Re: Larger boot partition wanted

Thanks for all the points, guys. And especially to jojopi , who hit the nail on the head. Using Debian on a PC at work I was able to add a replacement boot partition at the end of my SD card, get it to show up as a 1.3 GB partition on Windows 7 and boot from it on a Pi. I can now use the same techni...

I've already got one - the boot partition - and it's not big enough. I use the Pi as a data logger and I need to collect logged data in the field with minimum hassle and no network.

How long is a piece of string?

Does anybody have a rough and ready answer to what's the maximum length of an i2c bus?
I guess it could be extended by adding buffers, but after how much wire (assume Cat 5 cable or similar)?

Help needed with Hygrochip HYT271

Does anybody have any experience of using one of these humidity sensors with an RPi? I'm happy enough with the number-crunching bits, but am a bit lost with the i2c end of things. If anybody has some Python routines for communicating with this sensor or something similar, I'd be glad of some pointer...
