This is the third part of a tutorial (1, 2, self) describing the creation of an animated Pseudo Random Number Generator model as a Fibonacci type Linear Feedback Shift Register in MS Excel 2003.

This is the second part of a tutorial (1, self, 3) describing the creation of an animated Pseudo Random Number Generator model as a Fibonacci type Linear Feedback Shift Register in MS Excel 2003. This part creates a very simple table type model based on combinatorial logic rather than a sequential type based on registers.

This is the first part of a tutorial (self, 2, 3) describing the creation of an animated Pseudo Random Number Generator model as a Fibonacci type Linear Feedback Shift Register in MS Excel 2003.

This is the first section of a tutorial about the creation of a Tetris game in Excel using mainly spreadsheet formulas and very little VBA. [sociallocker][/sociallocker]

Since not everybody has Excel and more and more people are on the dumbed down new versions (2007 and 2010) I am presenting these previews to give the readers a feel of the real speed and feel of some of the models in older Excel versions (in this case 2003). This preview refers to an older model. [sociallocker][/sociallocker]

This section updates an angle formula so that the virtual glider can now perform both backward and forward loops, as well as inverted flight. [sociallocker][/sociallocker]

This section of the turorial finalizes the main dynamics calculations and implements the numerical method for approximating the glider trajectory. At this point, the model is already functional but with a crude interface. [sociallocker][/sociallocker]

This tutorial finalizes the implementation of the forces and momenta acting on the plane. It also initiates some hand testing and validation of the overall dynamics of the plane. [sociallocker][/sociallocker]

This section continues the worksheet implementation of the dynamics formulas for aerodynamic forces and momenta. [sociallocker][/sociallocker]
