Questions
How big is the Thermochromic clock controller PCB?
It measures 120.6 × 73.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Thermochromic clock controller use?
90 parts, built around the WEMOS D1 MINI, DS18B20, 74HC595 and FDS9926A. 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 Thermochromic clock controller KiCad files?
From the vonsivers/Thermochromic-Clock-Frame repository on GitHub, at the commit this page was made from: the board is PCBs/thermochromic clock controller/thermochromic clock controller.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Thermochromic clock controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask vonsivers before reusing the design.
