The device has two foot boards, both of which are balanced on two wheels. The device’s tilt sensors detect when you shift your weight to turn, traveling at a maximum rate of about 5kph. The foot boards have handle bars attached to help you maintain balance, and can be connected in a variety of positions or separated.
When separated, the device only moves forwards and backwards. To turn, you simply lift and turn your leg as if you were wearing stilts. The overall effect is one of ski-less skis.
Ice is added to a dry Pyrex bowl. When the Ice melts the water reacts with the calcium carbide (place on the bottom) to produce acetylene gas and calcium hydroxide. The acetylene gas then explodes into flames when a match is place on top. It will continue to burn even as the ice melts because it keeps producing acetylene until the calcium carbide runs out.
Dozens of adults from community groups and youngsters from Wrexham schools coloured 82 vinyl tiles to make the paint-by-numbers portrait.
It is on show at Eagles Meadow, and will be used to raise money for the children's hospice charity Hope House.
At 17.5m across, and covering 240 sqm, it is some 50 times the original.
[...]it is the great festival of Lanna duly succeeded from ancient age. "Yi Peng" or full-moon day of second lunar month of Lanna villagers is corresponding to the full-moon day of 12th month of central region during the end of raining season and beginning of cold season when the climate is very nice and fair. One tradition of Lanna other than Loi Kra Thong on the river is to light up the lantern and float up in the sky based on their belief that to pay worship to Phra Ket Kaew Julamanee in the heaven or to relief one' bad luck for more auspicious life.
An enclosed bend sensor attaches to the cheek and measures smile size, a servo motor moves a metal spike into the head inversely proportional to the degree of smile. Through repeated use of this conditioning device you can train your brain to smile all the time. The device runs on Arduino.
In court papers, PepsiCo claims it first received a legal document related to the case from the North Carolina agent on Sept. 15 when a copy of a co-defendant's letter was forwarded to Deputy General Counsel Tom Tamoney in PepsiCo's law department. Tamoney's secretary, Kathy Henry, put the letter aside and didn't tell anyone about it because she was "so busy preparing for a board meeting," PepsiCo said in its Oct. 13 motion to vacate.
Now, to give you idea how Wake works: Alarm clock mechanism I used has 3 contacts, Plus, Ground, and Alarm, which goes high when alarm goes off. This was really fortune for me, as I had only to connect the grounds and use this Alarm pin as analog input (Could not use it as digital as clock runs on 1.5V) and it workes just fine. So, whenever Alarm pin goes high, my code picks this up and switches Mr. Wake from "standby" to "alarm" mode, which makes him switch on IR leds and red LED in Magic Button on, read ambient reading from IR transistors and wait till the reading inceased above ambiant one, which means something is aproaching from above (I have the detection only from above, where clock and Magic Button are.
A building of over 11 floors would be expected to have some extra amenities – and the treehouse Horrace has established is no exception. This particular one comes complete with a mini basketball court – if you thought playing you would never live to see guys playing basketball on top of a tree!
The owner of the edifice is a 56 years old landscape architect by the way, and he say an upwards of $12,000 has gone into building thetreehouse . Asked about where he got the inspiration to build the edifice, he cites a prayer vision he got in the early 90s – going further to say that he built it ‘for God.’ Nobody is arguing with him – and nobody is contesting the assertion that it is the world’s greatesttreehouse either. Meanwhile, building work has not stopped at the 11th floor…the building is still a ‘work in progress!’
Van Abbema created the font by stamping bacteria into paper, and then placing the paper in a jury-rigged incubator, which provided the right humdity and warmth for the organisms. As they multiplied and died, the resulting fonts changed color and shape. As van Abbema says, bacteria "transforms the image to something new," creating something that is literally alive, changing every minute without ever being tended.
Most mammals can sprint faster than humans — having four legs gives them the advantage. But when it comes to long distances, humans can outrun almost any animal. Because we cool by sweating rather than panting, we can stay cool at speeds and distances that would overheat other animals. On a hot day, the two scientists wrote, a human could even outrun a horse in a 26.2-mile marathon.
Why would evolution favor the distance runner? The prevailing theory is that endurance running allowed primitive humans to incorporate meat into their diet. They may have watched the sky for scavenging birds and then run long distances to reach a fresh kill and steal the meat from whatever animal was there first.
Other research suggests that before the development of slingshots or bows, early hunters engaged in persistence hunting, chasing an animal for hours until it overheated, making it easy to kill at close range. A 2006 report in the journal Current Anthropology documents persistence hunting among modern hunter-gatherers, including the Bushmen in Africa.[...]
There is other evidence that evolution favored endurance running. A study in The Journal of Experimental Biology last February showed that the short toes of the human foot allowed for more efficient running, compared with longer-toed animals. Increasing toe length as little as 20 percent doubles the mechanical work of the foot. Even the fact that the big toe is straight, rather than to the side, suggests that our feet evolved for running.
