Making hard pcbs at home In my latest DIY adventure, I explored nickel plating to harden PCBs at home. I was inspired by a slick resistor box design I found through EEVBlog, which had an incredibly cool switching technique but left the PCBs vulnerable to wear from contact scraping. Despite some initial mix-ups and challenges—like dealing with steel instead of pure nickel, using the wrong voltage, and dealing with contamination—my experiments led to some promising results. I even compared the scratch resistance of plated vs. original PCBs in a very informal test. I wrapped up by sharing some handy links for anyone eager to dive... 16 February 2024
