Quality Depends on Good Communication

Well, I had to hire a contractor to do a job that was a bit too big for me, even when I am well. When that was done, he asked if there was anything else he could do. The exterior basement door was sticking because of some settling and the hinge screws getting loose in the wood after 125 years. I showed him the door and figured he would understand what was needed. Clearly, fill the holes with structural filler and adjust the shims. After all, he was a professional.

Oops.

I had to take a call from work and do a quick fix for them. Less than an hour later, I returned to find he’d smashed off (not unscrewed) the antique cast iron steam-age hinges and put some modern, thinner, plated, light weight hinges in the original mortises! He was about to shave off some of the wrong side of the door when I intercepted him. He left for lunch.

Aarghh! Had he checked with me, I would have explained that the hinges themselves were not the problem. And clearly he has no idea what the market is for genuine steam-age hardware in usable condition to restorers, collectors, and steam punk folks. So rather than just cry about split milk, I thought I’d fume about it here, and share a snapshot of the piece that I was able to pull out of the trash.

The Object at Hand is therefore the remains of this hinge from 1890.

Circumventing Darwin

I picked up a free flashlight from a cheap tool import shop. This handy, hand held Object at Hand is a flashlight, with a  warning label. 😀

To prevent serious Injury:

1. Wear ANSI-approved safety goggles during use.
2. People with pacemakers should consult their physican(s) before use. Electromagnetic fields in close
   proximity to heart pacemaker could cause pacemaker interference or pacemaker failure.
3. Position batteries in Proper polarity and do not install batteries of different types, charge levels, or capacities together
4. The brass components of this product contain lead a Chemical known to the State of California
   to cause cancer and and birth defects or other reproductive harm.

Let’s set aside that I went to Harbor Freight; I do know the quality of their tools. I’ve been mail ordering from them since they only had an outlet in California, over a decade before the Web.

But here we have a hand held flashlight that uses significantly less power than the old EverReady flashlights that we got for free with a two-pack of “D” batteries back when I was a kid. I’m old enough to have gotten the ribbed metal flashlights, before the orange plastic. Those rusted away when a battery leaked.

But the point is not about the flashlight, but about the silly warning label. Sure, I’ve seen the toaster oven warning not to use it in the tub. But these warnings are even more absurd:

Let’s begin with, safety goggles to use a flashlight? Really? This is not a laser pointer, nor does it have the capability to explode. The alkaline batteries that one would find in here cannot be made to explode unless you throw them in a pretty hot fire. Maybe the flexible plastic hook that swings out from the back could do eye damage during roughhousing?

Pacemakers? Granted, they probably use a switching power supply to boost the voltage for the LED matrix. That is, this device probably does produce a barely detectable electromagnetic field. Probably orders of magnitude less powerful than a cell phone. But technically it does produce some radio noise, and by law that means it must need a warning. I suppose.

Then there are several warnings about how to use batteries that I would have thought most kids old enough to read would already know. But what they don’t tell you is, What Kind of Batteries does it need?

And finally, because of California, a warning about the minute trace of lead one finds in brass. Brass is the group of copper alloys with 55-75% copper with most of the rest being zinc. As with any metal outside of the semi-conductor industry, it will have small traces of other elements, including lead. The (WAG) gram of brass in this flashlight would have up to about 0.004 grams of lead. (Here’s an actual analysis of some unspecified brass alloy). But that trace of lead is in there because the extreme chemical processes used to purify the copper and zinc were unable to get the lead out. What are the odds that anything you could do would extract any measurable amount of it?

IMHO, this warning label is somewhere between specious and laughable. Yet apparently required by law in California. Good luck to those members of our species who may need it.

Next stop, purple

You know how when you need something at a store, and then you think of other things to get? Well, my trusty charcoal chimney (as seen in my post Old Tube, New Life a few years ago) had finally rusted to pieces. I’d fixed it a few times over the years, but now the tray was shot, and charcoal could fall right through the sides. But this is not the object at hand.

So I went to smile.amazon.com, and found a stainless steel one that should last for decades for less than twice the price of the rustable one. And while I was there, I needed some low discharge NiMh batteries for our home phones, and a solar light for the garden.

And, well, another pocket camera. I’ve been complaining about my latest one for quite a while. I figured that it was time to stop whining and bite the bullet and buy a replacement.

I’ve been using Canon PowerShot Elph cameras since 2008, collecting a series of them as I burned little dark areas on their sensors by shooting too close to the sun, cracked displays, dinged cases, and chipped lenses. I keep the old ones around because some older models have niceties that they removed from newer cameras.

