Infrared PIR Motion Sensor without an Arduino

Hi
I had an idea to promote a friend's tea and coffee business with a desktop rolling info page, but can't come up with a layout for the electronics without an Arduino. The reason I don't want the Arduino is that there isn't any room in the unit for it. Also, the cost of an Arduino is much too high for this project.

I wanted to put a horizontal rolling glass cylinder on a plinth and have it start turning automatically when triggered by an infrared PIR motion sensor placed on the front of the plinth. So when someone walks past it starts the continuous rotation servo motor, which in turn starts the glass cylinder rotating. This would also make the coloured LEDs light up from underneath, giving an illuminated effect. The main problem with this setup is the PIR has a signal terminal on it which triggers the servo and the LEDs to start. I expect this is why you see an Arduino being used in this configuration.

Is there a circuit diagram out there that does the above without the use of an Ardunio?

Thanks a lot.

Michael.
