First of all many thanx to G. Richter and R. Schmitz and all the others
I can not remember just now for interesting contributions to the list
in this respect.

We all have our favourite components for sdiy.  It takes a long time to
see all the different schematics and to see all those nice components.
Therefore I've started a little list of devices mentioned on sdiy,
necessarily incomplete.  Maybe you want to add your favourite device or
application, or comments about measurement data, or experiences etc. Or
explain some components I obviously know nothing about.

The list is by no means complete or 100% correct. 

Some help would be nice!
