- First draft of user manual is up.
- Technical document is in its early stages
- Unfortunately, the sound card driver
only works in windows 95 so Ben and I spent a good part of Friday
afternoon trying to install 95 over NT - Russ Taylor provided us with the
windows 95 cd. I reformatted the hard disk and got the cd driver but got
stuck in the windows 95 installation because we didn't have the right code
number from the cd. This should be finished on Monday when we get the
right number from Russ.
- I hooked up the lightning detector to my pc and wrote a driver class for it.
Right now it looks like a reasonable installation will be to put the
detector on one of the lightning rods on the roof (it needs to be on a
grounded metal rod). I don't know of any easier way of testing the
detector other than mounting it on the roof.
- The preliminary tech doc is at http://www.cs.unc.edu/~awilson/tremble/design.html. It is
purposely vague about implementation (aside from a couple of message
loops that I know need to be in there) to allow everyone to do
whatever is necessary under the hood.
Basically, we've got four modules: acquisition, analysis, storm
manager, and visualization. They all communicate through some network
connection. (I'm leaning toward BSD sockets because I know they'll do
what I want. If VRPN_Text is suitable, we might use that, too.) I've
written out rough interfaces (by way of messages they can send and
receive) for acquisition, analysis, and storm manager; visualization
isn't in there just yet.
- I am almost done with the startup interface and client/server code; as well as modeling landmark buildings for the viz app. I have to take a look at the interface that I will have to wrap my code around. The idea is to send commands and schedules from the web application startup page and then send the information to the Thunderpc-cs, but I need a better idea of the network interface that we will use (probably vrpn) to communicate with the other links of the system.
- I worked on more topological map code. It is fairly difficult to work with, since information about say, elevation, can be split among several different files. I am still trying to break down the topo map viewer code that I have to figure out how to pull out just the elevation information.
- Worked with Adam on Thunderpc-cs installation and setup.
- Our pc, Thunderpc-cs is now installed in Room 360 (The Thunder Lab). Surprisingly it isn't a 486, but
a P2-300 with 64MB or RAM and a 4.3 GB HD. So it looks like it will do what we need it to do, yeah!
- We got the soundcard and lightning detector. David Harrison also provided us with a single temporary microphone and preamp so we can get some idea of the quality of our audio signal.
Small Pitfalls this week:
- Ben and Adam spent an inordinate amount of time on hardware setup. We did not anticipate this; however, things seem to be progressing nicely now, since we finally have our pc setup properly.
- The topological map code is very hairy, and with Eric about to take his CCE exams, there may be a problem with staying on schedule where the map code is concerned. We will have to discuss this further to see what we can do about this, or find an alternative to using those maps.
