I've been tweaking my Skeinforge settings, but so far the ones I've found to work best are pretty close to the defaults that ship with ReplicatorG 0023 for the Thing-o-Matic
In 1946 the administration building of the former Finsbury Munition Factory was taken over by the Dept of Supply’s Defence Research Laboratories; later known as Materials Research Laboratories and various names until transferred to a Division of CSIRO, closed 2007, sold, opening as school 2021.
Finsbury Munition Factory was built 1940, one of several WWII munition factories in South Australia. Production of cartridge cases & shell fuses began Feb 1941; these were sent by rail to the Salisbury Explosives Factory for filling & assembly. Women over 21 were paid £2/7/6 per week and men £4 per week. There were 20 major buildings & many smaller on the 50 hectare site. A spur railway was built from Woodville station for the transport of goods & workers. (The former Finsbury station closed 1979 and the site is now occupied by a mosque.) After the war many buildings were taken over by various manufacturing industries. The site of the factory was known at first as Cheltenham (as it was near the Cheltenham racecourse), then Finsbury; name of suburb changed 1967 to Woodville North.
“Sixty men will be working early next week clearing and grubbing boxthorn and on other preliminary work on a big area of vacant land just north of the Cheltenham Racecourse. The Commonwealth factory for the manufacture of brass cartridge cases and fuses will be erected here for the Ministry of Munitions. . . A branch railway from the Port line near Woodville is expected to be laid to the Cheltenham works, which will include foundries and rolling mills for melting and fabricating the brass.” [The Mail 3 Aug 1940]
“plans for the new £1,000,000 rolling mill and cartridge factory at Cheltenham would be completed soon. This and the other plant at Salisbury would be distinct from the Hendon works. . . The whole of the machinery had first to be made in Australia and the rolling mill would have to be established before the making of cartridges could begin.”[Advertiser 9 Aug 1940]
“Ten houses were included in the area which the Commonwealth Government was acquiring for the munition works at Cheltenham Park. . . Occupants had received notice to vacate these premises, one of which was being demolished. The others would have to be removed. It was assumed that no house would be destroyed unnecessarily.” [News 20 Aug 1940
“Women would be wanted in almost unlimited numbers for work in the Cheltenham munitions works. . . they should register for work at the Port Adelaide Labor Exchange, next to the Courthouse, in Commercial road.” [Advertiser 3 Sep 1940]
“South Australian munitions works. . . The base wage rate will be £2/7/6 per week for women over 21, and there will be increases according to promotion. The base wage for men will be £4 per week, with margins according to classification. The main munition works for South Australia are a small arms factory at Hendon, rolling mills, and foundry at Cheltenham, and a filling factory at Salisbury, with annexes at Islington and work undertaken by private firms.” [The Mail 21 Sep 1940]
“Advanced progress is reported from Finsbury Park, where a Commonwealth gun ammunition factory is being established for the manufacture and repair of gun cartridge cases and fuses for shell. Many of the buildings have now been completed.” [Advertiser 1 Jan 1941]
“Department of Munitions. . . The numbers to be employed at the three Government factories were given as between 6,000 and 8,000 at the explosives and filling factory at Salisbury, about 4,000 at Finsbury Park, gun ammunition factory, and 2,000 at the small arms ammunition factory at Hendon. To this should be added several thousands more at the Islington tool room and shell annexes and at the various other munition annexes.” [Advertiser 3 Jan 1941]
“Commonwealth of Australia. Department of Munitions. A Senior Draughtsman is required for the Fuse and Cartridge Factory. Finsbury. . . This is a temporary position for at least the duration of the war.” [News 5 Mar 1941 advert]
“The gun ammunition factory at Finsbury for the production of brass components for gun ammunition, such as cartridge cases and fuses, was being completed, and production in certain sections was beginning. Further additions had been authorised.” [Advertiser 21 May 1941]
“South Australian workmen since last August have constructed solid, well-ventilated, and naturally lit buildings on a large proportion of the site of more than 100 acres. Laid down miles of smooth-surfaced bituminised roads, service pipes, and rail tracks. Installed huge quantities of machinery, all of which has been designed and manufactured in Australia — a good proportion in South Australia. Recruited as raw laborers, South Australians have shown a ready adaptation to many phases of the work, particularly in the foundry and rolling mill. Skilled tradesmen have brought their expert knowledge to this particular type of war work with refreshing results.” [News 18 Jul 1941]
