Welcome back to the second part of this series on building a DIY alarm system circuit. In the previous article, I explored the various components that make up this robust security solution, including the LTE module, USB-C charging circuit, SIM card, rechargeable Li-ion batteries, microcontroller, and siren. These components work…

Do you hate it when someone steals from you? Personally, I find it rather irritating. However, there have been instances of thieves visiting our apartment building’s underground garage. And thieves do what they do, so things go missing from storage rooms. As a result, I decided to design a door-mounted…

Designing a user interface for a digital instrument cluster can be a challenging task, but it is essential to provide a user-friendly and intuitive interface that will allow riders to access all the relevant information. In the first blog post, we looked at the electrical connections in the original motorcycle…

Welcome back! In our first blog post, we took a deep dive into the pinout of the original instrument cluster connector. We explored each pin and its corresponding function, gaining valuable insights that will help us as we move forward with our project to create a digital instrument cluster. If…

For many motorcycle riders, the instrument cluster is the heart of their machine. It’s where they can easily check their speed, fuel level, and other vital information while on the road. My motorcycle instrument cluster stopped working a while back, and I had to replace it with a cheap Chinese…

A RF attenuator is a device that reduces the power of the signal that passes through it. It is connected in series with the signal source and load. A passive attenuator is a completely passive resistive network with no power source. This device may be utilized in a number of…
