Acquired — Argus C20 Camera

Tuesday, July 3rd, 2012

Here’s something kinda fun; an Argus C2, my newest old camera find.

I picked it up for cheap at a local thrift store a while back, the latest in my decades-old penchant for old cameras. I think my collection — if it can be called that — started with my grandmother’s Brownie Hawkeye, which somehow ended up in my possession — I have no memory of exactly how — after she passed away.

I actually used that camera for a time; it didn’t produce terribly high-quality photos, but it was kind of a novelty in the day when Instamatic cameras were more the norm and 35mm cameras were the hot thing. Eventually it became more & more difficult to get film for it, and even more difficult finding a lab to process the film & make prints, so… On the shelf it went, along with some flashbulbs. How many people remember using flash bulbs?

From that start, I’ve been adding to the collection by keeping an eye out for old cameras at rummage sales, antique stores & thrift stores. There are now (I think) a couple dozen of them, plus some assorted light meters, lens filters, flash units, cases, etc… There are a couple of old movie cameras in the bunch, and a Polaroid camera or two. The newest “antiques” I have are a very early Fuji digital camera and an Apple QuickTake 100; in computer lifespans, they ought to be considered antiques by now. Finding a working computer they could interface with would be the big challenge now, so by that measurement, they qualify.

I was glad to find the Argus C2 though; I had another one like it years ago but gave it and a nice light meter to my brother-in-law as a Christmas gift. That was well before the ubiquity of digital cameras, and he actually got a fair amount of use from it (which was better than the shelf duty it served at my house!) The new(?) C2 is in slightly better shape (from what I remember of the old one), probably due to the heavy leather case and padding that came with it. It’s a heavy camera, built back in the day when heft meant “durability” and “quality”.

When I look at the old cameras, especially the 35mm cameras, I can’t help but admire the craftsmanship that went into them. These things were designed & built long before CAD was ever even thought of, and probably assembled by hand. The glass in the lenses was ground using really old-school technology, and even the tiniest metal parts… who knows how they were manufactured. Most were made of metal, with a smattering of paper products for the bellows and leather to dress them up a bit. It’s a wonder to me that the softer parts on these cameras have survived so many years in such good condition. Some of the lower-end cameras from the ’30’s – ’50’s used Bakelite for their cases; today’s cameras are mostly plastic with some metal, and lots of silicon for the electronics in them. If you were to drop one of the older cameras, chances are it would get scuffed up a bit but keep working; if it didn’t work you could often take it somewhere to get repaired. Today’s cameras — especially the under-$100 cameras — are for the most part disposable. Getting one repaired would cost more than replacing it.

For all the benefits and niceties of the older cameras, it would be hard to go back to film. The digital camera was really a game-changer in a lot of ways. In the mid-1980’s I spent a pile of money on a Canon T70 35mm camera and a couple of lenses for it. I could take some decent photos, but I never really put in the effort to learn all the tricks because with film you’d have such a time gap between when you set up a shot and when you’d see the result, not to mention the cost of the film and developing. With many digital cameras you can enable most all of the same controls as with a nice 35mm camera, but with digital you can see your results almost immediately.

That said, I still haven’t taken the time to learn many tricks with them; it’s mostly just point & shoot. Someday…

Here’s something fun; a ‘manual’ straight from Haynes on Wallace & Gromit’s Cracking Contraptions!


I’ve probably enjoyed the Wallace & Gromit claymation movies more than the kids; Gromit is probably the most entertaining of the pair, even though he never speaks a word.

A Nocturnal Work Aid

Monday, November 29th, 2010

I picked one of these headlamps up on sale at Lowe’s yesterday for $12 — it was the last of a Black Friday special on the shelf — and it’s already earned its keep, although my neighbors must think I’ve lost some marbles… Tonight Bryce & I spent the last hour of the day (11 to midnight!) hanging Christmas lights on the outside of the house (before the weather turns sour tomorrow) and yesterday I used it to finish up the front end rebuild under the 735i; finished that one up about 10 pm.