“Mr. S. McGregor Reid. . . will take over offices at the Finsbury munitions works, from where he will control activities at other munition factories in the State.” [News 23 Jul 1941]
“A big program of alterations is in progress at the Woodville Railway Station, which will now become a junction of increasing importance. The Railways Commissioner (Mr. Anderson) said today that it was designed to provide the greater facilities needed in view of the new line to the Finsbury (or Cheltenham) Munition Works, and the generally heavier traffic. With a new track on the north side, the up platform would have a track on each side, making an island platform.” [News 7 Aug 1941]
“How Australian Industry Was Harnessed For War. . . Australia achieved an industrial miracle during the war in expanding munitions production from almost negligible proportions to an amazing variety of arms and equipment, costing hundreds of millions of pounds. It was an effort which raised Australia's industrial standards and status, and earned widespread gratitude and appreciation abroad. . . by the standards of modern warfare, the munitions industry in this country was virtually non-existent when war began.” [Advertiser 11 Aug 1945]
“employes at Finsbury munition factory will probably be kept employed until Christmas.” [Advertiser 12 Dec 1945]
“South Australia's first woman munition worker today said ‘good-bye’ to her job at Finsbury after a war effort which lasted almost six years. . . Miss Lorna Matthews. . . was a forewoman at Hendon before being transferred to Finsbury. . . She signed on at Hendon on April 15, 1940, after having trained in Melbourne for four months.” [News 6 Feb 1946]
“Vactric Electric Appliances, to be established at the former munitions plant at Finsbury, will have its first vacuum cleaners coming off the production line in three to four months.” [News 14 Mar 1946]
“The mammoth Finsbury factory is likely to become the headquarters of several new South Australian industries. Two companies have already decided to take over sections of the establishment, and other firms are negotiating with the Federal Government. Vactric Electrical Industries — one of the two firms which have already decided to establish their manufacturing plants at Finsbury — has taken over the big No. 2 fuse factory near the Torrens road entrance, and a boiler house. Preparatory work for beginning production has begun. Manufactures will be mainly vacuum cleaners and fractional horsepower motors. The other company — Firestone Rubber Co.— will occupy the main buildings in the stores section at Finsbury North, facing the Main Junction road.” [Advertiser 6 Apr 1946]
“Although it had been operating only since March, the Munitions Supply Laboratory at Finsbury had already carried out work for 16 of the State's largest industrial concerns. . . it was proposed to increase the present staff of 18 to about 50 experts and assistants, skilled in scientific and technological matters, particularly in the field of secondary metallurgy and industrial chemistry. . . the facilities to be provided would include complete equipment for carrying out metallurgical investigations. X-ray and radium examination of castings, weldments and bearings, pyrometric calibration and certification, and a general technical information service. Costing about £3,500 an X-ray plant, which would be used for detecting flaws in metal, would arrive probably next week. The laboratory would take over from the Adelaide University the calibration, certification, and checking of industrial pyrometric installation throughout South Australia. The University had been carrying out the service on behalf of the Mnnitions Supply laboratories since 1940.” [Advertiser 13 Jun 1947]
“Industry Takes Over At Finsbury. All available space at the big war-born munitions factories in South Australia has now been allotted to new or expanding secondary industries, or is held under option by interests which plan to come here. Radios, refrigerators, car parts and accessories, baths, sinks, vacuum cleaners, a range of electrical equipment and scores of other consumer goods are flowing from the sprawling saw-toothed buildings which were built to make the materials of war.” [Advertiser 6 Dec 1947]
“chief officer of the Commonwealth Defence Laboratory at Finsbury (Mr. J. S. McNeil)” [News 21 Oct 1949]
“A mobile X-ray camera, the only one of its kind in the State, and one of three in the British Empire, was used here for the first time yesterday in efforts to trace suspected internal cracks in a steam boiler at the Glenelg Knitting Mills. The machine, owned and operated by Defence Research Laboratories, Finsbury, is operated by remote control, so that the operator will not be affected by X-ray radiation.” [Advertiser 28 Apr 1950]

