| My version(s) of "Soda Constructor" app |
|
|
 1998 ---> 2020
Do you remember Soda Constructor? So I do and because it was not available online anymore
I've decided to.. port what I remember from the original Soda Constructor to the new world of html JS apps. What I found the most frustrating was to find a proper name for it. Also, I was not sure what direction to take, I did many versions, spent many hours on going back and forth adding and cutting down the app to it's basic versions. I even found a few models on the internet and wrote simple importer... which worked. There were two users (cheers!) who wrote to me and gave some feedback.. The point I am in now is that I have 3 or 4 versions available online, all with different names, I even wrote part of a chapter to my simulations book (2nd edition) where I describe how to write such simulation which generated another instance of the app. I wrote blog post which became quite popular and people find the app.. So.. If you find some time to test all the versions, want to discover it again, give me some feedback, point me out which version is the best / the most useless, give me some directions, comments, ideas how to make it / remake it so that 5th version will be really useful and enjoyable, please find yourself welcome to test the following versions:
version 1 (simple app)
version 2 (most advanced, xml import, sound, etc.)
version 3 (full screen)
version 4 (small screen, tiny app with all options, codename: san jose)
version 5 - the first version available online

 Collection of physics games and apps (free!) |
Some time ago I gave two lectures about physics and computer science in my kids school (2018-02). The lecture covered simple physics experiments plus some software show and
self playing. The kids were very OK with it and - because this is hard for them to type and find internet adresses of those many scattered
web toy I made simple linking website, named it felp.pl and published. Enjoy! I would say these apps are for children at age 2-102.
Keep in mind, not all the apps here are mine - some of them I wrote by myself but to some of them I simply link there
Anyway, I will be happy to get some feedback on that and ideas what more to include here!
