Brume 2 router review with WireGuard, OpenVPN, Tor, and Adguard Home

We started the review of GL.inet GL-MT2500A security gateway, aka Brume 2, with an unboxing and teardown, and I’ve now had time to test the router in more detail so I’ll report my experience using the router with OpenVPN and WireGuard VPN, Tor, Adguard Home, and more. In a nutshell, it’s super easy to use, unless your ISP causes troubles, which it did in this case. Brume 2 connection and initial setup I connected the WAN port of the Brume 2 router to 3BB’s modem router (3BB is an ISP in Thailand), the LAN port to my laptop, and finally the USB-C power supply (power draws is 2.3 Watts at idle). Let’s now go to the dashboard using the default IP (192.168.8.1). This will take us through the configuration wizard to select the language and set up the admin password. I was then immediately greeted by an “Upgrade Reminder” and […]

TinyLlama x86 retro computer uses the Raspberry Pi Zero 2 W as a MIDI synthesizer

The TinyLlama x86 retro computer board is designed to run DOS games on a DM&P Vortex86EX 32-bit x86 processor and integrates a MIDI synthesizer based on Raspberry Pi Zero 2 running MT32-Pi firmware. Growing up playing games on 386/486-era computers, Eivind Bohler looked for similar recent hardware to play DOS games and after discovering the 86Duino x86 Arduino-compatible board, he decided to use the SOM-128-EX module powering the board to create the TinyLlama board with a Sound Blaster Pro-compatible Crystal CS4237B sound chip and a MIDI synthesizer. TinyLlama specifications: D&MP SOM-128-EX system-on-module with Processor – DM&P Vortex86EX 32-bit x86 processor @ 60 to 500 MHz System Memory – 128MB DDR3 Storage – 8MB SPI flash Storage – MicroSD card socket Video Output – VGA up to 1024×768 @ 60 Hz using the Vortex86VGA module running off an x1 PCI-e lane Audio Crystal CS4237B all-in-one audio chip MIDI synthesizer with Raspberry Pi […]

Optimize your thermal design with code_saturne open-source CFD software

code_saturn open source CFD software heatsink

code_saturne is a free, open-source computational fluid dynamics (CFD) software developed primarily by EDF that can be useful to check and optimize the thermal design of your projects. From time to time, we come across hardware platforms that do not perform to their best due to overheating leading to CPU throttling, and over time it may also impact the lifetime of the device. I’ve heard about computational fluid dynamics (CFD) before, but I always assumed the software was prohibitively expensive and Formula 1 even has a cost cap for CFD testing. But it turns out there’s an open-source program to do just that: code_saturne. As a utility company, EDF designed the software to simulate the flows around and inside the buildings, pipes, and pumps used in power plants, but Lukas Henkel found out he could also use the free and open-source code_saturne program for analyzing the air currents caused by […]
