Floppy disks turn out to be the greatest TV remote for kids

DrAwdeOccarim•1h ago
I love this! I really wanted to go down this road when my kids were younger, but the paucity of floppys and the low storage space made me go down the Avery business card print outs with RFID stickers on the back and a raspberry pi with an RFID reader inside. Of course, the author is using the floppys as hooks instead of as storage media...what a great idea. The tactile response and the art you can stick to them makes them ideal for this purpose.
ChicagoBoy11•59m ago
Did you build an enclosure for this?
vanderZwan•11m ago
I don't think I can get my hands on a floppy drive, but I still have an ancient computer somewhere with a DVD player in it. While not as cool, I had been considering turning into a simple media station for the specific purpose of letting my kid pick what music to play or video to watch by herself, without needing a screen to navigate it.

Like you, it never occurred to me that I can also just use specific DVDs or CDs as hooks for videos to be streamed, or media downloaded on a hard drive. So that suddenly makes the whole project a lot more interesting, and possibly easier too.

Buying a large pack of burnable DVDs is a lot cheaper and sustainable than using SD-cards like other commenters suggested.

SoftTalker•2m ago
QR codes on cards would work as well, if I'm understanding what this project is. The floppy disk approach has some nostalgia maybe but seems quite fragile. I quickly learned to never let my kids handle CDs/DVDs (one of the worst physical media designs ever; they are totally unprotected) as they would quickly become damaged and unplayable.
tete•1h ago
> Modern TVs are very poorly suited for kids. They require using complicated remotes or mobile phones, and navigating apps that continually try to lure you into watching something else than you intended to.

I'd argue that's not too different for grown-ups. ;)

bananaowl•1h ago
I witnessed my great aunt of 85 trying to watch TV. It was sad and painful. How ux is forgetting this entire generation is just terrible.
the_snooze•50m ago
UX is designed for shareholders first, not end-users.
RicoElectrico•49m ago
With my grandpa thankfully it wasn't as bad, though I had to regularly change back the source to HDMI (from STB). Somehow changing that himself was too much, even though he regularly read the teletext. Later, when choosing a new TV I opted for one that accepted a CAM module, obsoleting the cable STB. The simplicity of the remote was also a factor. So a cheap 32" Samsung TV it was. Turned out great. The other choice was a Sony, but my gut feeling about UI was right all along.
aquova•46m ago
To be fair, I remember visiting my aunt's house in the mid-2000s, who had a surround sound set up her husband had set up. It required three or four remotes to work and no one but him could ever get it working. I think UX has forgotten a few generations by now.
lou1306•36m ago
But that was the niche, "elite" experience. Today, a "smart TV" is the norm.

Has anybody ever been able to program a VCR ?
c22•5m ago
Although the trope is hilarious I think most people just don't bother since it doesn't matter to them. I never had a problem setting the time on my VCR and using it to automatically record shows while I was at work.
cheschire•41m ago
When my grandmother was in her late 70's, she couldn't figure out the concept of menus on DVDs, so she stuck with VHS well beyond the point others had let it go.

The capabilities of individuals over 70 are hugely varied. Some folks are clear-minded until 100, others start to lose their mental faculties much, much earlier.

I don't think the generation is forgotten, just so vastly different in needs from the core audience that it would require an entirely different solution, and likely an entirely different company model.

commandlinefan•24m ago
My father, before he passed away from Alzheimer's, couldn't do anything _except_ watch TV and I was so infuriated by how impossibly unusable they were for him. In the end, we just bought a DVD player and a mountain of physical DVD's (on the plus side, used ones are really easy to find cheap nowadays). I can't believe there's no option to just channel up and channel down a damned TV any more.
robinsonb5•15m ago
This, 100%.

I've seen the same scenario - someone with limited vision, next to no feeling in his fingertips and an inability to build a mental model of the menu system on the TV (or actually the digi-box, since this was immediately after the digital TV switchover).

Losing the simplicity of channel-up / down buttons was quite simply the end of his unsupervised access to television.

SoftTalker•8m ago
Channel up/down doesn't scale to the amount of content available now. It was OK when there were maybe half a dozen broadcast stations you could choose from.
c22•11m ago
When I was a kid I remember being amazed that my elderly grandmother couldn't operate the VCR. Among other things she was unfamiliar with the universal icons for 'play', 'pause', and 'stop'.
tantalor•47m ago
My biggest gripe is how terribly slow it is to navigate UI on a TV. The latency between user input and the UI responding can be upwards of 10-20 seconds. Just incredibly user hostile.
andrewblossom•34m ago
This can be solved by using any number of 3rd-party streaming devices: Apple TV, Google TV Streamer, NVIDIA Shield, ...

