GNU Phantom.Home is a computer controlled home automation system. The software includes a circuit diagram for building the Phantom.Home.Controller, a simple circuit board that attaches to your PC's parallel port. Using the combination of hardware/software you can control (i.e. flip on or off) nearly any 120V device. And with a little bit of electronics know-how, you can probably control nearly any device at any voltage by modifying the circuit board to meet your needs. The simple circuit included can be created and built for around $25. The modules cost around $10 (basically a heavy duty relay).
GNU Phantom.Security is a computer-controlled security system. Using the software and a simple circuit board (diagram included) that you build, you can create a good basic security system that is computer controlled. The system can use off-the-shelf security devices like motion sensors, door magnets, and fire/smoke detectors with little to moderate modification. You can have a total of 5 devices per port. And if the machine the system is running on is connected to a LAN/WAN or the Internet, you can have it send e-mail. If you have a pager or cell phone capable of receiving e-mail, then you will have around the clock intrusion/fire detection for your home or office.
jukebox-control includes a Linux driver module for an easy/dirty cheap to build DIY parallel to the Sony S-Link interface, plus Perl modules with both control-A1 (II) and control-S protocol implementations. Its actually-incomplete development state makes it interesting for developers mostly.
printerpowerd is a little Python script designed for users of older printers who want to save power when not using their printer, without manually turning it on and off. It runs, checking the printer queue directory every five seconds, turns it on when it sees a job, and turns it off after a configurable amount of idle time.
DirectFB is a thin library that provides developers with hardware graphics acceleration, input device handling and abstraction, an integrated windowing system with support for translucent windows and multiple display layers on top of the Linux framebuffer device. It is a complete hardware abstraction layer with software fallbacks for every graphics operation that is not supported by the underlying hardware.
IControl interprets signals from Creative's RM-900 remote control and the accompanying IR LiveDrive! receiver unit. It is currently capable of sending input to various programs (including XMMS, Xine, XawTV, and XScreensaver), as well as circulating window stacking order (sending windows to the background), and changing input focus. It is completely configurable, allowing the user to map any key to any action the daemon supports. Support for other remote controls is planned.
J/CoMM is an OS independent RS232 remote control. The system has a client/server architecture, has an adjustable HTML GUI, and includes drivers for cameras and beamers (e.g., EIKI LC-XM1/SM1/VM1). The server runs on the computer where the devices are connected via RS232. The client can be any computer having a Web browser, JRE, and access to the device control Web site on the server. The Web page (GUI) communicates with the server through an embedded Java applet (RMI).
Javacelot is a Java utility for communicating with an Adicon Ocelot over the serial port. It uses Keane Jarvi's RXTX utility for raw serial port I/O, Jakarta's Log4J for logging, and Ant for building. Javacelot mainly adds a friendly API for triggering and responding to X10, infrared, and other Ocelot signals. It's not an application in itself, but a tool to facilitate the creation of Java-based home automation applications, especially heavily threaded Web-based applications.
