Electricity, EEEEEEEEEEEEEE-lectricity

Hehe, remember that one?:

During my recent plumbing project, I considered that connecting pipes, if done wrong, at least wouldn’t kill me.  Still, I found the process irritating, and after the pain of cinching down threaded pipe connections took its toll on my elbows, I concluded that I would much rather be doing electrical work.  Besides which, if I wear leather gloves, the shock of 120 volts is reduced to a mere tingle even if I screw up the breaker.

Still, despite this mitigated lethality, when I find something done wrong, I grow concerned.  So it was that I decided to tackle the unattached electrical outlet in the garage.  I really should remember to take before pictures, but I didn’t this time, so I’ll have to explain the setup.

First, I’ll mention that it was a 2-pronged ungrounded outlet.  That was part of the problem, as an obviously bad choice for the garage, which would presumably be more likely to power higher-amperage devices.  More troubling was that the outlet wasn’t bolted into the wall box, and the wall box itself wasn’t even attached to either the adjacent stud nor the drywall.  In short, there was an electrical line leading into a loose box, then wired into an ungrounded and unattached outlet–a hole in the wall with exposed hot wires.  What could possibly go wrong?

My main concern was that the kid might poke a finger in there, so I had taped up the cover.  And as the outlet lacked a ground, as mentioned, it was of limited use anyway.  But then, as I was shoving rolls of carpet into the attic one day, I considered: how hard would it be to run a separate ground to that outlet and make it serviceable again?  The basement has a ground line running through the joists, so perhaps the attic had one too.  I searched around, but no ground wire was to be found.  That seemed odd, seeing as this was the only outlet in the house which didn’t have a ground.  For a moment, I panicked, thinking that none of the outlets were grounded, but these fears were quieted when I opened a junction box and discovered that all the wiring was modern Romex with connected grounds.

I followed the wire from the box to the obvious spot where it dropped down and fed the outlet in question.  This wire, too, was grounded, which begged the question: Why wasn’t the outlet grounded?  And where was the ground wire?

Climbing down, I checked the outlet box again.  Turns out that the wire did indeed have a ground, but it had been clipped off at the point where the outer insulation had been stripped to separate the wires.  So someone had deliberately installed an ungrounded outlet on a grounded line, and had removed the ground.  Why?  Tugging on the line, I discovered there was no extra wire, so I couldn’t simply connect the ground to a new outlet as-is.  And of course, the box wasn’t mounted so I’d need one that would.  Sigh.

My motivation to complete this project coincided with Liz re-painting the living room.  With my entertainment center out of action, and the threat of being drawn into a painting project looming, I concluded that this electrical problem needed an immediate resolution.  Off to Lowe’s!

In the electrical isle, I wondered why both metal and plastic boxes were the norm.  Why would one be used over the other?  Maybe metal was for industrial buildings.  But for me, I rather preferred to use non-conductive material to house electrical wires.  I also bought a roll of 14 AWG wire to extend the ground.

Back at home, I followed the usual procedure of sequentially flipping breakers until the correct (and least logical) circuit was found.  Then I got to work removing the unmounted box, which wouldn’t fit through the outlet’s hole in the drywall.  I wonder how it got in there to begin with.  Was it installed before the drywall, but never mounted?  The prior owner had done some weird electrical projects in the basement, none of which inspire much confidence, so this could very well be one of them.

At least it was the garage, and the drywall isn’t painted out there, so I didn’t feel much hesitation in sawing through it.  I removed the useless metal box and installed the plastic one, having poked the wires through and extended the ground.  The outlets in this house are worn out, so I’ve been replacing them as demand necessitates.  This is the 5th such outlet to need replacing, so I have a supply of them on hand.

I patched the hole with leftover drywall and spackle.  It doesn’t look very clean, but it works and is far safer than the prior potential disaster.

What the hell was wrong with this guy?  You’d think that electrical work is something worth doing right the first time.

Fortunately, my project was finished quick enough that I was able to help out with the painting after all…lucky me.

Standards (Part 2)

So in Part 1, I chronicled my woes regarding a seemingly simple task: connecting a garden hose to an unused water softener spigot in the basement.  In short, it was not as easy as I had thought, and I had resorted to an unconventional solution.  Unfortunately, that unconventional solution did not withstand the test of time, and when I used the hose later, the sealant popped loudly and water sprayed the wall.  The pressure was just too great.

