Suggested January 2024 Review Of Picore – A 25Mb Os For The Raspberry Pi

Tiny Core is a minimalistic Linux distribution and piCore is the Raspberry Pi port. piCore runs entirely from RAM which means there is no installation process, in conventional terms. However, you are able to install programs (often called extensions in piCore’s nomenclature) which are saved onto a second partition on the SD card. Programs can be installed permanently on the SD card or they can be registered with the OS and then downloaded only when they are run.

There are three versions of piCore available, the simplest vanilla version, with no GUI or default SSH access; the vanilla version with SSH access; and the GUI version with a lightweight desktop. The most useful of the three is the last one and the one we will use here.

At the time of writing, piCore 5.3 is the latest version, however you can check the release announcements here. Download piCore-5.3-X.zip and unzip the file. You will also need to download Win32 Disk Imager. Extract the files from the Win32 Disk Imager kit.

Because piCore is a small Linux distribution, it will fit on small SD cards. I used a 1GB SD card, but a 512MB card would be sufficient. Insert the SD card into a card reader and run “Win32DiskImager.exe”.

The writing process shouldn’t take too long (less than one minute) as there isn’t much data to write! Eject the card safely from Windows, insert into your Pi, and power on.

Once piCore is booted, you will need to expand the data partition to fill the rest of the SD card. If you don’t do this then you won’t be able to install any additional apps. This must be the first thing you do, if you attempt any other operations at this point, you could make the system unstable.

By default, the SD card has two partitions, one is the boot partition, the other is the data partition for the extensions. The first partition is used during boot and is then unmounted. This ensures that the system always boots clean and fast. The second partition is only a few megabytes by default and needs to be expanded.

sudo

fdisk

/

dev

/

mmcblk0

Now list the partitions using the “p” command. The output will look something like this:

Take note of the Start cylinder for the partition “/dev/mmcblk0p2”, in this case 705. Now delete the second partition using the “d” command. This sounds drastic but this is the first step in re-sizing the partition. Now re-create the partition using the “n” command. Enter “p” for primary partition and 2 for the partition number. Enter the start cylinder number that you jotted down earlier, in my example 705. Accept the default last cylinder as this will give you the largest possible size for the partition. Write the new partition table to the disk using the “w” command and reboot.

After the reboot, expand the file system using:

There are several different ways to install apps on piCore. The two principle methods are “OnBoot” and “OnDemand”. The “OnBoot” method is the closest to a normal installation that piCore offers. The app is copied into the second partition and at boot time it is installed and made available. The second method only installs the app when you actually run it.

One of the post installation steps will likely be to add some lines to the list of persistent files. Because the boot partition is unmounted after start-up, all the data including the “home” directory and any persistent data (like configuration files) need to be restored from a backup that is stored on the second partition.

piCore certainly is minimalistic. In fact, it could be said it is too bare bones, and to make a working system requires some effort. It doesn’t support any modern web browsers, and the range of available apps is limited. Having said that, its minimalist approach suits the limited resources of the Raspberry Pi very well.

Raspberry Pi 3

Raspberry Pi 3 is an online and open-source website creation tool written in PHP language. It is the most popular open source Content Management System. The Raspberry Pi, 3 Model B, is the first Raspberry Pi model to be open-source from the get-go. The Raspberry Pi 3 is a quad-core, much faster and more capable than its previous Raspberry Pi models.

The new board in Raspberry Pi 3 Model B can play 1080p MP4 video at 60 frames per second, which boosts the Pi’s media center credentials.

The Raspberry Pi 3 comes with built-in Wi-Fi and Bluetooth, which helps to also support the wireless internet out of the box.

The Pi 3 board supports remote updates to Pi. Additionally, you can directly share images of the operating system between multiple computer machines, such as the booting process, using a USB-attached hard drive or pen drive and by supporting booting from a network-attached file system.

Arduino

Arduino is an open-source and prototype platform based on software and hardware. It is easy to use. Arduino is the overall microcontroller motherboard, and it has ready-made software called Arduino IDE (Integrated Development Environment); this software is used to write and upload the computer program code to the physical board.

