This spent thirty seconds with a spinning loading icon, switched my graphics card to the discrete graphics card, and then Firefox hard crashed to desktop. I think I prefer the 2003-era designs.

This is a tangent, but having worked with digital circuits for 40 years, the improvements in chips have made circuit construction -- even breadboarding -- vastly more forgiving than ever before. I've run 10 MHz clocks on breadboards and 100 MHz SPI bus on 2 layer boards that were not designed with extreme care. And, it's a fast precision ADC that's meeting its datasheet specs on that board. No doubt the parasitics an…
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…
> "just do yourself a favor and get the 4 layers boards so you can make ground and power planes"
In general, you should avoid power planes on 4 layer boards if you can. They tend to cause a lot of trouble with return currents when signals jump from the top layer to the bottom layer through a via. Prefer using ground planes for both inner layers and make sure you have ground return vias near every signal via.

flux founder here thanks for the plug! We are working on making our schematic editor so good...you'll never go back to paper :)
I’m realizing I didn’t give flux the credit I should have. I actually interviewed to work on it because as far as I can tell, this stuff is the future. So that aside, it doesn’t fit my workflow well today but I don’t doubt that it will, and for many people it already does. I’m glad to hear good things are coming! I’ll definitely keep checking in. Apologies for being dismissive of the hard work your team does, especia…
Thanks for the kind words…it’s a true labor of love
Also no hard feelings…I agree that we are early and that there is still a lot of work ahead of us.
Schematic UX hasn’t gotten as much love as it needs because there was so much other stuff to figure out first…we just needed something that worked in the very early days
And now we get to come back to it and make things like wiring truly great

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?
> because why do we need 3D? Teaching is much easier when the students can connect the abstract representation to something they can experience.
I don't have a ton of experience with teaching, but some (6 years various STEM stuff and 3 years math) and I have problem with this statement. It might SEEM easier at first glance, but this kind of interactive 3D/VR/whatever tools make much harder for students to climb up into more abstract levels. I found that it works much better than students can connect schematic with real (I really mean real) thing as early as possible.

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.
Evince on Linux is by far the best program I've found for reading large PDFs. It's worth the trouble to setup a VM or WSL just to run Evince if you're not natively on Linux.
Another terrific option is Okular. It actually has a setting to reduce memory usage on large PDF files by not prerendering pages that are not being viewed.

#176Pretty cool, though I would say that a breadboard is probably a worse UI for capturing circuits than whatever we had in 2003. But it is fair that e.g. LTspice has a terrible GUI. I always thought QUCS had the best UI of all the free options: https://qucs.sourceforge.net/screenshots.html Unfortunately it's not the most popular project.
If you haven't tried micro-cap, I'd recommend checking it out. It became free a few years ago when the company liquidated, and it's orders of magnitude more powerful than LTspice (and quite a bit more intuitive, but still not great). Don't expect any updates though.
Re: A circuit simulator that doesn't look like it was made in 2003
#177This looks amazing, but I wish the UI would have been a little more light-weight. I'm running on 100% CPU in Chromium on my Thinkpad X220.
Looks great, but yes, this is pretty unusable due to the high CPU usage. Also on Chromium.

It blew my mind that the microcontroller I'm now using has a 1000+ page datasheet.
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'd be so happy with a 24,000 page PDF, cause then at least you know where too look, and you can the search tool. I programme Siemens hardware and the docs I need are spread out over many tens of PDFs (of 100-1500 pages). I haven't found a proper tool than can let me search and view all this documentation properly. Best I found is ripgrep with some PDF extension to search which document I need, and then use SumatraPDF for finding the right page... ughh

Acrobat reader used to let you search all PDFs in a directory; not sure if it still lets you do that.

#180I want 2003. That's the last time anything worked. LTspice for example. Edit: worth nothing there is a native macOS port of LTspice now.
> I want 2003. That's the last time anything worked. This. NI Multisim is one of my [proprietary] favorites too.
Just wondering can Multisim integrate seamlessly with Ultiboard for circuit emulation since both of them now under NI? I know that Proteus simulator can perform the emulation to some extent.
