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.
Gargoyle is an interface for small, widely available routers such as the Linksys WRT54G series and the La Fonera. It provides functionality above and beyond what the default software provides including sophisticated dynamic DNS, quality of service, and bandwidth monitoring tools. The primary goal is to provide a polished interface for these advanced tools that is at least as easy to configure as any existing firmware. This project is based on top of OpenWrt, but unlike other Web interfaces for OpenWrt it places a strong focus an usability and is meant for average users, not just power users.
Gemu is a Gnome application designed to configure sound cards based on the EMU10K1 platform from Creative Labs. Gemu is capable of adding, viewing and deleting audio routes, turning on Live Drive IR, turning on the 12db boost to the front/headphone jacks on Live cards, setting the S/PDIF frequency on Audigy cards, setting the recording source, turning on digital passthrough mode, setting to the analog or digital mode of the dual-mode jack of 5.1 cards, adding and seeing patches for sources and destinations, and controlling volume on a per-route basis or by source or destination.
Gizmo Daemon is a program for controlling your computer based on events from input devices. It has built-in support for all Linux input devices, including keyboards with special keys, joysticks, remotes, dials, and more. It lets you control applications, launch programs, change the system volume, switch desktops, and directly control Amarok. It can visualize system events (such as Amarok sound output, CPU usage, etc.) on capable devices (keyboards with LEDs, Griffin PowerMate, etc.). It also features support for LIRC and RF based remote controls, allowing it to have per-application key mappings and configurable sensitivity settings.