Some of the features of Arduino areas listed below:

The microcontroller motherboard in Arduino can read the analog /digital input signals from different sensors and then convert those signals into an output process like turning LED on/off, activating a motor, etc.

The user can control a board’s functions by sending signals (set of instructions) to the microcontroller board using Arduino IDE software.

Arduino does not require any extra piece of hardware/programmer whenever to want to load a new piece of program to the board. It can be done by using a USB cable.

Since Arduino IDE uses a more accessible version of C++, it is easy to learn the programming language to program.

Head-to-Head Comparison Between Raspberry Pi 3 and Arduino (Infographics)

Below are the top 6 differences between Raspberry Pi 3 vs Arduino

Key Differences between Raspberry Pi 3 and Arduino

Both are popular choices in the market; let us discuss some of the major differences:

The Raspberry Pi 3 is a series of single Board computers. The single-board consists of a fully functional computer with its dedicated memory, processor, and operating system (runs on Linux). Whereas Arduino is a Microcontroller board, which is less powerful than Raspberry Pi 3 single-board computers, a microcontroller board can be great for quick setups.

The Raspberry Pi 3 is faster than the Arduino, which means Raspberry Pi 3 has 1.2 GHz, whereas Arduino has only 16 chúng tôi helps to process tasks like playing videos, surfing the web, listening to music, etc., very fast compared to Arduino.

Arduino is a simple approach and more attractive for building a project. The Arduino has a convenient and user-friendly time interfacing with analog sensors, motors, or other components, whereas Raspberry Pi 3 has a very complicated path to get sensor readings, such as installing software, libraries, etc.

Designers intended the Raspberry Pi 3 to run operating systems, while they did not design Arduino to operate on any operating systems.

Raspberry Pi 3 vs Arduino Comparison Table

Comparison  Raspberry Pi 3 Arduino

About & Definition The latest version of the Raspberry Pi computer is the Raspberry Pi 3 Model B.

Raspberry Pi is a series of single-board computers. It is a credit-card-sized computer with a low cost, which plugs into a computer monitor or TV, and to operate it, a user can use a standard keyboard and mouse to operate it.

An Arduino is a microcontroller motherboard. A microcontroller is a simple computer in that only one program can be run simultaneously. It is very easy to use.

Arduino is an open-source and prototype platform based on hardware and software which is easy to use.

Board Types

The Raspberry Pi 3 is a series of single Board Computer. The single-board consists of a fully functional computer with its dedicated memory, processor, and operating system (runs on Linux). The Arduino is a Microcontroller board, and this board is not as powerful as Raspberry Pi 3 single-board computers, but the microcontroller board can be great for quick setups.

Microcontrollers are good when it comes to controlling small devices, but it is not possible to run an entire operating system.

Connectivity Abilities

The Raspberry Pi 3 can be connected to Bluetooth devices and the internet right out of the box using Ethernet or by connecting to Wi-Fi. Arduino cannot connect to Bluetooth devices and the internet without a Shield, which adds Internet or Bluetooth connectivity. HATs (Hardware Attached on Top) and Shields help with this process.

Ports available on the board

HDMI port, audio port, 4 USB ports, camera port, and LCD port help in media applications.

Arduino does not have any of the ports on the Microcontroller board.

But it can be achieved by using Shields.

Board Applications

The Raspberry Pi 3 is a set of several -computer; it performs multitask several programs with its Broadcom BCM2837 SoC, which means to build a complex project, needs multiple actions at a time and can be achieved easily using Raspberry Pi 3. It cannot be achieved in Arduino since Microcontrollers have only 16 MHz

Area of usage Raspberry Pi is best to use when a user requires a fully-fledged computer means when the user wants to control a more complicated robot, doing intense calculations, and performing multiple tasks. Arduino microcontroller board can be used for simple and repetitive tasks such as functionality like a garage door opening and closing of it, reading temperature and reporting it to social websites (ex: Twitter), and run a simple robot.

