Easy jumper
Overview
Easy Jumper is a university engineering project focused on simplifying the most frustrating part of electronics prototyping — cutting, stripping, and preparing wires for breadboards.
The goal was to design a machine that accepts simple user inputs (such as the number of breadboard holes or exact hole locations) and automatically calculates the required wire length, the strip lengths on each end, and then cuts and strips the wire with precision.
The CAD model demonstrates a complete electromechanical concept: multi-color spools, feed rollers, a cutting module, a dual-side stripping mechanism, and a user-friendly interface for inputting wire dimensions. Although the machine was never manufactured, it represents a full end-to-end engineering design with mechanical layouts, functional concepts, workflow logic, and feasibility research.
Key Features
- Breadboard hole-based input: User enters hole index or distance, and the system automatically calculates wire length.
- Automatic stripping logic: Determines how much insulation to remove from each side.
- Multi-color wire support: Four spool holders allow choosing common breadboard colors.
- Precision feeding system: Roller and rail design for consistent linear movement.
- Conceptual cutting & stripping mechanism: Modeled to show blade and stripping head motion.
- Clear user interface: LCD and input knob for quick selection.
- Designed for clean prototyping: Reduces clutter and human error during debugging.
Challenge
Breadboard projects often require dozens of wires in different lengths, colors, and strip sizes. Cutting and stripping them manually is slow, inconsistent, and error-prone. The challenge was to conceptualize a machine that: -Could determine wire length automatically -Cut and stripped wires reliably -Supported multiple spools -Was compact and user-friendly -Could theoretically be built from accessible components
Solution
We developed a full conceptual design including: -Mechanical architecture for feeding, cutting, and stripping -Color-coded spool system on threaded rods -Precise roller-driven feeder using stepper motors -Dual-action stripping head controlled by a linkage system -LCD interface for inputting hole distance or custom lengths -Software flow logic defining user interaction and machine behavior -Detailed CAD models showing all assemblies, tolerances, and motion paths Although never fabricated, the solution demonstrates a complete engineering thought process and an in-depth feasibility study.
