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.

Orion O6 ITX Arm V9 board - temper your expectations

When I first heard about Radxa's Orion O6, it was being compared to Apple's M1 silicon, and the product page has extraordinary claims:

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.

Gyro is an interactive installation by Mexico City artist Correo Electrónico (Máximo Campo) that explores the relationship between movement, sound, and audience participation.

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...

Name that Ware, January 2025

The ware for January 2025 is shown below.

Thanks to brimdavis for contributing this ware! …back in the day when you would get wares that had “blue wires” in them…

One thing I wonder about this ware is…where are the ROMs? Perhaps I’ll find out soon!

Happy year of the snake!

Update Feb 12 2025

Seems to be a stumper. Lots of good analysis, but …

There’s been some mention about seeing the back side of the board; brimdavis was kind enough to provide a nice image of that:

I like how there is a dashed white line for where a blue wire should go.

Also, apparently the...

Winner, Name that Ware December 2024

The ware for December 2024 is a 2mm pitch, 64×64 LED panel purchased from Evershine Opto Limited. Their sales part number is ES-P2-I, but the silkscreen says DCHY-P2-6464-1515-VP. The seller is just the name slapped on the box; like most commodity wares, there’s likely multiple channels offering the exact same make and model. So, I’ll accept any generic that more or less matches the spec as the winner.

As a matter of the “spirit” of the competition, my goal is to encourage thoughtful analysis, rather than “first to post”, so I will tend to award more insightful or accurate answers over...

How is Deepseek R1 on a Raspberry Pi?

How is Deepseek R1 on a Raspberry Pi?

OpenAI, which is only really open about consuming all the world's energy and half a trillion of our taxpayer dollars, just got rattled to its core.

Deepseek, a new AI startup run by a Chinese hedge fund, allegedly created a new open weights model called R1 that beats OpenAI's best model in every metric.
