## Electric Motor & Air Compressor Excel Animation – Dynamic simulation demo/preview

This is a model I made quite some years back to model the stability of an air compressor driven by an electric motor. The purpose was also to try to select the motor parameters, transmission ratios, energy loss in the flexible couple. I will make the Excel file available at a later date.Continue Reading

## How to Create a Wireframe Internal Combustion Engine 2D Animation in MS Excel – Preview

I am including a preview of our next series of tutorials about creating wireframe animations and games in MS Excel. These wireframe animation methods can be used in various engineering Excel models, as well as in scientific models and games in Excel. This training will be about creating a simple internal combustion engine 2D model in MS Excel. Join outContinue Reading

## Animated Asynchronous Electric Motor Model in MS Excel

This is an animation of an asynchronous electric motor in Microsoft Excel. You can download the model by clicking on the icon below and trying to run it. What is an electric motor and how does an electric motor work? An electric motor is part of a larger class of devices known as electric machines. In order to define anContinue Reading

## Power Management: An Animated Buck Switching Regulator Model in MS Excel 2003

This is an Excel animation and an engineering model of a Buck voltage switching regulator. Excel 2003 was used. Besides real time control of  common parameters such as switch ON resistance, load current, load capacitance, output voltage (vout), input voltage (vbat) etc, the user can also run very specialized tests in which the output current and “vbat” can be modulatedContinue Reading

## A Gated Ring Oscillator Demo – Part#2

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). This Excel animation is pretty much the same as in the first model, a virtual joystick controls the number of stages in the ring by horizontal movement and it can also control the RC delayContinue Reading

## A Gated Ring Oscillator Demo – Part#1

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 in Excel. It is controlled by a virtual joystick which is generated using a chart with a macro assigned to it. To start the model click the red dot within the joystick chart.Continue Reading

## An Interactive Gated Ring Oscillator Tutorial – part #4

This is the fourth part of tutorial about making an interactive animated Excel model of a gated ring oscillator in MS Excel 2003. This section adds a joystick to the model which smoothly adjusts the RC delay constant (vertical movement) and the number of delay stages within the ring (horizontal movement). An additional function of the joystick is to control the gatingContinue Reading

## An Interactive Gated Ring Oscillator Tutorial – part #3

This is the third part of tutorial about making an interactive animated Excel model of a gated ring oscillator in MS Excel 2003. This section deals with upgrading the model from a static table based one (with only 800 time steps) to a hybrid static-dynamic which is reasonably fast, yet it can run for an indefinite number of timeContinue Reading

## An Interactive Gated Ring Oscillator Tutorial – part #2

This is the second part of tutorial walking through the creation of an interactive animated Excel model of a gated ring oscillator in MS Excel 2003. This section is mainly concerned with the generation of the spin buttons, the macros assigned to them and the insertion of the worksheet functions modeling the NAND gate, the inverters and the delayless multiplexer. Towards the end of theContinue Reading

## An Interactive Gated Ring Oscillator Tutorial – part #1

This is the first part of tutorial explaining how to make an interactive animated Excel model of a gated ring oscillator in MS Excel 2003. Like most of the models on this site this model will run fine in newer Excel versions too. A delay based model was used for the logic gates which was previously discussed. An Interactive Ring OscillatorContinue Reading

## A Delay Based Animated Excel Model for Single-Stage Logic Gates – part#2

This is the second half of the delay based Excel model tutorial. In this part the final formulas are derived and implemented in Excel 2003. The model proves to be fast and reliable and it is actually fairly easy to create. For maintaining good speed no user defined functions have been used here. Modeling Logic Gates with Delay- Part#2 byContinue Reading

## A Delay Based Animated Excel Model for Single-Stage Logic Gates – part#1

After learning how to model ideal logic gates in MS Excel 2003 it is time to attemp to create a delay based model. This first model is just a theoretical presentation about delay, how it can be explained and how it can be modeled with a minimum amount of formulas while keeping a reasonable precision. The presentation focuses on theContinue Reading

## Introduction to Digital Electronics – a Simplified Model for Logic Gates – part#3

This is the third part of a tutorial about modeling logic gates in MS Excel 2003. This first model includes no delay or loading for the gates. This section creates user defined functions for each gate and uses these functions to upgrade the model. An auxiliary macro is created which measures the speed of the model in iterations/second. The model withContinue Reading

## Introduction to Digital Electronics – a Simplified Model for Logic Gates – part#2

This is the second part of a tutorial targeted at modeling logic gates in MS Excel 2003. The first part introduced the basic logic gates,, symbols and associated logic equations. This model includes no delay or loading for the gates. The following type of gates will are described: inverter, AND, NAND, OR, NOR, XOR (exclusive or) and XNOR. The tutorial has several partsContinue Reading

## Introduction to Digital Electronics – a Simplified Model for Logic Gates – part#1

This is the first part of a tutorial (self, 2, 3) about modeling logic gates in MS Excel 2003. This first model will include no delay or loading for the gates. The following type of gates will be described: inverter, AND, NAND, OR, NOR, XOR (exclusive or) and XNOR. The tutorial will have several parts and the last part will build upContinue Reading
