I have a PIR motion detector designed to sense if someone is walking
towards my house.
In addition to a dial for adjusting PIR sensitivity, this motion
detector unit has a photocell mounted to face downwards.  The motion

I am looking for a compatible IC for a Holtek HT7713B.  Seems like
Siemens made SLB0586/0587 ICs, but are these the compatible ones ?
Does anyone know where I can find a data sheet for the HT7713B?  I
found one for the HT7700 type.

I'm trying to identify a small 0.4 mm x 0.4 mm 6-pin DIP IC chip that

rotated 90 degrees :-). Anyway its package has a ceramic base with

I've purchased a phone system that's capable of releasing typical

In another posting I asked for ideas on how to  add red and green LEDs to
the switch tracks of an N Gauge model electric train.  See below for my
earlier post.
It seems like the way to go would be with  DPDT Dual Coil Latching Relays.
