Poof!
...and it's gone.
Good news: reported was finished and handed in on time (but no comment on the quality) :P
Bad news: we were working in the lab at around 6 or 7 in the evening when I heard a "crack" and I thought I saw our pcb jump. We didn't think much of it since we found a screw on the floor and figured it must have fell on the board and landed on the ground. Anyway, later on, we discovered that our phase shifters weren't working properly - in fact, the biased lines had 0V!!!! After much testing (and prolly cursing,) we realized that (a) our layout was wrong (our PCB was designed for a 900MHz component's layout, but when we had it replaced with a 400MHz one, we didn't think the pinouts of the new component would change too, esp since it was from the same manufacturer and in same casing, etc.) and as a result of (a), we had (b) fried one of our op-amps. So yay, now we really have nothing to show next wed... :D
On the bright side, time to focus on our poster and presentation...
Oh, I've also decided to go with the techy course. Gomen! I sat in on a class and I actually enjoyed it (since it was kind of informal) and I learned stuff. (Not that I wasn't learning stuff in my east asian course). I finally decided to drop east asian because I really want to learn about the history more so than the culture it is now. From what I could gather from my 3hr class, while the prof did talk a bit about the history, she focused more so on the culture we see today, and then maybe talk about how it came to be. I don't blame her since the course is supposed to be about the culture, and it's supposed to cover China, Japan and Korea, so there's no possible way to start from "Day 1" for each... but I wanted to learn more about their history, and then see how their history brought about the cultures we see today, not the other way around. It was a tough decision, but since I enjoyed the other course more, I decided to go with it. Hopefully I'll find time to learn about them on my own... hrmm, since someone made it into Mandarin this term - if he keeps it, maybe I'll borrow his txtbook and learn how to read/write something other than 一二三四 :D
And no, I'm not jealous... DS9 rules! No talk-back! (or whatever that line is...)
