The Gray-Hoverman antenna

I threw together a Gray-Hoverman antenna tonight. It’s literally two pieces of bent copper wire taped to a piece of plywood, connected with a 75 to 300 ohm transformer like this one, stashed behind the entertainment center. I’ll pretty it up at some point.

This $6 transformer is the most expensive part you need to build a quality antenna

I now get 15 channels of over-the-air TV. With my old antenna, I only got 10.

With some tinkering, Antennapoint suggests I should be able to get channels from as many as 9 nearby cities, including, potentially, Springfield IL, and Jefferson City, MO.

I’m definitely hoping to pull in a couple of additional distant PBS stations, since they tend to vary their programming a little bit more. It would be nice to get an additional PBS Kids station, since the local PBS Kids stopped carrying a couple of shows my oldest son liked.

A basic cable TV package only gives you 20 channels, and most of them are stuff you wouldn’t want to watch anyway. And they usually don’t include the extra DTV channels. For instance, the local PBS channel also broadcasts a channel that alternates between home improvement and cooking, a kids channel, and a news channel. All are better than their cable equivalents, and they’re free. A couple of the other stations broadcast syndicated programming on a secondary channel.

I eventually want to build a better one and possibly mount it in the attic or even outdoors. But it’s amazing what 30 minutes with a piece of scrap lumber and $2 worth of wire yielded.

Garage sale strategy: Go where the hordes aren’t

Today is one of the biggest garage sale days of the year.

An old, established, and relatively well-to-do neighborhood nearby has a tradition of doing a massive 4-block yard sale every September. People put it on their calendars. You never know what you’ll find there.

I went somewhere else.I’ve gone every year the last four years, but I noticed a pattern. Every year I get less and less, and it seems like fewer homes participate. This year promised 50 homes participating, but finding the 10 really good ones in the 50 is tough. The only way is to go to all of them. Figure five minutes per sale, and I was going to spend a minimum of five hours there. Some years I’ve spent longer.

So instead, I picked 10 sales somewhere else and spent about two hours out and about.

I got some good hardware for around the house for literally pocket change. I got some other predictable odds and ends.

But the prize was an under-cabinet LCD TV with radio and DVD player for 20 lousy bucks. The cheapest I’ve ever seen them new is $70. But one with reviews that suggest anyone would actually want to own it costs more like $200, which is about what this one cost new.

I plugged it in at the sale to verify it worked, then brought it home and hooked it up. It works nicely and takes up a lot less room than the 13" CRT we’ve kept in the kitchen for the last few years.

On any other day, I doubt I would have scored that. I arrived at the sale 10 minutes or so after it opened, and was the only one there. You have to be the first or second person there to get anything like that, especially at that price.

Since everyone else was at the big neighborhood sale, I got my chance.

Make Firefox run like new

This is an unbelievable trick. If you’ve been running Firefox for a long time, it gets a lot more sluggish. Here’s how to optimize its databases and give it back its youthful vigor.First, go to Tools, Error Console. Copy and paste this long and obnoxious line in:

Components.classes["@mozilla.org/browser/nav-history-service;1"].getService(Components.interfaces.nsPIPlacesDatabase).DBConnection.executeSimpleSQL("VACUUM");

Click Evaluate and wait. Firefox will appear to lock up, but fear not, when the query finishes, it’ll recover with a vengeance, loading faster, rendering pages faster, and doing just about everything faster.

The difference could be enough to cure new-computer fever, in some cases.

You can close the Error Console window after it finishes.

What this trick does, from a technical standpoint, is dump all the empty space in the databases where it stores all of your data (bookmarks, browsing history, usernames, stuff like that), making it smaller and easier to manage, and, in turn, faster. Whenever data expires, it’s blanked out rather than truly deleted, so the databases just keep on growing over time, contributing to Firefox’s slowdown.

Upcoming

I’m working on a post about SSD myths/misconceptions. Hopefully it will be helpful to someone.

I don’t understand why some people are downright hostile toward SSDs–I haven’t seen anything like it since the hostility I saw towards Amigas in the late 1980s, and OS/2 in the early 1990s.

Maybe it’ll help some people.

Eric Show and the wrong side of history

ESPN has a moving article about Eric Show today. Eric Show was one of several tragic figures from the mid-1980s San Diego Padres who stood in the shadow of Hall of Famer Tony Gwynn, one of the greatest hitters ever.

