Change

Two things just occurred to me. First, I haven’t heard anything about the war lately. I don’t have cable, and am fine with being out of “the know,” and this has been my situation for the last two years. During the first of those two years, wherever there was media (inescapable) I was reminded of what a horrible war we’re waging, the constant death tally, and horror stories of individuals involved in the war, and reports of negative public opinions of the war and the president. I was eating Apple Cinnamon Cheerios just now and thought to myself “are we still at war?” This is a ridiculous question, of course, but then I realized I haven’t heard anything about it in like forever. Has anything changed? I know Tiger Woods is a big deal, and something about health care reform… but um…. war still bad, right? Are we still sending more troops over there? But its ok now cuz Barack is sending them not Bush? I don’t even pretend to know what I’m talking about here, but I feel like there is some value in this perspective.

Second, I wonder if anyone would read a blog post even though I haven’t posted in like nine months.

idiot zoo

about midnight I was patrolling the facility because it is THE crazy party night of the year. about 50 feet down the road I saw a car pulled over with a kid barfing on the sidewalk. Now, I’m listening to the scanner as three ambulances and a police car respond to an incident at the apartments next door. we saw one dude go in the ambulance in handcuffs. I’m hearing a continuous stream of call ins.. right now… Robert Collins, 23, no warrants, disorderly conduct…. somebody throwing bear bottles at a frat house… a 5 person fight in the street, the police arrived, everybody ran… another disorderly….somebody fell through a sliding glass door, 6 inch gash into shoulder… somebody hit by a car (oh, that’s by our old place)…

Nothing I am witnessing around me right now looks like fun. I’ve never understood it, and if my kids are ever like this I don’t think I will understand it then, either. What is the appeal?

Mars Rocks

I would like to make a better web-presents for the two builds I was involved with recently, but for now, for the sake of having pictures available, here is one of them.

Mars Rocks competition, the Claw.   It won the “Shock and Awe” award.  I just made that up.  It woulda won first overall if ___________!  But that’s what all the losers say.  Achiles, our other build, did win first overall.  Those pictures are soon to come.

That welded metal piece towards the front was added for ballast.  It had to go over obstacles, and in order for it to lean forward and go over them, it needed some weight up front.  It is the only part on the build that doesn’t fall within 10/1000 inch specifications.  and its ugly.  We took it off after finishing the competition, works fine without it.  The point of the bot is to grab rocks, put them in the hopper, transport them to a target area, and drop them there.  video soon.

Stuff wanting

I just read my friend Joal’s blog, and now I am inspired. I often find myself jealous of some people’s ability to be happy without requiring tons of gadgetry and stuff. I mean, I am happy without stuff, but I’m happier with it. What I’m looking forward to after graduating from college is having kids, and having more stuff. I plan to buy stuff with my money. Yeah, we’ll save some and invest some more, and pay off student loans, but I’m more excited about the things I’ll get to have. I want an xbox360, a nice lcd tv, a cool cell phone, some more RC toys, and tools in the garage (and I mean tools - lathe, mill, waterjet, welding stuff, presses, punches, dies, casting and forging equipment, EVERYTHING). I want a nice car and a big house.
Joal’s blog is mainly about time spent with his kids and Elizabeth, memorable moments, deep and gushy stuff. Its great! I get a sense of his value system, and an appreciation of relationships and community. I do love the outdoors, and I love camping and hiking with Holly. Maybe instead of totally repenting of my materialism I can just sort of morph it into something more family oriented instead of self oriented. Yes, instead I’ll covet all the coolest baby-monitoring electronics, the most high tech car-seat, and stuff like rafting, boating, hiking, and camping equipment.

Meditation of my Heart

Being around college guys in the ME school has had positive and negative influences on me.   For some reason, the people here are so much more foul and crude than students at the community college I left two yeas ago.  Here, I try to associate more closely with people I can be comfortable conversing with, but the rest are inescapable.  Recently I have caught myself thinking things I wouldn’t have two years ago.   Keeping my mind pure and positive is an increasingly difficult challenge.