I've never experienced an TV OS that was reliably better than one of the above, though a Roku-OS TV came close.

mjparrott•31m ago
I tried to look for a 'dumb' tv for a long time to get to a setup like this. The ultimate setup would be 1) a totally dumb and stupid tv + 2) a streaming box like Apple TV or whatever. I just want the audio/visual aspect of the screen, nothing else.
walthamstow•24m ago
If you never connect it to the internet, all TVs are dumb. I have an airgapped Panasonic powered by Nvidia Shield for years.

The only issue I ever had was Google adding ads to the front page of the Android TV launcher. Easily fixed by using a different launcher.

wafflemaker•22m ago
Given enough determination, you can learn how to locate antennas in the TV and remove them, which would render the TV dumb for all intents and purposes.

I have no experience with it, it just might be less work to remove antennas from any TV than finding a dumb TV in 2026.

mikestew•19m ago
Or one could just, you know, not connect it to the Internet rather than ripping apart your new TV.
c22•14m ago
You can purchase commercial signage displays that are just dumb screens, but the markup is quite high. Easier to just get one of the 'smart' ones and never let it connect to the internet.
cc81•9m ago
You don't need to connect it to the Internet or use the built in OS for anything else than just navigate to your box. I just use my NVIDIA Shield for everything.
catlikesshrimp•17m ago

That sounds like you have an overly shitty ‘smart’ TV. Plenty of external devices (I’m partial to AppleTV) have no significant lag.

Or it could be you’re using some niche service that has its own issues.

no_wizard•6m ago
It’s a matter of time before tv manufacturers start requiring an app to sync with the TV to set it up.

That would let them glean information about you every time you use said app.

You’re still getting around this with a 3rd party device like an Apple TV for the most part but if it’s required to even turn it off or on it’ll be enough to sync any metadata that it holds

m4tthumphrey•11m ago
This is definitely due to the age/quality/model of the TV. I have 4 LG TVs across the house and the newest/biggest is 100x faster than the oldest.
dangus•7m ago
People say this after buying the cheapest $500 65” TV they can find or plugging in a $35 Roku.

You get what you pay for.

I’m honestly not even sure if consumer apathy is the fault of these mega corporations. They’re just giving people what they want.

They don’t want to pay a premium for TV (ads), they don’t want to pay $200 for a set top box (slow UI), they don’t want to pay for media per-use (declining blu-ray and digital purchase sales, death of the DVD rental/bargain bin market).

I have people in my life who have Amazon TVs all over their house and yell voice commands at them over and over while these cheap TVs are too slow to respond and they think it’s a good experience. People are dumb.

For nogstalgia's sake you can also a really old HDD and do some seeks (without doing anything of course) and make the HDD Led (installed on old drives) blink and make old school coffee machine sounds. This would make waiting even more "something is going to happen! ... I know it! ... just waiting to load ...".
voidUpdate•59m ago
I've been thinking of making something similar for my kodi setup for a while, possibly with NFC "disks", or SD card "cartridges", similar to this https://youtu.be/END_PVp3Eds, but I didn't think about using floppies. If I can get my hands on some, that could make a nice "physical library" too. Also a good tip about the arduino floppy drive library, I'll probably make use of that to debug my floppy drive to see if it's the problem or some configuration in my computer that isn't working
afandian•55m ago
I did this for my child with an ESP32, RFID cards off ebay, and MP3s on a SD card. A fun project.

Tip: it's much quicker to read the serial number of the RFID card and rename the MP3 than it is to program the MP3 name to the card!

The floppy disk insertion detection could take a cue from AmigaOS and try to read a track to see if it gets anything. But not sure if that would work without changing the floppy driver...

Wow, I think this is the first one of these "floppies for kids" things I've seen that actually stores something on the disk.
wffurr•49m ago
I love these physical mechanisms for controlling the software that surrounds us. Not enough physical UX out there; all the industrial designers seem to be in love with single button controls or touchscreens or capacitive panels. I presume they're cheaper than switches with a nice thunk or dials with a nice clicky feel.

