    First IR light for the XTi


    2013 - 03.31

    So it’s nothing too amazing yet, but here is the first alright looking shot from my Canon XTi which was recently modified with the removal of the internal Infrared-block glass that covers the sensor.  I used a 720nm filter to block all visible light.  So nothing but infrared here.  Not really an amazing shot but I’m pleased with how the plants look nice and white.  I need to play with it more and maybe try a timelapse if I can find a cool subject.  But hey, it’s working, neat!!

    I did a relatively mild post processing on it.  Since it was at sunset, it wasn’t a good candidate for the red/blue channel swap like people do to make the sky look blue.  That’s more suited to afternoon images.  I still have a lot to learn when it comes to the subtleties of IR post-processing.  But I’ve started learning and that’s sweet.

    SimCity 2013: The Phantom Menace – putting the “limited” in Limited Edition


    2013 - 03.21

    So I wrote a little blurb shortly after the launch of Simcity, but the news on this game has been evolving so rapidly that what I’d written felt irrelevant before I could even publish it.  It’s been a strange tale.  I haven’t actually bought the game yet, and that turned out to be the right call.  As I’ve observed the commotion, my feelings on the game went from major excitement, to pessimistic disappointment, and eventually to my current ambivalence.  The pre-release hype made it seem like this was going to be a return to the glory days of one of the best franchises in all of gaming, and then the reality set in at launch: servers were crushed under the initial load, then once people finally did get started playing, the gameplay was revealed to be broken on multiple levels.  I was super excited about this one for months on end, and now I wonder if I’ll even get it….

    I won’t even begin to chronicle the plain-out-weird tale of corporate-newspeak from EA/Maxis and their apologetics for why the game absolutely had to be online-only.  That story will probably go down as a textbook example of how not to handle a PR meltdown.  The superbly-written and eminently-thoughtful gaming blog Rock, Paper, Shotgun has had unbeatable coverage of the whole fiasco, which is certainly worth perusing, if you’re interested.  Besides, they’re the best PC gaming blog in the biz today, check em out.

    A couple weeks in, it sounds like most (but not all) of the server-related killjoys have been addressed.  But perhaps more nefariously, the game’s underlying AI seems to have deep problems with pathfinding.  Epic traffic jams that span whole highways between city.  Fire trucks stuck in the station, or simply never arriving.  Pedestrians wandering in circles endlessly around the same intersection, blocking all traffic.  Trade frozen.  Bus pileups as far as the eye can see.  Once your city gets big enough, these unfixable problems begin to break it.

    There are other weirdnesses that make no sense: it’s possible to build nothing but roads and residential zones, and end up with a 60k population… in spite of the fact that your city has no commercial zones, industrial zones, power, water, sewer, trash, police, hospitals, etc etc. 

    People have have also lamented that city size is much more restricted than it ever was in SC2k and that disasters cannot be disabled.  Those are overshadowed further by the downright baffling design choice that you can’t even save a copy of your city… which used to allow experimentation with the freedom of restoring to an earlier save-state.  Your city data is not stored on your local computer, apparently?  You have no possession of the content you create now.  That’s just… deeply unfortunate. 

    In spite of all this, odds are I’ll end up buying this game in good time, assuming they can fix the worst of the pathfinding problems.  I’m glad to be reading all this trash-talk before I ever touch the thing.  No game has a soft spot in my personal Venn-diagram of nostalgia/videogames the way Simcity does.

    I remember as a grade-school kid, staying after school for hours to play the original Simcity in the computer lab, since home computers were a rarity in those days.  One time no one knew where I was, and it even prompted a moment of panic until they found me at the PC, just building my city again.  Then when my best friend got Simcity for his SNES we played the dickens out of that, even with lots of other games vying for attention.  We would take turns building and strategizing, laying on the living room floor for hours while his parakeets cheeped and that same music looped over and over.  SimAnt was another addictive one for me when we eventually got our first home PC.  Taking over the whole yard and eventually forcing the humans out of the house was strangely gratifying, and the game somehow made ant-trivia fascinating.  Then fast-forward to junior high when Simcity 2000 (aka SC2k) came out… whoooo, I don’t even want to know how many hours went into that.  One of the all-time top-10 on all platforms, if you ask me.

    So it’s tough not to approach a new Simcity with giddy overenthusiasm, reminiscent of how I probably felt in the theater watching Star Wars The Phantom Menace for the first time.  Sure, all your favorite tropes are here, but uhhh, you’d better tame those expectations: childlike wonder is by no means guaranteed!

