Bringing Back the iPhone7 Headphone Jack

Plenty of people bemoaned Apple’s choice to drop the 1/8″ headphone jack from the iPhone 7. [Scotty Allen] wasn’t happy about it either, but he decided to do something about it: he designed a custom flex circuit and brought the jack back. If you don’t recognize [Scotty], he’s the same guy who built an iPhone 6 from parts obtained in Shenzhen markets. Those same markets were now used to design, and prototype an entirely new circuit.

The iPhone 7 features a barometric vent, which sits exactly where the headphone jack lived in the iPhone 6. The vent helps the barometric …read more

Death To The 3.5mm Audio Jack, Long Live Wireless

There’s been a lot of fuss over Apple’s move to ditch the traditional audio jack. As for me, I hope I never have to plug in another headphone cable.

A 3D Printed Camera (Including The Lens)

Posted on by

Barring the RepRap project, we usually see 3D printers make either replacement parts or small assemblies, not an entire finished product. [Amos] is the exception to this rule with his entirely 3D-printed camera. Everything in this camera is 3D printed, from the shutter to the lightproof box to the lens itself. It’s an amazing piece of engineering, and a testament to how far 3D printing has come in just a few short years.

35mm film is the most common film by far, and the only one that’s still easy to get and have developed at a reasonable price. This 3D-printed …read more
