README

The running light is achieved by a circuit of a clockgenerator NE555 (U1) and two shift registers TI4017 (U2, U3). The NE555 uses the clock signal to shift one bit through both shift registers. At the end the circuit is reset and the cycle starts anew. The outputs of U2 controls the 20 LEDs (D1-D20). Since the TI4017 only has 10 outputs, one output controls two LEDs. U3 controls one transistor each (Q1, Q2) using two outputs, which alternately pull D1-D10 or D11-D20 to GND. This process repeats itself.

Questions
How big is the SMD Lauflicht 0805-0603 v1 1 PCB?
It measures 28.6 × 5.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SMD Lauflicht 0805-0603 v1 1 use?
55 parts, built around the NE555 and CR202320F. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the SMD Lauflicht 0805-0603 v1 1 KiCad files?
From the Binary-Kitchen/SMD_Lauflicht repository on GitHub, at the commit this page was made from: the board is Kicad_Files/SMD Lauflicht 0805-0603 v1_1.kicad_pcb and its schematic Kicad_Files/SMD Lauflicht 0805-0603 v1_1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SMD Lauflicht 0805-0603 v1 1 design in my own project?
Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
