Adventures in Homeownership: Basement Lamps

The original owners of this house lit the basement with 4 naked-bulb "fixtures" like you'd expect to find hanging down in an unfinished basement or a garage.  Rather than hanging, the lights are mounted horizontally between the rafters.  Aluminum foil is nailed to the sub-floor and surrounding timbers.  Transparent prismatic sheeting replaces the drop-ceiling "tile" that would be below the bulb.

This doesn't work as well as I'd like.  The light source is above the ceiling.  Little of the light falls directly into the room, most hits the aluminum foil.  The foil is old, badly crinkled, and mounted to flat surfaces -- so most of the reflected light doesn't even make it into the room.  Quite a bit of it goes to illuminate the area above the ceiling.

Naturally, I've been trying to address this for some time.  Tried reforming the foil.  It's harder to shape multiple pieces of old, beat-up aluminum into a bowl shape than you might think.  The best I was able to make resembled a tassel-less fez with a wire frame.  Even then, I had trouble hanging it in such a way as to direct the light where I wanted.  I looked at various clamp-on worklights, but the bowl-shaped ones all have the bulb entering through the center, not the edge.  With the horizontally-mounted fixtures, these would direct even more of the light away from room.  The metal reflector from a trouble-light would work.  But I couldn't find just the reflector for sale, only new, complete lights.  Those are too expensive to sacrifice for just the one part.

lamp_assembly.jpgWent to the Livingston County Habit for Humanity ReStore today, looking for a hot glue gun and a heat gun.  (Great place to look for tools, if you're not too specific and willing to root-around in dusty, dirty boxes.)  I picked up a couple of double-bulb fixtures, on my way to the tool section.  Figured I could at least double the light if I couldn't direct what light I already had.  Then I saw 2 of these.

I don't know what this is intended for, but it's more-or-less exactly what I needed.  With the judicious application of wrench, screwdriver, tin snips, hammer & prybar, I removed everything from the large square.  That left me with a square mounting-bracket containing a concave reflector with an opening in the side for the bulb.
lamp_installed.jpg
Took a little work to get it into the right position, and secured there.  But the end result is very close to what I hoped to accomplish.

So, for $10, some left-over screws & nails, and the obligatory swearing when the drill doesn't fit*, I fixed 2 of the 4 lights.  I didn't even have to rewire the fixture!


*Gimlets!  One of these days, I'll remember to leave the drill and not have to go back for the gimlets.  Pilot holes in tight spaces are much easier with them.

LED Replacement for Microscope Bulb

| 2 Comments
Received the LED replacement for the microscope's old, presumed tungsten, bulb.  It's the silver-color bulb in the left-center of this image:
microscope_test_rig.jpg
I wanted to test the bulb before I installed it.  No point in fitting it to the 'scope if the AA batteries won't power it.  I don't have a power-source.  So I scrounged some speaker-wire, taped the AA's together, and taped the speaker-wire onto the ends of the "battery pack."  The voltmeter confirmed I had 3V power at the end of my test leads.  Just for giggles, I applied the leads to the old blue bulb.  As I very much expected, the old bulb didn't light.  (Which is good -- now Nicole won't kill me for purchasing an unnecessary replacement LED.)
Lit_LED.jpg
When I touched the leads to the LED, it lit.  Huzzah!  I have a working bulb, that can be powered by the 2 AA batteries that fit into the microscope's base.
LED_dark.jpg










So why light?!?  That's the LED, installed in the microscope.  The batteries are in place.  I confirmed I have power at the bulb contacts, and at the bulb.  It's the same batteries, the same LED -- the only difference is the wires.  Instead of the test leads, power's through the wires in the microscope.  And those are working, because I have power at the contacts.

I just don't understand it.

