Still this thing, 20 years on:

Kinda true, how this thing even worked, nobody knows

[–] tibi@lemmy.world 31 points 1 month ago* (last edited 1 month ago)

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.

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?

[–] bizarroland@fedia.io 35 points 1 month ago (1 children)

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 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.

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.

Probably a cheap 3D printer

[–] ArmoredCavalry@lemmy.world 14 points 1 month ago (7 children)

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.

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.

[–] shinratdr@lemmy.ca 10 points 1 month ago

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.

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.

[–] JustEnoughDucks@feddit.nl 14 points 1 month ago (1 children)

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.

[–] GrammarPolice@lemmy.world 7 points 1 month ago (1 children)

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.

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).

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.

[–] tibi@lemmy.world 6 points 1 month ago (1 children)

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.

[–] TehWorld@lemmy.world 6 points 1 month ago (1 children)

Does web browsing count as a “basic” task these days?

An R36s is like 40 bucks, and can emulate a LOT of old game consoles. I think that's pretty neat

[–] ArmoredCavalry@lemmy.world 8 points 1 month ago

That's a good example! I have a RG35XX, and definitely fun to see how far gaming tech has come.

I once found a curved 4k monitor at my local thrift shop for $70.

[–] Tja@programming.dev 15 points 1 month ago (1 children)

While "good for you" and "congrats", it's not something anyone can buy for under 100 bucks.

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

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 is “futuristic” in this context?

A calculator is pretty futuristic depending on where you start

[–] ArmoredCavalry@lemmy.world 11 points 1 month ago

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 Voxellab Aquilla FDM printer. They're regularly on sale for about $70. Maybe cheaper these days since they're kind old now.