Unfortunately, it takes a fair bit of time and skill with microelectronics and fabrication to build these things.

My 7 year old has figured out the Roku app pretty well and can play stuff on PBS Kids or turn on the Nintendo Switch without any guidance. His 3 year old brother, not so much.

Reminds me of HitClips from the early 2000s

I remember being quite entranced with one that a neighbor had. It feels like a bit of a silly format now, but perhaps it's time for a resurgence.

I am not sure physical component will help that much. Not after I once saw a kid swap between 4 different Minions DVDs every 5-10 minutes.

A few rfid stickers would have been easier :)

Does it play exactly one video?

didacusc•44m ago
Why not just burn DVDs with whatever content one wants to fetch and re-encode to SD MPEG2? It's not like kids are super critical about picture quality anyway.
herpdyderp•6m ago
DVDs are significantly more fragile
postalcoder•42m ago
I love these ideas. Another great implementation I've seen on here is someone using NFC/RFID chips to do something similar.

For my toddler, I've started the process of hooking up my TV with a Mac Mini, Broadlink RF dongle, and a Stream Deck. I'm using a python library to control the stream deck.

I'm configuring the buttons to play her favorite shows with jellyfin. End goal is to create a jukebox for her favorite shows/movies/music. Only thing I have it wired to do right now is play fart noises.

It almost feels like a Yoto player: https://us.yotoplay.com/
palmotea•42m ago
There are some off-the-shelf products that work similarly in the audio space:

https://us.yotoplay.com/

https://us.tonies.com/

I had plans to build something that for the TV, but having kids means I never had the time. And honestly, that might not have been such a bad thing since it made setting limits easier. I was able to teach my kid to turn the TV off when she was fairly young (and pause more recently), which seems to be enough.

My daughter has a yoto and it has been absolutely invaluable for self directed learning and entertainment (with boundaries). But idk floppy disk seems way cooler to me!
arscan•21m ago
We have a yoto for our son, and its a great experience, but be prepared for pricing of content to match what we used to page for cds/tapes. e.g., the pout-pout fish card is $8 USD for 10 minutes of content [1].

I think that's ok, as he actually would get a lot more than 10 minutes of use out of it, and its great to pay the creators while not having to worry about ads manipulating my kid. But it highlights how expectations for the pricing of audio/video content has changed (probably for the worse)... for me at least.

neutronicus•4m ago
We have a Yoto here as well, for our six-year-old.

The concept is great - RFID as a replacement for cassette audiobooks (with fewer storage limitations!).

I do wish it integrated better with sources of free audiobooks. The Libby app gets us access to a lot of audiobooks through the public library, many of which are not even available for purchase through the Yoto player. We can only use it to play them for him as a Bluetooth speaker from our phones, which removes a lot of the utility of the player (he can't navigate chapters, we can't set a sleep timer, we can't use our phones for other things).

The concept is great though and the specific product, walled content garden notwithstanding, has been a net win for us.

jimbobjim•1m ago
The blank cards they sell are great. We borrow audio books from the library and I rip them to a card, you can reuse them as well so don’t need to buy too many. I also put radio streams on them, like classical stations for when my sons going to bed.
johnyzee•41m ago
I loved the tactile feel of 3.5" floppies (especially coming from the - actually floppy - 5.25"s). Great choice. In particular, the spring-loaded metal shield was very satisfying to play with, unfortunately those are missing on the disks in the picture (apart from one, which seems to not have the closing spring)! Possibly a casualty to the three year old user.
ezconnect•31m ago
My 3 year old learned how to use the remote and watched by himself. We just instructed him not to watch silly stuff and he learned which show teaches him something and discovered numberblocks and alphablocks by himself on youtubekids. My other son just can't comprehend how to use the remote and learned it when he's already 4.5 years old. The main method they use for discovery is the speech search.

Responding to the title: Made me think of Star Trek TOS food synthesizers (the precursor to replicators). They used floppy-disk-like cards as their main interface: https://memory-alpha.fandom.com/wiki/Food_synthesizer?file=F...

In particular what brought it to mind was a scene in one episode with a bunch of kids being shown how it works, same episode as the page's title image.

My 3 year old watched TV for the first time for 2 minutes in her life (it was hard hiding it from her in an airplane on an overhead screen) and I can tell that TV is generally bad for kids at that age.
