SONOFF ZBM5 Review – A 3-gang Zigbee Smart Wall Switch tested with eWeLink and Home Assistant

We will be reviewing a smart home device from SONOFF that we recently received right after the New Year, the SONOFF SwitchMan Zigbee Smart Wall (ZBM5). This is SONOFF’s first Zigbee-enabled Smart Wall Switch. In addition to functioning as a smart wall switch, it can also act as a Zigbee Router, making it easier to expand your Zigbee network at home in one shot. One of the key features of the SONOFF ZBM5 is that it can either operate in with-neutral (N) or without-neutral (N) wiring setups. Typically, in the market, we see these as separate models: one for with-neutral...

Build Box64 with Box32 for X86 emulation on RISC-V Linux

Build Box64 with Box32 for X86 emulation on RISC-V Linux

Recently I've been testing a SiFive HiFive Premier P550, and as part of that testing, I of course plugged in some AMD GPUs I had laying around.

I'll get to that testing at a later date, but one thing I enjoy in my testing is finding what 3D accelerated games and other applications can be run on alternative architectures. With the great work from Wine and Proton over the years, a great many games run out of the box on...

By means of two formulations - image and word - 'Tempo e Tempo' investigates the juxtaposition of time and weather to search for a world where many worlds are possible to fit in: a dreamlike time where past, present and future meet.

Emulating a PS5 Controller with Cynthion

https://www.youtube-nocookie.com/embed/MMZAyQuZHvs

We’ve recently published the second video in our Cynthion training series, so if you want to go deeper into exploring and experimenting with USB, this is for you. In this video, Martin explains the basics and evolution of Facedancer and demonstrates how to use Cynthion and Facedancer to emulate a PS5 controller. If you haven’t already, check out the first video- Sniffing PS5 Controller Packets with Cynthion.

Оживляем раритетное этажное табло от лифта

Приветствую всех!
Давным-давно, когда лифты были ещё релейными, на некоторые из них ставились довольно характерного вида табло на вакуумно-люминесцентных индикаторах. Обычно таковыми являлись административные лифты, однако подобные указатели можно было встретить и в некоторых жилых домах.
И вот однажды мне стало интересно: а как вообще устроены такие табло и чем там управляется этот индикатор? Самое время это узнать. Заодно запустим такой девайс и посмотрим на начинку более поздних экземпляров.

How to build Ollama to run LLMs on RISC-V Linux

How to build Ollama to run LLMs on RISC-V Linux

RISC-V is the new entrant into the SBC/low-end desktop space, and as I'm in possession of a HiFive Premier P550 motherboard, I am running it through my usual gauntlet of benchmarks—partly to see how fast it is, and partly to gauge how far along RISC-V support is in general across a wide swath of Linux software.

From my first tests on the VisionFive 2 back in 2023 to today, RISC-V has seen quite a bit of growth, fueled by economics,...

Repurposing Cisco power supplies

Sometimes you can find a good deal on used power supply from various vendors. In my case it was Cisco C3K-PWR-750WAC and RPS 2300. The problem is, that they don’t output any voltage until they are plugged into device. The question is, how to fool them into thinking they are plugged in.

The spec for the supply looks good:

And the interface is following:

You can see, there are some huge terminals which will obviously be power output and then 16 2.54mm pins where the detection will most likely happen. I was thinking how to find out which pins are responsible for the...

Rosetta – A narrative installation

Get full content RSS Feed

Rosetta is a narrative installation inspired by the ESA mission of the same name, told from the perspective of the probe itself. The text and custom graphic elaborations alternate on a vertical display whereas the soundtrack incorporates words from the story as punctuation. The entire system stays at the critical threshold of the Larsen effect, generating a sonic tension and spatialization that reflects the time and distances suggested by the tale itself.
