Overview
Blinky board is an open-source printed circuit board by odyesey, from the odyesey/555-LED-Chaser repository on GitHub, published under the MIT licence. It is a 2-layer board of 64.2 × 50.9 mm with 19 parts on 18 nets, routed with 173 tracks and 0 vias.
It is built around the NE555P. Its parts include 10 diodes, 2 capacitors, 2 resistors, 2 ICs and 1 connector.

I designed Led chaser in diamond-shaped pcb (to give superman look). I accomplished this by following a guide. I tried to avoid via's in pcb and I did it
Gerbers and BOM are in the production folder
Note: Potentiometer doesn't making any changes in speed, most likely wrong potentiometer or less likely wrong schematic

Questions
How big is the Blinky board PCB?
It measures 64.2 × 50.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Blinky board use?
19 parts, built around the NE555P. 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 Blinky board KiCad files?
From the odyesey/555-LED-Chaser repository on GitHub, at the commit this page was made from: the board is kicad_files/blinky-board.kicad_pcb and its schematic kicad_files/blinky-board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Blinky board design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
