OT: e-waste

[N_Cook]

Anyone seen clever alternative uses for CRT computer monitor cases or
other uses for e-waste stuff, converted to completely different
functional and saleable stuff?

I was impressed with this recent UK TV documentary
http://www.channel4.com/programmes/kevins-supersized-salvage/episode-guide
Interesting mixture of engineers , designers and artists. My favourites
were the bird-boxes, amazing what people paid for them.
I'll have to research the meltable plastic waste , via shredding , to 3D
printer feedstock.
Whether viewable off-internet , I've no idea. But if its anything like
my ISP / Google recently. Try to go to google.com and get redirected,
via reading my IP, to google.co.uk, recently has been redirecting to
google.be and google.ie and won't let you go to google.uk

On the 3D printer feedstock front. Are plastic "milk jugs" in the USA
what you carry milk home from a supermarket to home in, rather than in
the UK we would call them milk bottles.

For a long time I was intrigued to convert one of those big, honkin'
IBM 3270 display units to a back-lit fish tank. But, having a Black
Belt in Procrastination, I never got around to it -- even tho' there
was a time in the late 80's when I could get a number of them for free.

A fish tank made from a flat panel thingy would not be a good choice,
I suppose....

Turning a Mac Plus into a fish tank was old when it was new.

You caould take an LCD monitor and turn it into an ant farm.

Gee I wonder if you could do that and keep the monitor working.

My sister's dog does. He doesn't sit there and watch it for hours, but
every so often he'll notice something and bark. I suspect it works better
now that tv sets are generally bigger. I think he was barking at an
elephant last week, but it's generally dogs. The odd thing is, he doesn't
bark that much generally, seems to miss many dogs walking by outside.

Nigel,

Yes, in the US we call them 'milk jugs'. Usually from type 2 (high
density polyethylene) plastic. While milk bottles wold also be correct,
many people would thing that you are talking about the reusable glass
ones, though I've heard those called jugs as well.

A "jug" usually has a handle. A "bottle" rarely does.

But the bigger the bottle, the more likely it needs a handle to carry it.

Certainly 1l bottles of juice will tend to not have a handle, while 2l
might, and a larger size would. Same plastic used in each.

There was one project in Popular Electronics in the sixties where someone
put speakers in a pair of "milk jugs". Not really great, but useful for a
utilitarian speaker, protect the speaker and improve the sound a tad.

Well, I knew there would be an exception, but it just seems the
action would attract a dog.

CRTs usually have a whole bunch of easily accessible magnet wire (high
purity copper, emaneled) taped up in a loop around the frame.

Microwave ovens have MOT transformers and high-voltage caps. CV^2, so
they pack a lot of punch. The MOT high-voltage part is grounded to the
chassis, so it's totally lethal if not handled with great mindfulness.
They can be made into high-current transformers with an angle grinder.
The magnetrons have highly toxic parts, so breaking those up with an
angle grinder will make you die of cancer in a week.

Refrigerators and air conditioners have compressors which put out up
towards 30 bar, compared to the 8 bar of your normal shop air. They are
filled with gaseous refrigerant which needs to be burned at high
temperature (e.g. arc furnance made from a MOT) or brought to an AC
service shop. When burned, hydrogen flouride (HF) is usually formed. This
is lethal too.
These compressors also make good roughing vacuum pumps. Reportedly two in
series will bring the pressure down to 1 torr. This may or may not be
enough for sputtering. It's more than enough for CO2 lasers.

T5 fluorescent tubes can be reporposed too. The white coating scrapes off
but doesn't dissolve. They contain mercury so use disposable latex gloves
and don't touch your face while handling them.

Laptop batteries contain rechargable cells. These can usually be
reconditioned through a variety of ways.


I'm currently educating myself in these arts further. It seems like time
well spent.

Is that what the program is about? Because that IS clever. =)


Some of my ideas are to for example turn old fridge housings into
housings for 3D printers. With a CO2 laser it could be a LAM; laser
additive manufacturing. - High-tech made out of scrap! Standard sizes too.

If you pulverize glass you could quite possibly melt it into new, high-
performance parts with LAM. They are very versatile and able to consume a
wide array of recycled materials.

For this to have a real impact though there needs to be a local demand
for recycled goods like this. Ideally this would be like an RTS game and
to get the stuff you ordered from your local maker-bot you need to bring
it the resurces that it demands. I think kids would like it. - New toys
in exchange for a bit of scavenging. It would teach kids so much!

I think making on-demand designs like this should be a Real Job (tm). A
great first step in this direction is the excllent website locted at
https://www.bountysource.com/

But, and a big but, is that really few people have the time to be
creative like this in most Western societies. There is such social
pressure to flaunt status by how much money you make that the actual
money is devaluated.


Making visually and olifactory attractive housing with localized
recycling would without a shadow of a doubt be valable beyond words,
provided you get the land for cheap. You would need to found new cities
in the wildreness and build municipal infrastucture for them for real
estate prices to allow for this.

Perhaps virtual reality-enabled telepresence would allow for such a
phenomena!

Yes it was more like conversion than salvaging.
All that was left was some subpanelling for cockpit switchgear, all else
had found a new home with the minimum of processing.
A large section of the cabin , fitted with end panels , went for
garden-office , complete with part of Airbus A320 script on the side,
new owners over the moon about their new 7000 GBP addition to their garden.
Impressive looking desk lamps , I think went for 350 GBP each made out
of one of the pierced cast/machined seat supports plus a bend up seat
panel, with lamp socket and cable added.
Kids bedroom combined bench-seat/storage boxes went like hot cakes,
marginally converted overhead lockers.
But my favourites were the incredible variety of birdboxes made from
otherwise impossible brown composite tubes with impossible angles and
diameters and manifolds, for the recycled air ducting that were visible
to the fliers would make them question long distance flying breathing in
other people's exhalations multiple times.

 

[N_Cook]

I just found the associated? commercial site
http://www.aircraftworkshop.co.uk/product/bird-box-12/
I'm not surprised they are all out of stock, even at those prices.
I somhow doubt all that piping from scrapped airbuses will be going to
landfill anymore
