Motorized Bike Ignition Systems by MBI

Welcome to the Motorized Bike Ignition Systems (MBI) repository! This open-source project aims to provide a comprehensive solution for motorized bike enthusiasts, offering a reliable and customizable ignition system.

Table of Contents

Introduction

Motorized Bike Ignition Systems (MBI) is an open-source project focused on developing high-quality ignition systems for motorized bikes. Our goal is the development of new CDI technology, tools for evaulating them, and providing open and closed source CDIs for motorized bike engines.

Features

  • Reliability: MBI ignition systems are designed for reliability, we overspec all parts and vet most of our designs before release for reliability.
  • Customization: The project seeks to make it easy to custimize and modify the open-source designs for your own engines needs.
  • Compatibility: Our ignitions are a drop in replacement for almost all stock motorized bike engines that use a standard magneto and magnet.
  • Open Source: The entire project is open source, encouraging collaboration and innovation within the motorized bike community.

Acquiring

There are a few ways you can go about acquiring a CDI. You can:

  • Order your own boards (minimum of 5), components and equipment, then build them yourself. This is the cheapest option for small batches.
  • Order your boards from an approved seller in your desired quantity, order components and equipment then build them yourself. This is cheaper for single board runs.
  • Purchase a board and component kit (COMING SOON).
  • Purchase a completed board. This is the easiest to get running out of the box.

Updates

Since this is an open-source passion project, we are adding information when we find time to. The wiki will start to get more and more information as we build more testing equipment and gather more knowledge from the community. If you think that there's more to add then consider becoming a contributor or donating to the project!

License

This project is licensed under the GPLv3 License. Feel free to use, modify, and distribute the designs in accordance with the terms outlined in the license.

Donate

If you find this information helpful then consider contributing to the project! All donations go towards contributing to this repo and developing open source devices to add.

Questions

How big is the UnoShield PCB?

It measures 68.6 × 53.3 mm and has 2 copper layers, 1.6 mm thick.

What parts does the UnoShield use?

56 parts, built around the LNK3206D-TL, 1N5231B and SA5.0A-TP. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the UnoShield KiCad files?

From the MBI-Ignitions/MBI_Ignition_Systems repository on GitHub, at the commit this page was made from: the board is Open Source CDIs/UnoShield/unoShield.kicad_pcb and its schematic Archive/Mk1/Mk1 SMD/Mk1CDIs.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the UnoShield design in my own project?

Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
