A little while ago I posted an article on The how big, how long and how many of ground radials. While grounding for low power AM is an oft-debated issue, one thing we all agree on is that burying copper is a pretty expensive activity. Imagine my surprise when I discovered a limitless supply of free copper, just waiting to be dutifully bur.......

The LT1116 is an ultra fast (12ns) comparator designed for sensing signals near the negative supply. The input common mode range extends from 2.5V below the positive supply down to the negative supply rail. Like the LT1016, this comparator is specifically designed to interface directly to TTL logic with complementary outputs. The comparator may operate from either a single 5V supply or dual ±5V supplies. Tight offset voltage specifications and high gain allow the LT1116 to be used in precision .......

The post discusses a simple deep under soil metal detector circuit for evaluating hidden metals such as gold, iron, tin, brass etc by detecting change in the resistance of the relevant soil layers. Bigger physical objects which might be buried within the topsoil could be unveiled through a modification in the electrical resistance of the soil layer at various depths. The design is about a device which may be for implementing relative enhancements on the resistance of the soil. This particular ap.......

UL requires that an electrical system using a metal chassis earth ground connection have a resistance of less than 0.1 ohms. This resistance must be tested with actual line current in excess or 10 Amps.  The circuit shown uses a couple of LEDs to indicate if in fact the resistance is less than 0.1 ohms.  It uses a modified transformer to produce a 2.5vac output with at least 10 Amps of supply current........
