LEDs in an Engagement Ring

Ben’s engagement ring is awesome not only because it lights up, but because it lights up when he and his girlfriend hold hands: Putting a battery of capacitor inside a ring is nigh impossible, so [Ben] decided to power the LEDs with an inductive charging circuit. A coil of wire wound around kapton tape serves as the inductor and a small SMD capacitor powers three very bright and very tiny LEDs. The inductive charging unit itself is a masterpiece of hackery; [Ben] wanted the ring to light up whenever he and his ladyfriend were holding hands. To do this, [Ben]‘s inductive charger is also a wearable device: a large coil of wire is the charger’s transformer and was would to fit around [Ben]‘s wrist. The entire charging circuit can be easily hidden under a jacket sleeve, making for a nearly magical light-up ring. You can watch a video of the ring at the link. Link

The Amazing Dr. Baker

The following is an article from the book Uncle John’s Supremely Satisfying Bathroom Reader . Illustrations by Kate Beaton of Hark! A Vagrant . Of all of the incredible women we’ve ever read about, Dr. Sara Josephine Baker is one of the most incredible. Her accomplishments are astounding, especially when you consider the time in which she lived. Next time you think one person can’t make a difference, remember Dr. Baker. RICHES TO RAGS Sara Josephine Baker was born to a life of privilege in Poughkeepsie, New York, in 1873. In those days there were no water treatment plants or indoor plumbing -people pulled their drinking water right out of the Hudson River. Unfortunately, the Baker family lived downstream from a hospital that discharged its waste right into the same river. The hospital treated people suffering from typhoid fever -and the germs went straight into the water. Baker’s father and younger brother both contracted the disease and died when she was 16 years old. Although the family was left with no income and small savings, Baker announced that she wanted to go to college to become a doctor, so that she could combat diseases like typhoid. But not many women became doctors in those days. Nevertheless, the young woman insisted, and her mother finally agreed. In 1900, after graduating from the Women’s Medical College of the New York Infirmary and completing her internship, Baker hung out her shingle in New York City. THe next year, she took the civil service exam and scored very high -high enough to qualify for the job of medical inspector for the Department of Health. A MISSION Perhaps because she was a woman, she was given the worst assignment of all: reducing the death rate in Hell’s Kitchen -one of the worst slums in New York. But among rat-infested buildings crammed with poverty-stricken immigrants, Dr. Baker found her calling. She went from tenement to tenement, searching for people with infectious diseases. She said, “I climbed stair after stair, knocked on door after door, met drunk after drunk, filthy mother after filthy mother, and dying baby after dying baby.” Every week, more than 4,500 people in this district died from cholera, dysentery, smallpox, typhoid, and other illnesses, fully a third of them newborn babies. Dr. Baker rolled up her sleeves and went to work. CHILDREN’S CRUSADE Focusing on the infant mortality rate, Baker led a team of nurses who went door to door teaching mothers the value of nutrition, cleanliness, and ventilation. She set up milk stations where free pasteurized milk was given away; she standardized inspections of schoolchildren for contagious diseases; she insisted each school needed its own doctor and nurse; she set up a system for licensing midwives; she invented a simple baby formula that mothers could mix up at home; and she devised a widespread club for young girls to teach them how to properly babysit their younger siblings. In short, she set up a comprehensive health care program for the prevention of disease in children. Her goal: Prevent disease rather than treating it after it occurred. Baker found that babies wrapped in cumbersome clothing were dying of the oppressive heat or from accidental suffocation. So she designed baby clothing that was light, roomy, comfortable, and opened down the front. This clothing became so popular so quickly that McCall’s Pattern Company bought the design, playing Baker a penny royalty for each one sold. The Metropolitan Life Insurance Company ordered 20,000 copies of the pattern and distributed them to policy holders. She found that babies routinely received silver nitrate eyedrops to prevent blindness from gonorrhea. But bottles of the solution often became contaminated, or they evaporated so that the concentration of silver nitrate was at a dangerous level, thus causing the blindness that it was intended to prevent.  Baker invented a foolproof sanitary solution: beeswax capsules, each containing enough solution for one eye. The capsules could not become contaminated and the drops inside could not evaporate. The method was soon being used around the world, and the rate of blindness in babies plummeted. CHEATING DEATH After finding that orphanages had a high rate of infant deaths, Baker became on of the first people to theorize that babies who received no cuddling and cooing simply died of loneliness. After a plan was followed to place orphaned infants with foster mothers, the death rate dropped. Because of Baker’s efforts, the city created the Division of Child Hygiene in 1908 and appointed her the chief. Within 15 years, New York City had the lowest infant mortality rate of any city in the United States or Europe. An astounding statistic: It’s estimated that from 1908, when she went to work for the new division, to 1923, when she left, she saved some 82,000 lives. EXPERT ADVICE Dr. Baker was without a doubt the leading expert of the time on children’s health. In 1916 the dean of the New York University Medical School asked her to lecture the students on the subject. She agreed, on one condition -that he allow her to enroll and attend classes. He refused; women weren’t allowed at his college. So she told him to find someone else. But there wasn’t anyone who knew as much as Baker did. He finally gave in, and because he allowed her to attend the college, he had to open the campus to other women as well. In 1917 she became the first woman to receive a doctorate in public health from the school. World War I strained the U.S. economy, and the poor got poorer. Baker pointed out to a reporter for The New York Times that American soldiers were dying at the rate of 4%, while babies in the United States were dying at a rate of 12%, making it safer to be in the trenches of France than to be born in the USA. Because of the publicity this generated, she was able to start a citywide school lunch program for older children, which became a model for the world. WORLD-CLASS Suddenly, Dr. Baker was in high demand. An international charity asked her to take care of war refugees in France. London offered her the job of health director for their public school system. But she turned the offers down and was appointed Assistant Surgeon General of the United States, the first woman ever to receive a federal government position. What else did this amazing woman accomplish? Following her retirement in 1923: * She represented the United States on the Health Committee of the League of Nations, as the first woman to be a professional representative to the League. * She helped apprehend Typhoid Mary -twice. * She oversaw creation of the Federal Children’s Bureau and Public Health Services, which evolved into the Department of Health and Human Services. * She helped establish child hygiene departments in every state in the union. * She served as a member of over 25 medical societies. * She was a consultant to the New York State Department of Health. * She served as president of the American Medical Women’s Association. * She wrote over 250 articles and five books, including her autobiography in 1939. Dr. Baker’s enduring legacy: by the time she died in 1945, over half of the babies born each year in New York City were cared for at the health stations she established.   See more of Kate Beaton’s artwork at Hark!