    And how could it be, really?  Part of what made Simcity 2000 such an amazing powerhouse was the fact that I played it at a point in life where I was old enough to grab my bike and ride off to any part of town, yet too young to be expected to work; a moment in life when free time was endless, and the relatively-new world of 3D videogames was a fascination with few rivals.  There was all the time in the world to build that perfect masterpiece, then realize all the oversights you’d made in dreaming it up, tear it all down, start over, and build the real masterpiece this time… ad infium.

    Looking at the screenshots of people’s creations (those who have been able to play) brings back a wash of fond recollections of the old Simcities.  This series is sort of the original and greatest “sandbox” game.  One with no win or lose condition, no time limit, no missions to complete, just your imagination.  I really look forward to spending some time in Maxis’ latest iteration of that wonderland I used to get so lost within–I’m just tamping down my expectations.  This is Simcity: The Phantom Menace.  And thanks to the wonder of modern technology, you can’t actually BUY it.  You can only RENT it from Electronic Arts.  That is, when they decide to eventually shut down the servers for good in some years time, that’s it, everyone’s done.  There will be no dusty box in the closet with a CD in it that will allow you to reinstall a working copy.  Nor will there be a stack of 3.5″ floppy disks that got lost for years, only to be found under the bed one day, allowing some magical time warp back to your old experiments, quirky half-successes, and weird ideas.  Those save games kept that time portal open, in a way that few toys could–your LEGO creations could never rebuild themselves into a badass spaceship you created that one time, and the particles in the real-life sandbox of your backyard can never reassemble into the sweet castle your pal Jake made with his tower-shaped bucket.  There is a euphoria in rewinding.

    Those days are gone.  The future is here, and what’s new isn’t always better.

    Instead of a sarcastic “Thanks EA” I’m going to do my best to simply enjoy Simcity 2013 at face value.  It’ll never be able to touch SC2k in terms of pure addictive thrill.  And when it’s over it’s gone forever.  I’ll make a point to enjoy it in the moment, going in knowing that’s a very pretty, but ultimately much smaller, more limited world than my nostalgia wants to paint it.

    That Vinyl Sound: The Marantz 6100 Turntable w/ Grado Green & +1%


    2013 - 03.17

    So I picked up one Svelte (with a capital S!) looking turntable a little while back: the Marantz 6100. It had been up on Craigslist for quite some time and I had been eyeing it up, especially since it would match my Marantz amp I like so much. Finally I pulled the trigger. Immediately when I got it home I started noticing a series of issues. This post chronicles all that I’ve done to upgrade and fix it, for anyone who should want to do the same to theirs.

    First thing wrong with it was that only one channel worked. Yikes, that’s a showstopper! Step one was to diagnose: swap the L/R channels as they were connected to my amp to make sure it was the turntable at fault and not the amplifier. It was the turntable. I took the bottom off and used the “beep”/continuity test setting on my multimeter to see where the signal was getting lost. Note that on older turntables like this, with no internal pre-amps, the four connecting pins off your turntable needle/cartridge are, electrically, connected directly to your receiver/amplifier. That means if you’re missing a channel, it’s a continuity problem: The guts of the turntable are simply wires.

    First, I checked the continuity between the connections right at the needle and the solder joints on the inside of the deck. All beeped, so they’re good. Then I checked the solder connections to the end of the RCA ring/tip connectors. Sure enough, one was bad! I was surprised that old RCA jacks would actually fail like that. Hmph. I took a spare RCA cable, and cut off one end. Then I stripped the wires, revealing four different wire paths. I unsoldered the old one and soldered in the new one, making sure to leave a stress-relief knot, so the cable couldn’t be yanked out by accident.

    Second thing I noticed was that the speed of this turntable is slightly slow. I searched around online and found that this is a well-chronicled issue with the model 6100 turntable. It’s driven by an AC motor, so a simple adjustment of the input voltage to the motor won’t remedy this issue. Somewhere online in a forum I saw someone recommend getting a slightly shorter belt. I called a few hi-fi stores and came to the conclusion that 25″ belts are common but 24.9″ belts, in fact, do not exist.

    Then I got the idea of adding something to make the motor shaft very slightly larger in diameter, since that would effectively make it turn the belt faster. Scotch tape, maybe?? Sure enough, it works! At first I added two layers of tape and now my speed went from like 5% slow to like 5% too fast–a thin layer sure goes a long way. I took off one layer of the scotch tape so now it’s just a single loop around the motor shaft. With only one loop, now the turntable runs very, very slightly fast; maybe like 1-2% faster than normal. It’s the kind of thing where, if you’re listening hard for it, you could pick it out with effort, but if you sat down not knowing that the table was ever so slightly fast, you’d probably never notice.

