Subject: [alt-beam] New? Voltage dependent SE

I was thinking the other day about something someone said (Jvernon maybe?) =
about needing to get a new SE. I came up with this idea and was wondering =
if anyone might want to build it for me. I only have one flavor of voltage=
detector.
Here's how it works:
The voltage in the cap charges up to the trigger voltage of the high voltag=
e 1381. When it turns on it turns on the lower voltage 1381 which turns on=
the 2N3904 and 2N3906 in succession. When the 3906 turns on it keeps the =
low voltage 1381 turned on until it reaches its threshold. The result of t=
his circuit is an easy to control voltage trigger system that is not time d=
ependent. =
Thoughts or ideas?