Show’s family would prefer that people remember him as the millionaire pitcher who was fond of inviting the homeless people he passed on the street to dinner.

But generally speaking, people remember him for a hit he allowed in 1985. A hit to a much lesser man. And nine short years later, Eric Show was dead at age 37.

Show’s tragedy, sadly, wasn’t unique among his teammates. Left-handed pitcher Dave Dravecky lost his arm to cancer. Second baseman Alan Wiggins became the first baseball player to die of AIDS. Tony Gwynn, of course, died much too young as well.

Supposedly the Boston Red Sox and Chicago Cubs are cursed, but their 1980s teams have nothing on that.

But I’m way ahead of myself.

In some ways, Eric Show was a Greg Maddux-like pitcher. He didn’t have overpowering stuff, but he threw a lot of pitches well, and was much smarter than most of his opponents. Show never matched Maddux’s best numbers, but spent most of his career just short of the brink of Maddux-like superstardom. Scarred by a poor relationship with an abusive father, Show’s difficulties bouncing back when little things went wrong turned him into an all-or-nothing pitcher, and those occasional games where he had nothing were the difference between him and guys like Maddux.

Show put together a perfectly respectable career, even if he never lived up to his full potential. During his career, the Padres went from last place to the World Series, and he played a key role in that transformation. Even ignoring what he did off the field, people should remember him as a very good pitcher for a very good team.

Instead, he’s the guy who gave up a record-setting hit. He’s also the guy who hit Andre Dawson with a beanball in 1987. That is, when someone remembers him at all.

But there was a lot going on with him behind the scenes. Show was a gifted musician. Routinely he asked homeless people to join him for dinner. He handed out $50 bills like candy to people less fortunate than him. He was a committed Christian. Finally, he was a deep thinker and only two of his teammates understood him.

Show started falling apart in 1987, when the Padres traded those two friends–Mark Thurmond and fellow tragic figure Dave Dravecky. That was the same year he hit Andre Dawson. I’m familiar with the other side of that story. I was a Cubs fan in 1987, and I’m related to ex-Cubs pitcher Rick Sutcliffe. Sutcliffe had lobbied hard for the Cubs to sign Dawson. When he saw his man go down, Sutcliffe went after Show. The commissioner fined and suspended him 8 games for his role in the brawl.

What I didn’t know was that Eric Show hand-wrote an apology and tried to give it to Dawson.

Abandoned and injured, Show did something completely out of character. The man who talked junkies on the street into going into rehab turned to drugs himself. First it was greenies, which propelled him to his last great season in 1988. But that soon led to crystal meth, cocaine, and heroin. After two barely mediocre seasons, the Padres let him go, and at age 35, he signed with Tony LaRussa’s Oakland Athletics. The ESPN article calls the move naive, but I disagree. Show was exactly the kind of reclamation product that LaRussa’s longtime pitching coach, Dave Duncan, specialized in.

Unfortunately for everyone involved, it didn’t work out. Show didn’t turn into one of Duncan’s success stories.

In 1992, Show was out of baseball and in rehab when he went to see his former teammate, Dave Dravecky, give a lecture. Dravecky wrote two books about his battle with cancer and embarked on a long career as a speaker and author. Dravecky recognized him and asked him to call, but Show lost his number.

ESPN has the rest of the story.

But I agree with his family that Eric Show’s legacy ought to be as a man who took homeless people out to dinner and who forgave and repeatedly tried to reconcile with his abusive father.

I’ve been following baseball for as long as I could read. I’m sure Eric Show isn’t the only baseball player who ever took a homeless person to dinner. But I never heard of any other.

I wanna blow bubbles!

My oldest son’s obsession is blowing bubbles. If he’s awake, it’s what he wants to do. If he doesn’t want to do something, offering to let him blow bubbles if he does that something often works.

The trouble is that an 8 ounce bottle lasts him about an hour and costs between 75 cents and a dollar. That can make for an expensive 3-day weekend, unless you make it yourself.I’ve seen a number of recipes. The recipe I tried may not be the best, but it’s better than any of the commercial formulations we’ve tried.

I took 1/4 cup of Costco dish detergent (it was what I had), 1/2 cup of water, and a tablespoon of sugar, which I stirred and poured into his used bubble bottle.

