I had the opposite problem - our fairly elderly TV wasn't particularly smart, so that was solved with a Firestick that talks to the wifi, but the equally old HDR wasn't wifi-enabled, just an RJ45 port, and trailing a cable to the router was a no-no. Solved with a cheap wifi dongle.

A smart TV becomes obsolete when it’s not able to run the latest apps or isn’t fast enough, similar to a laptop with the manufacturers hoping you’ll buy a new one. Buy a much cheaper dumb TV and use your phone or android box to do the processing instead.

I bought a smart TV five years ago and was rather distressed to discover it had no SCART socket - although I'd converted my DVDs to MP4 format on a USB drive, there were one or two that were reluctant to convert so I still wanted to use my old DVD player which only had a SCART lead.

OK, HDMI cable from laptop to TV, that works ok... later using Bluetooth I could probably use the "cast" feature in Windows 10... but the new laptop I bought to replace my broken one last year doesn't have a DVD player... sigh!

When I finish decorating (circa AD2037 at the current rate of progress) I'll link up various USB HDs and a USB DVD burner in some way so I can play anything anywhere but it's bloody irritating how "old technology" is so swiftly elbowed while one is watching the lesser house fly endlessly circling one's sitting room...

Funnily enough, I believe the Library of Congress keeps at least a copy of its more important recordings on something like wax or vinyl - the idea being that if they use the latest technology like say a CD, then you'll need a CD player to retrieve the information and good luck finding one more than ten years after they made the recording

At least with something like wax or vinyl, you can mount it on something that rotates and run a needle in the groove - maybe even optically scan it with a [email protected] if we're not all back to using stone tools again

Wasn’t it NASA who had saved important info on 5.25” floppy disks then ditched all of the 5.25” drives? I seem to recall that they put out an appeal for anyone who still had one to contact them?

WASHINGTON (Reuters) - The original recordings of the first humans landing on the moon 40 years ago were erased and re-used, but newly restored copies of the original broadcast look even better, NASA officials said on Thursday.

NASA admitted in 2006 that no one could find the original video recordings of the July 20, 1969, landing.

Since then, Richard Nafzger, an engineer at NASA’s Goddard Space Flight Center in Maryland, who oversaw television processing at the ground-tracking sites during the Apollo 11 mission, has been looking for them.

The good news is he found where they went. The bad news is they were part of a batch of 200,000 tapes that were degaussed -- magnetically erased -- and re-used to save money.

“The goal was live TV,” Nafzger told a news conference.

“We should have had a historian running around saying ‘I don’t care if you are ever going to use them -- we are going to keep them’,” he said.

I heard that when NASA saw the shots of Apollo 13 lifting off in the movie, they asked Ron Howard "where did you get that terrific footage from?"

Surprisingly 9 track computer tape drives are still available.
Good luck with old tapes unless you looked after them properly.

When we shipped 'Space Qualified) silicon integrated ciruits to NASA contractors, we had to keep the test data for 25 years as well as provide it to the customer. So data was on 15 inch disks and later, on the next size down - I can't remember if that was 13 or 12 inch. 20 years later, we had nothing which could read the discs and neither did the customer. I believe that at vast expense, they found a company that still could. Some one once said that if paper and pencil had just been invented, it would be hailed as the miracle new data storage medium.

Anent home computers when I upgraded I made sure that the new machine could read the previous discs as well as whatever was fashionable at the time. The idea was that I should copy old data on to the new format so that I could access it on the next machine and so on.
What I found I couldn't do was use the software that created the data as upgrades of operating system often failed to provide for outdated systems. That was particularly upsetting when I could no longer run software I had written myself in a high level computer language which modern operating systems do not support.
I am reduced to keeping several out-dated computers simply so that I can use that software and then I have trouble getting a modern printer to work.

Could you not print to.PDF and then use a USB stick to move it to a modern machine?
PS. Which high level language?

The language I used on home computers was BASIC for which I had not only the Interpreter but a compiler. Altering the systems to print to a file which could then be transferred to a modern machine/printer was of course an option, but too ponderous.
The systems I needed most were my motor race handicapping database and calculating programs and normally we got timekeepers' practice times by a 3½" disc, assessed those times and the historic data and printed out the handicaps and race starting grid. That had to be published 60 minutes before the due start time which could be a bit tight as it was. Also a bit tight was our "office space" so adding another computer could be physically difficult - Silverstone and Donington would not have been a problem but at Mallory, Lydden and Snetterton we had to use a corner of the timekeepers' room . . .

Yes same for me - I had a GBASIC compiler and produced a set of Radar training programmes (FFT, Pulse compression, doppler shift etc). Doesn't work with anything later than Windows 2K so I used excel with the analysis package to rehost them.

Voyager (launch 1977) is still transmitting, should last until 2025.
Maybe hose white goods makers should be made to give a decent guarantee.

It looks a bit like this...

Just thinking aloud - I haven't tried this - but if the bearing has no rubber or plastic parts, then what about submerging it in grease which has been heated to a liquid state? The grease might then flow into all the spaces in the bearing and remain there when the grease cools back to a paste. As long as the melting point of the grease is above the operating temperature of the engine, that might work, I don't know? Maybe the grease would be compromised by melting it?

Best done outside:, the fumes might be nasty, (and flammable).

You should watch Norsemen on Netflix, partly because it's a VERY funny and well written series that pokes fun at our world through the lives of Norsemen of a thousand years ago

In one scene they have to contact the home village so they write a note and tie it to the leg of a raven then let the bird go. One Norseman then turns to the other and says "It's amazing how far we've come technologically. I mean look at our communications system, it's so advanced that I bet there's not a single person alive anymore who knows how it actually works"

Years ago I used a product called “Linklife” or similar, which was a meltable graphite lubricant for motorbike non o ring rear chains. Boil in the tin. However, where a dry bearing can be removed, I’d probably just replace it with new.

Using a vice, a piece of wood and the largest socket piece I had as a drift which was still slightly undersize I popped off the 44mm diameter bearing from the pulley. However, pushing the new bearing in all the way into its concave recess without damaging it using the same socket piece was going to be a problem until I had a brainwave and used the old bearing itself as the drift.

I then ran a bead of automatic transmission fluid around the bearing races but it just seemed to sit there so I let it sit in the sun for a few minutes and through the gap the oil disappeared, oiled the other side the same way and put the idler pulley back on the engine - 30 minute job - not counting waiting 15 minutes in the empty reception room of an allegedly reputable global bearing company before I walked out, so got a Chinese one from the auto shop down the road. Judging by the shear number of upmarket cars that were parked outside that global bearing company I think I am in the wrong business.

Is it just me who thinks that ATF is not really a suitable lubricant for a ball race?
