The AC frequency as a clock source will also be a problem of the utility happens to mess with that timing. Forget why the do, but it happens.

A guy selling kits to make a all-parts-exposed digital wall clock that uses *no ICs* and *no crystals*. You build it yourself, 1250 parts to solder onto a custom board. Too pricey for me, otherwise I'd love to put one together.
ICYW, I dug around the FAQ and he is cheating a bit: he's using the 60Hz of the AC as a timer source.
Hmm, since it plus into AC, does that mean touching some parts of the exposed circuits might give you a nice zap? _______________________________________________ Roundtable mailing list Roundtable@muug.mb.ca http://www.muug.mb.ca/mailman/listinfo/roundtable
