(no subject)
Turned in my penultimate QFT set today; one more to go. The last one is due the morning after Carols, and it looks like a beast; at this point I'm not planning on sleeping next Monday.
I'm pretty darned exhausted right now and even though I'm not nearly ready for my fast camera time tomorrow, I think I'm going to bed. It'll just mean a late night tomorrow, although there's so much going on tomorrow (including a practice quals talk for a labmate, the famous "molecular gastronomy" chef Ferran Adria touring our lab, and an unexpected meeting with a thesis committee member) that I expect a rather late evening if I'm to get anything done experimentally.
I had fun getting a nice stable 40 kHz signal out of an Arduino microcontroller board with almost no effort. Obviously it's gross overkill, but we had a bunch of them around and they're really easy to program and use for general digital prototyping. Of course you can get a 40 kHz signal out of a variety of analog oscillators, such as a '555, but the Arduino needs no external components. I think one of the starter kits would make a great Christmas present for a kid who liked the idea of tinkering with electronics, but alas no one in my family fits that description.
