First module using the NELTC mainline standard. I really dig the wedge plate accent on the outside of the ballast. I am reasonably happy with the trees, but may tinker with the tops.
Ball detector module.
Can be used to count or detect the number of balls. Works with a hall chip built into the module. A small Neodym magnet is built into a rotating anchor. In order to measure a series of balls properly, a brake zone is built in. Without this braking zone the anchor will otherwise not have time to move back. The anchor has 2 extra holes of 4 mm. They can be used to place small steel axles as extra counterweight. However, I have tested it even without these extra weights and it works perfectly. The first hole of 4mm also serves to pull out the small magnet if you have the wrong polarity. I made a reference setup so that I have the correct polarity before pressing the magnet.
In the module extra height has been kept free to use Fischertechnik blocks. These are indicated on the drawing. Original Fischertechnik parts are always easier to connect with other parts. These extra parts are also shown in the drawing. The output of the module can be made via a straight connection or a 180 degree connection. All necessary blocks are also shown in the drawing.
For the hall connection I use a 3 pin female connetor. The wires of the hall can be easily connected without additional PCB. I swapped the 2 power pins of the hall output to the connector so the connector would have a standard connection: Output, +VCC, GND. This wiring then corresponds to that of a servo connection. The hall has an open collector output so it can easily be used on any kind of interface. Its power supply itself can be between 4V and 24V. The most commonly used voltage is 5V.
A drawing is also included with the timing results for a burst of 5 balls. You have to take into account that sometimes the speed can be quite high (pulses about 25 msec). You may need to sharpen the brake zone ( adjusts the input so that the ball can just pass) if your controller cannot handle this speed. This is the case for the TXT Controller Fischertechnik. I use my FPGA controller to read the pulses and it never has speed problems.
All parts are printed with the Flachforge Finder 3D printer. The filament used is PLA 1.7mm, 210 degree, Raft and Brim enabled, Infill 25%.

more than just blink. I added bits for a connector and regulating the power from 5v for the Atmega168 to 3.3v for LCD, accelerometer, etc.
I messed up the 3.3v voltage regulator and took a few tries bending the pins different ways before getting to work.
creating a series of connected modules of different angles of twist from the same axis. The twist is only along the x-y parameter keeping the top and bottom section the same with similar spacing, demonstrating a twisted grid created with mass customization.
Twisted forms provide better solutions against eccentric and non uniform multi direction loads compared to the usually 3 dimensional x-y-z grid arranged buildings.
okay sorry for more tech stuff, i'm just writing all this out so i won't forget when the final presentation comes. gahhh

Design for a stepper motor drive.
The stepper motor drive uses the TMC2100 modules from an old 3D printer (FlashForge Finder). I got this gift from a Fischertechnik forum member. The modules are controlled via a spi connection with my FPGA controller. The FPGA is connected to the Fischertechniek TXT Controller via an I2C line. The TMC2100 modules are in a fixed mode of the 3D printer, there is micro stepping used with 16 fine steps per step. Through the SPI connection I can send the ena, DIR, STEP, CFG0 and CFG4 pin. Because the modules are configured in 16 microsteps, the step pulses can be provided quite quickly. Therefore I controlled the SPI driver from a 4MHz clock so that only 13.5 usec is needed to scan all 24 inputs and outputs. This is much faster than the max step speed needed for the stepper.
The SPI goes to the FPGA chip. This is now programmed as a large I2C chip for the user. Besides this stepper driver there are also modules written for 16 motors, 72 inputs, 36 outputs, and 32 servo motors. All inputs can handle fairly fast pulses especially for quadrature encoders. The motors can run in 5 different modes and operate autonomously. The external I2C user only needs to send a few commands. Timing is no problem at all because the FPGA works much faster than the fastest micro controller. There are almost 1000 bytes of registers provided to support all functions. On the Fischertechnik side I have written a full lib to support all these functions. Through the Robopro software you can now write a program in a few minutes to the motors, servo steppers controls, reads inputs, status reads output line controls. I will give you more information about this later, but this data is so extensive that writing the manual takes a lot of time.

Edited Apollo 11 image of the Lunar Module Eagle from a distance. (I hesitate to guess the distance given the lack of atmosphere.)
A test version of the European Service Module at NASA’s Plum Brook Station in Sandusky, Ohio, USA. ESA’s module will power NASA’s Orion spacecraft to the Moon and beyond, providing propulsion, electricity, water, oxygen and nitrogen and thermal control.
This test article has the same structure and weight as the real thing but does not include the electronics and engines. It is being used to confirm the design before starting to build the flight version.
From a design perspective, the launch is one of the most demanding moments in a mission. Orion will sit atop the Space Launch System and more than 2500 tonnes of propellant. The vibrations and forces are intense until they reach the relative calm of space.
To ensure the service module can withstand these forces, it is placed on a large table that shakes and moves to recreate the vibrations of launch. Almost 1000 sensors monitor how the 35 tonne spacecraft flexes and withstands the stress. The blue wires carry the data during the tests for later analysis.

The tortoises of the island of Floreana went extinct after human invasion (Floreana is probably the most ecologically devastated of the islands in the archipelago, which was sad to see in a lot of ways), but recently a population of tortoises has been reintroduced from other islands (hence the species/subspecies status is uncertain in these photos, as with those I took on Isabela, also re-introduced individuals). This individual was given some food by the local conservation group, where these tortoises are being protected and reared.

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.
What to do with your old Entertainment Books? Make a Sonobe module out of them of course! The paper is stiff enough to stay sturdy but is still able to be folded. The coupons are nearly square (just a little trimming required) and there's a variety of colours. I'm still planning what to do with the gold section.
Donations of your old Entertainment Books (who uses all their vouchers anyway?) happily accepted! If only I'd thought of doing this sooner I would have had years worth of books to use as materials.
This model was based on a Sonobe Module Variation.

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 top and left models are rejects. All folded from 9cm Square Kami.
For the top model, two 45 degrees mountain folds are added on the other end of each module to make a 9-pointed Star...I may make a better one...later.
This is my last version of the diagrams for the square cross module. Only the way to fold the module is a little bit different to my first version. Here I have also the opening of the wireframe module pocket (step 5), which is common for the polygon cross modules.
I think I can say, that it was Carmen Sprung, during my workshop at the Weimar convention, who call me attention to this perhaps easier way of folding.
I also add the diagrams for the two simple windmill variations.
For the joining of all the modules follow : www.flickr.com/photos/eisfold/8618006029/.
Folded and assembled from 6 pieces of 15cm square Kami. 3 colours, 2 of each are used. No cuts and no glue. This module was created in 1988 and published in my self-published book, "Modular Origami". The assembled model is kind of a truncated cube.

The day started sunny and calm, but by the time I had done my chores it was cloudy and windy so didn't go on my planned excursion to a waterfall.
Decided to have my first go at Camera School Module 3 indoors. As it was cloudy outside, it was even darker inside and it was impossible to get the degree of blurred water, yet showing a sense of movement, with the recommended CS settings. I found around 1/15-1/30 portrayed this best, but to achieve this a high ISO, coupled with a small F number was required. Another difficulty I had was with the large dynamic range between the dark sink/tiles, and the bright water and the need for a reflector which lightened the darker bits, but also blew the highlights. An ND filter was not required in these dull conditions.
I won't therefore be using any of these shots for homework, but put them up as my first venture into this module. On a bright day this setup might work and I might give it another go with different composition and crockery/containers.
