To lower interference from devices outside the space taken up by your circuit, there are a few things you can do. You can place the circuit in whats called a "Faraday Cage", which dissipates electrical fields at the surface of the enclosure, which is made of conductive metals. Actually, if you've ever seen a movie in which a paranoid conspiracy theorist rocked back and forth while wearing a hat made of aluminum foil, he might have what you're looking for. Such metals reflect many different wavelengths, and are therefore useful for electromagnetic shielding. Also, make sure to put your power supply through several chokes, and put some kind of iron core ring around the cable that plugs into the outside power source (e.g. 120VAC household). Good Luck!