Conclusion

If someone is building a project which involves several functionalities at the same time, requires easy access to the internet, and also needs media accessibility, then Raspberry Pi 3 will be a perfect choice.

7 Ways To Power Your Raspberry Pi Besides The Wall Socket

The Raspberry Pi is really such a neat tiny computer – it’s so small that you can take it literally everywhere! Now if only the same could be said with the power socket. Having the Raspberry Pi power supply connected to a wall socket all the time kind of defeats the purpose of having a tiny computer the size of a credit card.

Luckily, there are other ways to power the Raspberry Pi. Check out the various ways to power up your Raspberry Pi.

Tip: if you just got a new Raspberry Pi, you need to first set up Raspberry Pi OS in order to run anything meaningful on it.

1. Phone Power Bank

Price: roughly $20-100

Powering a Raspberry Pi with a phone power bank is a great way to make your project as mobile as it possibly can without having to shell out a ton of cash. No need for new components – you could even use an old power bank as long as it’s got enough juice left in it. For best results, you’ll need one with at least 2000 mAh to get a good run with the Raspberry Pi.

Pros

Almost always readily-available

Works even better with high-speed charging cables

Cons

Can quickly run out of energy

You might get underpowered running off of a low-current cable

2. A Pair of 18650 Batteries

Price: roughly $30 with power implements

A mainstay power source for many robotics projects, 18650 batteries are reliable, durable, and cost-efficient. To use this on your next Raspberry Pi project, you’ll need at least two of these and a 5v step-down converter or a charging module. Either that, or you can use a single one with a step-up converter, although this won’t be a good idea with the Raspberry Pi 4 which has much higher power requirements than the other versions.

Pros

Can be modified to power other insulated components

Can be connected to a power management circuit

Cons

Requires a lot of electronics knowledge to do

Not so beginner-friendly

Good to know: one of the more interesting project you can do on a Raspberry Pi is to turn it into a video conference station.

3. A 26650 Battery

Price: roughly $25 with power implements

If you’re going to make a custom circuit with li-ion batteries anyway, you’ll get the most juice with a 26650 battery. It’s small enough that you can fit it into a Raspberry Pi rover while having around twice the capacity of an 18650 battery. In fact, you can power a Raspberry Pi for hours with a single one as long as you use a step-up converter.

Image source: Wikimedia Commons

Pros

Has the most power density

Cons

Harder to find components for it than an 18650 battery

4. UPS Hat

Price: $32 without 18650 batteries

The Uninterruptible Power Supply Hat (UPS Hat) is one way you can power a Raspberry Pi without having to consult Ohm’s law every hour. It’s designed as a plug-and-go device that fits right on top of the Raspberry Pi, connected to the GPIO pins. It also has jumper pins on top to let you use the other pins without blocking the way.

Pros

Easy to use

Has battery warning indicators to tell you which side is positive and negative

Cons

Current can drop too low for many Raspberry Pi 4 projects

Note: If you are bringing your Raspberry Pi around, it is best to get a suitable case for your Raspberry Pi.

5. A Regular UPS

Price: $100-300

If you don’t mind connecting your Raspberry Pi to a heavy block of plastic all the time, a regular UPS should work just fine. With a larger power supply unit, you can use your Raspberry Pi for far longer than you would with a regular computer. In fact, you won’t even need to worry about the monitor since the UPS can power it up too.

Pros

Plenty of power capacity

Powers AC components just as well

Cons

Very bulky

6. Power Management Hat

Price: $20 without power supply and RTC battery

The Power Management Hat is one feat of a power supply unit. It features a usable RTC (real-time clock) chip, plenty of protection circuits, and even an ATmega328P SMD chip! Yes, that’s exactly the chip used on the SMD version of the Arduino Uno. It’s programmable, so you can use it alongside the Raspberry Pi as if it were a regular Arduino.

