DIY Friday: Etch-a-Sketch & Scooter

Friday, April 14th, 2006

As I’ve said before, I’m not really a DIY kinda guy. Putting together IKEA furniture and my kid’s toys are about as good as it gets. But I admire people who do roll up their sleeves and make stuff. So, every Friday I’m going to try and find a few cool DIY projects to feature here. 

Speaking of kids’ toys, by the way, I stumbled across a pretty impressive project involving a kid’s toy over at I Make Stuff, where the blogger interviewed a guy who usually makes "robots that kill other robots" but recently did something pretty cool with an Etch-a-Sketch.

I had one of these growing up, but could never make a decent picture with it. Little did I know that all I needed were some pulleys, foot pedals, and a laptop to control it all. But you still have to shake it to wipe out the picture. Check out the video podcast at I Make Stuff, recorded at Seattle Battle Bots IV, as well as  more pictures of the CNC controlled Etch-a-Sketch.

Oh, and if you’d prefer something that’s not only cool but useful as well, DIY Happy has a link to instructions on how to build your own Segway-like scooter. I had a scooter growing up too, but nothing like this. There’s video there as well, and details on the version 2 of the scooter includes an amusing picture of some people engaged in a game of Segway Polo.

When It Absolutely Positively Has to Get to Space

Friday, April 14th, 2006

Not that I’ll need that service any time soon, but apparently Masten Enterprises are the people to call if you need to send something into space. For a fee, they’ll blast your stuff into the stratosphere. There’s even a video of how it works.

The prices seem pretty reasonable at first glance. 

350 gram CanSat – $99
1 kg Custom Payload – $250
2 kg Custom Payload – $500
5 kg Custom Payload – $1250

If you’re like me you’ll need a translation. 

0.77 lbs – $99
2.20 lbs – $250
4.40 lbs – $500
11.02 lbs – $1250

Then again maybe not. Seems like a lot of money to send something ranging from the size of a soda can to a well-fed cat into space. And how do you get your stuff back once it’s up there? Or do you just send up stuff that you no longer need? And if so, this is better than throwing it away or recycling it how

It sounds like a cool idea, but unless someone can explain to me just how useful it is, my advice to anyone who has something they no longer need and want to send into space is pretty simple: hold a garage sale.

GPS Tracking for Parents

Thursday, April 13th, 2006

Before I had a kid of my own, I used to shake my head at parents who used "tethers," that looked like old fashioned telephone cords, to keep their toddlers from toddling off in public. Three years into parenthood, I haven’t succumbed to the "urge to tether" yet, but I’m a little less judgmental about the whole thing.

I have enough trouble keeping up with my three-year-old now. I’m already wondering how I’m going to keep up with him when he’s a teenager with enough subway fare to go where he wants. The answer is simple than I thought: GPS. If it can help find lost pets, it ought to work with kids too. So, though my little one isn’t big enough for a cell phone yet, I was relieved to read on Mobile Wireless News that Sprint just rolled a GPS-driven kid locator service for parents.

Using the Global Positioning System, the service allows parents to track up to four cell phones over the Internet or on their own wireless device. Parents can periodically ask the service to find the child’s phone, displaying the location on a road map.

Parents can also set alerts, automatically warning the parent if the child isn’t at a certain place, such as school or soccer practice, at a specific time.

The child’s phone also displays a text message, letting the child know they’ve been searched for and found.

Of course, there are other uses, like keeping track of elderly parents (as the article notes) or keeping tabs on a wandering spouse, which leads to charges that Big Brother is in the house.  I guess there’s two sides to every technology, and whether it’s used benevolently or not depends on whose pushing the buttons. But, as a parent, if kids can’t remember to be in the house when the streetlights come on, this seems like a pretty good way to remind them, when yelling down the street isn’t an option.

Apollo 13

It was yesterday. Did you remember? I didn’t until until Transterrestrial Musings reminded me, but I usually don’t remember anniversaries. At least this time I don’t have to buy flowers on my way home, but a movie night may be in order. 

Of Space Phlebotomy and Chipped Teeth

Tuesday, April 11th, 2006

Here’s something I hadn’t thought about. (And I’m willing to bet few people have.) Ever consider how many things us earthbound folks take for granted, but would require some additional thought in space?

Sure. Astronauts have to eat and sleep in space, along with all the other things they normally do on earth, but without the benefit of gravity.  According to New Scientist Space, simple procedures like getting blood samples are a little more complicated when human health emergencies arise in space. 

Space Needle

Taking blood from arteries can be crucial in diagnosing problems in health emergencies – but doing so in the microgravity of space is tricky and potentially dangerous.