On Wednesday it came to a point, I said a silent prayer and resolved to change.  The next day I had a song repeating in my mind.  I had forgotten about my resolve, the only thing that cropped up in my mind yesterday was this little tune from a Marley song.  I sang it in my head all day, or quietly as one does while walking through an empty hallway or in the car, without thinking about it at all.  it wasn’t until last night probably in the early hours of this morning as I was doing homework at the kitchen table and mouthing the words to the song, that I stopped what I was doing and recognized what was going on.  I had been singing it mindlessly all day but I stopped and thought about the words for the first time, I was shocked.

“Let the words of my mouth, and the meditation of my heart be acceptible in thy sight, oh Verai!”

Bob Marley - By The Rivers of Babylon

God and Marley

It took the group effort of God and Bob Marley to get this verse from Psalm 19 into my head.  What a blessing!  It reminded me immediately of the “Footprints in the Sand” story.  I didn’t know God was helping me all day, but he truly was.  I remembered that God is mindful of me and my little daily challenges.  Also that I am not left on my own in the struggle to progress in purity and all else.  Prayers are answered and anyone can call upon God to add strength to their efforts.

I started listening to Regae on my mission in Baltimore. I had a companion who insisted and I came to like it a lot.  A lot of current regae offerings are more like crap I mean rap.  But the old-school stuff is almost all spiritual in nature, or political.  Anyway, I like it.  Matisyahu is a relatively new face in the scene of traditional style regae.  I like him, too.

Wisdom Teeth Extraction

Its official.  They’re gone.  Well, they’re in the bathroom.  Dr. Morrison gave them back to me in a high-tech little baggy that probably cost $250.  I thought of making a charm necklace from the bones, but to work it would take a matching death or wicca themed wardrobe which I sadly lack.  And I’m not ready for that arena of social interactions.  We tried throwing the bones on the ground to see what they could tell us.  Nothing.  So they’re in the fancy baggy in the bathroom.  Maybe I could make a christmas nut-cracker and use the teeth for the nut-cracking mechanism.  Maybe a thumb ring with a wisdom-tooth center peice.  OOH, if I had a lip ring I could put the wisdom tooth as a charm on the ring.  Then, some other exccentric types would extrapolate some kind of deeper meaning from the thing.  Any other ideas?

From the few witnesses of my coming-to stages after the surgery, I’ve heard that I was a bit loopy. I don’t think I was as loopy as this kid, though.  Wow.

Need to Assembly in 2 days

The Live Shot shows the RC Car not quite assembled.

The Live Shot shows the RC Car not quite assembled.

This is why I love solid modeling. We needed a way to secure the battery to the RC Car. I went home, dreamt it up on the Solidworks, then emailed the file to the shop at school. They cut the parts with a water-jet out of 0.25 inch 2021 aluminum and I picked them up in two days. After about 20 minutes more of machining, it assembled exactly as designed. I love it when stuff works. More than that, this specific battery holder did not exist before I thought it up. This is a fairly simple design, but exemplifies that really anything is possible with the right resources. I happen to have a water-jet at my disposal, and it is the cheapest way to fabricate parts, cost is always a factor. I have WAY more elaborate projects in the making, but cannot post them here. They are for a competition and I can’t risk letting the other teams sneak peak at. Will post in the Spring.

Hotdog Jacob’s ladder

Someone left a small neon sign at the facility, so I took it apart.  I knew it would be cool.  I wasn’t disappointed.  I have to find a way to get this cordless.

below is a picture of me trying to cook lunch.  Even with tens of thousands of volts going through this hot dog, there is not enough current flowing through the dog to heat it up.

It runs off a 12 Volt power supply with a max current of .5 Amps.  So this circuit ups the voltage and lowers the current, but it can still only max out at Power = voltage*current = 6 Watts.  To give it a good try, I could adjust the hot-dog-electrical-resistance to match the impedance of the circuit to get all those Watts going through the dog, but I still don’t know if that would ever cook it.  To calculate that, I’d need some thermal properties of the hot dog, and I’m just not sure they’ve been measured.

