Christmas at the Hormanns






Christmas Projects
Both of us are big on Christmas. Mary likes the shopping and interior decorating, and I'm big on outside Christmas displays. In 2001, I started experimenting with animated displays that are controlled by a computer. That year I built two parallel port controls that could control 8 circuits each. These were simple to build and control, but didn't provide much growth potential.

For 2002, I started in January trying to find a design that would allow me to control many more circuits without purchasing expensive Digital I/O Boards. In February, I found Hill Robertson's design for a 320 circuit device that could be controlled by a parallel port. I spent much of the year building my own version that I should be able to use for years to come.

Some References
Planet Christmas The home of computer controlled Christmas lights! If your interested in attempting your own computer controlled display, this is the place to ask all your questions.
Computer Christmas Another good reference for computer controlled lighting, this site focuses more on custom build interfaces for controlling Christmas lights. The "how-to" database is my favorite resource.
CyberResearch Web Site If you don't feel comfortable with building your own controller, Digital I/O boards (buffered versions) can be inserted into any PCI or ISA slot and controlled via a simple DLL API interface via a custom C or Visual Basic program. The largest cards offer 192 circuits.
X-10 technology I use X10 technology to turn on and off that internal window displays. (It prevents me from having to run control wires all though the house.) See their Home Automation Catalog

Really interested in creating your own animated displays but don't have the technical know-how? If so, then check out these vendors. These sites offers both the hardware and software you need to control your lights and set them to music. Just purchased as many serial control boxes as you need and license a copy of the Software. All that will remain is plugging everything in! The software is simple enough to be used by novices but powerful enough to power the most complex displays.
Miniature Solid State Relay These components are the heart of an computer controlled lights you might build. These devices convert the 5v signal from your computer into a 120V AC power source. I've found good prices at http://www.allelectronics.com (when they have them in stock.)

The Star
The odd looking object on the right has been passed through the Hormann family for generations. Now matter which direction you look at it from, you can always see a 5 point star! Made entirely of copper and colored glass, this one of a kind decoration weighs a ton. The Star was designed and built by my great-great uncle and given to my grandfather to be hung outside their Fort Wayne home where it was placed every Christmas for many years. Upon his passing, the Star was given to my father who presented it to me in 1998.

My grandparents always hung the Star outside on the porch until the year it disappeared while my grandparents were attending church. After placing articles in the local paper explaining the family significance of the star, it mysteriously reappeared a few days later. Since that incident, the Star is now proudly displayed every Thanksgiving through New Years behind glass.
