R-Pi parts may prompt you to come up with more ideas: http://www.adafruit.com/category/105

ZoneMinder has the goods for Linux:
http://www.zoneminder.com/documentation#featureList

I use Yawcam on windows:
http://www.yawcam.com/

The idea is that you can make yourself a portable motion detection device (handy for camping etc) with a USB stick, USB Cam and rechargeable battery.
You could also use it for time-lapse photography if the resolution of the USB Cam is up to it.

What I am particularly interested in is the Yawcam feature that can alert you (audio + email) when motion STOPS rather than just when it is detected.
There are lots of use cases for that feature.

More ideas flooding into mind as I think about it ...

Raspberry Pi Cluster
http://blog.afkham.org/2013/01/raspberry-pi-control-center.html

"Once the cluster was up & running, we ran a series of JMeter load tests. Preliminary testing was conducted using an 8 Pi cluster. At a concurrency level of 750, the cluster was able to sustain a throughput of 350 TPS at an average latency of close to 1 second. We are working on improving these figures." (Afkham Azeez)

Dave here is another quote from the article that you posted;

"we decided that we had to be able to optimize our middleware to be able to run on resource constrained environments. The Raspberry Pi model B has only 512MB of RAM & a 700 MHz ARM processor."

In some ways it seems that IT is going backward. I got out of IT because I felt that being a programmer was just becoming a PITA and your could train a monkey to do it since the new way of doing things was to throw more processor speed and RAM at inefficient code. And it seemed that I spent all my time fixing code that some kid threw together. Of course I was also sick of the salesmen out selling systems that we hadn't written and then coming to us and telling us when it was expected. We were some of the first to do online realtime processing at McDonnell Douglas Automation, that was in the mid '70's, but that was on a 370/160 with 10MB of RAM. I started on an IBM 360/30 running DOS and the code you wrote had to be efficient. The thing was S....l.....o.......w. I look at this thing that is the size of a cigarette pack and am amazed. That 360/30 only had 256k and when we made the jump to 512k the extra 256k came in on a semi trailer lowboy flatbed. It was huge and required the removal of a section of wall and a ramp built to support the forklift to put it in place. Now I see people talking about having to "optimize code" I just can't help myself I just crack up. I would love to see one of them sit down and write something in IBM Assembler, that would be a hoot.

This looks like it would be a gas to play with. However when I went online to see about getting one, it appeared that there were only a couple places selling it and they were back ordered. Plus there were many complaints about how long it took to get them, etc. So I didn't order one from them. Too bad they aren't at NewEgg or something like that. :-(

02-22-2013, 03:20 AM
I was able to get one from: http://www.mcmelectronics.com/content/en-US/raspberry-pi I haven't really played with it all that much yet, but it looks like it could do some interesting things when a guy gets some time to tinker. I was lucky and hit a free shipping deal as well around black friday.

Hey Jason, thank you very much!!! Just got off the phone with them and have one on the way now so I will soon be able to start playing with the thing! Looking forward to it. Lol

Another linux toy to play with <big cheezy grin> :-)

your welcome. I'm interested to see what kind of uses you find for it. I had in mind a kitchen computer for online recipes and shopping lists after i get some tinker time. I am looking to try a few more linux flavors on it before i decide what i like. It may also be fun to experiment with a few of the addon boards.

Brucifer
02-24-2013, 04:03 PM
For starters I'm just gonna play with it to see what it's like, hook it up to the net, etc., and like you get some other flavors of linux running on it besides the Wheezy. I'm sure that as some time goes by that the brain will start thinking of other things to do, and that the original one will end up with a few more for company! Lol

As they're made in the UK, the UK stock seems to be pretty decent now (it's one year today since they launched).

Mine's being boring and being currently used a NAS (with attached 3TB external) and general mini home server. It's also crunching on Dnet - RC72 seems to be about 650,000 Keys/s in comparison to my Xeon which seems to be doing about 7,500,000 keys/s - which seems low for the CPU as I've currently got an Intel Atom VPS running the client and that seems to be doing about 8,300,000 keys/s (Atom N2800 @1.82GHz Vs Intel Xeon W3503 @2.4GHz :sad5: )!!

Looking to get a few more SD cards for it so I can plug and play different operating systems while keeping the main one without breaking it! Currently running Raspbian (installed from the installer, not the image file) to minimise crud.

Looking to see if it'll run an OpenTTD server successfully but I need to compile the code - I'll be getting a different SD card to give that a go.

Well I'd like to join in the fun, but I'm still waiting for the brown santa to bring mine to the house. :-) Definitely anxious to play with it though!!

Extra advantage is that it is open to people outside the USofA

And while we're at it, ever heard of Arduino (http://www.arduino.cc/) ?

Installed BOINC on mine tonight.



Sun 7 Apr 20:11:18 2013 | | 239 floating point MIPS (Whetstone) per CPU
Sun 7 Apr 20:11:18 2013 | | 960 integer MIPS (Dhrystone) per CPU



:icon_lol:

Running Enigma@home - currently downloaded two tasks (here (http://www.enigmaathome.net/result.php?resultid=42111677) and here (http://www.enigmaathome.net/result.php?resultid=42112036)). Initial estimate was 11 hours a unit :/

We'll see how that goes - at that rate, might drop it back on Dnet, as at least that's a unit every 3 hours!

I currently have mine on asteroids@home with the first unit completing in 3 days 51 minutes at stock speed. If it uses around 4 watts that work unit was about 3.5 cents of electricity. Would that be hard to beat with a typical PC?

Well I'd need about 5 to match the integer speed of my Mac mini, which draws 85W at load (according to Apple, not sure on actual).

So that's maybe 20W for perhaps similar performance (if the floating point speed meant it produced the same amount of work). Downside, ARM, so it's restricted on various projects.

Overclocked the Pi using the inbuilt config file. Upped to 950MHz (High), rather than Turbo to avoid any SD card corruption that the Turbo mode could potentially add.

Benchmark for RC5 on Dnet went from 770,000 keys/s to 1 Mkey/s. Not to shabby.
Might move to BOINC at some point - what's the projects that are supported? Asteroids and Enigma? Trouble is with Enigma, it no longer has my results that it returned (no credit there either!) so I'm loathe to run that on it again.

Seem to be spamming this thread a bit...

Just ordered myself one of these (http://www.element14.com/community/community/knode/dev_platforms_kits/element14_dev_kits/next-gen_beaglebone).
I like playing with low power computers (used to mess with the VIA chips) but these are cheaper and more fun to play with (need some Lego to make a case for this one :P)

Already set your sights on a Parallella (http://www.adapteva.com/products/eval-kits/parallella/)? Seems to be out now! People are experimenting (http://www.parallella.org/) with it.
Look for Lego at the local Oxfam or likewise charity shops....

Out of interest, you might remember my benchmarking thread here (http://www.amdusers.com/forum/showthread.php?8965-Benchmarking-Help). Well, I got the Raspberry Pi crunching it... (v6 which is slower...)

My Xeon crunches through the benchmark case in 401 seconds. The Pi takes 26,560 seconds....:icon_lol: (I doubt it was helped by the RAM difference either - the Pi has 512MB and the Xeon has 32GB...)
