The Issac LPG Computer II (ILC-II) is a self-adjusting electronic system, designed around the Renesas M16C microcontroller, to control the gas supply (LPG) of vehicles equipped with a Lambda (EGO) sensor and catalytic converter. It can be configured to require no manual adjustments and can automatically adapt to different environmental conditions and use of the [...]

Xarias is embedded car computer system, based on ATMega32 MCU and programmed using C language and compiled with gcc compiler. The project is designed to obtain different car information and display it in human-readable form. It can calculate momentary and average speed, calculate momentary and average fuel consumption, show engine RPM, calculate journey time and [...]

This digital speedometer project was built to replace unreliable analog speedometer of 1971 Datsun 1200. The circuit uses digital IC like 555 timer, 4017 CMOS decade counter, 74C14 hex schmitt trigger inverter, 4553 CMOS 3-digit BCD counter and IC6 4511 seven-segment decoder/driver. This car speedometer project is equipped with two strong magnets to the tailshaft [...]

The ODBII Code Reader is AT90CAN128-based automotive tools that can read the ODBII protocol data and tell you which car system malfunctioned; it can also clear the code, which turns off the Check Engine Light. But most importantly, the ODBII Code Reader can tell you when the computer has rechecked the systems and reset their [...]
