ArduinoSimulator is an open-source Arduino Simulator that runs in your web browser

Arduino Simulator

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

Debian Snapdragon Elite X 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

BetaVolt BV100 50-year battery

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

GL.iNet Flint 2 Review

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.

iW-RainboW-G58M is a compact module based on the Intel Agilex 5 SoC FPGA series

iW-RainboW-G58M Agilex 5 Dev Kit Top View

iWave Systems, an embedded systems solutions company based in India, has announced the launch of the iW-RainboW-G58M system-on-module (SoM). The module is based on Intel’s Agilex 5 SoC FPGA E-series family, a lineup of affordable, midrange FPGAs for intelligent edge and embedded applications. The Agilex 5 E-series is optimized to deliver better performance-per-watt than its predecessors at a smaller form factor. They feature an asymmetric applications processor system comprising two Arm Cortex-A76 cores and two Cortex-A55 cores for optimized performance and power efficiency. The Arm cores in the Agilex 5 SoC FGPA family are more powerful than the Cortex-A53 cores in the Intel Agilex 7 and 9 products, but those have faster high-speed interfaces and more logic elements. The Agilex 5 SoM is suitable for development in fields like wireless communications, video/broadcast, and industrial test and measurement sectors. The last iWave module we covered, the iW-RainboW-G55M, was based on a […]

How I “fixed” the display on Lichee Console 4A terminal

How to fix Lichee Console 4A display

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 […]