However, I do know that plugging a hot dog into a wall socket does cook it. I’m guessing that’s around 1000-2000 Watts.  However, the salty juices in the dog tend to undergo electrolysis around the terminals.  The Hydrogen floats off, but the residual oxides taste really nasty.

Here is more fun with a hotdog and I’m guessing about 60,000 volts.

Is This True?

Our Tax System Explained: “Bar Stool Economics”

Suppose that every day, ten men go out for beer and the bill for all ten
comes to $100. If they paid their bill the way we pay our taxes, it would go
something like this:

The first four men (The poorest) would pay nothing.

The fifth would pay $1.

The sixth would pay $3.

The seventh would pay $7.

The eighth would pay $12.

The ninth would pay $18.

The tenth man (the richest) would pay $59.

So, that’s what they decided to do.

The ten men drank in the bar every day and seemed quite happy with the
arrangement, until one day, the owner threw them a curve. “Since you are all
such good customers,” he said, “I’m going to reduce the cost of your daily
beer by $20.” Drinks for the ten now cost just $80.

The group still wanted to pay their bill the way we pay our taxes so the
first four men were unaffected. They would still drink for free.

But what about the other six men - the paying customers? How could they
divide the $20 windfall so that everyone would get his ‘fair share?’ They
realized that $20 divided by six is $3.33. But if they subtracted that from
everybody’s share, then the fifth man and the sixth man would each end up
being paid to drink his beer. So, the bar owner suggested that it would be
fair to reduce each man’s bill by roughly the same amount, and he proceeded
to work out the amounts each should pay.

And so:

The fifth man, like the first four, now paid nothing (100% savings).

The sixth now paid $2 instead of $3 (33%savings).

The seventh now pay $5 instead of $7 (28%savings).

The eighth now paid $9 instead of $12 (25% savings).

The ninth now paid $14 instead of $18 (22% savings).

The tenth now paid $49 instead of $59 (16% savings).

Each of the six was better off than before. And the first four continued to
drink for free. But once outside the restaurant, the men began to compare
their savings.

“I only got a dollar out of the $20,”declared the sixth man. He pointed to
the tenth man,” but he got $10!” “Yeah, that’s right,” exclaimed the fifth
man. “I only saved a dollar, too It’s unfair that he got ten times more than
I!” “That’s true!!” shouted the seventh man. “Why should he get $10 back
when I got only two? The wealthy get all the breaks!” “Wait a minute,”
yelled the first four men in unison. “We didn’t get anything at all. The
system exploits the poor!”

The nine men surrounded the tenth and beat him up.

The next night the tenth man didn’t show up for drinks, so the nine sat down
and had beers without him. But when it came time to pay the bill, they
discovered something important. They didn’t have enough money between all of
them for even half of the bill!

And that, ladies and gentlemen, journalists and college professors, is how
our tax system works. The people who pay the highest taxes get the most
benefit from a tax reduction. Tax them too much, attack them for being
wealthy, and they just may not show up anymore. In fact, they might start
drinking overseas where the atmosphere is somewhat friendlier.

David R. Kamerschen, Ph.D.
Professor of Economics University of Georgia

As you can see, that analogy was reported to have been written by this economics professor, but I have checked the reference, and he denies ever writing it.  Apparently David R. Kamerschen, a professor of Economics at the University of Georgia is also sighted as the author in other Internet publications, but he denies authorship as well.  The true author is unknown.  The real question I’m throwing out there is: Does anyone know enough about taxes or economics to know whether this is a good analogy?

In Search of the perfect Zom Glo

baldy
baldy

From all my studies, this is the closest I’ve gotten to reproducing the perfect Zom Glo (minus hair).  I don’t know if there can be a perfect one.  Even if every Zom Glo has its subtle differences that make it individual, I am convinced that someone may be able to capture the “characteristic model,” or the “average” Zom Glo.  If anyone can help move this project along, please feel free to contribute a sketch or tips.  Thanks!
