Take your body weight in pounds and divide that number in half. That's the total number of ounces of water you need to drink on a daily basis before any diuretic beverages or strenuous exercise. For example, if you weigh 120 pounds, you need to drink 60 ounces of water a day.
MMIC MSA-0686. A Monolithic Microwave Integrated Circuit, or MMIC (sometimes pronounced mimic), is a type of integrated circuit (IC) device that operates at microwave frequencies (300 MHz to 300 GHz). These devices typically perform functions such as microwave mixing, power amplification, low-noise amplification, and high-frequency switching.
I make a loud speaker for a clock radio using a piezoelectric crystal. Actually I experiment with a variety of piezo crystals. That includes a piezoelectric igniter crystal from a BBQ lighter and a homemade/DIY rochelle salt piezoelectric crystal.or showing how to light an LED using a piezo crystal from a gift card, see: http://youtu.be/laSQ6yd7jaE. For using a crystal earpiece or a piezo buzzer with a crystal radio, see: http://youtu.be/HZZmKZJrIW0.
