Windows 11 announced with widgets, Android apps support, new system requirements

As expected, Microsoft has formally announced Windows 11 operating system that’s basically Windows 10 with a new look, and some extra features such as Snap Layouts, Snap Groups, and Desktops to further improve the multitasking experience. Snap Layouts and Snap Groups will allow you to select pre-defined layouts to quickly arrange windows as you see fit, and you can define multiple “Desktops” for work, gaming, or school, etc… Other changes include Chat from Microsoft Teams integrated into the taskbar, new gaming features such as DirectX 12 Ultimate, Direct Storage for faster loading, or Auto HDR, a new Microsoft Store with support for Android apps through the Amazon Appstore, and AI-powered widgets to display useful information like calendar, weather, news, stock quotes, etc… There are also features that have become deprecated or pushed to the wayside with, for example, Cortana not used anymore during installation and not pinned to the taskbar, […]

Combining OSTree and SW Containers for reliable IoT Device updates

CNXSoft: This is a guest post by Drew Moseley, Technical Solutions Architect at Toradex, explaining how the company updates Linux IoT devices firmware with OSTree (aka libostree) open-source operating system build and deployment tool, as well as Docker software containers. Every day more and more connected devices are being brought to market and estimates for the total size of the Internet of Things (IoT) market are as high as $1.5 trillion by 2027. Gas pumps, medical devices, and point of sale systems are increasingly connected, making it virtually impossible to avoid interacting with these devices, even for complete Luddites. In the home, devices such as power meters, light switches, and security cameras are commonly internet-enabled allowing for smart home functionality. The level of complexity in the software for these devices increases with the functionality, and the number of devices with software defects in the field is growing. In many cases, […]

2-key mechanical USB keypad runs QMK firmware (Crowdfunding)

System76 Launch high-end customizable keyboard for PC’s that we covered earlier this week, and ANAVI Macro Pad 2 2-key mechanical USB keypad should not have anything in common, but they do to some extent. Both happen to feature backlit mechanical keys, are open-source hardware, and run the same Quantum Mechanical Keyboard Firmware (QKM) open-source firmware. ANAVI Macro Pad 2 specifications: MCU – Microchip ATtiny85 8-bit AVR microcontroller with 8 KB ISP Flash memory, 512 bytes EEPROM, 512 bytes SRAM Keys – Two Gateron Red mechanical switches with 3 mm LED backlighting and translucent keycaps Host connection – MicroUSB port Dimensions – 40×38 mm OSHWA certification – BG000077. ANAVI Technology says the key is compatible with Windows, MacOS, and GNU/Linux support, but as a USB keypad, it should probably just work with any host device supporting the USB HID class. ANAVI Macro Pad 2 is a smaller version of the earlier […]

Sonoff & Tuya smart plugs found to transmit unencrypted passwords

There are many low-cost smart plugs based on ESP8266 that provide a convenient way to control lights or home appliances with your smartphone. But cybersecurity firm A&O IT Group found vulnerabilities in ITEAD’s Sonoff S26 and Ener-J Wi-fi (Tuya) smart plugs that would allow an attacker to easily access your wireless network. The first security vulnerability is pretty common and hard to exploit since it’s only a concern during the setup. Sonoff S26 starts itself into access point mode with ITEAD-1001xxxxxx SSID, and is set up through the eWelink app with the user not needing to know the password. But with older firmware is was needed, so ITEAD still shares the default password: 12345678 in the user manual, and it can be used to connect to the smart plug by anyone. But once configured, it’s not accessible anymore as the smart plug should be in client mode connected to your […]

Why you should request open-source software for your IoT devices

PineTime open-source software Gadgetbridge

I usually think of open-source hardware and/or software are enabling skilled people to more easily fix bugs, improve on the design, get feedback from the community, etc… But in a world where IoT devices become more prevalent, there’s another reason why you should request open-source software: Long term support. What made me think about are two things. The first one if that I own WeLoop Hey 3S smartwatch, which I love and wear since March 2018. That’s quite a feat since most cheap devices I own often only last a few months or a year or so. I’m also used to the watch face and Weloop app interface. So what’s the problem exactly? WeLoop company closed on December 31, 2019, and while the app worked fine for about a year after that, recently I have been unable to login to the app to access my data and/or update settings for […]

Valetudo is a cloud-free web interface for robot vacuum cleaners

Valutedo cloud-free vacuum cleaner web interface

In my review of Kyvol Cybovac S31 LDS smart robot vacuum cleaner, I noted that app permissions meant both the map of your house and GPS coordinates may be sent to the cloud. But it was pointed out to me that earlier LDS robot vacuum cleaners from Roborock/Xiaomi were supported by Valetudo project that removes the need to connect to the cloud, and implements a mobile-friendly web interface as well as MQTT support for integration with Home Assistant or Node-RED. The project is not a custom firmware for the robots, and instead, the stock firmware is patched with Valetudo which developers describe as an “alternative App implementation + mock cloud which runs on the robot itself.” The good news is that you don’t necessarily need to teardown your vacuum cleaner to root it and install Valetudo, but it will depend on the model, and manufacturing date/firmware installed. The less good […]

Maypole MicroSD card reader comes with ESP32 for WiFi, smart storage (Crowdfunding)

Several years ago, we covered Zsun WiFi card reader a tiny USB card reader with WiFi and a battery that allowed users to access files via USB or WiFi from any device. People managed to hack the device and run OpenWrt on the little MicroSD card reader, but this required either to open the hardware and do some soldering, or use another method that could potentially brick the hardware, so not an ideal solution. But now Akshar Vastarpara has come with a similar device. Maypole is an open-source hardware MicroSD card reader powered by Espressif ESP32 processor providing both WiFi and the resources for smarter storage. It comes with an optional battery too to access files even without having to connect it to a USB port. Maypole hardware specifications: Storage – Swappable MicroSD cards up to 32GB Wireless Connectivity WiFi 2.4 GHz WiFi 4 via ESP32 WiSoC, Up to 4 […]