Microscope

New Tool/Project/Thing!
microscope_fullkit.JPG
While visiting Nicole, we went to the Goodwill Store (great place to get a printer, if you need one).  This was in the locked "really cool stuff" display, along with a bunch of games, a couple of RockBand/Guitar Hero controllers, a Wii Fit balance board, and a load of jewelry.  The mirror worked, I could see through it, the knobs turned easily, and it was $15.  How could I go wrong?  So Nicole indulged me.




microscope_front.jpg
As you can see (click), this is a JASON Model No. 712 Deluxe 900x Zoom.  Monocular (single eyepiece) with a 3-objective turret and both a reflector & bulb illuminator.  i.e., a basic student microscope from the 60s.  It's made of non-ferrous metal, not plastic, and chrome where anti-corrosion plating makes sense.

The kit is leather-over-wood, with flocking on the inside.  Some of the tools are missing.  The spatula, tweezers, scalpel, and some metal pipe-thingy are present.  There are no slides, prepared or otherwise.

The electrical socket (first picture, on the base, near the connector) appears to be in good working condition.  I was able to measure 3V AC at interior points.  I was disappointed to discover the transformer (the gray brick in the first picture) is only a step-down.  It drops the wall-current from 110V to 3V, but it doesn't convert it from AC to DC.
microscope_lamp.JPG
The illuminator is, in my ignorant opinion, pretty neat.  One surface is a mirror.  The other holds a blue-coated "classic" flashlight bulb.  The metal ball-bearing-looking thing on the side of the illuminator is a contact-switch.  When the bulb-side is uppermost, the ball's held against a small plate built into the base.  That completes the circuit and energizes the lamp.





microscope_base.JPGThis is meant to be a portable device.  In addition to wall-current, the lamp will run off of 2 AA batteries.  Space for the batteries is in the base.  I checked these, and the electrical connections appear to be functional here, as well.  Which is good, because here's where the complications begin . . .






Microscope_eyepiece.JPG
First, some previous owner (or maybe high school students, who knows) didn't understand how to tighten the screw holding the eyepiece to the barrel.  It's been over-tightened so many times, there are holes gouged into the fitting.  But, the holes are all in 1 quadrant.  So I just rotated it and gently tightened the screw.






Microscope_bulb.JPG
The bulb is burned-out.  Not surprising, given its probable age.  But I can't find an exact replacement.  Apparently, the bulb uses a tungsten filament.  These are no longer used because they consume a lot of energy, get very hot, and produce yellowish light (thus, the blue corrective film).  No one uses these anymore.  Student-grade microscopes use LEDs.  (Low-end pro-models use flourescent, and better models use remote halogen light sources with positionable fiber-optic tubes.)  I was hoping the transformer was also a rectifier.  Unlike bulbs, LEDs aren't able to run on either AC or DC.  Not a big deal, I just have to find a cheap LED that'll fit into the bulb socket, and then run it only on batteries.  (In fact, I found and ordered such a bulb.  It cost a few cents less than the microscope.)  Now I just need some slides.

Maybe Aidan & I can look at whatever's living in goopy pond water in a few weeks . . .

The Great Divide in the front yard

This is a Green Heron (affectionately known around my house as "Sparty").  (It might also be an American Bittern.  Not really sure.)
Green_Heron.JPG
This isn't a great image, but Sparty doesn't often perch where I can easily photograph him. 












Great_Blue_Heron.JPG
Walking past the window (about 30 minutes ago), I saw this.  That's a Great Blue Heron (affectionately know around my house as "Big Blue").  He didn't stick around long.  The Red-Wings were harassing him because he's a predator.  But I did manage to get a closer image:

The "Eat Me!" Bird

Eat_me_bird.jpg
Kind of the exact opposite of the previous post.

Northern Cardinals, the males, anyway, leave me dumbfounded.  I don't understand how any prey-animal (other than poisonous ones) can be that red and not eaten to extinction.  Which led me to dubbing them, some years ago, the "Oh, please come here and eat me!" bird.  This was after I spotted one from 80 yards away.  Without my binoculars.  Recently, Nicole shortened it to "Eat Me! Bird."  That confused me because, initially, I thought she was saying EepyBird.  :-)

Mrs_Eat_Me_Bird.jpg
The females are subdued, at least by comparison.  Mrs. Eat Me! Bird does wear brilliant orange bill-color and red eyeliner, though.  Not to mention the red wing & tail feathers.

