NEWS FROM THE FUTURE – Robot Fish Scan For Pollution

One of the easiest ways to detect otherwise unseen underwater pollution in our lakes and oceans is to monitor the animal life. Sometimes subtle changes in fish population can signal a greater problem that demands immediate attention. Not content to let living creatures be our canaries in the coal mine, a British firm named BMT is heading a project to create robotic fish that will monitor water quality at a fraction of the cost of human divers. 

Called SHOAL fish, the aquatic robots are roughly the size of a large tuna, and are designed to move and act much like a living ocean fish. The SHOAL contain a litany of on-board censors that can detect chemical leakage and other man-made environmental hazards. One one of the robots finds something suspicious, it alerts port authorities who can quickly respond and — in theory — remove the source of the pollution.

A Bed that Makes Itself

Spanish furniture company OHEA has created a bed that unsullies itself automatically. Using two rollers at the foot of the bed, the covers are smooth out as the pillows levitate to accommodate the oncoming covers. Once done, they lower back down into position.

The entire process takes about 50 seconds. While it may be a trifle frivolous the design and mechanics behind it are something to behold.

Gauging Performance Between Compressed Air Rocket Mods

Rick Schertle’s Compressed Air Rocket project from MAKE Volume 15 has been hugely popular since its publication in August 2008. (There’s even a kit!)

Magazine reader Robert is planning to build ten different mods of the Compressed Air Rocket (suggested by the Cub Scouts in his troop) and test them at an upcoming Cub Scout picnic, and he’s looking for ideas on how to gauge performance between the different versions.

I took the new launcher to our Cub Scout den meeting and it quickly turned in to an opportunity to get most of the kids an engineering requirement for one of the badges everyone is working on. The kids all sat around throwing out ideas to improve performance and or durability. I was really surprised by some of the things they came up with. So, I agreed to build their 10 favorite mods in time to test them at the Scout picnic on the 23rd. So far the only idea I’ve come up with to gauge performance between rockets is to time the interval between launch and impact. I was wondering if you might have any other ideas?
Thanks in advance,  Robert.
P.S. I refused to make the most popular idea no matter how many times they asked. The idea was to place a very large nail in the nose and you would be amazed at how many “practical” reasons a group of 10 year old’s can come up with! I grew up in the age of “Lawn darts”, they banned those things for a reason!!

If you have any ideas, please share them here!

Cool Superhydrophobic Surface Demos


Both these videos are from German web retailer Innovative Materials, who apparently used to sell something called “superhydrophobic aerogel” in powder or granule form. In these videos, surfaces coated with this powder react in interesting ways to water. They seem to be sold out of the stuff, but a bit of Googling confirms that superhydrophobic aerogels do exist and can be made in many ways. Exactly what type was used in these demonstrations is unclear. [via Boing Boing]

Super Mario Night Kite


Mark “352K” Rober wrote in with his latest project: an assembly of balloons with throwies inside, creating pixels in the sky. And nice call on tethering it so you can get those toxic coin cells back!

Cutting Wooden Gears with Ideal Grain

Understanding how the shape, type, and orientation of wood grain will change with temperature, weather, and age, and designing wooden objects to accommodate and even take advantage of those changes, is a lot of what separates a dabbler in carpentry from a pro.  Case in point, this article and series of videos by Ron Walters, hosted on Matthias Wandel’s legendary woodgears.ca.

Ron, who is a craftsman of wooden machines, has figured out that, to best withstand environmental changes, the grain in a wooden clock wheel should run in a circle around the circumference, and in radial “spokes” in the middle.  Real trees don’t grow that way, of course, so if you’re really serious about cutting wooden gears that will weather the seasons well, you need to cut them from blanks made up from a bunch of smaller pieces of wood arranged and glued so that the grain pattern, on the whole, is correct.

That, IMHO, is hardcore.  Click through below to see how it’s done.
