Geiger counter (analog) CPU meter

SilentQ writes – “A few months ago I picked up a Geiger counter. I had no idea what to do with it. Then one day, I was playing with it, and looked at the analog meter, and thought I would try a hardware CPU load meter. I’ve seen all sorts of software analog meters, but the only analog hardware I’ve ever seen is CPU temp, or fan speed. That kinda stuff. Doesn’t mean that nobody ever did one, but if there are others who have done hardware analog meters, I’ve not found them…” – Link.
