Hi,
I was just wondering if it wouldn't be nice to have a wind simulator with
Indycar racing. That would surely enhance the sense of speed.
This is what I came up with:
Just use a plain ventilator. Connect a simple 8-bit D/A-converter ( or
make one with resistors ) to the parallelport. The D/A-converter produces a
voltage between 0 and 5V DC. Use a transistor to switch the current to the
ventilator.
The only problem that remains is getting your current speed as a 8-bit
number on the parallelport. I came up with the following sollution.
Make a TSR that uses ( for example ) the same interrupt as the mouse does.
In this TSR you get several bytes from the video memory. The speed is shown
on the screen in ( digital ) numbers. Those numbers consist out of a number
of segments that can be black ( on ) or grey ( off ). Reading the
colorvalues on positions within the segments could reveal the current speed.
The only thing is that in real life the drivers wear helmets, so they
problably experience wind in a different way.
Just a fantasy ;-)

Oh man,
haven't you got anything better to do than fantasising about things you'll
never get. How do get such a silly idea, I guess you even haven't invented
the idea by yourself. Probably it's the idea of a 'huisgenoot'.
Get alive.