Like the SD1100IS has built in time-lapse video.

The Elph 110 has 240fps video (used in this video) and 30fps burst mode (good for getting shots of dancers).

They all are pretty much of a size, so I buy them in different colors so I know which one I am grabbing at a glance. I have silver, pink, gold, and black ones.

The time has come for purple. And today’s object at hand (a Canon Elph 360 HS) came in the mail today, and matched the shirt I had on.

Vegan, Gluten Free Ginger Cookies

In our previous episode, our hero was left holding a can of beans. What, our parsimonious person wonders, will I do with these chickpeas? In my previous post I used aquafaba, the juice from canned garbanzo beans, in a manner learned from All Things Considered. I was wondering what to do with the beans themselves, when it occurred to me: Gluten Free Gingerbread! We have a holiday family gathering to which I usually bring cookies. But several members on my wife’s side of the family have medically diagnosed Celiac issues; they must stay gluten free. And then there is that one thin Vegan that seems to be in every family nowadays. I aim to please.

So I did some Googling, and found hints of what I wanted to do, but not one recipe for ginger cookies using canned chickpeas. So I decided to invent one by mixing a few found recipes with the knowledge I gained from my mother and Harold McGee. Plus some experience with a food processor.

But American “Gingerbread” is actually more like the base layer of German “Pfefferkuchen” in that the flavors of cloves, molasses, nutmeg, and cinnamon mostly hide the ginger note. I like the taste of ginger; I like to feel the burn.

So here is my apparently weird, but rated successful even by non-vegan, non-gluten-free friends, recipe:

• One can Garbanzos, drained, rinsed, set in a colander.
• 1/2 c rolled oats (you can use quick oats, or gluten free oat flour)
• 1 Tbsp ginger powder
• 1 tsp baking powder (or 1 tsp baking soda plus 1 tsp cider vinegar)
• 1/2 tsp cinnamon (optional, I think it boosts the flavor)
• 3/4 c brown sugar
• 3 Tbsp melted coconut oil
• 1/4 c minced candied ginger

1. Put the oats and powders in a food processor with a sharp blade. Mill till powdered and mixed. Meanwhile, preheat oven to 350ºF
2. Dump in garbanzos, sugar, oil. Mill till dough. You will need to scrape it down a few times. If using vinegar, add it about halfway through this step.
3. Fold in the ginger candy. I used a separate bowl for this to avoid chopping it any finer.
4. Spoon and press, or roll and cut. I used a fork to press and raise crispy ridges on this first try. Next time the plan is to roll it to 1/4″ and cut holiday shapes.
   
   

   
5. Bake at  350ºF for 30 min for crispy cookies. Try 20 minutes if you want soft centers. INRS

Vegan Meringue “Wasps Nest” Cookies

I was listening to All Things Considered and I overheard a chef discussing vegan cooking. One question piqued my interest: “What do you use for eggs?”

“Aquafaba,” is the answer, “Chickpea juice from canned garbanzo beans is a direct substitute for egg whites.”

My adult nephew is currently vegan, and one family holiday favorite was a meringue cookie that I’ve made since childhood. Here’s the story behind those (indented so you can jump to the recipe if you are so inclined).

In my family, we celebrated the four Sundays before Christmas as Advents. This meant family gathered for some special light meal (latkes, or fondue, smorgasbord, etc) followed by special goodies: Imported German cookies (“Pfefferkuchen”), home made special seasonal treats, etc. My German mother used traditional recipes from an old cookbook. Not only in German (and thus requiring a gram scale) but printed in German Gothic script.

Many of these rich recipes used an excess of egg yolks. My mother, having been raised in an economy significantly worse than the U.S. Great Depression, hated to waste anything. So she found a recipe for meringue cookies to use up the egg whites. They were slightly chocolate and filled with almonds, and named Wespeneste (Wasp’s Nests) for their resemblance to the spiky, papery, chunk-filled objects.

So these not-at-all holiday-esque cookies became a holiday tradition.

