Designed for Landfill

The Sony Walkman turned 30 years old this year, at almost the same time as I did.


Back in the old days a cassette walkman had big chunky buttons, with “Fwd” on one side, “Rev” on the other side, “Stop” in the middle and a bigger “Play” button somewhere equally obvious. They didn’t have a “hold” switch because those massive buttons were never going to be pressed down by accident unless you dropped it on all four of them at once. Doing that would jam them for a minute until you thumped each button one at a time which would generally un-jam them again, sometimes leaving them a little looser but almost always still working.

One happy day “Auto-reverse” came along and removed the need to take the cassette out to play the other side, and at about the same time they got a bit smaller and only needed one AA battery instead of two. As rechargeable batteries slowly came down in price I’m sure I was quite contentedly musically mobile for a while there.

Unfortunately this got me hooked early, and for about twenty years now I’ve combined the activities of walking and listening to music, taking my mind off the massive heavy rucksack I’m often carrying usually via something trashy with the bass boost on. CDs are too flimsy a format to ever really be portable, but they got me used to skipping tracks and I eventually switched to the instantly-obsolete minidisk format. I’m now thinking about getting an MP3 player, but I can’t find anything that isn’t almost completely unusable because of basic design flaws.

This is all I ask…

1) I’d like one that takes a standard sized interchangeable battery, preferably a single AAA, with as long a life as possible. Nothing affects my enjoyment of a music player quite so much as it being silent because the battery has run out, and being able to carry a spare charged battery is the only practical way of making the thing truly portable.

2) I want something reasonably easy to navigate by feel so I can keep it in my pocket out of sight. Not just because I don’t want to get mugged for it, but because I need to pay attention to small matters like crossing roads, looking where I’m going, and generally not ending up like those earphones in a pool of blood from the road safety ads.

3) It’d be handy if it could be reasonably rain proof, or at least come with a rainproof cover it can stay in while I use it. I need this because I live in the UK where it rains quite a lot, and I plan to go out in that rain quite a lot with a portable music player. That’s the whole idea of it being portable. If I wanted to stay at home where it’s dry then I’d use my computer instead. I had a waterproof Sony Sport Walkman in about 1988 so I don’t feel I’m asking for the moon here, but water resistant electronics don’t even seem to exist any more. What happened there? It hasn’t stopped raining.

4) I’ll have it in any colour that won’t show dirt too much. I’ll try not to actually drop the thing in any puddles, but I’m not going to wash my hands before each time I touch the stupid thing. Black works, any other darkish colour would do, white would be bottom of my list.

I’m struggling to find anything that meets even the first two criteria, and I’ve now started just looking for something with as many visible buttons on it as possible.

How does one operate an MP3 player which only has one button anyway? Presumably the sodding thing changes function all the time and you have to keep taking it out of your pocket to find out what the damn button actually plans to do next time you press it. Or each side of the same button does something different so that you have to get it the right way up in your pocket, guess which corner of the circular button you’re stabbing at and then wait a few tantalising seconds to find out whether you’ve skipped to the next track, turned the volume up, turned the volume down or skipped back to the start of the track you were in the middle of. You can be tantalised for even longer if the middle of the same big circular button also happens to be “Pause”.

Touch screens? Horrible! Fine, I guess, if you’re sitting somewhere warm and dry (because I guess you can’t wear gloves), devoting all your attention to dragging the pretty little animated icons around. Not so much fun if you want to go anywhere where you might have to look away from it for a minute or where anything might bump it unintentionally. So you can’t actually put it in your pocket and walk, drive, do the washing up, exercise, weed an allotment or eat anything to music.

And why the hell are these things all white now? WHITE?? They’re supposed to be portable, and yet if you’d like them to stay shiny at least until the novelty of having something new has worn off you can’t put them in a pocket, can’t touch them if you’ve been reading a newspaper, can’t put them down on any surface that might have any dust on it or in a room that might ever have had any children in it. And it must take the potential resale value down to a small fraction at a stroke, because after just a few weeks use it’s going to be a highly unfashionable shade of yellowy grey.

