You Might Be A Dinosaur If …

Here are ten reasons you might be a dinosaur.

  1. You have no tattoos and no desire to get one.
  2. The thought of metal studs piercing your tongue, nipples, or genitals gives you the heebie jeebies.
  3. You’ve actually used the term heebie jeebies in conversation.
  4. You think a cell phone is primarily for making phone calls.
  5. You still use email.
  6. Your music collection is on CDs.
  7. You think “reality television” is stupid.
  8. You’re mystified how a pair of jeans can cost $600.
  9. You look at your wristwatch when you want to know the time.
  10. Each day you seem to become a little more invisible to waiters, waitresses, salespeople, and everyone under age 35.

Number of reasons that apply to you:

0 – 3: Party on, dude!

4 – 7: You’re another day older and deeper in debt.

8 – 10: Welcome to Medicare!

The C.A.T. Vortex

Just to show you I am aware of current events, I admit to being sucked into the Casey Anthony Trial television drama reality show vortex. It happened the weekend of the 4th. It was so freakin’ hot outside – heat index above 100° F each day – and the A/C felt so good, and my recliner was so comfy. I sat down in front of the TV and turned on one of the cable news channels – CNN, I think – and there was the courtroom, and closing arguments were about to begin.

I didn’t follow the Anthony case for the last three years, but I was aware of it. I knew the names Casey Anthony and Caylee Anthony, but I was never sure which was the tot and which was the mom. Now the trial was culminating; the prosecutor was ready to give his closing statement, after which the defense would give their closing statement, after which the prosecutor would get another shot with a rebuttal.

As I had done the previous three years whenever I inadvertently tuned into the Anthony drama, I changed the channel. I switched to HLN. There was the courtroom again. I switched the channel to MSNBC, only to see the courtroom again. I switched to Fox News but alas, they were showing the courtoom drama, too. I know when to give up. I decided to watch the lawyers for a while.

After watching both the prosecution’s closing statement and the defense’s closing statement, I was glad not to be a juror on that case. On the one hand, the timeline of events and Casey’s behavior pointed to her as probably being responsible in some way for Caylee’s death. On the other hand, there were many important questions left unanswered. How did Caylee die? What was the cause of death? Was it suffocation by duct tape? Was it poisoning by chloroform? Was it drowning? Was it something else? No one knew. All they had was speculation. When did Caylee die? Dunno. Where did Caylee die? Dunno. Why did Caylee die? Dunno. Just speculation.

In 1692 and 1693, the people of Salem, Massachusetts, conducted what has come to be known as the Salem witch trials. Accused of witchcraft, and being found guilty at trial, fourteen women and five men were executed by hanging. An 80 year old man who refused to enter a plea was crushed to death under heavy stones. At least five more people died while in prison.

The important thing to note here is that the people who sat on the juries were swept up in the mob hysteria of the day. They listened to some very flaky evidence which convinced them that the accused were guilty. They were damn sure those people were witches. And they were wrong. They executed – murdered – innocent people.

Today we know how important it is to judge a person guilty only through the use of well-documented evidence that is allowed into the trial. We don’t vote guilty because we have passionate feelings about the case or about the defendant. We don’t vote guilty because we think we know what happened. We vote guilty when we have proof of guilt beyond any reasonable doubt. And when no one can prove how or where or when the victim died, there is reasonable doubt that a crime has been committed. Going dancing doesn’t prove you murdered someone. Getting a tattoo doesn’t prove you’re a murderer. Not even having a dead body in your car, if that is what happened, can prove that you murdered someone.

Maybe Casey killed her daughter and got away with murder. But maybe she didn’t. And that is why the jury returned a not guilty verdict. They knew it would be an unpopular verdict. The media had tried and convicted Casey long before the trial began. What happened in the media is analogous to the mob hysteria that gripped Salem in 1692. Fortunately for our system of justice, cooler heads prevailed. The jury didn’t listen to the TV pundits, they looked at the evidence. And in this case, the evidence didn’t prove a murder was committed, much less prove who was responsible.

