Some Random Things

Cleaning up the site a little.  Finally moved the Chessboard Puzzle to the Secret Puzzle Page.  Including the Puzzle for Charity, there are now six unsolved puzzles here and a seventh is on the way when the 1970's TV project is completed.  I am toying with the idea of putting up some hints.   I really have no way of impartially gauging the difficulty of the Secret Puzzle Page puzzles, but I can say they are all much easier than the Puzzle for Charity. Let me know what you think.

Speaking of the TV Project, the main woodworking has been completed.  The "cabinet" is make of scrap oak plyboard and the "legs" are made from oak buttons left over from bookcases Agmorion and I made.  I may be able to do the wiring tomorrow, and the mounting of the pieces on Thursday.  We will see.  Hurricane comin', you know...

I am enjoying the Kindle and downloaded a huge number (like, eight) of novels like The Iliad and War and Peace and some other fancy stuff I tell myself I will probably read someday. 

I did read Artemis Fowl: The Atlantis Complex, though.  Other than "tedious" the only other word I have for it is "pointless", but you would have to read it to see why (don't do it).  Also read an Argyle Sweater book.  Some gems, not that great.  Do not get books like this for the Kindle - the resolution and contrast of the e-ink makes it difficult to enjoy the small details that sometimes make the joke.

Currently reading Think of a Number by David Baldacci.  I am three-quarters through and I am really happy I downloaded this one.  Fantastic.  Can't say too much, cuz I am reading it to Mrs. Snowurchin.  (Just something we do.  Shut up.) and we are only on chapter 7...

More later.

1970's TV Project

Jimmydunes had a Meizu miniplayer that was no longer functional and he asked if I wanted it for parts or whatnot. After it had been sitting in storage for about a year he tried to fire it up only to discover the unit would not take a charge. Most likely a battery issue.

After a little research showed that getting a replacement battery seemed to be at the very least a shipping and handling hassle and at the very most an expensive shipping and handling hassle he decided he wasn't going to get it replaced. Besides, as nice as the Meizu is as an all-around media player jimmydunes has plenty of other ways to watch/listen to/read the various media in his collection. Unless a free Li-ion battery in that particular form factor just poofed into existence, fixing it really doesn't solve any problems.

I agreed to take the player off his hands because I didn't have any projects going on since I had finished the chessboard. I thought it would be fun to turn the player into a somewhat-scale model of a late 1970's TV. You know the kind – big, bulky, made of wood, unreliable, usually had a smaller, functional TV perched on top of it after it died...

A major plus is that I could probably do this project without spending any cash. See, it's kind of hard to justify going through the process of filling out the paperwork to request funding from Mrs. Snowurchin for this type of job because I can never figure out what to put in the “But, for the love of God, why?” blank on the form... :)

First, I needed to check that the battery was the only problem. After removing it I measured 0.00V across the terminals - somewhat less than the 3 to 5 volts I was expecting. Hmm. I soldered some temporary wires to where the battery was formerly connected and fired up my 5-volt power supply.

It worked. Sweet. But there is no audio, because the speaker is an integral part of the case, and the back of the case needs to be removed to route the power (and several other) wires later. Now what? Well, I toyed with the idea of using the speaker from a partially dismantled Furby I had laying around (shut up) but I didn't have an appropriate way of driving it. Since I didn't want to turn this potentially fun woodworking project into a PITA electronics chore, I decided to just make use of the output jack instead... well, the connectors, anyway.

Using the jack itself would force me to make the TV much wider than I wanted to so I routed wires directly from the internal tabs instead. A short MP3 test with some temporarily soldered wires and some useless (to apparently-malshaped-earhole-me, anyway) iPod earbuds showed that it should work just fine.

I likewise bypassed the on/off switch with some wire and an old calculator key switch – no problems there. All the temporary test wires are intended to be removed to allow me to fit and re-fit the player into the wooden TV case as the project progresses without stressing the solder joints and what have you.

But all of this doesn't mean too much if the battery problem isn't solved. It turns out I had a cheap battery-powered screwdriver I could scavenge for the Ni-Cd pack inside. I charged it up a bit and tested it out, a little dubious that it would work. It did. Nice.

Fair to say at this point I have violated the warranty on the media player.

Chessboard Project: Completed

Wow. It's been a while since I have written anything. Usual excuses apply, of course, plus I really didn't have anything of substance to say. “Oh, yeah, like this blog is usually packed to the rafters with the most trenchant insights ever to grace the Internet,” you say. “You're eloquently mean,” I sob.