And is it really too much to ask for corners that won’t rub off? Coloured plastic has been around for quite some time now and is available in a vast range of colours, several hundred of which would make very nice colours for the casing of a small electrical device. It’s really not necessary to coat it with a metallic finish of any description, and it’s going to look much better in a few months time if it doesn’t have a coating that wears off all the corners.

But the battery situation is just unforgiveable. Having agreed - more or less - on things like standard time, which side of the road to drive on, and roughly how many volts are going to come out of a socket in a wall, humankind went on to produce battery cells for mass consumption in some common standard sizes. Both AA and AAA rechargeable batteries are easy to source, durable, easy to charge and easy to replace – they’re the quite blindingly obvious choice of fuel for a small portable electrical device. So why would anyone decide to put a completely non-standard sized rechargeable battery in a portable device and then seal it inside so it can’t be charged outside the unit?

Because, obviously, anyone who wants portable music enough to buy one of these things is going to want to sit next to their computer all the time to recharge it. They take 3 or 4 hours to charge, so when the music suddenly stops half way to the 24 hour garage one evening, all you have to do is turn around, walk back home and sit next to a USB port for three hours and then you’re up and running again.

OK it means they can be ultra slim, but I can fit seven AAA batteries in the tiny fifth pocket of my jeans - it’d be well worth an extra 3mm width to be able to carry a spare battery around with me. For when the battery runs out. Which it is generally going to do while I am in the middle of walking and listening to something, rather than when I am conveniently sitting at home next to my computer.

Especially since some MP3 players have a battery life of an unbelievably low six hours - perhaps that’s so that you can’t actually get too far away from your PC before the battery runs out? I despair.

The Fabulous Wrecked Tent Project

On the last night of Glastonbury I fell asleep in Merrick's tent, with a trickle of rainwater falling on me right in the middle and a small pond growing at my feet. I was warm and tired enough to fall asleep/pass out quite quickly, but instead of counting sheep I drifted off dreaming about groundsheet patches and reinforced seams.

It's a lovely tent - a modern dome design which is easy to put up, flexes in the wind and is strong and sturdy, but made almost entirely of cotton rather than nylon so it breathes and shades like cotton bed sheets. It was bought for Glastonbury 1995 and has been well used since then, but it needs some serious repair work to keep it in service much longer.

As I recently ranted, I hate the way so many people throw things away and buy new replacements rather than repairing and maintaining what they already have, and this tent is such a nice object in itself that I just couldn't resist making a project of it. I thought I'd post my progress here in case it helps anyone else not have to buy a new tent, and in case anyone has any tips as I go along.

I took the tent home with me, but instead of drying it out the whole thing was so grubby that I threw it straight in the bath to wash it first. I started off by handwashing the fly sheet, which is about the thickness of good quality bedsheets and tough enough to scrub with a scrubbing brush. The water coming out of it was only a very pale shade of brown after about the sixth rinse, so I wrapped it in a sheet to keep the fittings safe and put it in the washing machine to spin it halfway dry before I hung it up.

The previously clean white sheet came out so dirty that I changed my mind and put it back in for a proper 40 degree wash with soap.

With the fly sheet drying outside on the line I started cautiously prodding the inner to see if I could get away with not washing that. The inner is awkward because it's stitched onto the groundsheet, but 14 years of mud, sweat, mildew, squashed insects and ...whatever that is... really did need to come out of it before I could do anything else.

Although it will look great (and breathe better) after a wash, cleaning it isn't just for aesthetic reasons. Tiny particles of grit stuck between fibres will eventually wear and break them - some of the smaller holes in the inner look as though they might have been caused this way - and patches of dirt will affect the tension and flexibility of the fabric, making it impossible to sew it straight or with a consistent tension. Wonky or badly tensioned sewing pulls in some places more than others which causes further rips, and the inner fabric is so fine that a little will make a lot of difference.

So into the bathtub it all went, the groundsheet bundled up out of the way making it look like I had a dead body in there, and out came blackish water and 14 years worth of Glastonbury mud. The fabric was too thin to withstand the scrubbing brush so there ensued much energetic squishing, and the rips meant I didn't dare lift any of it out of the water as the weight of it wet was likely to tear it even more.