These headlamps are just a huge help in working on a car, and so much better than the old-fashioned trouble light. Wearing it on my forehead, it puts the light right where it needs to be without a light fixture getting in the way, as is the case with a trouble light. I turn my head, the light goes with it so I can see what I’m looking at. I haven’t used it during the day, but it would even being a huge help then; if I’m under a car it seems the light is never good, and this thing will do the same trick then.

My new headlamp has three lighting modes,

  • Bright 1-watt LED spot; ~ 45 lumens, 11 hour run time
  • 2 bright Nichia LED’s flood; ~ 28 lumens, 50 hour run time
  • 2 bright red night vision LED and 75 hour run time

About the only thing I don’t like about it is the switch; it’s a push-button switch on the top of the lamp. One click turns on the 1-watt LED, second click turns on the red LEDs, third click turns on the flood light, and the fourth turns it off. The switch is also a bit difficult to click, which may be a defect of some sort with my particular unit. But the don’t-likes are pretty minor issues; all in all it’s a great little tool.

I do think I’ll put some day-glow orange or pink paint on it though so it doesn’t get lost like my last headlamp did.

A Handy Mic Stand

If I ever become a death metal rock star (yeah, that’s me all over!) this stand will accompany me in every concert. So awesome.

Interesting back story on the stand in the Wired article.

Video Game Driving Challenge

Wednesday, April 7th, 2010

My kids have asked me before why it is that driving a computer-simulated car in a video game is so much different than driving a real car. My off-the-cuff answer has been that the controls in the video game are usually much cruder than those in a real car. Imagine if you were driving down the highway and your steering was controlled by two buttons for left & right, the throttle was an on-off switch, as was your brake. Controls like that in a video game make driving pretty dodgy, but if it were in real life… I’m glad I don’t have to share the road with vehicles like that! Cars would have to be just as indestructible as their game-world kin.

The guys in this video were wondering something similar; how it would work if you tried to control a real vehicle from the typical video game driving perspective. The results, even with normal vehicular controls, are pretty hilarious. (There is some foul language in the video, so keep the volume low or headphones on if there are kids nearby!)

I’m guessing the drivers could improve with a little practice. Or maybe a lot of practice.

I Want Me An iPad

Apple just introduced the iPad, and I want one. You can read about all the details and watch the demo movie in lots of places, so I won’t spend any time on that…

I just want one.

Apple’s Magical Mouse

Wednesday, January 27th, 2010

I helped a friend set up her new 27″ iMac last weekend, and it came with the coolest new mouse… The Apple Magic Mouse.

magic_mouse

The mouse is the button, plus it has no scroll wheel, but you can use it to scroll up, down, diagonally and sideways. Comes in one color, wireless Bluetooth, but right now is only supported for use on a Mac (Windows support is coming!) The way it works is similar to the MacBook trackpads with multiple-finger functions, but that is a couple of steps above the trackpad on my getting-older-by-the-day PowerBook G4! I want one!

Actually, these would be great for use at work; seems like I’m replacing a mouse somewhere in the building at least once a week. The failures are usually with the scroll wheels, and the Apple Mighty Mouse with its tiny little scroll ball is the worst offender. The Magic Mouse with no external moving parts should be nothing but great! And as great as this mouse is, the tablet computer that Apple is expected to announce should be nothing less than amazing.

Getting Back Your Lost Camera

Tuesday, January 5th, 2010

This is not only a great idea, it could be a real hoot putting it together!

A Pictorial Guide to avoiding Camera Loss

Have you lost your camera recently? Mislaid it somewhere in a national park? Left it in a taxi? Dropped it in the gorilla pit? Anyone can be a victim of the thoughtlessness and/or sleepiness that can lead to Camera Loss…

Of course it’s not sure-fire, but it at least gives you a better chance of getting back a lost camera than the ordinary assortment of anonymous images normally found on a camera.