Anyway, I finished the chessboard project. All the wood was 100% recovered from past projects or otherwise free. The stains and gloss sealant were likewise potential garage-fire-accomplices I was happy to get rid of.

The finished product is 20” x 20”, and it took me about 6 hours to put together. Lots of sanding. Lots and lots of sanding. Nothing too much else to say that the pictures don't, but here are my “lessons learned”:

  • Dollar Store sandpaper is absolutely useless. I don't mean that in a fit of elitist monocle-and-tophat wearing snobbery - it actually disintegrates within seconds of turning on the sander. Go with 3M-made stuff instead.
  • Sixty-year-old maple (recovered from a throwaway table found on the roadside) and fairly new cheap cedar boards (leftover from the Windsor II Playset project) turn roughly the same color when hit with a coat of stain. That was pretty unexpected – I kind of figured on a very sharp contrast with little effort on my part. What I ended up with was fine for a generic woodworking project but completely unacceptable to actually play chess on (see top left pic).
  • Related to this, I was happy to discover that my hands are steady enough to re-stain the dark squares in place without killing the project. Buoyed by this success, I cockily stained the trim pieces darker as well. Go, me.
  • Moths like shiny things, so I should really remember to shut the garage door if I am gloss-sealing something. I was able to mostly dig the partially fossilized morons out of the surface of the board, but I guess the project is technically something like 99.99% vegetable, 0.01% animal, now...
  • I cannot wait until I can replace my Craftsman scroll saw with something that doesn't completely suck. I would also like to replace my Craftsman router with something that doesn't completely suck. Oh, they make great hand tools, but my experience has been that the design engineers and marketing folks that greenlighted those shoddy electrified contraptions should be forced to use them for an hour or until something breaks or someone gets seriously injured – whichever comes last.
One last thing: I added a Secret Puzzle to the bottom of this. Since I doubt that anyone (other than my 2-year-old) is going to overturn the chessboard to see what is underneath, I present it here. I will post it on the Secret Puzzle page later. FWIW, I know that the dark squares are actually cedar – I wrote the puzzle before I finished the board. Good Luck!

Site Update, New Puzzle Hint

Sorry no posts recently. My excuses:

My wife bought me a Kindle DX recently and I have been putting it through its paces. It does exactly what I want (act like a book, and don't be a computer) 100% perfectly. My Pros: Holds 3,500 books, reads PDFs, I don't need to provide near-constant life support to it as I would have to do with a computer (updates, drivers, patches, virus definitions, etc.). My Cons: interface is as clunky as a late 1990's smartphone, can't sort by price on the Amazon Kindle site via the Kindle (Most pre-1923 books are free, see, so it would be nice to see the free ones like you can on the regular Amazon site.)

Related to this, since I have the Army Cryptography Manual PDF on the e-reader and it got me thining on this bent again, is the Khan's Cons puzzle on puzzlemonster.com. I have allowed myself to get wrapped around the axle once more with this thing. Yes, I am stuck... still. Apparently, I don't know the meaning of the word “quit”. Unfortunately I am extremely well-acquainted with the phrase “virtually pointless obsession”. If I could just nail down one single letter with 100% confidence... Sigh. I hereby passive-aggressively present the next hint to the Puzzle for Charity:

Hint #3 (Posted 2130 081610): The first letter is “W”.

Speaking of “virtually pointless obsessions”, I started a new woodworking project! I am building a chessboard out of scrap wood in the garage. The light squares will be maple (the last bits from a table rescued from the side of the road) and the dark squares and trim will be cedar (left over from the Windsor II Playhouse project.

But what about Captain Awesome?! Yep, more episodes are coming soon.

Stay tuned.

Oh, Yeah? Parse This!

Wait... is that "adjective-noun" or "adverb-verb"? No time for that now, I just hit something...

DIY Landcruiser Third Brake Light Fix: $0.69

Today I helped a friend repair a malfunctioning third brake light on his 1996 Landcruiser FZJ80. He was alerted to the problem by the local police and his inspection is due this month so there was really no choice but to take care of it.


Searching around for a replacement, he discovered a new part was going to cost a whopping $200! Since there was nothing to lose and everything to gain by attempting a repair, we decided to give it a shot.

After using a voltmeter to verify power was getting the the board when the brake was depressed, we dismantled the brake unit (picture at upper left) and we saw that there was really nothing to it: a string of 76 low-cost red LEDs, a low-cost resistors, and a low-cost 5.1 volt zener diode. The point I am belaboring here is that $200 seems kind of steep for less than $10 worth of electronics and a plastic shell...

