Electronics buff hand-draws and etches custom PCBs at home — functional home-etched PCB runs a 3D-printed fume extractor fan
Elliot Andal, a maker and electronics enthusiast, has developed a technique for hand-drawing and etching custom PCBs at home. Using a Pentel N850 marker and ferric chloride for etching, Andal created a PCB for a 3D-printed fume extractor fan. The process highlights a creative alternative to traditional factory-produced PCBs, emphasizing artistic design over standardization.
- ▪Elliot Andal perfected a hand-inking and home-etching process for PCBs.
- ▪The Pentel N850 marker was identified as the best photo resist for the project.
- ▪Andal's final PCB design included artistic elements and the ALTco logo.
