I love my iPhone, but it doesn't have a headphone jack! So I decided to add my own. For real.
Allen went through many iterations and a lot of debugging to get his creation working. He went through three complete iPhone 7 devices, a handful of screens and numerous internal components.
"I ended up designing lots of circuit boards that were more complex than anything I’ve ever done", says Allen. "I had three iterations of PCB designs manufactured, and 4 different flexible PCB designs."