Most recipes suggest Dawn or Joy. For these purposes, I’m sure concentration matters a lot more than brand. Some recipes call for glycerin or corn syrup instead of sugar. Corn syrup and glycerin aren’t things I have any other reason to keep around, so I used sugar.

The concoction left enough room in his 8-ounce bottle to make it easier to use.

Google says a gallon of Dawn costs $15 at warehouse stores. That would make 64 refills, cutting the cost to about 25 cents a pop. I don’t remember what the Costco brand costs, but it’s probably less than that.

Where I am

I’ve been trying to keep a lower profile online the last couple of weeks. But telling everyone where you are seems to be the rage these days.

I’m in my living room. I’m here a lot.Earlier tonight, I was making toy cars with my oldest son ("Daddy, make more school buses!"). We have a routine. I make them, he plays with them until he gets bored. Sometimes he lets me play too. Once he gets bored with that, he takes them apart. Sometimes he brings me the pieces, which I reassemble into something a little different. As the night goes on, the cars get weirder and weirder.

The game will probably change when he gets a little older and discovers, like my cousin and I did, that you can crash the cars into each other.

After both sons went to bed, I wound down by watching old Guadalcanal Diary videos on Youtube. Guadalcanal Diary was an indie rock band that came up around the same time and place as R.E.M. They were a little weirder, immensely talented, and a lot less successful. The DJ who used to play alternative music on Sunday nights on one of the Top 40 stations in St. Louis in the late 1980s and early 1990s would mix them in very occasionally. I’m pretty sure by the time I’d heard of them, they’d already broken up.

I think their singer, Murray Attaway, could croon with almost anybody. The single off their final album, "Always Saturday," shows off those abilities. But their songs tended to be a little too cerebral, and maybe a little too dark, for mass audiences.

I won’t be posting another update like this one. The routine will be about the same tomorrow. And probably in a couple of weeks, though by then, I might be listening to some other forgotten band.

Editing. Or not editing.

If you were one of the 25 people who read my ramblings earlier today, I apologize. I accidentally posted what amounted to a bunch of disorganized notes. I’ve since edited them into better shape. I still think they wander too much, but that’s a reflection of me, I guess. My writings are all over the place because I’m all over the place right now.

Of politeness and consideration in the connected age

I’ve quit several online forums in recent months, and lately I’ve been noticing a lot of Facebook wars–discussions that just got out of hand too fast. All of this makes me extremely nostalgic for the days of Commodore 64s and 128s, dialup modems, and hobbyist-run BBSs. It was hopelessly primitive compared to what we have today, but for the most part it was polite, and it certainly felt more like community.

DVD players as cheap home media centers

I thought the steady stream of Thomas the Tank Engine, Dora, Bob the Builder, Thomas, Thomas, Thomas, Elmo, Thomas, and Thomas had finally done in our DVD player after almost 8 years.

It turned out the VCR I was running the video through was actually the problem, but what I learned in shopping for a potential replacement suggests I may want to think about replacing it anyway.Modern DVD players will upscale your old DVDs to make them almost hi-def, and have HDMI ports for digital connection to HDTVs. But they do more than that.

Mid-range ($50 and up) players include a USB port, so you can plug a flash drive or hard drive into them, and they’ll play MP3 audio or DIVX video off them.

Due to the United States’ anti-fair-use laws, I won’t tell you how to do it, but what you’ll want to do is rip your DVDs to a USB hard drive, convert them to DIVX, then plug them into your DVD player. Ask Google how. Then you have a library of movies in a 5-inch box and don’t have to mess with discs. That’s a big plus when you have small kids like I do. Plug in the box, turn it on, and pick your movie or show from the on-screen menu.

For ages, I’ve been planning to build a media center PC for just this purpose.

But I think I’d really rather just buy a $50 DVD player and plug a USB hard drive into it. Even though our 32″ CRT TV can’t really take advantage of a modern player’s video capability, the convenience of not fiddling with discs (and no risk of scratching them) makes it worth the 50 bucks. And once LED-lit LCD TVs get affordable, the DVD player will be ready for it when I upgrade.

Update: Rather than buy a pricier DVD player, you might want to consider a $35 DVR, which can double as a media player.
