Hardware-optimised library for Area correlation algorithm

"DSO" is a Digital Signal Oscilloscope. My DSO will be connected via the USB to the PC. All software to operate the DSO is developed within this project.

daitrix is a secure os built on security, ease of use, and linux/unix based. verry fast to install with 4 setup types- dev, server, desktop and all. everything a normal linux distro has and then some.

DioXygene is a project of a new calculator using a motorola processor. It will have a multitasking operating system and a support of RPL, C and ASM language directly on calc.

Engineering Calculator Suite

GXSM -- Gnome X Scanning Microscopy: A multi-channel image and vector-probe data acquisition and visualization system designed for SPM techniques (STM,AFM..), but also SPA-LEED/LEED/LEEM data analysis. A plug-in interface allows any user add-on data-processing and special hardware and instrument support. Latest: NC-AFM and related explorative methods as SQDM can be configured. High-Speed external PAC-PLL hardware option with digital DSP link. Based on several hardware options it supports a commercially available DSP hardware and provided also Open Source Code for all the low level signal processing tasks and instrument controls in a most flexible and adaptable manner. All latest software is available via SVN only or Live Demo/Install CD: http://www.ventiotec.de/linux/GXSM-Linux.iso

GlaßOS is a complete replacement OS for the TI8x calculator family. The OS is written primarily in C. THIS PROJECT HAS BEEN ABANDONED

Iterate function viewer for Windows and Linux. It has built in 14 different iterate {Mandelbrot) functions. Many possibilities for changing parameters, saving as bitmap or small file. windows-32. Linux 32 - 64bit. Low level written in assembler.

Exploring the possibilities of doing an Operating System completely different than all of the existing ones. Instead of basing it upon concepts that are 40 years old, design it from the ground up object oriented, peer-to-peer, and for security.

A set of reusable libraries and programs for the Apple Newton MessagePad, including XML/HTML parsers, an HTTP library and RSS/HTML viewers as well as GTD and organizer packages.

The purpose of this project is to create a graphically pleasing alternative to the calculator that comes default with X11.

PyramidWorkshop is an image-compression System based upon the scientific work of John Robinson (inventor of BTPC) about image-compression with adaptive linear predictors and is in average more efficient than PNG/JPEG2000.

Microcontroller (AVR) based standalone digital light controllers ("dimmers"). The "Diamond" series supports 20 channels (TRIAC, FET, 0-10V, relay) with automatic fading, 20 scenes, 21 timers, IR remote, LCD, DMX-512 interface, global standby & more.

An English, German, Japanese, Portuguese, Russian, Chinese, Hindi & Bengali desktop OS loading from miniCD or USB key with applications and personal config files on floppy or USB key.

POSIX API for Win2K-XP. Mainly implemented in the driver. Included: write-on-copy fork, threads, mutexes, spins, condvars, rwlocks, signals ... Signals/cancelation interrupt all waitable syscalls, NT syscalls are automaticaly restarted.

Android[tm] SDK development is for those who have a dream mobile device in mind and have the potential to contribute to the development of the same at various levels. http://www.openhandsetalliance.com is promoted by Google & other industry giants.

We are going to make a multipurpose librairy for the Texas instrument 68k calculator (TI-89 & TI-92+) We are planning to add optimized graphic routine, and a lot more... Grayscale graphic will be added too, of course :)