Curious as to how much pressure was in these lines, I researched what standard pressure should be.  The answer: 40-60 psi, no more than 75.  This only served to cause more questions though, like how deep does water have to be to reach that pressure?  Hmm, back to the Internet.

The answer to this question: about 30-40 meters.  That’s…pretty deep.  I certainly wouldn’t ever want to be that deep under water.  And that’s residential pressure, after the reducer.  It’s no wonder broken fire hydrants turn into geysers, and why water towers are so creepily tall.

But back to the job at hand.  I was determined to get this project to work, so I decided on another tactic that I had toyed with at the time: splitting the washer hookup and connecting a hose directly to that.

This spigot has certainly seen better days

Once again, it was off to Lowe’s to stare at pipe fittings.  I admit–I rather enjoy just looking at components like this, formulating solutions in my mind, then allowing my attention to drift to potential future projects.  The trouble is, staring blankly at rows filled with utility infrastructure sends visual messages to those around, manifesting into thoughts such as: “This guy has no idea what he’s doing,” or “He’s going to break something or hurt himself,” or “Maybe I’ve watched too much 90s-style man-of-the-house-deprecating sitcoms and I’m judging him too harshly when I really don’t know what he’s capable of.”

I highly doubt that it’s ever that latter thought, however, so in general I try not to tarry too long.  Fortunately, my years of work experience have taught me a useful skill: how to look busy when I’m not, and how to look like I know what I’m doing.  I must have pulled it off, because no one approached me.  And besides which, figuring things out is part of the fun of a project.  I don’t want a detailed walkthrough for everything I do in life.

Anyway, I quickly found a copper hose splitter.  But–would this fit the laundry hookup?  I presumed it would, but I also presumed I would find something to fit the water softener spigot, thinking everything in plumbing was standardized and easy to figure out.  Also, the laundry hose stays pressurized, and since I didn’t want to leave a garden hose pressurized constantly, I would need to split the hookup, and then install a value on the hookup I would use for the hose.

Then it occurred to me: I would buy another wash machine line, which is designed to stay pressurized, then terminate it in a valve, then attach the garden hose to the valve.  Plus, having a washer hose in my possession at the store would allow me to determine if the splitter would fit.  So, I wandered over to the appliances, found a set of hoses, opened the box, and attached the splitter.  I was gambling, of course, that the existing hookup and hose were the same size, but since I couldn’t find any size other than 3/4 in the entire store, I took that to be reasonable confirmation that it was a standard.

The next objective: attach the utility hose to a ball-valve.  All the valves were female-threaded, so I had to find a male connector.  Fortunately, that was easy through trial and error, though I later found out that hose threats and pipe threads are different, but a male 3/4 pipe thread will still attach to a 3/4 female hose thread (though not the other way around).  And fortunately, the Internet was pretty unanimous in that doing this, while not the way things were designed, wouldn’t cause any problems.  So, I didn’t bother swapping this out for another 3/4 male pipe to hose thread adapter–which is what I attached to the other side of the valve for the garden hose.  For whatever reason, it didn’t occur to me that utility hoses had hose thread–something new to learn I guess.

The difference is that hoses use pressure to seal against a rubber gasket, because they’re also designed to be removed if desired, whilst pipe thread is meant to be cranked down and left sealed eternally (bypassing the need for a washer), and is so threaded finer to reduce gaps.  For those who weren’t aware of or considered this distinction, myself included, there’s a brief explanation.

Having all the parts (splitter, utility hose, male thread connector, ball-valve, male thread connector to garden hose), I set off for home.

I never did use those hose clamps–they were too big

The splitter attached easily enough, followed by the existing utility hose, then the new one.

After doing this, I asked Liz how old that hose was, which we determined to be the one that came with the house, so it’s probably due to be replaced before it catastrophically explodes

Then it was the fun part: assembling the copper parts.  I really wonder how plumbers do this, because I applied the tape and cranked those bastards down until I ached all over, and they still leaked.  Eventually, after experimenting with additional Teflon layers, I got the leaks to stop…mostly.  The garden hose side still drips ever so slightly, but not enough to bother with taking it all back apart and adding more tape, and only when I leave it pressurized.

