1-Wire Weather Station

This is a real-time weather station I built using an AAG electronica instrument and an EEE 701 for the server.

I coded the server in Java using Apache’s Mina library for non-blocking sockets. The client is FLEX, and uses Socket (rather than HTTP). The webcam service consists essentially of a Java class that reads the video4linux data as raw RGB and saves it to a JPEG which is then streamed over the socket along with all the other data (I built the server to be pluggable, so each of these little add-ons is a plugin that shares the stream with the other plugins). The archival data lives in MySQL.
