thanks for the hint my transistor is connected the wrong way. i used the exact components that were specified in the article, i think i killed the transistor and the LM339 when i was switching everything around

, so I’m going out and getting some new replacements. right now the relay is turned 180 deg. so the line is facing the bottom. i think it will work once i get the new components because i can manually trigger the relay by connecting pin 1 of the relay and the ground then reset the circuit by hitting the reset switch.