My Zorki 4K camera and its Jupiter-8 1:2 f=50 mm normal lens clearly needed a calibration of its range finder. It is a very easy task for the infinite, acting on a small adjustment screw located at the front, left to the finder window. This film is a test of the focusing capability now much more efficient. There still a tiny shift that I will try to optimize soon following the known protocols (tomtiger.home.xs4all.nl/zenrep/calibration.html)
The camera was loaded with a CineStill Double XX (cine film Eastman 5222) exposed for 200 ISO using a Minolta Autometer III lightmeter fitted with a 10° viewfinder for selective measuring privileging the shadows. After exposure the film was processed using Tetenal Ultrafin developer at dilution 1+20 for 12 min and 20°C.

About the camera :
This camera was manufactured in 1977 by KMZ company ( Красногорский механический завод, Krasnogorskiy Mechanicheskiy Zavod) located in the Moscow region. KMZ also manufactured the ZENIT SLR's among many other productions. Zorki 4K was produced between 1972 to 1978 and the previous Zorki models were inspired by the Leica II since 1949. This model 'Made in USSR" is branded in roman characters, intentionally for exportation. Other Zorki 4K were also branded in Cyrillic as "Зоркий". Zorki 4K was sold basically either with this Jupiter-8 lens 1:2 f=50mm or the Industar lens1:3.5 f=50mm. The Jupiter-8 is a Sonnar Zeiss optical formula and fits to the Zorki body using the screwing M39 Leica mount.
Its was sold to me in August 2022 from Austria with its original ever-ready leather bag, a front lens cap and a small shade hood accessory Minolta D42KA. The shade hood and filter of my Focaflex also fit to the Jupiter lens (Leica standard 42 mm filter)
Kamal Sarabandi holds radar calibration targets at the “anechoic chamber” in his lab. These are targets with know radar cross section values.
The anechoic chamber is used to characterize antennas and measure radar cross section of different targets. This chamber is designed to simulate a free-space environment where signals radiated from sources within are all absorbed by the foam materials attached to the walls.
Kamal Sarabandi (Persian: کمال سرابندی) is an Iranian-American scientist and the Fawwaz T. Ulaby Distinguished University Professor of EECS and the Rufus S. Teesdale endowed Professor of Engineering at the University of Michigan, where he teaches and conducts research on the science and technology of microwave and millimeter wave radar remote sensing, wireless technology, electromagnetic wave propagation and scattering, metamaterials, antenna miniaturization, and nano antennas.
Professor Kamal Sarabandi has had a distinguished and exemplary career as an educator and entrepreneur, focusing on the field of applied electromagnetic and microwave remote sensing. He is known for his seminal contributions to the science and technology of radar remote sensing for imaging the Earth's surface. His pioneering work on design of polarimetric radars, development of sophisticated electromagnetic scattering models for natural targets and their inverse solutions for monitoring vegetation, soil moisture, and snow has had important implications today for better understanding of processes that lead to global warming. He was the first to establish the connections between the incoherent and coherent domains of radar polarimetry.[1] Sarabandi served as Director of the Michigan Radiation Laboratory in the Department of Electrical Engineering and Computer Science at the University of Michigan (2000-2021).
Kamal Sarabandi holds a number of patents and is a founder/co-founder of several companies.

Aerial Survey program Calibration and Conformity field training. L-R: Aleksandar Dozic (WDNR), Ben Smith (USFS), Glenn Kohler (WDNR), Amy Ramsey (WDNR) and Melissa Fischer (WDNR). Near Ellensburg, Washington.
From Karen Ripley: "The aerial observers from Washington, Oregon and the newest hire in the fold Jackie Pope, who will be working in California, met in Ellensburg, Washington for “Calibration and Conformity” training. It was a great opportunity to review new policies, contracting, safety and logistics for the 2018 season, as well as practice the techniques for recording damage with DMSM tablet units. California used DMSM extensively in 2017. Oregon and Washington used this software for the Swiss Needle Cast survey in 2018. Increasing the number of observers who are doing the surveys and moving from a single agent (SNC) to many agents, points and polygons, defoliation and mortality, across diverse terrain made the need to discuss techniques and approaches to recording damage and hone skills particularly critical for 2018. The sessions included flying and mapping along a pre-planned route over several forest types (with associated damage present) and then comparing/discussing the resulting maps and data during a subsequent field trip to those sites. Glenn Kohler and Justin Hof, with help from Darci Dickinson and Connie Mehmel, located and measured the featured field sites, so deserve enthusiastic appreciation for their support towards excellent aerial survey data acquisition."

Two of my recent [debayered]master flat and master dark files. They have only been modified by auto-stretching the histograms in PixInsight and saved as JPG.
First test program to control and adjust already 3 trampolines. The settings to go via 2 trampolines to an output funnel with the balls is not easy. With the right adjustments I managed to get most of the shots correct. Now I can make the position optimization of the funnels. Especially driving sharp corners in the right direction is not easy. Once the values are determined I can use them in a final program. Setting the turn table and trampoline angles is very precise. The calibration is also perfect. Because of the quadrature decoders there are no cumulative position errors.
Eerste test programma om reeds 3 trampolines te sturen en af te regelen. De instellingen om via 2 trampolines naar een output funnel te gaan met de ballen is niet eenvoudig. Mits juiste afstelling lukt het toch om de meeste shots goed over te brengen. Nu kan ik de positie optimalisatie van de funnels maken. Vooral scherpe hoeken in de juiste richting sturen is niet eenvoudig. Eens de waarden bepaald kan ik dit in een eind programma overnemen. Het instellen van de draai tafel en de trampoline hoeken gaat heel precies. De calibratie verloopt ook perfect. Door de quadrature decoders zijn er geen cumulerende positie fouten