Now researchers have come up with a potential solution – a thumb-sized gadget that collects a sample from the earlobe.

Blood is easiest to collect from veins, but this blood is on its way back to the heart and has been de-oxygenated and altered in the body’s tissues. This means it is not as useful for monitoring serious health problems as blood coming fresh from the heart in arteries.

"But the technique to collect blood from the artery is complicated and needs a lot of training," says Thais Russomano, at the Microgravity Laboratory of PUCRS University in Brazil. "It can also be painful and blood clots or infection can result. So it can be a bit dangerous to perform that in space."

So Russomano and her colleagues created the device to collect samples of "arterialised blood" from the earlobe. This serves as an accurate substitute for arterial blood. The system clips onto a subject’s earlobe and contains both a small cutting blade and a collection chamber, to ensure no blood can spill and contaminate the spacecraft. The device is operated with a twist and is said to be virtually painless.

Kinda gives the term "space needle" a whole new meaning doesn’t it? 

Maybe you should take it with a grain of salt, as New Scientist Space also reports that they were duped some art students who claimed to have invented a "cell phone tooth" by implanting a vibrating radio receiver in a human tooth.  So were a a few others, including Time magazine and Wired, the latter of which just exposed the fraud

Then again, maybe no one should be embarrassed by this. After all one person’s idea of a joke is often turns into someone else’s idea of "crazy enough to work." Scoble recently posted about a guy who implanted an RFID chip into his hand and posted a video about it.  (It’s been done before, of course.) And if you believe The Register, Belgian scientists have embedded RFID chips into — wait for it — human teeth. 

So, hoax or no, the "cellphone tooth" isn’t all that far fetched. And if it comes to pass, those who were duped before can claim "we always new it was possible" and claim the cutting edge.

NASA Goes to China?

Thursday, April 6th, 2006

The China story is getting more interesting. I only found out a couple of days ago that China has a space program, and some pretty ambitious plans to go along with it. At the time I wasn’t sure how serious the news was as far as the U.S. space program is concerned. Now I find out, via The Write Stuff again, that apparently it’s serious enough that NASA may send someone to China to check things out.

Chinese space officials have invited NASA Administrator Michael Griffin to visit their country in the fall, possibly as early as September.   

During an informal visit to NASA headquarters in Washington, April 3, Luo Ge, vice administrator of the China National Space Administration, met with Michael F. O’Brien, NASA associate administrator for external relations, to discuss a potential trip by Griffin to meet with Chinese space officials and visit their facilities, possibly as early as September.

“I made a joke with Mr. O’Brien that if we need to get married some day, we have to meet; otherwise we cannot get married,” Luo said in an interview here following his morning keynote speech April 5 at the 22nd National Space Symposium. Luo described the visit with O’Brien as “only a drop in” with two purposes:” to see an old friend” and to discuss Griffin visiting China.

Marriage proposals aside, that’s rather interesting news. Granted, it’s only an invitation, I haven’t heard whether it’s been accepted. But Lou did speak earlier about China’s willingness for space collaboration, and given Tom DeLay’s rather dire warning about the "space race" with China, it might be smart for NASA to at least give the Chinese program the once over; especially considering who else could be entering the "space race." 

If Matt Tompkins over at DefenseTech.Org is right when he says "Don’t Freak" over reports that China is set to overtake the U.S. in technology development, NASA may find it has nothing to worry about.  And with China concerns about its U.S. debt holdings, and  news that Iran is entering the space race too, some kind of U.S. – China partnership could be advantageous for both.

Mind you, I’m just a newbie who’s trying to sort all this stuff out. And I wouldn’t’ mind a little help.

China’s Sputnik?

Tuesday, April 4th, 2006

It’s gonna get crowded up there. In space, I mean. On the moon in particular. And the key to it all may be soon-to-be-former Congressman Tom DeLay. I thought it was down to the U.S. and Sweden in the latest lap of the "space race."  But it looks like there’s one more player entering the arena. I checked my RSS reader this afternoon, and found out via NASA Watch that China has plans for space exploration to the moon and beyond.

A top Chinese space official on Monday described China’s ambitious exploration plans, including robotic Moon missions starting next year.

Beyond Moon missions, including a flight to collect and return lunar samples to Earth in 2017, the Chinese space agency plans to develop a nonpolluting launch vehicle that can lift 55,000 pounds (25,000 kg) into orbit by 2010, said Luo Ge, a vice administrator at the Chinese National Space Administration.

