Depends on what you're wanting to do. The OSS toolchains have matured a lot since then, with parts from Lattice being fairly well supported if you don't want to touch a vendor's tooling. Gowin have some of the more interestin

It's computer vision focused and might have been suggested previously, but I think Halide is a pretty good/mature demonstration of one way to approach this - writing the algorithm and the execution descriptions as separate passes

Agreed. Tooling like this also needs far more careful structuring of the inputs than a thin wrapper like this. It burnt a bunch of tokens and filled the context reading all datasheet files, whereas documentation should be queried to answer

I'm your target market - averaging a few dozen board designs a year with complexity ranging from simple interposers to designs at density limits with large US+ FPGAs. I'm always looking for workflow and automation improvements and

Enjoyed the paper, thanks. While there was brief discussion about environmental influence due to temperature and environmental EMI, it would be nice to get an idea of how this approach compares with regards to radiated emissions. Fast edges

Mostly used for biological targets, laser induced ultrasound is pretty impressive.

For two DRP (dual role) devices connected to each other, I believe in a default case the one that happens to advertise as a source first just becomes one. The standard allows for a role swap at any point while connected, and if that’s trigg

There’s a lot more to it, but I attribute a lot of ‘better in some way’ to microcontrast followed by how the lens handles the transition to out of focus detail.

Yep, variations have popped up in the DIY community over the years. Slightly modifying/abusing the cheap DLP resin printers is more effective because they're essentially a controllable UV mask anyway.

This is all fairly normal in robotics, under a subset of (slightly overloaded naming sorry) “impedance control”

You might enjoy https://github.com/scottbez1/smartknob The complexity of this approach (ignoring the display and flair) unfortunately means you won’t see this used too often due to cost.

Their single board computers intended for robotics/edge have had a history of being poorly supported and stuck on old kernel versions.

It’s less torturous with other brands of 2D printer. Both my Brother laser and label printer have worked first time, every time with Linux, Windows and iOS AirPrint.

Some people have different views on what’s an embedded system, but hardware serial, USB and Ethernet are tablestakes for interfacing with any most industrial hardware or for robotics uses.

For some/smaller parts. Once you start going higher than Artix or the token Kintex parts you need to pay up.

You just buy the microcontrollers and put them on your custom PCB. The devkits aren’t suitable for resale but there’s no additional licence when you buy an ARM micro from pretty much any manufacturer.

Just tacking some detail onto "promote open science". CERN was/is a large early user and supporter of the open source KiCAD electronics CAD tooling. The downstream impact of improved accessibility to solid ECAD tooling has be

As CAD tools go SW is on the lower end of the scale. Though the price increases have been feeling pretty abusive in the recent years. Creo has come down relative to it's ProE days and is priced similarly to SW(?), and I believe NX stil

While it’s probably not perfect for everyone, I know hyprland exposes the events you’d need for this, accessible via IPC.

I’ve been bitten before but the risk/reward is probably worth it for parts like that. Thanks for your write-ups btw, been following glScope development for a while.

That's low-end Zynq and Artix and I'm thinking more >676 Kintex, though I appreciate any discussion on sourcing. In the way that that Aliexpress vendor lists the 7010 parts at 1/10th the price of LCSC, some of their $20-60

Will do. Not too worried about trying low cost parts to gain some minimal confidence in a possible source, they're compelling for weekend side-projects at least. I've previously struggled to roll the dice for higher end parts as t

I was interested to see, or at least what state they're in so I grabbed a couple. Might try to compare them against some genuine ones with CT and destructive inspection. On the chance they're half reasonable, thanks for the link.

Bigger number better, obviously! I am also annoyed by most modern tech marketing using percentages incorrectly and inconsistently. But 150% is a bigger number than 1.5x so I suppose their hands are tied.

Great writeup. Always a treat to see more high quality FPGA project postmortems, even if they aren’t using accessible parts/toolchains.

I only dabble with recreationally reverse engineering industrial/consumer grade HW and following blogs/conferences, so I can only provide a rough shotgun of search terms to try and hit something you're interested in: - The Gl

Reasonably experienced and 'a week' can mean vastly different things... It's certainly easier to keep the cost down with longer time-frames. For a focus on electronics rather than implementing some kind of toy 'algorithm
