does anyone have a circuit for those phone
thingies that cuts off one device when the
other is already in use?
commercial ones look exactly like a phone
adaptor, you know, those things that give
you two phone jacks when your wall has only
one? there are only four components added:
two leds, and two silicon diodes (glass
case). i will demonstrate when i re-install
windows. right now i am browsing with
arachne.
below is a test if text schem works.
led1
+--|<--+
| | d1
in grn o---+ +----|<---->|----o grn out
| | d2
+-->|--+
led2
the green terminal is the second of four,
when looking into the phone jack, with the
notch up. (yellow, green, red, black)
that is the added circuit for the second
phone, the one that gets cut off.
d1 and d2, are unknown values nor diode
types. any help appreciated.
