I don't have much experience with a 555 or a PIC for that matter, but I would seem to think a PIC would be easier to implement and possibly more accurate. <br><br>Just a thought.....<br><br>73's<br>Stephen<br>K1LNX

I am in need of a schematic (or complete unit) for a timer that will run<br>off +12v and pulse a relay every 15 mins. The relay should stay on for<br>10secs. I think it can be done with a dual 555, one for the 15mins and<br>
the other for10secs.<br>Anyone got any ideas. I need this to turn on the TNC and Transmitter for<br>a solar powered wx station I'm trying to build<br><br>Thanks<br><br>John<br><br>--<br>John Mc Hugh, K4AG<br>Coordinator for Amateur Radio
