I've been wanting to try a standing workstation for quite a while now and I finally took the plunge a few weeks ago. Like the author of this post on Web Worker Daily, I didn't want to spend a lot of money setting it up. After experimenting to find just the right height, I discovered that I could obtain that height simply by using an empty cardboard box from our food delivery service (I even get a new box each week with my fruits & veggies delivery).
The best thing about this compact setup in my kitchen is that at the end of each day I tear it down and pack it up, which takes all of 5 minutes and puts a firm cap on the number of hours that I end up working.
Engineering of the compact fluorescent light bulbs
Canadian federal government has adopted a national standard for lighting efficiency that came into effect in 2014. Most, if not all conventional, incandescent light bulbs do not meet the required performance level. The objective was to make sure...
Wearing a dapper suit of Charcoal Pearl Wrap, this splendid Compact Nesting Kit features a super-sturdy DW tom arm ready to hold everything together! 8x10, 9x13, 14x16, 18x20, 5½x14; plied maple; Charcoal Pearl Wrap.
My exemplar of the RINGFOTO rallye 701, with some heavy dents. It is a renamed Cosina compact 35E, and like many cameras of its time it features a combination of a rangefinder, a programmed shutter and a flash-matic. The lens is a Cosinon 2.7/38 mm, the shutter is made by Copal. Because of the programmed shutter every f-stop has its dedicated shutter speed and these pairs are shown in the viewfinder, which is a bit unusual. The range is from (1/30-2.7) to (1/650-16).
Ringfoto is a union of camera shops founded in Germany 1965. Meanwhile it's a huge European enterprise, it could take over Photo Porst, a great competitor, and it even is the owner of Voigtländer.
BTW, Porst sold the same camera as Porst 135S, and a cheaper version Porst 135C without rangefinder and selftimer.
This shot was taken with a Carl Zeiss Jena Pancolar 1.8/80 at f/1.8 with a 12 mm spacer ring, attached on a camera with APS-C sensor. No sharpening or CA-correction were done.

Some background:
The Kawasaki Ki-78 started its life as KEN III (Kensan III - research III) at the Aeronautical Research Institute and built at Kawasaki Kokuki Kogyo K.K. (川崎航空工機業株式会社 - Kawasaki Aircraft Industries).The plane was originally planned as a high speed research aircraft and designed to investigate laminar profile wings with high wing loadings.
The KEN III was a very small and compact aircraft, reduced to a minimum. It featured a streamlined, minimum cross-section fuselage, together with a cockpit canopy that was more deicated to speed than good pilot sight. An all-metal construction was used in combination with a small thin wing with a laminar flow profile and a sharp leading edge.
The aircraft was fitted with a licence-built Daimler-Benz DB 601A engine. For short duration power boost methanol/water injection was used, and cooling was improved by a 45 kW (60 hp) turbine driven cooling fan for the radiators, which were placed on both fuselage flanks, right behind the cockpit.
Early in 1938 a high-speed research program was started at the Aeronautical Research Institute of the University of Tokyo, with the attempt to break the World Absolute speed record.
By the outbreak of the war, the whole KEN III project was taken over by the Imperial Japanese Army who gave it the military type designation Ki-78. Kawasaki received the order to build two prototypes of the Ki-78, construction of which was started in September 1941.
The first was completed more than a year later and was flown for the first time on 26 December 1942, but it did not live up to the high expectations concerning top speed - instead of the projected 850km/h the Ki-78 never exceeded 700 km/h (435 mph) under ideal circumstances. Handling was also hazardous. The second Ki-78 was therefore never completed.
A feasibility study to improve the KI-78 flight performance and make it suitable as a high speed fighter showed that extensive airframe modifications were needed. Consequently the World Absolute speed record project was officially terminated and the unfinished second prototype as well as a third airframe modified into what would soon become the Ki-78 Kai.
The Ki-78 Kai was an almost new design. While it kept the KEN III's sleek lines, including the DB 601 and the fan-augmented radiator arrangement, the wings had been considerably enlarged (by ~4m²/171ft²) and the fuselage stretched - primarily in order to improve agility at medium altitude: true to IJA tradition.
As a consequence, armor and other protective measures were reduced to a minimum, while armament consisted of a single 20mm cannon, firing through the propeller hub, plus two 12.7mm machine guns in the wings, outside of the propeller disc. Still, the Ki-78 Kai was about 200kg heavier than the KEN III.
This machine was quickly ushered into production and reached front line units in late 1943, though. Upon the first clashes with Allied fighters the poor survivability became obvious, despite the type's speed and climbing rate potential. This led, after only 50 machines, to the Ki-78 Kai-Otsu (or Kai-II/Improved, Type 2), which received additional armor for cockpit and engine, and a revised armament of two 20mm Ho-5 cannons in the wing. The engine-mounted gun was deleted in order to save weight again, but the modified aircraft weighed again about net 50kg more, but still achieved a staggering 675 km/h in level flight.
This revised version arrived in the Pacific theatre around May 1944, where it replaced the obsolete (but still popular) Ki-27. While the type's performance was on par with the modern Alied fighters of the time, many aircraft were lost due to poor tactics and unexperienced pilots. Furthermore, the Ki-78 Kai was not designed to take much damage, so that it was unpopular, even though in the hands of experienced pilots it was a serious opponent.
Neverthless, until April 1945 only 320 Ki-78 Kai were produced and production was stopped in order to concentrate on radial-powered engines and fighters with a better high altitude performance.