Plustek OpticFilm 120 Pro Scanner
Screenshot during use of Plustek Lens Calibration Tool.
This is a separate program from Plustek which is NOT integrated in the Silverfast scanning software.
As can be seen the 35mm film strip holder is automatically recognized.
Further more one has to choose :
- between Positive or Negative
- Place of the target in the holder
- Max.Res(olution) Yes/No . Standard resolution is 2650dpi. Max. resolution is 5300dpi
In this case I used an USAF 1951 high resolution film as a target.
Here’s my Turnigy 150W Accucell 8150 charger. After watching a YouTube video I was inspired to test and calibrate the voltage readings on it. Holding down “-Dec” and “Start/Enter” on powering the device enters this mode. This seems to be common to many four button chargers.
What become apparent (even before I checked again with the Fluke 87 V meter on to it) was how out the charger was. I had to plus 20 increments to get it close to matching the multimeter. That’s the max for this charger and it’s still a little out. This test was done with a 3-cell lipo and it seems to be further out with batteries with a lower voltage. I was disappointed.

pro secret: Calibrate Your Display
Show the World Your True Colors
I can work confidently on a properly color-calibrated screen and can assert greater control over the color fidelity of my digital photo process. Photos can be reliably assessed and adjusted on a properly calibrated display, enabling true-to-life reproduction of my photos.
Why Calibrate Your Display ?
- Displays render the same image differently: Calibration tunes your display to a reference standard and brings color consistency across desktop, laptop, multiple displays, iPad and iPhone.
- Displays change over time: Recalibration returns it to reference state for brightness and color
- Prints often do not match display: Display calibration provides a base for better print matching
- Wide gamut displays may be oversaturated: Without calibration even wide-gamut displays may be inaccurate.
- Highlight and shadow details may be inaccurate: Control of brightness, white point and tone response with calibration.
- Image colors are not true to life: After calibration, images can be viewed and edited with confidence
you can buy it from Adorama or Amazon
I buy all my photo gear from Adorama, they are the best in the business, they have international shipping, superb costumer service and best prices, some times i order from Amazon too, they sell everything you can imagine, they have outstanding costumer service and best prices.
Title: Technician at work, Optics Calibration Department, Varian Techtron, 679 Springvale Road, Mulgrave
Author / Creator: Sievers, Wolfgang, 1913-2007 photographer.
Date: 1974
Varian Techtron was the result of a merger between the Australian company Techtron and the American firm Varian Associates in 1967. The Springvale Road site (then in Springvale North, but now in Mulgrave) was established by Techtron and is still in use, but now as Agilent Technologies (which acquired Varian in 2009). Techtron Appliances was established in 1938 and it and its successor companies have produced a variety of electronic and analytic equipment for industry and scientific research, notably including Atomic Absorption Spectrophotometers (AAS) to CSIRO specifications.

This equipment was used for the re-calibration of exposure meters.
Probably factory-made equipment for the external serviceworkshops.
Quite modern because there are already LEDs used. My guess is somewhere in the nineteen-seventies or -eighties.
Having a 50mm f/1.8 lens with a noticable front focus is a pain in the back side - paying 60 euros for a calibration target is too expensive for a Dutchman. So this is my home made lens calibration target. It works, but the calibration factor for my 50 mm f/1.8 had to be adjusted to the limit of my EOS 7D.
My new level was not quite on the level;
so I decided to perform an exploratory bubblectomy.
My trusty little Swiss Army knife easily popped out one of the plugs at the end of the main vial.
As I had hoped there was a screw underneath.
The second plug was much more difficult to remove and was nearly destroyed in the process.
Apparently the factory used glyptal, lock-tight or some similar substance to lock the screws in place and some of it locked the second plug in place as well.
I removed the screws to view their fine threads for precise adjustments.
I removed the vial and found the final item I hoped for; namely a pair of rubber pads.
(If the pads had not been there, I would have had to make my own out of an old inner-tube.)
It will now be a simple matter to reassemble the level and then to re-calibrate it; by adjusting the two screws to compress the two rubber pads as required to make the bubble center when the level is level.
This image shows the beginning of the calibration of the measuring device during Vickers hardness test. In order to check that the measuring device is calibrated an impression on a standard test block is made. It then checked that the measured result lies within the acceptance range of the block.
