What Is a Raspberry Pi? Here's What You Need to Know

Filed under

When we need an extra computer to perform a specific job for us, it's sometimes too expensive or wasteful to buy a whole new PC or laptop to do the job. Sometimes you just need a small but capable device that can do the job for you, and this is where the Raspberry Pi comes into play.


The Raspberry Pi may have a funny name, but once you get through all the bakery-related puns, you'll find a powerful kit that can do a lot for what you pay for. The Raspberry Pi Foundation invented it as a way to help teach people about coding and the basics of Computer Science.

The device comes with its own unique brand of the Debian operating system called "Raspberry Pi OS." The choice to make the OS Linux-based helps keep the cost down and allows users to have a lot more control over their system, making it a great tool for learning.

Does that mean the Raspberry Pi is for kids? Hardly. Despite the fact that the device itself is the size of a credit card, it can do a surprising amount. It has most of the ports you would expect from a PC, such as USB, Ethernet, and HDMI. As such, when you set it up, it really feels like you're using a desktop PC that shrunk in the wash.

Raspberry Pi Powered BMO Is a Custom Adventure Time TV

Filed under

It all started when Brandon Withrow created a replica of The Simpson’s family TV that plays episodes of the classic cartoon. The idea took the Raspberry Pi community by storm and makers everywhere have started making their own cartoon-themed TV projects. Today the adventure continues as we have this awesome BMO-themed TV project to share created by a maker known on Reddit as Davidforthewynne.

This project features a shell shaped like the Adventure Time character BMO. When the Pi inside boots, you get a glimpse of BMO’s face on the desktop before it begins to play episodes of Adventure Time.


Inside you’ll find a Raspberry Pi Zero running Raspberry Pi Video Looper to continuously show episodes. It features a power button capable of safely shutting BMO on and off, a 7-inch screen for the face and has a speaker mounted to the back for audio output.

If there’s one thing we can say definitively, it’s 'rhombus'. This project is algebraic! The best Raspberry Pi projects are ones you can recreate at home and this is one of them. To get a closer look at how it all goes together, check out the original thread shared to Imgur and be sure to follow Davidforthewynne for more cool projects.

Ubuntu-based Pop!_OS Spotted on Raspberry Pi

Filed under

The scent of a Raspberry Pi port can be traced to Twitter, where System76’s Principal Engineer and Pop!_OS maintainer Jeremy Soller recently posted a photo showing the 64 bit OS apparently running on a stock Raspberry Pi 400. More tellingly, he also shared a link to a repository full of Pop!_OS packages for ARM devices.

For those not already familiar, Pop!_OS is an Ubuntu-based OS that’s free and open-source, with a custom Gnome desktop known as COSMIC. It’s maintained by System76, a computer builder operating out of Denver, Colorado, that sells laptops, desktops and servers, all with either Pop!_OS or Ubuntu installed. They’re quite keen on Linux there, it could be said.

Pop!_OS is notable for its support of AMD and Nvidia GPUs with no additional tinkering, and its auto-tiling desktop, which fills your display with app windows. A tabbed, web-browser-like, look is also available, along with a complete set of keyboard shortcuts to move windows around. It has a 7.5% share of all Steam installations on Linux, according to the Steam Hardware Survey.

    The company also introduced the “Feather Starter Kit for Swan” that enables the board to work with the company’s Notecard LTE Cat-M/NB-IoT M.2 modem that ships with 10-year (up to 500MB) of IoT connectivity, as well as GPS/GNSS connectivity.

  • 3D Printed Preschooler Proof MP3 Player Takes A Beat-ing

    Prototyping new ideas can be a lot of fun, but putting new projects in a durable enclosure can be a difficulty. This is especially the case when the user of this product is one of the most destructive forces in nature: A toddler! This is the circumstance that [blue blade] found himself in when he wanted to build a durable MP3 player for his grandson, and you can see the results of his work below the break.

    The hardware is simple: A 16850 lithium-ion battery powers an MP3 Decoder/Amplifier module that plays MP3s stored on a Micro SD card. A speaker, power switch, and micro USB powered battery charger complete the build. What stands out most is the enclosure. Why?

    When children are involved, durability isn’t a matter of product lifetime, it’s also a matter of safety. Items that are easily broken aren’t just useless, they can be dangerous. With this in mind, [blue blade] built a brightly colored enclosure with extra thick walls joined by metal bolts. Externally, a rounded cover bolts over the charger connector and Micro SD card slot. The only other protrusion is a lighted rocker switch for powering the MP3 player on and off.

  • Raspberry Pi Launches New Website For Its Hardware

    In a surprise move, Raspberry Pi today announced that a new website has been created to support Raspberry Pi devices, sales and documentation. This marks a change from a single website from 2011 which served both educational outreach and sales. Another change is Raspberry Pi’s social media presence, with the original Raspberry Pi twitter account focusing on the hardware, and another representing the charity and educational outreach of the Raspberry Pi Foundation.

    Raspberry Pi Trading and the Raspberry Pi Foundation have long been separate entities. Raspberry Pi Trading is responsible for the hardware engineering and sales of Raspberry Pi while Raspberry Pi Foundation is a charity that provides educational outreach such as learning resources and teacher outreach program “Picademy”.

