Floppy Disk Sales Are Higher-Density Than You Might Think

Floppies may be big in Japan, but nostalgic and/or needful Stateside floppy enthusiasts needn’t fret — just use AOL keyword point that browser toward floppydisk.com. There, you can buy new floppies of all sizes, both new and old, recycle your disks, or send them in to get all that precious vintage stuff transferred off of them.

That delightfully Web 1.0 site is owned by Tom Persky, who fancies himself the ‘last man standing in the floppy disk business’. Who are we to argue? By the way, Tom has owned that address since approximately 1990 — evidently that’s when a cyber-squatter offered up the domain for $1,000, and although Tom scoffed at paying so much as $1 for any URL, his wife got the checkbook out, and he has had her to thank for it ever since.

My business, which used to be 90% CD and DVD duplication, is now 90% selling blank floppy disks. It’s shocking to me. — Tom Persky

In the course of writing a book all about yours-truly’s favorite less-than-rigid medium, authors Niek Hilkmann and Thomas Walskaar sat down to talk with Tom about what it’s like to basically sell buggy whips in the age of the electric car.

Tom also owns diskduper.com, which is where he got his start with floppies — by duplicating them. In the 80s and 90s, being in this business was a bit like cranking out legal tender in the basement. As time wore on and more companies stopped selling floppies or simply went under, the focus of Tom’s company shifted away from duplication and toward sales. Whereas the business was once 90% duplication and 10% floppy sales, in 2022, those percentages have flopped places, if you will.

Walkmp3rson Is An MP3 Player Like Sony Never Made

If you weren’t already well aware, the 90s are like, so hot right now, and that includes cassette tapes for some reason. (Even though we personally didn’t have a CD player until 1998, they were around as early as 1982.) But if you don’t dig the quality of cassettes, or if you’d just rather carry around more than 45-120 minutes worth of music, than [John Edgar Park]’s Walkmp3rson is definitely the build for you. That’s pronounced ‘Walkperson’, as in a 21st century MP3-based update of the classic Walkman.

Inside this amazing 3D printed enclosure, you’ll find an Adafruit Feather RP2040 controlling the screen, handling input from the rotary encoder and those sweet mechanical keyswitches, and of course, playing audio files from SD cards through the amplifier breakout board. And no, this isn’t just another MP3 player — well, it kind of is, but the presentation really goes a long way here.

There are tons of retro-modern nods, like the cassette reel animation that plays on the TFT screen, the boxy enclosure, and the fact it involves physical media. Oh yes — you get to insert an SD card whenever you want to change albums/discographies/genres/whatever. In fact, this would be a great use of older, smaller SD cards. You could go all out and make tiny album art to slip inside those milky plastic cases. Check out the brief demo video after the break.

Looking to play your tunes on a microcontroller, but not a fan of the Walkman aesthetic? In June we covered a similar audio player powered by the ESP32 that does an uncanny impersonation of a portable tape deck that you might be interested in.

Banana Split Macropad Is Dessert For Your Desk

Once again, [Dan Bostian] is ahead of the curve when it comes to bringing bunches of banana puns to the table, but we think you’ll find this banana split macropad quite appealing nonetheless. Does this tasty thing look familiar? It ought to — we discovered, plucked, and uncovered the one-piece version last summer, and this time, [Dan] simply made our two-piece, wireless dreams come true.
Peel back the — oh, forget it. Inside, you’ll find a nice!nano running the show from the right-hand board using ZMK firmware, and a banana-shaped chalk outline on the left-hand silkscreen that represents how completely [Dan] killed it with this build. You can use any switches you want, as long as they’re Cherry MX-compatible in the shoe footprint department.
The PCBs are open source, of course, and so are the printed parts — it’s all there in the repo. As for the stickers, well, you’ll have to produce those yourself.

Keebin’ With Kristina: The One With The Hexagonal Keyboard

Well, I didn’t mean to take the whole summer off from Keebin’, it just kind of happened that way. You’d think it would have been #13 that tripped me up, but we ain’t even there yet — this is only the twelfth edition. I kept thinking I should write one and it just wasn’t happening, until I got a tip from [s.ol bekic] about their stunning hexagonal keycaps and the journey toward making an open-source 12-key macropad featuring same.

But let’s back up a bit. Originally, [s.ol] designed a totally sick hybrid MIDI-and-typing keyboard from scratch, which you can see in this short video. It glows, it splits in half, and it snaps back together again quite satisfyingly. And you probably noticed the hexagonal keycaps that look like they might be printed or milled, or perhaps even printed and then milled.

In actuality, [s.ol] threw all the processes at this keycap project — milling, molding and casting, and 3D printing. None of them worked well enough to get much past the prototype stage, but in the end, [s.ol] joined forces with fkcaps.com to create and offer an injection-molded version that I’d really, really like to rock my fingertips around in. Good thing I can pick some up for cheap.

Of course, the real process was all the learning [s.ol] did along the way — both in the early days of making the hybrid keyboard, and after teaming up with fkcaps to make the keycaps and the accompanying macropad into real products. And that was after all the design work it took to get this newfangled honeycomb configuration right.

In case you’re wondering, these are meant for only Kailh chocs, but no matter the switch, the spacing is really important because of all the possible points of friction introduced by the design. Be sure to check out the keycap docs page, macropad docs page, and this gallery of keycaps and macropads.

Hackaday Links: September 11, 2022

Good news out of Mars from the little lunchbox that could — in the seven times that MOXIE has run since it arrived in February 2021, it has reached its target production of six grams of oxygen per hour, which is in line with the output of a modest tree here on Earth. The research team which includes MOXIE engineers report that although the solid oxide electrolysis machine has shown it can produce oxygen at almost any time or day of the Martian scale, they have not shown what MOXIE can do at dawn or dusk, when the temperature changes are substantial, but they say they have ‘an ace up (their) sleeve’ that will let them do that. We can’t wait to see what they mean.

In other, somewhat funnier space news — early last Sunday morning, the ESA’s Solar Orbiter was cruising by Venus as part of a gravity-assist maneuver to get the Orbiter closer to the Sun. Two days before the Orbiter was to reach its closest point to the spacious star, it spat a coronal mass ejection in the general direction of both Venus and the Orbiter (dibs on that band name), as if to say ‘boo’. Fortunately, the spacecraft is designed to withstand such slights, but the same cannot be said for Venus — these events have their way with Venus’ atmosphere, depleting it of gasses.

Hackaday Podcast 184: What Is Art, Bulk Tape Eraser Go Brr, And The Death Of Email

This week, Editor-in-Chief Elliot Williams and Assignments Editor Kristina Panos had a lot of fun discussing the best of the previous week’s hacks in spite of Elliot’s microphone connectivity troubles. News-wise, we busted out the wine and cheese to briefly debate whether a Colorado man should have won an art competition by entering an image created by AI. Afterward, we went around a bit about floppies, which are being outlawed in Japan.

Then it’s on to the What’s That Sound Results Show, but since Elliot can’t find a 14-sided die, he pulled on the Internet for our random number needs. Congratulations to our big winner [D Rex], who will receive one our coveted Hackaday Podcast t-shirts (Ed. note: Heck, I don’t even have one! That’s how special these babies are).

Is the food-safety-of-3D-printing debate over once and for all? It is as far as Elliot’s concerned. You know what else is over? The era of distributed, independent email servers. Bah! We’re not kidding about that last one — and we discuss a lie-detecting app that may or may not prove our innocence.

Finally, we talk active foot cooling, heat barriers for hot shops, and big, strong magnets. What are they for? Fixing floppies, fool!
