Great explanations, Doctor. Although I preferred the first one in terms of picturing what goes on inside a diode, being a musician, I found the electro-acoustic feedback analogy very cool as well.
So... haven't had time (nor money) to get the Opnext project going, but soon... very soon. Is everyone else having fun?
BTW... of course I could find this out myself, but while I'm here...
How are the shipping prices from Roithner to the states? Expensive, or not too bad? Been looking at the EU-38 for a couple months now.
Alas, poor diode. I fried him well.