I noticed that Cardinals tend to appear in trios -- 1 male, & 2 females.  I don't know why, or even if I'm the only person who thinks this happens.  Maybe it's just me.  Maybe the Cardinals that live around here are messing with me.  ;-)

Camouflage, or "How Not to Be Seen"

Camo_Dove_1.jpg
I wrote, earlier, about moving the feeder stand from beside-the-driveway to the back yard.  Aside from worries about collisions, the location was farther from the house than I wanted, and probably farther from cover than the birds wanted.  I selected the new location, at least partially, to provide cover and "queueing."  I also decided (mostly from lazyness) to leave a brushpile behind it.  That has provided more interest than I expected it would.

For example, this image contains (at least) 2 birds.  One is fairly obvious -- the Tufted Titmouse on the feeder.  The other bird is not so obvious.


Camo_Dove_2.jpg
There it is.

Bear in mind, this bird is about the same size as a squirrel.  People legitimately shoot these as food.  Some of it's feathers are pink, and light blue.  But it's really good at pretending to be a rock.  This bird stayed in the same spot for hours.  Every time I glanced out the window, I checked.  Eventually, I let India out and that flushed all of the birds.


Camo_Dove_3.jpg
Same bird.  Even in close-up, it still blends really well with the surrounding brush and sunlight.  (Amazing, how much sunlight is at ground level.)  You can see some of the blue, around the base of its bill.

New Bird: Hairy Woodpecker

Downy.jpg
This is a male Downy Woodpecker.  How do you know?  He could be a Hairy Woodpecker.  The two species are notoriously difficult to distinguish.

The red patch at the back of his head tells you he's male.

The suet block is about 4" inches (I measured one), which tells you that this bird is about that size.  Too small for a Hairy.  He has a short, rather stubby bill, relative to the size of his head.  Too small for a Hairy.  If you look closely at the white feathers to the outside of his tail, you'll see black bars.  Hairys' tails have solid white feathers.

(Cool thing about this picture.  If you look at his bill, you can see his tongue.  Woodpecker tongues are specialized.  They're like little harpoons.  The bird will knock a hole in the wood, then tongue-spear the bug that he's hunting.)

If you've read any of the previous bird posts, you probably know that the Downy is not a new bird to me.  They've been coming to my feeder for years.  But I've never seen a Hairy Woodpecker.
Hairy.jpg
Until today, that is.

Last fall, I tired of the near-collisions with the feeder stand in the front yard (next to the driveway).  So I moved it to the back yard.  It's been a wonderful success.  (I think I saw an Eastern Bluebird out there, today.  We're well out of the Bluebird's Winter range, but the Great Backyard Bird Count (last weekend) lists them in the area.)

This is a male Hairy Woodpecker.  You can't see the red patch in this image, but it's there.  You can't estimate his size from this image, but I can attest that he's larger than the Downy.  You can see his longer, thicker bill, and the unbarred white feathers at the side of his tail.

Awesome.

Watching

Buffet.jpg
I refilled the feeder on the porch.  Peanuts, seed-mix, suet.














Watching.jpg
I'm not the only one happier for the reappearance of birds outside the front window.

Interestingly, to me, anyway -- is that the cats respond differently to different birds.  Nuthatches, for example, are generally ignored.  They flit to the feeder, take a peanut, and leave.  Woodpeckers are cause for chattering and riveted attention.  They sit and hammer -- obvious motion in a fixed location.

Amazon, Macmillan, Apple, and me

These are excerpted from an entry in Charles Stross's blog.  He's a Science Fiction author, has published through Macmillan, and, until very recently, referred readers to Amazon.  These passages are most relevant to what I want to say (emphasis his, in all cases):

Publishing is made out of pipes. Traditionally the supply chain ran: author -> publisher -> wholesaler -> bookstore -> consumer.

