GridLAB-D is a new power system simulation tool that provides valuable information to users who design and operate electric power transmission and distribution systems, and to utilities that wish to take advantage of the latest smart grid technology. It incorporates advanced modeling techniques with high-performance algorithms to deliver the latest in end-use load modeling technology integrated with three-phase unbalanced power flow, and retail market systems. Historically, the inability to effectively model and evaluate smart grid technologies has been a barrier to adoption; GridLAB-D is designed to address this problem. User documentation can be found at: http://gridlab-d.shoutwiki.com/wiki/Quick_links The source code is available from GitHub. See https://github.com/gridlab-d/gridlab-d. Issue tracking is handled by GitHub.

The Orbit Determination Toolbox (ODTBX) is developed by the Navigation & Mission Design branch at NASA Goddard Space Flight Center as an advanced mission simulation and analysis tool used for concept exploration, proposal, early design phase, and/or rapid design center environments. ODTBX functions and utilities are combined in a flexible architecture that allows for modular development of navigation algorithms and simulations. The core ODTBX functionality is realized through a set of estimation commands that incorporate Monte Carlo data simulation, linear covariance analysis, and measurement processing at a generic level.

Electronic circuit simulator. Simple environment to run and debug firmware for AVR 8-bit microprocessors. Able to run arduino firmware. Internally this program uses the open source Simavr AVR Processor Simulator (https://github.com/buserror/simavr) and wraps all its functions in a GUI shell. Setups for firmware debugging scenarios can be created dynamically. Able to run 16MHz MCU with decent set of external parts in real time. In particular this can be used for development of CNC firmware in conjuction with its CAM frontend without access to the real hardware. For Linux and Windows systems.

An Qt based HP-41cx Emulator first based on Eric's NSIM-0.61 Project. Ported to C++ and extended by an graphical Qt-based User-interface. Since Oct.2014 I developed my own NUT-Core implementation which is quite different from Eric's one. I called it NewT in fact of the existing NewT NUT Hardware revival.

Software for simulation 8051 instructions. It can translate all 255 instructions, but instructions for external memory are not implemented yet. 8051 simulator have nice GUI based on Qt where you can load your programs in assembly language, run them, step them, debug them and so... GUI shows all registers and their values you can also connect virtual LED, 7seg or button module to any port of microcontroler. It's not in english... but hey, just follow pictures

This software allows you perform six degree of freedom simulations of High Power Rocket (HPR) and model rocket flights. Parachute descent is also simulated. 3D flight trajectories are produced as well as detailed tabular flight data. Running in Monte Carlo mode allows generates multiple possible flight paths and splash down plots, indicating the probability of landing in an area.