    At first I wondered if it would annoy me (5% too slow DEFINITELY annoyed me!) but after listening to a whole bunch of albums, I think I actually enjoy everything sped up by an almost imperceptible amount. It’s not enough to affect the pitch of familiar records; or if it is, being slightly sharp is less offensive to my ear than being flat. It does add a subtle extra ‘kick’ or energy, having that increase in tempo–an extra bpm or two. I’m digging it!

    Lastly, I was getting distortion in the sound, like the signal was being overdriven or something. I figured since the turntable is nothing more than wires and mechanical support for the stylus, it was probably the stylus. Spoiler alert: it was. The old stylus was a Pickering VX-15 with a dust brush on the front. That dust brush seems like a great idea in theory, but it sort of sucks in reality: seems like it makes the record skip more, and you need lots more tracking force to prevent that. I’m not sure how old that needle was, but from the looks of it… OLD.

    The Pickering was swapped out with a Grado “Green 1” cartridge. Ka-BAM! This baby breathed a whole new life into the 6100. The anti-skate weight was missing from my deck, so I improvised with a couple zinc washers and some thread. I kept getting skips at the very start of every record, even when I had a lot of tracking force on the arm. Adding the anti-skate weight got rid of those skips at the beginning and allowed me to dial back the amount of tracking force needed. It’s still probably too much right now, but it is nice not getting any skips at all even on records which have known spots prone to it. I’ll keep dialing it back in the weeks to come.

    The 6100 has two simple but nice features that I’ve enjoyed: auto-return and auto-shutdown, and buttons to toggle between 33/45 rpm. My other deck, the venerable Pro-Ject Debut III doesn’t have either of these. Auto return/shutdown means that you don’t have to worry about accidentally letting the turntable skip on the last groove all night because you forgot to shut it off, which I’ve totally done. The 33/45 buttons are a very basic feature the Pro-Ject lacks–you actually have to remove the platter and move the belt by hand, which gets old. Maybe that sounds lazy, but you end up yanking on the spindle too much to get the platter off, and I worry about long-term wear that might be causing. It just makes me nervous doing it, so I listened to less 45s on that deck. No longer!

    But oh man, this Grado Green cartridge is awesome. The Pro-Ject Debut III has an Ortofon OM 5E cartridge, and that turntable sounds excellent. For the Marantz, I wanted to get a different brand, for the sake of sonic variety. Since I love my Grado headphones, it was a logical choice to try out their cartridge line. I’d describe the Ortofon as the “cleaner” of the two, and the Grado as the “warmer” of the two. That said, it’s not a jaw-dropping difference between them.

    I hooked up the headphone extension cable and put on my Grado SR-225 headphones for a long listening session this last weekend… now that was really enjoyable!! Laying on the carpet with my eyes closed, blasting familiar recordings and oh yes, hearing a bunch of new details within them, thanks to yet another different listening setup. It’s chicken soup for the soul, just doing nothing but soaking in the awesome sounds of your favorite albums. After the soldering, reassembly, and tweaking this is the reward; not critical listening but blissful listening. I’m going to make it a point to just hang out and listen to records over the next few weeks, reaquainting myself with the collection again and enjoying the tunes. That’s what it’s all about!

    What’s redder than red?


    2013 - 03.02

    Ever since I got my wonderful Canon T3i a couple years ago (which I STILL think is the sweet-spot in DSLR price/performance/features), I’ve had a perfectly good 10MP Canon XTi body which has been essentially gathering dust.  What to do about this…. I could sell it, although unfortunately, older generations of DSLR bodies depreciate pretty severely  in spite of the fact that it’s still eminently capable.

    A better option: convert it to an Infrared body.  This procedure can be a DIY modification, although it is NOT for the faint of heart.  I’d been thinking about this for a long time so I was excited when it came up in conversation that a coworker of mine repairs/resells DSLRs as a hobby.  It sounds like this might actually happen sometime in the next few months.

    In the meantime, I noticed this really badass timelapse video shot with an infrared DSLR:

    There’s a great explanation on Bad Astronomy of why thing appear they way they do in infrared.  Basically plants reflect a lot more infrared light than any other color–including green!  When you get these photos out of the camera, they appear almost all red in color, so heavy-duty post-processing is needed to get these greyscale scenes with blue skies.  I’ll need to learn about all that to get to the point of making videos like the one shown above, but I don’t think it’s anything beyond my abilities.  Time will tell, but it’d be awesome to make something like this…
