Wiimote hacked to create a multitouch display on almost any surface!

Thanks to Marc Avery for the link.
Awesome idea, great youtube video.
Via gearlog:
Using a Nintendo Wii remote and some software that he ginned up himself, Johnny Chung Lee of Carnegie Mellon University took a few ballpoint pens, replaced them with IR lights, and presto! Since the Wii tracks IR lights, Lee found that practically any surface -- a projector screen, a tabletop, an LCD screen -- could be turned into a multi-touch screen.
You can download Johnny's software at his website.
The video is here.

Modular Domino USB Drives, with changing dots

Only conceptware for now, this strikes a special cord for domino aficionados everywhere.

Apparently, the more full the drive is, the more white dots will appear on the face of the drive.

Two drives connect together to form a whole domino.

Calcium in the news

It's common knowledge that:

Calcium is an important component of a healthy diet. Calcium is essential for the normal growth and maintenance of bones and teeth, and calcium requirements must be met throughout life. Long-term calcium deficiency can lead to osteoporosis, in which the bone deteriorates and there is an increased risk of fractures. While a lifelong deficit can affect bone and tooth formation, over-retention can cause hypercalcemia (elevated levels of calcium in the blood), impaired kidney function and decreased absorption of other minerals.[5] -Wikipedia
Scientists at Texas A&M AgriLife's Vegetable and Fruit Improvement Center have genetically modified a carrot which helps people absorb more calcium. From Science Daily:
"If you eat a serving of the modified carrot, you'd absorb 41 percent more calcium than from a regular carrot," said Dr. Jay Morris, lead author on the paper, a post doctorate researcher at Baylor College of Medicine in Houston.
However, on the flip side, too much calcium can cause these problems:
Hypercalcemia per se can result in fatigue, depression, confusion, anorexia, nausea, vomiting, constipation, pancreatitis or increased urination "Bones, stones, groans, and psychic moans" is a saying which will help you remember the signs and symptoms of hypercalcemia; if it is chronic it can result in urinary calculi (renal stones or bladder stones). Abnormal heart rhythms can result, and EKG findings of a short QT interval and a widened T wave suggest hypercalcemia. - Wikipedia
Researchers in New Zealand have now determined that calcium supplements are also associated with other health risks. From Reuters:

Calcium supplements may increase the risk of heart attack and stroke in healthy postmenopausal women, a study in New Zealand has found.

The women recruited had a mean age of 74 and had been postmenopausal for more than five years. Those who were receiving treatment for osteoporosis, already taking calcium supplements, or suffering any major ongoing disease were excluded.

Of the 1,471 participants, 732 were given calcium supplements and 739 given placebos. They were followed up every six months for five years. Researchers also checked hospital admissions and reviewed all death certificates for study participants to identify any unreported events.

Heart attacks were more common in the calcium group, with 31 women in that group suffering a total of 36 such events, while 21 women on placebo suffered 22 such events. More strokes were also seen in the calcium group, with 34 women suffering 37 such events, while 25 women on placebo suffered 26 such events.

Guitar Wizard: a video game with a real guitar


Move over Guitar Hero, here comes Guitar Wizard!

From Allegro Rainbow:
Guitar Wizard is an education-focused video game that teaches kids of all ages to read and play music. Guitar Wizard will be available for both PC and Mac and will come with a real Washburn guitar and a MIDI pickup. The game’s unique, patented, 4-step learning method allows anyone to learn to play a real guitar and read music in minutes! The software is also compatible with any MIDI guitar.

This is one of the many booths being publicized for the upcoming CES convention in Las Vegas, NV from January 7-10, 2008.

Simple, elegant solutions for overcrowded plugs

The first comes from Blast Magazine, and is one of those 'why didn't I think of that!' solutions to all those big fat plugs we try to squeeze onto the typical power strip. The Powramid's specs can be found here.







The second, by Belkin, is a headphone splitter on steroids. The Rockstar comes complete with 1 output jack and 5 variable input/output jacks, so you and your 4 closest friends can listen to your ipod, or other devices. More info at ilounge.
