My latest project: Computerized Goat Farming.
I am a computer geek and am obsessively organized; I have kept all our goat information on computer for years: milk records, health records, pedigrees, etc. Now I can access all of this information from the barn. (why I this is necessary, I an not really sure, but it was a fun, inexpensive project.)
Note the antenna built from a coffee can. See Barn Computer Wireless Network