After 11 or 12 changes of water I concluded that the really black bits were a permanent feature, they'd probably look better when it dried and they add character anyway, so I left it to drip in the bath for a while and then spread the groundsheet out in my bedroom, with a chair inside it to lift the inner up to dry as best I could.

I just love how doing things like this doesn't seem to strike cats as particularly unusual - Mizzy walked right past this enormous thing she'd never seen before which was taking up almost the entire room, and paused only for about half a second to determine that it was wet and therefore not interesting.

By morning it was dry enough to get it outside, and when I put the poles in to spread it out properly it dried out in ten minutes flat in the baking hot sun. The next job will involve either waterproofing it or taking revenge on it for soaking me at Glastonbury. I'll keep you posted.

Don't Buy a "Green" Thing

There are so many “green” products out there – from eco ironing spray to solar powered cherubic water features – that it’s easy to miss the simple fact that avoiding a purchase entirely is usually the greenest choice of all. The truly green alternative to a mains-powered water feature, for instance, is not a solar-powered one with a huge manufacturing, transport and disposal footprint, but an entirely non-electric one (like this made from a bathtub rescued from landfill), or just doing without a water feature altogether.

Making something pretty by re-using what would otherwise be wasted is a nice idea, and there are loads of projects and websites on making funky clothes, jewellery and desk tidies from reclaimed waste. But how often are you likely to wear a newspaper dress, how many pen holders could anyone really need, and how much jewellery would you avoid buying new if you mastered the art of making bottle-top earrings instead?

We’re so hooked on consumption that we’re coming up with ideas to reduce it by essentially consuming more. We’re inventing more “needs” that we can satisfy with ideas borrowed from sustainable solutions, while forgetting that we already have real needs far more deserving of our efforts to meet them more sustainably.<

Along with this, almost all products which are actually useful have just about succumbed by now to the natural state of decay known as the Shoe Event Horizon, which caused global societal collapse on the planet Brontitall in “The Hitch Hiker’s Guide to the Galaxy” by Douglas Adams:*

“The foundation of the Shoe Event Horizon theory is that when depressed, people tend to look down, and when they look down, they see their shoes. To cheer themselves up, they might buy themselves a new pair. Thus, in a generally depressed society, demand for shoes will rise.

In the critical condition, demand for shoes rises faster than the capacity to make good quality footwear. As shoe quality decreases, the demand increases further because shoes wear out faster and need to be replaced more often; as the demand for shoes increases, cheap mass production causes shoe quality to drop even more. What results is a spiral of increasing shoe demand and decreasing shoe quality. Eventually, this destabilises the economy to the point where it is "no longer economically viable to build anything other than shoe shops", and planetary society collapses.”


It seems to me that it is no longer economically viable to manufacture anything much other than cheap, shoddy products that don’t properly withstand normal wear and tear, that are deliberately designed not to be repairable by the average user and that are inherently disposable, thereby ensuring the future purchase of replacements as often as manufacturers think they can get away with. The result is that we’ve stopped expecting anything to last, we don’t expect to have to form the habit of maintaining anything, it rarely occurs to most of us to even attempt to fix anything that breaks and we’ve largely lost the skills we need to do so even if we wanted to.

How come so many people who grow their own vegetables don’t know how to sharpen the tools they use? Why, when everyone knows they should only boil the water they need, do they not also know to regularly de-scale their electric kettle to prolong its useful life? How many people use an energy efficient light bulb in a lamp, but throw the lamp away when it stops working because they don’t know to check and change the fuse? How many of those designing exciting “eco” clothing ranges throw away good versatile T-shirts from their own wardrobes when they don’t know how to get rid of a stubborn stain?

Instead of making very beautiful bottle-top earrings and pen holders, perhaps we should concentrate on things we couldn’t just entirely do without – basic clothing, tools, lamps, kettles, bikes, taps, everything that serves a useful purpose and is a solution to a real need rather than an invented one. We then need to teach each other about how these things are made, which designs are most durable, how to fix them when they break and how to maintain them so they break less often.

Why has learning simple repair and maintenance techniques yet to become fashionable the way "eco chic" apparently has, and where are all the reduce-reuse-recycle-but-see-if-you-can-REPAIR-it-first sites?