So here is the Vegan (and gluten-free) variation on this recipe:

• 1 Can Aquafaba: Juice from 1 can of chick peas (approx. 2/3 to 3/4 cup)
• 1c sugar (cane, beet, coconut, whatever)
• 1/3 c cocoa (more or less)
• 3/4 c toasted almond slivers (or chopped roasted almonds)

1. Whip the aquafaba to soft peaks, preheat oven to 350ºF
2. Slowly add sugar while whipping
3. Sift in cocoa while mixing slower (slower to prevent clouds of cocoa covering the counter and causing coughs)
4. Continue whipping to firmer peaks.
5. Fold in almonds
6. Spoon onto silicone pad, aluminum foil, or parchment on a cookie sheet. Anything oven safe and peelable.
7. Place in oven, multiple racks any location.
8. Turn oven down to 225 (note: Assumes gas oven; electric may be fine to turn off, INRS)
9. Leave in for an hour (less for chewy centers, more for what my little brother calls “‘Splosion cookies.”) These are meringues; the oven is not so much to bake as to dehydrate.

The firmer the peaks when whipping, the more the cookies will hold their shape. Also, this temperature combination sets the outer shape and then lets the interior settle, leaving a hollow area. It makes them more fun that solid meringues.

But here I am with a can of beans. Now what? The answer came to me:
Vegan, Gluten Free Ginger Cookies

What’s a Chick Pea?

This and the following two posts are about a legume. First, a minor reminiscence. Then a couple of unexpected cookie recipes. Basically three posts in which The Object at Hand amounts to just a can of beans.

Back in 1970 my parents took us kids to visit our grandmothers for the first time. We were living in familial isolation in the middle of the U.S. and my two grandmothers were in northern Europe and the Middle East. This story originated at the southern branch of the family.

One food that was new to my mother and us kids was “tahina hatzelem” (my best guess at spelling a foreign phrase I hadn’t heard since childhood.) It was decades later that I learned that in the U.S. this sesame and eggplant paste is known by its Arabic name: “Baba ganoush.”

But back in 1970: We had returned home and my mother wanted to make it. She had no trouble finding the eggplant and sesame paste. But it took her weeks of trolling all the grocery stores to find chick peas. She would search the aisles, and then ask someone. No one seemed to have ever heard of chick peas. Until she went to one smaller market, and a stock boy with an Spanish accent (near as my German accented mother could tell) overheard her ask the manager. After the manager said they didn’t have them, the stock boy suggested that she ask for “Garbanzo Beans.” The manager lit up, and told her where to find them. My mother was both amused and appalled at the absurd name; she felt that foods should have polite and respectable names.

But every summer from then until I moved out (and probably after that) my mother would make a batch of this yummy dip, liberally topped with paprika. This is my earliest association with the Garbanzo.

Chemicals are Missing

I happened to look at a tube of sunscreen slash bug repellent sitting on a windowsill in my home, and the absurdity of its claims have promoted it to today’s Object at Hand.

The front proclaims, “Chemical Free!” This baffles me. If the constituents of the contents are found on the periodic table, it has chemicals in it. Outside of brief existences in high energy locations, like the Large Hadron Collider impact zone, everything on Earth is chemicals. Even the dissociated plasma in arc lamps is chemical in nature.

But maybe they consider “chemicals” to be things with known chemistry, as opposed to the generally unknown complex chemistry of plant products. But there on the back is a typical list of somewhat unpronounceable, organic and inorganic, mostly synthesized, molecules. Chemicals.

I am sure we paid for this stuff, so they were not free. I am sure that the tube and everything inside is made of chemicals, so “free” could not mean “absent.”

It also says it is the #1 Natural Choice. As opposed to, a super-natural one? Anything found in the known universe is a part of nature, “natural”. We’ve even discovered natural nuclear reactors, and any chemical that can be synthesized in a lab can be found somewhere in nature. Turns out, space is full of wacky, complex organic molecules. So, on what scale do they order how “natural” a product is?

To complete the absurdity, it has a banner: “Quantum.” That word means, the smallest divisible unit. Generally, something so small that it requires great sophistication to detect the thing or the difference. Is this referring to the smallest tube they sell?

And after all that, the package doesn’t even clearly state what it does, for how long, or how it is supposed to work. A trite triumph of marketing form over functional content.

In the Thick of it

How many of you remember those old, carbon-paper credit card receipt machines? Revel in the solid “Ka-chunk chunk” sound as the cashier strained to run the slider back and forth, and the waste can full of booklets of carbon paper pulled from the right side of the sandwich of receipts. As a kid I was allowed to take some of those carbons home from stores, to play with fingerprints, and to use for stenciling. Back then, folks didn’t worry so much about identity theft.

But have you even seen one of those machines in the last decade?

Today’s Object at Hand is a new debit card, complete not only with a magnetic strip (tech from the 1970’s) but also a somewhat secure chip (based on the late 1990’s tech now considered obsolete in Europe). And, what is this? It still has the 1950’s legacy support of embossed information! Why, you may well ask, do I make a point of this?

