Electronics buff hand-draws and etches custom PCBs at home — functional home-etched PCB runs a 3D-printed fume extractor fan
A maker has developed a unique method for hand-drawing and etching custom printed circuit boards (PCBs) at home, moving away from traditional computer-aided design. Utilizing a Pentel N850 permanent marker as a photo resist and ferric chloride for etching, this process allows for more artistic and less rigid PCB designs. The resulting custom PCB was successfully used to control a 3D-printed fume extractor fan for a soldering workshop. AI
