Just Milling About…
Antennas! I have spent the last few days learning to use our milling machine, practicing on cheap substrate, fixing the alignment here and there…but I think I have the hang of it now.

Mark Your Calender…

Imagine there being 20 people for everyone currently alive
…and you would have a population equal to all humans who have ever lived throughout history.

Skymap iMAT antenna
EDIT: The pcitures were huge and were getting cutoff, so I resized them quickly only to make them look really bad, and hard to read, so instead now they are thumbnails — click on them to see full size images.