    In two blog posts, one written by Liz Upton, executive director of communications for Raspberry Pi Trading, and another from Philip Colligan chief executive of the Raspberry Pi Foundation, we learn that the division is a necessary step as the user base grows and their requirements change. The new website aims to serve those interested in the Raspberry Pi hardware and software and provides documentation and links to resellers offering official Raspberry Pi boards and accessories.

  • LEONARDO: The Hopping, Flying Bipedal Robot | Hackaday

    LEONARDO, a somewhat tortured name derived from “LEgs ONboARD drOne,” is actually just what it appears to be: a quadcopter with a set of legs. It comes to us from Caltech’s Center for Autonomous Systems and Technologies, and the video below makes it easy to see what kind of advantages a kinematic mash-up like this would offer. LEO combines walking and flying to achieve a kind of locomotion that looks completely alien, kind of a bouncy, tip-toeing step that really looks like someone just learning how to walk in high heels. The upper drone aspect of LEO provides a lot of the stabilization needed for walking; the thrust from the rotors is where that bouncy compliance comes from. But the rotors can also instantly ramp up the thrust so LEO can fly over obstacles, like stairs. It’s also pretty good at slacklining and skateboarding, too.

  • LEONARDO, the Bipedal Robot, Can Ride a Skateboard and Walk a Slackline

    Researchers at Caltech have built a bipedal robot that combines walking with flying to create a new type of locomotion, making it exceptionally nimble and capable of complex movements.

    Part walking robot, part flying drone, the newly developed LEONARDO (short for LEgs ONboARD drOne, or LEO for short) can walk a slackline, hop, and even ride a skateboard. Developed by a team at Caltech's Center for Autonomous Systems and Technologies (CAST), LEO is the first robot that uses multi-joint legs and propeller-based thrusters to achieve a fine degree of control over its balance.

  • PICMG spec standardizes links between IoT controllers and sensors

    PICMG has ratified an “IoT.1” firmware spec for standardizing plug-and-play communications between IoT controllers and sensors and effecters. The spec works with PICMG’s recent microSAM MCU module form factor.

    PICMG, which is known primarily for its COM Express standards, has released its first draft of a firmware spec for Internet of Things connectivity at the sensor level. The IoT.1 spec is primarily concerned with microcontroller connections with sensors. However, starting with IoT.2, the spec will extend upward to industrial controllers and IoT gateways that runs Linux or Windows on COM Express modules and other PICMG form factors.

  • Instantly test your cables by plugging them into this device | Arduino Blog

    Cables come in a wide variety of styles and attempting to diagnose a potential fault in one of their tiny wires can be tricky, especially without access to fancy test equipment. To combat this problem, TechKiwiGadgets created a small device called the Touch Screen Cable Tracer, which has several varieties of connectors on both ends that allow for a USB and RJ45 cable to be plugged in and subsequently tested.

    The board selected for this project was an Arduino Mega due to its large amount of RAM and GPIO pins. Placed on top of this was an ILI9325 2.8” TFT screen, which shows the menu for the cable tracing device and the current state of the attached cable. TechKiwiGadgets also designed, fabricated, and assembled a custom cable tracer shield that snaps onto the Arduino and exposes a mirrored set of connectors on either end.

  • Intel Continues Optimizing Linux For Optane DC Persistent Memory Servers - Phoronix

    With the Linux 5.15 kernel there is a patch to benefit tiered memory systems with a focus on servers having persistent memory. That patch is demoting pages during page reclamation to slower tiers of memory such as Optane DC persistent memory. Intel continues building on that and other persistent memory kernel work for plumbing the kernel with optimized memory placement for these modern servers.

    Intel engineer Huang Ying sent out the latest patch series this week that tunes the Linux kernel's NUMA balancing behavior to optimize memory placement for memory tiering systems. These patches are further optimizing the kernel's dealing of pages in the presence of persistent memory while keeping the most important pages in DRAM.

  • Linux 5.16 To Add Intel Encrypted PXP, Alder Lake S Declared Stable & Ready - Phoronix

    A new batch of Intel kernel graphics driver code was mailed out today to DRM-Next for staging ahead of next month's Linux 5.16 kernel merge window. Lots of notable changes in this pull!

    This batch of code updates for the Intel DRM kernel driver in Linux 5.16 is bringing the following changes:

    - Intel's encrypted Protected Xe Path (PXP) is landing in mainline finally. Intel PXP works with Gen12 and newer as a hardware-protected session for clients on Xe Graphics with encrypted video memory and leveraging a trusted execution environment to protect these sessions from other clients. PXP on Linux has been in the works for a while but now is finally ready for mainline in Linux 5.16. The Mesa changes for PXP are pending and should be merged once the kernel bits are in mainline.

    Oculus is part of Facebook, a company that does many evil things including surveillance, censorship and tax avoidance, The Quest cannot be used without a Facebook account and it runs Android, a nonfree OS. Installing a free OS such as PureOS or the GUIX system seems to be impossible, since the bootloader is most likely locked down. Of course I don’t want to play nonfree games such as VRChat, which most likely spy on the player. By contrast VSekai is free software built on top of the Godot engine. The Godot engine runs on my Talos II and most likely it will also run on the Librem 5, and future hardware based on the Libre-SOC which I have been contributing to. Cardboard is great if ungoogled.
