Zubbles – Get Your Colored Bubbles

photo of blue colored bubble.

I first posted on this in 2005: Colored Bubbles. Now you can order your own via Zubbles. Colored Bubbles Have Landed (and Popped and Vanished)

Having solved the colored bubble dilemma, we spent most of 2006 trying to refine our dyes and the manufacturing process. We had invented several completely new dyes and a few derivatives of existing dyes. But the manufacturing process was long, tedious and expensive. It took three days just to make a few grams of each dye. It quickly became apparent that we needed to radically streamline the production process in order to have a viable product.
…
The complexities of the chemistry resembled a pharmaceutical more than a toy. So I enlisted the help of Gary Willingham, and the Belgium development team, at Fisher Scientific. Fisher is a pharmaceutical chemical manufacturer with the equipment and expertise needed to manufacture tons of our dyes.
…
Due to the complexities of the chemistry, Jamm decided to stay close to the production process and manufacture Zubbles in the US. The first bottles rolled off the line this week. Jamm presented me with the very first case of Zubbles. And it was a very strange feeling to finally hold the product in my hand—15 years after I mixed my first batch of dishwashing detergent and food coloring.

Being an entrepreneur is a challenge any time. When your product requires complex science and engineering that adds additional challenges. It is great to see this product is now available.

Jetman Jumps from Plane Then Into the Ocean

Yves Rossy’s attempt to fly 28 km across the the Strait of Gibraltar from Tangier in Morocco to Atlanterra in southern Spain fell short. He did make it about 15 km flying his jetwing before he ditched into the Atlantic. I posted about him before: Jetson Jetplane Over English Channel and Jetson Jetplane.

President Obama Speaks on Getting Students Excited About Science and Engineering

The President announces the “Educate to Innovate” initiative, a campaign to get students excited about pursuing careers in science, technology, engineering and mathematics. Quotes from President Obama from his speech – (see webcast above):

“As President, I believe that robotics can inspire young people to pursue science and engineering.”

“Now the hard truth is that for decades we’ve been losing ground. One assessment shows American 15-year-olds now rank 21st in science and 25th in math when compared to their peers around the world.”

“And today, I’m announcing that we’re going to have an annual science fair at the White House with the winners of national competitions in science and technology. If you win the NCAA championship, you come to the White House. Well, if you’re a young person and you’ve produced the best experiment or design, the best hardware or software, you ought to be recognized for that achievement, too. Scientists and engineers ought to stand side by side with athletes and entertainers as role models, and here at the White House we’re going to lead by example. We’re going to show young people how cool science can be.”

“improving education in math and science is about producing engineers and researchers and scientists and innovators who are going to help transform our economy and our lives for the better.”

Kids Not Clamoring for Engineering Careers

Engineering careers with experiences

Engineers are terribly misunderstood. Which might be one reason 85 percent of kids say “no way” to an engineering career. “The stereotype of the engineer is just wrong,” says Warren Miller, a retired Florida engineer who e-mailed me after I wrote about the short supply of workers in science and technology.

They think it’s “someone who is half-robot super genius” and “way more interested in machinery or circuitry than people.”
…
Part of the misunderstanding starts with adults who influence future workers. The survey found that only 20 percent of parents have encouraged or will encourage their children to consider an engineering career. More girls say their parents are likely to encourage them to become an actress than an engineer.
…
The National Science Foundation estimates a shortage of 70,000 engineers by 2010. To reverse the trend, we need to apply the engineer’s biggest tool: logic.

Based on the title of this blog you can guess I am in favor of engineers. Engineers can find great rewards in their careers from interesting work to high pay and leadership positions. In the modern world you need an understanding of science and engineering just to be a literate member of society.

Teenage Engineer’s Company Launches Safety Stair

Young engineer launches stair aid by Geoff Adams-Spink

A young woman from Sheffield has turned a GCSE coursework project into an award-winning stair-climbing device for older and disabled people. Ruth Amos has launched her StairSteady handrail at Naidex 2008 – the annual disability exhibition in Birmingham.

She told BBC News that she was inspired to create the device for the father of one of her teachers who had had a stroke. She won an award for her idea and has now set up a company to sell it. The StairSteady is a horizontal rail at 90 degrees to the wall or banister that people can hold on to as they go up or down stairs.
…
The invention was then entered for the Young Engineer for Britain competition and won first prize.

Great stuff. Innovation doesn’t have to be amazing technology. Finding solutions that make people’s lives better is the key. And then showing some entrepreneurship is great, Ruth setup her company when she was 16. I wish her luck.

