This is a NE555-based timer circuit to simultaneously control two independant relays, with a momentary push-button starting a roughly 10 minute "on-time."
D1 is sort of redundant, but I want to keep it in the circuit strictly as a protective measure for the NPN transistor Q1.
I absolutely welcome any critiques you may have, but please be gentle, this is my first time!
I'm an audio engineer (commercial system design), not an electronics engineer, and oddly enough, THIS design is for my race car...
Thanks!
