Tool Review: Couch Spray Paint. No, Seriously.

Now picking up that ugly thing off the curb just got that much more attractive.

via Byline

A few months back I stored some stuff for a between-jobs college buddy, and took two identical extremely comfy (but extremely ugly) armchairs as plunder when he eventually came and picked it up. He had no more room in the U-haul, and I found the chairs comfortable enough to ignore their ugliness. Most importantly, however, the cat freaking loved them. So they stayed.

Anyway, I was enjoying their comfy-ness, and lamenting their ugliness, with a friend about a month ago. And after a couple of beers, apiece, she suggested spray-painting them. I was tipsy enough to consider that this might actually be a good idea, and if not that, then at least a sufficiently hare-brained idea to draw some decent traffic.

A bit of drunken Googling later, we discovered that spray paint specifically designed for upholstery actually exists. The brand name is Simply Spray, and I bought mine through Amazon. That the color should be orange seemed inherently obvious, at the time.

I was quite sober when the paint showed up at my front door, a week or so later. I get two or three packages a day. usually, so I almost never know what I???m going to find when I???m cutting one open. When I saw the orange light glinting off the sides of the cans reading ???fabric paint,??? my first thought was:

???Oh. Yeah.???

But I was committed, at that point, and to make an already-overlong story short, this stuff actually works pretty well. And considering what a ridiculous idea upholstery spray paint is, in the first place, it works almost astoundingly well.

The starting color of your furniture makes a difference. Over the dead-grass yellow of my plundered armchairs, orange went on extremely well. I was, in fact, so pleased by the resulting orange chair that I decided to try out the contrasting ???periwinkle blue.??? Over the exact same fabric in the exact same color, however, the blue didn???t cover nearly so well. In the bright sun, hints of the underlying fabric are still visible here and there, although under interior lighting conditions this is much less of a problem.

When dry, the color is waterproof, odorless, and does not rub off or transfer under any conditions that I have discovered. Both chairs were a bit ???crunchy??? right after application, but the crunch soon wears off without otherwise affecting the color. And the cat seems to love the painted chairs just as much as their drab predecessors.

I???ve only lived with the spray-painted chairs for a couple of weeks, now, so the long term wear-hardiness of the color remains to be proven. Also, a can of this stuff has to be used all at once. If you absolutely have to stop spraying in the middle of a can, reportedly, you can invert the can and blow it out and store it overnight with the nozzle submerged in water. But generally speaking, once you start spraying, you have to finish the can; even using the underwater trick, any paint left in an opened can will be useless in a couple of days.

The stuff is kinda pricey at $12 for an 8-oz can, as of this writing. My orange chair took three cans to get complete coverage, while the more problematic blue color took four cans to get coverage that???s still a bit thin here and there. With shipping, it came out to about $40 to paint the one chair orange, and about $55 to paint the other one blue. Given otherwise-satisfactory furniture, already on hand, the orange paint actually seems like not such a bad deal, to me, when compared to the time, energy, and expense that would be required to track down and procure equivalent upholstery in one???s preferred color in the used market. And compared to buying new furniture, it???s a steal. And while I can???t say that I???d unequivocally recommend this product to everyone with an off-color chair, sofa, or loveseat, it does work a heckuva lot better than I ever imagined it could, and it was actually a lot of fun to use. Under the right circumstances, it could be just what the doctor ordered.


Portable high-res 3d imaging

Flexible metrology leaves a lasting impression

Obtaining images with levels of detail that are simply astounding, the microgeometry capturing elastomeric sensor from GelSight lets you peer closer than ever before (that???s human skin in the image above).

With outcomes that would usually require time, patience and some seriously heavy-duty equipment, GelSight has developed a system that provides micron-level detail in an instant. Add a camera to the mix, and the minuscule contours can be captured and converted into 3d images.

It works by applying a special synthetic rubber in which finely detailed impressions are made. Click through for a video overview.

The technology was originally developed to be used as a tactile sensorial skin for robots, but the MIT researchers behind the project quickly realised that the scope was a whole lot broader???

It is fascinating to see the ways that these innovations are currently being used, and it makes me wonder??? What role could this approach to 3d imaging play in the rapidly changing world of digital manufacturing?

DIY device gives a modern twist to nostalgic graphic artform

Finnish AllTheMods user Tomi has been cutting up some pretty impressive things since he first built his own CNC machine. One of the more interesting recent explorations is this series of halftone images, milled into a4 sized sheets of stained plywood.

Click through to see a great video of Tomi???s DIY CNC 2 in action, where he shows not only the cutting head zipping along but also a fairly comprehensive overview of the rest of the setup.

You can follow Tomi???s progress with his ever-evolving CNC router at AllTheMods, and don???t forget that if you are not quite feeling up to building your own digital manufacturing machines, it is still possible to create CNC routed wonders through your very own Personal Factory.
