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

Engineers rotate the Pressurized Cargo Module of the Cygnus spacecraft, built by Orbital ATK, it to a vertical position in its work stand as so it can be joined to the service module. The processing is taking place inside Space Station Processing Facility at NASA's Kennedy Space Center in Florida. The spacecraft, which flies without a crew, has been loaded with equipment, supplies and research experiments that it will ferry to the International Space Station in orbit about 280 miles above Earth. The Cygnus is to launch atop a United Launch Alliance Atlas V rocket. Photo credit: NASA/Dmitri Gerondidakis
The third (pictured) and fourth European Service Modules are currently in production at Airbus facilities in Bremen, Germany. They are a key element of the Orion spacecraft, the first to return humans to the Moon since the 1970s.
These modules provide the spacecraft with propulsion, power and thermal control, and will supply astronauts with water and oxygen. The Orion spacecraft is composed of a European Service Module, a Crew Module Adapter and a Crew Module. The latter two components are provided by NASA.
Powering flights to the Moon is a collaborative effort. The components and hardware used in the European Service Modules are built and supplied by more than twenty different companies from ten different countries in Europe.
When ready for launch, each module will have a total mass of 13500 kg, almost two-thirds of which is propellant (rocket fuel). More than 11 km of cables are needed to send commands and receive information from the many on-board sensors. As can be seen in the photo, tie-wraps (yellow) come in handy when it comes to keeping all these cables organised.
The first European Service Module is already attached to the Orion spacecraft and awaiting launch for Artemis I later this year. The second European Service Module has been formally transferred to NASA and is completing integration at the Operations and Checkout building at the Kennedy Space Center. It will be used on the Artemis II mission, the first crewed mission to fly all the way to the Moon in half a century.
By delivering six European Service Modules, ESA is ensuring NASA’s Artemis programme continues to develop a sustainable presence on and around the Moon in international partnership.

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.
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
Technicians at the Airbus facility in Bremen, Germany weigh the European Service Module ahead of shipment to Kennedy Space Center. The service module will depart Germany on November 5th, 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.

Module 3 of a modular microscale Space Base on Mars. This is the Rovers Bay (seen here empty).
find more pics in the Mars Base set.
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.

The Shuttle Discovery, NASA's flagship orbiter, heads into space for the 39th and final time February 24 at 4:50pm EST. STS-133 launched into a beautifully clear late-afternoon sky, taking to the space station Leonardo, formerly one of the two flown resuable Multipurpose Logistics Modules (MPLM) that visited the ISS on seven previous shuttle missions since 2001, and now converted into a permanent storage closet for the station known as the Pressurized Multipurpose Module (PMM). This was the last US-launched module added to the space station.

Scenes from the Artemis I mission going beyond the Moon and back to Earth.
After its launch on November 16, the Orion spacecraft has been heading toward the Moon on its 25-day Artemis I mission. Orion was launched by the NASA Space Launch System (SLS) rocket at 7:47 CET (06:47 GMT) from launchpad 39B at NASA’s Kennedy Space Center in Florida, USA.4
The European Service Module is powering Orion, providing propulsion, temperature control, electricity as well as storage and delivery for essential supplies such as fuel, water and air. This first Artemis mission is an uncrewed test mission, putting the spacecraft through its paces preparing to send astronauts forward to the Moon.
The uncrewed mission to learn as much as possible about Orion and its European Service Module’s performance. The primary objectives are to demonstrate Orion’s heat shield on reentry, demonstrate operations and facilities during all mission phases, and retrieve the spacecraft after splashdown.

The crew and service module for Exploration Mission-1 continue preparations for mating inside the O&C High Bay. Along side, the pressure vessel for Exploration Mission-2 is undergoing install of its secondary structure.
This shows the module tabs implementation on Yahoo!'s front page. The active tab control's text is a different color, and the active tab control is connected to the active pane. The module tabs implementation also maintains the design pattern's metaphor by making it look like the inactive tab controls are farther away from the screen than the active tab - resembling stacked folders.

This is another simple Module which I recently discovered. Modules from 5 to n can be assembled but the easiest to assemble is 8 Modules. I have not tried out anything more than 8 Modules but from what I see, 16 or more is definitely possible. CP later.
