Skip to comments.Freeping on a 35 dollar Linux computer :-)
Posted on 06/24/2012 12:53:15 PM PDT by Bobalu
Just got my 35 dollar Raspberry Pi Debian Linux computer and thought I'd show fellow freepers how to get on the web and freep on the cheap. It's a Linux setup so it's pretty secure compared to Windows. I'm installing a web server on it now (Apache) and trying to get a cheap USB wifi dongle to work so I can disconnect the ethernet cable...the less cables the better!
Thanks! I and a few other FReepers will love this!
I’ve been following the progress with the Raspberry Pi project for some time now. A wonderful idea. Looks like the perfect web browser - media server solution.
Question: is there any progress on the packaging front? When will I be able to buy a full packaged RP?
You might want to get your money back. Every time I click on your post I get a “Service Temporarily Unavailable” message.
Yes, the first page I tried to bring up on the PI was FR and I got that error message! I thought at first it was the PI but FR is acting flakey today for some reason.
I’m far from an expert on The Pi having only been using it for about an hour here. There is a lot of info on the web though so just do a quick google.
Adafruit has a really nice clear case for the Pi, her stuff is always worth the money! You can see the 15 dollar case at this link. (I ordered one myself but it’s on backorder)
What are you using for input? Are you using a usb hub? I can’t access YouTube easily because I’m on my Edgejr tablet at the moment.
Got a link to a specs page?
I got distracted by the Barbara Eden videos you posted.
Don't forget to initialize the registers...
Watching your youtube video I believe something is wrong with it. I don’t see a 503 error displayed.
Great. Now we know who is causing all the 503s today.
I have a 7-port USB powered hub plugged in. Then there is a USB keyboard, USB mouse and a half watt Alfa USB wifi dongle...all plugged into the hub.
Please post the link, I can’t find the BE vids!
Yep, 3 clips. Two from an old TV movie called “The Woman Hunter” (I’m pretty much the only person with an HD copy)
And the one with her and Phil Spector.
Oh, and 1 more, a clip from “The Brass Bottle”
This is the film that led to the “I Dream Of Jeannie”
Hmmm.. I am using on one machine a $3 bluetooth dongle that works pretty ok with my old ubuntu. Wonder if it will work with the RP. Less cables makes me happy.
Tonight at work I am experimenting with a $5 Windows wifi dongle. Our ISP goes down often however we have another relible wifi source and neighboring companies with geeks like me have cleared me to log on with them in emergencies.
An RP Linux setup would be perfect as a backup. I can keep it in my locker and pull it out when needed.
Got a question for you since you like puzzles. My Toshiba laptop developed a crack in the plug where the hard drive plugs into the motherboard. I cannot get the plug up to make consistent contact now so the laptop is useless ... unless there is a way to replace the slot in the motherboard where the hard drive slips in. Any ideas, or do I have to find a new motherboard which will work with the hard drive and figure out how to disassemble the whole laptop without destroying the grounding, etc?
I hate to be tied to the computer to listen and I also hate running the big PC just to stream audio.
The Pi uses 3 watts according to my kill-o-watt wattmeter.
I have the audio out on the Pi set to HDMI, a second sound card would be nice.
I usually manage to cobble up a repair when faced with such things. But I have good equipment to work with here, hot air rework gear, USB microscopes..etc. Cracks in a multi-layer board can be very tricky or impossible to fix.
I’m impressed. The closest I can claim was running Ubuntu in live mode on my old $30 Dell D810.
The youtube page has been favorited too.
Reading about things is nice but seeing in action is usually a big step up.
The slot to plug into had a piece break off on one surface where the HD slides in. I’m wondering if I could solder onto the contacts a new connector allowing me to plug in a hard drive to the connector. I can alter the case to accomodate the little extra space needed for the plug and wire to attach the HD and close the cover. How delicate is the soldering to attach contacts to bare wire of a plug cable?
Dittos to that! I finally pulled my Chinese IP webcam because the neighbors were getting worried the landlord might see something they don’t like.
Really that is not a problem.
