Re: When you've sold 10000 rasp pi, and are waiting for the next order....

I agree with the original poster. Going to landscape mode helps, but still lines are truncated and some words missing. I need my hourly R-Pi fix, so please fix (althought fixing it after sending out the first 10k is ok with me

Re: Gertboard

<t>Never touched an Arduino myself, mostly because it wasn't around when I started playing with AVR. Most of the stuff I want to interface with requires 5V though (Mag card reader and servos etc), so I will probably need to mod the board for 5V operation, unless the buffers are running 5V on the "ou...

do you have any dimentions for the gertboard with headers?


I count ~50x2.54mm width and ~35x2.54mm height

Re: Gertboard

<t>I took a look at the schematics and realized what you were doing. I like it! Kind of like a breadboard but without all the loose connections.<br/> <br/> AVR are pretty nice to work with and will love 3V3 on the inputs, even if CPU is running on 5V. A 1k-10k resistor in series with the avr output ...

Re: Gertboard

<r>Another design wish:<br/> <br/> It is possible brick a 328P by setting the fuse bits wrong, particularly those involving clock source (after all, the first thing you do with an AVR is to either to zero the clock prescaler fuse-bit or change to an external clock source).<br/> <br/> It is however p...

Re: SplashTop OS?

<t>Considering the "BIOS" takes about 2 seconds on a beagleboard and probably sub-second on R-Pi, it would probably be more correct to ask how quickly the OS can be up and running. I know puppy can boot pretty quick, but I'd wager noone knows exactly how quick (yet). From kernel load to init it seem...

Re: Gertboard

<t>Another vote for AVR.<br/> Connecting the reset and the SPI lines to the RPi it wouldn't require any extra equipment but a soldiering iron($10-$20) and some solder(could be included in the package?) to get it working. Ie, no programmers, no magic code pre-flashed on the processor etc. The bigger ...

Re: CAN Interface

I'm a complete newb when it comes to both PIC or CAN, but I know Atmel have some chips made for the can bus and they have good dev environments, documentation that even hobbyists can understand and lots of examples. Maybe something like that could be added?

Re: Which language would you choose to teach programming on the RPi?

<t>Personally, I would probably use Perl. Perl is easy to begin with (no magic starting-methods except for the hash-bang at the top) and you can really tell what each datatype you expect back just by looking at the prefix. You don't have to tear your hair because you pressed tab instead of space and...
