CrowPi2 Raspberry Pi 4 Education Laptop Review

CrowPi2 Raspberry Pi Laptop Review

I started my review of CrowPi2 Raspberry Pi 4 Learning Kit a while ago and at the time I showed content from the kit and its first boot. I’ve now spent more time with this very special Raspberry Pi 4 laptop and will focus this review on the education part, namely CrowPi2 software, but will also look at thermal cooling under stress with and without a fan, and try to install another Raspberry Pi compatible board inside the laptop shell. CrowPi2 Education Software It’s quite important to read the user manual before getting started as there are a few non-intuitive steps you may have to take. First I assume the wireless keyboard would just connect after pressing the power button, but it did not. The user manual explains the RF dongle is inside the mouse, and once you connect it you’ll be able to use the keyboard that has some […]

Using an Old Cassette Tape to Enclose a Battery-powered Raspberry Pi Zero

Raspberry Pi Zero Cassette Tape Enclosure

If you’re old enough you may have a stock of old cassette tapes that may or may not work anymore. The good news is that if you have time on your hands, you could recycle those as a Raspberry Pi Zero enclosure, including even other components like a small battery, battery charging board, and display. That’s exactly what Martin Mander did with his Cassete Pi IoT scroller project that receives notifications via IFTTT service and displays them as scrolling text on a small display connected to the Raspberry Pi Zero W. Here’s the detailed list of components used in this project: Raspberry Pi Zero Wireless Pimoroni LiPo SHIM LiPo/LiIon power supply shim for Raspberry Pi boards Adafruit Micro Lipo charger board with micro USB port Pimoroni 11×7 LED Matrix 150 mAh Li-Polymer Battery Cassette Tape DPDT Slide Switch Vibration motor Once assembly is done, you can flash a Micro SD […]

Zero Terminal V3 is a Modular Raspberry Pi Zero W Powered HandHeld PC

Zero Terminal V3 Raspberry Pi Zero W Handheld

Hardware hacker NODE has created a slick handheld Linux PC based on the Raspberry Pi Zero W board. About the size of a thick smartphone, Zero Terminal V3 also includes a touchscreen display, a built-in battery, a USB Type-A port, and a microSD card slot. The keyboard found in previous iterations of the Zero Terminal is gone, as the new version focuses on modularity thanks two 40-pin sockets that connect to the GPIO pins, video output, camera connector, USB ports, power indicators, etc… in order to allow people to create and add custom backpacks to change the functionality as needed. Zero Terminal V3 specifications: SBC – Raspberry Pi Zero W with Broadcom BCM2735 ARM11 processor, 512MB RAM, MicroSD card socket, WiFi 4, and Bluetooth 4.0 Display – 5.5″ 1080p AMOLED touchscreen display bought on Waveshare and designed for Raspberry Pi 3/4, but NODE designed an adapter for RPi Zero. Audio […]

Comfile Launches 15-inch Industrial Raspberry Pi Touch Panel PC Powered by RPi CM3 Module

15-inch Raspberry Pi Touch Panel PC

Three years ago, we noted Comfile has made 7-inch and 10.2-inch touch panel PC’s powered by Raspberry Pi 3 Compute Module. The company has recently introduced a new model with a very similar design except for a larger 15-inch touchscreen display with 1024×768 resolution. ComfilePi CPi-A150WR 15-inch industrial Raspberry Pi touch panel PC still features the CM3 module, and the same ports including Ethernet, USB ports, RS232, RS485, and I2C interfaces accessible via terminal blocks, and a 40-pin I/O header. ComfilePi CPi-A150WR specifications: SoM – Raspberry Pi Compute Module 3 Lite (CM3L) with Broadcom BCM2837 quad-core Arm Cortex-A53 processor @ 1.2 GHz with VideoCore IV GPU, and 1GB RAM Display – 15″ LCD with 1024 × 768 resolution, 16.7 million colors, pressure-sensitive touch screen (resistive type) Audio – Stereo Audio Output Connectivity – 10/100M Ethernet, optional WiFi via USB dongle USB – 3x USB 2.0 ports Serial – 1x RS232C […]

