PalmOrb is software that allows you to use your PalmOS device as an LCD status display for your computer. You can display system stats (such as CPU load graphs, CPU temperatures, free disk space), news alerts, stock indexes, WinAmp graphs, etc. It works by pretending to be (or emulating) a real LCD (a Matrix Orbital LK204-25). You can use existing software that expects a Matrix Orbital display.
Slink-e tools is a package of programs and libraries to drive the Slink-e infrared remote control via its serial port from a Linux system. It features an interactive program to talk to the Slink-e and exercise its functions, an editor and learner for the IR code database, a readline-based command interface, a daemon that controls a Slink-e so that multiple other programs can interact with it, and Perl libraries for talking to the Slink-e at various levels. The package also contains complete documentation of the Slink-e device itself.
k8055 is a sample program to use the Velleman K8055 interface board on Linux. The USB K8055 interface board has 5 digital input channels, 8 digital output channels, two analogue inputs, and two analogue outputs with 8 bit resolution. This software lets you manage this board on Linux.
MatPLC is a software-based PLC (Programmable Logic Controller) for industrial automation. Ultimately, it should be possible to run a factory using this software. Currently, one should keep in mind that it is still at the testing stage, and is therefore not suitable for applications where incorrect operation would cause damage or danger.
rt_x10 is a kernel module that provides a realtime driver for the X10 "two way power line interface" device (Model TW523). X10 is a protocol for sending signals over power lines. This is useful for relatively cheap components (motion sensors, light switches, etc) that make home automation feasible for the average consumer.
Hampton Bay RF Fan Control Software includes schematics for simple circuits to connect a Hampton Bay RF remote control to a Weeder digital I/O and Analog input board, a daemon to control and monitor one or more ceiling fans using these Weeder boards, and a Misterhouse module to interface with the fan_control_daemon.
