Looking for the most advanced electronics simulator in the world?
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 first to answer a consistently asked question: "Will 2.0 be free to existing users?" Yes. And let me introduce to CRUMB Advanced. To tho…
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 simulated ARM architecture for a Raspberry Pi. However that has changed and v2.0 is going to open up huge doors to infinite possibilities. Take…
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 dynamics. There will be a little break until my next update, but be sure to keep an eye out 🤩
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 jumpers has had a facelift and the wires remain fully adjustable after placement! So excited to bring this to everyone! C P.s yeah... just an…
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 implemented it at the time and I needed to go away and become a better developer before I could improve it... Thankfully that day has long…
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 all of the feedback and settled on one thing, the next version of CRUMB is to be a world leader in electronic interactivity that is true t…
Program shaders from within CRUMB Some 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 ability to create components with the same fidelity, at the very least, as the ones that I created in the 1.x versions of CRUMB. In order to…
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 members of the community, and a big thank you to those of you who have been following along with the journey toward v2.0. The patience i…
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 of your comments, good and bad and it is taken wholly into consideration for the future. Progress with v2.0 is moving along at a pace now.…
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 custom components one step closer! 2.0 will be released as a free update in the future to all existing CRUMB users
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 differences found between CRUMB and real world applications. It would be great to hear from you all and get your feedback on your findings! On…
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 work, but I think I am at the point of needing to move from a solo project and make a team. I am putting in alot of hours!
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 best Mike
I have removed support for AVX2 for the time being as it would appear that some users do not have support from their CPUs. The performance loss is negligible, if any, and should stop crashing for affected users! As always, please get in touch with any issues that you may be having All the best Mike
In the last 24 hours since 1.3 was released, a couple of errors have been noted. I have worked hard with several users to isolate the problems. I honestly cannot thank them enough for their patience. I have updated a few key areas, which should significantly improve stability and hopefully stop some users getting crashes when placing unconnected components and creating wire loops with switches.…
Better late than never... Simulation speed was always the limiting factor for the future of CRUMB. No matter how much work I put into other areas, I was always hit with the same issue and I was not able to achieve the vision that I wanted for CRUMB. Initially I had said that I had found a 2000% increase in performance with last month's development update, but that milestone has since been blown…
Hello everyone, just a quick update on progress! I am for the most part complete with the speed update, it is actually now possible to run some of the circuits at 96,000Hz which is great news... especially if you want to create circuits for audio/analog processing 😍 However, I am going through a few checks and tidy ups with everything to do with audio input as I want to compile two updates in…
Work on the first major update is going well, although I am up until 2-3am most nights working away hard! Speed is the major update to begin with, it has got to the point now that it is actually immeasurable just how fast I have managed to get the simulation running. Some circuits I have had running at nearly 200,000Hz!! Even the Ben Eater 8 bit CPU I can run at 2,000Hz with ease on my 2019 Mac…
Some of you will have already seen in the discussions that I have been made a major breakthrough in the development of CRUMB. Since before I even released CRUMB nearly 2 years ago, I have been constantly searching for more performance and speed. As a developer, I have been completely blown away by this new performance. I will give a full breakdown of changes when I release the update, which sho…
Just a quick update to show that I am pouring long hours in to making CRUMB Advanced as detailed and complex as possible 😄. Further developments include: Dockable Panels and Windows Hierarchy Browser Transform Tools Material Editor + much more! Below is a quick screen recording of the latest iteration of the component editor UI Cheers! Mike
The core concept of CRUMB 2.0 is to be able to give the user the ability to create any component, mechanical or electrical. The starting point is the importing of a 3D representation of that component. Switching to the Unity UIToolkit, I have been able to create new runtime tools to allow the user to import a variety of 3D model formats and offer material customisation. Below is video from the…
Just want to share a quick screenshot from the development build of CRUMB 2.0 showing the new Component Editor! You can import a variety of 3D model formats, define pins, tie points, all programmed functions etc... It is really going to be possible to have an infinite number of components made by the community!
Hey everyone! Long time since the last update, but I have still been working away hard between my real job and young family! I have been gathering lots of info from all the users and my whiteboard is now covered in ideas and feature requests I am not quite ready to show new screenshots/video recordings as the latest User Interface is very much in a debug/alpha phase and does not represent what…
Whilst I am taking a small break from development after the big update, I thought it would be nice to sit down with CRUMB and have a play around! I started development just over a year ago after I discovered some of the videos made by Ben Eater ( eater.net ) and wanted to create a simulator that would allow people to craft some of the amazing circuits that he has made. CRUMB has grown beyond th…
Finally the Update is here! Thank you to everyone who has been patient whilst I have been working long days and nights to re-write the vast majority of the Core UI code. CRUMB may not look too different, but underneath what you can see, it is now a very different and streamlined program. There should not be any issues with numerical entry or crashes. However should you find any other problems d…
Hey everyone! Another update for you all to show I'm still hard at work and I haven't abandoned anyone who has had problems with V1.0! The new update already has lots of features added already. Most of the work is being done to rectify this program breaking fault with differing CultureInfo across the world affecting interprocess communication and causing crashing In a nutshell, here is a little…
Quite a few users, especially those whose number systems use a different format to GB English, have been suffering breaking crashes and it has forced me to rebuild the user interface from scratch... however, a kind user on the CRUMB forum has tested a workaround for now that may be of use to some of you with problems. CRUMB Forum post Basically as a temporary measure, if you would like to use t…