I let it sit for a time, ball-valve closed and the line under full pressure.  For whatever reason, I expected my handiwork to explode violently, embedding me with copper shrapnel.  But rationally, if anything were to fail, it would be that ancient rubber hose that’s been on the line since the 60s.

That silicon tape got a new use–it’s a much cleaner solution than duct tape, although eventually I might get the right sized hose clamps for a more permanent fixture

I feel much more confident with this setup, though my prolonged work back there with the piping shook my confidence with the existing pipework, like that old utility hose and the shutoff to the outside spigots that’s so rusted I can’t turn it.  Maybe next I’ll learn soldering.

A Lubbock County Almanac (January 11, 1995)

I’m home from school.

I just ate a snack.  It was cobler.  Leigh was holering and screaming because she wanted to cut her piece.  She hollered to mom that I cut her piece this long ‘           ‘ and this wide ‘                                ‘ when I really cut it this long ‘                                                        ‘ and this wide ‘                                      ‘.  Don’t ask me.

Se ya later!

This story begins with a little bit of mystery.

Well, initially I was just involved with another one of my web design projects.  I had previously built a dashboard of sorts–a web page that had embedded widgets.  I would open the page with my Raspberry Pi, and plug it into the TV.  Then I could just switch inputs and see the displayed info–weather and news–on my main TV.

The problem with this method is that I could never figure out a way to automatically open the browser upon boot and enter kiosk mode.  Usually this wasn’t a problem, but whenever the Pi got unplugged, I had to hunt down a mouse and keyboard so I could relaunch the browser.  The Pi’s browser also had a habit of timing out, so I’d have to refresh it manually, which again meant hunting down a mouse/keyboard.  Eventually, the novelty of the project wore off and the irritations outweighed the benefit, so I moved the Pi to the basement where it sits idle–serving only the purpose of being a low-risk device with which to practice remote shell Linux commands from the command line terminal.

Then I realized that since the Xbox has a native browser, perhaps I could revive the dashboard project to simply run on the Xbox.  I dug up the URL from where I had buried it, and launched the site.

The news feed wasn’t working, and the embedded calendar was redundant as I had a setup already running that in the basement.  So the dash would need a redesign after all.

I settled on 3 panes: my embedded NOAA radar, a weather forecast widget, and a news feed.  The first 2 I already had working, and some CSS got them positioned right.  But for the life of me, I could not find a reliable news feed that allowed iframe embedding.  The former method I had been using was a free Google service, which they had since deprecated.  Everyone wants you to sign up for things now.  Apparently something as minor as general news is no longer considered a free service.  Pity.  After failing to find a replacement, I abandoned the news feed idea.

I needed something else to fill the space, and I concluded that I would just complete the weather theme and find a free webcam.  I began with local news stations, but as with their Doppler radars and news feeds, nothing was intuitive, embeddable, or truly free.  Does everything have to be a source of revenue?  There was a time when the Internet was considered a free medium.

Further searches revealed a local webcam.  It was good resolution, too, and a genuine live-feed (something that rarely exists anymore).  Plus, the hosting server didn’t have any lockouts on iframe embedding.  Some more CSS and I had the webcam feed on my dashboard.

It could have ended there, but I grew curious.  Who would host a publicly-available webcam?  I began poking around the hosting domain.

The website’s design was pretty basic by modern standards–no HTML5, no adaptive content, no CSS styling.  It was a refreshing throwback to the Internet of the 90s.  The site itself was a resource on radio: HAM, scanners, AM PSA; and where to learn about them and buy equipment.  I tuned in to 1660 AM–the listed station, and heard a local broadcast of a High School sports event.

Further intrigued by this grass-roots site, I did a WHOIS search on the domain, and found to my surprise that the site’s registrant’s information wasn’t blocked.  The address of his office was public, and as it turned out, just a mile north of my house.  The webcam couldn’t have been much more local than that.

Something about the site inspired me.  Maybe it was guilt at having access to free information and a webcam, or a desire to give back.  Maybe I just wanted to see if I could help someone, or simply needed an excuse for another project.  Who knows?  Whatever the reason, I spent a couple evenings coding a new front page for the site.  I modernized it and organized the information so it was easier to navigate.  I assigned this redesign it’s own subdomain and hosted it on my server.  Then, I sent the owner an email.

I told him I liked the information on the site and the webcam, and offered the redesign code freely were he interested.  I told him that it was nice to see such a site, obviously self-hosted, and offering a public service.

