Still this thing, 20 years on:
Kinda true, how this thing even worked, nobody knows
The tape head is basically a small and really sensitive electromagnet. Magnetized tape creates small disturbances in the magnetic signal. Amplify those disturbances and you get sound. Similar to an antenna, but only works in close proximity.
This also works in reverse. Feed an audio signal through the electromagnet, and the electromagnet will create the disturbances in whatever is next to it. You can do this to record to a tape, or you can do this to pass sound to another tape head, which is how these aux cassettes work.
You can build one yourself really easily. Just take the tape head from a broken player and solder to an aux cable. Take a cassette, remove the tape, and put the tape head in the middle portion so it comes into contact with the player tape head.
Of course it’s Technology Connections. Who else would make a video about a (now) useless piece of 80’s tech with enough content to satisfy any level of curiosity.
I think of it as extremely 00s. It’s the “I only have an mp3 player/phone and my computer doesn’t take aux” device
If you shop around you can find a Brother (B&W) laser printer for about $100.
Imagine this weird future: Printers that always just work no matter what type of computer you have or how long they’ve sat since you last used them. And the “ink” cartridges last forever. And you can buy 3rd party refills or even refill them yourself. Plus it’s completely reliant on microplastics to do its job, what’s more futuristic than that?
Even better, if you scour your local thrift stores you can occasionally find them for as little as $10 and all they typically need is a cleanup and a new toner cartridge.
I bought mine for $7 4 years ago and it’s still working on the toner cartridge that was in the printer when I bought it.
Admittedly, I only print about 40 or 50 pages a year but that’s a hell of a deal.
so wish I had bought my brother laser earlier.

I lived in the 90’s, when office work was a tad more reliant on printers and late stage capitalism wasn’t as bad. My dad had a laser printer for his business. Very reliable, fast, never needed anything.
I remember that as the past, is my point.
I was thinking this too, but consider some improvements:
- wireless printing seems to “just work” now. Besides having to painfully enter my wifi password with up and down arrows on my printer, it seems like my windows and Mac laptops are able to print to it wirelessly without any initial setup. (I use Linux on my desktop but haven’t tried printing from it yet). I think it even works from phones.
- cables: I don’t remember what type of cable printers used, but I remember the big keyboard cable, then the smaller purple and green PS/2 ones (I think keyboard and mouse were different?)… I vaguely remember multiple different peripheral cables, like FireWire? Giant parallel ports for things like scanners?
I hate that most printers don’t come with the USB (B?) cable that seemingly only printers need now, but I’m glad that it’s standard and that everything supports
<strikethrough>USB-A</strikethrough>I mean USB-C (except my PC) now. Such a utopia.
I’ve got one of those and I’m pretty sure I’ve been using the same toner cartridge for like a dozen years.
A bow drill fire starter.
…I suppose it depends on what you assume the future will be like…
Barring that, you can get some small vials of tritium gas for under that price.
What would one do with small vials of tritium gas?
Not much really. Looks cool though. I suppose it’s more of a decoration than “tech.” About the only practical application of it is a tool to terrify the uneducated. The quantities of tritium the average person can buy are beyond harmless. You could breathe a hundred vials of the stuff and be completely unaffected. If you drank nothing but tritium water for several weeks, you would have some issues. But tiny vials with micrograms of tritium vapor inside? Utterly harmless.
Or, I suppose for the criminally minded, you could find some evil uses for it. You could probably rob a bank with it. “Give me all the money or I break this vial of radioactive vapor!” That would probably get you a wikipedia page, if you’re just dying for your 5 minutes of fame. You could go down in history as, “that mad scientist that robbed a bank using radioactive gas.” Of course it would be a bluff.
Though if you’re just going to bluff your way through bank robbery, you can just stick your hand in a hoodie pocket for the same effect.
I suppose you could use it for other similar criminal acts of varied nobility. You could probably use the same bluff to create a hostage situation to bring awareness to whatever political/religious cause is your cup of tea. Ultimately most people are very ignorant of nuclear science, and simply the words “radioactive tritium” would cause people to shit themselves. And that fear could be harnessed for all sorts of malevolent purposes. (Even better as you can actually show people the faint glow from it, and prove that you do have something radioactive.)
Hmm… what else could you use tritium for? I suppose you could use it for religious purposes. Absolute quantities really don’t matter much for that.
What else? You could tie it to a keychain and be able to find your keys in a dark room.
But really, it’s mostly a novelty. I think small amounts of it can be used for gun sights. But in any quantity the average person could afford or legally be allowed to purchase, it’s a harmless novelty. Larger quantities can be used in fusion reactor experiments and nuclear weapons. But if you try to acquire that much, you better have a budget in the millions, and the NRC is going to be on your ass. The average person can get a small vial of it that faintly glows blue in a dark room. It looks cool embedded in jewelry, but it really doesn’t have much practical purposes beyond perhaps terrifying the ignorant. But I really don’t consider malevolent uses to be truly practical applications.