There was no obvious physical damage to the board, and nothing looked fried, although in retrospect the zener maybe had carbon residue on its leads (a sign that it burned up at some point). The voltmeter told us no juice was getting past the diode. Sure enough, temporarily shorting across it caused all the LEDs to light up. Looks like we found the problem.

NOTE: You may ask “Isn't shorting across things bad?” Answer: “Yes. Yes it is.” Don't do it unless you know what you are doing. Parts are there for a reason – you have been warned. In this case, the zener is probably there to act as a voltage suppressor to prevent power spikes from killing the red LEDs.

You may also ask “How do you know it was a zener diode?” Well, it was labeled it had the typical markings and form factor of a though-hole diode and was labeled E51. An Internet search narrowed down the choices to 5.1V zeners after that.

A quick drive to Radio Shack... Well, not so quick because traffic was ridiculous, and there were actually two Radio Shacks involved because the first stopped stocking “things that are useful” to make more room for “tasteless, shoddy, and ill-conceived stocking stuffers”. Ok... ok.... I am being unfair, but the love-child of Michael Bolton and Carrot Top that was working at the first one really pi... Ok... ok... calm down...

Anyway, the second Radio Shack had some low-current 5.1V zeners. They are $1.39 for a pack of 2. Feel free to get on their site and read the five unreasonably glowing reviews of these extremely standard parts. FWIW, the site also alleges they come with a hilarious 90-day parts and labor warranty for some reason.

We got back and soldered in the new one, making sure to get the polarity right (that is, stripe to the left – see pic).

These 1N4733A diodes are NOT an exact match to the original, and do not have a very high current capacity so I was kind of expecting the replacement to blow right away after we plugged it back in. It held just fine. We kept the brake pressed for five minutes straight and saw there were no problems. The diode was running hot, but not alarmingly so. We then pumped the brakes 10 times in succession to see if it would hold up under that kind of stress. Again, no problem.

The immediate problem of the upcoming state inspection appears to be solved. Of course, the real test will be how it handles real-world conditions: driving all day, sitting in the sun for long periods, and whatnot. I figure if it survives the week, it might survive a year or longer.

Just in case, I will go through my stock of electronics parts and see if I can't find a better match if it decides to die sooner than later.  And who knows... maybe I can take advantage of that parts and labor warranty after all.

The Omnicron Imperative (Part VIII)

(Looking for the other parts?  Check the sidebar.)

The seven men and four women of Team Constant Lightning sat around the U-shaped conference table studying their assignments.  They all had worked together on one mission or another over the years, and silently nodded at each other in recognition.  Each was the best in his or her fields - they all knew that.  There was no room for false modesty in this business.

Stanley "Twitchy" Twikowski scuttled around the table passing out what were known internally as 'goodie bags'.  He cursed under his breath each time his oversized black leather duster snagged clumsily on the wheels of the small aluminum cart he was pushing.

"Don't open them until I say so!" he squeaked asthmatically.  The team members that were prematurely releasing the clasps on their bookbag-sized leather sachets stopped what they were doing and rolled their eyes at each other.  Twitchy might be a technology savant with an IQ over 200 but he also had a Napoleon complex sized to match.

After the last bag was distributed the lights dimmed and a three-dimensional representation of the Earth hovered above the gap in the tables bathing everyone in a warm greenish-blue glow.  The three-foot sphere, generated by laser projectors around the room, rotated slowly in a mist of microscopic water droplets sprayed from above and below.

Superimposed on the hologram were thousands of multicolored spots - most were green but some yellow and red could be made out.  Some lights winked on, while others faded away.  Dashed lines connected some and then were washed away or reconnected elsewhere in what looked like a random fashion.

"Our Heuristic Electronic Real-Time Observer, or HERO, mainframe has been hard at work since we received the Omnicron image from the field. " Twitchy removed his glasses and wiped them on his Cheetos-stained t-shirt.  "For those of you that don't know, what you see here is all of the global Internet, cell phone, CB radio, and land line communications over the past two years filtered through our Omnicron database.  HERO finished crunching through all of the data a few hours ago so let's fast forward to the results instead of watching the pretty lights go blinkity blink, shall we?"

The dots and lines became a blur and suddenly converged into six red pulsating target symbols.  Three were in America - one in Southern California near the Mexican Border, one in Rhode Island, and one in Western New York State.  The other three appeared to be on the outskirts of London, Kabul, and Berlin respectively.

