Nike computer - Installed in class room, not BC van. From Rolf Goerigk Left rack has the power supplies - outputs about 7 different voltages. Top panel is switches, meters, voltage warning lights. (Note: in the van installation, this rack is on the right side of the computer.) Middle two racks - operational amplifies…
A new paper describes how Google’s Cloud TPU v4 outperforms TPU v3 by 2.1x on a per-chip basis, and improves performance/Watt by 2.7x.
The solar kiln is based on the well know Virginia Tech design, adapted for my own needs and materials I could find easily on local hardware stores. Mine is a small one, with a gross storage space inside of about 1.5 m in length, 0.85 m wide and 0.65 high (~5’ x 2.75’ x 2’ ).
First, what is an ASIC? An ASIC is an Application Specific Integrated Circuit which basically means that it is an Integrated Circuit on a single piece of silicon and its use is limited to a particu…
Intel's 386 processor (1985) was an important advance in the x86 architecture, not only moving to a 32-bit processor but also switching to a...
The Pixel 8 hardware ( Tensor G3 ) supports the ARM Memory Tagging Extension (MTE) , and software support is available both in Android userspace and the Linux kernel. This feature is a powerful defense against linear buffer overflows and many types of use-after-free flaws. I’m extremely happy to see this hardware…
How SiliWiz helps you get an understanding of how semiconductors work and are manufactured
Since its launch in 1992 OpenGL® has been used extensively by software developers for PCs and workstations to create high-performance, visually compelling graphics applications.
In 2020, we initiated the Meta Training and Inference Accelerator (MTIA) family of chips to support our evolving AI workloads, starting with an inference accelerator ASIC for deep learning recommendation models (DLRMs).
Personal preference is an interesting thing. People can have a particular preference for something until they are able to experience something else. As we gain experience, our personal preference gets more finely tuned.
Homemade clone of the Dick Smith Wizzard/VTech CreatiVision game console.
Abstract : in the cover image the homebuilt TEA nitrogen laser in use at PhyscsOpenLab. The entire l
The objective for this project was to implement a UDP transmitter for use on the RP2040 that would consume zero CPU time. The system described on this webpage is implemented with 3 PIO state machines, 12 DMA channels, and 1 PWM channel. It generates an NLP, performs packet checksum calculations, and performs packet…
Introduction Part 1 and Part 2 of this series on the Apple Vision Pro (AVP) primarily covered the hardware. Over the next several articles, I plan to discuss the applications Apple (and others) sug…
Purism makes premium phones, laptops, mini PCs and servers running free software on PureOS. Purism products respect people's privacy and freedom while protecting their security.
A significant breakthrough in developing a passive radiative cooling (PRC) material has been announced by researchers at City University of Hong Kong (CityU) . The findings have just been published in the prestigious scientific journal Science titled “ Hierarchically structured passive radiative cooling ceramic with…
A couple of things I learned and one reasonable guess.
A few days ago, on a certain orange website, I came across an article about an improvised parallel printer capture device . This contains the line:
On October 13, 2023, Canon announced today the launch of the FPA-1200NZ2C nanoimprint semiconductor manufacturing equipment, which executes circuit pattern transfer, the most important semiconductor manufacturing process.

The Super Game Boy allows you to play Game Boy games on your Super Nintendo. This is an impressive feat, when you consider that the two consoles share basica...
The ad hoc group “Shortwave Modernization Coalition” petitioned the Federal Communications Commission (FCC) to allow data communications on multiple bands within the HF 2 – 25 MHz range with up to 20 KW, including in bands immediately adjacent to spectrum allocated to the Amateur Radio Service.
How PC hardware is implementing USB-C in a way that may or may not violate standards.
How does a vintage airspeed indicator work? CuriousMarc picked one up for a project, but it didn't have any documentation, so I reverse-en...
