The early generations of the iPod are not only valuable for collectors or Apple fans in general, but also for DIY enthusiasts who apply all kinds of mods to them, including larger batteries, capacity expansions, and operating system changes. One of those enthusiasts is David Buchanan, who took his first-generation iPod Nano and turned it into a USB-C compatible device, leaving behind the old proprietary 30-pin connector.
There are days when we miss the simplicity of the first MP3 players. Today, the music function is little more than an app, but to get to it we must turn on the device, enter the PIN or pattern, ignore notifications, swipe here, swipe there, browse the app list... and maybe more.
That is why we are not surprised to discover that many users still cling to their dedicated devices. This is especially true with the first members of the iPod family, which often appear online at very interesting prices, as long as there is the willingness to change a depleted battery or replace a broken screen. However, the story does not end there, because those iPods have proven to be very hackable. For example, did you know that you can upgrade an iPod Nano with USB-C?
How to upgrade an iPod Nano with USB-C
In recent days, the enthusiast and youtuber David Buchanan published a video in which he explains his purchase (via eBay) of a first-generation iPod Nano with a depleted battery. Not having a replacement battery on hand, he wondered what he could do with the player while waiting, and discovered that there was enough space to install a USB-C port, since the Flash chips on that iPod model are soldered one on top of the other.
The USB-C port is a donation from a USB-C to micro USB adapter (also from eBay) with a small PCB that simplifies the soldering process. The most aggressive part of the mod, so to speak, is the removal of the 30-pin connector. David adopted the Lieutenant Ripley diplomacy with pliers and a bit of force. The final extraction left the iPod Nano with all the original pads ripped off the PCB... but the truth is he doesn't need them.
Small cables, and the exact dose of epoxy
In the final electrical phase of the mod, David managed to expose a bit of copper on the PCB to serve as an anchor point for the USB-C port, took 5V and GND from two specific points, and the two data lines are on the other side of the PCB. Soldering such small cables requires a lot of patience, and as if that were not enough, one of the chips had to be sanded to reduce its height and allow the installation of the USB-C port.
The rest is a matter of aligning the aesthetics of the iPod Nano with the new port, and for that, David used a bit of epoxy, which sealed the leftover space and adapted wonderfully to the shape of the port. The iPod charges its new battery and syncs with iTunes without difficulty. Now, some will not hesitate to point out that with this mod, the iPod Nano loses compatibility with 30-pin accessories, but personally, I think it is a mod in the right direction.
