Have a look at All ABout Circuits, and Elactr Tech Online. Those two will supply ideas galore and help with the technical and electrical circuits required to make them work properly. I have been studying electronics at home through the first one and I can tell you that it is a complete training class from beginning to end and will spark your imagination to new and better ideas everytime you visit that site. If you need more help LMK and I will give you some more of the links I use regularly to build all kinds of devices for home, shop, brewery and plasma table.
