I've started a new project to design a improved clock that looks a little bit more modern and has more functions. The idea is to make a replacement PCB that fits inside the standard plastics so it will look like an OEM.
The main features will be:
* 7 segment display in one of 4 colours (white, red, green or blue)
* Clock and date, accurate to within 2 minutes per year, automatically adjustment for british summer time/daylight savings.
* Wideband lambda display
* Boost gauge, with peak hold display
* Voltage meter
* External Air temperature (possible)
The clock will also have a Canbus interface for future expansion to connect up to other data sources (OBD1/2, accelerometers, etc...)
So far I've selected a suitable LED display and I'm in process of designing the PCB. The software will be release as open source to allow anyone to customise the functionality.
