M5Stack releases local server implementations of UIFlow visual programming Web IDE

Visual programming is now a very popular method to teach programming to kids and M5Stack relies on UIFlow for their ESP32-based IoT development kit. Like most other companies, M5Stack provides either a Web IDE accessible from their server or a desktop program available for Windows, MacOS, or Linux, but the company has now released a local server implementation that allows users to run a Web IDE instance in their local network. The local server is available for Windows 11 x64, MacOS, Ubuntu 22.04, and Linux Arm (e.g. Raspberry Pi), so I downloaded the Ubuntu version to give it a try on my laptop. Somehow the Ubuntu release is full of Windows DLLs, but let’s ignore that for now, and the README.txt tells us to install one dependency and run the program as follows:

apt install ttf-mscorefonts-installer
./UIFlow.Server.Desktop

1 2	apt install ttf-mscorefonts-installer ./UIFlow.Server.Desktop

A window pops up letting us start or stop the server. It can be accessed with […]

Add Z-Wave LR (Long Range) to Raspberry Pi or Home Assistant Yellow with Zooz 800 Series USB stick or GPIO Module

Z-Wave Long Range Raspberry Pi Home Assistant Yellow

We wrote about the new Z-Wave Long Range (LR) standard aka “Z-Wave Plus LR” promising four times the range and 10-year battery life in September 2020 but hadn’t heard much about it since then, at least until now, as Zooz has launched the ZST39 LR USB Stick and ZAC93 LR GPIO module based on a Z-Wave 800 Series chip, with the GPIO module compatible with Home Assistant Yellow and Raspberry Pi SBCs. Zooz 800 Series Z-Wave Long Range GPIO Module ZAC93 LR ZAC93 LR specifications: Z-Wave Frequency – 908.42 MHz (US, CA, MX) / 921.4 MHz (AU, NZ) / 868.42 MHz (EU) Wireless Range – Up to 1 mile/1.6 km in open space with Long Range enabled (up to 300 meters in open space, up to 76 meters indoors in traditional mesh networks) Support for up to 200 devices in a single network Host interface – 10-pin header to Raspberry […]

KiCad 7.0.0 release – Custom fonts, text boxes, SpaceMouse, crash reporting, and much more

KiCad 7.0.0 open-source EDA software has just been released with a range of new features from custom fonts to 3Dconnexion SpaceMouse integration to opt-in Sentry crash reporting, and many more. It took over three years between KiCad 5.0.0 and KiCad 6.0.0 announcements, but only a little over a year for the release of KiCad 7.0.0. Did KiCad developers acquire superhuman abilities or did AI get involved in the development somehow? Most probably not, and instead they change the release schedule to a yearly one, so we should get annual releases of the open-source EDA suite going forward, with KiCad 8.0.0 to be released in Q1 2024. Some notable changes to KiCad 7.0 include: Custom Fonts support is now available in the schematic, PCB, and worksheet editors to allow the use of any system font. Text box support was added in both the schematic and PCB editors. 3Dconnexion SpaceMouse support in […]

ESP32 MPY-Jama is a MicroPython IDE for ESP32 boards

ESP32 MPY-Jama is a cross-platform MicroPython IDE specifically designed for ESP32 boards with a file manager, a REPL terminal, real-time dashboards, and various ESP32-specific features. The IDE is an open-source Python program using pyWebView and pySerial plus some JavaScript for the user interface, and the developer of the program, Jean-Christophe Bos, provides binaries for Windows 64-bit and macOS 64-bit Arm or x86. It’s also possible to use it in Linux but needs to be built from source. Some of the key features of the ESP32 MPY-Jama IDE include: MicroPython code editor with syntax highlighting REPL interface Access to information dashboards with real-time data about WiFi and Bluetooth connections, system info with GPIO status, CPU frequency, memory and SPI flash details Easy 2-click methods to connect to WiFi and create an access point Graphical interface to install a new firmware through esptool Ability to create, import, and run “Jama Funcs” mini-applications […]

Orange Pi OS – An Android-based desktop OS with Windows 11’s look and feel

Orange Pi OS Android Windows 11 interface

The manufacturer of Orange Pi boards, Shenzhen Xunlong Software, has formally announced the release of Orange Pi OS based on Android with a Windows 11-styled desktop that we are told can also be switched to macOS look and feel, and offering features typically found in desktop operating systems such as multi-window support. I understand the current release of the operating system works on Orange Pi 800 keyboard PC and the Orange Pi 5 SBC should also be supported once soon. We’re told Orange Pi OS is based on Android 12, but that may be an error since I’m not aware of an Android 12 SDK for the Rockchip RK3399 processor. The company plans to release an Arch Linux Arm version named Orange Pi OS (Arch) as well as an Open Harmony variant called Orange Pi OS (OH) next year. Orange Pi OS highlights: Design similar to Windows 11 with a […]

Luxonis OAK-D series 2 USB and PoE cameras integrate 3D depth and AI for robotics applications

Luxonis OAK-D Series 2 are the second-generation of USB or PoE cameras with 3D depth and a built-in AI accelerator mostly used for computer vision in robotics applications. We first wrote about Luxonis’ DepthAI module for Raspberry Pi based on the Intel Myriad X AI accelerator in 2019, and later found the module integrated into OpenCV AI Kit Lite, aka OAK-D Lite camera. The second-generation OAK-D cameras replace the module with a Robotics Vision Core 2 (RVC2) “chip-down design” equipped an SoC and Myriad X AI accelerator for up to 4 TOPS of processing power, including 1.4 TOPS for AI inference. Luxonis OAK-D Series 2 specifications and features: Robotics Vision Core 2 based on Myriad X AI accelerator 4 TOPS of processing power (1.4 TOPS for AI) Video encoding – H.264, H.265, MJPEG @ 4Kp3, 1080p60 Computer vision – Warp/dewarp, resize, crop via ImageManip node, edge detection, feature tracking, custom […]

Arduino IDE 2.0 is now officially released

The first stable release of Arduino IDE 2.0 is now out. Based on the Eclipse Theia framework, the new IDE provides a more modern and user-friendly user interface, faster compilation time, and more features we’ll discuss in this post. Arduino initially introduced the Arduino IDE 2.0 beta in March 2021 with a live debugger with breakpoints support, a revamped user interface with features such as autocompletion of variables and functions. After 18 months of debugging with the help of members of the community such as Paul Stoffregen (the maker of the Teensy boards), the Arduino IDE 2.0 is not an experimental software anymore, and it’s the first version you’d see in the download page. The Arduino IDE 2.0 is available for Windows 10 64-bit and newer, Linux X86-64, and macOS 10.14 “Mojave” or newer. If you’ve already installed Arduino 1.x, it will inform you of updates for your installed libraries […]
