It uses Kailh Choc V2 low-profile mechanical switches mounted on hot-swappable sockets and paired...

Ode to the AA Battery

Recently this post from @Merocle caught my eye:

I'm fixing my iFixit soldering station. I haven't used it for a long time and the battery has gone overdischarge. I hope it will come back to life. Unfortunately, there are no replacements available for sale at the moment.

Devices with built-in rechargeable batteries have been bugging me a lot lately. It's convenient to have a device you can take with you and use anywhere. And with modern Li-ion cells, battery life is remarkable.

Electronic components price and lead time increases announced across the board, and not only because of RAM

Most people already know about rapidly rising RAM prices, but I’m receiving more and more emails about price increases for a range of devices, in a way that’s reminiscent of the impact the Coronavirus/COVID-19 had in 2020 to 2022. We’ve already covered the Raspberry Pi Compute Modules price increase in October 2025, followed by the Raspberry Pi 4/5 price adjustment last December. Unsurprisingly, it’s going to spread to other companies as well. A few days ago, I received an email from SolidRun entitled “Customer Notification: Industry‑Wide Component Shortages and Price Increases”: The global semiconductor, and electronic components industry is currently...

MicroPythonOS graphical operating system delivers Android-like user experience on microcontrollers

Yesterday, I wrote about Ariel OS RTOS for microcontrollers written in Rust, but there’s another interesting open-source operating system for microcontrollers that will be covered at FOSDEM 2026: MicroPythonOS. While Ariel OS is designed for secure, memory-safe, networked IoT applications on microcontrollers, MicroPythonOS targets applications with graphical user interfaces and is heavily inspired by Android and iOS, with an appstore, an LVGL-based touchscreen and button UI with plenty of widgets, gestures and theme support, and a wifi manager, as well as over-the-air (OTA) firmware updates. You’ll probably be astonished to learn that MicroPythonOS is written in… MicroPython. It’s comprised of...
