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 summary of what has been changed already and will be included in the update... which I'm still on target for in the next week or two

Changes coming in the new Update

  • Complete rework of the program structure. Everything is now contained in just one process and window. From the outside, you can see only subtle differences. On the inside it is very much a different program
  • All numerical entry fields automatically format to the locale that you have on your operating system
  • Numerical fields will highlight red when incorrect data is entered. Data will only be sent to the component when using an "Update" button
  • Major command buttons all have keyboard shortcuts, which are annotated with tooltips
  • Component rotation snapping has been disabled, so it is now possible to rotated pin based components. For example, transistors can be mounted in multiple directions
  • Viewport settings are much more clear and visible, so you can switch between voltage, current, pin and logic views. All with keyboard shortcuts
  • Various component tweaks, some todo with simulation, some todo with the descriptions and pin diagrams
  • It is now possible to view the Arduino Source files
  • Re-work of code editor workflow to make changes/errors easier to track and resolve

Bonus


The concept of CRUMB is based around a very visual portrayal of real world components and a little feature I have added in gives the ability to look at LEDS in all their glowing glory 😁 take a look below

Major update15 Sep 2026100,000 copies sold. Thank you.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 marketing, just a virtual breadboard and the hope that a few people would enjoy poking around on it. Every one of those copies came from yo…In-game event12 Sep 2026Looking 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…Community12 Aug 2026Real life == Sim LifeGood 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 Arduino R3 with the same code that’s running in the simulator 🤩 Much love! Mike
