The iPod in question was a 5.5th generation model, prized for being the last to feature the Wolfson DAC with its good audio quality. [Ellie] used the ever-helpful iFixit guide to learn how to disassemble the device safely. Careful hands and a spudger are key to avoid marring the pressed-together metal case.
Once opened, an iFlash Quad board was installed inside that lets the iPod use up to four micro SD cards for storage instead of the original hard disk drive. With two 512 GB cards installed, [Ellie] won’t be short of storage. A new battery was then subbed in, along with a fancy clear front casing for the aesthetic charm of it all.
After the hardware modifications were complete, the iPod needed to be restored with iTunes to start working again. She then installed the open source Rockbox firmware, which opens up the capabilities of the hardware immensely. Perhaps best of all, it can play DOOM! Alternatively, you can use the clickwheel to control the volume on your MacBook if you so desire.
[Ellie’s] project goes to show that modifying an iPod these days can be a fun weekend build thanks to the great software and hardware now available. It’s wonderful to see that the platform still has such great support years after it has been discontinued. If you really want to look back though, take a gander at the early prototype of Apple’s breakout MP3 player.
[production] cites several previous, similar projects that showed how to interface with the click-wheel, a perfectly fitting color display from Waveshare, and open-source software called Rockbox to run on the pi. We all stand on the shoulders of giants.
Some nice innovations to look for are the Pi Zero’s micro-SD card and a micro-USB charging port aligned to the large slot left from the iPod’s original 40 pin connector. Having access for charging and reflashing the card without opening the case seems quite handy. There’s a nice sized battery too, though we wonder if a smaller battery and a Qi charger could fit in the same space. Check the project’s Hackaday.io for the parts list, and GitHub for the software side of things, and all the reference links you’ll need to build your own. It looks like [production] has plans to turn old iPods into Gameboy clones, you may want to check back for progress on that.
Now, we’d like to tell you that he’s already succeeded in this task. After all, in theory, it should be pretty straightforward: just remove the 8 GB flash chip and replace it with a pin-compatible 16 GB version. But of course, this is Apple we’re talking about. Nothing is ever quite that easy, and it seems that at every turn both the hardware and software in the thirteen-year-old iPod are fighting the change.
It took several attempts before the original flash chip could be swapped out, but eventually [Tucker] and his friend [Wesley] got one to survive the operation. Unfortunately, all they had to show for their effort was an unhelpful error screen.
From here on out the assumption was that they were dealing with a software problem. Luckily the Rockbox bootloader had previously been ported to the 3G Nano, which helped get the ball rolling. The next step would be to patch the Nano’s firmware to accept the ID of the new flash chip, but after a year of work, it’s turned out to be a bit more complicated than that.
We didn’t think we’d see another hack involving the aging iPod Classic here on Hackaday again, yet [Franklin Wei] surprises us with a brand new port of Quake for the sixth-generation iPod released some thirteen years ago. Is Quake the new 90s FPS that’ll get put into every device hackers can get their hands on?
The port works on top of RockBox, a custom firmware for the iPod and other portable media players. This isn’t the first game on the device. A source port of Doom has been available for years. [Franklin] decided to use Simple DirectMedia Layer (SDL) to make his job easier. That doesn’t mean this was an easy task though, as [Franklin] describes very interesting bugs that kept him from finishing his work for about two years.
The first problem was that the GCC compiler he was using was apparently not optimizing time-critical sound mixing routines. [Franklin] decided enough was enough and dug into ARM assembly to re-write those parts of the code by hand. He managed to squeeze out a speed increase of about 60%. Even better, he ran into a prime example of a bug that would get triggered by a very specific sound sample length running through his code. Thankfully, with all of that sorted, the port is now released and we can all enjoy cramping our hands around tiny screens to frag some low-poly monsters.
If you’ve been kind enough to accompany me on these regular hardware explorations, you’ve likely recognized a trend with regards to the gadgets that go under the knife. Generally speaking, the devices I take apart for your viewing pleasure come to us from the clearance rack of a big box retailer, the thrift store, or the always generous “AS-IS” section on eBay. There’s something of a cost-benefit analysis performed each time I pick up a piece of gear for dissection, and it probably won’t surprise you to find that the least expensive doggy in the window is usually the one that secures its fifteen minutes of Internet fame.
