I'd CNC machine that part, which is much more expensive in-quantity than the casting option but for a handful of prototypes gets you there quickly.

You could look at ClinicalTrials.gov, you can quite easily search for completed, phase 3 trials example. https://clinicaltrials.gov/search?aggFilters=phase:3,status:...

Likely some kind of Electro-Optic Modulator. You could use their wavelength comb to separate the light and then use a Mach–Zehnder interferometer to perform On-Off-Keying as an exa…

Have you ever heard that "the market can stay irrational longer that you can stay solvent"? The thing about bubbles is, you can often easily spot them, but can't so easily say when…

As a practicing EE and naive programmer, It is pretty hard to build a simulation engine for electronics and even harder to build a performant engine. SPICE does this with huge matr…

>“But Graham,” I hear you protest, “I see these practices recommended in vendor’s datasheets all the time! Surely they can’t be wrong? They’re professionals!” >The 100nF value for …

Piggybacking onto this comment, but another reason for external pours is thermal performance. A copper pour on the surface on the PCB allows heat to convect off the board more easi…

I was not expecting a Worm reference in this thread, well done.

Link to the actual paper for those interested. https://www.nature.com/articles/s41467-024-48534-4 (Open-Access) I had wondered why they weren't doing this in simulation but didn't …

> According to police, the worker had initially suspected he had received a phishing email from the company’s UK office, as it specified the need for a secret transaction to be car…

WaveDrom also have a package for making bitfield diagrams ( https://github.com/wavedrom/bitfield ). Has anyone used both of these? I'd be interested to see how they compare.

Your search term would be "wiring harness manufacturer". I've not come across anyone in this space that would take a web order like PCB fabricators unfortunately, the demand isn't …

Thats odd, I can't see any reference to Creative Commons in my copy. The copyright rests with the Australian Defence Force Journal and is administered by Copyright Agency Ltd as fa…

Good point, from a certain perspective all programming languages are dead and we're actually historical computer-lingusts.

Jim's article pretty much confirms my assumption that Fortran isnt "dead" but is instead more of a de-facto domain-specific language. If you're a meterologist, you'll probably be u…

The claim here is that "existing hardware fuzzers are inefficient in verifying processors because they make many static decisions disregarding the design complexity and the design …

Systems Thinking goes beyond just causal loop diagrams, which are a useful tool in soft-systems modelling. Systems Thinking is more of a foundational mindstate rather than a set of…

Best comment in this thread, a lot of folks seem to be stuck on the etymology rather than the very deliberate use of special keywords in collabrative working. Sailing, Flight, Surg…

EtherCAT is built on top of IEEE 802.3 Frames, you're right that there is a special controller but those interface over MII to a standard Ethernet PHY. They don't look like valid E…

Another good exampe is the industrial space. Factory machinery used to communicate over serial type interfaces, but now theres a push to move to EtherCAT which is a determistic pro…

This is really neat! Lots of FPGAs have MAC peripherals or IP Cores but the PHY is usually an external component. There are some good reasons for that though, I'm not entirely sure…

Agreed, its a nice accessible article for beginners. I can see someone who has really only played with Arduinos and Adufruit modules looking at this and getting some inspiration to…

He's not using the Arduino Uno for anything useful, its just a test jig to check the cable works. He says at the start of the article that he needs a USB-UART converter to work wit…

EE is my day job so I may be biased towards more formal resources. Sparkfun, Adafruit, etc have some good stuff to get you off the ground and building projects almost right away. I…

Can't wait to be told to RTFM by some person on the internet because I cant get the security patches to build for an implantable pacemaker.