But the big problem for me was setting it up. The manual in Chinglish, using a server in HK , and the Comcastic IP was a real Pain.
Best info was found on YouTube.
Sounds do-able to me.
If you are not experienced at soldering then check out some youtube how to solder videos.
I’m guessing it’s a SATA drive? It would have been no fun at all soldering up a new connection cable to the old HD interfaces...lots of pins.
Usually there is a good how to video on Youtube for all kinds of things.
A few of them have been a big help here and there because invaribly something was lacking in the directions sometimes or the directions would be poorly written.
One channel out there involved about working/upping the new droid phone helped a ton.
Yuo SATA drive. I have it in an external case right now, moving files to my desktop so I don’t lose them.
You and your “cat & mouse” games!
my husband and son built a linux computer as well I used it for a very long time. dirt cheap too.
thanks for the ping, this is worth following
The closest thing I can find to your problem is a page about fixing a damaged SATA slot on a COMPAQ laptop, but it might give you some ideas:
This site has info on how to disassemble Toshiba laptops:
Thank you very much! I shall pour myself into them straight away.
The laptop in my office has no hard drive. I PXE boot off a server in the other room. Of course, it’s not very portable, but a laptop w/o a harddrive is not useless.
I was wondering if it might be possible to create a P2P backup for FR based on a bunch of these little Pi’s. With some custom software running on them all you would need is a 35.00 Pi plugged into the cable modem/DSL modem of several freepers. Power use is 3 watts or so and an old cell phone charger provides the power. Storage is on a cheap SD card.
Newegg has been selling 32GB SD cards for 18 dollars including shipping. 4GB is enough and those are pretty much throw-away items now.
A network of these things could ensure a P2P system would never go down. I’m an embedded systems guy, wish I knew enough about this type of software to create it myself. Don’t have the time to start from scratch.
Very nice. I am a huge Linux fan and have been following, with curiosity, the RP. Thanks for posting!
If you can get a Eucalyptus cloud set up with those things, then it should be doable without custom coding, since the cloud creates an instance that functions as a single machine. So, you should be able to just set up that instance like a single Linux server. The tricky part would be adding that cloud to JR’s load balancing set up.
Although I’ve been lured in by the appeal of crazy-inexpensive tech before, usually I end up being frustrated when I start bumping up against the upper limits of the tech’s capabilities.
Actually, looking into it a bit more, Eucalyptus might be too memory-intensive for these things. But, it looks like someone has already figured out how to setup up MySql Cluster on the things, so that might be a step in the right direction:
A commenter there also tells how to increase the available RAM by unallocating the memory to the video chip.
You have to be realistic about cheap gear of course.
This is a 700mhz ARM11 with a graphics processor along side.
You need a good SD card (Sandisk is good). Don’t try to run too many programs at once... just 700mhz so it can’t handle what a quad core 3.5ghz machine can.
I tried playing some HD videos, some played better than others...some would freeze for a second now and then. I probably have something configured wrong. (XBMC) It’s amazing that something this cheap can play HD at all.
It has 2 rows of gpio pins on the board. I will try controlling those and see if I can make an LED blink :-)
I program ARM so perhaps I can get something going.
I took the Pi over to the workbench and hooked it to the 42” Vizio that I use as a computer monitor there. (This is where I usually do my freepin) I connected a 1TB USB HD and started playing a 720p mkv file that I made from a blu ray of “2001 A Space Odyssey” results were very nice. See the short video I just posted. For some reason I could not get the captioning to stop....I may actually have to rtfm.
Congrats on the Pi. I will have to get one to play with. I’ve written code under Linux on my TomTom GPS, and I bet the Pi is similar (both ARM).
I program ARM, AVR and other controllers with GCC.
It’s too bad the Pi does not have VGA output.
I could probably get VGA out of the gpio pins but it would be rudimentary like what can be done with a uC as a hack. There is talk of a cheap official add-on to get quality VGA graphics.
Out of the box the Pi can do HDMI and PAL/NTSC
HDMI is the most important video output any system can have right now. VGA is dying off fast. Be nice to use all those free for the asking old VGA monitors on the Pi though.
what is that?
