Headed Out.....

It's 78 degrees, the sun is shining, and I'm wearing one of my Celica Supra T-shirts.

I just cleaned the windows, and she's idling in the driveway to warm up a bit.

Time to hit the road, shake out any rain water still in her, and blow some cobwebs out of the brain.

Just got back with all the carbon blown out of the engine, and all the cobwebs blown out of the head.

Put about 60 miles on the car, and found it it has a water leak, probably the sunroof, that got the passenger seat and all the junk I had sitting on it, pretty wet.

SO.....I'll be leaving the windows down during the day for the next few days.


And I'll put a tarp over it so the rain won't go where it's not supposed to!

"Edge of Space" It 'Aint!

Rant time.....

I just received my new QST magazine, and on the cover as the lead story is an article about "Amateur Radio At The Edge Of SPACE!".....

It's an article about a group of high-school Hams who send home brew instrument packages up ~120,000 feet using balloons, and recording the downlinked data.

This is great stuff, and I greatly admire the young men and women who are doing it.


BUT....for crying out loud, STOP calling it "The Edge of Space"!

It's NOT.

It's not even close!

The official definition of "Space", is an altitude ABOVE 100km, or about 62 miles, a bit more than 328,000 feet.

120,000 feet is a bit more than ONE-THIRD the required altitude to be in "space", and as such is pretty far from being "the edge" of anything meaningfully close to "space".

I remember not too long ago when the guy jumped out of the balloon sponsored by Red Bull, and they insisted on using this same "Edge of Space" nonsense.

I sure don't have the big brass ones it takes to do that, and I also greatly admire Felix Baumgartner for having the cajones to do it, but it wasn't, and never will be, "The Edge of Space".

Knock it off, people....you're just demeaning the people who really do go into space for your own cheap amusement....

50 Years Ago Today

The Apollo 1 fire occurred, taking three of our Astronauts on their final voyage.





Gus Grissom, Ed White, and Roger Chaffee  perished in the fire inside thier Apollo Command Module.

The cause of the fire was eventually traced to some chaffed/frayed wire that caused a spark, resulting in an extremely hot flash fire accelerated by the pure Oxygen used at the time in the Command Module.

In the race to beat the Russians to the Moon, compromises had been made in the design of the Command Module, including the use of a pure Oxygen atmosphere. At the time it was deemed too expensive, and more importantly, too heavy, to include the required Nitrogen system so the the atmosphere in the Command Module would be "air", and a much simpler pure Oxygen system was used.

The hatch on the side of the Command Module had also been designed to open inward, and had many bolts to secure it closed, making it very difficult to get into the  Command Module quickly from the outside.

And many materials used in the interior of the Command Module were later found to be extremely flammable in a pure Oxygen atmosphere.

Manufacturing carelessness also played a factor in the accident, as quality controls were not up to the standards used today. One of the things that NASA did with the remaining Command Modules in the inventory was to put them on shake tables, and shake the living daylights out them to see if anything was loose. One thing I remember from from my NASA Soldering Certification classes was that several POUNDS of loose solder bits and loose solder "balls" were shaken loose from the Command Modules that were tested.

Every one of these little things was a potential short circuit that would be floating around in the microgravity experienced by the Command Module during it's flight, and the Engineers were horrified to see how much junk came out after the shake tests.

Wiring was also rerouted, tied down, and encapsulated with tubing at any point where it rub against anything to ensure that the insulation would remain intact.

And the pure Oxygen system was replaced with a system that used a 60/40 mix of Nitrogen and Oxygen until the Command Module was in orbit, at which time the Nitrogen was slowly purged, and the atmosphere replaced with pure Oxygen.

Manned spaceflight is an extremely risky business, even when practicing on the ground, and you will lose flight crews. You take every precaution you can, design things with triple redundancy, have detailed checklists that must be rigorously followed, and still, you cross your fingers and say a little prayer when the crew boards the spacecraft.

Man is a curious, exploring animal, driven in his quest by a thirst for knowledge and understanding.

And brave men like these lead the way.

God speed, Apollo 1 crew.

What A Difference A Day (or two...) Makes

Don't worry, I won't 'entertain' you by singing.

"Lake Long Beach" has sunk back into the Earth, leaving only very minor inconveniences behind.

