The Atari 520ST was released in the US in July 1985, but because Atari did not provide magazines with pre-production models (like Commodore did with the Amiga), it took a while before magazine reviews appeared.
Welcome to the latest edition of my on-going series in Cray-related computational necromancy. This was another just-for-fun project. Over the many years Andras and I have been working on our Cray revival efforts, there has always been a big lag between our available software (and Andras’ amazing simulator ) and my…
As a resident member of the EEVblog Test Equipment Anonymous support group, I have picked up my fair share of old test equipment boat anchors, but my knees buckle at broken recently manufactured oscilloscopes in the sub $200 range. In this case, the Agilent / Keysight Infiniivision X-series oscilloscopes have been an…
I needed to log when a light switched on and off during the night as part of debugging an oddly behaving movement sensor. To do that I built...
CedarDB is a database system that delivers unmatched performance for transactions and analytics, from small writes to handling billions of rows. Built on cutting-edge research to power today’s tools and tomorrow’s challenges.
The hugely ambitious 'Symbolic Processing Using RISC' project from UC Berkeley
Apple II disk controller cards are weird, there are a crazy number of different types , and many are rare and expensive. Can an FPGA-based solution save the day for retro collectors? You bet! Nearly all the existing disk controllers connect the same 8-bit bus to the same 19-pin disk interface, so a universal clone is…
How to turn something as ordinary as an USB-C cable into something that a lot of nerds will want to buy.
This all started from a conversation about the RP2040 MCU, and building a simple desktop/GUI for it. I’d made a comment along the lines of “or, just run some old OS”, and it got me thinking about the original Macintosh .
I've owned Starlink Mini for about 6 months, using it for camping, backup internet, and in motion inside my car. Here is my honest review.
I've always been fond of the idea of the Raspberry Pi. An energy efficient, small, cheap but capable computer. An ideal home server. Until the Pi 4, the Pi was not that capable, and only with the relatively recent Pi 5 (fall 2023) do I feel the Pi is OK performance wise, although still hampered by SD card performance…
An interview with AMD CEO Lisa Su about her path to AMD, turning around the chip maker, the AI opportunity, and competing with Nvidia.
Let's reverse engineer a restaurant pager system I bought off the internet!
In the past months, Tesla has been offering a free, one-month trial of their full self-driving (FSD) system to all current owners. It looks like they are rolling this out in stages, because I only got mine only a few days ago.
There has been much anticipation around AMD's flagship MI300X accelerator. With unmatched raw specs, the pressing question remains: Can it outperform NVIDIA's Hopper architecture in real-world AI workloads? We have some exciting early results to share. For the past month, TensorWave and MK1 have worked closely to…
Turn your chocolate into an edible color spectrum…
The RP2040 is a microcontroller made by Raspberry Pi. Unlike their more widely known products, the RP2040 is meant to be embedded in consumer electronics. It's cheap and available in tens of thousands for immediate dispatch from your local Mouser.
Discover how Hardware Security Modules (HSMs) provide robust security solutions for managing cryptographic keys and protecting sensitive data in various industries.
Programmable NVIDIA GPUs are very inspiring to hardware geeks, proving that processors with an original, incompatible programming model can become widely used.

Introduction
What follows is the story of how I fixed not one, but two, different flawed Altera USB Blaster clone devices that never worked correctly after I bought them.
Duck Hunt is considered a classic of the Nintendo Entertainment System. But surprisingly, the concept of hunting ducks did not originate in 1984– people have...

In this article I demonstrate a software only attack that allows an operating system to set the PCRs of a discrete TPM device to arbitrary values and unseal any secret that uses a PCR based sealing policy (such as disk encryption keys used by unattended unlock TPM FDE schemes).
A little-known offshoot of the ATmega series of 8-bit microcontrollers is better, faster, and cheaper than its progenitor.
Swinging for the fencesThe term “particle accelerator” might lead most people to envision long underground tunnels stretching tens of kilometers and rooms full…