The Fangweng Restaurant

The Fangweng Restaurant in Hubei Province, China, is located conveniently near the popular Sanyou Cave tourist destination. But what may strike you as more impressive is that the eatery appears to hang on the side of a cliff! If you didn’t know this ahead of time, you might be surprised, because the entrance gives no clue. You must walk down a passageway that juts out over the Happy Valley of the Xiling Gorge to get to the dining hall. Once there, most of the tables are safely inside a cave, with just a few on a ledge over the chasm. Read about this restaurant and see more pictures at Spot Cool Stuff.

A Field Guide to Tech Facial Hair

According to Wired, the secret to success in the field of programming is facial hair. Notable exceptions include women, of course, and Mark Zuckerberg. Of course, it may also be because those who are the best at what they do can get away with wearing their hair any way they like in the workplace. IT workers fall into different facial hair categories, some of which are shown here. There are twenty types of beards and/or mustaches illustrated in all, so if your profession is not represented here, you can see the rest at Wired. Link (Image credit: Kelsey Dake )

The Edible Deodorant

Candy is dandy and liquor is quicker, but edible deodorant doesn’t only taste sweet, it also makes you smell like roses! Here’s Deo Perfume Candy, the brainchild of food company Beneo : This form of nutricosmetics (nutritional supplements which can support the function and the structure of the skin) is down to the ingredient geraniol, an acrylic monoterpene-alcohol, which is a colourless liquid that can be found in plants such as rose, lavender and vanilla. Geraniol is a natural antioxidant and its fragrance, once consumed as a candy, leaves the body through its pores, creating a naturally sweet smell that can last for hours. Oddity Central has the story: Link (Photo: New Hope 360 )

The Japanese Invasion of Alaska

The Japanese military invaded American soil in 1942 when a force of 500 men overtook the Aleutian Islands of Attu and Kiska in Alaska. They captured a Navy weather crew stationed there and occupied the islands, which are the westernmost parts of the USA. It is now known as The Forgotten Battle but the invasion caused widespread outrage in 1942.  Pearl Harbor was still a fresh memory, having been attacked on December 7 of the previous year. Now, a Japanese military force had stepped foot on American soil – and the 500 had grown to over 5,000 men.  Although Kiska and neighboring Attu (which had been overrun two days previously) were part of the distant Aleutian Islands they were, nevertheless, American. Plans were immediately drawn up to retake the island, known as the Aleutian Campaign. The campaign would not succeed for over a year and would claim many American lives. Today, Kiska is a National Historic Landmark, and abandoned vehicles, weapons, and ordnance still litter the island. Signs warn of unexploded bombs and other hazards. Read about the Aleutian Campaign and see pictures of Kiska from both World War II and today at Kuriositas. Link -via the Presurfer (Image credit: Flickr user Buzz Hoffman )
