So previously I have used this 24V to 5V regulator with integrated synchronous FETs from Richtek:
It is a nice part, has close to 90% efficien...

If I hypothetically had a 10 MHz reference and wanted to lock a 155.52
MHz VCXO to it, the obvious way would be to divide both down to 80 KHz
(the GCD) and drive a phase detector back into the V...

Has anyone used silicon oscillators? I'd like to stock a few SOT-23
oscillators to replace quartz crystal oscillators for non-critical
stuff. Something cheap, of course.

I've rescued a couple of Atom-based SBC's. Essentially
Am I correct in assuming these are just "yet-another-x86"?
Are there any downsides/upsides/proble...

I have some blank wall outlet cover plates, claiming to be "nylon".
Do you think I could punch a hole thru one of these with a chassis

Somewhat off topic, but maybe someone here knows a "numerically inexpensive" way to do this:
I have (x,y,z) data - about 1.6 million points. (maybe more)
The (x,y) is somewhat regular...
