CodeBug Connect IoT development board is designed for young makers (Crowdfunding)

In 2015, a UK-based team launched a mini IoT development board called CodeBug. The same team has now come up with the CodeBug Connect IoT Development Board.  CodeBug Connect is a new wearable micro-computer that brings IoT to everyone and aimed at educators and young makers.  Upgrade to the original CodeBug This comes as an upgrade to the original CodeBug. The new development board retains its original cuteness and petite proportions but adds full color to the grid of 5×5 LEDs. The original buttons have been upgraded to mini joysticks, making them more suitable for games. The touch-sensitive, croc-clip connectors ‘legs’ that serve as I/O pins remain, as does the 0.1” header socket. “This year has shown our reliance on connected technology — with CodeBug Connect we wanted to make this technology accessible so everyone can build their own IoT devices and no one is left behind. The technology in our original CodeBug has been used by over a million […]

Raspberry Pi 400 kit ships with 7-inch or 13.3-inch touchscreen display

The Raspberry Pi Foundation has recently launched the Raspberry Pi 4 keyboard computer with impressive performance thanks to a well-designed cooling solution, and I think it’s a great tool for kids (and adults) who may want to carry a Raspberry Pi around. However, you’d still need a display in each location, so until the foundation releases the Raspberry Pi 4000 laptop next year (full disclose: I made that up!), it might be cool to have a portable display coming with the keyboard PC. That’s what Waveshare is offering with two kits combining a Raspberry Pi 400 together with a 7-inch or 13.3-inch HDMI touchscreen display and other accessories. Not quite as portable as a laptop but it gets close. Here’s the full list of accessories in the kits: Raspberry Pi 400 Kit with keyboard PC with UK keyboard (sadly the only layout option for now), power supply, HDMI cable, preloaded microSD card with Raspberry Pi OS, mouse, and Beginner guide.

BBC Doctor Who “HiFive Inventor” Coding Kit aims to teach IoT to kids

In what should be one of the first RISC-V education platforms, the BBC, Tynker, and SiFive have just announced the BBC Doctor Who “HiFive Inventor” Coding Kit that comes with an MCU board with WiFi & Bluetooth and guided lessons for kids that teach them to code for the IoT. The HiFive Inventor board is based on a SiFive FE310 RISC-V microcontroller ( the same chip as found in the HiFive1 board) and an ESP32 Solo module for WiFi 4 and Bluetooth 4.x/5.x connectivity. Just like the BBC Micro:bit, HiFive Inventor provides a kids-friendly edge connector with I/O, an LED matrix, sensors, and more. The kit includes the HiFive Inventor hardware platform, a battery holder for three AA batteries (not included), the HiFive Speakers, an illuminated USB cable for power and programming, and alligator clips to connect the speaker or other add-ons to the HiFive Inventor board. HiFive Inventor board looks to be based on the earlier SiFive Learn Inventor, […]

Petoi Bittle Palm-sized Robot Dog uses Arduino and Raspberry Pi for STEM education (Crowdfunding)

You’ve probably already watched a video featuring Boston Dynamics Spot, a headless robot dog used in various industries including healthcare, public safety, construction, oil & gas, etc.. It could also be yours if you wanted a robotic pet dog at home, as long as you have $75,000 US to spare. Petoi Bittle looks eerily similar, but it’s much smaller as it fits in your palm, and could be yours for $225 on KickStarter as a kit to assemble yourself that you may get as soon as December. Bittle robot dog is designed for STEM education and can be programmed using the Arduino IDE, Python, or even Codecraft visual programming IDE. Bittle is comprised of 4 main hardware components: Plastic parts and fixtures – Body, four legs,  head (which can be used to hold Arduino modules), springs, screws, etc… Actuators – 9x P1S servo with a controllable angle of 270 degrees, eight of which are used for walking joints, and the […]

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 […]
