Driving the relay from 3V is (or might be) only the part of the problem.  I
will look at the circuit first thing tomorrow to see if I can catch some
ideas (it's 1am here)

Thank you for your answer,

Regards,

Omer

5V

Accidentally deleted one of your later mails, but did you say you wanted to
convert Hall sensor pulses to reed switch pulses ?

If so, can you use this circuit

http://www.piclist.com/techref/io/relays.htm

"Lowest cost for 5V only supply with higher voltage relay coil"

to drive the reed with 3V, eliminating the need for the 5V ?
