“The Companion” By Bulova Model-206 Portable AM Tube Radio

Image by Andrew Pilling
This Teal Blue &quotCompanion&quot by Bulova transportable AM radio, model 206 was a good (curbside) uncover. The physique was in fairly very good condition, so I opened the back of the radio and noticed that the two (ancient) D batteries have been corroded and brought on mild staining with no apparent harm to the interior. I also noticed that one particular of the four vacuum tubes, a (1U5) tube was MIA. Right after a appear-see in the tube bible which informed me that there were comparable tubes with different pin allocations but, there weren’t any identical substitution tubes. I was in a position to locate and replace the (1u5) vacuum tube. Subsequent without having performing any type of tests, I rolled the dice and turned it on. &quotEUREKA&quot as soon as again an additional roadside discover started up and worked, then the inevitably dreaded (par for the course) obligatorily telltale HUM of all HUMS became really apparent. So I turned on and warmed up my favorite and trustworthy VTVM-voltmeter (the Hewlett Packard 410B). With voltmeter probes in hands, I went appropriate to the usual suspect, The infamous electrolytic filter capacitor. It was shot so I left it in place, being that they are a Royal discomfort on my patience to desolder, take away, disassemble and gut out the filter caps fragile cylindrical cardboard housing to be stuffed with three new electrolytic capacitors, then reassemble and solder the component back into location, So I performed a bypass using 3 new e-caps, carefully tucking them inside of the tightly cramped beneath carriage of the chassis. I turned it on and the HUM was no longer noticeable, &quotVOILA&quot it functions. This Bulova &quotCompanion&quot portable radio will be a nice addition to my collection.

Google’s Master Program

The Master Strategy has several paths. Some turn to the dark side of Skynet, and most lead to user happiness…

Laboratorium Solaris: back into action

Image by Sergei Golyshev (reloaded 🙂
06.01.2015, 11:45 (UT+3), clear cold winter day, -17&degC, the Sun is eight&deg above horizont and looks like as if being observed by way of the flowing water.

The image looks satifactory at 500 pix size.

WARNING! Sun is hazardous, use suitable filters for observing and imaging!

Canon 60Da by way of BP Hyperion Zoom eight-24 mm eyepiece on Coronado PST more than photo-tripod.
Aperture 40 mm
Native focal length 400 mm
Projection focal length 24 mm
Television = 1/200 s
Av ~f/20
ISO 200
Capturing application: NA
Exposures: 7 out of 28 (poor seeing, extremely poor). RAW pictures were converted into monochrome and adjusted for some more contrast in Canon DPP and exported as 16 bit TIFF. Each and every frame was calibrated with master dark made of median of 10 dark frames and master bias produced in the same way from 20 offset frames.
Master calibration frames, substraction and pre-alignment had been made in ImageJ.
Frames were analysed and stacked in Autostakkert2! 2.3.021alpha (specially for stacking H&alpha photos, ha-ha :), resulting image was subjected to Richardson-Lucy deconvolution (Cauchy type PSF, 3,six units, 7 iterations) and was sent to Photoshop for &quotcreative&quot clean-up, downsampling and coloration.

Note: this is quick exposure image, so the red channel dominates, which is right. But I have followed the effortless way of turning raw images into monochrome in raw converter. This algorithm behaves like as if it makes a sum of all channels and somehow weights the contribution of red and blue in relation to green. But green channel includes largely its personal noise and other junk elements. Perhaps it really is greater to not to do this, but extract red from color image and then down-sample it ,5x to smooth de-Baeyring artifacts? Hmm…

Some cool machining supplier pictures:

In the 1970s, the bigger suppliers of motorcycles to the Post Office progressively gave way to other tends to make such as Puch, Honda and Kawasaki.

Puch mopeds had been employed in modest numbers for each Telegram and letter delivery function. Its tiny size produced it most suitable for low volume deliveries in towns and rural places.

The machine on display was utilised at the Northern District Office, London (based at Finsbury Park).

AGA Operate

Image by Melinda Stuart
My wonderful AGA cooker got a after-a-decade going more than by Walter Sands, AGA-man extraordinaire, who specializes in developing these amazing stoves in place. Following 1 purchases an AGA, it is assembled in its final location by a specialist, such as Walter. Built of enameled cast iron, they weigh about 1,000 lbs., so you do not move them around with out disassembly. This is hardly ever completed, but sometimes owners choose to take them along to a new residence. 1 does get quite attached to them!

I do not have enough space here to explain and speak about our relationship with this object in our lives. It is so significantly more than &quotan appliance&quot.
Those of you who know me, know that I typically let Wikipedia do my explaining for me–
they do it so nicely! So:
en.wikipedia.org/wiki/AGA_cooker

That offers you &quothow they perform&quot.
But the very best element is how critical they turn out to be to your life! Their warm heat (not also hot) is a living presence. When ours was off for two days–the fault of the fuel supplier who inexplicably forgot to fill our tank!–we missed it quite much–especially as the period coincided with a couple of winter’s coldest days.

The fuel difficulty caused failure of the thermocouple which then required replacing, and Walter, the AGA-man, took the chance to give the cooker a complete appear-over, which it hadn’t had in a decade. He declared it in surprisingly excellent condition.

There are no moving parts in an AGA (and no microchips, to my expertise!!!) except the burner you see in Walter’s hands–and that doesn’t move much. Practically nothing considerably to break and the thermocouple is pretty low-cost to replace (now used to be ). The ovens are self-cleaning. Only the exterior requirements wiping down with a cloth, and about every six months I give it a polish, as shown in the upper two views.

These machines are pricey (but ours, purchased in 1998, price half the present cost)–and they a lot more than spend for themselves in functionality. I have no microwave, no toaster, no slow-cooker or such. Plus they dry (and even iron!) garments–and 100 other things (actually). And feel of all the bread it bakes perfectly? They turn out to be heirlooms–and employed ones, if 1 can be located, are still expensive. These never get trucked to the junk metal man!

Yes, we love our AGA.

PS: In reading the Wikipedia entry above, I see that their reasonably high usage of fossil fuels is called to account and that when compared to an &quotordinary gas stove&quot they don’t stack up as well nicely. But, we stand by the several intangible side rewards experienced, some of which I mention above, and the ambient space heating which is of considerable worth three quarters of the year. We do not turn ours off in summer, but I preserve threatening to do so. (Where would I bake my bread?)

The Wiki report states that sales have dropped tremendously in recent years, but the last date talked about is 2009. I’m told that installations for 2013, at least in the States, have picked up considerably. Possibly this all has to do with the common recession we’ve knowledgeable and are now beginning (they inform us) to come out of. The AGA is here for the extended haul!