But this month I present to you, Good Reader, something a bit different. This time I’m not taking something apart just for the simple joy of seeing PCB laid bare. I’ve been given the task of repairing an expensive piece of antiquated oddball equipment because, quite frankly, nobody else wanted to do it. If we happen to find ourselves learning about its inner workings in the process, that’s just the cost of doing business with a Hackaday writer.
The situation as explained to me is that in the late 1990’s, my brother’s employer purchased a Yamaha Mark II XG “Baby Grand” piano for somewhere in the neighborhood of $20,000. This particular model was selected for its ability to play MIDI files from 3.5 inch floppy disks, complete with the rather ghostly effect of the keys moving by themselves. The idea was that you could set this piano up in your lobby with a floppy full of Barry Manilow’s greatest hits, and your establishment would instantly be dripping with automated class.
Unfortunately, about a month or so back, the piano’s Disklavier DKC500RW control unit stopped reading disks. The piano itself still worked, but now required a human to do the playing. Calls were made, but as you might expect, most repair centers politely declined around the time they heard the word “floppy” and anyone who stayed on the line quoted a price that simply wasn’t economical.
Before they resorted to hiring a pianist, perhaps a rare example of a human taking a robot’s job, my brother asked if he could remove the control unit and see if I could make any sense of it. So with that, let’s dig into this vintage piece of musical equipment and see what a five figure price tag got you at the turn of the millennium.
You’d be forgiven for not realizing there’s still a diehard group of people out there carrying around dedicated MP3 players. While they were all the rage a decade or so back, most consumers have since moved over to using their handy dandy pocket supercomputer for playing their music. Plus controlling every other aspect of their personal life and finances, of course. Though that’s another story entirely.
But as [Conno Brooks] explained to us, there’s a sizable group of open source fanatics who prefer to store their jams on devices running the Rockbox firmware. Only problem is, some of the desirable Rockbox-compatible players are from the Golden Age of dedicated players, and aren’t getting any younger. In a recent blog post, he briefly goes over his ultimately successful attempt to put a new-made battery into his Sansa Clip+, a particularly desirable player that was released in 2009.
There are a few problems with the procedure that has kept it from being very widespread, according to [Conno]. For one, the Sansa Clip+ is tiny and not easily disassembled without destroying it. Worse, the diminutive 30mm x 36mm x 3mm OEM battery is effectively unobtainium. But ironically he was able to find an even smaller battery which seemed like it should work, assuming he could get it wired up.
The OEM battery on the Clip+ uses three wires, which [Conno] presumed was part of some thermal protection system. He first tried to take the circuit board off the original dead battery and graft it onto the modern cell, but something must have tripped because the resulting Franken-pack didn’t output any voltage. On his second attempt he simply ignored the third wire, and luckily the Clip+ didn’t seem to complain and started up as expected.
[Conno] says there’s some careful flexing required to get the new pack installed and the Clip+ closed properly, and the device’s runtime is somewhat diminished by the new battery’s lower capacity. But if it means another few years of keeping Big Brother out of your digital media habits, he figures it’s a worthy trade.
It can be disheartening when a favoured device begins to break-down. Afflicted by an all-but-dead battery and a fritzing-out hard drive, Redditor [cswimc] sensed the imminent doom creeping up on their 6th generation iPod, and responded by reviving and upgrading the decrepit device instead!
It’s no easy task to crack open one of these things, so they found themselves taking their time and carefully wedging the pry tool between the front and back covers, working their way around the exterior. Once separated, gingerly disconnecting the few ribbon cables allowed the iPod to be opened fully. From there, they turned to swapping out the original hard drive for an iFlash dual SD card board — one of the cards turned out to be a dud, but 128GB is still a step up from 80GB — and a new 3000mAh battery. Combined with replacing the power-hungry HDD, the battery life has been overwhelmingly increased over the original’s 650mAh capacity!
