That is too difficult for me

A mass on or attached to a spring enters resonance upon being excited. Unlike a pendulum, its frequency does not depend on gravity. See http://hyperphysics.phy-astr.gsu.edu/hbase/shm2.html The accompanying program provides a simulation of such a resonance. The program is suitable for iPad and iPhone...

There may be a minor issue when setting the grinding angle on the Tormek grinder. The attached report describes the problem and two solutions. One of the solutions requires some calculations, for which a program in Smart Basic has been included. 20260720 Update: Link to Apple store corrected to US-v...

I tested the sample program from the PDF manual on page 54: 'Example of repeated FLIP usage: Sprite$="submarine 1.png" sh=SCREEN_HEIGHT() sw=SCREEN_WIDTH() movex=3 GRAPHICS OPTION SPRITE POS CENTRAL SPRITE "a" LOAD Sprite$ SPRITE "a" DELAY 0.04 SPRITE "a" AT sw/2,sh/2 SPRITE "a" dX movex SPRITE "a" ...

Sad but beautiful music.
It becomes a bit more cheerful if you increase the tempo.

Thanks for sharing.

I really don't understand anything about accelerando, diminuendo, ritardando, etc., but I think your program is a special achievement.
Hopefully Mr Kibernetik sees it as a valuable suggestion to add it to the app.

Great input function for programs. Thanks.
For now, you hold the record: A nice game problem. Initially, it was impossible to finish on time.
I had to increase the "speed" variable to 4 to get enough time.

I ran the program for two days. It's remarkable that after a few hours, the interval remains almost constant at two hours.

Nice game, but it gets a bit boring towards the end.
You might want to add more disasters or costs for the inhabitants of the growing community.

I also discovered a small mistake.
After 15 rounds (years) I received the evaluation and the invitation for the 11th year.

For those who, like me, are musical illiterates, I added some notes that I collected during a musical project for SB. See subchapter 9.4 Some notes on notes on page 64. The version date 20250628 is on the cover page at the bottom right corner. The PDF-manual is in size A5, which fits perfectly on iP...
