CrowPi2 Raspberry Pi 4 Education 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 battery charge out of the box, and can be charged …

UPX-Edge BrainFrame Edge AI DevKit Targets Smart Video Analytics

UPX Edge Embedded Computer

AAEON UP Xtreme Edge (UPX-Edge) is a rugged embedded computer built around the company’s UP Xtreme SBC with a choice of 15W Whiskey Lake-U processors ranging from Celeron 4305UE to Core i7-8665UE, and optional Intel Movidius X AI accelerator cards. We previously noted the company had launched UP Xtreme Smart Surveillance kit integrating Milestone video management software (VMS) and SAIMOS video analytics software to the embedded computer. AAEON has now partnered with another company – AOTU.AI – to announce the launch of the BrainFrame Edge AI Developers Kit (DevKit) aiming to help developers and system integrators to rapidly create and deploy Smart Vision applications. The solution relies on UP Xtreme Edge mini PC fitted with an Intel Core i5-8365UE processor and 16GB RAM, 64GB eMMC flash, and two Intel Movidius Myriad X VPUs. We’ve also gone through Up Xtreme Edge specifications, so let’s instead focus on the software. This is how aotu.ai describes BrainFrame smart video analytics platform: BrainFrame is …

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

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 card with Raspberry Pi OS and install a Python script …

MEGA-RTD Raspberry Pi HAT Offers up to 64 Resistance Temperature Detectors (Crowdfunding)

Sequent Microsystems like to make stackable Raspberry Pi HATs. After their stackable 4-relay board allowing for up to 32 relays controlled by a Raspberry Pi board, the company has now launched MEGA-RTD 8-channel RTD Raspberry Pi HAT enabling up to 64 resistance temperature detectors via 8x MEGA RTD board stacked on top of a Raspberry Pi board. If you haven’t heard about this type of temperature sensors, we wrote a post explaining the advantages and drawbacks of resistance temperature detectors last year. Basically, those temperature sensors contain a resistor that changes resistance value as their temperature changes, and support much wider temperature ranges than traditional temperature sensors such as DHT22 while keeping a <0.1°C accuracy. The price of the sensors themselves is similar to traditional sensors, but the total price is more expensive since they require extra hardware to measure the resistance/voltage value. MEGA-RTD key features and specifications: MCU – STMicro STM32F030 Arm Cortex-M0 microcontroller handling I2C commands from Raspberry …

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

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 the package are some “Minecraft carton papers” and the user …