Then the internet came along, a communications medium the main effect of which is to disintermediate indirect relationships, for example by collapsing supply chains with lots of middle-men.

From the point of view of the public, to whom they sell, Amazon is a bookstore.

From the point of view of the publishers, from whom they buy, Amazon is a wholesaler.

From the point of view of Jeff Bezos' bank account, Amazon is the entire supply chain and should take that share of the cake that formerly went to both wholesalers and booksellers.
<break>

The agency model Apple proposed -- and that publishers like Macmillan enthusiastically endorse -- collapses the supply chain in a different direction, so it looks like: author -> publisher -> fixed-price distributor -> reader. In this model Amazon is shoved back into the box labelled 'fixed-price distributor' and get to take the retail cut only. Meanwhile: fewer supply chain links mean lower overheads and, ultimately, cheaper books without cutting into the authors or publishers profits.
    The point, in a nutshell, is that Amazon wants to keep the current supply chain.  Amazon does not want to go back to a world in which Amazon is only tail-end-Charlie, the book-seller.
    That's an untenable situation, because in an ebook market, there really isn't anything to "wholesale."  That part of the supply chain is unnecessary.  There's no reason to pay for it.  Obviously, Amazon's not going to shrug and say "Oh, well.  Guess we'll just have to get used to less money."  This fight isn't about what we pay to Amazon, it's about what Amazon pays to Macmillan.  Everybody understands that ebooks will cost less (both to produce, and at the retail counter).  Amazon & Macmillan are trying to decide who has to absorb the loss.
    If that's the case, then why is the fight ostensibly about the consumer price of an ebook?  The short answer is that Amazon uses that "extra" slice-of-the-pie to fund discounted prices for Kindle editions.  Amazon's strategy was to discount Kindle editions, acquiring the same sort of lock on ebooks that Amazon has on paper-books.  Then Apple came along with the iPad/iBookstore.  Apple is the kind of company that can sell enough devices to make iPad an "overnight" competitor to Kindle.  Or make the iBookstore a serious alternative to purchasing ebooks from Amazon.  No lock on the ebook market means Amazon can't dictate terms to Macmillan, et al.  No ability to dictate terms means Amazon eats part/all of the reduced profits in an ebook-future.
    So what does this mean for us, the consumers?  Not much.  Ebooks will be less-expensive than paper-books.  But right now, they account for 1% of book sales (according to the estimate I read today, anyway).  They are a niche, luxury market -- like limited editions.  As they become more mainstream, they'll conform to a pricing model that we all know: they'll be more-expensive when first published, and gradually decrease in price to some floor that reflects the minimum cost of availability.  The initial prices will be something like $15, not $10 (nor $25).  But, remember, Amazon offered that $10 price to serve a purpose.  There is no doubt in my mind that it would have increased, substantially, had Amazon captured control of the ebook market.

Oh, and one more thing, for anyone thinking Amazon doesn't do this sort of thing: http://www.thebookseller.com/news/59533-hachette-clashes-with-amazon.html.

iTrip Internals

| 2 Comments
This is a Griffin iTrip FM transmitter (older model).  I used it, daily, when I was driving 600 miles per week.  The gold thing is the mini-USB connector.  It came loose inside the case.  The transmitter still works, but there was no way to charge the iPod while using it.

USB_out.jpg

I built of pair of MintyBoost rechargers.  That involved soldering a USB connector to a circuit board.  That made me wonder if I could open the iTrip's case and repair it.

I couldn't get the case open.  Daniel suggested the case was glued, and a hair dryer would soften the glue.  He was right.  Hair dryer, a sharp knife, and patience were all it took.

Soldering will be more difficult than I expected, though.  The interior of the case is even tighter than I expected.  Plus, the mini-USB's attachment points are smaller than I expected.  If you look at the image, I need to solder the red-arrowed tabs onto the red-arrowed squares.  Should be fun!
