Diode – Build, program, and simulate hardware

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 bus bars depending on vendors. At least though in this form it's an ideal representation though which doesn't have parasitic capacitors, inductors, dodgy contacts and no ground plane all over it.

It is good fun though :)

- click simulate in the default "push button to turn on LED" demo

- clock advances

- voltage around the LED slowly rises to infinity for some reason

er.

I remember following this at the time! FYI it was "shut down" (kept online but no further development) two years ago (https://x.com/KennethCassel/status/1620500575183073280)

> Decided to shutdown Diode. (For now the site is live, I'll likely open-source the code in case anyone wants to take the baton and run)

Kenneth is now working on RMFG (https://www.rmfg.com/)

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

Looks great, but pretty difficult to work with. Would be nice to be able to switch to top view to see more clearly where you're plugging things.

Not a fan. The standard schematic abstraction is great and actually helps us parse circuits.

Don't add unnecessary complexity just because AIs are good at vibecoding threejs demos (edit: even if this particular demo seems to predate vibecoding and was likely used for training instead of being the product of inference).

This is so damn cool. I remember 10-12 years ago i used to teach kids to do these things manually. This is a great product for kids to experiment and then run it real life on their kits.

I feel like the fade-in animation when starting/stopping the simulation takes too long. Also, I think it would be helpful if the currently connected row was highlighted when dragging a pin.

I'm working on a similar project, it's called schematik.io and you can use it to generate hardware projects (schematics, components lists, code, everything). Love the 3d viewer they've done here.

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 and resistance required physically switching components. Ideally I want to be able simulate such transient effects and arrive at specific numbers ready to be soldered.

And I want it to be free/open-sourse ideally :)

Years ago, around 10-12 years back, our Windows XP PC had software similar to this. Dont remember the name. I used to spend hours experimenting with it. haha Nostalgia.

I could not sign up, because "email rate limit exceeded" but i was wondering if it had a feature to probe the voltage at a certain node.

Damn the 3D graphics look great

This would be useful for opensource hardware projects (aimed at beginners) to literally see how things are wired together. I'm still not at the schematic phase myself. But I use MS Paint wiring diagrams.

OMG the wires flex, damn

This was done before, years ago, but in 2D. I forget what it was called. It was like an LT Spice clone with better UX.

the 3D look is cool but makes it harder to put stuff together

Nice! You can play Electroboom without actually getting shocked. If you do want the real world experience you can get bags full of components on Amazon for pretty cheap

Interesting if there could be automated circuit designs through it

This is really terrific!!!

Super cool. Wonder if we can input the circuit as code.

I want an AI that I throw the simulation and it design the PCB and all verification.

OK the smoke was really funny

Nice, reminds me of https://wokwi.com/ .

Black screen with "Application error: a client-side exception has occurred (see the browser console for more information)."

lacks exception catching for when webgl is disabled

wow. looks amazing

this is dope

Lol, it simulates magic smoke as well.

Holy requests, batman.

... Why so many requests for a static asset?
