PCBWay Supports High Precision Advanced PCBs: https://www.pcbway.com/ Inspired by a futuristic black Trans AM from the 80's, here's my take on an LED back-and-forth scanner using 8 LEDs with a 4017 based circuit. There are similar LED chaser circuits using only 6 LEDs with one 4017, but this project uses two 4017's and a customized transistor LED driver to allow the brightness to fade out similar to light bulbs turning off, giving a more natural visual effect.
