Everything planned kind off, but then i got side tracked playing my new robot Qbo
My plan for auto wipe and lights and stuff is to use a PC to control it all, this pc will be hooked up to an IO board to read and trigger various parts of the MG loom.
For example the rover stalks with variable wipe have a different resistance measured on each variable step. so the IO board would read this value, pass to the computer which would do the timing and then back to the IO board to trigger a single wipe.
For more tricky stuff i've gone down the route of using BMW parts. This is because BMW have nice way of linking the majority of their electronics together , everything is linked via a serial bus with one 3 core cable running front to back hooking it all up. I've made a usb adaptor which can read and write to the BMW bus.
This sent me down the route of using this for auto wipe
Being a bmw rain sensor, However mounting it lead me deciding to also replace the rear view mirror with a BMW one, This gives me a Autodim mirror plus the light sensor for auto headlights, and a red led for the alarm.
Down side is i loose the map lights, so currently intending to retro fit this into windscreen surround some how
whilst not much done in the car, i've complete a lot of the programming for it until i found my half completed 3D printer in the loft just before xmas, so playing with that currently