HDTV Action

My flat screen TV has been acting up. It’s been taking longer and longer to turn on, during which time the green power LED just blinks on, off … on, off ... on, off. It’s only about four years old. Am I the only one who thinks a thousand dollar TV should last longer than four years?

It has a good picture when it’s working but it takes 10 to 15 minutes to turn on. I began just leaving it on 24 - 7. After a few weeks of doing that, I decided to take action: fix it or replace it. I knew the most likely cause of this malfunction was a bad electrolytic capacitor in the power supply.

Step 1 – Pull the TV away from the corner of the room and disconnect the cables. Remove two screws and slide the TV up and off its stand.
Step 2 – Place the TV screen-side down on a table and remove the speaker bar attached at the bottom edge of the case. Then remove a crap-load of little screws and the back cover comes off. It takes 15 minutes to get all that done.
Step 3 – after removing still more screws, disconnecting cables, and peeling back metal foil tape, I’m able to flip the center box over. The power supply board is on the left.
This is a closer view of the solder-side (bottom) of the power supply board.

This is the component side of the power supply board. It’s difficult to see in this image, but there is an electrolytic capacitor near the top right corner of the board, just above the transformer on the right, that has swelled and vented.

This is a closeup view of the bad capacitor. It’s in the center of the image, and the electrolyte being vented is black. The usual cause of this kind of failure is over-voltage. This cap is rated 2200µF/25VDC. I went to Radio Shack and bought a replacement. I wanted a 2200µF and I wanted to bump up the working voltage. The Shack didn’t have a radial lead cap in the value I needed, but I was able get an axial lead cap rated 2200µF/35VDC.

Fortunately, there was room to install the axial lead capacitor where the radial lead cap had been located. I soldered it in place.

I put everything back together and turned on the TV. It works great. When I push the power button on the remote, I have picture and sound in about eight seconds. The repair job took 90 minutes, not counting the trip to the store to buy the replacement part, and cost less than five dollars.

Biker Invasion

My small Virginia city has been invaded by a biker gang. They’ve just about taken over the town. Everywhere you go: bikers and more bikers. I was documenting the invasion with my point-and-shoot when there was a kerfuffle behind me. Carey’s dogs (she had them on leashes) were attacked (almost, anyway) by what looked like, and might possibly be, a roaming gang of rogue, non-leashed biker dogs.

How many bikers are there in this gang, you ask. I didn’t count, but it had to be thousands. At one point, I walked home, ate dinner, watched the 6:30 news, then walked back to the main drag and the biker gang was still streaming into town. Carey was still there with her dogs. She has two schnauzers she is training to protect her home from rogue bikers and their little dogs, and she wanted them to see the gang in action.

The bikers seem friendly enough, so far. But just in case … if you don’t see any more blog posts from me, you’d better send help.

Changing World

It’s late night and I’m watching Live From the Artists Den on PBS. Tonight Grace Potter and the Nocturnals are performing from New York’s Bryant Park. I like Grace Potter. Grace can belt out a song. Plus, Grace is gorgeous. How gorgeous? Imagine: if Kaley Cuoco could sing and play the Hammond B3, Fender Rhodes, Wurlitzer Electric Piano and electric and acoustic guitars. And not to put too fine a point on it, but Grace has great legs, as she well knows. (Ever seen Grace wear an outfit that didn’t show off her legs? No.)  But tonight Grace and her bass player Catherine Popper are competing to see who can show more leg. And Catherine is winning. But never mind that. I’m writing about something else.

