I found that. More than once. That's for an LED bargraph. I'm looking for a circuit that operates an old-fashioned galvanometer- style panel meter with a needle that swings from side-to-side. I can invent my own - a simple ladder D-to-A to produce a variable voltage out of the parallel port. I was hoping to save the math and use resistor values that someone else has calculated, but after two days of searching, I guess I _will_ have to go do it myself. Somewhere in my junk boxes, I have some .5" tall by 1.5" wide signal meters that I think I pulled from a dead CB radio, c. 1978 (pre-40- channel). The plane of the needle swing is parallel to the floor, and the needle has a 90-degree bend at the end, so you see a .2" tall vertical line slide from left to right as the signal improves. If I can find it, it'll mount perfectly in a 3.5" blank faceplace. Now to excavate the old parts! -ethan
