Motorcycle and ATV Table Top Scanner

The Motorcycle and ATV Table Top Scanner (MATTS) is an automotive diagnostic device I created for my senior design project at the University of Florida. MATTS is a bench-top unit to which four common automotive electrical components can be 'plug-and-play' tested, displaying a result on the screen.

The four common components MATTS can diagnose are the stator, rectifier/regulator, CDI box, and ignition coil. Electrical components to be tested are plugged in using manufacturer specific adapters. Diagnostic results are displayed on the screen, and there is an onboard spark plug to live demo an ignition coil (carefully).

I began this project about a month before the semester began, working alone with the assistance of my professors. I designed two PCB boards, one for the display screen and buttons mounted under the roof of the unit, and the other the motherboard. At the center of MATTS is a PIC18F46K80 microprocessor loaded with software all written by myself in C and programmed using MPLAB. PCB layout was created using Altium, which was sent out to Advanced Circuits of Aurora, Colorado for fabrication. Hardware is mounted in a gutted and modified PC power supply housing, and uses a standard wall plug for power.

Below are images of the device, some prototype and unused PCB boards, and an example of the four automotive components that can be diagnosed.

I must search through some flash drives and computers to find schematics and Altium files and will update this post.
