Hey everyone!Not a new feature this time, but something I'm just as excited about... the brand new crumbsim.com is now live 😁 I've been building it alongside CRUMB Advanced so that everything is ready and waiting for release day. It's not just a pretty front …
Just a quick little preview screenshot from the development build 🤩 I will post a major update soon regarding release for 2.0. But honestly, just look at that.... A proper Scope, showing trigger edges. A Multimeter with true to life options 😁 I listened to a…
EDIT: I have re-written this post due to some interesting comments that it looked like it was written by AI. Strange time we live in, but hopefully this reads like a normal person now 😒 Good morning/afternoon/evening everyone!A massive welcome to all the new …
Fixed memory leak from the C++ MatrixMath.dll when running large complex circuits. As users are starting to build larger, the solving logic runs through a few more steps to converge and one of the steps had an overlooked leak. CRUMB 2.0 update: Still hard at w…
Slight change to the convergence code of the Diode Element as there were some unique circuit configurations unable to solve, causing a memory leak as the Math Engine tries to compensate
More fixes! 74HC245 fixed issue with the DIR pin not functioning correctly and causing a crash due to matrix error Corrected pin labels for 74HC245 and 74HC273 Fix issue with a single remaining pin label after a component delete with pin hints enabled All the …
Hey everyone! Lot's of new users and lot's of questions in the discussions! I am very hard at work on CRUMB Advanced (2.0) and it will be coming soon 😁 Not much more to say on that, except... Before anyone starts moaning, YES you will get CRUMB Advanced at re…
100,000 😮That's how many copies of CRUMB Circuit Simulator have now been sold on Steam. I keep looking at the number and it still doesn't feel real.CRUMB started as, and still is a one-person project. It went out in November 2022 with no publisher and no mark…
I have been super busy posting on Facebook with new developments and features and have neglected to keep everyone up to date here! CRUMB 2.0 is shaping up nicely and has the potential to become the single most powerful and accessible electronics simulator! But…
Good evening ladies and gentlemen!I’m continuing to pour my life into this next version of CRUMB and I have a little something to share with you all! It is now possible to connect real hardware to CRUMB and interact with it, in this example we can flash an Ard…
Just another quick update everyone! So excited for this one.I always had a vision for the original CRUMB to run DOOM, but the Arduino I simulated was not the right component, nor was there enough simulation power/optimisation to even dream about fully simulate…
Time for another CRUMB 2.0 update boys and girls!! This time a much requested feature from the last few years, mechanical/physical components! Even better, you can back feed values into the simulator to accurately simulate loading and other important circuit d…
Not just eye candy... An entirely new and revamped wiring system will make it easier to prototype and iterate quickly layouts and connections. Prototyping jumpers offers a fast way to create connections and adjust them on the fly. Wire routing with small jumpe…
Good early morning everyone! (GMT+1 😂) As always, smashing through development at all hours and have got a little something to show! The Arduino implementation in the current version of CRUMB is not up to standard. It was an architectural decision on how I im…
Program shaders from within CRUMBSome people may look at this update and ask the question "why do we need this?"... And the answer is very simple. One of the core concepts and non-negotiable features that CRUMB 2.0 needs to have, is for users to have the abili…
Good morning/afternoon/evening to everyone! First of all, welcome to all the new users of CRUMB! And a big heartfelt thank you to everyone who has been with CRUMB since the beginning and patiently waiting for the next ground-breaking update. I appreciate all o…
After the bold decision to leave Unity and switch to Godot for development, the next major iteration of CRUMB will benefit from fully native customisable docking windows and layouts. With the added benefit of built-in code editing functionality, bringing custo…
Hello everyone, Contrary to some of the recent reviews saying the project is dead, it is not... I just happen to be working on this in my absolute spare time between work, family and living! I have had a few comments, discussions and reviews highlighting diffe…