"You may now open your mission toolkits.  You will notice they are mostly the same old stuff geared toward your particular fields of expertise, but we have modified them a little based on the nuggets HERO was able to glean from the electronic noise." He sounded like a proud papa showing off pictures of his new baby. "Time is very short.  I only have time to go over the changes once so pay attention."  He pushed a greasy red shock of hair out of his eyes and held up what looked like a silver Tylenol capsule.

"This," he announced, "is how you will keep in contact with your partner and with HQ during the course of this mission."  The team members looked doubtfully at the pill.  "It may not look like much, but it is actually a self-contained encrypted satellite uplink-downlink system.  After it is swallowed the outer casing begins to dissolve, turning that chemical energy into electrical energy to power the device.  Your intestinal track then acts as a waveguide, much like the speaker design in a Bose radio, to transport sound either to the device or to your ears.  It will remain functional for as long as it is in your digestive track."

"The second item is a biological suppressant," he announced, holding up another pill - this one unpleasantly brown-colored. "It will allow you to forgo food and sleep for the next 36 hours.  In addition, it will eliminate the need for excretory functions such as sweating or calls of nature.  Finally, an enhanced dopamine re-uptake inhibitor infused into the capsule will allow you to focus longer, with the side effect that certain drugs will only have a minor affect on your brain's chemistry.  Please swallow both pills now."

The gold team did so.  Twitchy continued with his mission overview.

"As you can see HERO has picked out six likely locations for Omnicron activity.  You will notice that the bungled robbery of the gas station in the middle of nowhere that alerted us to the continued existence of Omnicron is not on this display.   Investigation by local authorities seems to confirm that the perpetrators were interested in nothing more than the contents of the cash register.  A bit of serendipity that someone one our side was there to stop them and that the computer was able to link that cell to the highlighted target in Afghanistan.

"Each of you has been paired with another Constant Lightning teammate with whom you are now electronically linked.  You may now proceed to your targets assigned to you in your mission packages and highlighted on the display.  Any questions?"

"Hey, genius, I might not be the math whiz you are but even I can tell you that two times six is twelve." Juan Sanchez interjected, cleaning his fingernails with a hand-beaten copper dagger.  "I'm only counting eleven of us, so, unless you plan on growing a pair and joining us for some real action for once, it looks like we're a man short."

Twitchy's face turned crimson and he balled his fists at his side with indignation.  But before he could sputter out an acid-filled response a shadow detached itself from the rough-hewn rock wall and strode into the light.  "Well, then, Mr. Sanchez, maybe Santa should bring you an abacus for Christmas."

For a moment, the only sound that could be heard was the distant rumbling of the mine shaft elevator transporting another group of Red Team members to the surface.  The room then erupted into shouts of joy.  High fives, fist bumps, and not a few hugs were passed around.  Even with the biological suppressant pills in place the female members of the Gold Team were having a hard time fighting the urge to swoon.

Captain Wonderful Q. Awesome was back.

The Omnicron Imperative (Part VII)

(Looking for the other parts?  Check the sidebar.)

Omnicron.  The name, taken from the Greek words for "all" and "time", implies their mission statement - to rule forever.

In 1939, Adolf Hitler himself commissioned the secret Omnicron Project, which researched the possibilities of group mind control.  Rumor has it that their logo was partially inspired by the movie The Wizard of Oz.  After seeing the 'poppy field' scene of the film, Hitler became intrigued with the possibility of using clouds of narcotics to subdue the the otherwise resistive masses of his soon-to-be conquered territories.

Although the Omnicron Project enjoyed some minor successes the flow of the war could not be stopped. Armed with several railroad cars packed with Nazi gold and the best bio-scientists Germany and its allies had to offer, the project moved underground.  It expanded quickly during its first few years primarily by coercion and kidnapping key talent when needed. This extremely well-funded organization grew from a small handful of zealots to an influential shadowy hand capable of nudging governments around like a grandmaster moving so many chess pieces. 

For nearly four decades after World War II, there was virtually no troublespot on the globe where Omnicron's fingerprints wouldn't be found.  Although group mind control remained their ultimate objective they branched out, somewhat successfully, into other nefarious regimes.  Eventually, Omnicron agents could be found in the inner circles of the highest commercial and government offices everywhere.

In 1983, a suspicious string of nuclear reactor failures in New Jersey, Russia, Argentina, and Germany alerted U.S. Intelligence to the existence of Omnicron's worldwide counterfeit fissile materials ring. Team Alpha Ninja Omega Niner was called in to hunt those responsible for selling bogus fuel rods and shut them down once and for all. 

Thirty-six hours later, all that was left of Omnicron were hundreds of blood-splattered chalk outlines peppered around the globe and a hundred-meter wide crater in the floor of the Kalahari Desert.