The wind had knocked the vent stack for the water heater loose, so I had to get the ladder out of the garage, climb yp there, and put it back together. Our across the street plumber friend had knocked the mountings around when he installed our new water heater last summer, and it was just a matter of time before Mother Nature moved it around some more.

This resulted in two things happening. First, when the wind blew, the open end of the stack resonated like a large organ pipe with a rather disturbing thrumming sound, and second, when the gas burner fired up, it sounded somewhat akin to an F-4 Phantom lighting up in the driveway.

The blowing wind sound really bugged my wife, and the jet engine noise bugged her even more, to the point where she stated saying "Oh My God....IT'S GOING TO EXPLODE!".

So up I went to rectify the damage.

And we really ducked a bullet as far as water incursion goes. I had two boxes of "stuff" that got wet. One has a large, heavy Rohn "Non Penetrating Roof Mount" antenna base that was surplus from my wireless service provider days, and the other had some cleaning/waxing supplies in it.

The Rohn box had maybe 1/2" of "water damage" to it, and got securely taped up today, and the other box went into the recycle bin after I moved the items in it to another box.



And the grass is going to grow like crazy over the next few weeks!

Welcome to "Lake Long Beach"!

Just a bit of water in the back yard....



Even though we make sure the dog always has a bowl of fresh water in the backyard, I don't think she needs it today, and wouldn't want to wade out there to get to it...



The brick border is actually TWO bricks high....




If you know how big a DogLoo is, this will give you an idea how deep the water on the patio is...



Or if you don't know how big a DogLoo is, here's a standard size cooler-on-wheels...




View from the porch steps...



Nope, not doing any laundry today...

More Rain On The Way ***UPDATE***

Supposed to start again tonight, and then "Heavy Rain" all day Sunday, Sunday night, and "80%" through Monday night, tapering off through Tuesday.

With the ground as saturated as it is, I predict the return of "Lake Long Beach" in the back yard.

My wife told me there were whitecaps on the water in the L.A. River on her way home from work yesterday.......


Well, the rain started again early this morning, around 0300 when I had to get up and let the dog out.

Something about a cold nose in the arm or face just makes me open my eyes to see what's up.

It was off and on until around 0800 when it started coming down steadily, and it's been doing that for the last 6 hours.

So far we've received slightly over 1.25", and it's coming down at about .6" per hour.

And it's expected to continue like this the rest of the day, and through tonight.

And tomorrow, and tomorrow night, tapering off on Tuesday.

"Lake Long Beach" has returned, and might get into the garage if this keeps up......

Now that President Trump (God, that feels good to write!) and the adults are back in charge, "Hope and Change Cartoons" won't be published as much.

It was a great run, Mr. Jarlsberg. Thanks for doing it!

And in other news, we got TWO INCHES of rain last night. The back yard is now a lake....

See Through Engine - 4K Slow Motion Visible Combustion

Ran across this on YouTube while looking for something else.

It's really cool to watch the flame propagation from the ignition point through the chamber.

Anybody Ever Leave Las Vegas Headed NORTH On A Sunday??

I know you sure don't want to head out SOUTH, back to L.A. on a Sunday!

The reason I'm asking is that registration for "Supras in Vegas 2017" just opened, and I went ahead and registered.

Since God willin' and the crick don't rise we'll be living in Fort Collins at that time, I'm planning my route from Fort Collins to Vegas.

Since it's 803 miles, I'm not going to do it in one shot! If I were 20 years younger, maybe, but driving through that terrain, at night, alone, is NOT something I relish doing anymore.

So far, I'm planning on overnighting in Green River, Utah, which is almost exactly half way between Fort Collins and Vegas.

I'll leave Fort Collins on Tuesday, and then roll into Vegas on Wednesday. The event starts Thursday, so I'll have Wednesday night to get a good night's sleep.

The event ends Saturday around 1700, and then we always have a "Mark II get together dinner" at one of the hotel/casinos about halfway back to the Excalibur from the Las Vegas Motor Speedway.

I'll roll out of Vegas Sunday, stop again in Green River, and should get back to Fort Collins on Monday.

Hopefully the traffic headed NORTH out of Vegas won't be nearly as bad as that insane crawl back to L.A. would be on a Sunday afternoon.

I'll have to ask some of the regulars to the event if they've ever gone North on a Sunday.....