Soft Morphing Robot Future

This webcast shows iRobot’s (Romba maker) prototypes for soft flexible robots. The robot uses “jamming” to morph the body which allows animal like locomotion and the ability to reshape the body to squeeze through small and difficult to navigate locations.

Engineering: Cellphone Microscope

UCLA Professor Aydogan Ozcan‘s invention (LUCAS) enables rapid counting and imaging of cells without using any lenses even within a working cell phone device. He placed cells directly on the imaging sensor of a cell phone. The imaging sensor captures a holographic image of the cells containing more information than a conventional microscope. The CelloPhone received a Wireless Innovations Award from Vodafone

a wireless health monitoring technology that runs on a regular cell-phone would significantly impact the global fight against infectious diseases in resource poor settings such as in Africa, parts of India, South-East Asia and South America.

The CelloPhone Project aims to develop a transformative solution to these global challenges by providing a revolutionary optical imaging platform that will be used to specifically analyze bodily fluids within a regular cell phone. Through wide-spread use of this innovative technology, the health care services in the developing countries will significantly be improved making a real impact in the life quality and life expectancy of millions.

For most bio-medical imaging applications, directly seeing the structure of the object is of paramount importance. This conventional way of thinking has been the driving motivation for the last few decades to build better microscopes with more powerful lenses or other advanced imaging apparatus. However, for imaging and monitoring of discrete particles such as cells or bacteria, there is a much better way of imaging that relies on detection of their shadow signatures. Technically, the shadow of a micro-object can be thought as a hologram that is based on interference of diffracted beams interacting with each cell. Quite contrary to the dark shadows that we are used to seeing in the macro-world (such as our own shadow on the wall), micro-scale shadows (or transmission holograms) contain an extremely rich source of quantified information regarding the spatial features of the micro-object of interest.

By making use of this new way of thinking, unlike conventional lens based imaging approaches, LUCAS does not utilize any lenses, microscope-objectives or other bulk optical components, and it can immediately monitor an ultra-large field of view by detecting the holographic shadow of cells or bacteria of interest on a chip. The holographic diffraction pattern of each cell, when imaged under special conditions, is extremely rich in terms of spatial information related to the state of the cell or bacteria. Through advanced signal processing tools that are running at a central computer station, the unique texture of these cell/bacteria holograms will enable highly specific and accurate medical diagnostics to be performed even in resource poor settings by utilizing the existing wireless networks.

This is another great example of engineers creating technologically appropriate solutions.

Researching Direct Brain Interfaces for Text Entry

Adam Wilson posted a status update on the social networking Web site Twitter — just by thinking about it. A UW-Madison biomedical engineering doctoral student, Wilson is among a growing group of researchers worldwide who aim to perfect a communication system for users whose bodies do not work, but whose brains function normally. Among those are people who have amyotrophic lateral sclerosis (ALS), brain-stem stroke or high spinal cord injury.

The interface consists, essentially, of a keyboard displayed on a computer screen. “The way this works is that all the letters come up, and each one of them flashes individually,” says Williams. “And what your brain does is, if you’re looking at the ‘R’ on the screen and all the other letters are flashing, nothing happens. But when the ‘R’ flashes, your brain says, ‘Hey, wait a minute. Something’s different about what I was just paying attention to.’ And you see a momentary change in brain activity.”

The system still is not very quick. However, as with texting, users improve as they practice using the interface. “I’ve seen people do up to eight characters per minute,” says Wilson.

Honda U3-X Personal Transport

Honda and Toyota continue to develop personal transport and personal robotics assistance products. While other car companies can barely stay in business Honda and Toyota not only are doing well (even if Toyota will lose money this year) they are investing in the future and pushing strong engineering programs. I must say the personal transportation devices seem less than awesome to me though this video does make the Honda U3-X seem reasonable – better than the Toyota Winglet looked.

Honda unveiled U3-X, a compact experimental device that fits comfortably between the rider’s legs, to provide free movement in all directions – forward, backward, side-to-side, and diagonally. Honda will continue research and development of the device including experiments in a real-world environment to verify the practicality of the device.

This new personal mobility device makes it possible to adjust speed and move, turn and stop in all directions when the rider leans the upper body to shift body weight. This was achieved through application of advanced technologies including Honda’s balance control technology, which was developed through the robotics research of ASIMO, Honda’s bipedal humanoid robot, and the world’s first omni-directional driving wheel system (Honda Omni Traction Drive System, or HOT Drive System), which enables movement in all directions, including not only forward and backward, but also directly to the right and left and diagonally. In addition, this compact size and one-wheel-drive personal mobility device was designed to be friendly to the user and people around it by making it easier for the rider to reach the ground from the footrest and placing the rider on roughly the same eye level as other people or pedestrians.