(In case it isn’t obvious, I do not endorse using radioactive tritium in the commission of any crime or act of violence or threat of violence.)
Lmao I love that this became a thought exercise on the nefarious uses of tritium. Thanks for the info! I’ll keep all of these in mind when trying to determine what to do with my newly acquired tritium. >=)
^^^ Umm, FBI, if you’re reading, it was all their idea! ^^^^
°_°
I have a little tritium vial on my keys because I am a clumsy oaf with ADHD and the little greeny glow has been useful a couple of times. It’s great when I’m out at night and my keys yeet themselves out of my pocket and land in the darkest possible area.
I mostly got it because it’s cool though. Radioluminescence is fukken rad!
I’ve wanted one of these for decades but I thought they weren’t legal to purchase in my country anymore. I’m living vicariously through you.
Based off of your comment history, it seeeeems like you live in the US, although I could deffo be wrong. That’s where I live, so I may have good news. It’s illegal to sell tritium products in the US, but it’s not illegal to buy it as an individual. There’s a Taiwanese company that sells all kinds of cool little tritium widgets: https://www.mixglo.com/
that’s where I got my vial from. It wasn’t cheap for what it is, but I think it’s cool.
edit: looks like they also ship to Canada if you live there. I’ve no idea what the laws are up there, but I’m assuming it’s legal if they’re willing to ship.
How many vials of tritium do I need until my bluff in the bank lobby is no longer an empty threat?
Umm, contact (202) 324-3000 and ask them. They’ll know for sure.
A 1-terabyte MicroSD card
For under 100$ ?
Yeah, as low as $61 on Amazon for 1TB. Pretty amazing if you’re old like me and remember diskettes.
Those can’t be real
Most of the ones on Amazon aren’t trustworthy. Especially at high capacities. But apparently you can get up to 2TB now, at least in theory. I imagine the support for them is pretty limited though still.
Official “support” just means the biggest size they tested. The current SDXC standard has supported up to 2TB since the standard was released. Any device supporting SDXC should work just fine with a 2TB card even if they don’t specify it as officially supported (assuming they didn’t deliberately nerf their driver for some unfathomable reason).
I bought a large capacity unknown brand cheap SD card somewhat recently, it seemed real at first but after installing an OS on it and running a few minutes became bricked somehow. At least I got a refund.
In the uk I can get 1TB for 95gbp from sandisk website.
So probably less than 100 usd in usa from a reputable seller.
I bought a 512 GB SanDisk one for $65 USD a few years ago. I don’t like Samsung software bloatware on their phones, but having 512 GB of storage for $65 feels pretty futuristic to me. I can’t believe more phone manufacturers don’t offer external SD card support… you’d think more consumers would demand it, given that the alternative is to pay a lot more, every time you get a new phone.
I’m basically able to keep like every photo I’ve taken for the last 10 years or so (though not at original resolution).
They’re sold as 1TB for that price. But if you actually write that much, you’ll find that only part of your data is there. The rest is garbled or zero.
There’s tools to restore this (on windows/linux), and it’ll show up as a smaller size when you run them. You can also use such tools to set any fake size you like
$61?!?!?
Bro. $12 at Microcenter.
Amazon is doing you dirty.
$12 for a 1TB MicroSD card? Are you living in the future? :P
I am now!
Yep https://www.amazon.com/SAMSUNG-microSD-MicroSDXC-MB-MD1T0SA-AM/dp/B0CWPNS8JY $99.99 it shows for me - not sure how taxes work on this (I’m not American) but that probably counts.

Probably a cheap 3D printer
I’m actually blown away by how good of a 3D Printer you can get for ~$200 now. Huge improvement from just a few years ago.
I got an ender 3 pro for about $100 a couple years ago
I started off on an Ender 3 V2 a few years back. The AnkerMake M5C and Bambu A1 Mini are both down to $199 and can’t believe how much faster / more reliable they are for the price.
this entirely. It’s awesome and frustrating haha. My Neptune 3 from 2022, that I’ve poured hundreds of dollars and hours into, is completely outclassed by an out-of-the-box printer of the same or lower price today.
I’m really happy that it’s getting so approachable now, I hope that I can get my grandfather his own printer during his time. I love that you don’t need to be an engineer anymore to get the things to work.
I wish my grandad had made it long enough to have had a 3D printer, he would have absolutely loved it (he died in his 90’s, so he did alright).
Hey, he got to see the invention of plastic. Obviously we’re dealing with the repercussions of it now, but imagine what that must’ve done to the hobby industry.
True (E: actually not quite, he was born a little after plastic was invented), and he loved laminating shit lol though he was more in to metal work. But later in life he really got in to computers, which is why I think 3D printing would have been right up his ally, because he could use the computer to make things he might no longer have been able to with his hands, and then get to play around with all of his creations (and gift us grandkids an endless supply of things lol)…
A full working computer, more powerful than what we used to go to the moon, and using less power than a light bulb.
