A more mature version of this is "CRUMB" found on steam, it costs money but it's got a lot of great features.

https://www.crumbsim.com/ Steam: 78% positive reviews out of 675. $8.99. Windows-only, though the website says “CRUMB is available for iOS and Android along side its desktop counterparts on Windows and MacOS.” https://store.steampowered.com/app/2198800/CRUMB_Circuit_Sim... No affiliation.

interesting. how does this compare with more "industrial" sims like "proteus" https://www.labcenter.com/simulation/ ?

No affiliation with any. I'm a Comp.E in consumer electronics who likes to keep a pulse on these things.

Hey man, I've seen you posting salty comments a lot recently. Are you sure you're getting a positive experience out of this forum? I spend a lot of time online and when I start posting the way you do, I find that a day or two of minimizing screen time does wonders.

It's very positive don't worry about me, if you need a safe space echo chamber feel free to ignore me!

I've been an EE for a decade and I made this exact mistake last week. It's inevitable lol

I haven't managed to design a pcb without finding an issue in the first run. Shoutout to OSHpark's prototype service. Something like 5 bucks an inch and you only have to toss out 3 if you find a fault.

Write a list of everything that you fuck up every time, check the next one against it and eventually you get a good one first hit. I had three in a row that worked out of the box in the end!

Printing the board outline and layers combined as well. And checking you used the correct footprints against actual parts helps.

Are there similar solutions without 3d view? I want to get a simulator that can show me what is going in the circuit, ideally slowed down a lot. For example I was making a dongle with resistor and capacitor which was delivering a pulse-short (i.e. removing power for a short period of time instead of delivering an impulse) and while I was able to confirm overall idea with some online simulator, dialing in capacitance…

I appreciated that smoke comes out of the battery if you short it :) Edit: I am ex EE. I will note that it's horrible using this view. It is marginally more horrible than using breadboards in reality. Schematics exist because reality tends to suck or have inconsistencies. For example TO-99 packages come in different pin orders, so 2N3904 has the opposite order to a BC547. Also breadboards tend not to have full length…

I’be been reading schematics for over 30 years, sometimes i need to draw one just to understand an idea that I have. These “real” drawings (like fritzing) hurt my head. They might be useful for the casual tinkerer but anyone who finds electronics interesting should learn the basic symbols.

You can catch it with a footprint review. List all your new footprints or old footprints assigned to new parts, and have someone else check them against the datasheets. Or if you ever have the good fortune to work with a very good layout designer, they will check things like that for you just to catch you out.

I've seen such things pass through multiple layers of review. It's the kind of thing everyone knows to look for but takes a lot of effort to catch.