The kit and its assembly:
This is a conversion of AZ Model’s Ki-78, which is available in two double sets – the aircraft is so tiny that they put two kits into the box! There had been plans to convert the record breaker into a fast fighter – and my whif is more or less an interpretation of this idea.
Starting point was that the whole aircraft had to be enlarged, in order to put a decent fuel amount and some armament somewhere. First step was increased span/wing area – I found a pair of outer P-38 wings that had a very good size and shape for the task, and the lower side was still “clean” so that I could cut out new openings for the landing gear, using the original parts.
Once the wings were in place, I added a 5mm plug in front of the fin, so that span/length ratio could be kept – the only place due to the flanks-mounted radiators. I kept the fin OOB, because it was big enough, but I implanted bigger horizontal stabilizers - these come from a Matchbox Brewster Buffalo but were considerably reduced in depth, trying to match the main wings's shape.
Air scoops for the oil cooler were added under the front fuselage, and steel needles were implanted as wing cannons.
Painting and markings:
This one is based on a real aircraft, a Ki-84 I found in literature. It was painted in a rather light khaki drab tone from above, with greenish-grey undersides, plus white markings on wing and fin tips.
The upper basic tone is FS 34087 from Modelmaster, applied over a basic coat of acrylic Aluminum (Revell), so that the metal would shine though and even appear chipped in some areas – some wet sanding enhanced the effect, and dry painting with lighter colors like Humbrol 83 (Ochre) emphasized the worn look. An area behind the cockpit received only very little green cover, the propeller spinner was painted in a mix of Olive Drab and Humbrol 95 (Concrete).
For the underside I used Humbrol 90, actually Sky Type ‘S’, but it comes very close to IJA grey and makes a nice contrast to the brownish upper side. Here, too, the paint was applied over an Aluminum primer coat.
The white markings were painted with very light grey; the cockpit interior was painted in a IJA "Cockpit Green", a tome very similar to RLM02. I used Modelmaster's "Faded Olive Drab" as basic tone, plus some dry painting with light grey. The landing gear was kept in aluminum.
Decals were puzzled together from various sources and sheets, e. g. from a Ki-27 aftermarket sheet and a squadron markings set.

Top of the line 1976.
It was the first camera to feature both shutter priority and aperture priority automatic exposure modes.
XD-7 brochure:
"A definitive statement of the camera manufacturer's art. Minolta was the first to offer multi-mode exposure 35mm SLR camera: Minolta XD-7. The XD-7 is a completely professional camera, with an advanced "total information" viewfinder. Its sophisticated electronics combined with its lightweight, compact design make it on of the fastest and easiest SLR's ever built. In short, it's in a class by itself."
mir.com.my says:
"...the XD-7/11 settled the debate over aperture-preferred vs. shutter-speed-preferred automation because it was a both - it gives you a choice between either mode..."
"...it was the Minolta XD-7 that has kicked started the full and sophisticated automation in camera design in 1976..."

Yeah. A "compact" (it's not quite pocketable) with a fast f/1.9 lens and a red Canon "L" lens ring!
Well, it's a big chunk of plastic. Too bad you can't use any functions manually, i would have liked that in combination with this lens.
Anyhow. I think i'll put a roll through it, must say i'm quite curious!