The email was a Yahoo! domain, and as I was a random stranger reaching out from the internet, I didn’t expect to receive any response.  But to my surprise, hours later, he answered.

He explained in great detail the site’s content–the public radio station for citizens to make announcements and what he uses to transmit local high school games.  He confirmed the webcam is for public use, and that the local Channel 2 news uses it sometimes in their weather reports.  He explained that his maintenance of the business he’s mostly retired from, but keeps it running for extra revenue for his hobbies.  Consequently, he wasn’t interested in help with the web design, but he thanked me for offering.

I confess, I had always found HAM hobbyists to be weirdos, but this man was surprisingly normal, giving off a vibe of being an older man with hobbies that overlapped a personal business.  We should all be so lucky.

I thanked him for the information and told him this was an interesting experience as a segue into another world of communications technology for me.  It reminded me that while a technology inevitably becomes commercialized, and the large companies garner the most attention, niche groups and hobbyists remain, using the technology for its original purpose, free from the capitalistic motivations of shareholders.  It remains as evidence that intellectuals still pursue knowledge for knowledge’s sake, and offer free benefits to the population as a whole in the process.

Tori

Whippets: one of the goofiest breeds of dogs.  Their dopey intellect combined with their lanky builds, incredible speed, laziness, and absolute demand that they snuggle and not sleep on the floor–gives them such a darned endearing personality.  It’s so endearing, that rarely can you find a whippet owner who only has one.

So it was that we acquired Tori–the whippet addendum.  Liz thought that Faye needed a whippet sister, but in reality I think that was just a response to this universal need to collect them.  After extensive searching, she found a vet who breeds, shows, and rescues whippets.  One of these rescues, Tori, was so nervous and scared that she was ill-suited for showing.  She sat around the vet’s office for a time, until she was sold to us.

Always a mama’s dog

When we picked her up, Tori was wearing a green handkerchief.  She was terrified of the change, and especially afraid of men–a fear which never fully dissipated.  She took cookies from Liz but not me.  We bought her her own cage, but she refused to used it–preferring to accompany Faye.  She quickly adapted to nights on the bed, however, but bit me once in fear when I came to join late one night.

That’s the dopey whippet look

She never outgrew her wariness of people, but time made her less cautious, and while it was a rare moment to see her play like a dog should, she would still bark when she wanted something, give paw incessantly when she was feeling especially whippety, and took cookies from anyone who offered.  She was a regal whippet, and never reduced herself to fighting with the rabble.  When Faye overstepped her boundaries, Tori would either push her aside, or growl; and that was enough.  The rest of the time she spent sitting in her chair in the bedroom–her throne–far from the noise and chaos of the world.

One of the few men she took a liking to was my dad

Yet she had her less-endearing peculiarities.  I never figured out why she loved bread so much, but she would steal it out of the trash and off the counter, making a giant mess of crumbs in the process.  And she stole bones.  In fact, she had a predilection for systematically removing every item from the trash, irrespective of its classification as food, and arranging the debris on the carpet.  But ultimately, she found her niche in the family.

Like all whippets, she loved the sun

Then she started losing weight.  Until this point, she had had her share of medical problems.  She had tumors, arthritis, and nerve pain; but she was strong and rarely complained about her ailments, and until now she had fought through them.  But her weight loss accelerated, so upon the vet’s recommendation, we started feeding her soft dog chow.  She scarfed that stinky stuff down and it helped for a time, but a couple weeks ago, she stopped eating this too, and began showing more overt signs of digestive problems.

One of her last lucid moments, before she stopped responding

She leaked blood, stopped moving, and became completely emaciated within days.  Suspecting the worst, we made a vet trip.  The diagnosis pointed to a ruptured ulcer, and lacking practical treatment options, we proceeded with euthanasia.  With all the stoicism I could conjure, I watched as the vet injected Tori, and within seconds, she stopped breathing.  The receptionist handed us tissues.  My composure failed.

I spent the day digging her grave.  I buried her with a can of that stinky chow and some cookies.  Liz adorned the site with daffodil and crocus bulbs.

Bye, Tori

I want my dog back, but I’d rather she didn’t hurt anymore.  I hope she has the comfiest chair and stinkiest chow, wherever she is.  I miss you, Tori.
