CRUMB offers an easy-to-use and interactive introduction to electronic circuitry
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 into 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 the interaction between components from within the wires themselves
