Philip, I am interested in your design challenge for an accurate digital clock, but although I've searched the IEEE Spectrum on-line magazine, I can find no mention of it. All I have is an email from you circulated through the TimeNuts group.
It will be important to know the ground rules for the project. For example, what is the expected operating environment? What is the power budget? Need the display be 7-segment, and is any other technology permitted? Where, when and how is the calibration to be performed, and over what time period will accuracy be checked, and by what method? Most especially, we need to know what the definition of parts being 'generally available' means, and we need to know who decides how the cost of construction is defined. I published a $30 design using recycled parts capable of 10sec/year some two years ago - how would I know if it would it be eligible? Please send me detailed information, or tell me where I may find it. If it's not been clearly defined then the competition will not generate any serious interest.