I like a thin wallet. The embossing increases the thickness of each card by 50%, and the friction to drag it out of a wallet pocket by noticeably more than that. It wears out the pocket or adjacent cards faster, as well as frustrating the user when too many get packed in there. And it serves no (expletive) purpose. Well, little potential purpose.

Had I a flat card, and needed to purchase from some Luddite (who also does not take cash, or checks, and has neither the free stripe reader or the cheap chip reader available to anyone with a smart phone), they would be forced to hand write my name and card number on their multi-part receipt form. I’d happily do it for them.

Fortunately, I could walk in to my bank and get a flat version of the card this morning. All the same information at 66% of the thickness. Happy ending 🙂

Socket To Me

Or: All Your Base Are Belong to Edison

As I was putting up lights for the Solstice/Yule/Christmas season this year, I found that my porch light would not work right. I had unscrewed the bulb to screw in an outlet to power the porch-hung wreath, and could not make it work. I had replaced a (CFL) bulb a month earlier, and suspected that the fixture rather than the bulb was at fault. Now, I was sure of it. So I used an alternate source for the season.

But then we had a warm day in January, so I set up a ladder and took down the light. Yes, I first identified the right breaker (that took a few tries) and shut off the power.

The fixture seems to be from the 1940’s or 50’s.

I had put a dusk-to-dawn sensor on it in 1990. Birds had nested upon it, and insects apparently made themselves at home behind it.

So down it came, and I worked out how to disassemble it. The screws were rusty, but functional. It needed a good cleaning.

But as I took it apart, it became apparent that the problem was not the wobbly nature of the light socket, but rather that a tubular rivet in the interior of the socket had fatigued away, failed. This was the critical problem. Here you can see the two rivet positions for the Edison base shell, one without a rivet. The missing side is the one to which the neutral power line connects. So the light worked if I pushed it in to touch the rivet, and only then.

So what to do? I hate to replace something that can be fixed. Fortunately, I am a bit of a hoarder. I had saved the light fixtures from a burned out, water damaged ceiling fan a decade ago. I found this remnant and pulled out its socket. See what the rivets are supposed to look like:

The iffy news is that the wires on the “new” 1980’s socket are a bit corroded. But my experience as a tinker and my degree in electrical engineering led me to think this was not a real issue. With CFL’s and LED’s it will never be carrying as much power as it was designed to.

The good news is that the holes, indents, and threads of the 1980’s socket matched the mid-century light fixture. A perfect fit.

So the true Object at Hand is the late 1800’s designed electrical screw-socket to mount light bulbs (generically known as an Edison Base) that are still made from ceramic and brass.

As Ice Balls Age

Last winter I had a whim and a handful of cheap balloons, so I made a set of colorful ice balls. This post does show how to make them, and what mistakes I’d made. But unlike other posts you’ll find on making ice balls, I show the odd thing that happens as they age. So read to the bottom.

First, wear gloves if you don’t want colorful hands for a week or so.

Then make sure that you have a place to put them to freeze. I chose to do them naturally outdoors, and will explain what I did wrong there below.

So, take a balloon and put a few drops of food coloring in it. Then fill it with water, somehow. Caution, if the balloon pops, you may get sprayed with permanent dye. Wear an apron, or clothes that you don’t care about. (Here’s my video that these pix came from)

Gently place the jiggly ball of dye in a cold place. Below 25ºF is best. If you use a freezer, put them in a bowl or something that will catch the liquid if the balloon fails. I put them on a stoop in the snow. Unfortunately, the warm balls melted the snow and they rested on the warmer concrete. So they froze unevenly, and I tried to move some of them too soon. Next time, I will place them on a chair or bench or anything allowing an air gap between their resting surface and the ground.

But most were solid enough for me to pop and remove the balloons. The blue one up close ruptured and leaked, but the other blue one bounced to the bottom of the stairs without losing its cool.

But I did get a nice set of balls to stack as a decorative accent. They got snowed in, and the snow faded and stuck to them over the course of a few weeks.

But note this weird thing! When the temperature got up close to freezing and then cooled at night for a few days, the dye settled within the solid ice!You can see the distilled, purer water ice at the top, and the more concentrated color collecting lower down.

So The Object at Hand today is either the literal ice balls, or the lesson in physics showing how simple natural processes can cause dye to un-mix from frozen water; an apparent reversal of entropy.

This process is similar to Zone Melting, by which silicon is ulta-purified to make semiconducting wafers to make the chips that make it possible for you to read this.
