Questions
How big is the Light Meter PCB?
It measures 60 × 90 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Light Meter use?
26 parts, built around the MCP6002T-E/MC, HS96L03W2C03, L78M05ABDT-TR and LM336Z5. 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 Light Meter KiCad files?
From the davidrihtarsic/davidrihtarsic.github.io repository on GitHub, at the commit this page was made from: the board is Projekti_iz_elektronike/Vsebine/Studijsko_Gradivo/circ/800_NacrtovanjeOhisja/Light_Meter.kicad_pcb and its schematic Elektronika/Skripta/sheme_vezij/Polvalni_usmernik_dioda.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Light Meter design in my own project?
Its repository states no licence, so its author keeps all rights: ask davidrihtarsic before reusing the design.
