[quote=“BlueHeron, post:32, topic:679”]I love it!!!
If you store records correctly, they will probably last for about a century. You just gotta make sure you have enough needles. 
I don’t know if it’s necessary to make new records if you’re living with the people making the music, though. I guess to trade with other tribes? :)[/quote]
here’s a clip of a bike powered record player.
they test it out at around 2:20.
Car tires --> potato towers
Some threads discussing this:

Grow lots of potatoes in limited space, even in the city.
Tires can also be used to make sandals (and have been for years in third world countries). I wore a pair of tire sandals I got in Bolivia for about ten years.
Styrofoam - mixed with organic material, makes lightweight soil for using on top of building roofs. It takes the place of the sand in the soil. Most soil is too heavy for most building roofs, this solves that problem. It has been done successfully somewhere, forget where, think it was New York, to create rooftop gardens on apartment buildings.
Making potato towers out of tires and filling them with styrofoam-based soil, you can produce a lot of potatoes on one building roof.
Awesome. Styrofoam, of course, is also good insulation material.
Sacha, since you listed something for styrofoam, it’s your job to choose the next artifact to keep the daisy chain going. This thread hasn’t been used in a while, but that’s the idea of it.
I listed something for tires too!
Okay, next thing: chain-link fencing.
(Edit: already thought of something - a framework for a shelter, covered with bark, reeds, etc. So someone has to think of something else.)
That’s fine, the only requirement is that you have to keep the chain going by listing something new after you find some use(s) for the last item listed.
Here, I’ll start it up again:
plumbing
Well, plumbing is easy, it can be used for similar purposes to what it is now, ie., to channel water from one spot to another. For example, something is planted ten or twenty feet from a creek or pond and needs water, a length of PVC pipe could bring it a steady trickle.
Here is something harder: chunks of asphalt. There are going to be a lot of piles of asphalt as we rip it up.
you could use chunks of asphalt to plaster together (with adobe or something) to make shelters and you could use slabs of it to make tombs for the dead in a similar way. i can’t think of anything else other than the obvious other stuff you might use rock for.
ok, i don’t know if this counts, but what would we do with the (non native) animals locked up in zoos?
[a brief side trip from the game, I have a bone to pick with asphalt]
ha, tombs to put civilization to bed in. i can’t think of a better material for that!
know how they call chunks of concrete from depaving projects “urbanite”? what would you call it for ass-fault?
I’ve actually heard you can compost it–anybody know anything more about that?
Totally counts. Philosophical concepts, medical practices, etc. count, too.
I’m too tired to come up with ideas for this one right now, so I’ll let somebody else take a stab at zoo animals. Maybe literally if you need meat? Har har.
Yea, aside from keeping potentially invasive species from unbalancing the local ecosystem, I think I might go after them because I’d be the only one with that kind of pelt. Unless it was one of the elephants, in which case I think my entire tribe would be wearing elephant skin clothing for awhile 
yeah, i wouldn’t mind getting my hands on some ivory, that’s for sure.
Tiger skiiiinnnn… :o 8)
Incedentally, that link to the bicicle record player showed them using a paper cone. Ai read on a different video’s comments that this wears out the record fairly fast. Would that be a problem for the hypothetical clay-based sound-recording devices?
New challenge: electricly powered air filters
I’m imagining that the filter has a grated vent, like the kind you find on an AC unit.
The grate could be used to sort out objects according to size, such as removing dirt, sand, or pebbles from larger objects.
It would also have very useful construction applications because of its unique shape. For example, placing it as a vent in a fireplace or smokehouse, or fish-house to keep the air from getting too stuffy.
How about… ice cube trays?
i would thing you could prolly rig 'em up to use as musical instruments, maybe something along the lines of a guiro…?
Also, if you can find a decent fitting lid, you could prolly use them as containers for small seeds.
but prolly the craziest idea is to use 'em to make… Ice Cubes! ;D
How to Use the Solar Funnel as a Refrigerator/CoolerA university student (Jamie Winterton) and I were the first to demonstrate that the BYU Solar Funnel Cooker can be used - at night - as a refrigerator. Here is how this is done.
The Solar Funnel Cooker is set-up just as you would during sun-light hours, with two exceptions:
The funnel is directed at the dark night sky. It should not “see” any buildings or even trees. (The thermal radiation from walls, trees, or even clouds will diminish the cooling effect.).
It helps to place 2 (two) bags around the jar instead of just one, with air spaces between the bags and between the inner bag and the jar. HDPE and ordinary polyethylene bags work well, since polyethylene is nearly transparent to infrared radiation, allowing it to escape into the “heat sink” of the dark sky.
During the day, the sun’s rays are reflected onto the cooking vessel which becomes hot quickly. At night, heat from the vessel is radiated outward, towards empty space, which is very cold indeed (a “heat sink”).
As a result, the cooking vessel now becomes a small refrigerator. We routinely achieve cooling of about 20º F (10º C) below ambient air temperature using this remarkably simple scheme.
In September 1999, we placed two funnels out in the evening, with double-bagged jars inside. One jar was on a block of wood and the other was suspended in the funnel using fishing line. The temperature that evening (in Provo, Utah) was 78º F. Using a Radio Shack indoor/outdoor thermometer, a BYU student (Colter Paulson) measured the temperature inside the funnel and outside in the open air. He found that the temperature of the air inside the funnel dropped quickly by about 15 degrees, as its heat was radiated upwards in the clear sky. That night, the minimum outdoor air temperature measured was 47.5 degrees - but the water in both jars had ICE. I invite others to try this, and please let me know if you get ice at 55 or even 60 degrees outside air temperature (minimum at night). A black PVC container may work even better than a black-painted jar, since PVC is a good infrared radiator - these matters are still being studied.
From here.
Ok, next up. hmmm, how about … keys?
If filed down they might be usable as spikes, or, threaded on a string and used as Jewellery.
Next object: a playstation.
Its effectively a computer. So the cables can be used as rope. The metals can be extracted. The plastics can be used for anything requiring light weight materials (although not load bearing in this case) especially if they have to be water proof.
And zoo animals: two words: monkey butlers.
How about the interstate?

Havent you noticed that plants grow bigger just next to roads? Its because the rainwater runs off of the street, creating a higher concentration of water in a localized area. Streets are the new floodplains (for growing stuff, see).
New challenge: paper making technology (low tech methods)
Mmmm. I’m imagining the wild rice to be had in post-civ Minnesota/Wisconsin…
You could use a bucket and an old window screen to make paper.
New challenge: broken red umbrella with a small hole in it
