I think you're right; I imagine the reporters wouldn't be familiar with physics pedagogy and just picked up the first date they saw in the google search. I was too intimidated to t…

They do have some measurement results in figures 6 and 7. Looks like they didn't nail the center frequencies but at mmWave it's reasonable for a first attempt -- they're still miss…

The Litefury/Nitefury/Acorn design has enough I/O for an HDMI output. I've designed a little board with a buffer: https://github.com/mng2/AcornHDMI Even with the fastest speed grad…

They do mention the origin story of Macross a few paragraphs up so it seems like an odd criticism. On the other hand, it's kind of neat to see that alien technology is an outlier a…

Most serious hardware is not going to be open. I think this is mainly because hardware companies need higher margins, because working with physical things costs money. For most com…

As the OP says, FPGAs are kind of niche and devoted to specialized applications. For example there's Corundum[0] for in-network compute, kind of exotic and maybe too pricey for a h…

There's the Light Phone if you can live with e-ink. Don't know how capable the music player is though.

Calls to mind a Hilfinger quote from my CS61A experience: "Mike Clancy makes the tests; I make them harder."

I've accepted that I'm going to ignore a certain interest for months, maybe years, and then come back to it when my energy for that subject comes back. Of course this means that I …

The first thing to note is that while HDL coding may look like programming, it is not (mostly). HDLs are for describing hardware, and it takes some time for this to sink in. There …

Yeah, I never expected to feel nostalgic for cubes.

Hi, I have degrees in EE and Physics. It's good that you want to get a well-rounded education, but I think focusing on E&M and circuit design will probably pay the most dividends. …

It's indeed a pet peeve of mine when an FPGA project doesn't give example utilization, but in this case they mention iCE40UP5K and M2S025 at least.

In grad school I taught a electronics lab class where the students would burn through a bunch of HDSP-0772 every semester. I thought about coming up with a replacement, but at the …

Yes, and for example 3dfx's patents for the original Voodoo architecture expired a few years ago. But a fixed-function graphics pipeline is not terribly useful these days. Technolo…

>Ultimately it is a strategic business objective to develop entirely Libre hardware, firmware and drivers. What is the thinking behind this? Build it and they will come?

Kingston has some, I got a couple of KSM32ED8/16HD recently. They are 3200 CL22, though they probably have some room to tighten up timings.

Besides being able to pack more transistors into a given area, a smaller transistor has less gate capacitance (to first order). This means it can switch faster (smaller RC time con…

There's a product on the market that claims to absorb oxygen, called Repour. I haven't tried it since the cost per use is higher than I'd like.

I use such a product (Private Preserve) and it works pretty well. I think it is mostly CO2 and Nitrogen, with a smidge of Argon. I don't drink much wine so I have bottles in the fr…

>What do the authors mean "too complex to deploy on dedicated hardware"? It costs time and effort to translate a software function to HDL/FPGA, so it's not always worth doing. For …

The most reasonable board for hobby PCIe ( I think there are a few fundamental problems with FPGA compute offload. First is that, as niche products, FPGAs are always a node or two …

>it's almost sure to work Famous last words... >we need to build and fail a lot more You know, that actually describes the early years of fusion research. People thought it would b…

This is a pretty awesome FPGA for the price but the tool licenses are a few $K if you want to stay strictly legal. For Xilinx you can actually rent a full Vivado tool AMI on AWS, b…

I have done instrumentation work in US HEP. It is fun to do stuff nobody else (or very few) people are doing, in labs with very cool stuff, working with extremely smart people. How…