All kinds of clever things come to mind for a little slideshow on my camera… The only problem I’d foresee is having to change my practice of letting iPhoto remove the photos from the card when it’s done importing them. But I can change.

Robots in the Cowshed

Wednesday, December 9th, 2009

A couple of years ago my sister-in-law met and married a Dutch dairy farmer; around here that wouldn’t be much of a feat because there are plenty of Dutch dairy farmers in Northwest Iowa… but they now live on the farm in Holland! Keeping up with family means Skype and long airline rides are pretty much the norm. They made the trip back for a holiday visit a couple of weeks ago, and had some fun showing off (via photos & video anyway) the new toys they installed in the dairy barn; two milking robots.

astronaut-3

The robots were designed & built by Lely, a Dutch farm equipment manufacturer. And they truly are robots; aside from routine maintenance, they require no human intervention to milk the cows. They and the cows just hum along, day and night, and in the process milk production is bumped up by a decent amount, which allows the dairyman to increase the size of the herd and focus on other details of running the farm. They really are pretty amazing:

  • The cows are trained to walk into the machines when they feel the need to be milked (on average, 2.8 times a day)
  • RFID tags allow the machine to recognize individual cows as they enter.
  • A portion of feed is dispensed that is custom blended to meet that particular individual’s nutritional needs.
  • The robot cleans the udder & teats,
  • It then uses a laser tracking system to locate the individual teats and attaches a suction device to each and begins milking.
  • When finished, it detaches from the cow and turns her loose from the stall.
  • The robot then cleans the suction devices and prepares for the next cow.
  • As the milk is drawn, the quantity tracked, and the chemical composition is analyzed to diagnose potential health problems in the cow.
  • If the analysis shows the milk fails to meet predetermined quality standards, the milk is discarded.
  • The computer controlling the robot also keeps statistics for the entire herd, allowing the dairyman to keep track of trends and potential issues with individual cows.

Since the thing is controlled by standard PC hardware, they were able to pull up the machine via VNC to check up on things; it was evening when he was showing this to me, but about 3 am local time at the farm, and we saw that a cow had just stepped into the machine. Apparently one of the things that helps to boost milk production is that the old way of doing things — milking twice a day — doesn’t really fit with a cow’s natural cycles, as is shown in the stats with the robot; on average, they will go in to be milked 2.8 times a day. And they will go in at all times of the day and night, whenever they feel the need to be milked, which I would think makes for happier cows!

The video below shows the machine in action;

The Texaco Fire Chief Helmet

Sunday, December 6th, 2009

Somebody at work was complaining the other day about feeling like she hadn’t accomplished anything that day because she spent all her time “putting out fires”. I could relate; I have days like that pretty regularly. But with Christmas approaching, the thought occurred to me that it’d be fun to get her a toy fireman’s helmet as a gag gift, and that led me to remember one of the coolest toys of my childhood, a Texaco Fire Chief helmet.

TexacoHelmet1

This was not just any plastic toy hat; it had an adjustable head strap, and a microphone with an amplifier and speaker built into the front of the helmet. I don’t remember when I got the helmet; probably a Christmas gift that kinda blended in with all the other gifts, not leaving any distinct memories. I also have no idea what happened to it, but I’d bet it was jettisoned back in 1977 when my family moved from the house I grew up in — a lot of stuff disappeared during that move. By that time I had pretty much outgrown that toy, but these days I’d sure like to have it back, just for old time’s sake. I do remember being frustrated with it not working, but if I had it now, I bet I could get it working again.

TexacoHelmet8

I found several helmets like mine up for bids on eBay (of course); the one pictured was in particularly good condition, and had some great photos (that I could actually borrow; it’s eBay is making it pretty tough to link or directly download images from auctions these days.) I’m really tempted to bid on it.
