This battery saver circuit can automatically turn off a small piece of test equipment after a desired period of time, allowing you to leave your shop worry free.This circuit uses a CD4011IC to act as a simple timer. One section acts as an RC discharge timer (pin 7). This causes ils output to go low, holding the three other outputs high acting as a 9-V source.
