Re: Any info on Kuman Sensor kit?

There seem to be lots of bits there. I think what you would wind up doing is examining any part that you want to work with for identifying marks and searching for data sheets and other more specific information. If you just want to explore, this might be a good deal. If you have specific needs for a...

Re: Sd card between Rpi and Windows

As mentioned this will not work as Windows will only recognize the first partition and will ignore all others even if they are FATxx. The first partition is already occupied by the small RPi boot partition. I think I remember some threads on enlarging the boot partition but don't remember if they w...

Re: Sd card between Rpi and Windows

When you say that Samba is not really an option, do you mean that the Pis and the Windows PC are not networked? Are you looking for a solution that involves shutting down the Pi and moving the SD card to a PC to copy the files? With networking, I would go with something like unison which has a Windo...

Re: Pi as an Sd-card reader/writer

Re: Pi as an Sd-card reader/writer

Hi Tom, I'm not sure what your ultimate goal is. The typical configuration is to run the PI on Linux which is a disk based OS and use the SD card as the disk. An alternate approach is to boot from SD (which is required) but have the root (e.g. main file system, equivalent to C:\ on Win/DOS) on a USB...

Re: Rasbian Lite - Install and configure with LXDE

One thing to consider when going to a smaller card is that it will usually be slower. I have done some benchmarks on various cards and for some (Silicon Power 32 vs. 64 GB) the difference is astounding. If your target app depends on 'disk' speed this may matter. For me, this only matters for interac...
