Over the past few months a pair of mind-blowing videos have been made based in the parts markets in China. Scotty, the iPhone Guy, started with the question -- these markets have all kinds of spare parts for iPhones, but can you assemble enough of those parts to build your own iPhone. It took him a few weeks to accomplish the task, but he did so, and that phone works. For the second video, he wanted to add a headphone jack to the iPhone 7, which ended up as a grindingly difficult project that took 17 weeks to finish. But, it works. The question is whether Scotty will only do iPhone projects, what's his motivation, is he going to do more work like this, and so on.
He has a broader plan in mind, to explore other technology hubs, to explore the technology supply chain, and so on. We can expect his work to have great technical depth, going into literal nuts and bolts.
This video is an interview with Scotty as they walk through the building housing those electronics markets.
