RealVNC works great within the LAN, but if you want to access a pi outside the LAN, you'll need something like remote.it as well. You can set it up either as Peer-to-Peer or through the remote.it servers. I prefer the former. It works well for SSH, but RealVNC can be a bit clunky if you have a slow ...

There's the MAC address:
B8:27:EB:xx:xx:xx for RPi 3 and less
DC:A6:32:xx:xx:xx for RPi 4

The xx:xx:xx sequence of hex numbers is unique.

One easy way to get them is using Fing.

That's a very informative article, thank you.

But you didn't mention that you can use Arduino straight out of the box, whereas with Pico, you must solder the pins in first.
The idea of wielding a soldering iron anywhere near a computer has been a major put-off for me.

Exactly what I was looking for.
Thanks cleverca22 and klricks

I have an RPi 3B+ running a weather station in a remote location. There are frequent power cuts. When the power is restored, the RPi boots up before the modem has finished doing its thing, so the RPi has nowhere to get the time from. It assumes the time is what it was when the power went off. This i...

Just a warning if you're planning to use the Adafruit Stemma Soil Moisture Monitor:
https://www.adafruit.com/product/4026

It simply does not work. In my tests, there was no difference between wet and dry soil. An utter waste of money.

I've used gnuplot extensively in my website: www.tideman.kiwi.nz To get help, I just use Google with searches like "gnuplot multiaxis". You usually get lots of hits. I got started using this text: "Gnuplot in Action" by Philipp K Janert, but I quickly grew out of it and I haven't...

I've had a Sense HAT attached to a Pi4B for more than a year with no problems. Attached plot shows the temp range from the Sense HAT for a few days compared to temps from a weather station alongside. You can see that they track each other quite well, but there are daily spikes in the Sense HAT recor...

I avoided all this hassle, by simply setting the static IP in the router.

I'm guessing he's from New Zealand, from his userid. I recommend he use Element 14 which supplies goods to NZ out of Singapore - next day service, or a few days depending on stocks. RPi 4B+ 2GB is NZ$64, with free delivery if your order is more than NZ$100's worth. Adding case, HDMI cable, & PSU...

Mmm.........
"All around the world", but he's only going to be 7,000 km from home.
Living down here in the antipodes, even Singapore is more than 7,000 km away.

Some people's idea of "the world" is a bit parochial.

TideMan

Thanks fruitoftheloom that fixed it.

I'm trying to install obspy on my RPi 4B under Buster.
I've tried:

Code: Select all

sudo apt install python3-obspy
pip3 install obspy
conda install obspy

but none of them work for one reason or another.

Does anyone have a suggestion?

TideMan

This might also help someone.......... We just upgraded from a 40" Samsung TV to a 55" LG OLED TV. On the Samsung, we could stream from an RPi 4 running Buster with no problems at all. But on the LG OLED, the overscan was so bad, we simply couldn't use it - we couldn't even see the raspber...

I switched from xrdp to realVNC for Buster because xrdp didn't work.

I haven't had your specific problem, but I've had others relating to using the hostname.
These turned out to be Windows playing funny buggers with mDNS.
My present version of Win 10 works OK, but earlier versions did not.

I've just been playing with MSMTP using gmail as the mail server. But I had problems getting gmail to accept my password. It gets its knickers in a twist about an insecure app trying use the account. Then I discovered the concept of "16-character app passwords" here: https://support.google...

Running Buster on an RPi 4, this happens automatically: If ethernet is connected, that is what is used by default for web traffic for example. If there is no ethernet, wifi is used. But, if ethernet is connected, I can SSH in using either wifi or ethernet (depending on which IP address I use). So, I...

Now to answer your question... sudo pcmanfm ^^^ That opens the file manager as the root user, and any text files opened using it will also be run as root. Be careful! ;) Interesting........... Rather than invoking sudo everytime I want to edit index.html or whatever, I use chmod to change permissio...

Re-image your SD card and start afresh.
And be more careful with your password next time.

OK, so that's basically what I did. BUT it didn't work in a terminal opened in realVNC. However, it works when I connect using SSH, though there are no colours. Turns out this is controlled by puTTY. And when I try it on a RPi connected to a TV, it works AND I get colours. So......... The terminal y...

Is it possible to get a font like Noto Color Emoji in the terminal? I've installed the .ttf file in .fonts and I can get it in the text editor, but not the terminal. In a terminal (with the usual Mono Regular font), using: curl http://wttr.in/christchurch?format=4 I get the current weather condition...

Since it's running headless, VNC unfortunately doesn't work. This statement makes no sense to me. All my RPis (all 7 of them) are running headless with realVNC. You can use remote.it https://remote.it/ to get into your network with both SSH and VNC and they have a special facility for RPis. There a...

Without the comma, you could interpret it as:
Item 1: NOOBS
Item 2: Raspbian and third party....
With the comma there's no possible confusion.

You sure get a prize for vaguity....... For me, running Buster (and before that Stretch) headless using RealVNC over ethernet, in the top taskbar there is a pair of up and down arrows. Hovering on that gives the ethernet details. If I'm on running wireless, it is a radiating set of circle segments. ...
