MicroBlocks is a visual programming IDE for 32-bit microcontrollers

MicroBlocks is a visual programming IDE for 32-bit microcontrollers currently supporting the BBC Micro:bit V1/V2, Calliope mini (aka the German Micro:bit), Adafruit Circuit Playground Express and Bluefruit, Raspberry Pi Pico and Pico W, and various other boards including ESP32 and ESP8266-based boards. I discovered MicroBlocks in the list of talks for FOSDEM 2023, and although it did not make it to my virtual schedule, I thought it was interesting to look into and write about it. In their upcoming FOSDEM talk, Bernat Romagosa and Kathy Giori refer to MicroBlocks as small, fast, and human-friendly with development guided by four guiding principles: liveness, parallelism, portability, and autonomy. The IDE is inspired by Scratch, and as such, looks very similar to other visual programming interfaces I have used over the years. You can launch MicroBlocks from Google Chrome or Microsoft Edge on a PC (not a mobile device) without having to install […]

FOSDEM 2023 schedule – Open-source Embedded, Mobile, IoT, Arm, RISC-V, etc… projects

After two years of taking place exclusively online, FOSDEM 2023 is back in Brussels, Belgium with thousands expected to attend the 2023 version of the “Free and Open Source Developers’ European Meeting” both onsite and online. FOSDEM 2023 will take place on February 4-5 with 776 speakers, 762 events, and 63 tracks. As usual, I’ve made my own little virtual schedule below mostly with sessions from the Embedded, Mobile and Automotive devroom, but also other devrooms including “Open Media”, “FOSS Educational Programming Languages devroom”, “RISC-V”, and others. FOSDEM Day 1 – Saturday February 4, 2023 10:30 – 10:55 – GStreamer State of the Union 2023 by Olivier Crête GStreamer is a popular multimedia framework making it possible to create a large variety of applications dealing with audio and video. Since the last FOSDEM, it has received a lot of new features: its RTP & WebRTC stack has greatly improved, Rust […]

Raspberry Pi Camera Module 3 review – HDR, autofocus, wide angle, and NoIR camera

A few days before launching the Raspberry Pi Camera Module 3 with HDR and autofocus, Raspberry Pi Trading asked me whether I would be interested in reviewing the new modules, and sent me three samples: the standard module, the Raspberry Pi Camera Module 3 Wide, as well as the NoIR version that lacks an IR filter and is better suited for night shots. It took a full week for DHL to send the package to my house, but I’ve now had time to review the new Raspberry Pi Camera Module 3, mostly with libcamera, but also Picamera2, focusing on the new features such as HDR, autofocus, and wide angle. I also had a quick try at the Raspberry Pi Camera Module 3 NoIR but without IR lights. Regular readers know I had already made some DIY camera mounts using empty gum bottles, and I just replaced the Lotte XYLITOL stickers […]

Radxa ROCK 5A SBC – A Raspberry Pi 4 lookalike with up to 16GB RAM, Rockchip RK3588S SoC

Radxa has just unveiled the ROCK 5A single board computer (SBC) following Raspberry Pi 4 form factor and powered by a Rockchip RK3588S octa-core Cortex-A76/A55 processor coupled with up to 16GB of RAM as a way to celebrate Chinese New Year 2023. The Radxa ROCK 5A (aka ROCK5 Model A) closely follows the Raspberry Pi 4 layout, including two micro HDMI ports, a 3.5mm AV port, a microSD card, a 40-pin GPIO header, four USB ports, and a Gigabit Ethernet port. The MIPI DSI connector is there too, and so is the MIPI CSI camera connector, but in a different location. Radxa also added some features such as an M.2 socket for a wireless module (since there’s none on board) and eMMC flash module connectors, among other smaller changes (e.g. Power button!). ROCK 5A specifications: SoC – Rockchip RK3588S CPU – Octa-core processor with 4x Cortex-A76 cores @ up to […]

Making a DIY Raspberry Pi camera mount with privacy mode!

I’ve just repurposed an empty XYLITOL gum bottle into a DIY camera mount for the Raspberry Pi Camera Module 3 with privacy mode to boot… In order to avoid confusion, while Xylitol is a chemical compound, it’s also a Japanese brand of chewing gums (Lotte XYLITOL) that is sold in Thailand and other countries. I’m specifically talking about the latter in this post. Raspberry Pi Trading has just sent me a bunch of Raspberry Pi Camera Modules 3 for review, and since I don’t have any camera mount I initially thought maybe I’ll laser cut some mount or use some LEGOs as I did with the e-CAM20_CURB camera for Raspberry Pi 4. But then I saw some empty XYLITOL gum bottles, noticed the cap would open vertically, and it seemed like the modules might fit in there as well. And indeed they do with the Raspberry Pi camera modules snugged […]

Raspberry Pi Camera Module 3 launched with autofocus and HDR

Raspberry Pi Trading has launched the Camera Module 3, their first camera module supporting autofocus and HDR, designed to work with all Raspberry Pi boards that can take a camera, and offered with either a standard or wide field-of-view, and an optional infrared cut filter. All four variants of the new camera module are equipped with a Sony IMX708 12MP sensor that supports high-dynamic range (HDR) and features phase detection autofocus. The Camera Module 3 has the same X/Y dimensions and mounting holes as the popular Camera Module 2 launched in 2016, but is several millimeters taller due to the improved optics. Raspberry Pi Camera Module 3 specifications: 12MP Sony IMX708 back-illuminated and stacked CMOS image sensor Sensor size – 7.4mm diagonal Pixel size: 1.4μm x 1.4μm Resolution – 4608 x 2592 pixels FoV – See comparison table between different models below Common video modes: 1080p50, 720p100, 480p120 Autofocus system: […]
