The Sun Up Alarm Clock prototype works as designed. With light on the photocell, the transmitter provides a RF (radio frequency) signal that a nearby AM radio can receive. A schematic diagram for the wireless device was created using ExpressPCB Schematic software. Also, a block diagram has been drawn showing the basic components of the wireless gadget. I'll experiment with the reception range by adding a wire antenna to the device.  This project is an example of Neil Gershenfeld's Personal Fabrication concept. More discussion on this topic to follow.

Rebuilt the website making it more user-friendly and less clutter. Plan to publish great hands-on material on computational devices for "robo" based sci-tech projects.
