Ian Cull over at gbmini.net has come up with a solution to an issue that has annoyed US MINI owners for a couple years now. The problem is that US spec MINIs have had the auto up feature on the windows deactiviated by default. It's remained a puzzle as to why MINI decided to do this. The most obvious thoughtis that it may have been a response to the litigation happy culture of the US. However for years BMW's available in the US have had this feature with seemingly no litigation issues.

Ian decided to create a solution of his own to deal with the issue:

I have been working (and playing) with microcontrollers for 25 years. The MINI seems to inspire its owners to take their car to the max, one way or another.
When I learned that European MINIs have auto-up windows, I wanted the same! Just like rear fog lights.

Having already investigated the design of the toggle switch panel, I was able to design a circuit which easily connected “in line” between the MINI wiring and the switches.

I started with a simple “quick and dirty” design using a high-voltage PIC chip from www.microchip.com; unfortunately this design did not work. But having started down the path, it became necessary to complete the design even though it is now much more complicated than I had originally expected.

In reality, the ability to close the windows without needing to hold the switch is an irrelevance – but the design was fun! I was also able to incorporate circuitry which can control a garage door opener, providing elegant “hidden” control for owners that need it.
