We live in a world full of uniform, mass produced, cheap little wonders. Case in point, the humble pull tab. Tossed out as refuge in the millions every day, but what better way to attach something on the wall? Just screw a pull tab to it and hang it over a screw/nail in the wall.
If you are anything like me, math class was only good for one thing: Quieting down that analytical part of the brain long enough to get in some good doodling, which is why, in order to pass a math class, I had to stop bringing paper and just hope I could absorb something from the lecture before passing out from boredom. Now I find I just had the wrong teacher. If Vi Hart were my teacher, I think I would have learned at lightning speed. Check out the videos above for a sample.
If you like the concept of learning math, but don’t relish the slogging through textbooks, I highly recommend her site. I actually learned some very helpful things in most of the videos I’ve watched so far, and I enjoyed it. http://vihart.com/
Johnathan Post has a very impressive new method for seeing 3D content on video screens without shutter glasses. While there are some obvious reasons why this particular method isn’t going to catch on, I really am vastly impressed with his ingenuity.
I’ve been wondering ever since the Hypercolor days why no one sells a house paint that changes from black to white as it gets warm. The same goes for shingles, jackets, etc. I can only assume that the costs of production must still outweigh their value as an active thermal insulation, but now that I see this, I’m tempted to at least make myself a jacket. In the video below, there is a tutorial on how to make fabric that quickly changes from black to white as it gets hot.
“Knockers” is what Steve Wienecke calls his game. Somehow I don’t think that’s gonna stick, but the game just might. He’s scaled up a pool table enough to play it with bowling balls. I’d love to give this a shot. It looks like more fun than regular bowling. Just don’t try to build one of these in your garage unless you like holes in your walls.
I think all of us need a reminder sometimes that we don’t need expensive materials to make something awesome, as illustrated by this poseable cardboard Gundam.
If you want to avoid shakycam footage, there are a ton of ways to stabilize your camera, ranging from DIY projects, to a huge variety of devices (see here) ranging from simple and affordable, all the way to professional units where if you have to ask the price, you can’t afford them. All these options weren’t enough for this guy though, he’s taken the DIY approach to a new level, giving his rooster a helmet cam. If you’ve ever picked up a chicken, you know that when you move their body, their head stays in the same place (vestibular ocular reflex).
Why buy a fancy steadycam, when you can just carry a chicken? Video below.
It seems to me he has the camera pointed the wrong way. Chickens don’t look straight ahead, they look to the side. The real challenge here is to keep the chicken interested in looking at what you are filming, which could be a good way to make movies for people with short attention spans.
This antenna being developed by SPAWAR Systems uses a jet of seawater as its conductor. It can both recieve and transmit, and by adjusting the length of the jet, they can better tune in a specific wavelength.
Don’t expect to have one of these on your cellphone any time soon, but it seems like it would have a lot of potential for sensors floating out at sea.
The Groasis Waterboxx was the grand award winner in Popular Science’s 2010 top 100 innovations list. The base has a water reservoir which you fill once or very rarely. Any rainfall or morning dew runs down the top of the lid to water the plant, and the condensation from the reservoir collects on the underside of the lid and serves to water the plant in dry times.
At $275 for 10, it seems a bit pricey for it’s intended use in poor, arid nations, especially considering you could likely make a passable version of these out of old tires and trash can lids, but I see no reason it has to be an eyesore. I can see a nicer version of this having use in parking lot plantings in semi-arid cities like Los Angeles, or for newly planted trees along highways.
Happy Halloween everyone!
This is my Jack o’ Lantern for the year, my usual carved watermelon. For anyone who isn’t tied down by tradition, I highly recommend them over pumpkins, it went really smooth and only took about twenty minutes using a birds-beak style paring knife.
This is the first time I’ve tried removing the skin and going for dimension. The skull is all one piece except for a few teeth in the back of the mouth, and the brain is still attached. I’ve hidden an ultrasonic mist maker and LED in the brain cavity so illuminated fog spills out over the brains.
Update, Chicken Zombies in search of brains:
Just when you thought Halloween was safely over, the zombie chickens show up to eat any melon brains that may have been left laying around.
A couple of my past watermelon carvings here.
