HO Scale - Free-Mo module built of two sections, representing the town of Stephentown, NY on the Rutland Railroad's Chatham "Corkscrew" Division.
A - Sheffield Milk Creamery (active 1914 - 1950)
B - E.B. Estes & Sons Storehouse (built before 1908)
C - E.R. Potter Feed Mill (built early 1900s)
D - Stephentown Depot Station (active 1870 to 1953, demolished 2011)
E - Vanderbilt Hotel (built 1871, possibly located on other side of the tracks, still researching. Current building at this location is listed as once being a "tavern", now a residential building.
F - E.R. Potter Lumber Shed (built early 1900s)
G - E.R. Potter Cole Bin (build early 1900s)
Other industries could include cattle and automobiles. At one time a cattle unloading station was located here, and in the 1930s, a Chevrolet dealership across the street from the team track unloaded cars via ramp at this location. Still researching exact locations of structures.
Technicians at the Airbus facility in Bremen, Germany prepare the European Service Module for shipment to Kennedy Space Center. The service module will depart Germany on November 5, 2018 and will arrive in the U.S. on November 6.
For the first time, NASA will use a European-built system as a critical element to power an American spacecraft, extending the international cooperation of the International Space Station into deep space. The European Service Module is a unique collaboration across space agencies and industry including ESA’s prime contractor, Airbus, and 10 European countries. The completion of service module work in Europe and shipment to Kennedy signifies a major milestone toward NASA’s human deep space exploration missions to the Moon and beyond.

Guidance for LED flash module. 2 rails 250 mm length are used to move the led-flash module into the optimal position. Rails are silver steel axes 8 mm x 250mm. The holder contains internal nylon guides. As a result, the movement is smooth and vibration-free. There are two of these units used, one on each side. Later comes another detail how the container holding the LEDs. They must be able to be removed quickly. Hence this special construction.
I spent some hours trying to make two xbee wireless modules
communicate. These will be part of our new flaming doorbell. The
trouble was with my transistor setup for the relay. The modules were
communicating, but the logic was backwards and each time I hit a
button the relay would turn off. I need the opposite behavior
otherwise their would be a 20' flame at all time at our place. I
finally gave up on trying to convince the xbee modules to behave
rationally and just switched to a PNP transistor for the relay.
The configuration for both xbee modules is straight forward (thanks
ladyada for documenting this):
Remote - TX setup (attached to doorbell input button)
- D0 - DIO Configuration - (3 - DI) [data in]
- IC - Dio Change Detect - (FF)
- Set sample rate to 0 (unless you want synchronous updates)
Base - RX setup
- DO - DIO Configuration - (4 DO) [data out low]
- Under I/O Line Passing set "Input Addresses" to 0xFFFF (allow any
radios)
- Set IU - I/O Output enable to Disabled
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.

PCB for Cree led flash module. Inside the opening for the Mitutoyo 10X lens. The 12 power leds are not solderd but connected via 24 x M2 brass screws which press on the led contacts. I can even modify LED types with the same module. Soon there will be another picture where the LEDs are mounted.
The 12 LEDs are divided into 6 groups. Each time there are two LEDs connected together on the PCB. LEDs shine through the 12 holes of 8mm diameter each. Each group can be controlled separately. The direction and amount of light may be a result set.

High-power color led module. Although a simple print it is still difficult to solder for a man of 71 years old like me! And these LEDs are not cheap, 20 euros each. Each channel of the four LEDs are connected in series. The leds are red,green,bleu and white. This is the backlight which I can adjust the color and brightness. The next print to solder is the driver for this color led module.
This color module is used as background lighting. There are 4 channels one for each color. The max current is 700 mA/channel when the 4 elco's 4700uF each are charge to the max 19V. Thereafter, the current is kept lower, without limitation in time.
Voltage and power per channel with 4 leds in serie:
Red..... : 9.2V peak power = 6.44W
green : 14.8V peak power = 11.84W
Blue... : 14.0V peak power = 9.80W
White : 14.0V peak power = 9.80W
Total peak power ............... 37.88W

For the driver print see:
6 channel power-led driver module. Each channel drive two high power LEDs 9V. The capacitors provide a high peak current for a certain period of time. After this time, a continued nominal power is used. The peak current is set per channel by a potentiometer. This is 19V- 700 mA per channel. Each channel is driven for a certain time. The light distribution and brightness can be controlled.

Update 14 nov 2014:
Some R values changes for optimal results. PCB is now tested. The total peak power is 80W for 25 ms.
Lockheed Martin technicians at NASA's Michoud Assembly Facility in New Orleans, Louisiana, complete the final weld on the pressure vessel of the Orion crew module for Exploration Mission-2, the first flight of Orion with astronauts which will carry them farther into the solar system than ever before.
I built this piece based on these instructions. The units are easy enough to make but the construction was a little more challenging for me. I found it easier to view it from the inside and then it built up quickly.

Six lunar test articles (LTAs) formed the backbone of Grumman's ground test program of the Apollo lunar module. Bethpage shipped LTA-2 to Huntsville for vibration testing to see if it could withstand launch pressures, and LTA-10 to Tulsa, to check its fit in the adapter. LTA-1 was a "house" spacecraft, used to iron out problems during fabrication, assembly, and checkout. Three more LTAs were under construction: LTA-8 for thermal-vacuum testing in Houston and LTAs 3 and 5 for combined structural shakings, vibrations, and engine firings.
LTA-1 resides at the Cradle of Aviation Museum, Long Island, NY.