Or so everyone thought.  The still image on the screen would seem to indicate that they were back, somehow.

"Each of you has a mission dossier with your name on it under your seat.  Please take a moment to retrieve it," said the General from the stage as he shut off the overhead projector and closed the flag curtain. The team members began to rummage under the theater-style seating for their packages.  "You will notice that some of you have gold envelopes and some of you have red envelopes."

The ANON team glanced around.  Very few gold islands stood out sharply in a sea of red. 

"Those of you with gold envelopes are the primary response team now known as Team Constant Lightning.  Those who have red envelopes will be known as Team Eternal Thunder and will provide support to the gold team.  You may break the seals on your dossiers now and follow the instructions you see there.  Good luck and God bless America.

As was custom with every mission meeting, it was ended with the playing of the Star Spangled Banner on a continuous loop.  Each Alpha Ninja Omega Niner team member filed past the General and the fifty-foot flag, snapped off a salute to both, and left for the destinations described in their mission assignments.

Many would be returning to this room wiser and more battle-hardened then ever.  A few would never come back.  They would prove to be the greatest heroes of them all.

The Omnicron Imperative (Part VI)

(Continued from Part V)

General Steel cleared his throat.  "Excellent job, ladies and gentlemen.  Very thorough.  The contingent that pulled off this assassination was able to disappear without a trace, as usual, but I am not telling you anything you don't already know since many of you were there."

Most of the ANON team in attendance smiled at each other and nodded smugly.

"But, obviously, a dead man lying in the middle of the plaza in broad daylight is going to draw unwanted attention however you slice it," the General continued.

"Our Black Ops division was able to suggest the bistro waiter as a 'person of interest' to the local police and the media.  The Black Ops folks also provided 'witnesses' and the original ATM surveillance footage to both groups, clearly showing that he was the last person to have contact with the target.  We received word a few hours ago that he had been arrested and interrogations are underway.  The newspaper and TV folks have begun their expertly guided vilification process - within a week he will have been tried and found guilty in the court of public opinion. 

"Our hands are clean."

"With Fantagucci eliminated, his worldwide weapons and slave trade ground to a halt literally overnight and, without his leadership, the organization has simply melted away.  We won't be having any more trouble from them.  Any questions?"

Juan Sanchez, demolitions expert and champion knife fighter, stood and shouted to make himself heard from twenty rows back. "Sir, with all due respect we could have been given this information via routine encrypted satellite channels. You mentioned something about the 'real' reason we were here?"

The General's always businesslike demeanor became even more stony as he locked eyes with Sanchez.  "So I did," he said, "So I did...  But if I had held this meeting remotely we all wouldn't have been treated to a dose of your trademark Honduran impetuousness and flip remarks, now, would we?" Some in the crowd tittered and Juan returned to his seat, chastised.

With a click of the remote control the paused image of the dead man in Milan was replaced with a photograph of a flower wrapped around a swastika.

Several dozen team members gasped at, what was to them, an all too familiar image, but many of the newer recruits merely murmured and glanced around.  They had no way of comprehending the deadly significance of what they were seeing.

"The Omnicron threat is back," General Steel announced gravely.

Leave Us Alone

Sir or Ma'am:

We are very concerned over what appears to be an irrational fascination with us on your part.  Frankly, we have no illusions about being able to pursue private lives - after all, that is the price of fame - but your ridiculous obsession is causing us to fear for our very safety.

You bother us using the most intrusive means at your disposal to satisfy your curiosity, and then brag about your exploits to a world that barely cares.

When we think of the time, money, and resources that you could have spent chasing down a cure for cancer, feeding the homeless, or just donating to charity instead of this nonsense, it makes us sick.  Hell, even taking that cash and setting fire to it in a parking lot somewhere would have been better because it would have, albeit briefly, provided light, warmth, and entertainment to lookers-on.

You pry and pry and justify your shenanigans by calling it "searching for the truth" or "solving a mystery" or something equally trite. 

Here is a secret for you: we have no more secrets. 

We ran out of those long ago, and you know it. Now you are just using us to justify your existence and practice your bizarre and practically useless "craft". No matter how much you probe, prod, scan, sample, photograph, or x-ray us, in no way, shape, or form will the cost and effort involved justify the scraps of data that you allege to obtain from your efforts.

And then you have the gall to shout your "findings" to the world, promising even more startling revelations if only if some far-sighted person would throw you some more cash.  Unbelievable.

Just leave us alone. We mean it.

Very sincerely,
