CRUMBNot providedCircuit Simulation Software- Simulates Ben Eater's computer blueprint
  • Provides prompts for overloads and short circuits
  • Allows circuit prototyping
  • Includes component descriptions
  • Steam Workshop integration planned |

USER NEEDS

Pain Points:

  • Limited components prevent building certain circuits (e.g., amps)
  • Slow development pace due to solo developer
  • Lack of keyboard shortcuts (ESC to close menus, DEL to delete)
  • Inability to import designs into existing projects
  • Missing specific components (e.g., hall effect sensor)
  • Android version not easily found

Problems to Solve:

  • Learning how circuits work without physical components
  • Prototyping circuit designs before real-world implementation
  • Practicing Ben Eater's computer design virtually
  • Testing specific circuit ideas (e.g., trackpoint)

Potential Solutions:

  • Adding more components through updates
  • Implementing user-created parts system with Steam Workshop
  • Adding requested keyboard shortcuts (ESC, DEL)
  • Enabling design import feature
  • Developing Android version accessibility
  • Including hall effect sensor component |

GROWTH FACTORS

Effective Strategies:

  • Solo development with transparent communication about progress
  • Leveraging Steam platform for distribution and Workshop for community content

Marketing & Acquisition:

  • Showcasing milestone achievements (100k units sold)
  • Positive word-of-mouth from users recommending for tinkering/learning
  • Affordable pricing ($7-$9) lowering entry barrier

Monetization & Product:

  • Low-cost premium model (one-time purchase)
  • Strong product-market fit for electronics learners and hobbyists
  • Feature development focused on user requests (component expansion, shortcuts)

User Engagement:

  • Responsive developer interaction in comments
  • Incorporating user feedback into development roadmap
  • Planned community content sharing via Steam Workshop
  • YouTube tutorial integration for onboarding |
