Welcome to the magic world of Excel animation!
– All the animated models are created using plain MS Excel and VBA.
– All the Excel files and PDF tutorials can be downloaded from BLOG page.
– All the downloads on this site are FREE and there are hundreds of them.
Finding engineering work quite unchallenging lately I decided to start this blog in which to share cool ways of solving engineering problems or just interesting modeling of natural phenomena in MS Excel 2003.
I use cell formulas and VBA in order to take advantage of the ease of “programming” and the native speed of the Excel spreadsheet.
My name is George Lungu and I am the author of this blog. In my daily life I am a circuit designer.
Why bother with this blog?
1. It’s science, it’s physics, it’s electronics, mechanics, games …you name it. You could also suggest future directions of development
2. Engineering is coming back in force and it will rule again. Lots of people nowadays want to either manage or market that’s why we need more engineers.
3. It might be boring at times but it’s very useful stuff. I will give it a sugar coating by producing “live” models with at least some catchy animations and sound effects
4. You can understand most of it with just a high a school background. No computer language is necessary. A little visual basic (VBA) will be involved but you’ll learn that on-the-fly. We do search Wikipedia occasionally here but as a last resort.
5. If you follow this and begin to model your own ideas with your own methods you could build some real understanding of engineering. School is good for acquiring discipline and a background, but only you can teach yourself deep knowledge by personal experience. Learn by having fun!
6. This blog it’s just a lure. The best and most effective teacher lives inside you.
7. The most important aspect: no matter what you want to do, start by thinking and experimenting before reading or asking someone else (no matter who).
Trust me on this one, you are far smarter than you think (if you dare to use your mind).
One month of continuous pondering and experimentation will get you farther than a year of school.
Learn slowly, speed is a big spoiler. The traditional education system is built on speed and superficiality.
“External teachers” were taught one thing: compliance. And that’s what they will teach you.
Trust your “inner teacher” instead. You won’t be disappointed.
- Excel is cheap and and you can find it everywhere.
- It’s a good environment to do complex programming without being a programmer. It gives you the feel of of a bread board. A donkey could use it…
- As opposed to regular programming languages, Excel is a two-dimensional programming canvass
- Excel has decent built in graphics (I like using 2D scatter plots)
- As a 2D matrix calculator, Excel it’s wickedly fast
- Excel has decent GUI capabilities within the program itself
- Programming in Excel gives you more understanding of physical processes than “black box” type programs such as Matlab, Simulink, Octave since in Excel you build everything from basic formulas
All right, Excel, but why versions to use?
2007 is slow and bugsy. While most of the models should work in most versions, if one is serious about speed, Excel 2003 or earlier is a better choice. In terms or charting speed the new Excel is about 10 times slower than the old Excel (see a 2008 study here). By the same study, with 1023 MB of RAM, the Excel 2007 Line charts take 15 to 22 times as long to redraw as the Excel 2003. The recalculation time is also slower in the new Excel, but only by about 30% (study).
And why Microsoft?
I have to admit that for introductory scientific modeling, Excel is a great overall choice out there. Though I am not against product evolution, I decry the drop in speed (mainly charting speed) in the last versions of Excel. And by the way, while Open Office “Calc” is alright for filling taxes, it is about one order of magnitude slower than Excel for large calculations. I admire the open-source initiatives though.

really it is very good to under stand xyz coordinates in excel vba.
Dear George, how can I can make two tables of cells in scatter chart 10 rows and 50 columns.
and I want to calculate distance from one table to 2nd table both tables are away from each other 30 meter. now I want to calculate distance and want to show in chart table1 cell 1 to table2 cell10
Get back to me through Facebook messenger. I need more details.

I’m devoted to your site, your work is always inspiring for stuff on Excel+VBA .
After developing a full road design software on Excel, now I’m trying to get rid of DXF Exchange format for visualization, so doing something like an ExcelCAD. Also perfomed some FEA software, hidraulics (EpanetEx).
Also I’m in the business to get kind of a RPG maker for myself (for other visualization purposes more elevated than a RPG…). [b]I would like to know if you can repost again your “FlappyBird study”[/b]. My divagations and code for the game stuff are posted on [audeser on WordPress –> Blog –> Excel-games] (will get soon left WordPress).
Some other projects that I’m working on are published on that site. Some code exposed there, not as fixed posts but evolutionary ones (so they keep changing time to time as more code gets done).
George, I am a lecturer at a small university in Central America. Despite I am not a programmer, I found your website, blog and cases amazing, and indeed are a great example of the real “Spirit” of an Engineer.
I have recommended your blog to my students!
Keep up the good work!!!!!
Thank you Rolando, I always appreciate free advertising.
What do I have to learn in order to come up with such an engineered website design?
Suggestions are highly appreciated! Thanks!
