does anyone have any ideas, diagrams for ways to measure current (preferably without interrupting the line). i was thinking of one of those hall effect sensors, with the core (ferrite?) around the line. i want to use it to drive a 20 led bargraph display (using two LM3914's) and create an analog display, with the leds around it, and current measured on the front, and i can also calibrate it to work. sorry about the crappy picture, it's a stretch of an ammeter cut from another picture, but just give the general idea. it would be good as well if there was a schematic for a 2-3 digit led numerical display ammeter
