The circuit above energizes the relay after a sec or so. It works great except that I can drive the base any harder because of the resistor. I know I could reduce the resistor but then I won't have to timing element. The Vce is amost 2 volts and thus cooking my little 3904. I know saturation depends almost entirely on collector resistance which is the coil at 120 ohms. I'm sure there's a simple solution but boy am I stumped.
Thanks in advance
