PangInput is a simple application to help you in typing characters from different languages in unicode. Three methods are available: 1) a virtual keyboard, mapping specific characters to each key on your keyboard; 2) custom character sets, which you can select by clicking on them; 3) macro sets, allowing input of complex scripts - basically mapping a latin transcription to the actual writing of characters or words.

This is an open-hardware Infrared Remote Controlled USB keyboard, without keys, implemented using a PIC micro-controller and MikroC. IRK! enables you to use your LEARNING remote control to control any system that you can plug a USB keyboard into (Windows, Linux, Mac). Great for controlling a home theatre system such as MythTV, XBMC or Media Center. No drivers are required. You can program *any* USB keyboard function (with or without Control, Alt, Shift and GUI modifiers) to a button on your infrared remote control and when you press that button IRK! will send the corresponding USB keystroke to the host computer. You can program *any* USB Consumer Device control code too...for example, Play, Pause, Mute, Volume up, Volume down, and many others.
