Diode laser FM/AM modulation
So we modulate the light from a diode laser by wiggling the diode current. This has two effects, the most obvious is that it changes the amplitude of the light. (AM) Less obvious (though I think more...

FR4 delay tempco
I measured a slab of copperclad FR4 as having a capacitance tempco around +900 PPM/degC. I wonder what would be the temperature coefficient of delay for a microstrip or stripline on FR4. Not only does...

Where to put the temperature sensor.
This is not so much a question as a report. My boss and I were talking about the above.. should the sensor go right on the plant (heater), or would it be better to move it away. I figured it would be...

OT: More spectacular downpours as global warming progress.
talks about the factors that limit spectacular downpours, and how a warmer atmosphere isn't going to limit them as strongly as it does now. We've already had had statistics on the increased frequency...