I’ve made myself a new “repair and maintenance” tag for this kind of thing and I hope you all have nice sharp garden shears now. I'll try to find something else to fix while you're busy descaling your kettle.




* Sorry to stereotype but I imagine I’ll now get Douglas Adams fans commenting that they’ve memorised the entire text of HHG and the planet Brontitall isn’t in it, so thought I’d better just mention that it’s only in the original BBC radio show and that memorising the entire text of HHG isn’t likely to get you a girlfriend.

Sort Your Shears Out!

Everyone’s been clipping everything in sight since we’ve had some sunshine here. On Monday the council used a petrol ride-on mower for all the grassy paths, the neighbours had a gardener doing their lawn with an electric push-mower, all the housing associations sent their hedge-clipping-chainsaw-thing man round and almost everyone else I saw was laboriously hacking at hedges and undergrowth with blunt shears while sweating a lot. So it might be a bit late to tell you this.

It’ll all need doing again in about two weeks though, and the simple non-electrified garden shears that most of us use are about a hundred times easier and more effective to use if you maintain them properly, so here’s how to sort out a pair of shears:

First wipe them clean so you’re dealing with handles and blades rather than a layer of plant goo and grit. Little bits of grit will totally mess up the sharp edges and the pivot, so rinse them even if they don’t seem muddy, just in case.

Close the blades together, hold them up to the light, and look between the blades to see how well aligned they are. If the blades are bent away from each other even a tiny bit then at best they’ll only cut part-way through everything. If they meet at the pivot and the tip but there’s a chink of light in the middle then you’re holding a pair of self-blunting shears. Blades bent in towards each other will scrape their sharp edges together every time you close them, so they’ll be blunt in no time even if you just open and close them without cutting anything.

Bend the blades carefully back into shape until they pass each other very closely and lie flat against each other – you shouldn’t see any light between them sideways-on when they’re shut. I tend to do this by wedging one handle between my foot and the ground, putting a brick under the part of the blade I want to bend, another brick under the loose handle to stop the blades closing together, and then pushing with slow steady pressure on the blade until I can just feel it start to move. Don’t hammer blades or apply pressure too fast in case they snap, and check the chink of light between the blades every time you may have bent them even slightly – a little makes a lot of difference!

Once you’re sure they’re aligned properly, sort the pivot joint out. If they’re stiff you might have grit or gunk in the joint, which a scrub with an old toothbrush in warm soapy water will probably sort out. If it’s rusty then take as much rust off as you can with fine sandpaper and wipe clean with something dry. Then work some oil into the joint so it opens and closes easily. If they’re still stiff then it might be worth undoing the bolt to sand the parts you can’t otherwise reach, putting the bolt itself in Coca-Cola overnight before cleaning its screw thread with a toothbrush and soapy water, then drying and oiling the whole thing before putting it back together.

Finally, you need a sharpening stone. If you’ve ever chewed a piece of grass you’ll know that it’s very fibrous, and so are woody things like hedges. Clipping the stuff will blunt blades quite quickly, so they need sharpening up again every ten minutes or so to keep them cutting easily, otherwise you’ll spend lots of effort just bruising grass.

If they haven’t been sharpened for ages then it’ll take a bit longer first time, but once they’re done they’ll only need a few scrapes to get going again when they start to lose their edge. If they’re very blunt or if there are any nicks in the blades, take them to a locksmith-and-cobblers shop first and ask nicely if they’ll grind them on their machines before you use a sharpening stone for a smoother finish.

Get the sharpening stone wet, look at the blade to see where the tiny slope at the edge is, then drag that sloped bit across the stone – you don’t need to press very hard. If you then look again at the blade the part you’ve scraped will be shiny, so you’ll see easily if you’ve got the angle right and with a bit of trial and error you’ll soon work out how to get a decent sharp edge on a blade – ask a good chef to teach you how to sharpen a knife if you're struggling.

Go off and cut things, enjoy the nice clean slicey noise they’ll now be making, remember to sharpen again a little bit every ten minutes or so, and you’ll gradually stop thinking of shearing as really hard and difficult work.

No petrol, no battery, no mains lead, no fuel costs, no sweat.
