The Orion crew and service module stack for Artemis I was lifted out of the Final Assembly and Test (FAST) cell on Monday, November 11. The spacecraft has been stationed in the FAST cell since July 2019 for mating and closeout processing.
The service module and crew module were moved separately into the cell, stacked and connected together for the mission.
After lifting out of the cell, Orion will be attached to a tool called a verticator that rotates the stack from its vertical configuration to a horizontal configuration for transport to NASA’s Plum Brook Station in Sandusky, Ohio, USA, where it will undergo full environmental testing to certify the complete vehicle for flight.
Once the vehicle returns to NASA's Kennedy Space Centre it will return to the FAST cell for installation of final panels left off for environmental testing purposes and the service module’s four solar arrays.

Sjøhus, (sea houses, litterally translated) are industrial buildings from the times when boats were the only efficient way of transport. These cladded, timber frame buildings were used for all kinds of purposes connected to trade and fisheries on the Norwegian coast. The typical protruding part of the gable (vindehus) is protecting the hoist mechanism.

The Sweetening Deck Module for the Buzzard Oilfield is towed out of Hartlepool aboard the barge Giant 4. The module was built at Heerema Hartlepool Fabrication Yard 29th April 2010.
Voskhod 1 descent module, 1964
The three cosmonauts' couches inside Voskhod were only fitted with difficulty, making the crew crane their necks to see the instrument panels. With no space for a means of escape to be fitted, a retrorocket slowed the spacecraft as it returned to Earth, enabling the cosmnauts to remain on board for the entire mission.

Building consists of 4 modules.

Delivery of I2C modules. All these modules are intended to work together with the Fischertechnik TXT Controller. For the color sensor module there is already a software model available, the software for the other modules I am going to write. First I have to provide a small power supply for the 3V3 voltage.

Top view and underside of the layout module at testing stage. Modratec interlocked signal frame and Wire-In-Tube points drives are installed and operational. Semaphore signals are yet to be fitted, but their control cables are in place. Electrical wiring is set up for DC operation, with the option to convert to DCC - screw terminal blocks allowing easy reassignment of track droppers to the bus. Electromagnetic uncouplers and station lighting are also wired. Now, to test it...

... can easly be turned into a box and a lid
.. my design, as far as I know... but any reference will be welcome....
2 (1 for box, 1 for lid) square 15x15 cm. regular copy paper... I use 80gr. and 90gr. the second is suggested for the box
written instructions (more or less) in the kusudama cube writing.
Decoration made with paper left by cutting an A4 sheet in 2 squares... so you will just need 2 A4 paper for two duo color box.... and only 1 sheet for a single color box (obviously)... this box is very good for give aways in any occasion (espiacilly candies and confetti) and also as a toothfairy (or mouse depending on traditions) box..
I wish you a week full of colors!.... (north Italy in particular: wish you also a SUNNY week) :-))))

Double rotating module and built-in electronics.
This module is intended as an extension to the Fischertechnik building blocks. This is a compact unit with double rotation. Each stage has a built-in quadrature decoder and home point detection. Hall detectors are used for this. The big advantage of this hall AH3144E is that it works on a voltage from 4.5V to 24V and is therefore compatible with most hardware. The output is an open collector type. Each stage is powered by an XS motor 9V.
The upper axis has a pivoting block with 20 teeth. The gear profile is adapted to work with the worm gear of FT without much backlash. On the contours of this rotating block are small holes provided to apply a neodymium magnet D2x3mm. This magnet serves as a home point for calibration. On the worm shaft is a small disk encoder with 5 magnets. Through quadrature detection you get 20 pulses per revolution. The angle adjustment accuracy of the pivot block is therefore 1/400 or 0.9 degrees. The total angular rotation is slightly more than 180 degrees. The lower turntable has a gear with 44 teeth. It can rotate the full 360 degrees. The accuracy here is 1/880 = 0.41 degrees. The worm shaft also has an encoder disk with 5 magnets (20 pulses/rotation). The encoder disc is adapted to the worm so that it cannot slip on the shaft. All necessary .stl files are available here.
I tested all parts, mounted the hall detectors and measured the signals. The quadrature detection automatically possesses the correct 90 degree phase shift. You don't have to adjust anything. The XS motor is used with its standard reduction block and has about 140 revolutions/minute on the worm (2.35 rec/sec). An encoder pulse corresponds to about 21 msec. Your quadrature decoder must therefore be able to process the pulses within these 21 msec, or even better 15 msec because there is always a small deviation possible (phase shift is 90° +/- 20%).
On the upper rotation arm I mounted an original FT grip module. The intention is to replace this grip module with a more compact version with built-in electronics.
3D printer settings:
I always use PolyMaker polyMax PLA filament. This filament is much stronger than the normal PLA, even stronger than ABS. The printed pieces are very clean and the parts slide gently over each other. The tolerances are very good and very little finishing is required. For some parts you do need to use supports. Brim or Raft are not needed. I don't have a heated table but keep the printing plate under warm water for a while before printing. On my FlashForge Finder I use the Standard settings with a temperature of 210°.
