Keyless Motorcycle Ignition System
This system is truly a game-changer if you ride a motorcycle. Essentially, this device allows you to replace your physical keys, enabling you to start your bike wirelessly using a tag. In my case, I embedded the tag in a ring, which simplifies things even further. I've uploaded a video (see below) where I explain the working principles of the system in more detail. You can find the files on GitHub and the link to the complete documentation here.
Don't forget check out the follow-up to this project which is all about making the rings. This project involves several steps, so please watch the videos and read the documentation. With that said, here's a quick overview of the project:
As you can see in the diagram above, the system consists of the main board, housing the ATmega328P microcontroller and other components for interaction with the rest of the system. Next, we have the light scanner board, which contains a simple circuit to control a light bar, providing users with visual cues about the system's status. Additionally, there are two reed switches and a relay to bypass the ignition circuit. Below, you can observe how the system was installed on my motorcycle
As I mentioned earlier, the core of the entire system is the ATmega328P microcontroller, and the board was designed with a focus on reducing electrical noise and ensuring reliability under automotive conditions. This includes resilience to factors like load dumps and high temperatures.
The same design process was applied to the light scanner board, and it proved to be very reliable. However, it is not critical for the proper functioning of the system; it serves purely for visualization purposes. As depicted below, I installed it on my speedometer, and it indeed adds a nice touch to the motorcycle.
Finally, to house the system, I designed the enclosures using Fusion360 and then 3D printed them. The system operated successfully on my bike for several months. However, I had to sell my bike along with the system back in 2022. I can attest that the system proved to be highly reliable. If you have any questions, please feel free to post a comment on the videos.