It can take many forms, like smartphones, SBCs or older PCs/laptops.
You can buy an ESP board that meets all those qualifications from AliExpress for less than $3CAD shipped.
Setting one of those up was the first time in a while I’ve been so impressed with just how cheap and accessible tech has gotten. It’s a web server with WiFi and Bluetooth shipped to my door all for the price of a chocolate bar.
or mini pcs
By that logic, a lighter. Better than smashing two rocks together, that’s how we used to make fire.
One of those fancy plasma lighters, sure. But butane lighters have been around for decades
A knife. Futuristic in that it will be handy for hunting and self-defense after the future collapse of civilization that results from our insatiable appetite for consumption - of, among other things, useless gadgets.
I feel like that really depends on how you view futuristic.
I think things with colored e-ink displays, USB C chargeable AA batteries, handheld emulators, 2230 NVMe drives, and USB C power portable displays are really cool but I feel like their availability these days has made them lose a bit of their futuristic luster. They would have blown my mind when I was a kid.
More niche products like Meshtastic and ESP32 Marauder devices are things I view as futuristic (and can be found for under $100).
I think this is really the best answer. The future is decentralisation, to me. Stuff like meshtastic could take the best parts of the internet and make it local and community owned.
In fact, I think there are a bunch of things you can get for free which to me represent the future. Linux, Lemmy, FOSS in general. Physical technology is only a small part of the puzzle nowadays.
Yeah I feel like having control over the things you use is definitely a big part. Something that really hampers my enthusiasm for AI is that so much of it is out of my control and generally disconnected from me.
Having AI that I can modify and run locally on my devices seems a lot more sci-fi than something that can relies so heavily on the Internet and rigid responses.
Absolutely! Running local LLMs is way more exciting than something I need to figure out an API and billing for. Tedious corporate bullshit? No thank you. A robot that I have trained to enthusiastically denounce capitalism? That’s more like it!
Hell yeah. I tried to train one to feed me misinformation and encourage bad habits like drinking and driving and it was a lot more fun and lively than anything else I’ve seen
I once found a curved 4k monitor at my local thrift shop for $70.
While “good for you” and “congrats”, it’s not something anyone can buy for under 100 bucks.
That specific monitor? No. But I often see things second-hand that are under $100 and could be considered “futuristic tech”.
If you know where to look and are patient there are good deals to be had.
Raspberry Pis and other microcomputers can be had for pretty cheap, and they can be put to a surprising variety of tasks. You need to be a bit of a jack of all trades to fully embrace that DIY element, but I’d bet that showing off a project that you mostly built yourself would be seen as futuristic by most people.
The RPI400 is basically a full solution. You just need a display and a mouse, and you have a fully functional desktop computer. Not very powerful, but good enough for basic tasks like writing documents or browsing the web, coding etc.
Does web browsing count as a “basic” task these days?
I think it does so for nearly two decades
An R36s is like 40 bucks, and can emulate a LOT of old game consoles. I think that’s pretty neat
That’s a good example! I have a RG35XX, and definitely fun to see how far gaming tech has come.
Where can you get one and does it take a lot of work to set up?
Looks like they sell them on Amazon and some .UK site but I only see them for $65
We got ours off Aliexpress (pretty sure all other sites are just dropshipped from there anyway)
Technically they come with the full OS and all the games preloaded, but their SD cards are very shoddy and you run the risk of losing all your data if you use those
Setting up a fresh SD Card took my husband about an hour for both of our consoles, so I guess it wasn’t too tricky
Ali express (like Chinese Amazon, mostly direct from factories I think).
They are always “on sale”, but the prices are usually 30-50 bucks.
Here’s an example: https://a.aliexpress.com/_mOcxZJq they come with thousands of games that for the most pretty just work. It a game doesn’t emulate well, like mario64 didn’t for me, I don’t know what you can do about it.
Get the r36S - the S is faster or something.
Sam with miyoo mini plus. Great time to get into emulation machines.
For an extra 20, you can put Gulikit hall effect joycon sticks in it. And for a few dollars more, there’s a spot on the board to solder and mount a haptic feedback motor. Still under $100. You want to get extra crazy, you could fit a small usb wireless adapter inside it. Still trying to figure out how to get stereo sound. But at the point of all those mods, you could get an RG35XX.
Devices less sophisticated than smart phones were once pretty common in sci-fi novels, but they still achieved the same sort of thing, all the world’s knowledge in the palm of your hand.
You can get smartphones for absurdly cheap these days, and while crappy by modern standards they’re still technological marvels.
lighters. fire on demand! for all of preindustrial human history these things would be worth more than gold
I think the deauther watch is pretty cool if we’re thinking cyberpunk-esque
I’m not sure what that’s for but it looks cool as hell
Deauther is generally used for kicking clients off WiFi networks.
You can setup a mirror network, kick clients off the real one, they’ll try to reconnect to yours, by which you can steal the WiFi credentials, or even listen in on the traffic.
Or just for testing, obviously.
