SD cards are either rubbish OR work


I have managed to get my 8 gb Sandisk Extreme Pro (class 10) card to boot. It wouldn't work when I last tried - I think the latest firmware updates have sorted out the problems.

I've also managed to get Scratch working on Arch. It's a total hack - I just copied the files from the Debian image. It does work (although no sound atm).

i was thinking about making box for RPi from plastic soap box

something like this one:

I've been playing around with the set-up of my Pi again today.
I'd read about the slow read/write speeds using the sd card slot. I am now just using the boot partition on the card and my file-system is on a usb. I'm not convinced it's made much of a difference tbh.

I've also been having a go with Openbox instead of twm. That seems to work nicely.

seems like a good idea, should be easy to cut holes, I'm hoping to reuse something

this trailer is probably a little too big for RPi Laughing

im interested in making a robot that has camera and mic and recieves its signal via wifi or ethernet (ethernet could be useful when you dont mind a lead dragging behind it and you are in an area where wifi wont give good distance or around corners etc in metal/ concrete buildings or other interference issue sites).

i envision the robot streaming the video to a laptop via wifi and or ethernet AND recording to the sd card at the same time.

i am wanting to create a rasp pi powered robotic probe of some sort.
altho for the wheels/ signal for moving... your prob best off buying a remote controlled car that has big enough wheels and stuff to give good clearance in rougher places like outside on pebbles or gravel type surfaces.

the rasp pi could handle all the video streaming stuff etc.

ive aready bought the remote controlled jeep type thingy in anticipation of recieving my rasp pi in the post. You can get these kind of things for like $50 or so should be suitable. There may also be models that share the same dc voltage as the rasp pi and you could run a line from the onboard battery pack to the rasp pi for the power.

anyone know the voltage tolerance of the rasp pi? will it burn and die if you give it one volt over its recommended, or two volts or 3?

you could hook a voltage regulator IC to the input to keep the input voltage in the sweet zone. It is fairly basic. and has three pins: source voltage pin, regulated voltage out pin and ground pin. I think mine is +- 7 volts in and 5 V out. This is what I used to get a regulated DC out of some rechargeable cells I put into a candy tin.

I've had a go at connecting an LED and a switch to the RPi (following instructions in the MagPi issue 2).
Got the LED to light up, but I think I had the switch in the wrong way.
Will debug later ...

Sub_title: got a raspberry pi, can't wait for puppy
 

Well, the long awaited rpi is here, and I've spent half of father's day trying different distros. (This would normally be a good thing - when asked what I wanted for father's day, I could honestly say, just some peace and quiet and the opportunity to putter with computer hardware and software, and I got it!) But it's turned out to be frustrating. I've tried 3 things, and I don't have any of them in a really good state (although this message is being typed in Debian, so at least that's usable).

This is certainly a device that cries out for puppy linux. I'm a professional computer person who ought to be able to do the google-fiddle-fiddle-fix myself and eventually get there, but I guess I'm spoiled by the puppy world. I've used various puppies on my regular machines, Jemimah's puppeee and fluppy on various netbooks, and they JUST WORK. That's such a relief! I've done linux for a long time, I know that this is more like a beta device and not a consumer appliance, and I know it's early days, still, this is such a pain...

arch: got it to boot to a command line. Is there really no graphical desktop installed? I saw someone's instructions on installing Enlightenment - pages of installation and configuration - and decided to shelve that one.

raspbmc: found excellent (Windows) instructions on how to download and install the installer to an sd card, that all worked fine, and I ended up at the xbmc main screen. Not sure how it works, since I've never tried xbmc on any machine before - but I would be interested in using the pi sometimes as a way to get video or tv off the internet, so this looks promising. However, after a while it locks up with some usb-related errors that I haven't yet looked up on the internet.

debian: I needed to make half a dozen tweaks, but at least they were well documented, I can't get hdmi to work at all after many attempts at modifying /boot/config.txt, so I'm stuck with a max resolution of 678x460 (circa 1985), Also I can't get hexxeh's rpi-update to work, although I have tried all of the workarounds.
