Questions
How big is the NTSCope PCB?
It measures 53.1 × 59.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the NTSCope use?
38 parts, built around the LM1881, PJRAN3X1U03X and RCJ-041. 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 NTSCope KiCad files?
From the miakizz/Videoscope repository on GitHub, at the commit this page was made from: the board is NTSCope.kicad_pcb and its schematic NTSCope.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the NTSCope design in my own project?
Its repository states no licence, so its author keeps all rights: ask miakizz before reusing the design.