Earlier this this evening I left my house to walk the tree-lined streets of my neighborhood. The setting sun was already at the horizon and dusk was falling. Birds twittered in the trees and the smell of honeysuckle floated on the evening air. It was almost like an evening from long ago. Almost, but not. I could hear girls shouting and hollering a block away. I rounded the block and passed a group of teen girls talking to each other. They looked to be in the 13 to 15 age range. As I walked past them I caught part of their conversation. It was fuckin’ this and fuckin’ that. One girl loudly proclaimed to the neighborhood, “I hate it when somebody takes my fuckin’ cell phone and fuckin’ calls somebody …” And on it went. (I wondered, “Do you kiss your mama with that mouth?”)  A shrill rant by someone’s little darlin’. I’ve heard plenty of profanity. My old man’s favorite was “goddamn” and he used it liberally. But at least he used it at home and at work, not in public places. He never used profanity on the street for the neighbors to hear, or in restaurants, or around strangers. My mother often told him that profanity was a sign of a poor vocabulary. Maybe so. But today’s casual and public use of profanity is a sign of something else.

Anyway, I got home and turned on the TV. The local news was telling me about a beloved and respected local teacher (male) who was just arrested for having Internet sex with a girl younger than sixteen. Everyone in his neighborhood (at least, everyone they put on the air) claims to be shocked. Shocked! I didn’t know the man but I wouldn’t have been shocked. Heck, teachers having sex with students is so prevalent these days it’s almost trendy.

The “Tea Party” people say they want to take back their country. I have bad news for them. The country they want to take back is long gone. It’s blowin’ in the wind now.

The Cow That Thinks It’s A Horse

A 15 year old German girl wanted a horse but her parents said “No.” So she put a bridle on one of the family’s cows and voilà: a show cow.

The Last Shuttle

Atlantis, America’s last space shuttle, is being rolled out to launch pad 39A. (Click the image below for a larger photo.)

The claim is that they (the shuttles) are getting old and therefore unsafe. The way I see it: the technology is getting mature; we’ve found most of the gotchas associated with flying space shuttles. We know about O-rings and cold temperatures; we know about foam insulation hitting the orbiter during launch. So actually, flying a shuttle should be safer now than ever. We should be building more shuttles, better shuttles, with new materials and better computers.

Shuttle Atlantis (launchphotography.com)

At left: the shuttle Atlantis with booster rockets and external fuel tank is sitting on the Mobile Launcher Platform which in turn is being carried on a crawler-transporter. More shuttle photos can be found at launchphotography.com.

Fully loaded, the top speed of the crawler-transporter is one mile per hour. Because of Federal regulations, the driver must wear a seat belt. Safety first.

I can’t think of a more boring journey than driving at one mile per hour for however many hours it takes to reach the launch pad. It’s a dream job for people who love being stuck in traffic.

Vehicle Assembly Bldg and Launch Complex 39

This photo (right) shows the Vehicle Assembly Building and Launch Complex 39 (click image for a larger photo). Could they have found a swampier piece of ground to build a Space Center? Doubt it.

I’ve been to Kennedy Space Center and I’ve stood beside the crawler-transporter, and it’s an impressive machine. It was built to haul Saturn 1B and Saturn 5 rockets to the launch pad. Each track on a crawler-transporter is taller than a man. There are eight tracks and each track has 57 shoes. Each shoe weighs 2,200 pounds.

At left: a crawler-transporter, which carries the Mobile Launcher Platform, which carries the Space Shuttle. (Click image for a larger photo.)

The crawler has 16 traction motors, powered by four 1,000 kW generators driven by two 2,750 horsepower diesel engines. Two 750 kW generators driven by two 1,065 horsepower engines are used for jacking, steering, lighting, and ventilating. Two 150 kW generators power the Mobile Launcher Platform. The crawler burns 125 U.S. gallons of diesel per mile.

We’ve spent billions of dollars to build up all this infrastructure; we’ve lost too many lives learning how to fly shuttles. And now what? We toss it away? We rely on other countries to get our astronauts to space?

Okay, whatever. We have to do what we have to do. But as someone once said, it’s a hell of a way to run a railroad.
