No Lens Lasers
Posted on 06.22.09 by John @ 5:52 pm

No lens laser stack

Impressive, technology like this might lead to all sorts of wonderful things. I’m thinking video projectors that use lasers and that have no moving parts of nasty super hot lamps (just super hot lasers, have to work on that…)

Researchers have now demonstrated a plasmonic collimator that utilizes grooves etched directly into the semiconductor laser facet. If the technique is adopted — Harvard University has applied for a patent on the process — then semiconductor lasers can be downsized to a bare die without a lens.

Lasers need lenses no more

Coming Soon, Eagle Eye Vision for the Blind
Posted on 04.03.09 by John @ 7:31 pm

Telescopic eye implantWell not quite the blind and not quite ‘Eagle Eye‘ vision. I refer to the way cool Bionic Dollar Man action figure (NOT a doll I tell ya!) that had a wee telescope in Steve’s head. However, the idea is pretty close. There is a new medical device that can return some sight to people who suffer from macular degeneration. To give a little bit of an idea what it’s like to have MD make two fists and put them in front of your eyes so they block most of your field of view. Now keep them in the center of your vision wherever your eyes point at. Not fun is it. The 4mm long telescope fits in the eye where the natural lens would be and projects a magnified image of what the person is looking at on to their retina.

“These cells are normally involved in peripheral vision and normally generate low-resolution visual information compared to the macula cells–you can’t read a sign in your periphery, for example. But magnifying the image also has the advantage of making it easier for the cells to interpret.”
… “The device is implanted in only one eye–patients use this eye for detailed vision and the untreated eye for peripheral vision. That takes some getting used to, says Peli. “Instead of using two parts of the same eye, they must switch between two eyes; if they see someone coming but can’t tell who it is, they need to switch to other eye.”"

Even a low level of vision is better than none at all. Should be available as soon as the FDA approves it.

When Satellites Collide
Posted on 02.12.09 by John @ 7:22 am

Like a scene from the Japanese TV series “Planetes“, a Russian and US satellite have collided in orbit. Early in February a non functional Russian military satellite (Kosmos 2251) and a US Iridium communications satellite occurred temporarily disrupting the Iridium communications network. An on orbit spare will be brought into service within the next 30 days. So far this isi the first accident of it’s kind, where a satellites has struck another satellite and not just orbital debris (paint chips, fuel tanks, etc) hitting working space hardware. There was that Chinese missile test where they destroyed a non functional weather bird but that was intentional (and also caused quite a mes up there). Hopefully the junk left from the recent accident will burn up, if not it will become part of the cloud of over 17,000 objects that are currently tracked by ground stations.

Original story:
Russian and US satellites collide

Mechanical TV, Steampunk Style
Posted on 01.20.09 by John @ 7:33 am

Steampunk Mechanical TV
This is a wonderful project to build a working Baird mechanical television (televisor) that uses, among other things, a real working steam engine and a record as it’s ‘Nipkow disk’. It’s a great idea, Steampunk with real steam, I can’t wait to see some stills from it.

Mechanical TV has been an interest of mine for years now. The very idea that in  the primordial age of television the best solution was a big spinning disk and a flickering neon lamp. I have a model of a Baird Televisior that I built from a kit. It benefits from modern electronic timing and low voltage parts (LEDS not neon bulbs). It clearly works but only produces the most rudimentry of moving images. I have transcoded a few video clips to play on it (it comes with an audio CD of video sequences) and for what it is I’m impressed. I still want to build a camera that I can use to display live motion on it. Perhaps I’ll design it with a Steampunk theme.

DIY Plane from a Broken Helicopter
Posted on 01.01.09 by John @ 8:56 pm

I had a toy helicopter that had lost it’s tail rotor in an unfortunate accident. I didn’t want to part with it because the main rotor still spun and heck it’s a remote control helicopter. I proceeded to turn the once state of the art in toy chopper technology (OK, once of state of the art) into a regular airplane. This is a photset of my ‘proof of concept’ adventure.

Thinking About the Bomb, 24/7
Posted on 12.25.08 by John @ 9:55 am

gun-type fission weapon - WikipediaThis is quite the facinating story about a man named John Coster-Mullen that while driving his semi truck attempts to plumb the inner workings of America’s first atomic bomb named ‘Little Boy’. Sounds like a strange hobby to some but to me it represents a pure ‘knowledge for the sake of knowledge’ motivation that is lacking in today’s world. Call me morbid but being able to get down to the nuts and bolts of one of the most destructive devices mankind has ever constructed is an amazing achievement.

