The good news is that the reverse saturation (leakage) current for a 2N2222 is going to be in nano amperes. I never considered the possibility that current could flow from the collector to the emitter without power to the base. A little ignorance goes a long way. Quote

Getting timers or timer circuits that delay shut off for 15 or 30 seconds is easy. One that delays for 10 to 12 minutes was a lot more difficult (at least for a non electronic guy). Quote
