AUDIN again
NOTE FEB 12, 2012: After some evidence that people were actually downloading the program, I decided to check out the setup file just to be sure everything is OK. It wasn't OK! The setup file had acquired a virus. I located the original CD and set up AUDIN on my computer, preparatory to building up a new installer. Turns out the existing version (built in 2004, mainly for XP) crashed in Win 7. I revised the C++ code, recompiled, and rebuilt the installer in MSI form.

Now it works for sure in Win 7 and Win 2000-Server. I no longer have an XP computer for testing, but if it works in 2000-Server, it should also work in XP.


==================================================================================

I'm setting up to start the next revision of my speech & hearing courseware, which will be a big change. Until now it's been a CD containing a Windows program with lots of data files. The next version will be online, consisting of a set of Flash interactive lessons feeding grades into a Moodle server. Will be a lot of work to recast the whole thing.

In preparation I've been looking again at my earlier courseware, which is public domain and freely available. The earlier item, AUDIN, has more interactive animations, so I'm hoping to refresh my memory on tricks of that particular trade.

Somewhat irritated that nobody has accessed AUDIN in the two years it's been online. It has a number of interesting features including a self-teaching breadboard approach to basic electronics. (Lesson 201 et seq.)

Let's try again with an immediate connection:

An item on WUWT references a new configuration for transistors in integrated chips. It's not really new; in fact it returns to the same geometry as the first vague image of an electric valve in the 1840s. In that notion, the gate surrounded a wire and pinched the current in the wire. (The original notion didn't work because you can't pinch the flow in a full conductor like copper with a small control voltage; I suppose a very strong static field might be able to do it, but that would defeat the point of an amplifier.)

The Intel video does a poor job of representing the gate action. I did a better job in Audin! To see it, download AudinSetup and install the program, then 'Start UnGraded' and run lesson 303.

NOTE: Because the stupid website refuses to download an MSI file for stupid "security" reasons, I had to change the file to "AUDIN-SETUP.msi.txt" for permissible download. Just rename it without the .TXT part and run the MSI to install AUDIN.
