Meteor Crater is today a popular tourist attraction privately owned by the Barringer family, with an admission fee charged to see the crater. The Meteor Crater Visitor Center on the north rim features interactive exhibits and displays about meteorites and asteroids, space, the solar system and comets. It features the American Astronaut Wall of Fame, and such artifacts on display as an Apollo boilerplate command module (BP-29), a 1,406 pound meteorite found in the area, and meteorite specimens from Meteor Crater that can be touched. Formerly known as the Museum of Astrogeology, the Visitor Center includes a movie theater, a gift shop, and observation areas with views inside the rim of the crater. Guided tours of the rim are offered daily.
The crater continues to be a focus for scientific research.
Meteor Crater is a meteorite impact crater located approximately 43 miles (69 km) east of Flagstaff, near Winslow in the northern Arizona desert of the United States. Because the US Department of the Interior Division of Names commonly recognizes names of natural features derived from the nearest post office, the feature acquired the name of "Meteor Crater" from the nearby post office named Meteor. The site was formerly known as the Canyon Diablo Crater, and the meteorite that created the crater is officially called the Canyon Diablo Meteorite, the name that is on all officially labelled fragments of the meteorite. Scientists refer to the crater as Barringer Crater in honor of Daniel Barringer who was first to suggest that it was produced by meteorite impact. The crater is privately owned by the Barringer family through their Barringer Crater Company, which proclaims it to be "the first proven, best-preserved meteorite crater on earth."
Despite its importance as a geological site, the crater is not protected as a national monument, a status that would require federal ownership. It was designated a National Natural Landmark in November 1967.
Meteor Crater lies at an elevation of about 1,740 m (5,709 ft) above sea level. It is about 1,200 m (4,000 ft) in diameter, some 170 m deep (570 ft), and is surrounded by a rim that rises 45 m (150 ft) above the surrounding plains. The center of the crater is filled with 210–240 m (700–800 ft) of rubble lying above crater bedrock. One of the interesting features of the crater is its squared-off outline, believed to be caused by pre-existing regional jointing (cracks) in the strata at the impact site.
The crater was created about 50,000 years ago during the Pleistocene epoch when the local climate on the Colorado Plateau was much cooler and damper. At the time, the area was an open grassland dotted with woodlands inhabited by woolly mammoths and giant ground sloths. It was probably not inhabited by humans; the earliest confirmed record of human habitation in the Americas dates from long after this impact.
The object that excavated the crater was a nickel-iron meteorite about 50 meters (54 yards) across, which impacted the plain at a speed of several kilometers per second. The speed of the impact has been a subject of some debate. Modeling initially suggested that the meteorite struck at a speed of up to 20 kilometers per second (45,000 mph), but more recent research suggests the impact was substantially slower, at 12.8 kilometers per second (28,600 mph). It is believed that about half of the impactor's 300,000 metric tons (330,000 short tons) bulk was vaporized during its descent, before it hit the ground. The impactor itself was mostly vaporized; very little of the meteorite remained within the pit that it had excavated.
Bremen, Germany. Orion's European Service Module is loaded on the Antonov airplane for transport to Kennedy Space Center.
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.

I changed the gender of the folds on the left side of the module to make the "arms" in 2 different colours [with duo-coloured papers]
The example here is from 7.5cm squares. If 2x1 or 3x1 papers are used, then there will be another whole range of variations. No, I am not going to go through all these again but may just add a couple of variations.
The Orion service module test article is installed in the Reverberant Acoustic Test Facility at NASA’s Plum Brook Station in Sandusky, Ohio. The blue structure sitting on top of the test article is a mass simulator that represents the Orion crew module.
The test exposed the article to sound pressure and vibration to simulate the intense sounds the Orion service module will be subjected to during launch and ascent into space atop the agency’s Space Launch System (SLS) rocket. This is part of a series of tests to verify the structural integrity of Orion’s service module for Artemis I, the spacecraft’s first flight atop SLS.

All the modules for the new setup 2009 to capture insects in flight are now ready. Just a few software adjusts now.
N scale town module -- various kits
Background
There is quite a tale about this module. This module was completed in 2006 while I was staying temporary at my parents. It was done just in time for Christmas as a static holiday display (imagine the guests going gaga over it). It was before the age of facebook and flickr which explains why I've never bothered to take pictures then. For the next 5 years this module sat under dust cover (garbage bags to be precise) as I moved to my own house. It has been in the supposèd hobby room since.
I haven't taken it out to display or played with it until now that I have restored some ordered to my hobby room -- which you'd see as the unadorned backdrop in these photos. With some minor rearranging and fixing of the disturbances from the move, you are now seeing this module for the first time in 5 years after it was first displayed to an invitation-only crowd.
Not the Full Story
Believe it or not this series of photos doesn't tell the full story. For nearly the entire length of this module there is an underground station underneath the town complete with platforms and four electrified tracks -- by that I mean live catenary. This is accessible from the back of this module. Altogether six tracks passes through this module.
Moreover, I have installed lights for the buildings and this module does light up. Unfortunately my ignorance with electricity means that I've taken out too many bulbs. This drastically decreased the life of the Christmas lights. Eventually I'll have to take the lights out for replacement. *yikes*
Why Winter?
Like most modules this was built on top of styrofoam blocks. I didn't intend this to be a winter module when I started out. But as I was running out of time to finish, the quickest way to hide blemishes was simply dusting the whole thing with "snow". This turned out perfect for a winter holiday scene.
It's gonna be a nightmare to remove the snow and plaster should I decide to change it back to a summer scene.
I have decided to name the module as, "Cubo Modules" Initially I wanted to call it "Cuboctahedron Module" because the first model I assembled from these modules was the Cuboctahedron. It is a very long name. Therefore, I shorten it to Cubo.
The models in this photo are assembled from the same modules. 3 modules to form the Prism, 6 for the Cuboctahedron, 12 for the Rhombicuboctahedron and 30 modules for the Rhombicosidodecahedron.
A place to haul smaller boats ashore. Larger rocks are removed and logs laid down to protect the keel and the bottom of the boat. If anyone knows an english word for this structure please tell.

Servo module, max 64 channels or 32 channels + 32 output leds as status line.
The servo motors are classified in 20 msec time slot. Each servo will have a time part of 2.5 msec, so 8 slots for a period of 20 msec. Each servo motor will have a max pwm pulse time of 2.5 msec. This results in a total of 64 units. If additional a status led are used, the number is limited to 32 servos+ 32 leds.
The upper picture shows a power plane for 16 servo motors. There are 2 separate power pins for the 5V servos. For now, I provide a 5V 4A power unit / power plane for 16 units.
This multiplexing greatly limits the number of I / O pins on the FPGA output side. Only 16 lines are needed for the 64 servos.

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
