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.

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.

Hyper & Cosmic – A book where typography transcends Its linguistic roots

Hypertype takes emotion and sentiment analysis data as it’s main content. This content is given form through the organisation of typographic signs, letters and symbols. The work (and the book) attempts to draw our attention to the topic of what has been labelled affective computing and the use of AI natural language processing to infer emotional meaning.

Chinese PoE extractor teardown

I needed to power some cameras using Power over Ethernet but they only supported 12V input, so I ordered some PoE extractors from ali. Here they are for your information.

They both only support 100Mbps over 2 pairs. The wateproofing was quite annoying to remove but not impossible. It seems they both can be modified to support different input/output voltage. As you can see in the pictures, they are both using H6225K step-down regulator in a very similar design.

The circuit mostly corresponds to following schematic found on the internet:

Thank you for your attention.

The Red Line – Threshold of tolerance/action

The Red Line is a physical device that examines how we adapt to escalating crises, revealing our tendency to shift the threshold of what we consider acceptable over time. It is inspired by the concept of a "red line" — a figurative boundary that, once crossed, signifies a point of no return.

The origin and unexpected evolution of the word "mainframe"

What is the origin of the word "mainframe", referring to a large, complex computer? Most sources agree that the term is related to the frames that held early computers, but the details are vague.1 It turns out that the history is more interesting and complicated than you'd expect.

Based on my research, the earliest computer to use the term "main frame" was the IBM 701 computer (1952), which consisted of boxes called "frames." The 701 system consisted of two power frames, a power distribution frame, an electrostatic storage frame, a drum frame, tape frames, and most importantly a main frame. The IBM 701's main frame is...
