<< Matt; I am with you on this one. Ihave used SCR's in CD ignitions with good
 results. The fact that 555are now giving up suggests no isolation between
 the timer and the MOSFET or the power circuit. a simple 7812 regulator
 should help and an opto isolator between. The use of a SCR requires some way
 to disconect power from the output so the SCR will turn off. I use a choke
 in series with the DC supply or 1/2 wave dc to disconect.

Ok so SCRs could be a great alternative?And yes I remebered about the SCR 
needing to be turned off right before going to sleep.Heh.So a choke would 
disconnect it?
