Hackaday ☛ Low-Resolution Fluid Simulation On An ESP32
Fluid simulations are a key tool in fields from aerospace to motorsports and even civil engineering. They can be three-dimensional and complicated and often run on supercomputer clusters bigger than your house. However, you can also do simple two-dimensional fluid simulations on very simple hardware, as [mircemk] demonstrates.

CNX Software ☛ ESP32-C6-based Wi-Fi relay board features six 10A relays, supports Home Assistant, 3D printed enclosure
Seeed Studio’s XIAO 6-Channel Wi-Fi 5V DC Relay is a compact ESP32-C6 Wi-Fi relay board built around the XIAO ESP32C6 module which supports Wi-Fi 6, BLE 5.0, Zigbee, and Thread connectivity. Designed for remote control and automation, the device comes with pre-installed ESPHome firmware and features six independent relay channels, each supporting 10A at 30V DC or 250V AC, making it ideal for simultaneously controlling multiple DC or AC devices.

Rachel ☛ Two modems, a length of line cord, and no battery
I've been up to no good this afternoon with a pair of VIC-20s. A very long time ago, I asserted that you could connect some modems with just a length of line cord in the middle. In the time since then, various folks have done things to recreate the old days of dialup BBSes and even ISPs, and they've gone to lengths to have a line simulator in the middle, or a battery, or other strange things.

The Register UK ☛ Framework Desktop wows iFixit – even with the soldered RAM
Repair biz iFixit was on hand at the Framework launch in San Francisco, and has published its findings on the latter unit.
Acknowledging the fact that desktop PCs are already modular and upgradeable, iFixit says the Framework Desktop features tool-free panels, standard connectors, and off-the-shelf components wherever possible, making for easy disassembly and stress-free upgrades.

Jason Burk ☛ Hey, it's Jason! // Old Hi-Fi, New Trick
In this episode we add a little more functionality to the amazingly wonderful iPod Hi-Fi.
Me: Wouldn't it be neat to be able to send audio to the Hi-Fi via AirPlay 2? Also Me: Yes, it would. Me Again: Let's do that!

Arduino ☛ This three-fingered robot hand makes use of serial bus servos
A small startup called K-Scale Labs is in the process of developing an affordable, open-source humanoid robot and Mike Rigsby wanted to build a compatible hand. This three-fingered robot hand is the result, and it makes use of serial bus servos from Waveshare.

Bunnie Huang ☛ Solution, Name that Ware January 2025
After reading through the comment thread a couple of times, I find it too hard to assign any one person a clear winner. A shout-out to FETguy for the explanation of the crinkly solder mask: I think the SMOBC vs HASL answer is correct – turns out I probably knew the answer to this once upon a time, but I had forgotten it with old age. Unfortunately, there wasn’t a tie to break in the competition – I think none of the guesses got close enough for me to declare a winner, despite all the thoughtful commentary. Thanks to everyone who participated!

PC World ☛ New botnet malware infects 1.6 million Android TV devices worldwide
According to the security researchers, the new Vo1d variant — or rather the botnet based on it — protects itself with improved encryption (which prevents cybersecurity experts from sending commands to the bots and analyzing them) and improved cloaking abilities.
