Re: using 4 AA batteries to power the Pi

So will the R-Pi run with 4.8v?
I want to make a simple UPS and this will help a lot because even the most efficient voltage regulators will drain my NiMh rechargeable batteries.

Re: micro sd adaptors

About the MicroSD adaptor, they are just a dumb piece of plastic. The pins go straight forward to the ones of the SD.

Re: Why not MicroSD?

Some years ago, when MicroSD cards were really expensive, a friend of mine was installing one in his new phone. To open the case of the phone he needed both hands so he put the card between his teeth. Too bad the card broke in half

Re: Official image and QEMU?

TIP: If you want to mount the FAT32 partition from the image use something like this:


sudo mount -o loop,offset=1048576 -t vfat debian6-17-02-2012.img /mnt



Useful if you want the kernel from that image.

Re: Ext4 or Fat32 for hard drive?

I have noticed huge CPU loads when writing to NTFS in Linux and many other problems.

I would stick with ext3 or ext4.

(there are drivers for Windows to add ext3 support if you want to be able to read the partition from Windows)

Re: Viruses on the RasPi

The risk of getting infected on a Linux machine is so small that you don't need to run antivirus software. Run Linux on ARM and you make the probability even smaller.
