My Raspberry Pi 3B+ is reaching nearly exactly 20x (twenty times) slower upload and download speeds than any other PC or device attached via wire to the very same network / router:
As it turned out this is normal and expected due to several reasons.
Read More “True Raspberry Pi’s network speed”Ultibo is the very new / completely different way of programming for Raspberry Pi. You are no longer installing any kind of Linux on your RPi and writing some app or script for it.
Instead:
Developing anything from scratch sounds like a extremely huge and overwhelming task. More like inventing the wheel again. Well… not necessary.
Read More “The “start here” point in Ultibo”If you’re developing your own applications for Raspberry Pi:
There’s a never-ending question on testing your results.
Copying:
Doesn’t seems to be a huge problem.
But, when you have to do this dozens of times each day than an emulator-like questions appears.
Read More “A very quick introduction to QEMU”I made my first project in Ultibo and compiled some example one. Everything was just fine (actually — perfect), if not for that green border with Ultibo name and release version.
Don’t get me wrong. I already love UItibo and will spread the word. But, for security reasons, I’d like to get rid of any info that clearly communicates what was used to build particular piece of software.
Fortunately, with a small research (here and here), it turned out that the solution is very easy.
Read More “Border-less full-screen console app in Ultibo”There are a lot of displays for Raspberry Pi. We can list them by image technology:
And by connection method:
There are a lot of arguments and parameters to consider when picking one that is best for you:
I have decided to buy the last one because it was purely for testing purposes.
Read More “3.5 inch GPIO display and RPi”In this quite old article I have provided just a typical non-sense introductory blah, blah about playing with Raspberry Pi. People who hasn’t done anything yet to their RPi box where sent there to the original “Get started with Raspberry Pi” article at the RPi’s homepage.
Now, it is time to write my very own “getting started” article. A short list-command memo of what should be considered after you unpack, power up and access via SSH your next RPi box.
Read More “Get started with Raspberry Pi”As in this article, you cannot login as a root user in Raspberry Pi (neither locally nor via SSH), because you don’t know the default’s root password. In this article, I’ll show you how to change it to be able to login to it, but only locally (still no SSH access), which is good.
Again, as in here, you should never, ever access or use root account. Instead you should use pi user (after changing its default password) and elevate it to superuser with sudo su or by casting sudo in front of each console command.
I don’t like unnecessary blah, blah and I don’t like blogs bloated with ads, so I decided to steal this source and transform it into a simple list of default logins and passwords on various Raspberry Pi bases and clones.
All the glory (copyright and authorship) goes to tutorials-raspberrypi.com.
You read more about users at base Raspberry Pi (no clone) here.
Read More “All Raspberry Pi default logins and passwords”I started playing with Raspberry Pi some time ago, but it was only at the very beginner level of setting up RPi OS. If you would like to go further and play a little bit with the hardware (but you never did so) here is a bunch of interesting links out there, just to start.
Read More “Playing hardware with Raspberry Pi”Depending on: project’s scope, business expectations, your knowledge and Raspberry Pi’s role you can develop software for RPi in mainly three ways:
All of the above require you to:
And, if you really want to get your hands dirty and truly have no limits then you must forget about Linux and start thinking about Ultibo (there’s a separate article for that).
Developing in Ultibo (or similar complete embedded development environment) requires a lot of expertise, development knowledge and practice. And simply isn’t an option for all. Especially, if you only need to build a quick-and-easy app for RapberryPi. For these purposes this article lists details about RPi development.
Read More “Developing applications for Raspberry Pi or Linux”There are dozens of articles similar to this, so I treat it just as another quick memo for myself:
And if anything above is not for you then maybe a… non-Linux solution for your RPi?
Building apps that will be run on Raspberry Pi will require you in most scenarios to:
If you:
Then you need to get your hands dirty, forget about Linux and start thinking about Ultibo.
Read More “Developing for Raspberry Pi with Ultibo”The variety of original Raspberry Pi editions and thousands of its clones may be a little bit overwhelming.
If you have a problem selecting proper gear box for your scenario or solution this article may help a little bit. I’ll suggest basic components (Raspberry Pi 4’s version, some case and SD card) and a good looking, promising operating system.
Read More “Raspberry Pi-based computer for 80 USD or less?”If your Raspberry Pi-based Flightradar24 data feeder runs 24/7 and yet your public stats still looks like this:
Then you need to do a little tweak to Pi24 configuration and problem should be easily resolved.
Read More “Scattered data sent to Flightradar24”After a nearly five years of struggling with hardware and software for feeding data to Flightradar24, I have finally decided to give it a try with Raspberry Pi. On contrary to what some of you may think, this is not a guide on how to achieve it. The original text is very good and quite self-explanatory. No need to copy it here.
In addition to feeding data to Flightradar 24 there are hundreds of ideas how can you use your Raspberry Pi. With this article I wanted to show you (and remind to myself) just of a few IMHO most interesting ones.
If you’re just unpacking your first Raspberry Pi then better read these two articles:
