Tape drives. Remember those big reels of tape on mainframes in the 80s? They don’t look exactly like that anymore, but tape is still used for backups/long term archival because they offer the lowest cost per gigabyte and decent longevity without needing to be powered, as long as you don’t need to access the data all that fast or often.
Those dank memes and cat videos you posted in 2010 are probably on tape in a data centre somewhere
Im obsessed with tape storage, but for audio. Nothing more real than audio on tape! Luckily it’s catching on again. Music is so disposable now, I hope we can keep physical formats alive and keep corporations away from it (digital offers them unlimited control over us).
Can you drop some tape player recs to save me on tape spaghetti?
Oh sorry, I meant more reel tape not really casettes, but I love the otari mx5050, and the teac 2340sx. Good machines and 1/4" tape is still affordable. PM me if you’d like more tape info, I love to share.
Ah okay haha. Ive been buying vinyls lately and there’s a lot of people with casette merch too. I didnt remember tape being that amazing but was willing to give it a shot. I don’t have reel to reel space at my place unfortunately. Thanks for putting it out there though!
Well I’ll say cassette quality can never really be good becaise of the slow speed and narrow width. . But 1/4" tape is about the best analog quality you can get (feasibly cost wise) if you go 15 IPS and half track (1 way play, no flipping).
If you want good sound for cassettes you can’t beat a Nakamichi deck, best there are.
Tape itself is cheap, but buying the other equipment for it costs a fortune.

Pretty much anything in a machine shop made in the last 80 years or so. So many people turn up their noses at anything that isn’t computer controlled anymore. Yknow what a big old mill can do that a CNC can’t? It can make every single part needed to make a new mill. It’s a self replicating machine with the right know how. People don’t respect that kind of quality anymore.
Can a CNC not do that for just the mechanical parts?
(I know way too much about bootstrapping semiconductor production at small scale, which seems to be viable but highly impractical)
Sure, but it’s not as impressive (imo) when you also need a computer control system, a bunch of circuitry and electronics, and a whole mess of software to make it work in the end. A mill just needs enough spin and it runs exactly as intended.
Oh yeah, I have a copy of the Gingery books and I love it.
I haven’t seen Gingery into how much power you need exactly, or what blend of RPM vs. torque is ideal. What would be your guess, since it sounds like you might know?
Torque is the real limiting factor. You can always gear up or down for whatever you’re working on, but at the end of the day you need enough torque to get the work done. And a proper milling machine needs A LOT of torque.
Can you give me some typical values, maybe? That would be a big help.
There are no “typical values” when you’re running a mill or lathe. You could look up “speeds and feeds”, but that’s really just a table that you plug into an equation to figure out how to set the machine. It all depends on what you’re doing and what you’re doing it with. Drilling a hole with a high speed steel drill bit is going to be a bit different than drilling it with a carbide spade, and all that is going to depend heavily on whether you’re trying to run through titanium or tin. You need to fine tune running “x” bit through “y” material for a “z” sized cut.
Essentially, this is the knowledge that separates skilled labor from manual labor, and machining is (was, RIP cnc button pushers) skilled labor.
At the end of the day for most metal machining you’ll need between 50hp and 100hp to be up to modern standards. If you want to get that through steam or electric motors or whatever that’s up to you
Thanks, that’s really helpful. I suppose it makes sense that not just material but cut size and bit would matter. They usually focus just on the geometry on YouTube.
Out of curiosity, what’s the lowest you’ve ever gone? It’s hard to picture machining happening at something like 60RPM.
If you want to get that through steam or electric motors or whatever that’s up to you
Since I’m interested in technological bootstrapping more generally, I think most about water wheels, actually! Steam engines need to be machined, which is a chicken-and-egg problem (or I guess crafted freehand to a machining-like precision, like Vaucanson’s lathe). Electric motors don’t necessarily, but they need a source of electricity, and that’s either a lot of batteries or another rotating power source, which again doesn’t solve the problem.
Waterwheels can be made with hand tools - maybe even primitive tools - and can achieve surprisingly modern efficiency and power density. They do require the right topography, but then again they spin indefinitely without needing to be fueled. 50hp is still a sizable wheel, near the top of what existed in pre-modern times, but I’m guessing you can do basic things with an underpowered machine.
I don’t think a mill can make the copper windings in the motor and isolate them. Same with the power cable.
You don’t need an electric motor. You just need enough spin. I’ve seen old mills and lathes that run on steam. An electric motor just happens to be very convenient with our current technology.
RSS feeds
I started self hosting my own RSS feed a few years ago, and I couldn’t live without it. It’s the best way to get timely info.
And then you can be the first one to post it on lemmy.
Buttons, knobs, plastic bezels.
At least according to the industry those are all in the past. The future is screens that go to the very edge of the device and absolutely nothing tactile.
And it is bullshit. It is less reliable, less convenient, less cool – To say nothing of the safety disaster that nailing a tablet computer to the dashboard of every car has been.
One of my problems with phones over the last few years is touchscreens that go all the way to the edge combined with UX elements that require swiping from the very edge. It basically becomes impossible to use if you have a case.
Absolutely hate cars with those stupid big screens on the console. Give me buttons and knobs any day.
Eliminating an entire sense (touch) from being used to control things seems to be foolish.
Edit: sorry. Not less knobs and buttons. More knobs and buttons, less touchscreen bs.

Caring about your employees as if they were humans.
That implies it was ever the norm. At best it’s had moments.
Hi, number! It’s your colleague: Another number!
So how about that SPORTING EVENT last weekend?
Something something ludicrous display.
Wrist watches. Extremely convenient, even when your phone is buried or you don’t want to be distracted.
I wear a cheapish waterproof one while swimming. The pool has a clock but I can’t see it without my specs.
Yep. And it doesn’t need to be charged every night like apple watch or similar.
Am looking for a new one if you have any recommendations.
If you find a G-Shock that doesnt incorporate bluetooth and you happen to think of me, pass the name along will ya?
The one I have goes like this. Start stopwatch… Stop stopwatch… Choose between save/delete/resume…deleting…aaaaaaaaaaaaaaaaand deleted… *returns to watch function.
Don’t get the one I got, lol. I’m probably going back to a non-smartwatch after problems with my tic watch.
Oh yeah for sure it’ll be an old fashioned normal watch. Ditched my smartwatch last year.
I have one that uses the gaps between chain links to form a 7-segment display and it’s dope.
Yep plus if you take your phone out you leave yourself vulnerable to being robbed.
- for the wristwatch, if you wear a 10$ casio people will think you’re poor
Or a terrorist

I love collecting CDs
Printing out tickets as a backup. I do this for concerts and travel because then I don’t have to worry about batteries dying, wifi/roaming not being available, getting logged out and having trouble getting back to the ticket, etc.
I also print out maps when doing wilderness backpacks because even if you download the map you’ll burn through your battery life well before the hike is over but a paper map is just as good. If I really need to confirm my location I can occasionally turn on the app and shut it off. I keep the maps in a gallon ziplock so water isn’t an issue.
Ticketmaster is doing their very best to make paper tickets unusable with refreshing barcodes. Funny thing is that “anti-theft” feature is needed because of their own systemic failures. I do like tickets that are just sent to my email or similar (e.g. as an attachment that I can save to my phone) though, it’s better than wasting paper when I know my phone won’t fail me.
Your caveman brain. People think they’re educated an enlightened and everything they do now is so well thought out. Nope, the caveman is in the driving seat for all of us. Even your most high level meetings and interviews are influenced by how hungry, horny, or hurt you are by a teasing comment yesterday. Everyone is looking to establish dominance at any cost, when you don’t really need to.

You know, I see the rest, but I don’t see this. A lot of people are straight-up doormats.

Apparently trains for some people
…how are trains obsolete to anybody?
Hundred of billions of tonnes of freight are moved by rail each year globally, and people travel hundreds of billions of kilometers by rail.
This is what annoys me too. Freight is so crucial and it still moves plenty of people in many countries both in the north and global south. I guess they will think of steam era trains.
Safty razors! Why would anyone spend 20$ on the new fangled 30 million blade razor that mighy last one shave? When you can spend pennies even if you change blades every shave.
I recently switched to a Leaf one and love it. It’s about the same as my Harry’s razor, but a hell of a lot less expensive when even Costco is selling their reloads at $27. The leaf blades are way less expensive, and they aren’t even proprietary.
Oh that is a BEAUTY
I got two of these security razors back in 2017 for less than $50 bucks altogether. Best investment ever. Then, last year I got a Philip razor but I have since just stopped shaving at home. I ask the barber from time to time
That leaf one appears to be $120 lol
But I suppose if you find yourself on the Harry’s marketing train, jumping off for anything that’s actually recyclable is good.
Yeah, expensive up front, but the blades are cheap. I got on the Harry’s train before they got bought up and were cheap. Now, whoever bought them has been jacking up prices, which had me looking for a cheaper alternative.
Harry’s also gave me plastic guilt. There is a lot of waste. :p

Uh oh, what broke on it?

Hmm, good to know. I’ll be sure to not overtorque it. Thank you!
electric razors are just straight up superior though
Electric and safety razors don’t necessarily serve the same purpose. An electric razor can never cut as close to to the skin as a safety razor. I use both
fair, I don’t care about having a close shave so electric does the job for me
Safety* $20* newfangled* might*
It’s like you consciously added misspellings and bad grammar.
I don not know of no 30 million blad razor to.
