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.
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.
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.
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.
It's interesting the difference in what people think a collapsed civilization will look like.
Some people think we will "return to monke" where wilderness survival skills will be essential and people who have them will be the "main characters." That would probably be the easier and better future.
The more likely option will be technofeudalism where rich people have small, brutal armies and control localized power grids, farming operations, and politics with tech as mass migrations happen and wildlife becomes all but extinct outside of human cultivation. Survival skills won't matter when all land and food scarcity is controlled by a rich few with absolute control. The average survivalist will be wiped out with the first natural disaster or by the feudal lords with drones. Return to nature might only come after 50 years when chip supplies and power grids have dried up and fallen apart, but it would just as likely be mad-max as oil could likely still be used.
Who knows. Fascism might take over with how it is going now and solve the climate crisis with mass genocide and forcing green energy for all we know.
I see you've read Yanis Varoufakis. In all realism though, a fallen society is most likely to be a result of climate change. First it gets too hot for Africans, so their only option is to move northward and eastward to the Middle East. This results in tightened borders and the death of many due to heatstroke and dehydration - I also don't doubt a slave trade-like and human exploitation era might come about because of this. Increased demand for AC's in the west will also be a byproduct of this. Melting ice caps will also increase the danger to many of those living in coastal regions - Florida probably sinks faster than we'd predicted.
All of this I project to happen within the next 50 years where the problems are left for Gen Z and further generations to deal with.
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?

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 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.
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.
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.
The thing about meshtastic is the walking distance range and limitation to text messages.
Though I don't know if it is possible to integrate a LoRAWAN concentrator with a nice collinear J-pole antenna to mount on the top of your house to move to a double digit range where it could be useful as a neighborhood mesh with multiple channels. (With the added benefit of using lorawan devices like pet trackers and things).
Still Lora smart (but local) home agriculture, water collection, etc... Is a really cool technology for large properties.
I find it's a lot of those ideal use cases I find futuristic. The RISC V architecture and Briar are kind of similar. They're really neat and I could see some cyberpunk style uses for them but the drive for their adoption and the level of it just doesn't seem to be there yet.
There was a TV show. Stephen Fry 100 greatest gadgets.
For 1 he told a story about how some guy was talking to a largely uncontacted tribe and they were really interested in their tech.
So he knew they would have a supply drop and took them out to see the plane for the first time ever. The tribe was remarkable unimpressed with the sight.
The guy asked what was up and they came back with the reply "You can make fire from your fingertips. Of course you can fly"
I suppose it really depends on your perspective. If you're that uncontacted tribe, you see birds all the time. The idea of a creature being able to fly is pretty mundane. Humans can't naturally fly like birds, but neither can they naturally wield knives as long and sharp as tiger claws. But flying is ultimately just duplicating something already found in nature.
But the ability to instantly and effortlessly summon fire? The closest thing in nature is the bombardier beetle, and that shoots boiling acid. Impressive, but it's not true fire. There are no creatures in nature that can just summon fire on command. From a natural perspective, instantly creating fire is a lot more impressive than a flying machine.
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.)
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.
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.
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
You can buy a cheap smartwatch that will monitor your pulse, give you a pulse oximeter reading, handle text messages and phone calls, take photos, and also within a reasonable margin of error check your blood sugar for about $35 on AliExpress.
What do you mean with that? Depending on the recency of your device they can be quite accurate. I use a Garmin though because they last longer on battery and are a bit more oriented towards sports and health. Some studies I found back then suggested Garmin is not that far off lab testing on most metrics. Yes even the guestimated ones like vo2max.
I was thinking of something that would be considered futuristic to an average person today. So, maybe something uncommon, with impressive capabilities, but still affordable?
Not sure if many items fit that criteria, but was curious if any!
A basic DNA test can tell you your ancestry back thousands of years and identify numerous genetically determined traits. It's kinda crazy what kinds of things they can tell you about yourself.
And if you send in your dna three times, you can find all three if your ancestries!
Really tho, there was some funny news on this a while back when identical twins took those tests and got different results
