Summary

  • Engineer Jeremy Cook has designed business cards made of PCB that also function as tools, in a bid to make them more memorable to recipients, and wrote up his experiences for anyone else to try.
  • His designs include an LED version with a coin cell battery holder for lighting up the card, and another incorporating a ruler, circular stencil and simplified protractor for drafting.
  • Having learned that solder mask colour options have expanded beyond the standard green, he experimented with finishes from different manufacturers to enhance the artwork on his cards.
  • Cook emphasises the importance of researching fabricators to learn the limitations and options for custom PCB designs, and suggests Hackaday’s 2024 Business Card Challenge winners for further inspiration.
