Greetings everyone.
I have a number of network unreliable network appliances scattered out
across campus that have to be visited often, and the reset button
pressed. Some days I spend a lot of time doing this.
I'd like to build up a simple timer circuit that would generate a
positve pulse of non-critical duration, say 2 seconds, every hour or
so. The hourly pulse should be 'astable', i.e. i'd like it to occur
over and over, every hour or so. I'll take the pulse and use it to
trigger a circuit to close a relay, to which i will wire the leads of
the reset switch. Automate pressing the reset switch...
I did a little TTL design many years ago, but i don't remember much
about it.. It's been a long time.
If some kind soul could sorta get me started here, I'd sure appreciate
it. I may need to build up several of these if this works out..
Kindest regards,
Russ
