Easy way to use the 1-wire sensors like temperature, voltage and more.
OWFS -- 1-Wire file system. Use the Dallas 1-Wire and iButton chips with standard filesystem commands. Create temperature loggers. Monitor everything. OWHTTPD -- same system, only used as a light weight web server. OWFS is also ported to embedded routers, Mac OSX and Windows. Basically you can use these inexpensive little sensors and other chips with very simple wiring to sense and control the physical environment. The interface is very flexible -- everything from a web browser, to read and writing directly to the chip's "file" to integrating with your programs -- even over the internet. There is a growing number of 1-wire sensors: temperature, voltage, humidity, light, ultraviolet, pressure, thermisters, thermocouples, programmable microcontrollers, relays, lights, LCD panels, etc.

Homer is a free cross-platform SIP softphone with video support. The Homer software is able to communicate in peer-to-peer mode without any infra- structure. But it also supports SIP servers (PBX boxes) as well. The amount of participants per live video conferences is not limited by the software. Besides the conference functions, Homer can also be used for video/audio streaming, recording and screencasting. Video as well as audio data from files or hardware devices can be streamed to every conference participant individually. Additionally, video/audio streams can be started as separate unicast transmissions to any host in the local network or the Internet with quality settings ranging from very low to very high (HDTV). Such streams can be received by Homer and can again be recorded to disc and made available for offline playback. Source code: https://github.com/Homer-Conferencing/Homer-Conferencing