Pros

Almost impossible to break

Beginner-friendly

Has a built-in shutdown feature to automatically turn off the Raspberry Pi

Cons

The ATmega328P and other protection circuits eat up energy

7. Supercapacitor

Price: $15

Perhaps you want a more exotic way to power your Raspberry Pi. Supercapacitors can be used to temporarily power a Raspberry Pi Zero, which takes in a lot less power than a full-fledged Pi 4 or an older Pi 3. Plus, they’re easy to charge. You can use one alongside a regular battery and use it as some sort of a low-power custom UPS.

Image source: Wikimedia Commons

Pros

Works seamlessly with other Raspberry Pi power supply sources

Can be charged while the Raspberry Pi is being used

Protects your Raspberry Pi from sudden dips and surges

Cons

Very low power capacity

Can be pretty expensive

Not beginner-friendly at all

Frequently Asked Questions Why am I getting a low voltage warning on my Raspberry Pi?

You can get a low voltage even if you power your Raspberry Pi power supply outputs 5 volts. That’s because there’s a voltage drop when electricity passes through a cable. The official Raspberry Pi power supply outputs 5.1 volts to account for that voltage drop.

Can I power my Raspberry Pi from a laptop USB port?

NEVER power your Raspberry Pi on a USB port. It won’t work even if you tried, since USB ports max out at 500 mA when you need 3-4 times that amount to run a modern Raspberry Pi. And if you did get to bypass that limit, you’ll essentially fry your USB port.

Why can’t I use 9V batteries to power my Raspberry Pi?

9V batteries run out of power too fast to be useful. Even if you were able to use a step-down converter to bring it down to 5 volts, the Raspberry Pi will just drain that out before it even properly shuts down.

Probably the most common error with Raspberry Pi is a corrupted SD card, mainly due to improper shutdown or power failures.

There is not much you can do when this happens, but we’ve listed an additional option besides the fresh re-install.

For other issues that you might have with your Raspberry Pi, visit our Raspberry Pi errors hub.

Also, we have a lot of useful guides in our

On the first boot, the Raspberry Pi needs an SD card with the OS mounted on it; otherwise, you can’t go any further.

Many Pi boards come with a microSD card with the NOOBS (New Out Of the Box Software) installer; of course, you can also have your own standalone image. Whichever method you use, it is recommended to use an 8GB for SD card or higher.

But what’s most important, is to use a reliable SD card manufacturer. Now, you might probably not know from the start whether you’ve picked the wrong one, but buying only from authorized suppliers and doing some research on recommended SD card brands for Pi might be helpful.

When booting, you will know that there’s a problem with the SD card if the red LED is blinking, while the green LED is not. Or, the green LED can blink regularly (3 to 8 times) to indicate that there’s a problem with the card.

How do I fix the Raspberry Pi SD card issues? 1. Mount a fresh OS image

Format the SD card in another PC, using SDFormatter. (If the formatting fails, the card is broken.)

Get a clean OS or image from here.

Save and insert the card in your Raspberry Pi to see if it works.

This is the standard recommended solution to fix a faulty microSD card. However, users complained that the Pi fails to recognize the card all too frequently and that they have to re-install a fresh image over and over again.

It is very frustrating, which is why the next solution might be helpful, but only after a first successful first boot: namely to make a read-only copy of the OS on a USD stick or another media device.

2. Make a read-only copy of the SD card

Copy the Raspberry image to your SD card.

Boot normally from the card, but

don’t Expand filesystem. Set

up time zone and international settings.

Run sudo fdisk/ dev/mmcblk0 and press p to print the current partition table.

Then enter the following commands:

Modify the /etc/fstab  as follows:

Run sudo partprobe to recognize the partition.

Format the new partition with sudo mkfs –type ext4 /dev/mmcblk0p3

Reboot.

If you then need to make changes to the system, you can remount the read-only partitions with write access sudo mount -o remount, rw /dev/mmcblk0p2 .

Additional info

Users have reported that their SD card was functional when inserted into another Raspberry Pi board – usually an older version than the one that didn’t boot. In the end, they solved the problem with a new card.

Sometimes, just taking the SD card out and rebooting can fix the issue.

It was also mentioned that the plastic holder of the SD card might have been the problem since some Pi version is very picky about these details.
