This LM3909 flasher circuit can be used as a variable-rate warning light, or for advertising or special effects. The rate control can adjust from no flashes to a continuous on. The miniature 1767 lamp can be flashed several times per second. As a toy, the flashing rate can be adjusted to mimic the strobes at rock concerts or the flicker of old-time movies. In a dark room, the flashes are almost fast enough to stop a person's motion. National Semiconductor Linear Applications Handbook 1991 p 397
