  • Raspberry Pi Weekly Issue #516 - We come bearing three new things created by three wise Pi people

    Really struggled to think of a good footer emoji this week – please extend me a break Howdy, This week, we were delighted to introduce Raspberry Pi Imager 2.0: a complete reimagining of the application that's been brewing in our development pot for the past year. Roughly one gazillion of you left comments and asked follow-up questions, which our engineer Tom continues to answer as fast as he can.

  • CNX Software ☛ Mongoose Wizard builds professional embedded device dashboards for microcontrollers like ESP32, STM32, NXP, RPi and others (Sponsored)

    Cesanta Software introduced Mongoose Wizard – a no-code visual tool that enables embedded developers to effortlessly build a professionally looking device dashboard (WebUI) and REST API without writing any frontend code, transforming the microcontroller (MCU) board into a browser-accessible web dashboard for control, monitoring, and updates. Whether for prototyping or building production devices, integrating a web dashboard into firmware gives end users intuitive and powerful control.

  • CNX Software ☛ NetCube Systems Nagami Allwinner T113-S3 mini PCIe SoM features ESP32 wireless SoC, supports mainline Linux

    NetCube Systems Nagami is a small Allwinner T113-S3 system-on-module that I just saw added to GNU/Linux 6.18. Besides mainline GNU/Linux support, the Allwinner SoM offers somewhat unique or unusual features that include a mini PCIe form factor and an ESP32 co-processor for WiFi 4 and Bluetooth connectivity. The Nagami also comes with 128MB DDR3 embedded in the T113-S3, 4GB eMMC flash, a Fast Ethernet PHY, and a Qwiic connector for I2C expansion modules. All I/Os are exposed through a standard mini PCIe edge connector: audio I/Os, Ethernet, USB 2.0 OTG/host, and a range of low-speed I/Os.

    [Slant 3D] has a useful video explaining some thoughtful CAD techniques for designing 3D printed pins that don’t break and the concepts can be extended to similar features.

  • Mere Civilian ☛ Android: Dual-SIM experience

    Personally, despite each annoyance not being a deal breaker, when combining all of it, I am more inclined to go back to my two-phone lifestyle. It gives me peace of mind that this one-phone dual sim setup does not. However, I am curious how well the dual sim setup works with the iPhone, but I do not have the energy to undertake this experiment this side of Christmas. I will give it a go though, because carrying one phone is easier than carrying two. One cannot fight physics.

  • University of Toronto ☛ Discovering that my smartphone had infiltrated my life

    While I have a smartphone, I think of myself as not particularly using it all that much. I got a smartphone quite late, it spends a lot of its life merely sitting there (not even necessarily in the same room as me, especially at home), and while I installed various apps (such as a SSH client) I rarely use them; they're mostly for weird emergencies. Then I suddenly couldn't use my current smartphone any more and all sorts of things came out of the woodwork, both things I sort of knew about but hadn't realized how much they'd affect me and things that I didn't even think about until I had a dead phone.

  • University of Toronto ☛ Password fields should usually have an option to show the text

    I recently had to abruptly replace my smartphone, and because of how it happened I couldn't directly transfer data from the old phone to the new one; instead, I had to have the new phone restore itself from a cloud backup of the old phone (made on an OS version several years older than the new phone's OS). In the process, a number of passwords and other secrets fell off and I had to re-enter them. As I mentioned on the Fediverse, this didn't always go well: [...]
