The Floppy Disk As A Portable Music Format

September 7, 2020 by Jenny List 27 Comments

We remember the floppy disk as the storage medium most of us used two decades or more ago, limited in capacity and susceptible to data loss. It found its way into a few unexpected uses such as Sony’s Mavica line of digital cameras, but outside those who maintain and use older equipment it’s now ancient history.

Seemingly not for [Terence Eden] though, who has made a portable audio player that uses a floppy disk as its storage medium. It came about with the realization that half an hour of extremely compressed audio could be squeezed onto a standard 3.5 inch floppy, and then that the Beatles’ A Hard Day’s Night album comes in at only a shade over that time. With some nifty manipulation of the compression command line and the judicious removal of some unnecessary metadata, the album can fit on a floppy in equivalent quality to the AM radio fans would have heard it over back in 1964.

The player would have been a major undertaking when the floppy was king, but in 2020 it’s simply a USB floppy drive, a Raspberry Pi, and a battery pack. He’s given us the full instructions, and no doubt a more permanent version could be built with a 3D-printed case.

We’re fascinated by the recent trend of storing audio on floppy disks, but despite the hipster vibe, we doubt the idea will catch on. It’s not the first floppy-based player we’ve seen, but the previous one was more of a fake player.

Music Player Erected From Floppy Disks

Holding on to a cache of old floppies because nostalgia? Us too, and this might be the coolest possible use for ’em. While it’s fun to imagine that he wrote a compression algorithm to fit a lossless copy of Coltrane’s Blue Train on a 1.44Mb coaster, or somehow rolled his own mini-disc, [Dino Fizzotti]’s Diskplayer uses floppies to serve up Spotify albums.

What’s actually on the floppy, then? The corresponding Spotify album URL. He just pops a disk in the drive, and the Pi does the rest — it detects the floppy event and executes a script that starts an open-source Spotify client. There’s no track skipping and no shuffle, just the entire album as intended, take it or eject it. If you think about it, he’s actually managed to improve on the vinyl experience, since all the songs are on one side. Demo is queued up after the break, and it includes [Dino]’s simple web interface for writing the Spoti-floppies.

When this project started seven months ago, [Dino] intended to bring his vinyl collection into the 21st century with RFID tags, but we’re glad that he decided to involve a fairly obsolete medium. Don’t have a drive or a heap of floppies gathering dust in a closet? Neither did [Dino]. But he found plenty of people selling pretty-colored floppies on ebay, and Amazon has tons of cheap external drives. We think the album art stickers are a nice touch, as is matching album cover color to floppy. He’s right to lock those bad boys up.

Got a bunch of floppy drives? Build a Floppotron and make your own music!

Retrotechtacular: The Floppy Disk Orphaned By Linux

July 26, 2019 by Jenny List 105 Comments

About a week ago, Linus Torvalds made a software commit which has an air about it of the end of an era. The code in question contains a few patches to the driver for native floppy disc controllers. What makes it worthy of note is that he remarks that the floppy driver is now orphaned. Its maintainer no longer has working floppy hardware upon which to test the software, and Linus remarks that “I think the driver can be considered pretty much dead from an actual hardware standpoint“, though he does point out that active support remains for USB floppy drives.

It’s a very reasonable view to have arrived at because outside the realm of retrocomputing the physical rather than virtual floppy disk has all but disappeared. It’s well over a decade since they ceased to be fitted to desktop and laptop computers, and where once they were a staple of any office they now exist only in the “save” icon on your wordprocessor. The floppy is dead, and has been for a long time.

The save icon in LibreOffice and other desktop software is probably the last place the floppy exerts a hold over us.

Still, Linus’ quiet announcement comes as a minor jolt to anyone of A Certain Age for whom the floppy disk and the computer were once inseparable. When your digital life resided not in your phone or on the cloud but in a plastic box of floppies, those disks meant something. There was a social impact to the floppy as well as a technological one, they were a physical token that could contain your treasured ephemeral possessions, a modern-day keepsake locket for the digital age. We may have stopped using them over a decade ago, but somehow they are still a part of our computing DNA.

So while for some of you the Retrotechtacular series is about rare and unusual technology from years past, it’s time to take a look at something ubiquitous that we all think we know. Where did the floppy disk come from, where is it still with us, and aside from that save icon what legacies has it bestowed upon us?

Read Amiga Floppies Using An Arduino

July 21, 2017 by Jenny List 21 Comments

So you spent your youth learning your craft in front of an Amiga 500+, but a quarter century later all you have left is a broken computer and a pile of floppies you can’t read any more. What’s to be done? This was the position [Rob Smith] found himself in, and since some of the commercial solutions to ripping Amiga floppies were rather expensive, he decided to have a go at making his own.

His write-up makes for a fascinating read, as he delves into the physical interface of the PC floppy drive he used, and into the timing required from the Arduino that controlled it. He faced some challenges in getting his code to be fast enough for the task, and goes into some of the optimisation techniques he employed. His code for both Arduino and Windows is open-source, and can be downloaded from his GitHub repository. Future plans involve supporting the FDI disc format as well as ADF, and adding the ability to write discs.

We’ve shown you a lot of Amigas over the years, but perhaps of most relevance here in our archive are this Raspberry Pi floppy emulator and this floppy autoloader for archiving a disc collection.

Plastic Cutter Made Of 3.5” Floppy Disk

June 11, 2016 by Anool Mahidharia 20 Comments

This is so cool; an unexpected use for an antiquated digital storage medium. [DeepSOIC] built a cutter that shaves off plastics but cannot cut through metal. It’s made out of the media part of a 3.5” floppy disk. For the new kids, here’s what a Floppy Disk is.

The disk is attached to any high speed DC motor connected to a plain ol’ power supply – variable if you want to adjust speed. As you can see from the video after the break, it cuts through plastic quite well, but is unable to damage any metal that it encounters. This property makes it extremely handy for many applications. Want to strip through an old 3.5mm phono jack without damaging the wires? Want to wind a coil over a plastic former and then strip away the plastic? Want to trim some 3D printed parts? All game for this handy tool. According to [DeepSOIC], if you don’t have floppy disks, you can use other kinds of plastic films too – such as overhead transparencies or plastic printer films. If you are in a pinch, he claims even paper works, although it doesn’t last too long. Don’t throw away all of those business cards yet.

This isn’t the only trick up his sleeve. He’s documenting a whole series on his project page at Hacks and Tricks. And if you like these, then also checkout [RoGeorge]’s bag of tricks over at The Devil is in the Details.
