Which One Should I Use, Part X

Noise and Filtering, So Let's Look at Filters.

Home Control Assistant

"And since scheduling depends on your computer clock, HCA can be set to automatically update by calling a time service and downloading the correct time to your PC clock. Now that's cool. I wish my VCR, stove, coffee maker, wall clock etc. could do the same. Sometimes I can walk around my house and think that I live in several time zones at once."

Home THX- The Best of the Best

"THX stands for Tom Holman's eXperiment. If you are a fan of George Lucas, you might recognize 'THX'; it is part of the name of Lucas' first feature length film, named THX 1138."

Infrared Remote Control from your PC

"URC lets your home PC reach out and control many common appliances in your home - your CD player, TV, VCR, DSS, DVD, stereo preamp, radio tuner, cassette player, or anything else which accepts infrared remote control signals. I've given a very simple illustration in this column: pausing and muting everything when the phone rings. There are many other cool applications you can create."

Some Common X-10 Questions and Answers

"I'm a small security dealer and I'm interested in getting into the Home Automation business. I've heard that these days many customers expect Home Automation to be part of a security system. I've noticed that X-10 seems to be the DeFacto standard when it comes to Home Automation but I'm wondering how I can find out more about the subject in general."

Noise and Filtering, but let's just define noise first.

Case Study Interview

"The company has an astounding 100 million US installed base of home automation systems. This includes both modules, such as plug-in lamp or appliance modules that turn off the lights, and controllers, which turn something on via remote control, timer, telephone, computer, etc. Dave Rye estimates that about 5 million homes have X-10 modules."

CHAC & Homation

"HomAtion cleverly allows anything to trigger anything else. You can have events trigger scenes, scenes create events, events cause events, etc. You can create variables to pass data from one scene to another. You create a scene the same way you add a device, except you attach events to it."

International HA

"Even though progress on international standards is relatively slow, participation is important for the exchange of ideas among home automation developers world-wide. The specification of application models may promote product interoperability. This may be more worthwhile than the current focus on protocols, which is encouraging protocol competition."

Marantz RC2000 MKII

http://www.marantzamerica.com/rc-2000.htm "Beyond the obvious multitude of buttons allowing control of every device you own, there are 4 macro buttons situated beside the LCD display. These can be programmed with up to 20 steps each. For example, you can program one button to turn on the TV, turn on the VCR, Change to channel 6, Set the amp to surround sound and take out the dog."

Primer on CEBus's Common Application Language (CAL)

"Now that you have this home network defined, take a moment to realize that your iron, security system, garage-door opener, front porch light, ceiling fan, television and master bedroom alarm clock radio can now freely pass information back and forth amongst themselves. Part of our challenge is to identify what (if anything) one of these devices might want to 'say' to the others and why the others would care to 'listen'."

Sweet Automated Dreams

"Another remote control in the bedroom is built into a custom console mounted on the under side of the headboard. The entire console is illuminated with glowing LEDs for use in the dark. In addition to the X-10 control, there is a clock, security control panel, and an indoor/outdoor thermometer."

Too Many Remotes

"When you are entertaining or just watching a movie by yourself on a Saturday night, you don't want to be fiddling around will all of these remotes. If you do not do something about this, your couch will have a wonderful display of large, and usually complex remotes for which you need an engineering degree from MIT to use. Don't worry, there are some solutions. "

Troubleshooting Three-Way and Four-Way Switch Circuits

(DVD) Digital Versatile Disc

"In the future, DVD will offer the viewer multiple camera shots so you can view a scene from different angles and levels. DVD's will be recordable, rewritable, and reusable ... a big plus for the computer industry"
