Re: STICKY: HOWTO: Move the filesystem to a USB stick/Drive

HI to all, I did follow procedure in first page. I have a PI1 and last Raspbian stretch (april 2018). I did notice that last /fstab is a bit different, by the way I did follow the entry for /dev/disk-by-uuid Of course, I did change also the cmdline.txt. After the reboot, PI hangs with emergency mode...

Create new user same privileges of pi user

Hi to all, I would create a new user (let's say raspberry), that has same privileges, skill, groups, sudo without password, etc etc etc as default pi, and remove pi. I'm asking because I would use a couple of software that they "use" an user with same priviliges of pi. Another example, imagine that ...

Re: HOWTO: Move the filesystem to a USB stick/Drive

I will try with the 2... or someone know that for sure it doesn't function?

Edit: I did try with the PI2. All instructions goes well, but PI doesn't restart. Sigh.

Re: PI don't want reconnect to wifi when I drop it (for test

I did not tested. Because I would that if wifi goes down (e.g. for a power drop in the house) PI automatically reconnect, when I'm outside of house.

I will test with another wlan and / or with another router. I'll tell you.

Thank you for the moment for your time!

Re: PI don't want reconnect to wifi when I drop it (for test

Nothing.
Tested with your allow hotplug and it won't reconnect.

Tested adding the "auto wlan0" in interfaces and won't reconnect.

When I type ifup wlan0 I see the led on the USB wlan goes on, but it won't reconnect. The only one thing is reboot the PI....

PI don't want reconnect to wifi when I drop it (for test)

My PI works very well, connected wireless (USB Ralink and router is a TPLink TD-W8960N). DHCP on Raspberry but router assigns static IP to it (DHCP reserved 192.168.1.200 for it). I can access also outside (webserver on port 80 and routed an external 8987 port to the PI 80). It works, repeat, very w...

Connect ATtiny85 and simulate Arduino without that miniboard

Hi to all! I would buy some ATtiny85 to program with my Raspberry 2. I don't have and I don't would buy an Arduino. I see that it's possible to setup Arduino IDE on Raspberry, ok, but every guide that I did find say next step to connect the Arduino to the PI. But.. I don't want connect an Arduino......

Re: Controlling 433MHz RF outlets with Android devices

Saw this RFs on Amazon. One question. Is it possible to use them to control wireless a DS18B20? Surfing for several days on the net I'm at this point: 1) With the attiny85 we could read the Temp Sensor and transmit the data on the air (via the transmitter of this kit)... OK, but how we can setup the...

Re: HOWTO: Move the filesystem to a USB stick/Drive

Hi to all! Using from several years this method and it works like a charm (SD for first boot + USB pen drive mounted as / ). cmdline.txt in SD card has root=/dev/sda1 /etc/fstab (on the USB stick) has the following entries AND sdb1 is an error, but it works!!!

Root on USB and distro changing

Hi to all, in one of this days i'll move root partition on USB, and i'll leave on SD only /boot. With this, if i would change distro (e.g. from raspbian to arch, etc), i need only to have a flash drive for every distro i want? E.g., a 4gb for raspbian, another 8gb for openelc etc etc? And only i nee...
