NPR/NGS RADIO EXPEDITIONS Show: Bug Communication Log of DAT #: 1 Date: 1999 ng = not good ok= okay g = good vg = very good Absolute Time total time 2.01.57 0.00.00 -0.02.17 messing around with camera and mic set-up. 0.02.17 -0.04.58 Alex explains to someone about how to make accelerometers and set them up. 0.04.58 -0.07.45 engineers talk about pre-amps with RC. 0.07.45 -0.08.20 AC: How does a biologist learn so much about electronics? RC: I took the most useful course I ever took, which was an electronics course at the community college up in Ithaca. I never learned anything that practical up at Cornell.! took a little course and got a little certificate that I'd completed this electronics course and I didn't really learn enough to be able to design my own circuits, but I learned enough to be able to follow one. So that's an extremely useful-that and Spanish were maybe the two most useful courses I've ever taken. 0.08.20 -0.09.11 Camera people talk about things. 0.09.11 -0.1 0.03 AC et al. Talk about coffee, camera stuff, general stuff. 0.10.03 -0.11.47 camera people get the accelerometers set up -lots of feedback, chatting about it. 0.11.47 -0.12.06 false start 0.12.06 -0.13.09 RC: Because these phono cartridges are so sensitive, that I thought it might be worth trying to rig up one for use in the field which is difficult, but by mounting it to this little clip, we can attach it to a branch and have the tip of the stylus touching some other part of the branch and get a pretty good signal but what I want to do now is use one of the ones that Dennis made up this morning that has a nice light cable which'll make positioning easier and then mount it on another little clip here so that we can attach it and then we'll run that down come out of the speaker. AC: So where are those that we had made at NPR RC: Oh, I've got them over here, and then what I was going to do is get a little bit of tape from Ned or somebody, and -this works, I was hearing some great calls just now... AC: we're probably too late, they probably won't call again ... 0.13.08 -0.14.14 RC setting up the accelerometer on a branch. Crickets, birds, far plane. 0.14.10 -0.14.36 Good ambi (cicadas!) with talking-RC: "let me just make sure this is connected and sounds good, and then we can try running it into the speaker ..." great ambi here or cicada -no planes! 0.14.36 -0.15.47 AC: What are you doing? RC: I'm just trying to get a good contact here between the stylus on the phono cartridge and the part of the plant, mind you this is not in the manufacturers instructions for these phone cartridges AC: What you're doing is, RC: This is an awkward system, I think we could probably improve on it with another 15 minutes in the NPR shop, AC: So you're clipping this little phono cartridge on the woody part of the stem and trying to rest the needle on one of the green sub-stems that comes off of it? RC: yeah. The technique as I said, especially developed for Radio Expeditions -don't tell anyone I did this. All right, let's see how this sounds ... 0.15.47 -0.16.49 AC and RC chat about the sounds they're getting from their accelerometer. Then how they're recording it, and setting in up with a speaker. 0.16.49 -0.17.30 a lot of mic bumping here at the beginning (but good info) RC: There's a guy I know in Arizona who studied vibrational sounds of velvet ants, long before anybody else had really -most people had begun being aware of this kind of communication, And he's great at working out gadgets u...
