One problem remains, which is getting hold of a 32KHz crystal. I have never
bought anything from Digikey. The part I need is XC972-ND and is priced (UK
pounds) £0.47. However I notice that there is a £10 handling fee and £12
shipping! The total order cost would be £22.47, for one simple crystal.
That's about US $41! Therefore does anyone in rec.radio.amateur.homebrew
reside in the US, order frequently or in the near future from Digikey, and
wouldn't mind adding one of those to their order and popping it in an
envelope to me - I'll pay all costs of course as long as you don't charge me
£10 handling ;-)


Over here you can sometimes buy those little stick-on digital clocks,
made for sticking to your bathroom mirror. They cost about $3 and
include a crystal, a display, and a battery, plus all the circuitry to
make them work together.

I think their exact frequency is 32,768 (= 2**15) Hz, so that dividing
by 2, 15 times will count seconds. If this will work for you then
buying one of them might be a very cost effective way to pick one up
easily. If you can't find one there, I think I have one which I
salvaged out of a dead watch.
