This is a page I made back in 2000 when I installed a Davis weather station on my house. The station is still deployed and working, but the computer interface never worked reliably. I suspect that David now has decent software than runs under Max OS X, but I've not kept up.
This is my old GPS page, also dating from around 2000. I no longer have a GPS unit installed in my current vehicle, but GPS navigation devices are much more common than they were five years ago. It's a real shame that most (all?) airlines no longer permit GPS use by passengers, although if the airlines begin allowing cell phone use I just don't see why they'd continue to ban a passive device like a GPS receiver. I guess we'll have to wait and see what happens next.
