An eight-pin micro multiplies, monitors, and delivers a boosted voltage to a load The circuit in this Design Idea uses a Microchip PIC12F510 controller to drive a voltage multiplier ladder and a single pin to output status and to input a trigger signal you supply (Figure 1)....

Voltage-monitoring circuit is based on Microchip 12F675 MCU Lets users set up a tolerance around a specific value A voltage monitor is a common hardware need. But beyond a simple compare, many systems must provide a tolerance around a specific value. Specifications of 2%,...

If your freezer fails you may have meat or other frozen stuffs ready to eat. Re-freezing, not generally considered an option, may be an alternative for you, but may be also a risky business. While for a short time, a freezer should maintain an acceptable temperature to keep...
