David Mills's Internet Shed
Welcome to the webshed One of my homes on the internet.
Friends & family that have ended up here are probably lost, anyone looking for my photos probably wants to be at Flickr instead. Academic visitors are directed to my research pages. Radio amateurs may be interested in my Ham Radio and Radio Projects pages. My radio callsign is G7UVW.
