Leonardo Russo’s ArduinoSimulator is an open-source Arduino Simulator written in JavaScript that runs code directly in your web browser and shows the serial output and digital/analog pins status for various Arduino boards namely Arduino UNO R3, MEGA1280, MEGA2560, and NANO V3. We previously covered the Wokwi simulator for ESP32. Arduino, and Raspberry Pi RP2040 that’s a great little tool for educators to emulate circuits and run code right in a web browser, and it even supports the ESP32-P4 wireless MCU although it’s yet to be released. While the simulators are written in JavaScript and open-source, the tool itself is not, and for instance, you can’t run a self-hosted instance of Wokwi or use it offline. The ArduinoSimulator is fully open-source and runs entirely from a web browser. It’s not quite as complex and full-featured as Wokwi, as you can’t build your own circuits, but you still have an area to […]
Debian 12 and Linux upstreaming for the Qualcomm Snapdragon X Elite SoC
When Qualcomm launched the powerful 4.2 GHz Snapdragon X Elite 12-core Arm SoC for “mobile PCs” (better known as laptops), I was surprised they showed benchmarks for both Windows and Linux as in the past, the company focused on Windows only for this type of processor. But at the time we were only shown Geekbench 6.2 results in Linux, so it was not clear what was supported at the time. But a recent post by Abel Vesa, Linaro engineer, explains a fully working Debian 12 image with GPU rendering and WiFi connectivity was ready right before launch and work is now being done to upstream the code to Linux mainline. In this post, he shares the Linux upstreaming plan and provides instructions to install Debian 12 on an official Snapdragon X Elite reference design. Upstreaming will be done in two parts, starting with support for the following: Qualcomm Oryon CPUs Clocks, […]

Betavolt BV100 3V nuclear battery aims to deliver 100 microwatts for over 50 years
Btavolt BV100 is a nuclear battery that never needs to be charged and designed to output 3V/100µW (microwatts) for over 50 years for the aerospace industry, AI equipment, medical devices, MEMS systems, advanced sensors, small drones, and micro-robots. At 15x15x5mm, the 50-year nuclear battery is fairly small although 100 microwatts is not a lot of power… That’s only the first step, however, as the Chinese company plans to launch a 1W nuclear battery, and says that if (government) policies allow, nuclear batteries should eventually enable smartphones that never need to be charged and forever fly drones… How does that all work? First, as Betavolt states in its press release (in Chinese), it’s not exactly new technical as in the 1960’s, the US and the USSR used betavoltaic batteries for the space programs. But those were relatively large and heavy, operated at high temperatures, and were expensive. Wikipedia mentions that one […]
GL.iNet Flint 2 router review – Part 2: WiFi 6, 2.5GbE, WireGuard performance
In the first part of the review of the GL.iNet GL-MT6000 “Flint 2” WiFi 6 router, I had a look at the package content and the hardware design with a teardown of the router, and quickly tried it out. I’ve now had more time to play with the router focusing the review on WiFi 6 and 2.5GbE performance, and checking whether of 900 Mbps Wireguard VPN claim had any truth to it. The router also supports the Tor network to anonymously browse the web, Adguard Home to get rid of unwanted ads, and Repeater mode among other features. Those all work with the Fliont 2 router, but I won’t cover those in detail here, and invite you to check out the GL.iNet Brume 2 security gateway review for Tor and Adguard Home and the GL.iNet Beryl AX review for the repeater mode test.

How I “fixed” the display on Lichee Console 4A terminal
When I wrote a hands-on post about Lichee Console 4A RISC-V development terminal I noted the display would sometimes have strange effects or simply go black. I’ve now fixed the issue, and I was just probably unlucky since the issue must be rare, but I’ll still document it in case somebody encounters a similar problem and for fun! First, the video below shows what I would see on my terminal after using it for a few minutes. Since then, the display has gone completely dark, and all I see is the backlight, but I can still access the device through an SSH terminal. It looks like a bad connection issue, but I still contacted Sipeed and they told me it must have been the display connector. So I turned off the device and reopened the enclosure to remove and reinsert the cable for the display as shown in the photo […]
MINIX NEO Z100-0dB fanless N100 mini PC review – Part 1: Unboxing, teardown, and first boot
MINIX Z100-0dB (or MINIX NEO Z100-0dB) is a fanless mini PC powered by the popular Intel Processor N100 quad-core Alder Lake-N CPU with up to 32GB RAM, up to 512GB M.2 SSD, various USB 3.2/2.0 ports, a microSD card slot, two HDMI 2.0 ports, and a 2.5GbE RJ45 jack, as well as WiFi 6 and Bluetooth 5.2 wireless module. MINIX sent us a sample of the NEO Z100-0dB mini PC for review with 16GB DDR4-3200 RAM and a 512GB M.2 SSD preloaded with Windows 11 Pro. Since we’ve already listed the specifications in the announcement, today, we’ll go through an unboxing and a teardown before giving it a quick try booting Windows 11 Pro. We will then test the performance and features of the mini PC in detail with Windows 11 Pro and Ubuntu 22.04 (or 24.04) in the next parts of the review in several weeks. MINIX NEO […]
OpenWrt One/AP-24.XY is an upcoming router board developed by OpenWrt and Banana Pi
OpenWrt developers have started the process to develop the “OpenWrt One/AP-24.XY” router board based on MediaTek MT7981B (Filogic 820) SoC and MediaTek MT7976C dual-band WiFi 6 chipset, and designed in collaboration with Banana Pi that will also handle manufacturing and distribution of the router board. As of the OpenWrt 23.05 release, close to 1,800 routers and other devices are officially supported by the lightweight embedded Linux operating system, and many more claim to be running OpenWrt through a fork of the OS. But none of those are made by OpenWrt developers who have now decided to create their own router board in collaboration with Banana Pi since they’ve done such boards including the BPI-R4 WiFi 7 router SBC. OpenWrt One/AP-24.XY preliminary specifications: SoC – MediaTek MT7981B (Filogic 820) dual-core Cortex-A53 processor @ 1.3 GHz System Memory – 1GB DDR4 Storage 128 MB SPI NAND flash for U-boot and Linux 4 […]
