Voltage reference [Project]
posted December 12 2013 12:24.44 by spic0m




Member SUF of Dangerous Prototypes forums made this voltage reference project:
"To achieve the things above I designed a small battery good indicator circuit with a zener an opamp two LEDs and a few resistors. If you switch it on and the battery fall below 8V the red LED will lit instead of the green. I wanted to have a SOB style case. I designed a new one with a trick on it. I used a third acrylic plate what has a hole inside. The hole can accommodate the battery and the battery clip. This setup keeps the battery in place."
