Is CRUMB Circuit Simulator worth it for you?

We tell you who should skip it, too.

Play it if you…

Good fit
  • Electronics learners who want to assemble circuits in a 3D workbench
  • Hobbyists exploring components from passive parts through integrated circuits
  • Microcontroller programmers who want to edit source files and inspect circuit behaviour

Skip it if you…

Saves you a refund
  • Users seeking a tightly bounded puzzle sequence may find the open-ended circuit-building format less structured.
  • Players looking for varied activity beyond assembling, programming, measuring, and viewing circuits may find the scope narrow.
  • People without an interest in electronic components may have little use for the catalogue and measurement tools.

Our take on CRUMB Circuit Simulator

The defining detail is the virtual 3D workbench: circuits are assembled from individual electronic parts, then examined through programmable components, scope readings, and visual overlays.

What is CRUMB Circuit Simulator?

CRUMB is a realtime 3D simulator for constructing electronic circuits in a virtual workbench.

Its component catalogue includes resistors, capacitors, inductors, switches, diodes, transistors, MOSFETs, LEDs, displays, power sources, signal generators, integrated circuits, and a programmable microcontroller. Built-in examples demonstrate circuit functions. A code editor allows source files for the microcontroller to be viewed and edited, while a hex editor supports manual EEPROM value entry or circuit-based programming. The built-in scope accepts up to 4 components for examining circuit behaviour. Visualisation options display wire currents and voltages, show logic output at component pins, highlight pin labels and polarized-component anodes, and allow scene lighting to be disabled.

How CRUMB Circuit Simulator plays

01Component Catalogue
Parts include passive components, switches, semiconductors, displays, generators, integrated circuits, and a programmable microcontroller.
02Microcontroller Coding
The included editor supports viewing and changing source files written for the programmable microcontroller.
03EEPROM Editing
EEPROM values can be entered manually with a hexadecimal editor or programmed through circuit connections.
04Four-Component Scope
The built-in scope can display measurements from up to 4 selected components.
05Circuit Visualisation
Views can show wire currents and voltages, pin logic output, component polarity markers, and a dark scene mode.
