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.

The Moon Module Repair Rover is ready to fix any damage to any module anywhere on the moon! See this remote-control MOC in action here!
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...

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.

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°.

This is an actual lunar module, one of 12 built for Project Apollo. It was meant to be used in low Earth orbit to test the techniques of separation, rendezvous, and docking with the command and service module. The second of two such test vehicles, its mission was cancelled because of the complete success of the first flight.
The lunar module had two stages. The descent (lower) stage was equipped with a rocket motor to slow the rate of descent to the lunar surface. It contained exploration equipment and remained on the Moon when the astronauts left. The ascent (upper) stage contained the crew compartment and a rocket motor to return the astronauts to the orbiting command module. After the crew entered the command module for the trip back to Earth, the lunar module was released and eventually crashed into the Moon.
National Air and Space Museum
The National Air and Space Museum of the Smithsonian Institution holds the largest collection of historic aircraft and spacecraft in the world in 14,970.9 m2 of exhibition floor space. It was established in 1946, as the National Air Museum, and opened its main building in 1976. Located in Washington, D.C., United States, it is a center for research into the history and science of aviation and spaceflight, as well as planetary science and terrestrial geology and geophysics. Almost all space and aircraft on display are originals or backups to the originals.
I matched the LEGO green and painted the modules. This made a huge difference in appearance when they were all laid out. The painted edge blended in really well with the green baseplates.
Description:
We design, develop, manufacture and sell variety of monocrystalline modules ranging from 5 W to 290 W in power output, built to general specifications for use in a wide range of on-grid and off-grid residential, commercial, industrial and other solar power generation systems.
To assemble solar modules, we interconnect multiple solar cells by taping and stringing the cells into a desired electrical configuration. The interconnected cells are laid out, laminated in a vacuum, cured by heating and then packaged in a protective light-weight aluminum frame. Once sealed, our solar modules become weatherproofed and are able to withstand high levels of ultraviolet radiation and moisture.
Our 220W series modules conform to IEC61215 and IEC61730 electrical and quality standards. With continuous commitment to research and design, our engineers work every day to improve quality, efficiency and reliability of our modules. Manufactured under ISO9001 and ISO14000 certified conditions, our modules are engineered to withstand extreme temperatures and harsh weather conditions.
