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.
The engineering mockup of the Robotic Refueling Mission (RRM) module is currently on display within the press building at the Kennedy Space Center in Florida. The RRM mission is a joint effort between NASA and the Canadian Space Agency designed to demonstrate and test the tools, technologies, and techniques needed to robotically refuel satellites in space. Reporters have the opportunity to get a close-up view of the replica module and tools that are a part of the final shuttle mission payload.
Directed by customized controllers and algorithms, a powerful industrial robot (left) uses a Robotic Refueling Mission (RRM) tool (at end of blue arm) to perform precise and minute maneuvers on RRM flight hardware (right).

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.

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

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.
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.