Have you hurled today?
Posted on 12.21.08 by John @ 6:15 pm

Catapult Nothing but fun family time here. Everyone loves to build tiny replicas of Medieval siege machines! Let’s not forget that it’s also a great way to expand your mind…

A catapult project gives students a chance to see that science and engineering really can be fun, and it’s a lot more than just numbers on paper. The real payoff for an engineer is in the field, where she can see and enjoy the results of her ingenuity. And it may seem counterintuitive, but engineering projects not only help kids learn math and science, they are also great at getting kids back outdoors, away from the massive over-exposure to video games, TV and the Internet.

Hearing Radio Waves
Posted on 12.21.08 by John @ 6:02 pm

Nanoradio receiver
Quite an astounding bit of engineering.


We have constructed a fully functional, fully integrated radio receiver, orders-of-magnitude smaller than any previous radio, from a single carbon nanotube. The single nanotube serves, at once, as all major components of a radio: antenna, tuner, amplifier, and demodulator. Moreover, the antenna and tuner are implemented in a radically different manner than traditional radios, receiving signals via high frequency mechanical vibrations of the nanotube rather than through traditional electrical means.

Hubble Spots New Planet
Posted on 11.13.08 by John @ 6:04 pm

Well done Hubble!

NASA’s Hubble Space Telescope has taken the first visible-light snapshot of a planet circling another star. The team of astronomers who made the discovery includes researchers at NASA’s Jet Propulsion Laboratory, Pasadena, Calif.
Estimated to be no more than three times Jupiter’s mass, the planet, called Fomalhaut b, orbits the bright southern star Fomalhaut, located 25 light-years away in the constellation Piscis Australis, or the “Southern Fish.”

Tape + Vacuum = X-rays?
Posted on 10.22.08 by John @ 9:03 pm

Simply cool, who would have thought you could get x-rays out of tape? Chalk one up for triboluminescence!

It turns out that if you peel the popular adhesive tape off its roll in a vacuum chamber, it emits X-rays. The researchers even made an X-ray image of one of their fingers.

Silicon Camera That Mimics Mammalian Vision
Posted on 10.05.08 by John @ 6:20 pm

Curved cameraThis is quite an impressive achievement if you ask me.

Conventional cameras use a curved lens to focus an image onto a flat surface where the light is captured either by film or by digital sensors. However, focusing light from a curved lens onto a flat surface distorts the image, necessitating a series of other lenses that reduce the distortion but tend to increase the bulk and cost of a device.

Now You’re Cooking With … USB?
Posted on 07.16.08 by John @ 6:41 pm

Cooking with USB power Remembering that your typical USB port delivers 2.5 W doing anything other than lighting up a novelty hub or a clever little tree is about all you can do. Not quite. A clever fellow in Japan set out to prove this wrong. By using six five port USB expansion cards he has upped the thermal output from a wimpy 2.5 W to a respectable 75W! Oh yes, you can see where this is going. This looks like this is his second attempt at computer assisted gastronomy, he tried to cook an egg before. This time he succeeded in frying some beef rib meat (Sukiyaki anyone?) Good thing he has improved his design so we can all follow in his footsteps and … er, well we can imagine that we will follow in his footsteps, and be cooking a tasty dinner while leveling up in WoW.

Bankquest: Fight your way to riches
Posted on 06.21.08 by John @ 9:59 pm


This is a clever way to get kids in the habit of saving their money. It’s a traditional piggybank with a twist, the more you save the more gold your little character in the RPG game on the front gets to spend. Think of Tamagotchi that eats quarters. You can save around 50,000 yen (about $500US) so it’s a pretty good deal for a kid. Heck, good for an adult too because the interest rates in Japan are .5 %.

The Repeater
Posted on 05.14.08 by John @ 8:29 pm

Fish
Ah, the amazing power of biological evolution. How this simplicity escapes some people I don’t know.

Here’s an evolutionist’s dream: 10,000 planet Earths, starting from the same point at the same time, and left to their own devices for four and a half billion years. What would happen? Could you go on safari from one planet to the next seeing an endless procession of wildly different organisms? Or would many of the planets be home to life forms that are broadly similar?

BattleBots on ESPN in ‘08?
Posted on 03.11.08 by John @ 7:57 pm

Looks like the sound of gnashing gears and grinding steel may once again grace the television sets of America. Noted sports cable network ESPN has been talking to BattleBots about a possible hook up later this summer. I for one am looking forward to it, nothing quite like seeing two hundred plus pound remote controlled cars beating the crud out of each other. Ah, technology…
