Art du Jour 39

Breathing Space

If there is such a thing as a serious artist, I’m not it.  If it feels like work, I don’t want to do it.

This was 1% work and 99% fun.  I am in love with the colours.

Maybe I’m going through a phase or maybe I’m still feverish and delirious from a couple of days spent this side of miserable with a stuffed up head.  Or maybe it was the other side of miserable.  It was the bad side, anyway.  I consoled myself by watching multitudinous episodes of Netflix crime shows, congratulating myself on not being a murder victim.  See, there’s always somebody worse off.

It’s a beautiful sunny March weekend!  Hope you’re having a good one.

New Part Day: Really, Really Wide Screens

Hackaday

Once again my inbox runneth over with press releases, Kickstarter announcements, unsolicited emails, and a bunch of product announcements. Most of these, of course, are never to be seen again. Once in a great while – statistically insignificant, really – there’s a product announcement that’s just interesting enough to take a closer look at. This time, it’s a really, really wide screen.

LCDs are curious beasts when it comes to display interfaces. Back in the bad old days of gigantic tube TVs, the aspect ratio of these displays was fairly limited. You could get a 4:3 display, and with the rare exception of o-scopes, vector displays, and other weird devices, that was it. Since then we’ve moved to LCDs, a promising technology if you want a display in the shape of a car dashboard, or as a thin strip to put on some rackmount modules. It took this long…

Prince of Orange, or Why Orange is Good for You

Standing Ovation, Seated

Nikolai Tarkhov, a Russian painter who settled in France six years before the Revolution of 1917, and died there, impoverished and forgotten, thirteen years later, was in love with orange. Take Van Gogh, max out reds and blues in his palette, add a good measure of orange colour, and you’d get very close to Tarkhov, though not quite.

I guess I know why he loved orange. Perhaps, this is why we all love this colour. It is a very rare or temporary colour in nature. The sun becomes orange for the last few minutes of its daily existence above the horizon. A pumpkin turns orange when it is ripe and then it gets eaten. A tree gets orange before it metaphorically dies for the season.

Orange gives us an acute feeling of being alive right here and then. Orange is a pinch that wakes us up from whatever gloomy state of mind…

Cannon Sucks Balls at 600 mph

Hackaday

Every day we humans hang out and think nothing of the air that is all around us. It is easy to forget that the air has mass and is pulled down to the earth by gravity creating an ambient pressure of about 14.7 psi. This ambient pressure is the force that crushes a plastic bottle when you lower the internal pressure by sucking out the air. [Prof Stokes] from Brigham Young University has used this powerful ambient air pressure as the power source of his ping pong ball cannon.

Instead of filling a reservoir tank with compressed air and using that to fire a projectile, this canon has the air removed from the barrel to create the pressure differential that propels the ping pong ball. The ball is put in one end of a 10 ft long tube. That end of the tube is then covered by a sheet…