"Space is a high-risk investment," Luo said through a translator at the Center for Strategic and International Studies, a Washington think tank. "China as a developing country is limited and constrained by its funding for more ambitious programs."

But Luo says China has an edge because of the progress of its space program, the country’s "openness" — citing its work with countries like Russia, Nigeria, and Brazil — and because the U.S. has grown more closed since the 1990s. The Write Stuff, space blog of the Orlando Sentinel’, points to a story that repeats Luo’s claims and notes the successes of China’s space program, including a manned spaceflight last October. 

But is there anything to China’s claims? And How does Tom DeLay figure into all of this? 

Jeff of Space Politics reminds us that none other than Tom Delay warned just a week ago that the U.S. is in a "space race" with China, and even called China’s space program "a 21st century Sputnik moment"

I’m not sure I buy that comparison, as it sounds like a bit of hyperbole to me. After all, Luo even noted that China’s $500 space budget is barely bus fare compared to NASA’s $16.6 billion. But then again NASA is losing a powerful backer in Tom Delay, and having to pinch pennies for the moon mission even as scientists are clamoring for more

Plus Jeff also speculates that, since he called for a special oversight hearing on NASA’s human space space program during a congressional hearing last week, the Chinese space program might be one reason for DeLay’s 2-month "delay" in actually leaving office. Maybe ensuring NASA stays well head of China’s"sputnik" will be DeLay’s swan song.

I suppose Jeff could be right. After all, just last week I thought Sweden was America’s biggest competitor in space. They don’t call me NooBee (i.e. "newbie) for nothin’, folks.

A Hard Knock Life for Satellites

Friday, March 31st, 2006

I’m probably giving away my age when I say this, but I remember when our television had a "rabbit ear" antenna, and adjusting the picture just meant moving the "ears" around. Later we had an antenna on the roof. Adjusting the picture meant someone had to climb a ladder to the roof, while someone else yelled out of a window until the picture was clear. Then there was cable. If we lost the signal, we called the cable company and waited.

Now we have satellite TV, and we rarely lose a the signal — except for occasionally during a storm, when it flickers on and off briefly before returning. If we have snow, it can interrupt the signal if it piles up on the dish, but that just means a quick trip to the back yard to brush it off. The dish in the back yard, however, is just a receiver; pointing at at a satellite so high up that a ladder on the roof doesn’t begin to do the trick. So, what happens if a satellite gets bonked by an asteroid or other random space junk?

Well, you lose the signal, which is what happened to a lot of Russians this week when a telecom satellite failed after a "sudden impact" shut down its thermal control, causing it to end up in space disposal orbit.  (Yeah. I didn’t know what that meant either. Apparently there’s a whole part of space where satellites go to die. Who knew?)  New Zealand had an outage too, due to loss of pointing control.  (Another hard knock?) A European satellite got bonked in 1993 when the earth passed through a trail of comet dust. 

So, what to do? Some people are trying to predict problems, and others are working on better materials. (What can withstand getting smacked by an asteroid?) And some are focusing on better monitoring and forecasting of sunspots and space weather (space weather?), which apparently can also cause problems for satellites. 

I can’t say how it all works. I just hope it keeps working. I don’t want to miss any of my favorite shows, and I don’t want to have to climb any higher than the roof.

iPod-from-Space Mystery Unfolds?

Wednesday, March 29th, 2006

After getting some comments from our readers on the iPod-from-Space post, concerning the accuracy of the dates in the Terrabyte screenshot, we dropped an email to TerraServers to see if we could get any further answers. Here’s what they sent us:

You can’t get the whole planet shot all in one day, so it is made up of various collection dates in 1999. When you have a large date range over a big mosaic like this, the company that took it will often just give the month or year taken. In cases like this, to specify a date, we use the first of the month or first of the year. So, all of the 1/1/1999 pictures would be made up of shots taken during 1999 or possibly some in 1998 or 2000. They’d probably go with the year with the majority. This 15m satellite mosaic covers most or all of the earth’s surface and is the last full collection that we know of. That’s partly because one of the Landsat satellites failed or crashed a couple of years back. It is the main baseline imagery that us and the rest of the major imagery sites use to show basic coverage worldwide. That’s why you’ll see the same picture between us because it’s all coming from the same original imagery.

I was able to pick off the coordinates from the image at full size on Flickr and get to it on our site. My best guess from looking at the area just north of it is that it’s part of a strip mining operation. The “screen” of the iPod might be a big holding pond or quarry pond

 Anywhere from 1998 to 2000, huh? Strip mine? Quarry pond? Sounds feasible, given the original post, but still doesn’t nail down an absolute date. So perhaps it still remains a mystery.
