I decided to add a PIR ( Passive InfraRed sensor, or motion detector) to this clock (and others) in an effort to prolong the life of these big beautiful tubes. So, with the help of Carl Ott, I had a small adapter card made that works great with the PIR assembly offered by PV Electronics. The PV unit is a complete package that works well and is pleasing to the eye. Our PIR adapter card will work with any Jeff Thomas NixiSat or NixiChron and simply breaks/switches the connection between the MAX771 PIN 4 and the PIC16F877 MCU PIN 4 via the HV Enable line when motion is detected. It is likely it will work with other clocks, but I have not yet tested it. It also works nicely within the NixiSat/Chron clocks standard user selectable preset wake/sleep settings and does not negate this function. The card is small enough that it can be easily mounted and tucked away nicely underneath the conventional NixiSat wooden base or even placed in the GPS compartment of that clock. You will see in the images below that I have mounted the GPS connector, the Temp connector, and the PIR connector on a common section of Euro card mounted to the underside of my Streamline NixSats-based clocks. I have also included a pic of the prototype mounted to the underside of my ‘Tribute to Jeff’ clock.
