CRUMB is an immersive interactive 3D Circuit Simulator that can be used as a learning educational tool or a prototype workspace for electronic development

CRUMB offers an easy to use and interactive introduction to electronic circuits

Fully realised in 3D, you can construct prototype circuits as you would at the workbench without the risk of terminal component failure or the hassle of ordering individual components

CRUMB comes with a great selection of components to allow you to jump straight in to creating prototype circuits

With the catalogue available, it is possible to study the workings of transistors & audio filtering, all the way to programming an EEPROM to run a basic program

For the beginner, it is possible to learn and understand the basics of interactivity, and for the enthusiast it is possible to analyse and perfect prototypes before constructing real world models

Using the built in oscilloscope and analysis views, it is possible to see clearly the interaction between components from within the wires themselves

Through community feedback and suggestion, there will be many more components and features added. For a full feature list and development schedule please visit the website