CrowPi2 Raspberry Pi 4 Learning Kit Review – Part 1 – Unboxing and First Boot

CrowdPi2 Unboxing Review

Last month, we wrote about Elecrow introducing CrowPi2 Raspberry Pi 4 laptop and electronics learning kit for its launch on Kickstarter crowdfunding website. The company has now sent one of its kits to CNX Software for evaluation and review. I’ll start by checking out the content of the package, and boot it up, before publishing a more detailed review in a few weeks. The package is fairly big and highlights it’s made for kids over 8 years old with close to 100 course resources and over 20 electronics modules. The back of the package list the main features and package contents with for example a 11.6″ Full HD display, Raspberry Pi 4 4GB board running a customized (Linux) system or Retropie for game emulation, electronics components and modules like servos and motors, as well as some resources for gaming including two USB gamepads. The first things we get when opening […]

Raspberry Pi Compute Module 4 Coming Next Year with PCIe/NVMe Support

Raspberry Pi Compute Module 4

The Raspberry Pi 4 features a Broadcom BCM2711 processor with Cortex-A72/A53 cores that makes it competitive against other SBC’s based on Rockchip RK3399 or Amlogic S922X/A311D processors. The new processor also happens to have a PCIe interface, but it’s not exposed on the board since the interface is used by VIA VL805 PCIe USB 3.0 controller for the four USB 3.0 ports on the little computer. At the time, we expected the PCIe interface to be exposed in future Raspberry Pi boards or a Raspberry Pi Compute Module 4. But some people did not feel like waiting and instead hack the Raspberry Pi 4 SBC to access the PCIe interface. That hack is clearly not for everyone though… But based on a recent interview of Eben Upton with Tom’s Hardware we got pretty much confirmation that the Raspberry Pi Compute Module 4 will be coming next year, and expose PCIe […]

GloDroid Brings Android 10 OS to Raspberry Pi 4, Orange Pi SBC’s, PinePhone, and PineTab

GloDroid

The community of developers working on software for single board computers often prefer to focus on Linux support, as companies will often provide Android firmware images. But those Android OS images are often not maintained at all, so we’ve seen some projects like the past such as H3droid bringing a better Android OS to Allwinner H3 and H2+ boards and devices. The project is still using Android 4.4 KitKat and that’s getting old with some apps like the latest version of Kodi not working anymore. But a new project has just been brought to my attention with GloDroid leveraging AOSP to bring Android 10 to various Allwinner based boards and platforms, as well as Raspberry Pi 4B. List of supported Allwinner hardware: Allwinner H3 (32-bit) based – Orange Pi Plus 2 SBC, Orange Pi Plus 2E board, Orange Pi PC Allwinner H5 (64-bit) based – Orange Pi Prime, Orange Pi […]

Mythic Beasts, miniNodes Offer Raspberry Pi 4 Hosting Services

Raspberry Pi 4 Hosting Service

Mythic Beats is the company offering hosting services for the Raspberry Pi website, and following Eben Upton proposal they decided to host the website on eighteen Raspberry Pi 4 boards, fourteen of which used as LAMP (Linux, Apache, MySQL, PHP) servers, as well as two used as static servers with Apache, and the final two used as memory store using memcache. Two days before Raspberry Pi 4 8GB RAM launch, they tested the implementation with “normal” traffic (e.g. around one million visitors a day), and the day of the launch, tens of millions visitors came to the website, and it failed, but not because of a failure of the Raspberry Pi cluster, but instead due to a Cloudflare glitch. This is all explained in Raspberry Pi blog. This is all for internal use, but you could also get your own hosted Raspberry Pi 4 board, as Mythic Beast recently added […]
