That's been a funny thing for me. I'm not an electrical engineer, at all. My electrical knowledge is an introductory electromagnetics course I had to take in college that I've mostly forgotten, reading/watching EEVblog, other internet sources, playing around with cheap and/or old parts, reading whatever I can find, etc. I've made some retrocomputing boards ( 4 layer boards can be had for very cheap these days (JLCPCB…

As someone who works for a large silicon vendor I can tell you that even with access to those industry groups the documentation still sucks!!!!

It blew my mind that the microcontroller I'm now using has a 1000+ page datasheet.

Hey! I work on Diode w/ Austin (OP). Yeah we use a wasm-compiled version of ngSpice for the circuit simulation.

presumably melony already knew that because ngspice is mostly licensed under a 3-clause bsd license which says > Redistributions in binary form must reproduce the above copyright notice, this list of conditions and the following disclaimer in the documentation and/or other materials provided with the distribution. unless you're violating the ngspice license? or the documentation and/or other materials are just hard t…

Melony is not that pedantic and melony does not ask questions whose answers melony already know. Melony has better things to do than to hound SaaS services over alleged license violations (unlike a certain somebody).

Schematics are for understanding what a circuit does. Breadboards are for prototyping small low-speed circuits. Veroboard is for prototyping larger medium-speed circuits. Gerbers & a PCB are for production and for prototyping large or high-speed circuits. If the tool could automatically make a 3D breadboard view from a schematic, it'd be pretty neat for beginners. If the tool warned you when the normal parasitic capa…

Fritzing can kind of make breadboards from schematics, but doesn't have a 3D view... which I'm fine with because why do we need 3D?

I’m not sure how valuable it would be in this case, but 3D visualisation of PCBs is extensively used in pro circuit board design. It’s very easy to place something in 2D and not realise that something will totally clash with it. Even when you have the components all set up with heights and clearance rules, it can be things like connectors where you have something blocking it so the connector is technically clear (so passes DRC) but you can’t actually plug it in because you have a big component in the way! The next level is then importing enclosures and things to make sure things fit and can actually be assembled.

It’s interesting too that there are all sorts of mistakes that become a bit more obvious when you look at it in 3D than in the 2D view.

perhaps if melony didn't know that, it is evidence that the required credit is, in effect, not being given; that the authors of this software are, in effect, passing off the work of the ngspice contributors as their own

I recently came across a reference manual for an SoC that came in at over 24,000 pages - a new personal record. The tools for working with such large PDFs generally suck.

I'm sorry about all the negativity in the comments. What I see is something that was handcrafted with the careful touch of a craftsperson that represents your individual vision for a specific digital experience. I can tell you put a lot of time into making this. Thank you for sharing this!

Yeah, joining the clubs is burdensome. I'm lucky to be in an industry where there's enough value-add, that we just pay the piper and move on. Myself, I buy that kind of stuff pre-integrated.

I mean, it's the same for me, I'm just on the software side of the company (mostly, I'd say systems because occasionally I have to borrow the PCIe packet analyzer to figure out why something isn't working).

The electronics are a thing I do as a hobby and I try my absolute hardest to ensure work and hobby resources are kept separate. Electronics is sufficiently different from my professional role that it doesn't feel draining as a thing to do on the side. I'm not one of those "spend 8 hours programming/architecting/designing at work only to go home and spend another 6 writing code for fun" kind of people. I definitely write software and learn at home from time to time, but the motivation for doing it on the side is certainly less than it was before I turned it into a full time job. So I tend to gravitate towards things that are interesting to me but not necessarily useful to others.
