A simple PIC-based tide calculator for paddlers, dabblers, and kings of the sand castle.

For over ten years, the author had felt that his power over the waves was also severely limited. Not in some megalomaniac sense, you understand, but in trying to write a computer program that would allow him to predict the state of the tide for any of his favorite coastal laze-abouts.

Could he walk out to that rocky point without having to swim? Could he swim in that broad sweeping bay without having a kilometer walk out across sand?

All too often, and too late, he'd found that the answers were negative! What was needed was a device or computer program that would allow the answers to be immediately displayed. Naturally, it would allow predictions to be accurate within minutes - the mechanism of tide movement was, after all, subject to strict laws of nature and thus readily calculable…

Huh! How naive! But the author's ultimate solution makes for a fascinating read and a highly interesting project.
