i got bored in the lab today, so i spent about another hour and a half finalizing the schematic. as promised, here it is:

i was having issues with the output voltage from the LT1011, it wasn't where i wanted it to be. basically, i wanted it to be either 0 or 5 volts, which would feed the 2N3904 transistor that drives the relay. i wound up putting a 10k pull up resistor beween the 5 volt feed and the output of the LT1011 and everything became happy. oh yeah, there's a diode that goes across the relay. my relay has a diode built in, (you can tell if you reverse the polarity with the trigger winding and see if it still works or not, if it only works 1 way it has a diode) but if anyone wants to put this circut to use and they choose a relay that doesn't have a built-in diode, i suggest that you stick one in there so the inductive kick from the relay doesn't damage the transistor.


what a mess!


the relay, had the ohm meter hooked up to it to make sure it was closing the circut (although i could hear the thing clicking)


my white ass blowing into a tube and watching the ohm meter switch from open circut to short circut


well, that's about it. i proved to myself that it could be done. it wasn't even that hard. all i need to do now is solder everything together for real, (it's sooooo fustercluck right now with all of the clip leads, but it works) put it in a nice box, and install the damn thing.
