Looking forward to it. Also, reading back, I realized that it's not intuitively clear what I mean by "full scale" or "half scale", so here are some pictures. 5mA for the half scale one and 11mA for the full scale. Note that the tubes look *much* dimmer than this as it was taken in a dark room with a long exposure.
