I finally broke down and bought the Arduino based weather station wireless sensor receiver. You can see the project here: http://www.osengr.org/WxShield/Web/WxShield.html . This device works with the open source software Weather Station Data Logger. The new WxShield also has a barometric pressure sensor and temperature and humidity sensors so it replaces the base station for a computer interface. The cost of the WxShield was $135. It works with all Oregon Scientific sensors. I use the old base station as a handy display now.

It looks the same as before.
Reasons to upgrade to the WxShield:
- More reliable. The Oregon Scientific base will stop broadcasting data over USB periodically. No pattern really but it happens about once a month. I had it happen 3 times in a month and other times go 3 months without it happening. Frustrating though.
- Ability to install external antenna. This is a big deal when your PC you use to upload the log the data is in your basement. The external antenna really extends the range. This device lets you run a coax to route the antenna outside.
- Improved barometric pressure sensor. Much higher accuracy.
- Improved indoor temperature and humidity. It can also be remotely located.
- Its just nerdier.
