There's a similar product at https://wokwi.com/ (with an open source core) It's actually really useful, fast, educational. Highly recommended. I also wish someone would revitalize falstad circuit sim ( http://falstad.com/circuit/ ), which is still I think the best tool for experimentation with analog electronics. Just a little bit better interface and user friendliness and it would be amazing! A somewhat more robust…

Wokwi is an awesome tool! We're actually using wokwi's open-sourced avr simulator to power arduinos in diode. One thing wokwi doesn't do however is analog simulation so we're hoping to combine spice simulations with arduino, rpi, esp32, etc.

Indeed, mixed signal simulations would be very useful, I reckon, for people dealing with sensors and that kind of stuff. Might as well simulate it before building it. It's currently possible with falstad's open source code base as well, you just have to program inputs and outputs but it's not very ergonomical let's put it that way.

In any case, I always encourage trying to be as open as you can with the software, this encourages collaboration/cooperation (and of course is just better for everyone, in most cases!).

I think (like others here) any slightly more advanced user would be more comfortable/productive in a 2D interface most of the time. But the option of having 3D for blinkenlights is sure nice :)

(also a great accessibility for people who can't afford to buy hardware for learning and experimentation but have access to a computer)

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?

>which I'm fine with because why do we need 3D? James Cameron would like a word with you. Seriously though, 3D can show off some things that just might not be realized without it. Not sure of Fritzing's design abilities with layered PCBs, but I could imagine trying to design a layered board and forgetting how tall a component is. Seeing a component "through" the second layer could be useful

Fritzing is more like 2,5D.[0]

The competition might look ancient, but IMO, a 2D interface would be much more productive and easier to work with. This site is completely unusable for me in Firefox (it does work in Edge though).

One reason is a noncritical third-party dependency; the circuit canvas will patiently wait in line to load forever until fonts.gstatic successfully loads. Normally I wouldn't post that kind of feedback here, but there's no readily apparent way to submit feedback or bug reports at the site so here we are.

Why is it even a web site? Maybe I'm just old fashioned, but this seems slow and unusable. But more importantly, I have a hard time bringing myself to trust anything that isn't saved locally. edit: Also I feel terrible that my negative comment has any weight in this thread. I don't want to be a detractor. It's just that this is not for me. People work hard to make things and you can't please everybody. You definitely…

Yeah, so we started diode 3 months ago and in the beginning here we're focused mostly on making electronics more accessible to youth/beginners. One major advantage of web based tools is shareability and we hope to see content creators writing articles with embedded diode projects so that tutorials can include inline interactive examples. This is already common in the software world with tools like codesandbox and sta…

I would just like to say that this work is amazing.

I get what people are saying, but for people trying to dip their toes into electronics (and who maybe can’t afford the equipment just yet), this might be just the thing! I don’t mean to restrict the use cases, I just think a both/and world is just fine. And this is some excellent hacking.

I tip my mouse to you.

If your circuit is so complex that you need a breadboard planner and even an fully 3D visualization you have a big problem and you should not be breadboarding but ordering a PCB.

This seems pretty cool, esp for a newbie to know how to put down a circuit.

I use http://www.circuitlab.com and find it to be quite good for laying down parts and doing simulation including time-dependence and with parameters. Very reasonably priced IMO.

For reference, here is a circuit simulator that was ported from a 2005 project and it is 2D. It also visualizes the voltage and current as speed and density of electron packets flowing through the circuit: https://www.falstad.com/circuit/ Maybe a similar sort of visualization could be used for this project? It is neat that it can simulate arduino uno code to pulse IO, as an in-simulation workbench.

I use this a lot for quickly testing things out when I am not entirely sure what I need. It's incredibly powerful, and give you scopes so you can verify things work. It may be very old and look ancient by modern standards but it's much more usable for me. Also I don't need sonmething to simulate an Arduino, I need something to say test a op-amp summing amplifier.
