This is an upgrade from the first part in the sense that it can be adjusted to have more delay based inverters in the feedback (14).
An interactive animated demo of the gated ring oscillator in Excel 2003 based on the previous tutorial. This model stands out because of the real time schematic animation.
This is the fourth part of tutorial about making an interactive animated Excel model of a gated ring oscillator in MS Excel 2003.
In this version, the vertical joystick movement controls the incidence of both the main wing and the horizontal stabilizer (opposite variation) and the horizontal movement of the joystick controls the position of the center of mass.
This is an upgraded version of the aeroscope. Besides improving of certain aspects of the old version, this version has both the main wing and the horizontal stabilizer controlled by a virtual joystick (presented on this blog before and used extensively). The horizontal movement of the joystick controlls the angle of attack of the main wing and the vertical movement controlls the angle of attack of the horizontal stabilizer. I…
In this section, a joystick is added to the model which controlls the yaw rate and the pitch rate (not the angles!) of the stereoscopic cube. This joystick was used before in a dedicated tutorial and in the flight simulator tutorial. Its importance in future models can not be underestimated, hence I decided to cover this virtual device again. Use your 3D glasses while running the model.
This section displays the landscape on a 2D scatter chart and also upgrades the joystick chart by adding a dial behind the joystick image. This technique of using a stack of a back chart to display dial sprites and a front chart with transparent background to display various control devices, indicator needles and text will extensivly be used in this and future models.
This section finishes the macro analysis and continues with the conversion of the u-v 2D formula array into a chartable 1D array. It also adds two columns to the chartable array, a masking condition for each triangle and masked u-coordinate which will throw out of the visible portion of the chart any shape which has a minimum of one vertex behind the virtual pilot. The section also explains the phenomenon…
This section explains the spreadsheet implementation of the perspective rotation and translation formulas within the Present array and also the implementation of the 3D-2D conversion formulas within the Past array, then it goes on to presenting the VBA macros used (the Reset and JoyStick macros).
